<p>As the Northern Hemisphere ushers in the warmth of spring, East Asia grapples with a less welcome sign of the season: colossal <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>. </p>



<h2 class="wp-block-heading" id="h-desert-dust-reaches-the-korean-peninsula-nbsp">Desert dust reaches the Korean Peninsula&nbsp;</h2>



<p>Originating from the expansive Gobi and Taklamakan deserts, these dust plumes journey across China, reaching as far as the Korean Peninsula and southern Japan, reshaping the springtime landscape both literally and metaphorically.</p>



<p>The phenomenon was starkly illustrated on April 25, 2024, when NASA's Aqua satellite, equipped with the MODIS (Moderate Resolution Imaging Spectroradiometer) sensor, captured a dramatic image of a massive dust wall traversing the Korean Peninsula.&nbsp;</p>



<h2 class="wp-block-heading" id="h-primary-source-of-the-dust-over-korea">Primary source of the dust over Korea</h2>



<p>The imagery from the preceding day, courtesy of South Korea’s GEO-KOMPSAT-2A satellite and NASA’s Terra and Aqua satellites, pinpointed the Gobi Desert in Inner Mongolia as the primary source of this <a href="https://www.earth.com/news/atmospheric-dust-plays-surprisingly-crucial-role-in-stabilizing-ocean-ecosystems/" target="_blank" rel="noreferrer noopener">dust</a>. </p>



<p>Compounding the environmental spectacle, a phytoplankton bloom, partially veiled by the dust, was visible to the east of the Korean Peninsula, presenting a complex interaction of earth and ocean.</p>



<h2 class="wp-block-heading" id="h-where-does-the-dust-go">Where does the dust go?</h2>



<p>This seasonal dust does not simply settle locally but sometimes ascends high into the atmosphere, occasionally soaring above cloud level. This elevation enables the particles to traverse vast distances, including crossing the Pacific Ocean to North America.&nbsp;</p>



<p>However, not all the <a href="https://www.earth.com/news/sahara-desert-dust-storms-carry-harmful-bacteria-and-fungi-around-the-globe/" target="_blank" rel="noreferrer noopener">dust</a> achieves such heights; much remains nearer to the ground, significantly deteriorating air quality in one of the planet's most densely populated areas.</p>



<p>The health implications of these dust storms are profound. Breathing in the fine particulate matter, particularly PM2.5, is linked to severe cardiovascular and respiratory issues.</p>



<h2 class="wp-block-heading" id="h-dust-storms-in-east-asia-nbsp">Dust storms in East Asia&nbsp;</h2>



<p>Dust storms in East Asia are commonly known as yellow dust, Asian dust, yellow wind, or China dust storms. The storms are typically most frequent in spring and can extend into early summer. They arise when strong winds lift large amounts of sand and dust from deserts in China and Mongolia, then transport these particles across the region.</p>



<p>The key factors contributing to these dust storms include:</p>



<h3 class="wp-block-heading" id="h-natural-conditions">Natural conditions</h3>



<p>The Gobi Desert and other arid regions in China and Mongolia are the primary sources of the dust. The natural aridness and loose soil make these areas prone to dust lift-off under certain meteorological conditions.</p>



<h3 class="wp-block-heading" id="h-meteorological-factors">Meteorological factors</h3>



<p>Spring brings about changes in temperature and pressure, which can result in strong winds. These winds are capable of carrying dust over long distances. The occurrence and intensity of these storms are closely linked to weather patterns such as the strength of the Siberian High and the East Asian jet stream.</p>



<h3 class="wp-block-heading" id="h-human-impact">Human impact</h3>



<p>Overgrazing, <a href="https://www.earth.com/news/global-deforestation-crisis-how-can-we-stop-massive-forest-losses/" target="_blank" rel="noreferrer noopener">deforestation</a>, and land degradation have exacerbated the frequency and intensity of dust storms. Human activities have led to increased desertification, which contributes to the severity of the storms.</p>



<p>Efforts to combat these dust storms have included afforestation projects, such as planting trees to stabilize the soil, and sustainable land management practices aimed at reducing <a href="https://www.earth.com/news/oases-grow-by-human-effort-but-face-threats-from-desertification/" target="_blank" rel="noreferrer noopener">desertification</a>. Regional cooperation among affected countries has also been essential in monitoring and managing the impacts of these dust events.</p>



<h2 class="wp-block-heading" id="h-more-about-the-korean-peninsula-nbsp">More about the Korean Peninsula&nbsp;</h2>



<p>The Korean Peninsula extends southward from the eastern end of the Asian continent and is bordered by the Sea of Japan (East Sea) to the east, the Yellow Sea to the west, and the Korea Strait connecting to the East China Sea to the south. It is divided into two distinct sovereign states: North Korea and South Korea.</p>



<h3 class="wp-block-heading" id="h-historical-context">Historical context</h3>



<p>Historically, the Korean Peninsula was unified for much of its history under various kingdoms such as Goguryeo, Silla, Baekje, and later the Goryeo and Joseon dynasties. The last, the Joseon Dynasty, lasted until the early 20th century.&nbsp;</p>



<p>Following the end of World War II in 1945, the peninsula was divided into North and South Korea in 1948 amid growing Cold War tensions, leading to the Korean War from 1950 to 1953, which ended with an armistice but no formal peace treaty.</p>



<h3 class="wp-block-heading" id="h-cultural-aspects-of-north-and-south-korea">Cultural aspects of North and South Korea </h3>



<p>Korean culture is distinguished by its language, customs, and cuisine. Both North and South Korea share cultural foundations based on their Confucian heritage, which influences social etiquette, family relations, and personal conduct. However, decades of separation have fostered distinct societal developments in each country.</p>



<h3 class="wp-block-heading" id="h-economy">Economy</h3>



<p>North Korea has a largely isolated economy with limited engagement with the international community, heavily reliant on its natural resources and some agricultural output.</p>



<p>South Korea boasts the 10th largest economy in the world (as of 2021), with strong industries in electronics, telecommunications, automobile production, shipbuilding, and chemical manufacturing. It is also a leader in technological innovation and infrastructure.</p>



<h3 class="wp-block-heading" id="h-current-issues">Current issues</h3>



<p>The Korean Peninsula continues to face challenges, including security concerns due to North Korea's nuclear ambitions and the ongoing military tensions between the North and South. </p>



<p>Additionally, both countries deal with internal and external economic pressures, global market dynamics, and cultural exportation impacting global perceptions and economic health.</p>



<p>The Korean Peninsula presents a unique study in contrasts, with profound historical ties and shared cultural elements, yet marked differences in political, economic, and social systems.</p>

<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 picturesque wetlands of Spain's Doñana National Park, This vital ecosystem, located in the Andalusia region, has received some long-awaited rainfall after enduring years of severe <a href="https://www.earth.com/news/climate-change-has-made-droughts-20-times-more-likely/" target="_blank" rel="noreferrer noopener">drought</a> conditions. </p>



<p>A significant increase in rainfall in March 2024 brought temporary relief to this UNESCO World Heritage Site and Biosphere Reserve, known for its rich biodiversity and critical role as a Ramsar Wetland of International Importance.</p>



