<p>Today's <strong>Image of the Day</strong> from the <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">European Space Agency</a> features the spiral galaxy IC 5332, which is located over 29 million light-years away from Earth and spans approximately 66,000 light-years in diameter. This makes it notably smaller than our <a href="https://www.earth.com/news/large-amount-of-dark-matter-may-be-missing-from-the-milky-way/" target="_blank" rel="noreferrer noopener">Milky Way</a>, which is about a third larger.&nbsp;</p>



<h2 class="wp-block-heading" id="h-unprecedented-look-at-ic-5332">Unprecedented look at IC 5332</h2>



<p>In a stunning photo release by NASA and ESA in 2022, the spiral galaxy IC 5332 was presented in an unprecedented level of detail in images captured by the <a href="https://www.earth.com/news/james-webb-captures-incredible-new-image-of-uranus/" target="_blank" rel="noreferrer noopener">James Webb Space Telescope</a>.</p>



<p>This feat was made possible through the use of the Mid-InfraRed Instrument (MIRI), which captures images in the mid-infrared spectrum.</p>



<h2 class="wp-block-heading" id="h-unique-perspective-from-earth">Unique perspective from Earth</h2>



<p>One of the most striking features of IC 5332, as revealed by these observations, is its almost perfect face-on orientation relative to Earth. </p>



<p>This unique perspective allows astronomers to clearly observe and admire the symmetrical arrangement of its spiral arms.</p>



<h2 class="wp-block-heading" id="h-webb-unveils-ic-5332-in-new-light">Webb unveils IC 5332 in new light</h2>



<p>The clarity of these images represents a significant advancement over previous observations made by the Hubble Space Telescope, which imaged IC 5332 in ultraviolet and visible light.&nbsp;</p>



<p>While Hubble’s images revealed the galaxy’s symmetrical spiral arms, James Webb’s MIRI has unveiled these structures as a complex web of gas that emits infrared light at various temperatures.</p>



<h2 class="wp-block-heading" id="h-the-miri-instrument-on-james-webb-nbsp">The MIRI instrument on James Webb&nbsp;</h2>



<p>Capturing this range of infrared light is no simple task. It requires highly specialized instruments that must be maintained at extremely cold temperatures.&nbsp;</p>



<p>The MIRI instrument on the James Webb Space Telescope is specifically designed for this purpose and performs exceptionally well. Its capabilities allow astronomers to see aspects of <a href="https://www.earth.com/news/james-webb-captures-galaxies-that-are-too-old-to-exist/" target="_blank" rel="noreferrer noopener">galaxies</a> that are otherwise hidden in other wavelengths.</p>



<p>The detailed images provided by MIRI offer more than just a visual spectacle; they provide valuable data about the composition and temperature of the gases that make up the spiral arms of IC 5332. This can help scientists understand the processes of star formation within the galaxy and how these processes compare to those in our own <a href="https://www.earth.com/news/stars-at-the-edge-of-our-milky-way-galaxy-travel-more-slowly/" target="_blank" rel="noreferrer noopener">Milky Way</a>.</p>



<h2 class="wp-block-heading" id="h-webb-finds-hidden-features-of-the-universe-nbsp">Webb finds hidden features of the universe&nbsp;</h2>



<p>Moreover, the images of IC 5332 serve as a critical test of the James Webb Space Telescope’s capabilities in observing the universe in infrared light. As astronomers continue to deploy Webb’s full suite of instruments to explore the cosmos, it is expected that many more hidden features of the universe will be revealed.</p>



<p>The information provided by the <a href="https://www.earth.com/news/webb-telescope-discovers-second-most-distant-galaxy-in-pandoras-cluster/" target="_blank" rel="noreferrer noopener">James Webb Space Telescope</a> not only expands our understanding of the cosmos but also enhances our appreciation for the complex and beautiful structures that exist in our universe.&nbsp;</p>



<p>We can anticipate many more insights from Webb that will deepen our understanding of the fundamental processes governing galaxies and the broader universe.</p>



<h2 class="wp-block-heading" id="h-more-about-spiral-galaxies-like-ic-5332">More about spiral galaxies like IC 5332</h2>



<p>Spiral galaxies are some of the most visually striking objects in the universe, characterized by their rotating arms that extend from a central nucleus, giving them a distinct spiral appearance.&nbsp;</p>



<p>These galaxies are primarily made up of a flat, rotating disk containing stars, gas, and dust, and a central concentration of stars known as the bulge. These are often surrounded by a much fainter halo of stars, many of which reside in globular clusters.</p>



<p>Spiral galaxies differ from other galaxy types, such as elliptical and irregular galaxies, in their structure and content. The spiral arms are sites of ongoing star formation and are brighter than the rest of the disk because of the young, hot stars that are typically found there. The arms appear distinct because of their density waves, which compress the gas and dust, leading to star formation.</p>



<p>The rotation of the spiral arms also contributes to the galaxy's flat shape due to the centrifugal forces acting on the disk. The central bulge can vary in size and often contains older, red stars.&nbsp;</p>



<h2 class="wp-block-heading" id="h-barred-spiral-galaxies-nbsp">Barred spiral galaxies&nbsp;</h2>



<p>Some spiral galaxies have a bar-shaped structure that extends from the central bulge, making them barred spirals. This bar affects the motion of stars and gas within the galaxy and can influence star formation activity.</p>



<p>The Milky Way, where our solar system resides, is an example of a barred spiral galaxy. Spiral galaxies are an important focus of study because they contain a significant amount of visible matter and play a crucial role in understanding the formation and evolution of galaxies.&nbsp;</p>



<p>Their distinct features also make them particularly useful for studying the laws of physics under extreme conditions, such as high densities and velocities.</p>

Webb unveiled spiral galaxy IC 5332 in new light

Today's Image of the Day from the European Space Agency...

<p>Today's <strong>Image of the Day</strong> from <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA Earth Observatory</a> features the Corbassière glacier, a high-altitude glacier in Switzerland. The glacier originates on the northern slope of the Grand Combin, which is one of the highest peaks in the Pennine Alps.</p>



<p>Collectively, the <a href="https://www.earth.com/news/alpine-glaciers-will-lose-half-of-their-volume-by-2050/" target="_blank" rel="noreferrer noopener">alpine glaciers</a> of Switzerland have lost more than half of their volume since the 1930s.</p>



<h2 class="wp-block-heading" id="h-natural-archives-of-past-climate">Natural archives of past climate </h2>



<p>"Glaciers are natural archives of past climate. In their frozen layers lies evidence of Earth’s changing temperature and atmospheric composition. But as the climate warms, some of the longest records of our changing planet are melting away," said NASA.</p>



<p>"In just over two decades, Corbassière has shrunk in area and surface mass. The glacier was darker in 2023 due to lack of snow, and the glacier’s tongue had retreated."</p>



<h2 class="wp-block-heading" id="h-ice-cores-from-the-corbassiere-glacier">Ice cores from the Corbassière glacier</h2>



<p>To reconstruct past concentrations of atmospheric <a href="https://www.earth.com/news/how-do-aerosols-impact-the-climate/" target="_blank" rel="noreferrer noopener">aerosols</a>, a team of scientists analyzed ice cores that were collected from the Corbassière glacier in 2018 and 2020. </p>



<p>Aerosols are tiny airborne particles that are deposited in the ice. "Such information from glaciers around the world can provide clues about past environmental conditions thousands of years ago," noted NASA.</p>



<p>"Ice cores contain ammonium, nitrate, and sulfate ions - signatures of aerosols lacing the snow that’s deposited on glaciers year after year. Ion concentrations are lower in winter than in summer because less polluted air can rise from the valley when the air is cold."</p>



<p>When the researchers analyzed the ice core from 2018, they found seasonal fluctuations in the amount of ion deposits - which is what they expected to find.&nbsp;</p>



<p>"But when we went to core the glacier in 2020, we noticed melting on the surface right away,” said Margit Schwikowski, an environmental chemist at <a href="https://www.psi.ch/en" target="_blank" rel="noreferrer noopener">Paul Scherrer Institute</a> in Switzerland.&nbsp;</p>



<h2 class="wp-block-heading" id="h-rapid-surface-melting-on-corbassiere-glacier">Rapid surface melting on Corbassière glacier</h2>



<p>The experts determined that melting on the glacier's surface likely penetrated the glacier layers below and carried away the aerosol ions. "This melting rendered the core unusable in the team’s research, and other attempts to core the glacier had the same result. The valuable information stored in the ice was destroyed," explained NASA.</p>



<p>Schwikowski has joined a team of other experts in an effort to preserve cores from the last remaining glaciers. Led by the <a href="https://www.ice-memory.org/" target="_blank" rel="noreferrer noopener">Ice Memory Foundation</a>, the goal of the project is to obtain ice cores from 20 endangered glaciers around the world in 20 years and collect them in a global <a href="https://www.earth.com/news/antarcticas-ice-has-a-history-of-rapid-and-unexpected-changes/" target="_blank" rel="noreferrer noopener">climate archive</a>.</p>



<p>“Glaciers are retreating worldwide, and we may find similar issues at other sites,” said Schwikowski. She added that even at the highest altitudes in the Alps, "glaciers are on the verge of becoming unsuitable as natural paleo-archives."</p>



<h2 class="wp-block-heading">More about the Corbassière Glacier</h2>



<p>The Corbassière Glacier is a captivating natural feature located in the Swiss Alps, part of the canton of Valais. This glacier stretches over approximately 9 kilometers, making it one of the significant glaciers in the region. It originates from the Grand Combin, an imposing mountain massif that reaches heights of over 4,300 meters, contributing greatly to the glacier's nourishment through snow and ice accumulation.</p>



