As the sky darkens tonight, the Flower Moon will rise, casting its luminous glow across the world. Despite being a micromoon, it will still command attention.



The Flower Moon is named for the abundance of blooming flowers that typically appear&nbsp;this month. It reminds us to pause and reflect as the <a href="https://www.earth.com/news/how-the-sun-might-be-making-water-on-the-moon/" target="_blank" rel="noreferrer noopener">night</a> sky takes on a calm, serene appearance.



<h2 class="wp-block-heading" id="h-meaning-of-the-flower-moon">Meaning of the Flower Moon</h2>



Long ago, Native American tribes named May’s full moon the Flower Moon as a tribute to nature’s seasonal spectacle.



Spring awakens, flowers bloom, and the moon - like a silver lantern - watches over the Earth. The Comanche tribe saw the blooming fields and named it the Flower Moon, a time of growth and renewal.



The Creek and Choctaw people, however, called it the Mulberry Moon. Mulberries ripened, offering food and dye, and the moon marked the season of abundance. 



The Cree tribe, listening to the chorus of frogs, named it the Frog Moon. Spring returned, and with it, the croaking songs echoed through the <a href="https://www.earth.com/news/total-lunar-eclipse-will-paint-the-moon-blood-red-tomorrow/" target="_blank" rel="noreferrer noopener">night</a>.



For the Anishnaabe tribe, the Blossom Moon symbolized nature’s floral display. Meanwhile, the Apache noticed the trees coming alive with green leaves. They called this moon the “season when the leaves are green,” a simple yet vivid reminder of nature’s cycle.



<h2 class="wp-block-heading" id="h-micromoon-with-a-big-presence">Micromoon with a big presence</h2>



Tonight's Flower Moon is known as a micromoon. Its orbit pulls it farther from Earth, stretching to a distance of 251,939 miles. 



<a href="https://spaceplace.nasa.gov/moon-distance/en/" target="_blank" rel="noreferrer noopener">NASA confirms</a> that this extra distance causes the <a href="https://www.earth.com/news/dry-side-of-the-moon-reveals-new-details-about-its-evolution/" target="_blank" rel="noreferrer noopener">moon</a> to appear smaller than usual. Its average distance sits at 238,855 miles, making the Flower Moon a subtle presence in the sky.



Still, the moonlight gently washes over the night, casting a soft, silvery glow that gives the landscape a dreamlike quality.



As the sun dips below the horizon, the moon will climb slowly in the southeastern sky. By midnight, it will hang high above. For the best view, find a dark, open space away from city lights. 



<h2 class="wp-block-heading" id="h-flower-moon-connects-us-to-nature">Flower Moon connects us to nature</h2>



Throughout history, people have looked to the moon as a guide for planting, harvesting, and marking time. Farmers once relied on the full moon’s light to work late into the night. 



The Flower Moon, with its connection to the season’s peak bloom, became a symbol of abundance and renewal.



Today, the Flower Moon is still a beautiful sight to behold, but it's no longer tied to specific cultural events.



<h2 class="wp-block-heading" id="h-full-moons-in-2025">Full Moons in 2025</h2>



May’s Flower Moon closes the chapter on a series of micromoons in 2025. The first two appeared in January and February - each one pulling away from Earth, and each one smaller than the last. The Flower Moon, the final act, drifts farther than ever.



The Flower Moon may mark the end of the micromoons, but the lunar calendar is far from over. June will bring the Strawberry Moon, named for the ripening berries that herald summer’s arrival. 



July’s Buck Moon will signal the growth of antlers on young deer, a symbol of nature’s <a href="https://www.earth.com/news/saturns-rings-beautiful-iconic-will-disappear-this-weekend-ring-plane-crossing/" target="_blank" rel="noreferrer noopener">cycle</a> of renewal.



August will usher in the Sturgeon Moon - a nod to the fish that once filled North American rivers. September’s Corn Moon will shine as the cornfields sway in the wind. 



October will bring the first of three supermoons, the Harvest Moon, its light brighter and larger than usual. November’s Beaver Moon and December’s Cold Moon will complete the cycle.



<h2 class="wp-block-heading" id="h-eclipses-and-celestial-drama-in-2025">Eclipses and celestial drama in 2025</h2>



This year, the night sky holds more than full moons. September will bring two dramatic eclipses, each one a spectacle in its own right.



