The Ebro River on the northeast coast of Spain

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 United Arab Emirates, where a slow-moving storm system dumped more than a year's worth of rainfall in just a few hours. </p>



<p>“The UAE’s National Center for Meteorology reported that eastern parts of the country measured up to 250 millimeters (10 inches) of rain in less than 24 hours. UAE, known for its dry desert climate, receives only about 140 to 200 millimeters (5.5 to 8 inches) of rainfall per year,” said NASA.</p>



<p>“Dubai International Airport recorded 119 millimeters on April 16, which is 1.5 times its typical annual rainfall. The deluge temporarily halted flights at the airport, which is among the world’s busiest for international travel.”</p>



<h2 class="wp-block-heading" id="h-heaviest-rainfall-on-record-in-the-united-arab-emirates-nbsp">Heaviest rainfall on record in the United Arab Emirates&nbsp;</h2>



<p>Authorities noted that this was the heaviest <a href="https://www.earth.com/news/record-heat-fueled-unexpected-and-deadly-storms-in-2023/" target="_blank" rel="noreferrer noopener">rainfall</a> on record in the United Arab Emirates. The news agency WAM called it a historic weather event that surpassed “anything documented since the start of data collection in 1949.”&nbsp;</p>



<p>“Heavy rain triggered flash flooding across eastern parts of the country, inundating roads and disrupting transportation,” said NASA. “The system first hit Oman on April 14 and continued to batter the UAE through most of the day on April 16.”&nbsp;</p>



<p>At least 18 people were killed in the <a href="https://www.earth.com/news/heavy-rainfall-events-in-the-northeast-are-set-to-increase-by-over-50-percent/" target="_blank" rel="noreferrer noopener">heavy rains</a> in Oman, including ten children that were swept away in a vehicle with one adult, according to a statement from the country’s National Committee for Emergency Management.&nbsp;</p>



<h2 class="wp-block-heading" id="h-strong-low-pressure-system">Strong low-pressure system</h2>



<p>Michael Mann, a climate scientist at the University of Pennsylvania, noted that three low-pressure systems formed a train of <a href="https://www.earth.com/news/thunderstorms-are-becoming-more-intense-due-to-climate-change/" target="_blank" rel="noreferrer noopener">storms</a> slowly moving along the jet stream - the river of air that moves weather systems - toward the Persian Gulf.&nbsp;</p>



<p>“The strong low-pressure system delivered multiple rounds of high winds and heavy rain to the northern and eastern parts of the country,” said NASA. “Some areas remained flooded on April 19, when Landsat 9 passed over the region for the first time since the storms.”&nbsp;</p>



<p>Climate experts attribute such extreme weather events to <a href="https://www.earth.com/news/limiting-global-warming-to-1-5-degrees-celsius-would-save-billions-of-lives/" target="_blank" rel="noreferrer noopener">global warming</a>. According to a report from Reuters, researchers anticipate that climate change will lead to hotter temperatures, increased humidity, and a greater risk of <a href="https://www.earth.com/news/seeking-ways-to-prevent-flooding-caused-by-climate-change/" target="_blank" rel="noreferrer noopener">flooding</a> in parts of the Gulf region. “Countries like the UAE where there is a lack of drainage infrastructure to cope with heavy rains can suffer the most,” the report stated.&nbsp;</p>



<h2 class="wp-block-heading" id="h-more-about-the-united-arab-emirates-nbsp">More about the United Arab Emirates&nbsp;</h2>



<p>The United Arab Emirates (UAE) is a federation of seven emirates located on the eastern side of the Arabian Peninsula. It borders Oman and Saudi Arabia, and has maritime borders with Iran and Qatar in the Persian Gulf. Established as a federation in 1971, the UAE has rapidly developed into one of the most modern and wealthy nations in the world, largely thanks to its vast oil and natural gas reserves.</p>



<p>Abu Dhabi serves as the capital and is the largest emirate, both in terms of land area and economy, largely because it holds the majority of the UAE's oil reserves. Dubai is the most populous city and is renowned globally for its spectacular skyscrapers, including the Burj Khalifa, the tallest building in the world, as well as its bustling ports, and vibrant tourism and shopping sectors.</p>



<p>The UAE has a diverse and multicultural society with a significant expatriate population, drawn by business opportunities and the tax-free living in many sectors. The official language is Arabic, though English is widely spoken, especially in business and educational settings.</p>



<p>Politically, the UAE is a federal absolute monarchy. It is governed by a Supreme Council of Rulers made up of the seven emirs, who appoint the prime minister and the cabinet. The country has made significant strides in terms of infrastructure and healthcare, and it continues to invest heavily in various sectors including renewable energy, education, and technology.</p>



<p>Culturally, the UAE balances its rapid modernization with a strong commitment to traditional Arab culture. The heritage of the desert Bedouin lifestyle is celebrated with falconry, camel racing, and traditional dance remaining integral to its cultural festivities. The nation is also a major hub for international arts and sports events, enhancing its global profile and cultural footprint.</p>

Storms dumped record rainfall in the United Arab Emirates

<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 barred spiral galaxy NGC 3783, which is located about 130 million light-years away in the constellation Centaurus. NGC 3783 is also the most prominent of a galaxy group (by the same name) that contains 47 <a href="https://www.earth.com/news/james-webb-captures-galaxies-that-are-too-old-to-exist/" target="_blank" rel="noreferrer noopener">galaxies</a>. </p>



<h2 class="wp-block-heading" id="h-galaxy-groups">Galaxy groups</h2>



<p>“Like galaxy clusters, galaxy groups are aggregates of gravitationally bound galaxies. Galaxy groups, however, are less massive and contain fewer members than <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> do: where galaxy clusters can contain hundreds or even thousands of constituent galaxies, galaxy groups do not typically include more than 50,” noted ESA.</p>



<p>“The Milky Way is actually part of a galaxy group, known as the Local Group, which contains two other large galaxies (Andromeda and the Triangulum galaxy), as well as several dozen satellite and dwarf galaxies.”</p>



<h2 class="wp-block-heading" id="h-hd-101274-a-blue-giant-star">HD 101274: A blue giant star</h2>



<p>The bright object that appears to the right of the galaxy is the star HD 101274. “The perspective in this image makes the star and the galaxy look like close companions, but this is an illusion. HD 101274 lies only about 1,530 light-years from Earth, meaning it is about 85 thousand times closer than NGC 3783,” explained ESA.&nbsp;</p>



<p>HD 101274 is part of the NGC 3766 cluster, which is sometimes referred to as the Pearl Cluster, an open cluster known for its richness in bright stars and its relatively young age.</p>



<p>HD 101274 is categorized as a blue giant star, characterized by its high temperature and luminosity. Blue giants are massive stars that have left the main sequence phase of stellar evolution and are burning helium or heavier elements in their cores. These stars are known for their short lifespans relative to smaller stars due to their rapid consumption of nuclear fuel.</p>



<p><a href="https://www.earth.com/news/dark-stars-scientists-discover-a-new-type-of-star-powered-by-dark-matter/" target="_blank" rel="noreferrer noopener">Stars</a> like HD 101274 are important for astronomers because they help in studying the properties of stellar populations in clusters and the dynamics of stellar evolution in different environments. The spectral and photometric observations of such stars can provide valuable insights into the characteristics of their atmospheres, internal structures, and the processes occurring within and around them.</p>



<h2 class="wp-block-heading" id="h-bright-central-region-of-ngc-3783">Bright central region of NGC 3783</h2>



<p>One of the most interesting aspects of NGC 3783 is that it harbors an active galactic nucleus, meaning its central region is exceptionally luminous, likely due to the presence of a supermassive black hole. This black hole is actively accreting material, which emits a substantial amount of radiation as it spirals inward and heats up.</p>