<p>A distinct feature of the Corbassière Glacier is its accessibility and the dramatic scenery it offers, which attracts many hikers and nature enthusiasts. One of the most notable attractions near the <a href="https://www.earth.com/news/doomsday-glacier-seems-to-have-lost-its-ability-to-recover/" target="_blank" rel="noreferrer noopener">glacier</a> is the Corbassière footbridge, a 210-meter long suspension bridge that provides stunning views of the glacier and the surrounding peaks. </p>



<p>This bridge not only enhances the experience for visitors but also serves as a crucial observation point for scientists studying glacier dynamics and the effects of climate change.</p>



<h2 class="wp-block-heading">The Swiss Alps&nbsp;</h2>



<p>The Swiss <a href="https://www.earth.com/news/snow-cover-in-the-alps-could-soon-be-cut-in-half/" target="_blank" rel="noreferrer noopener">Alps</a> are a majestic and expansive mountain range that stretches across the southern part of Switzerland, forming a part of the greater Alpine region that spreads across several countries in Europe. </p>



<p>Renowned for their stunning beauty and formidable peaks, the Swiss Alps are not just a geographical landmark but also a cultural symbol of Switzerland, epitomizing its identity as a nation of scenic landscapes and outdoor adventure.</p>



<p>The region is famous for its dramatic scenery, including towering mountains, pristine lakes, and picturesque valleys. Among these peaks are some of the highest in Europe, such as the Dufourspitze, part of the Monte Rosa massif, which is the highest point in Switzerland. </p>



<p>The Matterhorn, perhaps the most iconic of all Swiss mountains, is celebrated for its unique, pyramid-like shape and is a magnet for climbers and tourists alike.</p>

Corbassière glacier: Earth's climate archives are melting away

Today's Image of the Day from NASA Earth Observatory features...

<p>Today's <strong>Image of the Day</strong> from <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA Earth Observatory</a> features dust streaming from Lago Colhué Huapi, a shallow endorheic lake located in the Chubut Province in southern Argentina.</p>



<p>"Strong northwesterly winds often race down the eastern side of the Andes Mountains and whip across the central Patagonian Desert. In the process, they sometimes lift dust from Argentina’s drying Lago Colhué Huapi, fueling intense dust storms," said NASA.</p>



<p>"Lago Colhué Huapi is a particularly rich source of dust because the shallow lake regularly grows and shrinks with variations in the flow of the Senguer River and the pace of evaporation. When lake water levels are low, as they were when MODIS captured this image, fine-grained, lightweight particles are easily transported by the wind."</p>



<h2 class="wp-block-heading" id="h-dust-activity-from-lago-colhue-huapi">Dust activity from Lago Colhué Huapi</h2>



<p><a href="https://www.earth.com/news/dust-storms-in-the-gulf-of-alaska-help-shape-the-global-climate/" target="_blank" rel="noreferrer noopener">Dust storms</a> in this region are most common during the summer months from December to March. There are 15 to 30 dust storms in a typical year. </p>



<p>"Dust storms are frequent and persistent enough in this area that they have exposed an open-air archaeological site along the lake’s edge," said NASA.</p>



<p>"The Puesto Roberts 1 site, located in an old floodplain on the southeast side of Lago Colhué Huapi, was first identified in 2019 when archaeologists noticed that winds had exposed a five-centimeter layer of sandy loam soil littered with stone tools and the bones of a wild species of llama called guanaco."</p>



<p>"Archaeologists identified 427 artifacts at the site - including stone cutting blades, milling tools, scrapers, and egg-shaped bola stones used for hunting - spread across 15 square meters, according to a 2022 study led by Heidi Hammond, an archaeologist at the National University of the Patagonia San Juan Bosco."</p>



<h2 class="wp-block-heading" id="h-more-about-lago-colhue-huapi">More about Lago Colhué Huapi</h2>



<p>This lake is an interesting geographical feature primarily because it acts as a seasonal sink for the Senguerr River, which in turn gathers waters from various smaller streams in the region.&nbsp;</p>



<h3 class="wp-block-heading" id="h-size">Size</h3>



<p>Due to its shallow nature, the size of Lago Colhué Huapi can vary significantly with the seasons and the amount of water it receives from its sources. During times of drought or reduced rainfall, the <a href="https://www.earth.com/news/climate-change-is-pushing-lakes-to-their-boiling-point/" target="_blank" rel="noreferrer noopener">lake</a> can shrink considerably, affecting the local ecosystem and the wildlife that depends on it.</p>



<h3 class="wp-block-heading" id="h-climate">Climate</h3>



<p>The lake's surroundings are characterized by a semi-arid climate, which influences the type of vegetation and animal life that can thrive in the area. Despite the harsh conditions, the region around Lago Colhué Huapi supports a variety of bird species, making it a site of interest for birdwatchers and naturalists.</p>



<h3 class="wp-block-heading" id="h-environmental-challenges">Environmental challenges </h3>



<p>In recent years, Lago Colhué Huapi has faced environmental challenges, including the impact of <a href="https://www.earth.com/news/alarming-study-most-of-the-worlds-largest-lakes-are-quickly-losing-water/" target="_blank" rel="noreferrer noopener">climate change</a>, which has led to lower water levels and increased salinity. These changes pose threats to the lake's ecological balance and the species that inhabit its waters and shores. The situation at Lago Colhué Huapi serves as a reminder of the broader environmental issues facing water bodies in arid and semi-arid regions around the world.</p>

Dust streams from Lago Colhué Huapi in Argentina 

<p>Today's <strong>Image of the Day</strong> from the <a href="https://www.esa.int/" target="_blank" rel="noreferrer noopener">European Space Agency</a> features the star-forming region NGC 604, which is located 2.73 million light-years away from Earth in the Triangulum Galaxy (M33). The image was captured by the James Webb Space Telescope.</p>



<p>By studying regions like NGC 604, astronomers can gain insights into the complex interactions between stars and the interstellar medium, as well as the conditions that lead to the birth of stars. This, in turn, helps in understanding the evolution of <a href="https://www.earth.com/news/galaxies-like-our-own-milky-way-are-not-unique/" target="_blank" rel="noreferrer noopener">galaxies</a> and the universe as a whole.</p>



<h2 class="wp-block-heading" id="h-massive-stars-of-ngc-604">Massive stars of NGC 604</h2>



<p>"Sheltered among NGC 604’s dusty envelopes of gas are more than 200 of the hottest, most massive kinds of stars, all in the early stages of their lives," said ESA.</p>



<p>"These types of stars are known as B-types and O-types, the latter of which can be more than 100 times the mass of our own Sun. It’s quite rare to find this concentration of them in the nearby Universe. In fact, there’s no similar region within our own Milky Way galaxy."</p>



<p>"This concentration of massive stars, combined with its relatively close distance, means NGC 604 gives astronomers an opportunity to study these objects at a fascinating time early in their life."</p>



<h2 class="wp-block-heading" id="h-gigantic-region-of-ionized-hydrogen">Gigantic region of ionized hydrogen</h2>



<p>NGC 604 is one of the largest known regions of ionized hydrogen, also known as an H II region. This nebula is significantly larger than the Orion Nebula, which is one of the most well-known H II regions in our own <a href="https://www.earth.com/news/large-amount-of-dark-matter-may-be-missing-from-the-milky-way/" target="_blank" rel="noreferrer noopener">Milky Way galaxy</a>. </p>



<p>NGC 604 spans about 1,500 light-years across, making it one of the largest H II regions in the Local Group of galaxies, which includes the Milky Way, the Andromeda Galaxy, and about 54 other smaller galaxies. </p>



<h2 class="wp-block-heading" id="h-ngc-604-starburst-phenomenon">NGC 604 starburst phenomenon </h2>



<p>Within NGC 604, there are hundreds of young, hot, massive <a href="https://www.earth.com/news/stars-at-the-edge-of-our-milky-way-galaxy-travel-more-slowly/" target="_blank" rel="noreferrer noopener">stars</a>. These stars have ionized the surrounding gas, causing it to glow and creating the nebula. The region is a prime example of a starburst phenomenon, where stars form at a much higher rate than in typical galactic conditions.</p>



<p>“The bright orange streaks in this image signify the presence of carbon-based molecules known as polycyclic aromatic hydrocarbons, or PAHs," explained ESA.</p>



<p>"As you travel further from the immediate cavities of dust where the star is forming, the deeper red signifies molecular hydrogen. This cooler gas is a prime environment for star formation. Ionized hydrogen from ultraviolet radiation appears as a white and blue ghostly glow."</p>



<h2 class="wp-block-heading" id="h-more-about-star-formation">More about star formation </h2>



<p>Star formation is crucial for the evolution of galaxies and the synthesis of heavy elements. Elements heavier than helium are created in the cores of stars and spread throughout the <a href="https://www.earth.com/news/ancient-stars-shakti-shiva-shaped-milky-way-galaxy/" target="_blank" rel="noreferrer noopener">galaxy</a> when stars reach the end of their lives and expel their material, either gently through winds or violently via supernova explosions. This enriching process allows for the formation of new stars and planets, and ultimately, the potential for life.</p>



<h2 class="wp-block-heading" id="h-process-of-star-formation">Process of star formation</h2>