On September 7 and 8, a total lunar eclipse will turn the moon a haunting shade of red. A blood moon, some call it. The eclipse will be visible across Europe, Africa, Asia, Australia, and parts of South America.



Later, on September 21, the moon will slide between the sun and Earth, creating a partial solar eclipse. 



Those in Australia, Antarctica, and the Pacific Ocean will witness the sun’s light dim as the moon casts its shadow.

Tonight's Flower Moon completes 2025's micromoon trilogy

As the sky darkens tonight, the Flower Moon will rise, casting its luminous glow across the world. Despite being a micromoon, it will still command attention. The Flower Moon is named for the abundance of blooming flowers that typically appear&nbsp;this month. It reminds us to pause and reflect as the night sky takes on a calm, serene appearance.

Although methane emissions have been increasing rapidly over the past years, contributing significantly to <a href="https://www.earth.com/news/climate-change-disrupts-communication-among-animals/">climate</a> change, this problem is not adequately treated within current national and international governance frameworks. A new study led by the <a href="https://www.iass-potsdam.de/de">Institute for Advanced Sustainability Studies</a> (IASS) in Potsdam, Germany highlights the urgent need for action to curb methane emissions in order to mitigate global warming.&nbsp;



Under the Paris Agreement, the effects of all greenhouse gases are expressed in terms of “CO2&nbsp;equivalents,” a unit of measurement which reflects these gases’ warming effects over a period of 100 years. However, such an approach fails to adequately represent methane’s impact on the climate, while also neglecting its negative effects on human health and ecosystems.



“Governing methane based on assigning it a “CO2&nbsp;equivalence” means that only its climate impact on a 100-year timescale is robustly taken into account – including within carbon pricing schemes, for example,” said study lead author Kathleen Mar, an expert in Atmospheric Chemistry at IASS.



“This neglects methane’s critically important role in near-term climate – over the course of the next 20 years – during which time methane’s warming impact is roughly 80 times greater than that of CO2. Methane’s short atmospheric lifetime means that efforts to reduce emissions can rapidly reduce atmospheric concentrations and, as a consequence, global warming.”



Methane emissions are caused by both natural and anthropogenic factors, including wetlands, fires, fossil fuels, agriculture, and waste management. While scientists have already noted that these emissions have increased dramatically in recent years, the full scope of methane pollution is still underestimated. For instance, methane emissions due to leakages from gas and oil operations are underreported, while in the agricultural sector, reporting remains dominated by basic estimation methods.



However, some developments in controlling these emissions – such as the “Global Methane Pledge” to reduce emissions by at least 30 percent during this decade that was signed by 100 countries at the COP26 Climate Summit in Glasgow – offer a glimmer of hope that the impact of this harmful gas on our planet could be mitigated.



According to Dr. Mar, swift implementation of these pledges is critical. “When it comes to climate change, governments have often failed to deliver on their promises. This doesn’t have to be the case when it comes to methane: significant reductions in methane emissions are within our reach with available technologies and cost-effective measures, including the improved detection of leakages in the oil and gas industry as well as methane capture and utilization technologies for landfills."

Impacts of methane emissions are greatly underestimated

Although methane emissions have been increasing rapidly over the past...

A new study led by <a href="https://www.gsu.edu/">Georgia State University</a> (GSU) has created genetically-edited hamsters in order to shed more light on the mechanisms structuring social behavior. By using CRISPR-Cas9 gene-editing technology to eliminate the actions of a neurochemical signaling pathway which plays a critical role in regulating social behavior in <a href="https://www.earth.com/news/mammals-change-their-schedules-to-adapt-to-city-life/">mammals</a>, the experts reached a startling, unexpected conclusion about the biological underpinnings of social interaction.



Scientists have long known that the hormone vasopressin, together with the receptor that it acts on (called Avpr1a) regulate a wide range of social phenomena, including cooperation, pair bonding, social communication, dominance, and aggression. Now, the researchers discovered that knocking out the Avpr1a receptor in hamsters, and thus eliminating vasopressin’s action on it, fundamentally altered the expression of social behavior in highly unexpected ways.