<h2 class="wp-block-heading" id="h-a-decade-of-drought-in-donana-national-park">A decade of drought in Doñana National Park</h2>



<p>For over a decade, Doñana National Park has faced below-average rainfall levels, with the situation worsening significantly in the past three years. These years have recorded some of the lowest annual precipitation totals, compounded by unusually high temperatures across the country.&nbsp;</p>



<p>The effects of <a href="https://www.earth.com/news/drought-to-downpour-climate-change-triggers-extreme-weather-shifts/" target="_blank" rel="noreferrer noopener">climate change</a> were starkly visible in January 2024, which was noted as Spain's warmest January since records began, with temperatures averaging 2.4 degrees Celsius higher than normal.</p>



<p>The first quarter of 2024 continued this trend, potentially marking it as the warmest first quarter since 1961. The prolonged <a href="https://www.earth.com/news/global-drought-crisis-un-warns-of-unprecedented-emergency/" target="_blank" rel="noreferrer noopener">drought</a> has had a devastating impact on the park’s ecosystem, drying up <a href="https://www.earth.com/news/nearly-all-of-the-worlds-salt-marshes-may-be-underwater-by-2100/" target="_blank" rel="noreferrer noopener">marshes</a> and affecting both flora and fauna.</p>



<h2 class="wp-block-heading" id="h-welcome-change-in-the-weather">Welcome change in the weather</h2>



<p>The heavy rains that arrived in late March 2024 have momentarily brought some relief to the region. Satellite images acquired by the OLI on Landsat 8 and the OLI-2 on Landsat 9 showed significant changes in the landscape by April 9, 2024.&nbsp;</p>



<p>The featured image shows that marshes have been replenished and ponds have been temporarily filled, contrasting sharply with the desolate conditions observed just a year earlier.</p>



<p>A weather station in the park recorded 145 millimeters of rainfall in March 2024, making it the second-wettest March on record. Since the start of the water year in September 2023, the area has received over 400 millimeters of rainfall, surpassing the totals of each of the last three full water years. Despite this increase, the precipitation still falls short of the historical yearly average of more than 500 millimeters.</p>



<h2 class="wp-block-heading" id="h-ecological-responses-and-challenges">Ecological responses and challenges</h2>



<p>The western part of the park is home to thousands of small, shallow pools known as Mediterranean temporary ponds, which naturally experience cycles of flooding and drying. Following the recent rains, several of the largest ponds flooded, as did marsh areas farther inland, though some regions remained dry.</p>



<p>The Doñana Biological Station reported that this influx of water led to a resurgence of vegetation beneficial to breeding waterfowl such as coots, grebes, and herons.&nbsp;</p>



<p>However, despite these positive signs, the challenges remain significant. Development pressures from agricultural fields and an adjacent resort town continue to strain the local aquifer, exacerbating the water scarcity and impacting the wetland's ecological balance.</p>



<h2 class="wp-block-heading" id="h-long-term-concerns-for-donana-national-park">Long-term concerns for Doñana National Park</h2>



<p>Javier Bustamante, a researcher at the Doñana Biological Station, emphasized that while the rainfall has eased some of the immediate drought-related issues, it does not address the deeper problem of groundwater overexploitation.&nbsp;</p>



<p>"The rains have partially alleviated the most immediate drought problems, but they do not solve the invisible problem of groundwater overexploitation," Bustamante stated, highlighting the complex nature of the challenges facing Doñana.</p>



<p>The overall effect of the rainfall will become clearer in the coming months, but experts caution that the changes observed might not signify long-term relief. Conservation efforts continue to focus on managing external pressures and restoring the ecological balance to preserve Doñana National Park for future generations.</p>



<h2 class="wp-block-heading" id="h-more-about-donana-national-park">More about Doñana National Park</h2>



<p>Doñana National Park is one of Europe's most important and diverse natural reserves. This vast park stretches across parts of the provinces of Huelva, Seville, and Cádiz. It was established as a national park in 1969 and covers an area of approximately 543 square kilometers.</p>



<p>The park is celebrated for its extraordinary biodiversity. It serves as a critical stopover, breeding, and wintering site for thousands of European and African migratory birds.&nbsp;</p>



<p>Doñana's complex ecosystem includes <a href="https://www.earth.com/news/coastal-wetlands-are-inching-closer-to-extinction-as-the-world-heats-up/" target="_blank" rel="noreferrer noopener">marshlands</a>, shallow streams, and sand dunes, providing habitat for a wide variety of plant and animal species. Among its notable inhabitants are the Iberian lynx and the Spanish imperial eagle, both of which are endangered species.</p>



<p>Doñana also has a rich cultural heritage; it has been influenced by various civilizations throughout history, including the Romans and Moors. This history is reflected in the archaeological sites found within its boundaries, including the remains of the town of La Algaida.</p>

Doñana National Park gets temporary relief from drought

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 the Ruki River in the Democratic Republic of the Congo (DRC). It is a tributary of the Congo River, one of the largest <a href="https://www.earth.com/news/warmer-rivers-keep-antimicrobial-resistant-genes-at-bay/">rivers</a> in the world by discharge and depth. </p>



<p>The Ruki River, previously known as the Busira, merges with the Momboyo River near the town of Basankusu to become the Lulonga River, which eventually flows into the Congo River at the town of Lisala.</p>



<p>"If the appearance of the muddy Amazon River evokes a coffee cut with cream, the Ruki River, coursing gently through the Congo Basin, is like a dark tea," said NASA.</p>



<p>"On its slow path through mostly untouched lowland rainforest in the Democratic Republic of Congo (DRC), the water leaches organic material from vegetation, prompting some researchers to think it is one of the darkest blackwater rivers on Earth. The dissolved material in this distinctive water, scientists are finding, offers clues into the carbon cycle of tropical forests."</p>



<p>In a recent study, researchers measured the chemical composition and flow of the Ruki for the first time.&nbsp;</p>



<p>"The study reported that, as the water color suggests, the Ruki is rich in dissolved organic carbon compounds. It contains four times as much organic carbon as the Congo River and 1.5 times as much as the Rio Negro, the world’s largest blackwater river and a major tributary of the Amazon," said NASA.</p>



<p>Due to this heavy carbon load, the researchers concluded that “tropical forests like those around the Ruki might not accumulate quite as much carbon as we once thought.”</p>



<p>The region around the Ruki River is rich in biodiversity, hosting various species of flora and fauna. It is part of the Congo Basin, the second-largest tropical rainforest area in the world, which is a critical habitat for endangered species and a significant carbon sink.</p>



<p>The river is vital for the livelihoods of local communities. Fishing is a crucial activity, with many people depending on it for sustenance and income. The river also supports agriculture along its banks, where communities grow crops.</p>



<p>In many parts of the DRC, rivers like the Ruki are crucial transportation corridors due to the challenging and often nonexistent road infrastructure. The river enables the movement of people and goods, facilitating trade and access to markets, health care, and education.</p>