<h3 class="wp-block-heading">Cloud collapse</h3>



<p>The process begins when part of a molecular cloud becomes unstable and starts to collapse under its own gravity. This can be triggered by events like shock waves from nearby <a href="https://www.earth.com/news/supernova-explosions-could-damage-distant-planets/" target="_blank" rel="noreferrer noopener">supernovae</a>, galactic collisions, or the influence of other massive stars.</p>



<h3 class="wp-block-heading">Formation of a protostar</h3>



<p>As the cloud collapses, it fragments into smaller clumps. Each clump will eventually form one or more stars. The material within these clumps continues to fall inward, heating up as it does so, eventually forming a warm core called a protostar. At this stage, the protostar is not yet hot enough for nuclear fusion, the process that powers stars, to occur.</p>



<h3 class="wp-block-heading">Accretion disk</h3>



<p>Around the protostar, material from the surrounding cloud continues to fall inward, forming a rotating disk. This material slowly accretes onto the protostar, increasing its mass.</p>



<h3 class="wp-block-heading">Nuclear fusion begins</h3>



<p>Once the core of the protostar reaches a high enough temperature and pressure, hydrogen atoms begin to fuse into helium, releasing energy in the process. This marks the transition from a protostar to a main sequence star, like our Sun.</p>



<h3 class="wp-block-heading">Main sequence and beyond</h3>



<p>The star will spend the majority of its life in the main sequence stage, where it balances the gravitational forces trying to collapse it and the outward pressure from nuclear fusion. </p>



<p>Eventually, the star will exhaust its hydrogen fuel. Its subsequent evolution will depend on its initial mass, leading to various end stages such as red giants, supernovae, neutron stars, or black holes.</p>

NGC 604 is home to hundreds of hot, massive stars

<p>Today's <strong>Image of the Day</strong> from <a href="https://earthobservatory.nasa.gov/" target="_blank" rel="noreferrer noopener">NASA Earth Observatory</a> features thick haze over Thailand during the fire season. The photograph was captured by the VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite on March 16, 2024.</p>



<h2 class="wp-block-heading" id="h-waves-of-smoke-and-haze">Waves of smoke and haze</h2>



<p>"Each year in January and February, satellites begin to detect waves of smoke and fire in Southeast Asia, particularly in highland forests in Cambodia, Laos, Myanmar, and Thailand. Fire activity continues to increase through March and April, reaches a peak during the height of the dry season, and then fades in May with the start of the rainy season," noted NASA.</p>



<p>"Individual fires are usually small and short-lived. But they are often so numerous that smoke, along with air pollution from rural and urban areas, mixes to produce thick layers of haze that blanket the landscape." </p>



<p>"Such hazes contain mixtures of small airborne particles called aerosols and gaseous pollutants such as nitrogen dioxide, sulfur dioxide, carbon monoxide, and ozone that degrade air quality and have harmful health effects."</p>



<h2 class="wp-block-heading" id="h-haze-in-thailand-nbsp">Haze in Thailand&nbsp;</h2>



<p>An international field campaign - the Airborne and Satellite Investigation of Asian Air Quality (ASIA-AQ) - was recently launched to investigate the haze in Thailand.</p>



<p>"During the last two weeks of March 2024, NASA’s DC-8 and Gulfstream III aircraft flew several flights over Chiang Mai, Bangkok, and rural areas surrounding the cities to sample air quality with several sensors. At the same time, satellites observed the haze from above," said NASA.</p>



<p>James Crawford, ASIA-AQ’s principal investigator, said the team is collaborating closely with national and local government entities in Thailand.</p>



<p>“The goal is to take as many simultaneous measurements of pollutants as possible from the ground, air, and space,” said Crawford. The team will use the data to gain a better understanding of how the haze forms, evolves chemically over time, and moves throughout the region.</p>



<h2 class="wp-block-heading" id="h-haze-and-public-health-in-thailand">Haze and public health in Thailand </h2>



<p>According to media reports, nearly 200,000 people have been hospitalized this year due to air quality in the region, with over 1.3 million people falling ill since January.&nbsp;</p>



<h3 class="wp-block-heading" id="h-root-causes">Root causes</h3>



<p>The root causes of the haze include agricultural burning, particularly of corn fields, as part of slash-and-burn practices to prepare land for the next planting cycle. This is exacerbated by the dry season when there's little rain to wash the pollutants away. </p>



<p>The situation is worsened by industrial emissions and vehicle fumes, particularly in urban areas like Bangkok​.</p>



<h3 class="wp-block-heading" id="h-sustainable-solutions-are-needed">Sustainable solutions are needed</h3>



<p>Efforts to address the crisis have been complex, involving local and transboundary issues. Much of the agricultural burning occurs not only within Thailand but also in neighboring countries like Myanmar and Laos, contributing to the transboundary nature of the haze. </p>



<p>Activists and local communities have called for sustainable solutions that do not exacerbate the poverty of smallholder farmers, emphasizing the need for affordable and realistic alternatives to burning​.</p>



<h3 class="wp-block-heading" id="h-mitigation-measures-nbsp">Mitigation measures&nbsp;</h3>



<p>The Thai government has implemented a no-burning rule until the end of April to combat wildfires and haze, but enforcement and effectiveness remain challenges​​. </p>



<p>Some measures taken to mitigate the immediate effects of pollution in urban areas include spraying water and seeding clouds to encourage rain, although these have had limited success​​.</p>



<p>This ongoing environmental crisis has sparked widespread concern among citizens, who are increasingly using public interest litigation to hold companies and the government accountable for environmental commitments. </p>



<p>With recent political changes, there is hope that the new administration will take more decisive action against the haze, possibly through more stringent regulations and international cooperation​​.</p>



<h2 class="wp-block-heading" id="h-health-impacts-of-haze">Health impacts of haze</h2>



<p>Haze poses several health hazards for those exposed to it, particularly when it contains fine particulate matter (PM2.5). Here are some of the main health risks associated with exposure to haze:</p>



<h3 class="wp-block-heading" id="h-respiratory-problems">Respiratory problems</h3>



<p>Haze can aggravate conditions such as asthma, bronchitis, and other chronic obstructive pulmonary diseases (COPD). The fine <a href="https://www.earth.com/news/heatwaves-and-air-pollution-may-double-fatal-heart-attack-risk/">particles</a> can penetrate deep into the lungs, causing inflammation and reducing lung function.</p>



<h3 class="wp-block-heading" id="h-cardiovascular-issues-and-haze">Cardiovascular issues and haze</h3>



<p>Exposure to fine particulate matter can also affect the cardiovascular system, leading to increased risk of heart attacks, strokes, and high blood pressure. Particles can affect blood vessel function and promote the formation of blood clots.</p>



<h3 class="wp-block-heading" id="h-eye-irritation">Eye irritation</h3>



<p>Haze can cause eye irritation, leading to conditions such as conjunctivitis (pink eye) or exacerbated symptoms in people with existing eye conditions.</p>



<h3 class="wp-block-heading" id="h-skin-problems">Skin problems</h3>



<p>For some people, exposure to <a href="https://www.earth.com/news/air-pollution-will-increase-dramatically-in-a-hotter-climate/">polluted air</a> can cause skin irritation or exacerbate skin conditions like eczema or psoriasis.</p>



<h3 class="wp-block-heading" id="h-reduced-immune-function">Reduced immune function</h3>



<p>There is evidence to suggest that prolonged exposure to polluted air can weaken the immune system, making individuals more susceptible to infections.</p>



<h3 class="wp-block-heading" id="h-impact-on-mental-health">Impact on mental health</h3>



<p>There are growing concerns about the impact of air pollution on <a href="https://www.earth.com/news/air-pollution-linked-to-multiple-chronic-health-conditions/">mental health</a>, with studies suggesting a link between exposure to polluted air and an increased risk of depression and anxiety.</p>



<h3 class="wp-block-heading" id="h-pregnant-women-and-children">Pregnant women and children</h3>



<p>Pregnant women, children, and the elderly are particularly vulnerable to the effects of haze. There may be increased risks of preterm birth and low birth weight in babies, and children may experience delayed development and reduced lung function.</p>



<p>The health impacts of haze can be mitigated by staying indoors on days when air quality is particularly poor, using air purifiers, wearing masks designed to filter out fine particles, and following local health advisories.</p>

Haze pollution is an environmental crisis in Thailand

<p>Today's <strong>Image of the Day</strong> from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> features smoke streaming from a fire near the border of Oaxaca and Chiapas in southern Mexico.</p>



<p>"As Mexico entered peak fire season in March 2024, dry and warm conditions helped fuel the flames of more than 100 active blazes across the country," said NASA.</p>



<p>"According to Mexico’s National Forestry Commission (CONAFOR), there were 120 actively burning fires across Mexico on March 27. Preliminary data indicated that fires that day affected more than 7,000 hectares (27 square miles) across 19 of Mexico’s 31 states."</p>



<h2 class="wp-block-heading" id="h-fire-season-in-mexico-nbsp">Fire season in Mexico&nbsp;</h2>



<p>Fire season in Mexico is a period marked by a heightened risk of wildfires, primarily occurring from January through June, with the peak usually observed between March and May. This timing is largely due to the country's climatic patterns, where the end of the dry season and the beginning of the warmer spring months create conditions ripe for fires.&nbsp;</p>



<p>These conditions include dry vegetation, which serves as ample fuel for wildfires, and the onset of warmer temperatures, which can exacerbate the risk of fires starting and spreading.</p>



<p>Mexico's varied topography and climatic zones mean that fire risk and behavior can differ significantly across the country. However, areas with extensive forest cover, such as the pine-oak forests in the northern and central regions, are particularly vulnerable during the fire season.&nbsp;</p>