“We were really surprised at the results,” said study senior author H. Elliott Albers, a professor of Neuroscience at GSU. “We anticipated that if we eliminated vasopressin activity, we would reduce both aggression and social communication. But the opposite happened.”&nbsp;



Surprisingly, hamsters without this receptor showed much higher levels of social communication behavior than those with intact receptors. Moreover, the typical sex differences structuring aggressive behavior were eliminated, with both male and female hamsters displaying high levels of aggression towards their same-sex conspecifics.&nbsp;



“This suggests a startling conclusion,” Professor Albers said. “Even though we know that vasopressin increases social behaviors by acting within a number of brain regions, it is possible that the more global effects of the Avpr1a receptor are inhibitory.”



“We don’t understand this system as well as we thought we did. The counterintuitive findings tell us we need to start thinking about the actions of these receptors across entire circuits of the brain and not just in specific brain regions.”



Since the social organization of hamsters is far more similar to humans than that observed in mice (the most common animal used in laboratory experiments), these results could help clarifying the mechanisms of human social interaction, better understanding how a wide range of neuropsychiatric conditions develop, and developing innovative treatments of such disorders.&nbsp;



“Developing gene-edited hamsters was not easy. But it is important to understand the neurocircuitry involved in human social behavior and our model has translational relevance for human health.&nbsp;Understanding the role of vasopressin in behavior is necessary to help identify potential new and more effective treatment strategies for a diverse group of neuropsychiatric disorders ranging from autism to depression,” Professor Albers concluded.



The study is published in the journal <a href="https://www.pnas.org/doi/10.1073/pnas.2121037119">Proceedings of the Royal Academy of Sciences</a>.

Hamsters reveal new clues about social behavior in mammals

A new study led by Georgia State University (GSU) has...

A new study led by the <a href="https://med.nyu.edu/">NYU Grossman School of Medicine</a> has found that running increases the levels of a chemical involved in brain cell growth – the so-called “brain-derived neurotrophic factor” (BDNF) - that triggers the release of <a href="https://www.earth.com/news/dopamine-plays-a-central-role-in-songbird-mating/">dopamine</a>, a hormone which plays a crucial role in motivation, movement, and learning.&nbsp;



Scientists have long known that regular running raises dopamine activity in the brain, and could protect nerve cells from damage. Moreover, previous research has found correlations between exercise-driven boosts of BDNF and dopamine levels and significant improvements in learning and memory. However, the precise ways in which these factors interact has remained a mystery.



In the new study, researchers provided dozens of male mice with unlimited access to either a freely rotating wheel or a locked, immobile wheel.&nbsp;



After a month, they measured BDNF and dopamine levels in the mice’s brains, and found that running on a wheel for 30 days led to a 40 percent increase in dopamine release in the dorsal striatum – a part of the brain involved in movement – and a nearly 60 percent increase in BDNF levels, compared to their non-running counterparts.&nbsp;



The dopamine levels remained high even after a week of rest. However, when BDNF levels were artificially reduced, running did not result in additional dopamine release.



“Our findings suggest that BDNF plays a key role in the long-lasting changes that occur in the brain as a result of running,” said study lead author Guendalina Bastioli, a postdoctoral fellow in Neurobiology at<a href="https://nyulangone.org/"> NYU Langone Health</a>. “Not only do these results help explain why exercise makes you move, think, and feel better, they also show that these benefits continue even if you do not work out every day.”



Since patients with Parkinson’s disease and other movement disorders are often treated with drugs mimicking the effect of dopamine on motor neurons, the results of this study could open paths for non-pharmaceutical treatment of such disease.&nbsp;



“Our results help us understand why exercise alleviates the symptoms of Parkinson’s disease, as well as those of neuropsychiatric disorders such as depression,” said study senior author Margaret Rice. “Now that we know why physical activity helps, we can explore it as a means of augmenting or even replacing the use of dopamine-enhancing drugs in these patients.”



Further research is needed to investigate whether these findings could be easily translated from rodents to humans, and to fully understand the role of BDNF and dopamine in movement disorders.



The study is published in the journal <a href="http://dx.doi.org/10.1523/JNEUROSCI.2273-21.2022">JNeurosci</a>.&nbsp;&nbsp;

Why running can help you move, think, and feel better

A new study led by the NYU Grossman School of...

