In the midst of our busy lives, those seemingly insignificant everyday experiences - like booking a flight home for Thanksgiving or writing a thank-you note - may feel less meaningful.



But according to Erin Westgate, assistant professor of psychology at the University of Florida, these experiences carry more value than we attribute them.



<h2 class="wp-block-heading" id="h-purpose-behind-the-research">Purpose behind the research</h2>



Alongside her team at the <a href="https://socialcognition.psych.ufl.edu" target="_blank" rel="noreferrer noopener">Florida Social Cognition and Emotion Lab</a>, Westgate recently secured a grant from the National Science Foundation.



The researchers intended to examine why people underestimate the significance of future life <a href="https://www.earth.com/news/facial-expressions-arent-enough-to-understand-human-emotions/" target="_blank" rel="noreferrer noopener">experiences</a>. The spark for this exploration ignited during Westgate's school days.



“This started a long time ago when I was in grad school where I was talking to another student who asked me if we know how meaningful events will be in the future,” Westgate said.



<h2 class="wp-block-heading" id="h-meaningful-experience-of-thanksgiving">Meaningful experience of Thanksgiving</h2>



The question prompted an interesting study involving <a href="https://www.virginia.edu" target="_blank" rel="noreferrer noopener">University of Virginia</a> undergraduates. The students were asked about their expectations of the upcoming Thanksgiving holiday's meaningfulness and their thoughts afterward. 



“Surely people know how significant Thanksgiving will be, right? It’s the poster child for gratitude and meaning,” Westgate said.



Much to Westgate's surprise, the students extensively misjudged their <a href="https://www.earth.com/news/social-media-likes-have-a-strong-emotional-effect-on-young-people/" target="_blank" rel="noreferrer noopener">feelings</a> about the holiday.



<h2 class="wp-block-heading" id="h-missing-out-on-meaningful-experiences">Missing out on meaningful experiences </h2>



Fast forward to the pandemic-ridden 2020. Westgate revisited her initial findings, asking, “We found it once, but can we find it again?”



With a larger sample of University of Florida undergraduates, the results echoed the first study. People chronically underestimated the value of their Thanksgiving holiday.



“We want to live meaningful lives, we want to do meaningful things and so if we are not realizing that an experience is going to be meaningful, we may be less likely to do it and miss out on these potential sources of meaning in our own lives,” Westgate said.



<h2 class="wp-block-heading" id="h-decision-factors-in-meaningful-experiences">Decision factors in meaningful experiences</h2>



The research indicated a key factor in decision-making - anticipated <a href="https://www.earth.com/news/mixed-emotions-linked-to-unique-brain-activity/" target="_blank" rel="noreferrer noopener">feelings</a>.



Whether it's a life-altering decision like a career choice or a family start, or a minor one like attending a holiday event, our decisions lean towards promoting a sense of purpose and fulfillment.



Over the course of a three-year study, Westgate aims to condense the reasons behind our underestimation of experiences - from our career choices to the seemingly mundane task of writing thank-you notes.



The research considers both positive and negative experiences, including the acceptance or rejection of medical school applications.



<h2 class="wp-block-heading" id="h-making-sense-of-events">Making sense of events</h2>



The study also explores personal growth experiences that entail discomfort, leading to avoiding certain decisions out of fear.



Still, these very decisions could play an instrumental role in developing resilience and yielding deep satisfaction.



“We don’t make sense of events until they actually happen. We don’t process events until we need to, when they actually happen and not before,” said Westgate. Jumping the gun might lead us to underestimate the potential meaning of certain events.



<h2 class="wp-block-heading" id="h-seeking-solutions-for-underestimation">Seeking solutions for underestimation</h2>



The research aims to go beyond merely identifying problems; it seeks actionable solutions. Many of us often overlook the true value of meaningful experiences. 



This oversight can lead to a less fulfilling life, as we fail to appreciate the depth and significance of our everyday moments. By delving into the reasons behind this underestimation, Westgate’s work strives to illuminate the cognitive biases and misconceptions that cloud our perception of meaning.



Understanding the root of these misconceptions is crucial. It involves exploring psychological patterns and societal influences that lead individuals to undervalue their <a href="https://www.earth.com/news/emotional-intelligence-may-be-secret-to-academic-success/" target="_blank" rel="noreferrer noopener">experiences</a>. 



By identifying these patterns, the research can offer strategies to shift our perspectives and encourage a deeper appreciation of our lives. This shift could not only enhance individual well-being but also promote a more profound connection with others and the world around us.