<p>Human activities, including agricultural practices such as the clearing of land through burning (known as "slash and burn"), contribute significantly to the ignition of these wildfires. Additionally, accidental fires caused by campfires, cigarettes, or even deliberate arson add to the annual fire count.</p>



<h2 class="wp-block-heading" id="h-intense-fire-seasons-across-the-globe-nbsp">Intense fire seasons across the globe&nbsp;</h2>



<p>The phenomenon of more <a href="https://www.earth.com/news/record-breaking-wildfire-years-are-just-getting-started/">intense fire seasons</a> across the globe is a complex and multifaceted issue that intertwines with climate change, land management practices, and human activities.&nbsp;</p>



<p>Over the past decades, several regions around the world have experienced unprecedented wildfires in both frequency and intensity. These fires have resulted in devastating impacts on ecosystems, wildlife, <a href="https://www.earth.com/news/wildfire-smoke-is-an-underestimated-threat-to-public-health/">air quality</a>, and human settlements.</p>



<h3 class="wp-block-heading" id="h-north-america-nbsp">North America&nbsp;</h3>



<p>In North America, particularly in the United States and Canada, fire seasons have become significantly longer and more destructive.&nbsp;</p>



<p>The combination of prolonged droughts, higher temperatures, and an increase in the amount of dead and dry vegetation has turned vast areas into tinderboxes, ready to ignite with a single spark.&nbsp;</p>



<p>Notably, the wildfires in <a href="https://www.earth.com/news/what-caused-the-devastating-2020-fire-season-in-california/">California</a> have set records for their sheer size and the amount of destruction they've caused, burning millions of acres and destroying thousands of homes.</p>



<h3 class="wp-block-heading" id="h-australia-nbsp">Australia&nbsp;</h3>



<p>Australia's fire season during 2019-2020, known as the Black Summer, was one of the most severe in the country's history. A prolonged drought and extreme heatwaves contributed to widespread <a href="https://www.earth.com/news/australian-bushfires-triggered-rare-multi-year-la-nina/">bushfires</a> that burned through millions of hectares, destroyed over 3,000 homes, and led to the loss of at least 33 lives.&nbsp;</p>



<p>The environmental impact was catastrophic, with significant losses to wildlife and biodiversity, including an estimated billion animals killed.</p>



<h3 class="wp-block-heading" id="h-amazon-rainforest-nbsp">Amazon rainforest&nbsp;</h3>



<p>In the Amazon rainforest, often referred to as the Earth's lungs, there has been an alarming increase in fires. These are largely attributed to deforestation and agricultural practices.&nbsp;</p>



<p>The fires not only contribute to the global carbon emissions but also result in the loss of biodiversity and the degradation of vital ecosystems that are crucial for global climate regulation.</p>



<h3 class="wp-block-heading" id="h-europe-nbsp">Europe&nbsp;</h3>



<p>Europe has not been spared either, with countries like Greece, Portugal, and Spain experiencing deadly wildfires that have been linked to heatwaves and changing precipitation patterns. The Mediterranean region, in particular, is becoming more susceptible to wildfires as temperatures rise and summers become drier.</p>



<h3 class="wp-block-heading" id="h-siberia-fires">Siberia fires</h3>



<p>Russia's Siberia has also seen an increase in fire activity, with massive wildfires engulfing vast areas of forest. The smoke from these fires has reached as far as the United States and Canada, highlighting the global impact of such events. These fires not only release significant amounts of carbon dioxide but also thaw permafrost, releasing methane, a potent greenhouse gas.</p>



<p>The increasing intensity and frequency of fire seasons around the world underscore the urgent need for global action on <a href="https://www.earth.com/news/wildfire-impacts-are-evolving-due-to-climate-change-but-in-what-ways/">climate change</a> and more sustainable land management practices. As temperatures continue to rise and weather patterns become more extreme, the challenge of managing wildfires and mitigating their impacts becomes increasingly daunting.</p>

Intense fire season in Mexico is part of a worldwide trend

<p>In a focused effort to reduce carbon emissions across the U.S. to <a href="https://www.earth.com/news/carbon-pricing-will-help-achieve-net-zero-emissions/" target="_blank" rel="noreferrer noopener">net zero</a>, researchers have united from various Department of Energy national laboratories. </p>



<p>This comprehensive initiative is led by teams at the <a href="https://www.ornl.gov/" target="_blank" rel="noreferrer noopener">Oak Ridge National Laboratory</a> and includes collaboration from Pacific Northwest, Brookhaven, Argonne, Lawrence Berkeley, Ames, and <a href="https://www6.slac.stanford.edu/" target="_blank" rel="noreferrer noopener">SLAC National Accelerator laboratories</a>. Together, the experts are targeting some of the most carbon-intensive sectors of the economy.</p>



<h2 class="wp-block-heading" id="h-recovering-carbon-from-existing-processes">Recovering carbon from existing processes </h2>



<p>Traditionally, efforts to mitigate carbon emissions have focused on capturing or sequestering carbon - known as <a href="https://www.earth.com/news/decarbonizing-worlds-industrial-emissions-possible-with-current-technology/" target="_blank" rel="noreferrer noopener">decarbonization</a>. </p>



<p>However, a new strategy, which the researchers refer to as "defossilization," seeks to minimize the need for extracting new fossil fuels. Instead, it emphasizes recovering and repurposing carbon from existing processes and products. </p>



<p>Stephen Streiffer, the director of ORNL, highlighted the importance of this collaborative effort: "Carbon is a vital part of many of today’s products and processes, and we must be creative in how to address its use in the face of global climate change," said Streiffer.</p>



<p>The proposed "circular economy" would aim to reclaim much of the carbon already present in areas like power generation and materials difficult to recycle, such as biomass, municipal waste, biomethane, carbon dioxide, and plastics. </p>



<p>By reusing carbon where possible, this approach could significantly reduce new emissions, particularly in sectors like transportation and industry, which together account for over 50% of the U.S. <a href="https://www.earth.com/news/reducing-carbon-footprint-urban-farms-and-agriculture/" target="_blank" rel="noreferrer noopener">carbon footprint</a> and are notoriously hard to transition to electricity.</p>



<h2 class="wp-block-heading">Need for defossilization&nbsp;to reduce carbon emissions </h2>



<p>“Electrifying with carbon-free energy sources will be a critical component of decarbonization. However, several segments of our economy, including the manufacturing of chemicals and polymeric materials, will continue to need carbon,” wrote the researchers.</p>



<p>“In addition, segments of our transportation economy will also be difficult to electrify due to the size and weight of the batteries that would be needed, including aviation, long-haul, heavy-duty, and marine transportation. Together, these ‘hard-to-electrify’ segments contribute to ~20% of the overall US greenhouse gas (GHG) emissions.”&nbsp;</p>



<p>“Although efforts are being made to decarbonize parts of these segments, they are unlikely to completely transition from carbon. We can reduce carbon use by increasing efficiency and reducing waste, but that approach alone will not be sufficient to achieve net-zero CO2 emissions.”&nbsp;</p>



<p>“We therefore posit that defossilization, or removing fossil fuels while still using carbon in our economy, is a critical part of achieving net-zero CO2 emissions for difficult-to-electrify sectors.”&nbsp;</p>



<h2 class="wp-block-heading" id="h-translating-discoveries-into-applications">Translating discoveries into applications</h2>



<p>Achieving the ambitious goal of a circular carbon economy requires a rapid advancement in scientific and technological innovation.</p>



<p>Michelle K. Kidder, a distinguished researcher and program manager at ORNL, emphasized the urgency of this task. "Maintaining today’s 15- to 20-year discover-design-develop-deploy cycle will not allow us to slow, stop, or even reverse climate impacts in time to meet aggressive 2030 and 2050 U.S. targets," said Kidder. </p>



<p>"We must instead find new ways to approach fundamental advancements in science and more quickly translate discoveries into applications that can make significant impact on emissions reductions."</p>



<h2 class="wp-block-heading" id="h-overcoming-barriers-to-reduce-carbon-emissions">Overcoming barriers to reduce carbon emissions</h2>



<p>Hundreds of scientists and technical experts from across the national laboratory system are diligently working to overcome longstanding scientific and technological barriers.</p>



<p>ORNL's research, for instance, combines advanced tools such as <a href="https://www.earth.com/news/machine-learning-pinpointed-a-catalyst-for-co2-conversion/" target="_blank" rel="noreferrer noopener">artificial intelligence</a> and machine learning with chemistry to develop new materials. </p>



<p>This effort is bolstered by Frontier, the world’s fastest supercomputer, which supports essential high-performance computations for developing new energy technologies. These include advanced nuclear reactors and potential fusion solutions aimed at reducing carbon emissions.</p>



<p>As these scientific endeavors progress, it is crucial to integrate techno-economic and lifecycle analyses. This approach is vital for identifying the potential environmental and social impacts of new technologies, ensuring that solutions are not only effective but also equitable. </p>



<p>"Even as we look for alternatives to reusing and keeping carbon in play, defossilization must allow equitable and ecological solutions for everyone," explained Kidder. "If we can bring this vision to fruition at the urgent pace needed, we also can reduce <a href="https://www.earth.com/news/global-co2-emissions-expected-to-reach-a-new-high-in-2023/" target="_blank" rel="noreferrer noopener">carbon dioxide</a> and its consequent impact on the environment while ensuring that no community is left behind."</p>