A new study led by the <a href="https://www.exeter.ac.uk/">University of Exeter</a> has found that much of the excess heat stored in the subtropical North Atlantic is in the deep part of the <a href="https://www.earth.com/news/95-percent-of-ocean-could-become-inhospitable-this-century/">ocean</a>, below 700 meters. The scientists estimated that, over the next 50 years, the deep ocean’s temperatures will increase by a further 0.2°C.&nbsp;



Until now, oceans have absorbed about 90 percent of the warming caused by human activities. By using temperature records and “chemical tracers” – compounds whose composition can be used to discover past changes in the oceans – the researchers have found that, in the subtropical North Atlantic, 62 percent of the warming from 1850 to 2018 is held in the deep ocean. This warming will most likely have a negative impact on our planet, leading to sea-level rise, changing ecosystems, ocean currents and chemistry, and deoxygenation.



“As our planet warms, it’s vital to understand how the excess heat taken up by the ocean is redistributed in the ocean interior all the way from the surface to the bottom, and it is important to take into account the deep ocean to assess the growth of Earth’s ‘energy imbalance,’” said Dr. Marie-Jose Messias, a senior lecturer in Oceanography at the University of Exeter.&nbsp;



“As well as finding that the deep ocean is holding much of this excess heat, our research shows how ocean currents redistribute heat to different regions. We found that this redistribution was a key driver of warming in the North Atlantic.”



According to Dr. Messias and her colleagues, the main cause of North Atlantic deep ocean warming is the system of currents known as the Atlantic Meridional Overturning Circulation (AMOC). This system works like a conveyor belt, carrying warm water from the tropics north, where colder and denser water sinks into the deep ocean, slowly spreading southward. Thus, excess heat from the Southern Hemisphere oceans is constantly transferred to the North Atlantic by AMOC.



Further research is needed to clarify the mechanisms of heat transferred from the Southern to the Northern Hemisphere oceans, and the role that AMOC plays in these processes.

Deep ocean temperatures are steadily rising

A new study led by the University of Exeter has...

A recent study led by the <a href="https://www.hull.ac.uk/">University of Hull</a> highlights another grim consequence of <a href="https://www.earth.com/news/climate-change-will-supercharge-forest-disturbances/">climate</a> change. The researchers have found that shifting climate conditions are disrupting chemical communication within marine, freshwater and terrestrial ecosystems.



The researchers have demonstrated that climate change affects interactions among organisms across different types of ecosystems in similar ways. Disruptions in chemical communication can wreak havoc on a species and an ecosystem. They affect mating patterns, predator/prey systems, and the ability of animals to find food.



"Chemical communication is the ubiquitous language of life on earth - but this is being jeopardized by global change. There's no talking with words for life underwater, so aquatic organisms' talk' in chemical signals. But this fine-tuned 'language' is in peril," said study co-author Dr. Patrick Fink.



In the paper, the international team of researchers demonstrates that climate change has a similar impact on communication in terrestrial and aquatic environments, even though both environments have different stressors.&nbsp;&nbsp;



"Although a growing number of studies suggest that climate change-associated stressors cause adverse effects on the communication between organisms, knowledge of the underlying mechanisms remains scarce," said study lead author Dr. Christina C. Roggatz.



"We urgently need a systematic approach to be able to compare results and fully understand the potentially disruptive impact that climate change is having upon each step of this fundamental communication process. Understanding this means we are better equipped to predict and protect the future of our planet."



According to study co-author Dr. Jörg Hardege, as climate change continues, we need more research to predict the consequences at the species interaction level. He noted that we need to research land, sea, and freshwater environments to fully understand how species will function with the coming changes. Without this research, we can only speculate.&nbsp;



Dr. Roggatz concludes that this paper is a "wake-up call" because humans are a part of the ecosystem and rely on it for essential functions. This communication breakdown will have severe consequences for all life on earth, including humans.&nbsp;



"The predominantly negative effects that climate change has upon the language of life within terrestrial and aquatic ecosystems could have a range of far-reaching implications for the future of our planet and human wellbeing, for example by impacting food security and fundamental ecosystem services that make our planet habitable."



The study is published in the journal <a href="https://onlinelibrary.wiley.com/journal/13652486">Global Change Biology</a>.

Herbal supplements may not always be safe, according to a new study published by <a href="https://www.elsevier.com/">Elsevier</a>. The research highlights how serious side effects can result from the imprudent use of herbal supplements.



The report describes a case in which a patient was diagnosed with a dangerous cardiac arrhythmia after taking hemp oil containing <a href="https://www.earth.com/news/cbd-improves-eases-arthritis-symptoms-in-dogs/">CBD</a> and CBG along with berberine supplements.