<p>The region faces several challenges, including deforestation, overfishing, and environmental degradation, which threaten its ecological balance and the livelihoods of people who depend on it. Efforts to manage and conserve the river's resources are vital for sustainable development.</p>



<p>Understanding and protecting the Ruki River and its surroundings are crucial for the DRC's environmental sustainability, economic development, and the well-being of its communities.</p>

The Ruki River in the Democratic Republic of the Congo

<p>Today's <strong>Image of the Day</strong> from <a href="https://earthobservatory.nasa.gov/">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/">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.&nbsp;</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. </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/">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/">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 <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>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 Ireland and the coasts of Scotland, Wales, and England along the North Atlantic Ocean.</p>



<p>"The image is from January 2024 and was captured on a relatively clear winter day. Ireland enjoys a mild climate, owing to the influence of the Atlantic Ocean (to the left) and the presence of the Gulf Stream. South-westerly winds from the Atlantic tend to bring a lot of rain in the northwest, west and southwest of the country," said ESA.</p>



<p>"The extensive grasslands that cover most of the country, washed by abundant rainfall all year, create the typical emerald-green landscape, hence it being known as the Emerald Isle. Brown rugged cliffs along the west coast frame the island’s green interior, speckled by hundreds of lakes, visible as dark spots in the image."</p>



<p>Ireland is divided into two distinct jurisdictions: the Republic of Ireland, which occupies most of the island, and Northern Ireland, which is part of the United Kingdom.&nbsp;</p>



<p>Ireland is the third-largest island in Europe, featuring a varied landscape of rolling hills, extensive plains, and rugged coastlines. Its highest peak is Carrauntoohil, part of the Macgillycuddy's Reeks range in County Kerry.&nbsp;</p>



<p>The island is encircled by the Atlantic Ocean, with the Celtic Sea to the south, St George's Channel to the southeast, and the Irish Sea to the east.</p>



<p>Ireland's history is marked by Viking invasions, Norman conquests, and centuries of English rule, culminating in a struggle for independence in the early 20th century.&nbsp;</p>



<p>The Republic of Ireland gained independence from the United Kingdom in 1922, following the Irish War of Independence. Northern Ireland, however, remained a part of the UK, leading to ongoing sectarian and political tensions, notably the "Troubles" in the late 20th century.</p>



<p><a href="https://www.earth.com/news/irish-community-survived-a-thousand-years-of-environmental-change/">Irish culture</a> is known worldwide for its literature, music, dance, and folklore. Notable literary figures include James Joyce, W.B. Yeats, and Samuel Beckett.&nbsp;</p>



<p>The country's cultural heritage is celebrated on St. Patrick's Day, Ireland's national holiday, observed globally with parades and festivities.</p>

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 a rare view of the total solar eclipse on April 8, 2024. </p>



<p>The image was captured about one million miles from Earth by NASA’s EPIC (Earth Polychromatic Imaging Camera) imager on the DSCOVR (Deep Space Climate Observatory) satellite.</p>



<p>The shadow of the <a href="https://www.earth.com/news/timeless-mystery-solved-scientists-uncover-what-is-inside-the-moons-core/">moon</a> swept across North America from the Pacific coast of Mexico to the Atlantic coast of Newfoundland, Canada.</p>



<h2 class="wp-block-heading" id="h-viewing-a-very-active-sun">Viewing a very active sun</h2>



<p>“As people in the 115-mile-wide (185-kilometer-wide) path of totality looked up and saw the moon conceal the bright orb of the sun and obscure all but its wispy corona, Earth-observing satellites captured imagery of the Moon’s shadow as it raced eastward over North America,” said NASA.</p>



<p>“Observers on the ground had a rare view of the sun’s active outer atmosphere, or corona. Glowing loops of plasma called solar prominences could also be seen extending into the corona. Plasma is super-hot ionized gas which flows along the tangled and twisted structure of the Sun’s magnetic fields.”</p>



<h2 class="wp-block-heading" id="h-approaching-a-solar-maximum">Approaching a solar maximum </h2>



<p>During a live broadcast of the eclipse from Dallas, NASA research scientist Michael Kirk noted that “this view of the corona will never happen again, ever.”&nbsp;</p>



<p>Kirk explained that the spiky and asymmetrical nature of the corona was a sign that the sun’s magnetic field was active and approaching <a href="https://www.earth.com/news/canyon-of-fire-solar-eruption-extended-more-than-60000-miles/">solar maximum</a>.</p>



<p>The next total solar eclipse to travel from coast to coast across the United States will be in 2045.</p>



<h2 class="wp-block-heading" id="h-what-is-a-total-solar-eclipse">What is a total solar eclipse?</h2>



<p>A total solar <a href="https://www.earth.com/news/earth-skies-full-eclipses-transits-exoplanets-know-where-to-look/">eclipse</a> is a celestial event that occurs when the moon passes directly between the Earth and the sun, completely obscuring the sun from view for a viewer on Earth. This alignment of the sun, moon, and Earth is known as syzygy.&nbsp;</p>



<p>During a total solar eclipse, the moon's apparent diameter is larger than the sun's, blocking all direct sunlight, and turning day into darkness. The sudden darkness of a total eclipse allows viewers to observe the solar corona, the outer atmosphere of the sun, which is usually hidden by the bright light of the sun's photosphere.</p>



<p>Total solar eclipses are relatively rare at any given location on Earth because the shadow of the moon (known as the umbra) that casts on the Earth's surface is very small compared to the Earth's surface area, and the path of totality (the path the shadow traces) is narrow</p>

Total solar eclipse captured from one million miles away

<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 Sombrero Galaxy, with its magnificent structure captured in stunning detail by the Hubble Space Telescope.</p>



<h2 class="wp-block-heading" id="h-sombrero-galaxy-nbsp">Sombrero Galaxy&nbsp;</h2>



<p>The Sombrero Galaxy, also known as Messier 104, is one of the most intriguing and easily recognizable <a href="https://www.earth.com/news/james-webb-captures-galaxies-that-are-too-old-to-exist/">galaxies</a> in the night sky, notable for its bright nucleus, large central bulge, and prominent dust lane that gives it a sombrero-like appearance when viewed from Earth. It is located in the constellation Virgo, about 29 million light-years away.</p>



<h3 class="wp-block-heading" id="h-appearance">Appearance</h3>



<p>Its most distinguishing feature is the dark dust lane that encircles the galaxy along its equator, resembling the rim of a sombrero hat. This dust lane is composed of interstellar dust and gas, where new stars are being born.</p>



<h3 class="wp-block-heading" id="h-galaxy-type-and-structure">Galaxy type and structure</h3>



<p>The Sombrero Galaxy is classified as an SA(s)a galaxy, indicating it is an unbarred spiral galaxy with a prominent nucleus. However, its large bulge and dust lane also give it characteristics of an elliptical galaxy and a lenticular galaxy, making it a hybrid of sorts.</p>



<h3 class="wp-block-heading" id="h-bright-nucleus">Bright nucleus</h3>



<p>The galaxy has a very bright nucleus, which is thought to house a <a href="https://www.earth.com/news/largest-map-of-supermassive-black-holes-unveiled/">supermassive black hole</a>. Observations suggest the black hole at its center is one of the most massive known, with an estimated mass of hundreds of millions of solar masses.</p>