<h2 class="wp-block-heading" id="h-harnessing-meaningful-experiences-in-daily-life">Harnessing meaningful experiences in daily life</h2>



The findings suggest that by becoming more aware of our tendency to underestimate the meaningfulness of experiences, individuals can purposefully cultivate more fulfilling daily lives.



Simple changes, such as being more present in the moment, keeping a gratitude journal, or actively reflecting on past experiences, can enhance appreciation for life's ordinary events. 



These practices can help individuals recognize the intrinsic value in seemingly minor experiences, thereby enriching personal happiness and well-being.



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



The research carries significant implications for psychological interventions aiming to promote mental well-being. Interventions could focus on enhancing awareness of meaningful experiences and encouraging individuals to engage in activities that nurture a sense of purpose.



By integrating these insights into therapy and counseling, mental health practitioners can better support clients in recognizing and capitalizing on the meaningful dimensions of their lives, potentially improving mental resilience and overall life satisfaction.



“Sometimes we go into a project, and we know what we are going to find. This is one of those projects that surprised us,” concluded Westgate.

Pollinator,Honey,Bee,Apis,Mellifera,With,Full,Loaded,Baskets,Pockets

A new study published by <a href="https://www.aaas.org/">AAAS</a> has revealed how the global <a href="https://www.earth.com/news/cactus-pears-show-great-potential-for-sustainable-food-and-fuel/">food</a> trade is reliant on biodiversity and wild pollinators. The researchers found that developed countries are especially dependent on imported pollinated crops, while the countries that export these crops are primarily responsible for declines in pollinators.

A new understanding of the "virtual" exchange of pollinator services in the global food trade could support new policies to preserve crop diversity and tackle biodiversity loss. 

In a globalized world, human food consumption relies heavily on the trade of crops, as well as the intense use of water and land resources. 

Bees, flies, beetles, and other pollinators - along with the invaluable services they provide - are critically important to agriculture. A previous study estimated that 35 percent of crop production and 75 percent of crops require pollination services. 

The primary cause of environmental degradation is human disturbance. As the natural environment is compromised by human activities, wild pollinators are increasingly exposed to habitat loss, pesticides and other chemicals, invasive pests, and diseases. As a result, pollinating species are in a global state of decline.

Scientists are working to identify regions where protecting biodiversity will best preserve pollinators and crop production. 

A team of experts led by Felipe da Silva set out to study pollination as a traded resource based on the concept of "virtual resource flow." 

To investigate how wild pollinator services in crop-exporting countries transfer to international markets, the researchers analyzed data on 55 pollinator-dependent crops from 2001 to 2015. The experts compared how developing and developed countries rely on pollination services. 

The study revealed that developed countries rely heavily on imported, pollinator-dependent crops to sustain their food consumption, which means that these countries "virtually" import pollination services from other nations that depend on biodiversity to sustain pollination. 

In addition, countries that exported the most pollinator-dependent crops were linked to the fastest rates of cropland expansion, which is a major driver of pollinator and biodiversity decline. 

The study is published in the journal <a href="https://advances.sciencemag.org/">Science Advances</a>.

Reductions in air pollution could actually boost global warming without a substantial cut in carbon dioxide emissions. Computer modeling experiments from <a href="https://www.kyushu-u.ac.jp/en/">Kyushu University</a> have revealed that surface air temperature will increase without the cooling effect of sulfate aerosols, unless <a href="https://www.earth.com/news/subsea-permafrost-could-unleash-catastrophic-co2-emissions/">CO2</a> levels are simultaneously reduced. 

Worldwide, nations are scrambling to limit CO2 emissions in an effort to mitigate global warming. The new study suggests that without major cuts to greenhouse gas emissions, reductions in air pollution will make it difficult to defeat rising temperatures.

"Air pollution causes an estimated seven million premature deaths per year worldwide, so action is essential, especially in emerging and developing countries, which tend to be most affected," said study co-author Professor Toshihiko Takemura.

"However, reductions in air pollutants must come hand in hand with reductions in greenhouse gases to avoid accelerating global warming."

The study shows that the long-term effects of reductions in pollutants known as sulfate aerosols will cause further increases in surface air temperature at current and increased carbon dioxide levels. This is due to an overall cooling effect that is produced by the light-scattering particles.

To investigate how these aerosols--small particles of sulfur-containing compounds influence the climate, Professor Takemura used a combination of models known as MIROC-SPRINTARS.

While MIROC accounts for many key aspects of the atmosphere, SPRINTARS predicts the mixing of aerosols in the atmosphere. By combining the two models, climate projections can include effects from the scattering and absorption of light by aerosols, as well as the interaction of aerosols with clouds.