<h2 class="wp-block-heading" id="h-a-collaborative-effort-to-reduce-carbon-emissions">A collaborative effort to reduce carbon emissions</h2>



<p>The roadmap laid out by these researchers offers a promising path toward a sustainable, low-carbon future. By fostering collaboration and accelerating the pace of innovation, there is hope for significantly reducing the U.S. carbon footprint, closing the carbon cycle, and achieving the net-zero emissions necessary to combat climate change effectively. </p>



<p>This ambitious endeavor not only seeks to safeguard the planet but also to ensure a healthier, more sustainable environment for future generations.</p>

<p>Researchers have stumbled upon a phenomenon that could rewrite our understanding of the universe's <a href="https://www.earth.com/news/all-living-things-are-affected-by-gravitational-tides/" target="_blank" rel="noreferrer noopener">gravitational forces</a>. Known as the "cosmic glitch," this discovery highlights anomalies in gravity's behavior on an immense scale, challenging the established norms set by Albert Einstein's theory of general relativity.</p>



<p>For over a century, general relativity has served as the backbone for our understanding of cosmic phenomena, ranging from the dynamics of the Big Bang to the intricacies of black holes. The theory posits that gravity influences not only the three spatial dimensions but also time itself. </p>



<p>Validated through numerous tests and observations, general relativity has been a robust model that physicists and astronomers worldwide rely on.</p>



<h2 class="wp-block-heading" id="h-challenging-einstein-s-legacy">Challenging Einstein's legacy</h2>



<p>However, when applied to the vast scales of <a href="https://www.earth.com/news/titanic-galaxy-cluster-collision-defies-all-current-understanding-of-the-universe/" target="_blank" rel="noreferrer noopener">galaxy clusters</a> and beyond, this model begins to show cracks. </p>



<p>Robin Wen is the project's lead author and a recent graduate in Mathematical Physics from the <a href="https://uwaterloo.ca/" target="_blank" rel="noreferrer noopener">University of Waterloo</a>. "At these colossal distances, general relativity starts to deviate from what we observe. It’s as if gravity’s influence weakens by about one percent when dealing with distances spanning billions of light years," explained Wen.</p>



<p>This observation has puzzled scientists for more than twenty years. Considerable efforts have been made to address these discrepancies and better understand the anomalies observed.</p>



<h2 class="wp-block-heading">Cosmic glitch adds a footnote to general relativity </h2>



<p>Niayesh Afshordi, a professor of Astrophysics at the University of Waterloo and a researcher at the Perimeter Institute, shared insights on the universe's expansion. </p>



<p>"Almost a century ago, astronomers discovered that our universe is expanding,” said Professor Afshordi. "The farther away galaxies are, the faster they are moving, to the point that they seem to be moving at nearly the speed of light, the maximum allowed by Einstein’s theory. Our finding suggests that, on those very scales, Einstein’s theory may also be insufficient.”</p>



<p>Furthermore, the research team has developed a new model that modifies and extends Einstein’s equations to better fit these cosmic observations. </p>



<p>This doesn’t just patch a hole; it enhances our overall understanding of gravity without compromising the successful applications of general relativity that are crucial in other scientific fields.</p>



<p>Robin Wen describes this update as a critical clarification to Einstein’s original theory: "Think of it as a footnote - once you reach a cosmic scale, additional terms and conditions apply."</p>



<h2 class="wp-block-heading">Unraveling the mysteries of gravity</h2>



<p>Using this model that modifies general relativity could be the breakthrough that unlocks further mysteries of the cosmos. "This might just be our first clue in solving a larger cosmic puzzle that spans the vast expanses of space and time," noted Afshordi.</p>



<p>As the scientific community continues to test and refine this new approach to understanding gravity, the anticipation grows. </p>



<p>The implications of the research are far-reaching, potentially leading to new theories that offer a more detailed and comprehensive understanding of the fundamental forces that govern our universe.</p>



<p>This discovery challenges long-held scientific views and is a vibrant example of how scientific inquiry continuously evolves, each solution prompting new questions in the relentless quest for deeper truths.</p>



<h2 class="wp-block-heading">Theory of general relativity</h2>



<p>The theory of general relativity, proposed by Albert Einstein in 1915, describes gravity not as a conventional force, but as a curvature of space-time caused by mass and energy. This marked a profound departure from Newtonian physics, where gravity was considered a force acting at a distance.</p>



<p>Einstein's theory suggests that objects such as planets and stars alter the geometry of space-time around them, and this curvature influences the motion of other objects. This is often visualized as a heavy object placed on a stretched rubber sheet, causing it to deform, and smaller objects rolling towards it due to the deformation.</p>



<p>One of the most famous predictions of general relativity was the bending of light by gravity, which was confirmed during a solar eclipse in 1919, when stars near the Sun appeared slightly displaced from their expected positions. </p>



<p>This phenomenon, known as gravitational lensing, along with the precise precession of Mercury's orbit, and the redshift of light escaping gravitational fields, serve as key evidences for the theory.</p>



<p>The study is published in the <em><em><a href="https://iopscience.iop.org/article/10.1088/1475-7516/2024/03/045">Journal of Cosmology and Astroparticle Physics</a></em></em>.</p>

<p>While the benefits of exercise on overall health are broadly recognized, the intricate biological responses triggered at a cellular level by <a href="https://www.earth.com/news/active-aging-physical-activity-has-a-direct-impact-on-life-quality/" target="_blank" rel="noreferrer noopener">physical activity</a> have only recently been explored in depth. </p>



<p>A landmark study involving an array of scientific experts from various U.S. institutions has significantly advanced our understanding of this complex phenomenon.</p>



<p>The scientists employed a range of sophisticated techniques to investigate the molecular changes that occur across different organs during periods of intense exercise. </p>



<p>The study revealed that physical activity influences a multitude of cellular and molecular mechanisms across all 19 organs analyzed in the rats used for the experiment. </p>



<p>The findings show that the body's adaptation to exercise extends well beyond <a href="https://www.earth.com/news/scientists-discover-molecule-that-helps-grow-stronger-and-bigger-muscles/" target="_blank" rel="noreferrer noopener">muscle growth</a> and <a href="https://www.earth.com/news/the-cardiovascular-benefits-of-exercise-are-unlimited/" target="_blank" rel="noreferrer noopener">cardiovascular health</a>, encompassing significant changes in organs such as the heart, brain, and lungs.</p>



<h2 class="wp-block-heading" id="h-insights-into-the-molecular-benefits-of-exercise">Insights into the molecular benefits of exercise</h2>



<p>The study was a part of an ambitious initiative, the Molecular Transducers of Physical Activity Consortium (MoTrPAC), which began in 2016. </p>



<p>This project brings together researchers from prestigious institutions such as the <a href="https://www.broadinstitute.org/" target="_blank" rel="noreferrer noopener">Broad Institute of MIT and Harvard</a>, <a href="https://www.stanford.edu/" target="_blank" rel="noreferrer noopener">Stanford University</a>, and the <a href="https://www.nih.gov/" target="_blank" rel="noreferrer noopener">National Institutes of Health</a>. </p>



<p>The consortium involved leading scientists who envisioned a comprehensive analysis of exercise's effects at the molecular level. The project was originally conceived of by&nbsp;Steve Carr, senior director of Broad’s Proteomics Platform.</p>



<h2 class="wp-block-heading">Focus of the research</h2>



<p>“Regular exercise provides wide-ranging health benefits, including reduced risks of all-cause mortality, cardiometabolic and neurological diseases, cancer and other pathologies,” wrote the study authors.</p>



<p>“Exercise affects nearly all organ systems in either improving health or reducing disease risk, with beneficial effects resulting from cellular and molecular adaptations within and across many tissues and organ systems.”&nbsp;</p>



<p>“Various ‘omic’ platforms (‘omes’) including transcriptomics, epigenomics, proteomics and metabolomics, have been used to study these events. However, work to date typically covers one or two omes at a single time point, is biased towards one sex, and often focuses on a single tissue, most often skeletal muscle, heart or blood, with few studies considering other tissues.”</p>



<p>“Accordingly, a comprehensive, organism-wide, multi-omic map of the effects of exercise is needed to understand the molecular underpinnings of exercise training-induced adaptations.”&nbsp;</p>



<h2 class="wp-block-heading" id="h-enormously-valuable-resource">Enormously valuable resource </h2>



<p>The expansive study not only scrutinized tissues from various organs but also revealed how these organs contribute to regulating immune response, stress reactions, and even pathways related to chronic conditions like inflammatory liver disease and heart disease.</p>



<p>"It took a village of scientists with distinct scientific backgrounds to generate and integrate the massive amount of high quality data produced,” said Carr.</p>



<p>“This is the first whole-organism map looking at the effects of training in multiple different organs. The resource produced will be enormously valuable, and has already produced many potentially novel biological insights for further exploration.”</p>



<h2 class="wp-block-heading" id="h-molecular-changes-from-exercise">Molecular changes from exercise </h2>



<p>One of the more significant revelations was the discovery of <a href="https://www.earth.com/news/stanford-blood-test-measures-the-molecular-effects-of-exercise/" target="_blank" rel="noreferrer noopener">molecular changes</a> that might explain why the liver becomes less fatty during exercise. Such insights could pave the way for new treatments for conditions like non-alcoholic fatty liver disease.</p>



<p>In addition, the research team hopes their findings can eventually be used to personalize exercise plans based on an individual's health status or to develop therapeutic strategies that mimic the benefits of physical activity for those unable to exercise regularly.</p>