<p>This galaxy is particularly known for its bright central region and has been studied extensively in the ultraviolet and X-ray light spectra to understand better the properties of the accretion disk around the black hole and the complex dynamics of the material surrounding it. These studies are crucial for understanding the physics of active galactic nuclei and the role they play in <a href="https://www.earth.com/news/galaxies-like-our-own-milky-way-are-not-unique/" target="_blank" rel="noreferrer noopener">galaxy evolution</a>.</p>



<p>According to ESA, NGC 3783 is a Type I Seyfert galaxy. “In this image it is recorded by Hubble in incredible detail, from its glowing central bar to its narrow, winding arms and the dust threaded through them, thanks to five separate images taken in different wavelengths of light," noted ESA.</p>



<p>“In fact, the galactic center is bright enough to Hubble that it exhibits diffraction spikes, normally only seen on stars such as HD 101274.”</p>



<h2 class="wp-block-heading" id="h-more-about-the-ngc-3783-galaxy-group">More about the NGC 3783 galaxy group</h2>



<p>The NGC 3783 group is part of the larger Hydra-Centaurus Supercluster, which itself is a massive collection of galaxies and galaxy clusters located primarily in the constellations of Hydra and Centaurus.</p>



<p>The NGC 3783 group consists of several galaxies that are gravitationally bound and interact with each other. These interactions can influence the galaxies' evolution through mechanisms like tidal forces and merger events, which can trigger star formation, fuel central black holes, and reshape the galaxies' structures.</p>



<p>Studying groups like the NGC 3783 group helps astronomers understand how <a href="https://www.earth.com/news/ceers-2112-ancient-galaxy-looks-strikingly-similar-to-ours/" target="_blank" rel="noreferrer noopener">galaxies</a> evolve together in a common gravitational environment, offering insights into the dynamics and evolution of structures on cosmic scales. This is especially relevant in understanding how galaxies influence each other through gravitational interactions and the environmental effects on galaxy evolution.</p>

The luminous galaxy NGC 3783 and a blue giant star

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 sediment swirling in the Gulf of Alaska on December 29, 2023.</p>



<p>"After an unusually snowy start to winter, southern Alaska’s coastline remained under a blanket of white in late December," said NASA.</p>



<p>"Meanwhile, greens and tans swirled in the dark blue water offshore. The dullness of the hues near shore suggests that the water is mostly colored by sediment. It is likely that phytoplankton - microscopic plant-like organisms - contributed to some of the hues farther from the coast."</p>



<p>According to NASA, much of the sediment in this region comes from “glacial flour” carried into the gulf by the Copper River.&nbsp;</p>



<p>"Glacial flour forms as glaciers move over bedrock and grind it into a fine silt. When suspended in water, glacial flour can make the water appear an opaque turquoise color - similar to phytoplankton blooms. The sediment carries iron and other nutrients that can spur the growth of these tiny marine organisms," explained NASA.</p>



<p>Aimee Neeley, a biological oceanographer at NASA’s Goddard Space Flight Center, noted that there are always phytoplankton in the water, but usually at lower levels in the wintertime at these latitudes.</p>



<p>The Gulf of Alaska is a vast and biologically rich body of water that lies at the northernmost part of the Pacific Ocean, encircled by Alaska.&nbsp;</p>



<p>The gulf extends approximately 1,500 miles from the Alaska Peninsula and the Aleutian Islands in the west to the Alexander Archipelago in the east.</p>



<p>Characterized by a subarctic climate, it's known for heavy rain and <a href="https://www.earth.com/news/sea-ice-loss-increases-snowfall-over-west-antarctica/">snowfall</a>. The region is also prone to frequent storms and is a significant pathway for colder northern weather patterns moving into the United States.</p>



<p>The Gulf of Alaska is home to a diverse marine ecosystem. It supports many species of fish, such as salmon and halibut, and is also a habitat for marine mammals like whales, sea lions, and seals.</p>



<p>The image was captured by the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument on NASA’s Aqua satellite.</p>

Sediment swirling in the Gulf of Alaska

<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 an astronaut view of the Aladaghlar Mountains in northwestern Iran. These mountains are known for their strikingly colorful landscapes, which make them stand out among other mountain ranges.</p>



<p>"Ridges cast shadows in the valleys and other low elevation areas, creating a three-dimensional appearance. Human alterations to the landscape are most evident in riverbeds, where the even topography is easier to build on and navigate," said NASA.</p>



<p>"Natural processes over millions of years have folded rock layers of various compositions and colors into the curved patterns seen here. These folds are produced by tectonic forces operating along the convergent plate boundary of the Arabia and Eurasia plates. The convergence of these tectonic plates causes uplift, folding, and deformation of the colorful rock layers, and subsequent erosion exposes them."</p>



<p>One of the most remarkable features of the Aladaghlar Mountains is the vivid coloration of their slopes. The name "Aladaghlar" translates to "Colorful Mountains," which is a testament to their unique appearance. </p>



<p>The Aladaghlar Mountains are part of a larger ecosystem that includes forests, meadows, and rivers, contributing to a rich biodiversity. The region supports a variety of wildlife, including several species that are unique to the area. The diverse wildlife add to the natural beauty and ecological importance of these <a href="https://www.earth.com/news/how-and-why-do-mountains-form-new-theories-for-an-age-old-mystery/">mountains</a>.</p>



<p>In addition to their natural appeal, the Aladaghlar Mountains hold cultural significance. The region has a rich history, with evidence of ancient civilizations and historical sites. Local communities have their unique cultures and traditions, which have been influenced by the natural environment of the mountains.</p>

The Aladaghlar Mountains of northwestern Iran

<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 large sediment plume from the Yangtze River that extends hundreds of kilometers off the coast of China.</p>



<p>"Brown, sediment-laden water is visible along this shallow, turbid stretch of coast year-round, but a vast plume like the one visible here is a characteristic feature of winter. Scientists have proposed several causes of this seasonal phenomenon," said NASA.</p>



<p>"The ebb and flow of tides contain enough energy to stir up sediments from the seafloor, a 2017 study found. While there are also tides in the summer, the models used in the study showed that sediment only rises to the surface in the winter. That’s when temperatures and salinities at the sea surface and bottom are similar, allowing for vertical mixing to occur and for sediment to churn higher into the water column."</p>



<p>Additional studies have suggested that the summer monsoon’s influence on currents impedes the eastward flow of sediment out of the estuaries, noted NASA.</p>



<p>"Despite what looks like a glut of suspended sediment in the water, the overall amount of it flowing from the Yangtze River has declined steadily over the past several decades. The construction of dams, including the Three Gorges Dam, has been the primary driver of this trend."</p>



<p>It is important for scientists to track the movement of suspended sediment. This material can cause direct harm to marine life, as well as indirect harm by blocking sunlight.</p>



<p>The Yangtze River, also known as the Chang Jiang in Chinese, is the longest river in Asia and the third-longest in the world, following the Nile and the <a href="https://www.earth.com/news/amazon-river-dolphins-are-at-great-risk-of-extinction-due-to-human-activities/">Amazon</a>. It flows for over 6,300 kilometers (about 3,917 miles) from the glaciers of the Qinghai-Tibet Plateau in western China to the East China Sea at Shanghai.&nbsp;</p>



<p>The Yangtze River basin is a key region for China's agriculture, industry, and hydroelectric power production. The river's waters are used for irrigation, navigation, and as a source of freshwater. The basin is home to diverse wildlife, including the critically endangered Yangtze river dolphin or Baiji, which may now be extinct.</p>

His Favorite Things

<p>Since the 1930s, the <a href="https://www.farmersalmanac.com/">Old Farmers' Almanac</a> has been publishing names for the full moons, drawing from what were termed “Indian” names that have since become widely recognized and utilized. </p>



<p>The full moon of April is often called the <a href="https://www.earth.com/news/the-pink-moon-will-shine-brightly-in-the-skies-tonight/">Pink Moon</a>, a name attributed to the herb moss pink or creeping phlox - also known as moss phlox, mountain phlox, and creeping phlox - which is native to the eastern United States and one of spring's earliest widespread flowers.&nbsp;</p>