The immediate changes to the atmosphere with reduced sulfate aerosols were found to be the same regardless of CO2 levels. However, when looking at changes in the climate and surface temperatures over longer time scales, Professor Takemura found that not only does the surface air temperature increase with a reduction in sulfate aerosols - but this increase is even larger with rising levels of carbon dioxide.

"Although the fast response is similar for both situations, long-term changes caused by more slowly responding factors related to interactions with the oceans and subsequent changes, such as in clouds and precipitation, eventually leads to a bigger temperature increase," explained Professor Takemura.

"Thus, global warming will accelerate unless increases in greenhouse gas concentrations are suppressed as air pollution control measures decrease sulfate aerosol concentrations, further emphasizing the urgency for reducing carbon dioxide in the atmosphere."

The study is published in the journal <a href="https://www.nature.com/srep/">Scientific Reports</a>.

A new study from the <a href="https://www.sheffield.ac.uk/">University of Sheffield</a> has revealed that legume trees are key to the restoration of tropical forests. The experts have found that trees in the legume family release vital minerals from the <a href="https://www.earth.com/news/fruit-eating-mammals-fertilize-the-soil-in-tropical-forests/">soil</a> and share them with neighboring trees. 

"Our research shows that legume trees not only provide valuable nitrogen through their symbioses with bacteria that live in their roots, but interact with free-living soil bacteria allowing nutrients to be chemically released," explained study lead author Dr. Dimitat Epihov.

"We discovered the abundance of a novel group of acid-loving bacteria, key in liberating minerals locked in iron minerals beneath legume trees, and that those benefits are passed on to nearby trees."

The findings are shedding new light on the role legume trees play in safeguarding the function of tropical forests. The research may also help to inform land managers and policy makers on how best to approach reforestation on degraded land.

The researchers discovered that legume trees overcome the challenge of growing on nutrient-poor soils by accelerating weathering processes. The trees acidify the soil and adjust its carbon to nitrogen ratio, ultimately providing easier access to nutrients.

The microbial changes in the soil favor a type of bacteria that breaks down iron, which releases iron-bound minerals critical to tree growth.

Legume trees are also particularly important in the process of forest recovery because they are able to supply fresh nitrogen into soils. This nitrogen gets broken down by bacteria and utilized by trees locally. 

Study co-author Professor David Beerling is the director of the University of Sheffield's Leverhulme Centre for Climate Change Mitigation.

"By using advanced genomic sequencing techniques we have addressed a long standing puzzle of how fast growing trees access sufficient nutrients to support their growth from nutrient-poor soils," said Professor Beerling.

"The answer, it turns out, is to exploit specialised consortia of soil microbes whose metabolism allows them to efficiently break down rocks and extract nutrients they contain."

The study is published in the journal <a href="https://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

Wild,Peach,Fruits,In,Early,Summer

In a new study led by the <a href="https://btiscience.org/">Boyce Thompson Institute</a>, scientists have identified genes that could help domesticated peaches become more resistant to the pressures associated with climate change. 

"Our study provides many candidate genes, showing how the peach has adapted to all kinds of environmental stresses and stimuli," said study co-lead author Professor Zhangjun Fei. 

"Breeders can use this information to develop more resilient domesticated peach trees that cope better with temperature extremes, drought and other harsh, changing conditions imposed by climate change."

The researchers analyzed DNA sequences in wild peaches that have adapted over a long time to specific local conditions across seven different regions in China. The experts identified genes that provide tolerance to extreme conditions, such as drought and ultraviolet radiation.

There is an urgent need to make food crops more resistant to climate change, which is causing many plants to become less productive. 

While many studies have identified genes that enable rice and other food crops to adapt to climate stress, few studies have been focused on major fruit crops. The domesticated peach, Prunus persica, has a global yield of 24.5 million tons per year.

According to the researchers, many of domesticated peach's adaptation genes have been lost as humans bred the plant to focus on traits such as flavor. Wild varieties contain the genetic diversity that is needed to make domesticated peaches more resilient. 

The study was focused on 263 types of wild peaches and landraces, including 218 from the National Peach Germplasm Repository of China and 45 from the Tibetan Plateau. Overall, the team identified more than 2,700 areas of the genome that are linked to 51 local climate factors.

For example, peaches from a region with extremely low winter temperatures had a genetic variant that provides resistance to cold. Wild peaches from a very arid region were found to have multiple genetic variants that regulate their response to drought.

"When a fruiting plant like peach is growing under a stressful condition like drought, its fruit gets sweeter," said Professor Fei. "In this study, we have found the direct genetic link between drought and the sugar content of peach."

Among peach trees from the Tibetan Plateau, the team identified a variant that protects the fruit from the intense UV-B radiation that is found in high altitudes.