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



<p>The Sombrero Galaxy spans about 50,000 light-years in diameter, making it about half the size of our Milky Way. Its halo is also populated with globular clusters, similar to the Milky Way, though the exact number is still a subject of research.</p>



<h3 class="wp-block-heading" id="h-research-and-discovery">Research and discovery</h3>



<p>Due to its unique features and relatively close proximity, the Sombrero Galaxy has been a focus of research and has been extensively studied across various wavelengths, from radio to X-ray. These studies have helped astronomers gain insights into the processes of galaxy <a href="https://www.earth.com/news/galaxies-like-our-own-milky-way-are-not-unique/">formation</a> and evolution.</p>



<h2 class="wp-block-heading" id="h-the-expanding-universe-model-nbsp">The expanding universe model&nbsp;</h2>



<p>The expanding universe model is a fundamental concept in cosmology that describes the <a href="https://www.earth.com/news/new-study-claims-our-universe-is-27-billion-years-old-double-the-current-age-estimate/">universe</a> as continuously growing in scale over time. This model is based on observations that galaxies are moving away from each other, with their separation increasing as time progresses.&nbsp;</p>



<p>The Sombrero Galaxy was one of the first galaxies to be identified as having a redshift, indicating it is moving away from us, which was an important piece of evidence supporting the expanding universe model. The key aspects of this model include:</p>



<h3 class="wp-block-heading" id="h-hubble-s-law">Hubble's Law</h3>



<p>In 1929, Edwin Hubble discovered that galaxies are receding from each other at velocities proportional to their distances. This relationship, known as Hubble's Law, provided the first observational evidence for the expanding universe. It suggests that the farther away a galaxy is, the faster it appears to be moving away from us.&nbsp;</p>



<p>This expansion is often described by the analogy of dots on an inflating balloon; as the balloon expands, the dots (representing galaxies) move away from each other.</p>



<h3 class="wp-block-heading" id="h-big-bang-theory">Big Bang Theory</h3>



<p>The expanding universe model is a cornerstone of the Big Bang theory, which posits that the universe began as a singular, extremely hot and dense point approximately 13.8 billion years ago. The universe has been expanding and cooling ever since. This theory explains the creation of all space, time, matter, and energy.</p>



<h3 class="wp-block-heading" id="h-cosmic-microwave-background-radiation">Cosmic Microwave Background Radiation</h3>



<p>The discovery of the CMB in 1965 provided strong evidence for the Big Bang theory and the expanding universe model. The CMB is the afterglow radiation from the Big Bang, observed as a faint microwave signal pervasive throughout the universe. It is considered a snapshot of the infant universe, showing a time about 380,000 years after the Big Bang when the universe had cooled enough for atoms to form and light to travel freely.</p>



<h3 class="wp-block-heading" id="h-accelerated-expansion">Accelerated Expansion</h3>



<p>Observations of distant supernovae in the late 20th century revealed that the universe's expansion is accelerating, not slowing down as previously assumed. This acceleration is attributed to a mysterious force termed "<a href="https://www.earth.com/news/dark-matter-does-not-exist-universe-27-billion-years-old-study/">dark energy</a>," which constitutes about 68% of the total energy content of the universe.</p>



<h3 class="wp-block-heading" id="h-cosmological-principle">Cosmological Principle</h3>



<p>The model is based on the cosmological principle, which states that on large scales, the universe is homogeneous (uniform in composition) and isotropic (appearing the same in all directions). This principle supports the observation that the expansion of the universe is uniform and not directed outward from a central point.</p>



<p>The expanding universe model has profoundly impacted our understanding of cosmology, leading to further inquiries into the nature of dark matter, dark energy, and the ultimate fate of the universe.</p>



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



<p>"NASA/ESA Hubble Space Telescope has trained its razor-sharp eye on one of the universe's most stately and photogenic galaxies, the Sombrero galaxy, Messier 104 (M104). The galaxy's hallmark is a brilliant white, bulbous core encircled by the thick dust lanes comprising the spiral structure of the galaxy," said ESA.</p>



<p>"As seen from Earth, the galaxy is tilted nearly edge-on. We view it from just six degrees north of its equatorial plane. This brilliant galaxy was named the Sombrero because of its resemblance to the broad rim and high-topped Mexican hat."</p>



<p>"At a relatively bright magnitude of +8, M104 is just beyond the limit of naked-eye visibility and is easily seen through small telescopes. The Sombrero lies at the southern edge of the rich Virgo cluster of galaxies and is one of the most massive objects in that group, equivalent to 800 billion suns. The galaxy is 50,000 light-years across and is located 30 million light-years from Earth."</p>

The brilliant Sombrero Galaxy hints at an expanding universe 

<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/">alpine glaciers</a> of Switzerland have lost more than half of their volume since the 1930s.</p>



<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>



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



<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/">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>

Corbassière glacier: Earth's climate archives are melting away

Plastic,Boxes,With,Pre-packaged,Vegetable,Salads,,Put,Up,For,Sale

<p>We use plastic wrap, containers, and <a href="https://www.earth.com/news/who-is-responsible-for-the-burden-of-plastic-packaging-waste/" target="_blank" rel="noreferrer noopener">packaging</a> all the time. It's convenient, affordable, and seemingly everywhere. Recent research by the Norwegian University of Science and Technology (<a href="https://www.ntnu.edu" target="_blank" rel="noreferrer noopener">NTNU</a>) reveals a shocking truth: our plastic food packaging harbors thousands of different chemicals that may pose significant health risks.</p>



<h2 class="wp-block-heading" id="h-chemicals-in-plastic-food-packaging">Chemicals in plastic food packaging</h2>



<p>Scientists uncovered a staggering 9,936 different chemicals within a single plastic product used to package food. This finding underscores the vast gaps in our understanding of the precise chemical makeup of everyday plastic items and their potential impacts on our well-being.</p>



<p>"Plastic is a very complex material that can contain many different chemicals, some of which can be harmful. This is also true for plastic food packaging,"&nbsp;says Martin Wagner, an NTNU professor who specializes in plastic chemicals.</p>



<h2 class="wp-block-heading" id="h-consequences-of-plastic-food-packaging">Consequences of plastic food packaging</h2>



<p>Many of the chemicals identified in <a href="https://www.earth.com/news/plastic-containers-may-release-forever-chemicals-into-food/" target="_blank" rel="noreferrer noopener">plastic</a> food packaging are not just passive elements; they actively disrupt crucial bodily functions. These disruptions can have profound and potentially long-term health effects.</p>



<h3 class="wp-block-heading">Messing with the metabolism</h3>



<p>Metabolism is essentially your body's engine. It converts the food you eat into energy, fuels cellular processes, and regulates how nutrients are stored and used. </p>



<p>This complex system is finely tuned, ensuring that your body functions efficiently. However, chemicals leached from <a href="https://www.earth.com/news/new-packaging-food-waste/" target="_blank" rel="noreferrer noopener">plastic</a> food packaging can interfere with this system. </p>