<p>Other names for this April moon include the “Sprouting Grass Moon,” the “Egg Moon,” and the “Fish Moon,” the latter being used by coastal tribes to mark the time when shad fish move upstream to spawn.</p>



<h2 class="wp-block-heading" id="h-the-return-of-navigable-waterways">The return of navigable waterways</h2>



<p>Moreover, the names "Breaking Ice Moon" (Algonquin) and "Moon When the Streams Are Again Navigable" (Dakota) capture the thawing of ice and the return of navigable waterways typical of early spring. </p>



<p>The "Budding Moon of Plants and Shrubs" (Tlingit) and "Moon of the Red Grass Appearing" (Oglala) highlight the imminent surge in plant life as spring progresses.</p>



<h2 class="wp-block-heading" id="h-the-reemergence-of-life-in-april">The reemergence of life in April</h2>



<p>Additional names reflect the reemergence of <a href="https://www.earth.com/news/how-moonlight-affects-the-circadian-clocks-of-animals/">wildlife</a> during this season, such as the "Moon When the Ducks Come Back" (Lakota), "Moon When the Geese Lay Eggs" (Dakota), and "Frog Moon" (Cree), each indicating the return or increased activity of these species.</p>



<p>Similarly, the "Sucker Moon" (Anishinaabe) marks the period for harvesting sucker fish, which migrate to streams or shallow lake areas to spawn. </p>



<p>According to cultural lore, during this time, the sucker fish returns from the spirit world to cleanse the waterways and the life within them. </p>



<p>This name is sometimes used for the February Moon as well, to honor the sucker fish's role in sustaining the Anishinaabe people through the winter by providing a crucial food source.</p>



<h2 class="wp-block-heading" id="h-cultural-observances-and-april-s-full-moon">Cultural observances and April's full moon </h2>



<p>This moon also corresponds with significant cultural and religious observances in various parts of the world. It aligns with the Jewish festival of Pesach, or Passover, which in 2024 will begin at sundown on April 22 and conclude at nightfall on April 30. </p>



<p>The celebration starts in the middle of the Hebrew month of Nisan, with the Seder feasts taking place on the first two nights.</p>



<p>In the Hindu lunisolar calendar, which varies by region, this full <a href="https://www.earth.com/news/tonights-worm-moon-marks-the-beginning-of-spring/">moon</a> typically coincides with Hanuman Jayanti, the celebration of the birth of Lord Hanuman.</p>



<p>For Buddhists in Sri Lanka, this full moon is known as Bak Poya and commemorates the Buddha's visit to Sri Lanka, where he averted a war by settling a dispute between chiefs.</p>



<p>This lunar event falls near the middle of Shawwāl, the tenth month of the Islamic calendar, and during the third month of the Chinese Year of the Dragon.</p>



<p>In light of these diverse celebrations, people all over the world  are encouraged to wear festive celestial attire in honor of the full <a href="https://www.earth.com/news/timeless-mystery-solved-scientists-uncover-what-is-inside-the-moons-core/">moon</a>. </p>



<p>It’s a time to enjoy the burgeoning <a href="https://www.earth.com/news/spring-has-arrived-in-the-northern-hemisphere/">spring</a>, acknowledge these various cultural celebrations, set an extra seat at the table in a spirit of inclusivity, and importantly, strive for peace and not war.</p>



<h2 class="wp-block-heading" id="h-more-about-april-s-full-moon">More about April's full moon</h2>



<p>April’s full moon will reach its brightest point at 7:49 P.M. on Tuesday, April 23. Astronomically, the <a href="https://www.earth.com/news/the-pink-moon-will-shine-brightly-in-the-skies-tonight/">Pink Moon</a> signifies the time when the moon is fully illuminated by the sun as seen from Earth, appearing fully round.&nbsp;</p>



<p>“Like Earth, the Moon has a day side and a night side, which change as the Moon rotates,” explained <a href="https://www.nasa.gov/">NASA</a>. “The Sun always illuminates half of the Moon while the other half remains dark, but how much we are able to see of that illuminated half changes as the Moon travels through its orbit.”</p>



<p>The timing of the full moon varies slightly due to the lunar cycle averaging about 29.5 days. This leads to some variation in the date and time of the full moon each month.&nbsp;</p>



<h2 class="wp-block-heading" id="h-astrological-significance-of-the-pink-moon">Astrological significance of the Pink Moon</h2>



<p>In 2024, the Pink Moon falls on April 25th, during the sun’s transit through Taurus. This placement is quite significant astrologically for several reasons:</p>



<h3 class="wp-block-heading">Taurus Sun Scorpio Moon opposition</h3>



<p>The Pink Moon will be in the opposite sign of Scorpio, creating a full moon in Scorpio. This opposition highlights the balance between Taurus and Scorpio themes - material security and stability versus emotional depth and transformation. </p>



<p>It’s a potent time for delving into psychological matters, addressing issues of trust, and managing resources in relationships.</p>



<h3 class="wp-block-heading">Intensity and transformation</h3>



<p>Scorpio is a sign associated with intensity, depth, transformation, and the unseen. A full moon in Scorpio can bring to the surface deep-seated emotions and hidden truths. </p>



<p>This is a powerful time for healing, as it provides an opportunity to confront and release old wounds, secrets, or things that have been repressed.</p>



<h3 class="wp-block-heading">Financial and emotional investments</h3>



<p>Given Taurus’s influence on possessions and Scorpio’s on investments and shared resources, this full moon could highlight issues around finances, particularly what is owned individually versus jointly. It can prompt decisions about investments, loans, inheritances, or other financial matters.</p>



<h3 class="wp-block-heading">Enhanced intuition</h3>



<p>Scorpio’s watery, intuitive energy combined with the illuminating power of the full moon can enhance psychic abilities and deepen intuitive insights. This period may be particularly potent for those who practice divination or other metaphysical activities.</p>



<h3 class="wp-block-heading">Transformation and rebirth</h3>



<p>Scorpio is the sign of death and rebirth, so this full moon might signal a time of significant personal transformation. It can be an excellent period for ending unhealthy patterns or relationships and for beginning anew with a fresh perspective or renewed purpose.</p>

April's full "Pink Moon" tonight signifies the reemergence of life 

Since the 1930s, the Old Farmers' Almanac has been publishing...

<p>The tundra, a critical <a href="https://www.earth.com/news/mountains-both-carbon-sinks-and-carbon-sources/" target="_blank" rel="noreferrer noopener">carbon sink</a>, is undergoing significant changes due to the <a href="https://www.earth.com/news/australias-warming-climate-transforms-soil-into-a-carbon-emitter/" target="_blank" rel="noreferrer noopener">warming climate</a>. Traditionally known to store carbon, these vast, cold landscapes are now releasing it, potentially exacerbating climate change. </p>



<p>This shift is the focus of a recent comprehensive study that delves into how the warming climate affects carbon dynamics in tundra regions across the globe.</p>



<h2 class="wp-block-heading" id="h-warming-effect-on-tundra-sites">Warming effect on tundra sites</h2>



<p>To explore this phenomenon, a diverse team of 70 scientists from various countries embarked on an ambitious project. They implemented open-top chambers (OTCs) at 28 tundra sites worldwide to simulate increased temperatures. </p>



<p>The OTCs, functioning like mini-greenhouses, effectively trap heat and block wind, creating a localized warming effect. As a result, this method led to an average increase of 1.4 degrees Celsius in air temperature and 0.4 degrees in soil temperature. </p>



<p>Furthermore, soil moisture decreased by 1.6 percent, influencing the tundra's ability to function as a carbon sink.</p>



<h2 class="wp-block-heading" id="h-tundra-warming-and-carbon-release">Tundra warming and carbon release</h2>



<p>The experimental warming significantly impacted the tundra's ecosystem respiration, especially during the growing season, increasing it by 30 percent. </p>



<p>This increase is due to increased metabolic activities in soil organisms and plants, as noted by Sybryn Maes from <a href="https://www.umu.se/en/" target="_blank" rel="noreferrer noopener">Umeå University</a>.</p>