"Overall, the genetic information we found could help people breed peach trees that grow in many different and harsh environments, expanding peach's geographic range to new regions," said Professor Fei. 

"Breeders could develop cultivars that thrive on otherwise unused land, bolstering the local economy and bringing more good food to local markets."

The study is published in the journal <a href="https://genome.cshlp.org/">Genome Research</a>.

The economic benefits of protecting nature are greater than the benefits of exploiting it, according to new research from the <a href="https://www.cam.ac.uk/">University of Cambridge</a>. The study is the largest of its kind to compare the value of conserving natural sites to potential economic gains from converting them for human use.

"Current rates of habitat conversion are driving a species extinction crisis unlike anything in human history," said study senior author Professor Andrew Balmford.

"Even if you are only interested in dollars and cents, we can see that conserving and restoring nature is now very often the best bet for human prosperity. The findings echo at an operational scale the overall conclusions drawn by the Dasgupta Review."

The team examined dozens of sites across six continents. The results of the analysis have been published just weeks after a landmark report by Cambridge Professor Partha Dasgupta called for the value of biodiversity to be placed at the heart of global economics.

The experts calculated the monetary worth of each site's "ecosystem services," including carbon storage and flood protection. They also measured the value of each site by estimating the potential profits from converting it for production of goods such as crops and timber.

"Stemming biodiversity loss is a vital goal in itself, but nature also fundamentally underpins human well-being," said study lead author Dr. Richard Bradbury. "We need nature-related financial disclosure, and incentives for nature-focused land management, whether through taxes and regulation or subsidies for ecosystem services."

The study revealed that one major economic benefit of natural habitats is driven by their ability to help lower greenhouse gas emissions through processes like carbon sequestration.

Each ton of carbon carries a cost of at least $31 to global society. Based on this rate, which many scientists consider to be too conservative, more than 70 percent of the sites examined for the study have greater monetary value as natural habitats.

Even if the societal cost of carbon is removed completely from their calculations, the researchers found that almost half of the 24 sites were still worth more in their natural state.

"People mainly exploit nature to derive financial benefits. Yet in almost half of the cases we studied, human-induced exploitation subtracted rather than increased economic value," said study co-author Dr. Kelvin Peh of the University of Southampton.

Ten years ago, the scientists designed the Toolkit for Ecosystem Service Site-based Assessment (TESSA), which enables users to measure and assign a monetary value to services provided by a natural site. The new study is focused on results from 62 applications of TESSA around the world, which were mostly either forest or wetland. 

In one case, the scientists discovered that if Nepal's Shivapuri-Nagarjun National Park lost its protection and was converted from forest to farmland, it would cut carbon storage by 60 percent and reduce water quality by 88 percent. Combined with other costs, the conversion of this national park would produce a deficit of $11 million per year.

According to study co-author Anne-Sophie Pellier from BirdLife International, the results support the idea that conserving and restoring key biodiversity areas is not only important for safeguarding our natural heritage, but also for providing wider economic benefits to society.

The study is published in the journal <a href="https://www.nature.com/natsustain/">Nature Sustainability</a>.

Comets like Catalina may have delivered carbon to Earth, Mars, and other <a href="https://www.earth.com/news/meteors-may-transfer-life-from-earth-to-other-planets/">planets</a> during the early formation of the solar system, according to a new report from NASA.

In early 2016, Comet Catalina was briefly visible near the Big Dipper as it flew past Earth. The comet had made a long journey from the Oort cloud, a region at the very edge of the solar system where comets are born.

Images of Catalina were captured by the Stratospheric Observatory for Infrared Astronomy (SOFIA), a joint project of NASA and the German Aerospace Center. 

SOFIA, which is essentially a telescope mounted on an airplane, contains unique infrared instruments. One of these instruments detected carbon within the dusty glow of the comet’s tail.

“Carbon is key to learning about the origins of life,” said study lead author Charles Woodward, an astrophysicist and professor at the University of Minnesota. “We’re still not sure if Earth could have trapped enough carbon on its own during its formation, so carbon-rich comets could have been an important source delivering this essential element that led to life as we know it.”

The researchers explained that Comet Catalina and other comets are effectively frozen in time, and are relatively unaltered when we get a glimpse of them. This offers scientists with rare opportunities to study the early solar system in which the comets originated. 

The research suggests that Comet Catalina formed in the outer regions of the primordial solar system, which held a reservoir of carbon.

NASA reports that while carbon is a key ingredient of life, early Earth and other terrestrial planets of the inner solar system were so hot during their formation that elements like carbon were lost or depleted. 