<p>For example, certain chemicals can mimic or block natural hormonal signals that control metabolism. This interference can lead to a decrease in metabolic efficiency, impacting energy levels, weight management, and overall health. </p>



<p>The disruption can also affect how your body processes vitamins and minerals, potentially leading to nutritional deficiencies.</p>



<h3 class="wp-block-heading">Hormonal havoc</h3>



<p>Hormones play a pivotal role in regulating virtually every bodily function, including growth, development, metabolism, and mood. They act as messengers, sending signals throughout the body to sustain balance and respond to environmental changes. </p>



<p>The chemicals found in plastic packaging, however, can disrupt this delicate balance. Some chemicals act as endocrine disruptors, which means they can mimic or inhibit natural hormones. </p>



<p>When these chemicals enter the body, they can bind to hormone receptors, block natural hormonal messages, or alter the normal production of hormones. </p>



<p>This disruption can lead to a multitude of health issues, ranging from developmental problems and reproductive issues to immune system dysfunctions and behavioral changes.</p>



<p>"In most of these <a href="https://www.earth.com/video/edible-biodegradable-food-packaging/" target="_blank" rel="noreferrer noopener">plastic</a> products, we found chemicals that can affect the secretion of hormones and metabolism," says Wagner.</p>



<h2 class="wp-block-heading" id="h-but-isn-t-plastic-inert">But isn't plastic inert?</h2>



<p>You might think that plastic is harmless – it's just a chemically neutral substance. However, as shown in another recent NTNU study, scientists found that several combinations of plastic chemicals can affect how your body sends and receives signals.</p>



<p>This finding suggests that plastic's impact goes beyond simple containment of goods. Instead, it actively engages with biological processes, potentially leading to a cascade of unwanted effects. </p>



<p>The implication here is stark: plastic, far from being chemically neutral, carries a variety of active compounds that can interfere with our body's most fundamental operations.</p>



<h2 class="wp-block-heading" id="h-what-can-we-do">What can we do?</h2>



<p>While the discovery of harmful chemicals in plastic food packaging is indeed concerning, it's important to remember that you have the power to make choices that reduce your exposure and improve your overall health.</p>



<h3 class="wp-block-heading">Choosing safer alternatives</h3>



<p>Glass or steel containers are considered to be the safest bet. These materials are inert, meaning they do not react with the foods stored inside them. </p>



<p>Glass and steel are durable, reusable, and free from the chemicals typically found in plastics. Using glass or stainless steel containers for everyday food storage and meal prep can significantly decrease your exposure to potentially harmful chemicals.</p>



<h3 class="wp-block-heading">Avoid heating food in plastic</h3>



<p>When plastic is heated, whether in a microwave or by other means, it increases the likelihood of chemical leaching. To avoid this risk, never use plastic containers for heating food in the microwave. Instead, transfer food to glass or ceramic containers that are designed to withstand high temperatures.</p>



<h3 class="wp-block-heading">Be informed and vigilant</h3>



<p>Start by familiarizing yourself with the materials used in the products you buy. Look specifically for products labeled "BPA-free". </p>



<p><a href="https://www.earth.com/news/common-plastic-items-pose-a-hidden-risk-to-childrens-gut-health/" target="_blank" rel="noreferrer noopener">Bisphenol A (BPA)</a> is one of the better-known chemicals that can leach from plastics and has been linked to various health issues, including hormonal disruptions and increased risk of cancer. </p>



<p>While BPA-free products are a safer choice, they may still contain other harmful chemicals, so continued caution and a push for broader safety testing and transparency in labeling are essential.</p>



<p>Taking these steps can significantly reduce your personal and family's exposure to harmful chemicals found in plastic products. </p>



<p>While broader change in how plastics are manufactured must come from industry and legislation, individual actions can collectively lead to greater demand for safer products and ultimately drive change in production practices.</p>



<h2 class="wp-block-heading" id="h-a-call-for-safer-plastics">A call for safer plastics</h2>



<p>Martin Wagner and his team believe the problem isn't plastic itself, but the chemicals added to it. With more research on exactly which chemicals pose the biggest threats, we may one day have plastic packaging that's completely safe – a win for both our health and the environment.</p>



<p>While we still don't know the long-term effects of constant exposure to these chemicals, scientists at NTNU believe that now is the time to overhaul our plastic manufacturing.</p>



<p>"These and previous findings show that plastic exposes us to toxic chemicals. They support the theory that we need to redesign plastic to make it safer," states Wagner.</p>

<p>Spring invites us to witness the spectacle of bird migrations. But have you ever wondered how <a href="https://www.earth.com/news/bird-flocks-social-relationships/" target="_blank" rel="noreferrer noopener">birds</a> manage such precise, collective movement? A recent study from New York University (<a href="https://www.nyu.edu" target="_blank" rel="noreferrer noopener">NYU</a>) offers fascinating insights into bird flocking and their aerodynamic mystery.</p>



<h2 class="wp-block-heading" id="h-bird-flocking-aerodynamics">Bird flocking aerodynamics</h2>



<p>A team of mathematicians has recently illuminated the dynamics behind large, swirling flocks of birds. The research reveals that birds heavily depend on aerodynamics - the science of air movement around objects - to coordinate their seemingly effortless flight. </p>



<p>Each <a href="https://www.earth.com/news/birds-lead-flock-strongest-flyers/" target="_blank" rel="noreferrer noopener">bird</a> functions as a compact, feathery powerhouse. Its wings do more than propel it forward; they also generate swirling air currents. These currents are crucial, as they enable birds to manipulate the airspace around them. This manipulation forms the intricate patterns and synchronized movements observed in flocks.</p>



<h2 class="wp-block-heading" id="h-invisible-springs">Invisible springs</h2>



<p>The scientists found that the air currents generated by <a href="https://www.earth.com/news/how-birds-brains-evolved-to-enable-them-to-fly/" target="_blank" rel="noreferrer noopener">birds</a> are not random. They interact with each other in a highly organized manner. These interactions, which resemble the behavior of springs, create a network of unseen forces that link neighboring birds. </p>



<p>The network helps maintain the positions of birds within the <a href="https://www.earth.com/news/mixed-species-foraging-flocks/" target="_blank" rel="noreferrer noopener">flock</a>. If birds drift from their spots, the interactive forces pull them back into place. This contributes to the overall stability and structure of the formation.</p>



<p>"If a flyer is displaced from its position, the vortices or swirls of flow left by the leading neighbor helps to push the follower back into place and hold it there," explained Leif Ristroph, a co-author of the study.</p>



<h2 class="wp-block-heading" id="h-small-bird-flocks">Small bird flocks</h2>



<p>While these helpful air currents create a beautiful order in small groups of birds, the system breaks down as the <a href="https://www.earth.com/news/birds-blend-in-to-adapt-to-diverse-environments/" target="_blank" rel="noreferrer noopener">flock</a> size increases. In larger flocks, the individual air currents from many birds start to clash and interfere with one another. This disruption weakens the stabilizing "spring" forces. </p>