<p>The data from this extensive study have been made available in an <a href="https://motrpac-data.org/" target="_blank" rel="noreferrer noopener">online public repository</a>, allowing other researchers to access and utilize this information for further study. </p>



<h2 class="wp-block-heading" id="h-exercise-impacts-thousands-of-molecules">Exercise impacts thousands of molecules</h2>



<p>The collective effort of the teams involved required significant coordination, as highlighted by Clary Clish, one of the lead researchers. “The amount of coordination that all of the labs involved in this study had to do was phenomenal.” </p>



<p>This meticulous planning allowed for nearly 10,000 assays, resulting in approximately 15 million measurements on blood and solid tissues.</p>



<p>Through these efforts, the researchers have observed that exercise impacts thousands of molecules, with notable changes occurring in the adrenal gland, which plays a crucial role in regulating immunity, metabolism, and blood pressure. </p>



<p>Additionally, the study uncovered sex-specific differences in immune response, providing a nuanced understanding of how exercise affects males and females differently over time. Most immune-signaling molecules unique to females showed changes in levels between one and two weeks of training, while those in males showed differences between four and eight weeks, noted the experts.</p>



<h2 class="wp-block-heading" id="h-foundation-for-future-research">Foundation for future research </h2>



<p>As research continues, these insights offer a promising frontier for enhancing human health through a more refined understanding of the molecular benefits of exercise. </p>



<p>The pioneering study not only furthers our understanding of the biological responses to physical activity but also sets the stage for tailored health interventions that could one day revolutionize personal health and wellness.</p>



<p>"Altogether, this multi-omic resource serves as a broadly useful reference for studying the milieu of molecular changes in endurance training adaptation and provides new opportunities to understand the effects of exercise on health and disease," concluded the researchers.</p>



<p>The study is published in the journal <em><em><a href="https://www.nature.com/articles/s41586-023-06877-w" target="_blank" rel="noreferrer noopener">Nature</a></em></em>.</p>

<p>In recent years, the scientific community has been increasingly interested in the potential benefits of <a href="https://www.earth.com/news/meditation-is-far-better-than-drugs-to-spark-creativity/" target="_blank" rel="noreferrer noopener">meditation</a> and <a href="https://www.earth.com/news/psychedelics-could-help-us-reinvent-ourselves/" target="_blank" rel="noreferrer noopener">psychedelics</a>. A fascinating study has uncovered the synergistic effects of psilocybin and meditation, revealing how this combination can enhance insightfulness and alter brain activity patterns.</p>



<h2 class="wp-block-heading" id="h-unlocking-the-doors-of-perception-during-meditation">Unlocking the doors of perception during meditation</h2>



<p>Berit Singer and a team of researchers from the <a href="https://www.uzh.ch/en.html" target="_blank" rel="noreferrer noopener">University of Zurich</a> and the University Hospital of Psychiatry Zurich have published their findings in the journal <em>Scientific Reports</em>. </p>



<p>The study involved 36 experienced meditators who participated in a 5-day psilocybin-assisted meditation retreat, following a double-blind, randomized, placebo-controlled, parallel-group study design.</p>



<p>The participants completed two fMRI brain imaging sessions, one day before and one day after the retreat. Each scan session consisted of resting-state, focused attention, and open monitoring sequences, with each <a href="https://www.earth.com/news/deep-meditation-transforms-gut-microbes-for-optimal-health/" target="_blank" rel="noreferrer noopener">meditation</a> lasting 7 minutes. </p>



<h2 class="wp-block-heading" id="h-mapping-the-synergy-of-psilocybin-and-meditation">Mapping the synergy of psilocybin and meditation</h2>



<p>The researchers used a novel approach based on the Mapper algorithm from topological data analysis to generate subject-specific maps for two groups (<a href="https://www.earth.com/news/how-psilocybin-mushrooms-got-their-magic/" target="_blank" rel="noreferrer noopener">psilocybin</a> vs. placebo, 18 subjects/group) of experienced meditators.</p>



<p>The study revealed several intriguing findings:</p>



<ul>
<li>Psilocybin-induced positive derealization, when accompanied by enhanced open-monitoring meditation, was linked to the optimal transport (OT) distance between open-monitoring and resting state.</li>
</ul>



<ul>
<li>Enhanced meta-awareness through <a href="https://www.earth.com/news/loving-kindness-meditation-increases-positive-emotions-and-happiness/" target="_blank" rel="noreferrer noopener">meditation practice</a> in experienced meditators, combined with potential psilocybin-induced positive alterations in perception, mediate insightfulness.</li>
</ul>



<ul>
<li>Psilocybin alters the perception of the external world, presumably by increasing informational richness, which is reflected by increased OT distances between open-monitoring and resting state post-retreat.</li>

<p>Singer, one of the study's lead authors, expressed her fascination with the application of pure mathematics, especially topology, to extract important information from latent structures in data. </p>



<p>Speaking to PsyPost, she expressed her surprise by the common structure revealed among the subject-specific Mapper graphs, despite their initial apparent differences.</p>

<p>This study provides a novel perspective on the potential synergistic effects between mindfulness practices and psilocybin. It suggests that the combination of enhanced meta-awareness through <a href="https://www.earth.com/news/meditation-may-lead-to-better-focus-sleep-and-sex-life/" target="_blank" rel="noreferrer noopener">meditation</a> and psilocybin-induced positive alterations in perception can foster insightfulness.</p>



<p>The findings also highlight the importance of understanding the neurophysiology of meditation and psychedelics beyond the conventional measures of functional connectivity, resting-state networks, and signal variability. </p>



<p>By applying topological data analysis, the researchers were able to uncover organizational principles and characteristics of whole-brain activity patterns during different styles of meditation and psilocybin-induced alterations.</p>



<h2 class="wp-block-heading" id="h-positive-effects-of-psilocybin-on-the-brain">Positive effects of psilocybin on the brain</h2>



<p>As researchers continue to investigate the <a href="https://www.earth.com/news/study-offers-new-explanation-for-how-psychedelic-drugs-work/" target="_blank" rel="noreferrer noopener">effects of psilocybin</a> on the brain, they have uncovered several positive outcomes that may revolutionize the way we approach mental health treatment.</p>



<h3 class="wp-block-heading">Psilocybin promotes neuroplasticity with and without meditation</h3>



<p>One of the most promising effects of psilocybin on the brain is its ability to promote neuroplasticity and enhance neural connectivity. </p>



<p>Studies have shown that psilocybin can facilitate the growth of new neural connections and increase the flexibility of existing ones. </p>



<p>This heightened neuroplasticity allows the brain to adapt and reorganize itself more efficiently, which may contribute to the long-lasting <a href="https://www.earth.com/news/australia-is-the-first-country-to-legalize-psychedelics-for-mental-health-treatment/" target="_blank" rel="noreferrer noopener">positive changes</a> observed in individuals who have undergone psilocybin-assisted therapy.</p>



<h3 class="wp-block-heading">Reduction of anxiety and depression</h3>



<p>Psilocybin has demonstrated remarkable potential in alleviating symptoms of <a href="https://www.earth.com/news/psilocybin-microdosing-may-improve-mental-health-by-boosting-stress-resilience/" target="_blank" rel="noreferrer noopener">anxiety and depression</a>, even in cases where conventional treatments have failed. </p>



<p>Research suggests that psilocybin can modulate the activity of serotonin receptors in the brain, leading to a reduction in negative thought patterns and an increase in positive emotions. </p>



<p>Moreover, the profound mystical experiences often associated with psilocybin use may help individuals gain new perspectives on their lives and develop a greater sense of meaning and purpose.</p>



<h3 class="wp-block-heading">Increased openness and creativity</h3>



<p>Studies have found that psilocybin can enhance openness, a personality trait characterized by curiosity, imagination, and a willingness to embrace new experiences. </p>



<p>Increased openness has been linked to improved creative thinking, problem-solving abilities, and overall psychological well-being. </p>



<p>By fostering a more open and flexible mindset, psilocybin may help individuals break free from rigid thought patterns and explore novel ideas and solutions, particularly during meditation practice.</p>



<h2 class="wp-block-heading" id="h-psilocybin-and-the-future-of-psychedelic-meditation">Psilocybin and the future of psychedelic meditation</h2>



<p>In summary, the study by Singer and her colleagues has opened up new avenues for exploring the potential benefits of combining <a href="https://www.earth.com/news/meditation-breathing-brain-health/" target="_blank" rel="noreferrer noopener">meditation</a> and psychedelics. </p>



<p>As Singer noted, "These findings provide a novel perspective on meditation and psychedelics that may reveal potential novel brain markers for positive synergistic effects between mindfulness practices and <a href="https://www.earth.com/news/synthetic-psilocybin-less-effective-therapy-than-natural-mushroom-extract/" target="_blank" rel="noreferrer noopener">psilocybin</a>."</p>



<p>By applying novel techniques like topological data analysis, the researchers have uncovered intriguing synergistic effects between psilocybin and meditation, revealing how this combination can enhance insightfulness, alter brain activity patterns, and potentially lead to new therapeutic approaches for mental health and well-being. </p>



<p>As the scientific community continues to investigate the neurophysiology of meditation and psychedelics, this study serves as a catalyst for further research, promising to deepen our understanding of consciousness and the mechanisms underlying the positive effects of these practices.</p>

Psilocybin deeply enhances meditation insights

In recent years, the scientific community has been increasingly interested...