“All terrestrial worlds are subject to impacts by comets and other small bodies, which carry carbon and other elements,” said Woodward. “We are getting closer to understanding exactly how these impacts on early planets may have catalyzed life.”

To further investigate the theory that early comets delivered carbon to Earth and other young planets, additional observations are needed to learn if there are many other carbon-rich comets in the Oort Cloud. Such observations could help clarify whether life-supporting elements were transported to the terrestrial planet on icy comets. 

The research is published in the <a href="https://iopscience.iop.org/journal/2632-3338">Planetary Science Journal</a>.

For the first time, scientists have discovered the remains of a dinosaur sitting on a nest of <a href="https://www.earth.com/news/drosophila-flies-prefer-to-lay-their-eggs-in-untouched-fruit/">eggs</a> with fossilized babies, according to a new study published by <a href="https://engine.scichina.com/publisher/scp">Science China Press</a>.

The specimen is an oviraptorosaur, a bird-like theropod dinosaur that thrived during the Cretaceous Period, commonly known as the "Age of Dinosaurs."

The dinosaur was recovered in Ganzhou City in southern China's Jiangxi Province, preserved in Cretaceous-aged rocks that date back as far as 70 million years. 

"Dinosaurs preserved on their nests are rare, and so are fossil embryos," said study co-author Dr. Shundong Bi. "This is the first time a non-avian dinosaur has been found, sitting on a nest of eggs that preserve embryos, in a single spectacular specimen."

The fossil contains the incomplete skeleton of a large oviraptorid crouched in a bird-like brooding posture over a clutch of two dozen eggs. At least seven of these eggs preserve bones or partial skeletons of unhatched embryos inside. 

The close proximity of the adult to the eggs, as well as the late stage of development of the embryos, indicates that the dinosaur died in the act of incubating its nest.

Prior to this study, a few other oviraptorid skeletons have been found sitting on nests. The analyses of those fossils concluded that the animals were simply laying eggs or guarding the nests. 

However, the new study suggests that oviraptorosaurs incubated their eggs to keep them at the proper temperature like modern birds. 

"This kind of discovery, in essence fossilized behavior, is the rarest of the rare in dinosaurs," explained Dr. Matthew C. Lamanna. "Though a few adult oviraptorids have been found on nests of their eggs before, no embryos have ever been found inside those eggs." 

"In the new specimen, the babies were almost ready to hatch, which tells us beyond a doubt that this oviraptorid had tended its nest for quite a long time. This dinosaur was a caring parent that ultimately gave its life while nurturing its young."

The researchers conducted oxygen isotope analyses on the eggs, which revealed that they had been incubated at high temperatures. This supports the theory that the adult dinosaur died in the act of brooding its nest. 

While all of the embryos were well-developed, some were more mature than others, suggesting that oviraptorid eggs of the same clutch may have hatched at slightly different times. Asynchronous hatching appears to have evolved independently in oviraptorosaurs and some modern birds.

"It's extraordinary to think how much biological information is captured in just this single fossil," said Dr. Xing Xu. "We're going to be learning from this specimen for many years to come."

The study is published in the journal <a href="https://www.journals.elsevier.com/science-bulletin">Science Bulletin</a>.

An alarming number of Asian bamboo longhorn beetles have been emerging across Europe over the last century, according to new research from <a href="https://pensoft.net/">Pensoft Publishers</a>. The study, which was based on documentation by citizen scientists, demonstrates the importance of involving the public in <a href="https://www.earth.com/news/recent-genetic-connectivity-found-among-chimpanzee-subspecies/">species</a> monitoring.

The experts noted that invasive species represent one of the major challenges of a globalized world. 

"These species, while often barely recognized, may represent severe economic and ecological threats (e.g. as agricultural pests, ecological competitors or predators of native species)," wrote the researchers. 

"However, despite their potentially high importance, surveying non-native species is still only performed for a limited number of highly invasive species, as it is time consuming and expensive."

As an alternative to costly research projects, the general public can be included in surveying activities through citizen science initiatives and online platforms.

"While large invasive species, such as mammals, birds and fish, are detected more easily, smaller arthropod species often remain unspotted for some time after their introduction. Nevertheless, arthropods, and especially insects have high invasion potential and can often be detrimental pests," wrote the study authors.

"Insects are frequently transported with raw materials, and agricultural products, or living plants and plant material. One of the groups specifically commonly introduced with plants and wood are the longhorn wood boring beetles of the family Cerambycidae."

The Asian bamboo longhorn beetle feeds on a variety of plants, but prefers bamboo. The species has been continuously expanding its distribution through the international trade of bamboo, as the insects "travel" along with the wood. The beetle's first appearance in England was documented in 1924.