<p>As a result, the formation becomes chaotic. Imagine lots of swirling forces bumping into each other. This leads to a loss of the organized structure seen in smaller flocks.</p>



<p>"The very long groups seen in some types of birds are not at all easy to form, and the later members likely have to constantly work to hold their positions and avoid crashing into their neighbors," explained Ristroph.</p>



<h2 class="wp-block-heading" id="h-flonons">Flonons</h2>



<p>When a large flock is overwhelmed by these clashing air currents, the disruption doesn't hit all the birds at once. Instead, the scientists observed a ripple effect – the disorganized movement started with certain birds and then spread throughout the rest of the flock in a wave-like pattern. </p>



<p>This chain reaction of jostling within the flock is a unique scientific phenomenon, and the researchers have given it a catchy name: "flonons." This term might become a new addition to our science vocabulary, especially as we learn more about the fascinating world of animal movement.</p>



<h2 class="wp-block-heading" id="h-broader-significance">Broader significance</h2>



<p>The discovery of how birds flock reveals more than just the remarkable abilities of these creatures; it has significant potential implications for human-designed systems and technologies. </p>



<p>The insights from studying aerodynamic interactions in bird flocks can enhance machine design. These insights could lead to more efficient, aerodynamically optimized machines. Possible improvements include better vehicle formation dynamics. </p>



<p>This would reduce drag and lower energy consumption. There could also be advancements in deploying autonomous drones that need to operate effectively in swarms.</p>



<p>Additionally, the principles of bird flocking could enhance the design of wind turbines, optimizing them for better energy capture based on how air flows naturally around objects in motion. This research bridges the gap between natural phenomena and engineered solutions, offering a blueprint for innovation across various fields.</p>



<p>“This area of research is important since animals are known to take advantage of the flows, such as of air or water, left by other members of a group to save on the energy needed to move or to reduce drag or resistance,” explained Ristroph.</p>



<p>The next time you see a flock of birds painting the sky with their organized chaos, remember: you're witnessing some seriously complex engineering by Mother Nature. It's a symphony of aerodynamics, invisible springs, and perhaps some squawky arguments over who gets the best drafting position.</p>



<p>The study is published in the journal <em><a href="https://www.nature.com/articles/s41467-024-47525-9" target="_blank" rel="noreferrer noopener">Nature Communications</a></em>.</p>

Bird flocking dynamics inspire advancements in technology

Spring invites us to witness the spectacle of bird migrations....

<p>Arbor Day originated in the United States during the early 1870s. The idea was conceived by J. Sterling Morton, a journalist and politician who moved from Detroit to the Nebraska Territory.&nbsp;</p>



<p>Morton was an agricultural enthusiast who recognized the environmental and economic value of trees. In the largely treeless plains of Nebraska, trees were needed for building materials, shade from the hot sun, and windbreaks to keep soil in place.</p>



<h2 class="wp-block-heading" id="h-origins-of-arbor-day">Origins of Arbor Day</h2>



<p>Morton first proposed a tree-planting holiday called "Arbor Day" at a meeting of the Nebraska State Board of Agriculture on January 4, 1872. The proposal was well received, and the first Arbor Day was celebrated in Nebraska on April 10, 1872. It was a huge success, with an estimated one million trees planted on that day.</p>



<p>The idea of an annual day specifically for planting trees quickly spread beyond Nebraska. Today, Arbor Day is observed in many countries around the world, each adapting the celebration to its own climate.&nbsp;</p>



<p>In the United States, it is typically celebrated on the last Friday in April, but many states observe the holiday on different dates that coincide with their local <a href="https://www.earth.com/news/planting-forests-with-diverse-tree-species-increases-likelihood-of-success/" target="_blank" rel="noreferrer noopener">tree planting</a> season. For example, Hawaii celebrates on the first Friday of November.</p>



<h2 class="wp-block-heading" id="h-why-are-trees-so-important">Why are trees so important?</h2>



<p>Trees are not just essential components of our natural landscape but vital guardians of our environment. These perennial plants do more than beautify our surroundings; they are fundamental to life on Earth.</p>



<h3 class="wp-block-heading" id="h-ecological-benefits-of-trees">Ecological benefits of trees</h3>



<p>The ecological significance of trees cannot be overstated. Primarily, they play a crucial role in mitigating climate change through carbon sequestration. Trees absorb <a href="https://www.earth.com/news/tree-rings-reveal-the-carbon-storage-capacity-of-a-forest/" target="_blank" rel="noreferrer noopener">carbon dioxide</a>, a predominant greenhouse gas, converting it into biomass through the process of photosynthesis. </p>



<p>This not only reduces the amount of harmful gases in the atmosphere but also provides us with oxygen, essential for life. A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year.</p>



<p>Furthermore, trees contribute to increased biodiversity. They serve as habitats for countless species. Birds, insects, fungi, and moss are just a few examples of the life forms that depend on trees for survival.&nbsp;</p>



<p>The variety of life supported by trees enhances genetic diversity, which is vital for adaptation and resilience in the face of environmental changes.</p>



<h3 class="wp-block-heading" id="h-economic-benefits-of-trees">Economic benefits of trees</h3>



<p>Economically, trees offer significant advantages. In urban areas, they improve home values by up to 15% or more due to their aesthetic appeal and their role in creating a pleasant microclimate.&nbsp;</p>



<p>Beyond aesthetics, trees provide raw materials for industries such as furniture, paper, and construction. Fruit and nut trees contribute to food resources, providing both nourishment and economic gains through agriculture.</p>



<p>Trees also have a profound impact on energy consumption. By providing shade and releasing moisture into the air through their leaves, trees can reduce the need for air conditioning in nearby buildings by 30%. This not only cuts down energy costs but also reduces the strain on power grids during peak summer months, thereby decreasing the likelihood of power outages.</p>



<h3 class="wp-block-heading" id="h-health-benefits">Health benefits</h3>



<p>The health benefits of trees extend beyond their environmental and economic contributions. They play a significant role in improving air quality by filtering pollutants such as dust, microplastics, and gases through their leaves and bark. Urban vegetation can reduce pollutants in the air by up to 25%, contributing to healthier <a href="https://www.earth.com/news/non-native-trees-have-enormous-value-in-urban-areas/" target="_blank" rel="noreferrer noopener">urban environments</a>.</p>



<p>Moreover, trees have been shown to have a positive impact on <a href="https://www.earth.com/news/urban-forest-bathing-fresh-breath-for-teen-mental-health/" target="_blank" rel="noreferrer noopener">mental health</a>. The presence of green spaces in urban areas can lower rates of psychological stress and illness. People living near trees often have lower levels of stress, and children diagnosed with attention deficit hyperactivity disorder (ADHD) show fewer symptoms when they have access to nature.</p>



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



<p>Despite their immense benefits, trees face numerous threats, including deforestation, land development, and climate change. These challenges underscore the need for concerted conservation efforts.&nbsp;</p>



<p>Planting trees is a simple yet powerful act that can lead to significant environmental improvements. Arbor Day and similar celebrations can serve as vital reminders of our responsibilities toward forest conservation and management.</p>