<p>It's a common concern among parents: the impact of social media on the <a href="https://www.earth.com/news/teens-losing-sleep-smartphones/" target="_blank" rel="noreferrer noopener">lives</a> of children and teens. Many worry that these digital interactions might replace or damage real-life social skills and connections.</p>



<p>However, recent findings suggest that these fears may be unfounded. In fact, kids who are active on social media are also actively engaging in social activities offline.</p>



<h2 class="wp-block-heading" id="h-more-offline-activity-among-social-media-users">More offline activity among social media users</h2>



<p>A recent study led by Silje Steinsbekk, a professor in the Department of Psychology at <a href="https://www.ntnu.edu/" target="_blank" rel="noreferrer noopener">NTNU</a>, challenges the prevailing notions about social media use among youth. </p>



<p>"On the contrary, we find that people who use social media a lot spend more time with friends offline," said Professor Steinsbekk.</p>



<p>This observation stems from a comprehensive analysis carried out as part of the Trondheim Early Secure Study, which tracked around 800 young individuals over key developmental ages at 10, 12, 14, 16, and 18 years old.</p>



<h2 class="wp-block-heading">Significance of the study</h2>



<p>“Throughout childhood and adolescence, social skills develop in interaction with the social environment, including parents, family, and friends. While not long ago, such interactions solely took place face-to-face, teens now spend an average of almost 4 h daily on social media like TikTok, Instagram, and Snapchat,” wrote the study authors.&nbsp;</p>



<p>“However, questions remain as to how social media use affects the development of social skills, which is important to know given the beneficial outcomes of such skills and the drawbacks of lacking them in terms of mental health, academic achievement, coping, and self-esteem.”</p>



<p>“On the one hand, it has been argued that social media interactions provide fewer affordances to practice social skills, thus negatively impacting the development of such skills. On the other hand, it has been hypothesized that social media may constitute an additional arena for social interaction, potentially promoting social skills via more opportunities to interact.”&nbsp;</p>



<p>“This study is the first to examine the validity of these contrasting hypotheses. In addition, it investigates whether increased.”</p>



<h2 class="wp-block-heading" id="h-social-media-enhances-not-hinders-social-engagement">Social media enhances, not hinders, social engagement</h2>



<p>The research team delved into critical a question: Does more time on social media affect children’s <a href="https://www.earth.com/video/screen-time-does-not-inhibit-social-skills-among-kids/" target="_blank" rel="noreferrer noopener">social skills</a> and their real-world interactions with peers? </p>



<p>The results were conclusive. "Social media is a new arena for social interaction. We found no evidence to support the notion that social media hampers the development of <a href="https://www.earth.com/news/video-games-social-skills/" target="_blank" rel="noreferrer noopener">social skills</a>," said Professor Steinsbekk.</p>



<p>The study further demonstrated that children who are frequently active online often spend several evenings a week socializing with their friends in person.</p>



<h2 class="wp-block-heading" id="h-complex-aspects-of-social-media-use">Complex aspects of social media use </h2>



<p>While the study provides reassurance, it also highlights the more complex aspects of social media use. The research indicated that children with <a href="https://www.earth.com/news/breakthrough-discovery-social-anxiety-can-be-targeted-in-the-gut/" target="_blank" rel="noreferrer noopener">social anxiety</a> might be especially susceptible to the adverse effects of extensive use.</p>



<p>"This correlation was weak, so we are reluctant to draw strong conclusions until more research has been done," said Professor Steinsbekk.</p>



<p>The research serves as an important reminder of the complexity of how social media interacts with <a href="https://www.earth.com/news/social-media-break-can-significantly-improve-mental-health/" target="_blank" rel="noreferrer noopener">mental health</a>.</p>



<p>Interestingly, the study also pointed to potential benefits of social media, such as increased closeness in friendships, the formation of new friendships, and the strengthening of existing ones. </p>



<p>These positive aspects could explain why more socially active children also engage more offline.</p>



<h2 class="wp-block-heading" id="h-rapidly-evolving-nature-of-technology">Rapidly evolving nature of technology </h2>



<p>The study concludes on a cautiously optimistic note. "We hope the findings can help reduce parents’ concerns somewhat," said Professor Silje Steinsbekk.</p>



<p>However, she also emphasizes the rapidly evolving nature of technology and its challenges for research. This underscores the need for ongoing study to keep pace with technological advances and their implications for young users.</p>



<p>The insights from this study are critical not just for understanding the social dynamics of today's youth but also for guiding future research and policy. </p>



<p>"Social media has created a new social landscape for adolescents. Knowledge is needed on how this landscape shapes adolescents’ social skills and time spent with friends, as these outcomes are important to mental health and psychosocial functioning," wrote the researchers.</p>



<p>As we navigate this ever-changing digital landscape, it is crucial to stay informed about the real effects of our online behaviors on offline relationships. While the digital age poses new challenges, it also offers new avenues for connection and social growth.</p>



<p>The study is published in the journal <a href="https://www.sciencedirect.com/science/article/pii/S0747563224001031?via%3Dihub" target="_blank" rel="noreferrer noopener"><em><em>Computers in Human Behavior</em></em>.</a></p>

<p>Researchers have uncovered a fundamental connection between <a href="https://www.earth.com/news/quantum-entanglement-discovery-is-a-revolutionary-step-forward/" target="_blank" rel="noreferrer noopener">quantum entanglement</a>, entropy, and the laws of thermodynamics. This discovery sheds new light on the behavior of quantum systems and could have far-reaching implications for the development of quantum technologies.</p>



<h2 class="wp-block-heading" id="h-when-quantum-entanglement-met-the-rule-of-entropy">When quantum entanglement met the rule of entropy</h2>



<p>Bartosz Regula from the <a href="https://www.riken.jp/en/research/labs/rqc/" target="_blank" rel="noreferrer noopener">RIKEN</a> Center for Quantum Computing and Ludovico Lami from the <a href="https://www.uva.nl/en" target="_blank" rel="noreferrer noopener">University of Amsterdam</a> have made a significant breakthrough in understanding the nature of quantum entanglement. </p>



<p>Through probabilistic calculations, they have shown that there is indeed a rule of entropy governing this enigmatic phenomenon.</p>



<p>"Our findings mark significant progress in understanding the basic properties of entanglement, revealing fundamental connections between entanglement and thermodynamics, and crucially, providing a major simplification in the understanding of entanglement conversion processes," said Regula.</p>



<h2 class="wp-block-heading" id="h-second-law-of-thermodynamics-and-quantum-systems">Second law of thermodynamics and quantum systems</h2>



<p>The second law of thermodynamics, which states that a system can never move to a state with lower entropy, is one of the most fundamental <a href="https://www.earth.com/news/radical-new-theory-finally-unites-gravity-spacetime-and-the-quantum-realm/" target="_blank" rel="noreferrer noopener">laws of nature</a>. It creates the "arrow of time" and encapsulates the dynamics of even the most complex physical systems.</p>



<p>However, as we delve deeper into the quantum world, it becomes increasingly important to understand how this law applies to quantum systems. </p>



<p>Quantum entanglement, a key resource that underlies much of the power of future <a href="https://www.earth.com/news/quantum-computer-can-instantly-execute-a-task-that-would-normally-take-47-years/" target="_blank" rel="noreferrer noopener">quantum computers</a>, has been the focus of research in quantum information science for decades. Despite its significance, little is currently understood about the optimal ways to make effective use of it.</p>



<h2 class="wp-block-heading" id="h-probabilistic-transformations-and-reversible-entanglements">Probabilistic transformations and reversible entanglements</h2>



<p>The difficulty in establishing a "second law" for quantum entanglement lies in the fact that entanglement transformations must be made reversible, just like work and heat can be interconverted in thermodynamics. </p>



<p>However, ensuring the reversibility of entanglement is much more challenging than in the case of thermodynamic transformations.</p>



<p>Previous attempts at establishing a reversible theory of <a href="https://www.earth.com/news/unraveling-gravity-quantum-nature-entanglement-mechanics/" target="_blank" rel="noreferrer noopener">entanglement</a> have failed, and it was even suspected that entanglement might be irreversible. This made the quest for a "second law" of entanglement seem like an impossible one.</p>



<h2 class="wp-block-heading" id="h-key-to-reversible-quantum-connections">Key to reversible quantum connections</h2>



<p>Regula and Lami solve this long-standing conjecture by using <a href="https://www.earth.com/news/quantum-ping-pong-game-played-by-two-atoms-controlling-photons/" target="_blank" rel="noreferrer noopener">probabilistic entanglement</a> transformations. These transformations are only guaranteed to be successful some of the time, but in return, they provide an increased power in converting quantum systems.</p>



<p>Under such processes, the authors show that it is indeed possible to establish a reversible framework for entanglement manipulation. </p>



<p>They identify a setting in which a unique entropy of entanglement emerges, and all entanglement transformations are governed by a single quantity. </p>



<p>The methods they used could be applied more broadly, showing similar reversibility properties for more general <a href="https://www.earth.com/news/full-chemical-complexity-of-quantum-decoherence-finally-revealed/" target="_blank" rel="noreferrer noopener">quantum resources</a> as well.</p>



<p>"This not only has immediate and direct applications in the foundations of quantum theory, but it will also help with understanding the ultimate limitations on our ability to efficiently manipulate entanglement in practice," Regula explained.</p>



<h2 class="wp-block-heading" id="h-entanglement-entropy-as-a-new-frontier">Entanglement entropy as a new frontier</h2>



<p>While this discovery marks a significant milestone in understanding the basic properties of <a href="https://www.earth.com/news/secure-quantum-communication-one-step-closer-reality/" target="_blank" rel="noreferrer noopener">entanglement</a>, there is still much to be explored. </p>



<p>Regula notes that even stronger forms of reversibility have been conjectured, and there is hope that entanglement can be made reversible under weaker assumptions than those made in their work, without relying on probabilistic transformations.</p>



<p>"Understanding the precise requirements for reversibility to hold thus remains a fascinating open problem," Regula concluded.</p>



<h2 class="wp-block-heading" id="h-quantum-leap-into-the-future">Quantum leap into the future</h2>



<p>In summary, the important discovery by Bartosz Regula and Ludovico Lami marks a significant milestone in our understanding of quantum entanglement and its relationship to the fundamental laws of thermodynamics. </p>



<p>Their work provides a new framework for analyzing and manipulating entanglement while opening exciting avenues for future research. </p>



<p>As we continue to explore the quantum world and harness its potential for revolutionary technologies, this finding will undoubtedly serve as a guiding light, illuminating the path towards a deeper understanding of the complex and fascinating phenomena that lie at the heart of quantum mechanics.</p>

Quantum entanglement does, in fact, follow a rule of entropy

Researchers have uncovered a fundamental connection between quantum entanglement, entropy,...