More recently, students at the University of Hamburg were conducting a fieldwork study - held within the city due to COVID-19 restrictions - when they stumbled upon an Asian bamboo longhorn beetle.

Further investigation revealed that there were even more recent sightings of the beetles that had been recorded across different citizen science platforms, such as iNaturalist and iRecord.

The researchers contacted the citizen scientists, who provided additional collection details and images. Based on this information, the researchers formally confirmed the presence of the Asian bamboo longhorn beetle in Belgium and the Netherlands. 

Overall, the experts identified thirteen new introductions of the species in Europe. This translates to a 42 percent increase of Asian bamboo longhorn beetle records in Europe.

"In light of the warming climate and a growing abundance of ornamental bamboo plants in Europe, the beetle might get permanently established. Not only could it become a garden pest, but it could also incur significant costs to the bamboo-processing industry," said study lead author Dr. Matthias Seidel.

Now that the researchers have witnessed the potential of citizen science for bridging the gaps in invasive species monitoring, they propose that specialized platforms could be established to speed up the surveying process. The platforms would be designed to familiarize citizen scientists with non-native species of interest, while providing them with more sophisticated reporting tools. 

"In order to use the power of citizen science for the monitoring of non-native species more effectively, two approaches may be specifically promising," explained the study authors.

"On the one hand, specialized platforms introducing non-native species of interest to the general public and providing reporting tools may increase public awareness and also recording activities for these taxa." 

"On the other hand, drawing records of specific non-native species of interest, which are flagged and regularly exported from other citizen science databases and platforms may help to provide a better overview of distributions of these taxa."

The research is published in the journal <a href="https://biorisk.pensoft.net/">BioRisk</a>.

Just two servings of fish per week can help prevent recurrent cardiovascular events, according to new research from <a href="https://www.mcmaster.ca/">McMaster University</a>. The experts analyzed multiple large studies involving participants from more than 60 countries. 

The study revealed that eating oily fish on a regular basis substantially lowers the likelihood of cardiovascular events such as heart attack or <a href="https://www.earth.com/news/many-young-adults-do-not-know-common-stroke-symptoms/">stroke</a> among high-risk individuals.

The critical compound found in fish is omega-3 fatty acid, which is a type of essential fat that the body cannot make on its own. Omega-3 fatty acids are strongly associated with improved heart health. 

The researchers found that, among high-risk individuals, two servings of omega-3-rich fish each week lowered the threat of major cardiovascular events by one-sixth.

"There is a significant protective benefit of fish consumption in people with cardiovascular disease," said study co-lead author Professor Andrew Mente.

"This study has important implications for guidelines on fish intake globally. It indicates that increasing fish consumption and particularly oily fish in vascular patients may produce a modest cardiovascular benefit."

According to Mente, people at low risk for cardiovascular disease can still enjoy modest protection from CVD by eating fish rich in omega-3, but the health benefits were less pronounced than those high-risk individuals.

The investigation was based on data from nearly 192,000 people in four studies, including about 52,000 with cardiovascular disease. It is the first study of its kind to be conducted on all five continents. 

"This is by far the most diverse study of fish intake and health outcomes in the world and the only one with sufficient numbers with representation from high, middle and low income countries from all inhabited continents of the world," said study co-lead author Dr. Salim Yusuf.

The study is published in the journal <a href="https://jamanetwork.com/journals/jamainternalmedicine">JAMA Internal Medicine</a>.

Summer could drag out for nearly six months in the Northern Hemisphere by the end of this century, according to a new study published by the <a href="https://www.agu.org/">American Geophysical Union</a>. The experts report that without efforts to mitigate <a href="https://www.earth.com/news/humans-can-overcome-climate-change-by-being-flexible/">climate</a> change, a persistent summer season could have far-reaching impacts on agriculture, human health, and the environment.

Beginning in the 1950s, the four seasons arrived in a predictable and fairly even pattern across the Northern Hemisphere. But now, climate change is causing the seasons to become more irregular. 

The research shows that the unpredictable lengths and start dates of the seasons will become even more extreme in the coming decades under a business-as-usual emissions scenario.

Study lead author Yuping Guan is a physical oceanographer at the State Key Laboratory of Tropical Oceanography, South China Sea Institute of Oceanology, and the Chinese Academy of Sciences.

"Summers are getting longer and hotter while winters shorter and warmer due to global warming," said Guan. He was inspired to investigate changes to the seasonal cycle while working with undergraduate student and study co-author Jiamin Wang. 

To measure changes in the length and onset of four seasons in the Northern Hemisphere, the researchers analyzed historical daily climate data from 1952 to 2011.