<p>"We knew from earlier studies that we were likely to find an increase in respiration with warming, but we found a remarkable increase – nearly four times greater than previously estimated, though it varied with time and location," said Maes.</p>



<h2 class="wp-block-heading" id="h-variability-across-tundra-regions">Variability across tundra regions</h2>



<p>The study also revealed that the increase in <a href="https://www.earth.com/news/can-plants-continue-offsetting-our-carbon-emissions-in-a-warming-world/" target="_blank" rel="noreferrer noopener">ecosystem respiration</a> varies with local soil conditions. Factors like nitrogen levels and soil pH play a role. This variability indicates that not all tundra regions respond uniformly to warming. </p>



<p>Professor Ellen Dorrepaal, also from Umeå University, emphasized the uniqueness of their findings. "Our work represents the first assessment of ecosystem respiration response to experimental warming across such a broad environmental gradient in the tundra, incorporating a comprehensive set of environmental drivers," said Professor Dorrepaal.</p>



<h2 class="wp-block-heading" id="h-broader-implications-for-arctic-and-alpine-regions">Broader implications for arctic and alpine regions</h2>



<p>The implications of these findings extend beyond the individual study sites. Matti Kummu from <a href="https://www.aalto.fi/en" target="_blank" rel="noreferrer noopener">Aalto University</a> highlighted the broader perspective.</p>



<p>"We see that some areas, particularly parts of Siberia and Canada, exhibit greater sensitivity to warming," said Kummu. "We anticipate an increase in respiration across the whole Arctic and alpine tundra, but more in situ data, particularly on the local soil conditions, is key to addressing the outstanding uncertainties and refining our predictions."</p>



<h2 class="wp-block-heading" id="h-refining-climate-models">Refining climate models  </h2>



<p>The researchers plan to further study how these experimental sites develop over time. They will also broaden their experiments to include new locations. </p>



<p>This ongoing work is essential for a more accurate understanding of <a href="https://www.earth.com/news/hidden-pool-of-global-soil-carbon-alters-climate-change-models/" target="_blank" rel="noreferrer noopener">climate change</a>'s impact on our planet's ecosystems and the broader climate system.</p>



<p>Additionally, the research highlights an urgent need for continuous exploration and monitoring of tundra regions. This is crucial to improve predictions and counteract global warming.</p>



<p>As the tundra shifts from being a carbon sink to a potential carbon source, grasping these dynamics grows increasingly crucial in our global efforts to effectively manage climate change.</p>



<h2 class="wp-block-heading" id="h-additional-impacts-of-warming-on-tundra">Additional impacts of warming on tundra</h2>



<p>Warming affects tundra in several critical ways beyond just increasing carbon emissions:</p>



<h3 class="wp-block-heading" id="h-permafrost-thawing"><strong>Permafrost thawing</strong></h3>



<p>As temperatures rise, permafrost - permanently frozen ground in the tundra - begins to thaw. This releases methane, a potent greenhouse gas, which further accelerates global warming.</p>



<h3 class="wp-block-heading" id="h-altered-plant-life"><strong>Altered plant life</strong></h3>



<p>Warming leads to changes in vegetation patterns. Shrubs and trees can start to encroach on traditional tundra landscapes, which alters the habitat and can disrupt the local biodiversity.</p>



<h3 class="wp-block-heading" id="h-increased-soil-erosion"><strong>Increased soil erosion</strong></h3>



<p>With less ice to stabilize the soil, warmer temperatures can increase erosion rates. This not only affects the physical landscape but can also release more carbon stored in the soil.</p>



<h3 class="wp-block-heading" id="h-biodiversity-los-s"><strong>Biodiversity los</strong>s</h3>



<p>The unique species adapted to cold tundra environments may struggle to survive in warmer conditions, leading to reduced biodiversity.</p>



<h3 class="wp-block-heading" id="h-changes-in-water-systems"><strong>Changes in water systems</strong></h3>



<p>Thawing permafrost affects water flows in the tundra. It can lead to the formation of new lakes and wetlands or the drying up of existing ones, significantly impacting local ecosystems and water availability.</p>



<p>Understanding these effects is crucial for predicting and mitigating the broader impacts of climate change on the tundra and its role in global ecological and climate systems.</p>



<p>The study is published in the journal <em><em><a href="https://www.nature.com/articles/s41586-024-07274-7" target="_blank" rel="noreferrer noopener">Nature</a></em></em>.</p>

Warming climate turns tundra from carbon sink to source

The tundra, a critical carbon sink, is undergoing significant changes...

<p>Cancer is a pervasive, complex disease responsible for weak immune systems, countless deaths, and untold suffering. Yet, there's hope on the horizon. Scientists are tirelessly unraveling cancer's mysteries. </p>



<p>One such breakthrough is immunotherapy, a cutting-edge approach that uses the body's own defenses to wage war against cancer cells. Researchers at <a href="https://www.vt.edu" target="_blank" rel="noreferrer noopener">Virginia Tech</a> are at the forefront of this research, developing a new type of immunotherapy with the potential to save lives.</p>



<h2 class="wp-block-heading" id="h-immune-system-and-cancer">Immune system and cancer</h2>



<p>Our immune system is a complex defense network made up of different cell types and organs. It works constantly to detect and eliminate threats, including harmful bacteria and viruses.</p>



<p>Cancer cells, unfortunately, develop ways to disguise themselves or suppress the immune system's response. This allows them to grow and spread unchecked.</p>



<p>Immunotherapy aims to outsmart cancer by enhancing the immune system's ability to recognize and destroy cancer cells. It introduces substances that either directly boost immune cells or remove the disguises cancer cells use to hide.</p>



<p>Unlike chemotherapy, which targets all rapidly dividing cells (both healthy and cancerous), immunotherapy is more precise. This often results in fewer harsh side effects for patients.</p>



<h2 class="wp-block-heading" id="h-the-challenge-with-immunotherapy">The challenge with immunotherapy</h2>



<p>Cytokines are small proteins that act as communication signals within the immune system. They play a critical role in coordinating the immune response, attracting and activating various immune cells to fight against threats.</p>



<p>“Cytokines are potent and highly effective at stimulating the immune cells to eliminate cancer cells,” said Professor <a href="https://che.vt.edu/People/faculty/Tong.html" target="_blank" rel="noreferrer noopener">Rong Tong</a>. “The problem is they’re so potent that if they roam freely throughout the body, they’ll activate every immune cell they encounter, which can cause an overactive immune response and potentially fatal side effects.”</p>



<p>The goal of scientists was to harness the power of cytokines to fight cancer while minimizing their potential side effects. This involved developing a method to deliver cytokines specifically to the tumor site, preventing their uncontrolled spread throughout the body.</p>



<p>Researchers at Virginia Tech addressed this challenge with their innovative localized cytokine therapy approach, providing a more targeted and controlled way to boost the immune system against cancer.</p>



<h2 class="wp-block-heading" id="h-immune-systems-anchored-cytokines-against-cancer">Immune systems anchored cytokines against cancer</h2>



<p>Dr. Tong teamed up with Dr. Wenjun "Rebecca" Cai to engineer a revolutionary approach to localized cytokine therapy. They developed tiny particles designed to carry the cytokine proteins directly to the tumor. These particles act as specialized delivery vehicles.</p>



<p>The particles are engineered with "anchors" – molecules on their surface that can bind specifically to components within the tumor. After injection, these anchors help the particles attach themselves firmly within the tumor environment.</p>



<p>The anchoring mechanism ensures that the cytokines remain primarily within the tumor. This prevents them from spreading throughout the body, minimizing potential harm to healthy cells, while allowing them to send powerful signals to attract immune cells to the tumor site.</p>



<h2 class="wp-block-heading" id="h-combination-therapy">Combination therapy</h2>



<p>Now, this alone is a remarkable advancement, but the researchers went one step further. They paired their anchored cytokine system with FDA-approved therapies called checkpoint blockade antibodies. </p>