<p><a href="https://www.earth.com/news/seagulls-birds-more-intelligent-than-believed/" target="_blank" rel="noreferrer noopener">Seagull</a> species with larger brains are more likely to choose cliffs for nesting and may also be better adapted to urban environments, such as the rooftops of buildings, according to a recent study led by the <a href="https://www.exeter.ac.uk/" target="_blank" rel="noreferrer noopener">University of Exeter</a>.</p>



<p>Exploring the link between brain size, wing shape, nesting habits, and <a href="https://www.earth.com/news/urban-lizards-show-physical-and-genetic-adaptations/" target="_blank" rel="noreferrer noopener">urban adaptation</a>, the experts discovered that over half of cliff-nesting gull species are nesting in urban settings, a significant contrast to the 11% of non-cliff-nesting species doing the same. </p>



<h2 class="wp-block-heading" id="h-seagulls-nesting-in-challenging-environments">Seagulls nesting in challenging environments</h2>



<p>The research highlights a correlation between larger <a href="https://www.earth.com/news/seagulls-birds-more-intelligent-than-believed/" target="_blank" rel="noreferrer noopener">brain sizes</a> and the ability to adapt to more challenging nesting environments.</p>



<p>“Many people will be familiar with gulls nesting and foraging in urban areas,” said lead author Madeleine Goumas, a former postdoctoral research associate at Exeter's Center for Ecology and Conservation. “It's not something you might expect from a seabird, so we wanted to try to understand why they do it."</p>



<h2 class="wp-block-heading" id="h-seagulls-nesting-in-urban-settings-nbsp">Seagulls nesting in urban settings&nbsp;</h2>



<p>The research involved a comprehensive review of existing studies, analyzing urban breeding and foraging behaviors among different seagull species.&nbsp;</p>



<p>The findings revealed that 13 of the 50 gull species have adapted to urban environments for breeding, with the same number identified as urban foragers; nine species engage in both behaviors.</p>



<p>The data showed that 53% of cliff-nesting gull species were found to nest in urban areas, compared to only 11% of non-cliff-nesters.&nbsp;</p>



<h2 class="wp-block-heading" id="h-seagulls-with-larger-brains">Seagulls with larger brains</h2>



<p>“We found that gull species with larger brains are more likely to be cliff-nesters, and cliff-nesting species are more likely to breed in urban areas,” said senior author Neeltje Boogert, a senior lecturer in biosciences at Exeter.</p>



<p>“It's also not a fixed behavior in most gulls. While non-cliff-nesting species nest exclusively on the ground, most cliff-nesting species nest either on cliffs or the ground.”</p>



<p>“This suggests that bigger brains enable these gull species to be flexible with regard to where they choose to nest, and this allows them to use unconventional sites, like buildings, for raising their young.”</p>



<p>Regarding <a href="https://www.earth.com/news/fish-foraging-behavior-changing-climate-warming-waters/" target="_blank" rel="noreferrer noopener">foraging behavior</a>, the study concluded that neither brain size nor wing shape, which influences maneuverability, were definitive factors in predicting urban foraging activities.</p>



<h2 class="wp-block-heading" id="h-implications-for-conservation">Implications for conservation</h2>



<p>The scientists also examined the conservation status of these seagulls, discovering that those with stable or growing populations were more likely to utilize urban habitats compared to those in decline. Among the ten gull species listed as Threatened or Near Threatened, only the black-legged kittiwake was observed using urban settings.</p>



<p>“Whether or not species use urban areas has important implications for conservation,” Boogert explained. “If we can understand the factors that allow animals to use urban areas, we can better understand how to help those that aren't faring so well.”</p>



<p>“Urbanization is a major problem for a lot of animals. It looks like some gull species have managed to overcome some of the challenges that prevent other animals from using urban areas, but we need more long-term studies as well as comparative studies on other taxa to fully understand the impacts of urban living,” Goumas added.</p>



<p>This research is part of a broader investigation into gull behavior, which includes studies on how gulls prefer food handled by humans and how maintaining eye contact can deter them from stealing food.</p>



<h2 class="wp-block-heading" id="h-more-about-seagull-nesting-behaviors-nbsp">More about seagull nesting behaviors&nbsp;</h2>



<p>Seagulls are fascinating creatures, particularly when it comes to their nesting behaviors, which exhibit some unique strategies adapted to their environments.&nbsp;</p>



<p>Generally, seagulls are colonial nesters, meaning they prefer to nest in large groups, which offers protection against predators. The location of these colonies can vary widely, including isolated, flat roofs of buildings, sandy beaches, or rocky cliffs near the sea.</p>



<h3 class="wp-block-heading" id="h-nesting-strategies">Nesting strategies</h3>



<p>A typical nesting site is chosen for its safety from ground predators and its proximity to food sources. Seagulls are quite adaptable and may adjust their nesting strategies based on their environment. For instance, urban gulls might nest on man-made structures, while those in more natural settings will choose spots that offer natural protection.</p>



<p>When building their nests, seagulls use a variety of materials, including sticks, seaweed, and feathers, constructing them to cradle their eggs securely. A seagull's nest is relatively simple, not much more than a scrape on the ground or a slight mound to keep the eggs in place.</p>



<h3 class="wp-block-heading" id="h-mating-pairs-nbsp">Mating pairs&nbsp;</h3>



<p>Seagulls are also particularly defensive of their nesting sites. Both the male and female participate in nest building and the care of the young. The mating pair typically forms a bond that can last many years and is reinforced each season through ritual behaviors and mutual care.</p>



<h3 class="wp-block-heading" id="h-breeding-season">Breeding season</h3>



<p>The <a href="https://www.earth.com/news/extreme-snowstorms-impact-breeding-success-of-petrels/" target="_blank" rel="noreferrer noopener">breeding</a> season is a noisy time in a gull colony, filled with calls and aggressive interactions between neighbors and intruders. Eggs are generally laid from late March through May, with the specifics depending on the location and species. The incubation period for seagull eggs lasts about three to five weeks, and both parents share the duty of warming the eggs.</p>



<p>Once hatched, the chicks are semi-precocial, meaning they are relatively mature and mobile from the moment of birth, yet remain dependent on their parents for food and protection. The young are usually ready to fly and leave the nest within six weeks after hatching, though parental care may continue until they are fully capable of independent survival.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.</p>



<p>"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.</p>



<p>"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."</p>

<p>Today's <strong>Video of the Day</strong> from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.</p>



<p>"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.</p>



<p>To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;</p>



<p>"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.</p>



<p>"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."</p>

High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."</p>

<p>Today's <strong>Video of the Day</strong> from the <a href="https://www.acs.org/">American Chemical Society</a> describes a new self-powered nanosensor that can instantly detect mercury contamination with the tap of a finger.&nbsp;</p>



<p>The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;</p>



<p>Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.</p>

<p>Today’s <strong>Video of the Day</strong> from the <a href="https://www.esa.int/">European Space Agency</a> features Kainji Lake, a reservoir on the Niger River.</p>



<p>In 1968, Kainji Lake was created by the construction of the Kainji Dam. The Niger River, the third longest in Africa, enters the lake in the north.&nbsp;</p>



<p>According to <a href="https://www.earth.com/news/rivers-in-the-american-west-are-a-lifesaving-resource-for-birds/">ESA</a>, the creation of the lake submerged Foge Island and the town of Bussa and permanently flooded other riverine settlements, leaving around 50,000 people displaced.&nbsp;</p>



<p>Large parts of Foge Island are temporarily exposed during low water tides, and the land is often used by migrating fishermen. Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. </p>



<p>Wild mammals occur at relatively low densities due to illegal hunting. Lake Kainji has suffered a dramatic decline as a fishery due to the high numbers of artisanal and subsistence fisherfolk using the lake. It has been suggested that a period of closure, together with controlled fishing rights may help improve fish stocks.</p>



<p>Kainji Lake National Park is the oldest of its kind in Nigeria. The park contains three distinct areas: a part of the Kainji Lake, the Borgu Game Reserve to the west of the lake, and the Zugurma Game Reserve to the southeast. The park is home to around 65 mammal species, 350 bird species, and 30 species of reptiles and amphibians. </p>

<p>Today’s <strong>Video of the Day</strong> from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.</p>



<p>“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. </p>



<p>The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.</p>



<p>“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;</p>



<p>“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”</p>



<p>The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;</p>



<p>The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.</p>