The team defined the start of summer as the onset of temperatures in the hottest 25 percent during that time period, while winter began with temperatures in the coldest 25 percent. Next, the experts used climate change models to predict how seasons will shift in the future.

The analysis revealed that during the study period, summer grew from 78 to 95 days, while winter shrank from 76 to 73 days. Spring decreased from 124 to 115 days, and autumn dropped from 87 to 82 days. Overall, spring and summer arrived earlier, while autumn and winter started later. 

The greatest changes in seasonal changes took place in the Mediterranean region and across the Tibetan Plateau. The researchers predict that without climate change mitigation efforts, winter will last less than two months, and the transitional spring and autumn seasons will continue to shrink throughout the remainder of this century.  

"Numerous studies have already shown that the changing seasons cause significant environmental and health risks," said Guan. For example, birds are shifting their migration patterns and plants are flowering at different times, creating potential mismatches between animals and their food sources. Seasonal changes can also be very damaging to crops and budding plants when false springs or late snowstorms occur. 

Furthermore, prolonged warm weather extends pollen and allergy season, as well as the length of time that disease-carrying mosquitoes persist and move northward.

Congwen Zhu is a monsoon researcher at the State Key Laboratory of Severe Weather and Institute of Climate System, who was not involved in the study. He noted that a shift in the seasons could result in more severe weather events

"A hotter and longer summer will suffer more frequent and intensified high-temperature events - heatwaves and wildfires," said Zhu. Additionally, he explained, warmer and shorter winters may cause instability that leads to cold surges and winter storms, much like the recent snowstorms in Texas and Israel.

"This is a good overarching starting point for understanding the implications of seasonal change," said Scott Sheridan, a climate scientist at Kent State University. "I think realizing that these changes will force potentially dramatic shifts in seasons probably has a much greater impact on how you perceive what climate change is doing."

The study is published in the journal <a href="https://agupubs.onlinelibrary.wiley.com/journal/19448007">Geophysical Research Letters</a>.

Black,Tea,,Herbal,Tea

In a breakthrough study from <a href="https://uci.edu/">UC Irvine</a>, researchers have uncovered an explanation for the antihypertensive effects of tea. The experts report that both green and black tea contain compounds that relax the blood vessels by activating ion channel proteins in the blood vessel wall. 

The discovery was made in the lab of Dr. Geoffrey Abbott, a professor in the Department of Physiology and Biophysics at the UCI School of Medicine. The findings may ultimately lead to the development of new medications for lowering blood pressure.

The researchers identified two flavonoid compounds that each activate a specific type of ion channel protein named KCNQ5. This protein allows potassium ions to diffuse out of cells to reduce cellular excitability. 

The team predicted that since KCNQ5 is found in the smooth muscle that lines blood vessels, its activation by tea catechins would also relax blood vessels.

"We found by using computer modeling and mutagenesis studies that specific catechins bind to the foot of the voltage sensor, which is the part of KCNQ5 that allows the channel to open in response to cellular excitation. This binding allows the channel to open much more easily and earlier in the cellular excitation process," explained Dr. Abbott.

Previous studies have demonstrated that consumption of green or black tea can reduce blood pressure by a small but consistent amount, and catechins were found to contribute to this effect. 

The research has major implications for improving human health. Hypertension is a very common condition that is considered to be the number one modifiable risk factor for cardiovascular disease and premature mortality, 

Each day worldwide, more than two billion cups of tea are consumed, which is second only to water. The three most popular caffeinated teas - green, oolong, and black - are all produced from the leaves of the evergreen species Camellia sinensis.

In the UK and the United States, black tea is commonly mixed with milk. The researchers found that when black tea was directly applied to cells containing the KCNQ5 channel, the addition of milk prevented its activation. However, Dr. Abbott explained that milk is not likely to interfere with the antihypertensive effects of black tea.

"We don't believe this means one needs to avoid milk when drinking tea to take advantage of the beneficial properties of tea. We are confident that the environment in the human stomach will separate the catechins from the proteins and other molecules in milk that would otherwise block catechins' beneficial effects."

"Regardless of whether tea is consumed iced or hot, this temperature is achieved after tea is drunk, as human body temperature is about 37 degrees Celsius," explained Dr. Abbott. "Thus, simply by drinking tea we activate its beneficial, antihypertensive properties."

The study is published in the journal <a href="https://www.karger.com/CPB">Cellular Physiology and Biochemistry</a>.

Breakthrough study explains why tea reduces hypertension

In a breakthrough study from UC Irvine, researchers have uncovered...