<p>Cancer cells can develop mechanisms to suppress or deactivate immune cells, essentially disabling their ability to fight back. Checkpoint blockade antibodies target these mechanisms, re-activating the immune cells so they can attack the cancer.</p>



<p>The anchored cytokines act as a powerful amplifier, attracting large numbers of immune cells to the tumor site and enhancing their cancer-fighting capabilities. </p>



<p>This combined approach creates a synergistic effect – checkpoint blockade antibodies take away cancer's defenses, while the cytokines rally a powerful immune attack. Studies have demonstrated the significant success of this strategy in eliminating tumors.</p>



<h2 class="wp-block-heading" id="h-the-future-of-cancer-treatment">The future of cancer treatment</h2>



<p>This research is a tremendous leap forward in the field of immunotherapy, potentially leading to safer and more successful cancer treatments. It also opens doors for the development of similar delivery systems for other potent immune-boosting drugs.</p>



<p>“Researchers are still looking for safer and more effective cancer treatments,” said Tong. “This motivation is what drives us to develop new technologies in the field. The whole class of drugs that are employed to jump-start the immune system to fight cancer cells has largely not yet succeeded. Our goal is to create novel solutions that allow researchers to test these drugs with existing FDA-approved therapeutics, ensuring both safety and enhanced efficacy.”</p>



<p>The Virginia Tech researchers' dedication epitomizes the ongoing battle against cancer. While there's much work still ahead, projects like this provide immense hope that someday cancer will be a word that loses its terrifying power.</p>



<p>“I view this project as a perfect marriage between chemical engineering and materials science,” Cai said. “The former focuses on the synthesis and drug delivery part, the latter on applying advanced materials characterization. This collaboration not only accelerates immunotherapy research, but also has the ability to transform cancer treatment.”</p>



<p>The study is published in the journal <em>Science Advances</em>.</p>

Reprogramming the immune system to attack cancer cells

Cancer is a pervasive, complex disease responsible for weak immune...

<p>In a new study, researchers have explored how modern adults perceive the onset of old age compared to previous generations. The experts found that, as <a href="https://www.earth.com/news/women-in-the-us-now-live-6-years-longer-than-men-as-life-expectancy-gap-widens/" target="_blank" rel="noreferrer noopener">life expectancy</a> increases and retirement ages are pushed back, the public perception of when old age begins is shifting to later in life. </p>



<p>The study was led by an international team of researchers including psychologist Markus Wettstein from <a href="https://www.hu-berlin.de/en" target="_blank" rel="noreferrer noopener">Humboldt University</a> in Berlin, and his colleagues from <a href="https://www.stanford.edu/" target="_blank" rel="noreferrer noopener">Stanford University</a>, the <a href="https://www.uni.lu/en/" target="_blank" rel="noreferrer noopener">University of Luxembourg</a>, and the <a href="https://www.uni-greifswald.de/en/" target="_blank" rel="noreferrer noopener">University of Greifswald</a>.</p>



<h2 class="wp-block-heading" id="h-notable-shift-in-the-perceived-start-of-old-age-nbsp">Notable shift in the perceived start of old age&nbsp;</h2>



<p>The experts analyzed responses from 14,056 participants in the <a href="https://www.dza.de/en/research/deas" target="_blank" rel="noreferrer noopener">German Aging Survey</a>. This longitudinal study spans over 25 years and includes German residents born between 1911 and 1974, assessing their views on aging.</p>



<p>The survey consistently asked participants the age at which they considered someone to be old. Findings indicate a notable shift: participants born earlier in the 20th century identified the start of old age at younger ages than those born later. For instance, participants born in 1911 believed old age started at 71 when they were 65 years old, whereas those born in 1956 placed the threshold at 74.</p>



<p>However, the scientists identified a slowdown in this trend of pushing back the perceived start of old age in recent decades, suggesting that this shift might not continue indefinitely. “The trend toward postponing old age is not linear and might not necessarily continue in the future,” Wettstein explained.</p>



<h2 class="wp-block-heading" id="h-aging-changes-the-perspective-nbsp">Aging changes the perspective&nbsp;</h2>



<p>Further analysis showed that as individuals age, they tend to view old age as beginning later in life. For example, at age 64, participants on average believed old age started at 74.7, but by age 74, they adjusted this belief to 76.8. This shift roughly translates to a one-year increase in the perceived start of old age for every four to five years of actual aging.</p>



<p><a href="https://www.earth.com/news/sleep-gender-equal-countries/" target="_blank" rel="noreferrer noopener">Gender</a> and health also play significant roles in how early individuals perceive the onset of old age. The study found that women, on average, believe it starts about two years later than men do, a gap that has widened over time. Moreover, individuals who reported feeling lonelier, being in poorer health, or feeling older themselves tended to say old age starts earlier.</p>



<h2 class="wp-block-heading" id="h-what-drives-the-trend-of-postponing-old-age">What drives the trend of postponing old age?</h2>



<p>These findings are critical for understanding how individuals plan for their aging and how society views older adults. “It is unclear to what extent the trend towards postponing old age reflects a trend towards more positive views on older people and aging, or rather the opposite - perhaps the onset of old age is postponed because people consider being old to be an undesirable state,” Wettstein said.</p>



<p>The experts call for further research to determine if this trend will persist and to expand the scope of inquiry to more diverse and non-Western populations, to better understand global perceptions of aging.</p>



<h2 class="wp-block-heading" id="h-interesting-facts-about-old-age">Interesting facts about old age</h2>



<p>Old age can be a period of growth, adaptation, and continued contribution to society, not merely a time of decline. Here are some interesting facts:</p>



<h3 class="wp-block-heading" id="h-increased-life-expectancy">Increased life expectancy</h3>



<p>Globally, life expectancy has significantly increased over the past century. Advances in healthcare, nutrition, and living conditions have played a major role in extending the average <a href="https://www.earth.com/news/dietary-restriction-slows-brain-aging-and-increases-lifespan/" target="_blank" rel="noreferrer noopener">lifespan</a>.</p>



<h3 class="wp-block-heading" id="h-healthier-senior-years">Healthier senior years</h3>



<p>Many older adults today are healthier than in the past. Improved medical treatments for chronic diseases like heart disease and arthritis mean many seniors can maintain a better quality of life for longer.</p>



<h3 class="wp-block-heading" id="h-brain-plasticity">Brain plasticity</h3>



<p>Contrary to the belief that the brain's <a href="https://www.earth.com/news/older-adults-brain-cells/">capabilities</a> decline unavoidably with age, research shows that the brain maintains plasticity into older adulthood, meaning it can continue to form new neural connections and adapt.</p>



<h3 class="wp-block-heading" id="h-population-shifts">Population shifts</h3>



<p>The demographic of <a href="https://www.earth.com/news/nature-improves-life-quality-of-older-adults/" target="_blank" rel="noreferrer noopener">older adults</a> is increasing faster than other age groups. By 2050, the number of people aged 60 years and older will more than double. This shift is challenging societies to adapt infrastructures and policies to meet the needs of an aging population.</p>



<h3 class="wp-block-heading" id="h-economic-impact">Economic impact</h3>



<p>Older adults contribute significantly to the economy, often referred to as the "silver economy." This includes not just their spending power but also their contributions to the workforce and volunteer sectors.</p>



<h3 class="wp-block-heading" id="h-wisdom-and-emotions">Wisdom and emotions</h3>



<p>Older adults often experience what is known as the "positivity effect,” a tendency to remember positive experiences over negative ones. Studies suggest that this might be an adaptive mechanism to enhance overall well-being.</p>



<h3 class="wp-block-heading" id="h-cultural-differences">Cultural differences</h3>



<p>Attitudes towards aging vary significantly by culture. In some cultures, older adults are revered and considered wise, whereas, in others, youth is valued more.</p>



<p>The study is published in the journal <a href="http://dx.doi.org/10.1037/pag0000812" target="_blank" rel="noreferrer noopener"><em>Psychology and Aging</em></a>.</p>

Public perception of ‘old age’ has shifted to later in life

In a new study, researchers have explored how modern adults...