<h2 class="wp-block-heading" id="h-significance-of-arbor-day">Significance of Arbor Day</h2>



<p>Arbor Day is significant for several reasons, primarily centered around environmental awareness and conservation.</p>



<h3 class="wp-block-heading" id="h-education-and-awareness">Education and awareness</h3>



<p>Arbor Day serves as an opportunity to educate the public about the benefits that trees and <a href="https://www.earth.com/news/forests-play-an-overlooked-role-in-the-climate-system/" target="_blank" rel="noreferrer noopener">forests</a> provide to communities and the global environment. It encourages people to learn about tree care and forest management.</p>



<h3 class="wp-block-heading" id="h-community-involvement">Community involvement</h3>



<p>The day promotes community spirit as people come together to beautify their neighborhoods and public spaces. It is a chance for community engagement through collective action, which can strengthen community bonds and foster civic pride.</p>



<h3 class="wp-block-heading" id="h-legacy-and-sustainability">Legacy and sustainability</h3>



<p>Planting trees on Arbor Day is also about investing in the future. Trees planted today will grow to provide benefits for many years, making it a gesture of hope and sustainability for future generations.</p>



<p>Arbor Day serves as an important reminder that trees are more than just part of our natural landscape; they are essential for sustaining ecological balance, supporting economic development, and promoting health. By understanding and promoting the importance of trees, we can all contribute to a healthier, more sustainable world.&nbsp;</p>

Arbor Day: Honoring the guardians of our environment

Arbor Day originated in the United States during the early...

<p>Dog aggression is a serious concern for pet owners, as it can be unsettling, stressful, and even dangerous, not only for the dog but also for other pets, family members, and strangers.&nbsp;</p>



<p>Given the complexities and varying degrees of <a href="https://www.earth.com/news/understand-dogs-language-aggression/" target="_blank" rel="noreferrer noopener">aggressive</a> behaviors, Dr. Lori Teller, a clinical professor at the <a href="https://vetmed.tamu.edu/" target="_blank" rel="noreferrer noopener">Texas A&amp;M School of Veterinary Medicine and Biomedical Sciences</a>, provides expert guidance on recognizing and addressing these behaviors effectively.</p>



<h2 class="wp-block-heading" id="h-dog-aggression-with-no-apparent-trigger-nbsp">Dog aggression with no apparent trigger&nbsp;</h2>



<p>One particularly severe and complex form of aggression is rage syndrome, which causes dogs to exhibit extreme aggression without any apparent <a href="https://www.earth.com/news/dogs-appear-to-get-jealous-over-their-owners-affection/" target="_blank" rel="noreferrer noopener">triggers</a>. </p>



<p>“Dogs with rage syndrome have episodes of extreme aggression toward a person or other animals that occur seemingly out-of-the-blue and without provocation, yet they otherwise appear friendly and happy,” explained Dr. Teller.&nbsp;</p>



<p>This condition is notoriously challenging to diagnose and treat, since the causes, which may include genetic and neurological factors, remain unclear.&nbsp;</p>



<p>“No identifiable trigger leading up to the attack is one clear sign of rage syndrome. Additional signs include confusion or seeming dazedness during or immediately after an episode, glazed eyes, dramatic escalation of aggression without any warning, and unpredictability of episodes,” noted Dr. Teller.</p>



<h2 class="wp-block-heading" id="h-conflict-and-fear-based-dog-aggression">Conflict- and fear-based dog aggression</h2>



<p>It is crucial not to confuse rage syndrome with conflict- or fear-based aggression, which are more common and natural responses to perceived threats or conflicts.&nbsp;</p>



<p>According to Dr. Teller, there is usually a clearly identifiable trigger for other types of aggression, unlike with rage syndrome. Yet, some owners have difficulties reading a dog's <a href="https://www.earth.com/news/dogs-and-humans-process-social-information-in-surprisingly-similar-ways/" target="_blank" rel="noreferrer noopener">body language</a> or recognizing the trigger. </p>



<p>In cases of <a href="https://www.earth.com/news/aggressive-behavior-in-dogs-is-most-often-caused-by-fear/" target="_blank" rel="noreferrer noopener">fear-based</a> or conflict aggression, dogs often display warning signs before an attack, including a hunched body posture, lip-licking, trembling, baring teeth, growling, or snapping. </p>



<p>These forms of aggression are often defensive in nature, but dogs may also exhibit predatory behaviors that appear aggressive but are actually offensive and driven by the dog’s instinct to pursue prey.</p>



<h2 class="wp-block-heading" id="h-effectively-managing-aggression-nbsp">Effectively managing aggression&nbsp;</h2>



<p>When a dog exhibits aggressive behavior, owners should avoid intervening physically during an episode to prevent injuries. After the episode has subsided, it's crucial to consult a veterinarian.&nbsp;</p>



<p>“The veterinarian will obtain a complete behavioral history and probably perform some diagnostic tests to rule out a medical problem that has led to the aggressive behaviors,” said Dr. Teller. “An example of a medical problem that may trigger an aggressive response is when someone touches a painful area, such as with osteoarthritis or an ear infection.”</p>



<p>By contrast, “rage syndrome can be caused by seizure-like activity in the brain, so veterinarians may recommend an electroencephalogram, a test that measures electrical activity in the brain, or an advanced imaging modality such as an MRI or CT scan, which takes detailed images of the brain to identify any abnormalities in its structure,” she added.</p>



<h2 class="wp-block-heading" id="h-long-term-management-of-dog-aggression-nbsp">Long-term management of dog aggression&nbsp;</h2>



<p>Long-term management of aggression requires a comprehensive approach that includes both medical and behavioral interventions.&nbsp;</p>



<p>Depending on the underlying cause of aggression, dogs may be given an anxiolytic medication to relieve anxiety, an anticonvulsant to control the risk of seizures, or a combination of such medications. A behavioral modification plan is also essential and may involve referral to a veterinary behaviorist.</p>



<p>Understanding the different forms of aggression and seeking professional assistance when necessary can help dog owners provide the necessary care and support for their pets.&nbsp;</p>



<p>By addressing aggression effectively, the impact on the dog’s life and the broader household can be minimized, leading to a safer and more harmonious living environment.</p>



<h2 class="wp-block-heading" id="h-more-about-aggressiveness-in-dogs">More about aggressiveness in dogs</h2>



<p>Dog aggression is a significant behavioral issue that can manifest in various forms, ranging from growling and snapping to biting. It often arises due to multiple factors including genetics, lack of socialization, poor <a href="https://www.earth.com/news/dog-training-is-more-effective-when-nice-voice-tone-is-used/" target="_blank" rel="noreferrer noopener">training</a>, fear, or a previous negative experience. </p>



<p>Dogs may also exhibit aggressive behaviors when they're trying to assert dominance or protect their territory, owners, or resources such as food, toys, or other objects.</p>



<p>Understanding the triggers of aggression is crucial for managing it effectively. This involves observing when the aggression occurs, such as in the presence of other dogs or strangers, during meals, or in specific locations like their resting area.&nbsp;</p>

Can you control your dog’s aggression?