Sea level rise will impact populated areas along the coast up to four times faster as a result of land subsidence, according to a new study from the <a href="https://www.uea.ac.uk/">University of East Anglia</a>. The investigation is the first of of its kind to analyze global sea-level rise while accounting for measurements of sinking <a href="https://www.earth.com/news/more-than-one-third-of-the-corn-belt-impacted-by-farmland-erosion/">land</a>.

Prior to this study, the impact of subsidence combined with sea-level rise was thought of as a local issue. But the researchers have found the problem worldwide. 

The experts report that over the past two decades, coastal communities have experienced average sea level rise at a rate of 7.8 - 9.9 millimeters per year. Meanwhile, the global average rise was 2.6 millimeters per year.

The researchers said that the impacts for coastal communities are far larger than what has been estimated by the Intergovernmental Panel on Climate Change (IPCC).

Study lead author Professor Robert Nicholls is the director of the UK's Tyndall Centre for Climate Change Research and Chair of Climate Adaptation at the University of East Anglia.

"Climate induced sea-level rise is caused by melting glaciers and thermal expansion of water due to rising global temperatures," said Professor Nicholls.

"Rapid rates of subsidence in deltas and especially cities on deltas are also human-caused, mostly due to groundwater pumping, also oil and gas extraction, and sediment resupply prevented by upstream dams, flood defences, sand extraction or mining."

"About 58 percent of the world's coastal population lives on deltas where land is subsiding. Less than 1 per cent of global coastal population lives where land is uplifting.

"We wanted to look at the big picture globally, to better understand the impact of global sea-level rise combined with measurements of sinking land."

"We found that coastal populations live with sea-level rise at three and four times the global average and that the impacts of sea-level rise being experienced today are much larger than the global numbers being reported by the Intergovernmental Panel on Climate Change (IPCC)."

According to Professor Nicholls, addressing human-induced subsidence is important in the short term, as it is an essential coastal adaptation to protect people and economies.

The researchers found that the issue is most urgent in coastal communities located in southeastern Asia. This region has many subsiding deltas and coastal flood plains, growing coastal megacities, and more than 70 percent of the world's coastal population.

The team also determined that land subsidence has been stopped or greatly reduced in Tokyo, Shanghai, and Bangkok as a result of reduced groundwater extraction.

"One of the main reasons that Jakarta, the capital city of Indonesia, is being moved to Borneo is because the city is sinking due to groundwater extraction from shallow wells," said Professor Robert Nicholls.

"We hope that our analysis improves the understanding of how sea-level rise and subsidence are hand-in hand for science and coastal management policy worldwide. Jakarta might be just the beginning."

The study is published in the journal <a href="https://www.nature.com/nclimate/">Nature Climate Change</a>.

Today’s Video of the Day 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.



"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.



"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."

Today's Video of the Day 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.



"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.



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.

Today’s Video of the Day 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;



"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.



"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."



"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."

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



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

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



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;



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;



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. 



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.



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.

Today’s Video of the Day 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.



“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. 



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.



“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;



“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.”



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



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.

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. 



"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."



"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.



"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today’s Video of the Day from <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes why experts are studying zebrafish to gain a better understanding of how the immune system responds to injury. Zebrafish have the ability to repair and regenerate organs.



“Organ regeneration offers an exciting opportunity for studying the immune system and to inquire why some species can regenerate organs like the heart or missing limbs while others like humans cannot,” explained Dr. Tatjana Piotrowski.



Zebrafish sensory organ hair cells are an ideal system to investigate the pathways and cell types involved in regeneration since they are easily destroyed with antibiotics and begin regenerating within five hours. This enabled the researchers to identify the exact timing and genetic programs for each anti-inflammatory macrophage activation state.&nbsp;



“Our hypothesis is that human macrophages do not receive the proper chemical activation 'cocktail' to instruct pro-regenerative processes,” said Dr. Nicolas Denans. “Identifying the molecular recipe of macrophage activation in zebrafish may one day enable us to design regenerative immunotherapies in humans.”&nbsp;&nbsp;&nbsp;



“The new evidence is a valuable resource for comparative studies on the genetic programs involved in macrophage-mediated repair and regeneration. In other words, different types of injuries may induce different kinds of inflammatory responses. We want to decipher whether this 'language' is universal or if there are a variety of dialects."

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes how record-breaking heat expressed itself around the world in 2022.



Scientists have determined that 2022 was the 5th warmest year since 1880. Furthermore, the last nine consecutive years have been the warmest on record.



From devastating floods and wildfires to natural disasters like Hurricane Ian, 2022 showed us yet again how a warming climate affects people across the globe.&nbsp;



"As we look back at 20:22 and years past, we see that each year we better understand the challenges we face and how important it is to meet them," says NASA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth.

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.