Cbn,Cannabinoloil,And,Marijuana.,Formula,Cannabis,.,Weed,Decriminalization,.

<p>Did you know that a compound found in the <a href="https://www.earth.com/news/cannabis-legalization-does-not-increase-youth-substance-abuse/" target="_blank" rel="noreferrer noopener">cannabis</a> plant might protect your brain from damage and decline? It's called cannabinol (CBN), and it's not the THC you're probably familiar with. </p>



<p>Researchers at the <a href="https://www.salk.edu" target="_blank" rel="noreferrer noopener">Salk Institute</a> are delving into cannabinol's secrets, uncovering its potential to revolutionize how we treat brain injuries and diseases like Alzheimer's and Parkinson's.</p>



<h2 class="wp-block-heading" id="h-what-is-cannabinol">What is cannabinol?</h2>



<p>You've probably heard of THC, the compound in <a href="https://www.earth.com/news/chemical-found-in-cannabis-plants-can-actually-reduce-cannabis-induced-anxiety/" target="_blank" rel="noreferrer noopener">cannabis</a> responsible for its well-known "high", and CBD, known for its potential therapeutic benefits. Cannabinol is a lesser-known cannabinoid, also derived from the cannabis plant. </p>



<p>While it does have some mild psychoactive effects, they are significantly less pronounced than those of THC. What makes CBN particularly interesting to scientists is its potential to protect our brains.</p>



<p>Think of your brain as being filled with tiny energy-producing factories called mitochondria. These powerhouses are essential for keeping brain cells healthy and functioning. Unfortunately, in diseases like Alzheimer's or after a traumatic brain injury, these mitochondria can malfunction and break down. </p>



<p>This leads to the death of <a href="https://www.earth.com/news/recreational-cannabis-use-protects-against-cognitive-decline/" target="_blank" rel="noreferrer noopener">brain</a> cells, which contributes to the devastating symptoms of these conditions. CBN appears to have the ability to intervene in this process, acting to support and protect these failing mitochondria. </p>



<p>This safeguarding effect of cannabinol could be key to slowing or preventing the damage caused by brain-related diseases and injuries.</p>



<h2 class="wp-block-heading" id="h-cannabinol-components-to-protect-brain">Cannabinol components to protect brain</h2>



<p>To identify the specific components of CBN responsible for its protective effects, the researchers carefully deconstructed the molecule into smaller fragments. This allowed them to isolate and analyze the active parts.</p>



<p>Armed with the knowledge of CBN's most potent fragments, the scientists created four new compounds inspired by CBN's structure but with those supercharged active parts amplified. These enhanced versions of CBN aimed to provide even greater brain protection than the original molecule.</p>



<h2 class="wp-block-heading" id="h-cannabinol-s-impact-on-the-brain">Cannabinol's impact on the brain</h2>



<p>The Salk team's research pinpointed a specific way brain cells can die, called oxytosis/ferroptosis. This type of cell death plays a role in various neurological diseases, causing significant damage. The new CBN-inspired compounds demonstrated the ability to protect brain cells from this harmful process.</p>



<p>In laboratory tests using both mouse and human brain cells, the enhanced compounds showed protective abilities that matched the effectiveness of natural CBN. This means they offer the potential benefits of CBN but may do so even more powerfully.</p>



<p>To gauge the real-world impact of these compounds, scientists used fruit flies with traumatic brain injury, a common model for studying these types of injuries in humans. One compound, named CP1, shone brightly in this study. </p>



<p>Flies treated with CP1 had significantly higher survival rates than untreated flies, suggesting CP1 could play a critical role in minimizing the devastating consequences of brain trauma.</p>



<h2 class="wp-block-heading" id="h-more-about-cannabinol-beyond-its-brain-benefits">More about cannabinol beyond its brain benefits</h2>



<p>As discussed above, cannabinol is a cannabinoid derived from the cannabis plant, known mostly for being mildly psychoactive and primarily found in aged cannabis where THC has degraded over time. Here's a bit more about CBN:</p>



<h3 class="wp-block-heading">Origins and chemical nature</h3>



<p>CBN forms when THC, the primary psychoactive compound in cannabis, is exposed to oxygen and light. Over time, THC breaks down and converts into CBN. Compared to THC, CBN has a lower psychoactive effect, which makes it less potent but potentially more suitable for medical use without strong euphoric effects.</p>



<h3 class="wp-block-heading">Potential Medical Benefits</h3>



<ul>
<li><strong>Sleep aid:</strong> CBN is often marketed as a sleep aid or sedative, with some reports suggesting it can help users fall asleep faster and sleep more soundly.</li>



<li><strong>Pain relief:</strong> It may work as an analgesic or pain reliever, particularly when combined with other cannabinoids like CBD.</li>



<li><strong>Anti-inflammatory:</strong> Like other cannabinoids, CBN has shown anti-inflammatory properties, which could be beneficial in treating conditions like arthritis.</li>



<li><strong>Neuroprotectant:</strong> As demonstrated in the Salk Institute's research, CBN may offer neuroprotective effects, making it a candidate for treating neurodegenerative diseases.</li>



<li><strong>Antibacterial:</strong> Studies have shown that CBN can act as an antibacterial agent, effective against various bacterial strains including MRSA.</li>
</ul>



<h3 class="wp-block-heading">Use and Accessibility</h3>



<p>The legal status of CBN can vary depending on local laws, especially as it is derived from cannabis. In regions where cannabis is legal, products containing CBN are becoming more available.</p>



<p>While there is promising research supporting CBN’s efficacy, more clinical studies are necessary to fully understand its therapeutic potential.</p>



<h2 class="wp-block-heading" id="h-the-future-of-brain-health">The future of brain health</h2>



<p>"Our findings help demonstrate the therapeutic potential of CBN, as well as the scientific opportunity we have to replicate and refine its drug-like properties," says Research Professor Pamela Maher, senior author of the study.</p>



<p>Imagine giving this CP1 compound to athletes at risk for head injuries or to someone immediately after a car accident. Could it lessen the long-term consequences of brain trauma? </p>



<p>The Salk team is determined to find out. Their future research will explore these enhanced CBN compounds in the context of age-related brain decline, potentially changing how we approach brain health as we age.</p>



<p>The study is published in the journal <em><a href="https://www.sciencedirect.com/science/article/pii/S2213231724001149" target="_blank" rel="noreferrer noopener">Redox Biology</a></em>.</p>

<p>Astronomers have recently created a high-resolution map showcasing a colossal outflow of gas within the nearby galaxy NGC 4383. This galactic explosion is shedding light on the intricate processes that contribute to the <a href="https://www.earth.com/news/massive-star-explosion-created-elements-essential-for-life/" target="_blank" rel="noreferrer noopener">chemical</a> enrichment of intergalactic space and provides clues about the mechanisms that regulate galaxy evolution.</p>



<h2 class="wp-block-heading" id="h-intergalactic-enrichment">Intergalactic enrichment</h2>



<p>Galaxies are vast, dynamic environments where stars act as cosmic factories, transforming simple elements into heavier ones throughout their lives. During their final, explosive stages – called supernovae – these <a href="https://www.earth.com/news/hubble-detects-awe-inspiring-newborn-star/" target="_blank" rel="noreferrer noopener">stars</a> blast out immense quantities of gas laced with the complex elements they've created.</p>



<p>This stellar debris mixes with the existing gas and dust within the galaxy, a region known as the interstellar medium. The infusion of these heavier elements increases the overall richness of the interstellar medium, providing new building blocks for subsequent generations of stars and planets.</p>



<p>Through this process of cosmic recycling – stellar birth, element production, supernova dispersal, and the formation of new celestial bodies – galaxies steadily evolve and change their chemical makeup.</p>