Dog aggression is a serious concern for pet owners, as...

<p>Let's face it: resisting that extra slice of chocolate cake or those tempting cookies can be a real struggle. We've all been there. But have you ever wondered why some people seem to have an easier time making healthy choices than others? New research suggests that our body mass index (BMI) might play a role in our snacking battles. Being <a href="https://www.earth.com/news/obesity-now-affects-more-than-a-billion-people/" target="_blank" rel="noreferrer noopener">overweight</a> changes brain activity and makes it harder to resist unhealthy foods.</p>



<h2 class="wp-block-heading" id="h-brain-dilemma-of-overweight-individuals">Brain dilemma of overweight individuals </h2>



<p>Canadian scientists from <a href="https://www.queensu.ca" target="_blank" rel="noreferrer noopener">Queen's University</a> conducted a study to understand how the brain influences our food choices. They used MRI scans to monitor the brain activity of 123 individuals. Participants were presented with different food choices and asked to make decisions.</p>



<p>The researchers discovered that individuals with a higher BMI experienced significantly more mental effort when choosing healthy foods over preferred snacks.</p>



<p>"We examined how brain states change when making natural and regulated dietary choices in an established food task. Individuals with lower weight status could successfully modify their eating behaviours while maintaining similar modes of brain activity. Individuals with higher <a href="https://www.earth.com/news/obesity-can-be-passed-down-from-parents-to-kids/" target="_blank" rel="noreferrer noopener">weight</a> status could not rely on this mechanism," noted the study authors.</p>



<p>The research highlights a concerning prediction: over 18% of the world's adult population will likely be obese by 2025. This statistic emphasizes that many people find it challenging to maintain a healthy diet.</p>



<h2 class="wp-block-heading" id="h-brain-activity-of-overweight-individuals">Brain activity of overweight individuals</h2>



<p>The Canadian study's key takeaway lies in how the brain orchestrates food choices in individuals with varying BMIs. Here's a deeper dive into what the researchers may have observed in the brain scans:</p>



<h3 class="wp-block-heading" id="h-lower-bmi">Lower BMI</h3>



<p>People with lower BMIs likely exhibited a steadier pattern of brain activity during food selection. This stability suggests their brains didn't require a significant shift in function to prioritize healthy options. </p>



<p>Over time, individuals with lower BMIs might have developed well-defined neural pathways associated with healthy eating behaviors. These pathways act like established highways within the brain, making healthy choices more automatic and requiring less conscious effort. </p>



<p>Another possibility is that the brains of individuals with lower BMIs might show less activation in areas linked to reward processing when presented with tempting, unhealthy options. Basically, these options might not trigger the same intense pleasure response in the brain, making it easier to resist them. </p>



<p>For example, for someone with a lower BMI, the brain's reward system might not light up as intensely when presented with a dessert compared to someone with a higher BMI. This dampened pleasure response could translate to a weaker craving and less difficulty in resisting the unhealthy option.  </p>



<h3 class="wp-block-heading" id="h-higher-bmi">Higher BMI</h3>



<p>The study suggests that people with a <a href="https://www.earth.com/news/excess-weight-in-middle-age-shortens-life-expectancy-by-years/" target="_blank" rel="noreferrer noopener">higher BMI</a> exhibited a more significant shift in brain activity during food choices. This heightened activity indicates their brains had to work considerably harder to overcome the allure of unhealthy options and prioritize healthy ones. </p>



<p>Individuals with a higher BMI might experience a surge in activity in brain regions associated with cravings and reward seeking when presented with unhealthy foods. This heightened response could be likened to a stronger signal on the brain's reward network, making it much more challenging to resist temptation. <br><br>To counteract the strong pull of unhealthy options, people with a higher BMI might need to activate areas of the brain responsible for cognitive control and decision-making to a greater degree. This increased mental effort might explain why some people find it so difficult to make healthy choices consistently. </p>



<p>Think of it like applying the brakes on a speeding car. The greater the temptation (speeding car), the harder the brain (driver) has to press the brakes (cognitive control) to resist the unhealthy option and choose the healthy one.</p>



<h2 class="wp-block-heading" id="h-cause-and-effect-mystery">Cause and effect mystery</h2>



<p>It's crucial to remember that this research is correlational, meaning it shows an association but doesn't prove that one causes the other. The researchers can't definitively say whether difficulty with healthy choices leads to <a href="https://www.earth.com/news/obese-higher-taste-satisfaction/" target="_blank" rel="noreferrer noopener">weight gain</a>, or whether weight gain changes the brain and makes healthy choices harder. More research is needed to untangle this cause-and-effect mystery.</p>



<p>The study offers a fascinating glimpse into the complex interplay between brain activity and food choices. It opens doors for future research to explore potential interventions that could help people, regardless of their BMI, make healthier choices with less internal struggle.</p>



<h2 class="wp-block-heading" id="h-brain-activity-from-being-overweight">Brain activity from being overweight</h2>



<p>The study proves several key points:</p>



<h3 class="wp-block-heading" id="h-it-s-not-just-about-willpower">It's not just about willpower</h3>



<p>For years, we've often been told that healthy eating is a simple matter of willpower. However, this study highlights that our biology plays a much larger role than previously understood. The brain's response to food cues, reward signaling, and the effort required for decision-making can significantly impact our choices.</p>



<p>This knowledge is essential because it can help remove the stigma and self-blame that often surrounds difficulty in maintaining a healthy diet. Understanding that there's a strong biological component can encourage a more compassionate approach toward oneself and others.</p>



<h3 class="wp-block-heading" id="h-biological-component">Biological component</h3>



<p>The research doesn't imply that people with high BMIs lack willpower. Rather, it suggests there may be underlying differences in brain wiring affecting how their brains process food choices. This difference makes resisting unhealthy options require significantly greater mental effort.</p>



<p>This understanding removes judgment from the equation. People struggling with their weight aren't "weak-willed" - their brains may simply be working differently. Acknowledging this biological component fosters empathy and moves the focus away from blame.</p>



<h3 class="wp-block-heading" id="h-potential-solutions-for-brain-activity-in-overweight-individuals">Potential solutions for brain activity in overweight individuals</h3>



<p>This research paves the way for developing effective and personalized strategies to help people manage their weight. Traditional approaches centered purely on willpower often fall short because they ignore this complex biological aspect.</p>



<p>By understanding how the brain influences food choices, scientists and healthcare professionals can develop interventions that address the root causes of the struggle. These interventions might include things like cognitive training, behavioral therapy, or possibly even targeted medications to support brain processes involved in healthy decision-making.</p>



<p>The study offers a beacon of hope, highlighting the potential for science to revolutionize how we approach weight management and improve dietary habits. It's a shift towards a more supportive and solution-focused outlook.</p>



<p>If you find yourself struggling with cravings, don't beat yourself up. Your brain might be working against you. Don't underestimate the power of small changes. </p>



<p>Even minor shifts in your eating habits can make a long-term difference. Seek support from healthcare professionals and explore resources for healthier eating.</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>



<p>"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. 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>