<h2 class="wp-block-heading" id="h-galactic-explosion-in-ngc-4383">Galactic explosion in NGC 4383</h2>



<p>The detailed observations of NGC 4383 have revealed a truly exceptional gas outflow, emphasizing the scale and power of such galactic explosions within galaxies. Key findings of this study include:</p>



<h3 class="wp-block-heading" id="h-scale-and-velocity">Scale and velocity</h3>



<p>The sheer size of the expelled gas is extraordinary. Traveling at light speed, it would take 20,000 years to cross the entire structure. To put the velocities into perspective, the ejected material speeds outward in excess of 200 kilometers per second – hundreds of times faster than a bullet train.</p>



<h3 class="wp-block-heading" id="h-chemical-composition">Chemical composition</h3>



<p>Scientists analyzed the light from the outflow to determine its makeup. They discovered a diverse mixture of heavier elements, including essential building blocks of life like oxygen, nitrogen, and sulfur, along with numerous others. This indicates that the outflow is not just leftover debris, but a treasure trove of ingredients for future cosmic structures.</p>



<h3 class="wp-block-heading" id="h-mass">Mass</h3>



<p>Astonishingly, the total mass contained within this outflow is equivalent to over 50 million times the mass of our Sun. This underscores the immense energy involved in such galactic events and the substantial amount of material they can displace.</p>



<h2 class="wp-block-heading" id="h-capturing-ngc-4383-s-outflow">Capturing NGC 4383's outflow</h2>



<p>This significant breakthrough highlights the power of advanced astronomical tools and surveys in pushing the boundaries of our knowledge. Here's a breakdown of the key components:</p>



<h3 class="wp-block-heading" id="h-mauve-survey">MAUVE survey</h3>



<p>This large-scale project meticulously maps galaxies using cutting-edge instruments. Its aim is to understand how galaxies evolve, including investigating the role of gas flows into and out of these cosmic structures.</p>



<h3 class="wp-block-heading" id="h-muse-integral-field-spectrograph">MUSE integral field spectrograph</h3>



<p>MUSE is a sophisticated instrument that collects light and splits it into its component colors (a spectrum). Crucially, it does this simultaneously for many points across an extended object like NGC 4383's gas outflow. This allows scientists to map the velocity, temperature, and chemical composition of the outflow in unprecedented detail.</p>



<h3 class="wp-block-heading" id="h-european-southern-observatory-s-very-large-telescope-vlt">European southern observatory's Very large telescope (VLT)</h3>



<p>The VLT is a world-leading astronomical observatory located in Chile. It consists of multiple telescopes that operate together and are equipped with state-of-the-art instruments like MUSE, enabling researchers to make groundbreaking discoveries.</p>



<p>The combination of the MAUVE survey's focus, MUSE's capabilities, and the power of the VLT telescopes provided the ideal conditions for scientists to capture such stunning details of NGC 4383's remarkable outflow.</p>



<h2 class="wp-block-heading" id="h-implications-of-ngc-4383-s-explosion-for-galactic-evolution">Implications of NGC 4383's explosion for galactic evolution</h2>



<p>“Very little is known about the physics of outflows and their properties because outflows are very hard to detect,” noted lead author Dr Adam Watts, from <a href="https://www.uwa.edu.au" target="_blank" rel="noreferrer noopener">The University of Western Australia</a> node at the International Centre for Radio Astronomy Research (<a href="https://www.icrar.org/">ICRAR</a>). The case of <a href="https://www.earth.com/image/the-luminous-galaxy-ngc-3783-and-a-blue-giant-star/" target="_blank" rel="noreferrer noopener">NGC</a> 4383 addresses this challenge, offering fresh insights into galactic outflows. These processes play a crucial role in several facets of galaxy evolution:</p>



<h3 class="wp-block-heading" id="h-regulation-of-star-formation">Regulation of star formation</h3>



<p>Stars are born within dense clouds of gas and dust within galaxies. This raw material needs to collapse under its own gravity to trigger star formation.</p>



<p>Powerful outflows, driven by things like supernova <a href="https://www.earth.com/news/t-coronae-borealis-blaze-star-explosion-visible-one-week/" target="_blank" rel="noreferrer noopener">explosions</a> and intense radiation from massive stars, act like a powerful cosmic broom. They can disrupt and disperse the gas clouds, essentially removing the fuel needed for future star formation.</p>



<p>When star-forming material is swept away, the galaxy has a harder time making new stars. This can significantly slow down the overall rate of star formation and affect how long a galaxy remains actively star-forming.</p>



<p>Outflows are a crucial regulating mechanism in galaxies. Without them, galaxies might burn through their star-forming fuel too quickly. Outflows help galaxies maintain a more sustainable level of star formation over long periods of time.</p>



<h3 class="wp-block-heading" id="h-ngc-4383-s-long-term-legacy">NGC 4383's long-term legacy</h3>



<p>The gas ejected by galactic outflows doesn't just vanish into the void. Instead, it becomes a part of the vast intergalactic medium – the <a href="https://www.earth.com/news/cassiopeia-a-resembles-a-shiny-christmas-ornament-in-this-webb-telescope-photo/" target="_blank" rel="noreferrer noopener">space</a> between galaxies.</p>



<p>Over time, the dispersed material mixes with the existing gas in the intergalactic medium. This gradually alters its overall chemical makeup, increasing the abundance of heavier elements produced in stars.</p>



<p>These enriched pockets of intergalactic gas could then influence subsequent galaxy formation. When new galaxies form, they draw in this material, starting off with a more complex mix of elements than the earliest galaxies in the universe.</p>



<p>Galactic outflows leave a lasting chemical fingerprint on the cosmos. They play a subtle but essential role in the universe's ongoing evolution.</p>



<p>"We hope that in the future, MAUVE observations reveal the importance of gas outflows in the local Universe with exquisite detail," commented Professor Barbara Catinella, co-author and co-leader of the MAUVE survey. NGC 4383 provides a fascinating puzzle piece, helping astronomers understand the complex interplay between stars, galaxies, and the grand tapestry of the cosmos.</p>

<p>Have you ever felt like your <a href="https://www.earth.com/news/mental-health-crisis-half-of-the-worlds-population-will-be-affected-by-age-75/" target="_blank" rel="noreferrer noopener">mental</a> health has kept you from fully living your life? Struggling with depression or anxiety can make it seem like time itself slows down, trapping you in a cycle of worry and fogginess. </p>



<p>According to a new nationwide survey, called the <a href="https://genesight.com" target="_blank" rel="noreferrer noopener">GeneSight</a> Mental Health Monitor, you're not alone. A staggering amount of Americans report losing precious time due to poor mental health.</p>



<h2 class="wp-block-heading" id="h-poor-mental-health-and-lost-time">Poor mental health and lost time</h2>



<p>The survey results paint a devastating picture of the toll mental illness takes. The fact that 44% of Americans believe they've lost significant time due to poor mental health highlights the widespread reach of this issue. </p>



<p>For those already diagnosed with anxiety and/or depression, the situation worsens dramatically – nearly 80% report the same heartbreaking sense of lost time.</p>



<p>It's even more distressing to consider that half of individuals battling anxiety and/or depression feel they've lost years of their life to these challenges. The fact that 12% report losing entire decades emphasizes the profound and far-reaching consequences of <a href="https://www.earth.com/news/supportive-adults-help-protect-children-from-mental-health-issues/" target="_blank" rel="noreferrer noopener">mental</a> health struggles. </p>



<p>These are not just numbers; they represent stolen moments, missed experiences, and the immense weight of mental illness over a lifetime.</p>



<h2 class="wp-block-heading" id="h-what-does-losing-time-to-mental-health-look-like">What does losing time to mental health look like?</h2>



<p>The concept of "lost time" might seem abstract, but the consequences are painfully real. For those struggling with mental health, this translates into a devastating array of missed experiences:</p>



<h3 class="wp-block-heading" id="h-missed-milestones">Missed milestones</h3>



<p>Over half of individuals with anxiety and/or depression report the heartbreak of missing out on major life events. These are moments meant for celebration – weddings, graduations, the birth of children – yet mental health struggles cast a dark shadow over what should be joyous occasions.</p>



<h3 class="wp-block-heading" id="h-special-moments">Special moments</h3>



<p>It's not just about absence. Even when physically present at important gatherings, a staggering 71% of those surveyed say that mental health prevents them from truly being there. Imagine being surrounded by loved ones yet feeling disconnected, unable to fully participate in the shared experience.</p>



<h3 class="wp-block-heading" id="h-mental-health-s-stolen-joyful-times">Mental health's stolen joyful times</h3>



<p>Nearly 8 in 10 people admit that within the past year alone, their mental health has robbed them of simple pleasures. This could mean struggling to find enjoyment in hobbies, outings with friends, or even moments of everyday relaxation.</p>



<p>“For a patient who is struggling, time ticks a lot slower than it does for the rest of us,” said Debbie Thomas, a psychiatric nurse practitioner in Louisville, Kentucky. “One of my patients told me that, when they woke up in the morning, they counted how many hours before they could go back to bed. That’s pretty telling when someone is in the depths of depression and anxiety to that degree.”&nbsp;&nbsp;</p>



<h2 class="wp-block-heading" id="h-frustration-and-regret-of-lost-time-to-mental-health">Frustration and regret of lost time to mental health</h2>



<p>The pain of missing out on life due to mental health issues goes far deeper than the events themselves. The aftermath holds its own set of agonizing emotions:</p>



<h3 class="wp-block-heading" id="h-exhaustion">Exhaustion</h3>



<p>For 60%, depressive episodes leave them feeling utterly depleted, as if every ounce of energy has been wrung out of them. This isn't just tiredness; it's a profound physical and emotional drain.</p>



<h3 class="wp-block-heading" id="h-disorientation">Disorientation </h3>



<p>Half of respondents describe the end of a down period as disorienting – like waking from a confusing, hazy fog. This speaks to the distorting effect mental illness has on one's perception of reality and sense of self.</p>



<h3 class="wp-block-heading" id="h-disappointment">Disappointment</h3>



<p>A significant 47% struggle with deep sadness and frustration over the missed opportunities. This lingering disappointment underscores the realization that while time moves forward, the moments lost to mental health struggles can never be recovered.</p>



<p>“Patients who have lost time due to depressive episodes or periods of anxiety often feel a sense of loss, which further complicates their mental health situation,” said Sharon Philbin, an advanced practice registered nurse in Pawtucket, Rhode Island,. “Many of my patients say they are thankful they feel better, but they worry that it will happen again.”</p>



<h2 class="wp-block-heading" id="h-prolonged-treatment-time-of-mental-health">Prolonged treatment time of mental health</h2>



<p>Sadly, one out of every three respondents with anxiety and/or depression feels that they've missed out on things due to ineffective mental health treatments. Navigating the world of psychiatric medication can be tough. </p>



<p>The typical approach often involves months or even years of trial and error as doctors and patients struggle to find the right medication and dosage. </p>



<h2 class="wp-block-heading" id="h-prioritize-your-mental-health-with-time">Prioritize your mental health with time</h2>



<p>Taking care of your mental health is essential for both your well-being and your ability to lead a fulfilling life. Here are strategies to help manage and improve your mental health:</p>



<h3 class="wp-block-heading">Stay active</h3>



<p>Physical activity isn't just good for the body; it also has a profound impact on our mental health. Exercise releases endorphins, chemicals in your brain that act as natural painkillers and mood elevators. It also helps regulate sleep, which can greatly improve <a href="https://www.earth.com/news/natural-biodiversity-areas-have-greater-mental-health-impact/" target="_blank" rel="noreferrer noopener">mood</a> and decrease stress. Aim for at least 30 minutes of moderate exercise most days of the week.</p>



<h3 class="wp-block-heading">Eat well</h3>



<p>Nutrition plays a crucial role in brain health. Eating a diet rich in antioxidants, vitamins, and minerals supports brain function and can ward off anxiety and depression. Focus on incorporating plenty of fruits, vegetables, lean protein, and whole grains into your diet. Omega-3 fatty acids, found in fish like salmon, have been shown to reduce symptoms of depression and anxiety.</p>



<h3 class="wp-block-heading">Get enough sleep</h3>



<p>Sleep and mental health are closely connected. Lack of sleep can exacerbate stress, anxiety, and depression. Try to maintain a regular sleep schedule—going to bed and waking up at the same time every day. Ensure your bedroom is conducive to sleep: quiet, dark, and cool, and free from screens and distractions.</p>



<h3 class="wp-block-heading">Connect with others</h3>



<p><a href="https://www.earth.com/news/spending-less-time-on-social-media-improves-your-mental-health/" target="_blank" rel="noreferrer noopener">Social</a> interaction is a fundamental human need that helps ward off loneliness and depression. Maintain strong relationships with friends and family who can provide support and understanding. Activities like joining clubs or groups, volunteering, or attending community events can also provide valuable social interaction.</p>



<h3 class="wp-block-heading">Manage stress</h3>



<p>Chronic stress is detrimental to mental health. Managing stress through <a href="https://www.earth.com/news/using-apps-to-practice-mindfulness-improves-mental-health-of-children/" target="_blank" rel="noreferrer noopener">mindfulness</a>, meditation, yoga, or deep-breathing exercises can significantly reduce your anxiety and improve your emotional well-being. Regular practice can help you stay calm and better equipped to handle life's challenges.</p>



<h3 class="wp-block-heading">Avoid Alcohol and drugs</h3>



<p>While you might feel that alcohol or drugs lessen stress in the short term, they often worsen symptoms of anxiety and depression in the long run. If you're struggling with substance use, seek professional help to develop healthier coping mechanisms.</p>



<h3 class="wp-block-heading">Set goals and priorities</h3>



<p>Determine what you want to achieve personally and professionally and set realistic goals to help guide you. Setting and achieving goals provides a sense of purpose and control, which can greatly improve your mental health.</p>



<h3 class="wp-block-heading">Take breaks</h3>



<p>In times of stress, taking a step back to simply breathe and relax can be incredibly helpful. Whether it’s stepping outside, taking a day off to unwind, or simply setting aside time for hobbies you enjoy, breaks can significantly restore your mental energy.</p>



<h3 class="wp-block-heading">Practice gratitude</h3>



<p>Recognizing and appreciating the positives in your life can shift your mindset from one of scarcity to one of abundance, which can decrease anxiety and boost your mood. Consider keeping a gratitude journal, where you regularly write down things you're grateful for, to help maintain a positive frame of mind.</p>



<h3 class="wp-block-heading" id="h-get-help-for-mental-health-time-loss">Get help for mental health time loss</h3>



<p>There's no substitute for professional help when it comes to treating mental illness. A mental health professional can provide a diagnosis, offer treatment, and help you develop strategies to cope with symptoms. Don’t hesitate to seek help if you feel overwhelmed or unable to cope.</p>



<ul>
<li><strong>Talk to your doctor:</strong>&nbsp;Discuss your symptoms and discuss medication options. Ask about whether genetic testing to diagnose mental health issues might be right for you.</li>



<li><strong>Seek therapy:</strong>&nbsp;A qualified therapist can offer valuable guidance, coping strategies, and support on your mental health journey.</li>



<li><strong>Support resources:</strong>&nbsp;Organizations like the National Alliance on Mental Illness (<a href="https://www.nami.org/" target="_blank" rel="noreferrer noopener">NAMI</a>) offer education, support groups, and helplines.</li>
</ul>



<p>The GeneSight Mental Health Monitor is a survey conducted by ACUPOLL Precision Research, Inc This study was commissioned by Myriad Genetics, a leader in genetic testing and precision medicine. Their GeneSight Psychotropic test offers insights into how an individual's genes may affect their response to various mental health medications.</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>

<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>