“More and more people are taking herbal supplements for their potential benefits. Yet their ‘natural’ character can be misleading, since these preparations can have serious adverse side effects on their own or if combined with other supplements or medications,” said Dr. Elise Bakelants, an expert in the Department of Cardiology at the University Hospital of Geneva. “Their use should not be taken lightly, and dosing recommendations should always be respected.”



The study examined the case of a 56-year-old woman who experienced dizziness and fainting without warning. After physical exams came back as normal, doctors determined that the condition was caused by the herbal supplements she was taking to cope with stress.&nbsp;



Four months earlier, the patient had started taking six times the recommended dose of hemp oil, and had recently added berberine to the mix. She was then diagnosed with a life-threatening cardiac arrhythmia.



During her hospital stay, all supplements were stopped resulting in positive changes, which strongly validated a link between the supplements and the arrhythmia.



The popularity of herbal supplements has grown in recent years, especially those containing CBD (cannabidiol). This particular supplement is very accessible and available without any prescription.&nbsp;



CBD has been promoted for its anti-inflammatory, antipsychotic, and immunomodulatory properties. The products do not contain THC (tetrahydrocannabinol) - therefore, it is not subjected to scrutiny by drug regulatory agencies.&nbsp;



Berberine, found in many medicinal plants, is frequently used in traditional Chinese and ayurvedic medicine for various types of treatment.&nbsp;



The preparation of herbal supplements is largely unregulated. Exact composition can vary greatly from one distributor to another, and properties of these substances are not well known. There are limited data on their effectiveness and toxicity, making it&nbsp; difficult to predict potential side effects.



Dr. Bakelants cautioned patients and physicians to follow dosing recommendations and consider possible interactions with other medications, particularly in patients with underlying cardiac disease or those already taking QT-prolonging medication.



The study is published in the journal <a href="https://www.heartrhythmcasereports.com/">HeartRhythm Case Reports</a>.

The ways in which we produce <a href="https://www.earth.com/news/food-production-linked-to-one-third-of-global-emissions/">food</a> and manage our lands are responsible for almost a third of global greenhouse gas emissions along the entire supply chain. A new study led by the <a href="https://www.pik-potsdam.de/en/home">Potsdam Institute for Climate Impact Research</a> (PIK) has found that just shrinking the size of our current food system will not substantially cut emissions. Instead, the experts argue that fundamental transformations in the very nature of the global food system are necessary in order to fix these problems.



“That means on the one hand that people consume what they need in terms of nutritional requirements, curb food waste, and eat a more balanced diet, with much more vegetables and less animal products,” explained study lead author Benjamin Bodirsky, a senior scientist at PIK.



“On the other hand, a qualitative transformation means more efficiency, hence producing food in a less-polluting way: smarter dosing of fertilizers or planting higher-yield crops. Also, carbon pricing could help steer farmers towards lower-emission agricultural practices, because emitting less means paying less. Put together, this could drastically reduce greenhouse gas emissions.”



Dr. Bodirsky and his colleagues performed an in-depth review of degrowth proposals and created a set of scenarios which they fed into a food and land systems computer simulation to explore their effect on the food system. These analyses revealed that the current food system is unsustainable for any society, regardless of economic growth rates.



According to the simulations, simply curbing growth in rich countries would not lead to sizable sustainability benefits in the food system. Moreover, financial transfers from richer to poorer countries within the current development paradigms could even increase emissions, since carbon-intensive diet changes are most pronounced when countries move from low to medium incomes.



However, when the researchers included consumption changes and efficiency gains incentivized by the price of carbon, the results pointed towards improved nutritional outcomes for all consumers, as well as lower greenhouse emissions.&nbsp;



“For the food sector, we can say that a certain degree of degrowth would be the result of the sustainable transformation, not the starting point,” said study co-author Hermann Lotze-Campen, an agricultural economist at PIK. “So basically this is not really about less but about different growth.”



Since a sustainable food system transformation that takes into account all costs to the environment would lead to a slight increase in food prices, any such changes must be accompanied by a comprehensive policy mix of smart taxing schemes, social compensation for carbon dioxide pricing, and international transfers. Finally, making agriculture more climate friendly – by controlling nitrogen flows in croplands for, instance – would entail further investments. According to the experts though, all these costs will likely be offset by the urgently needed restoration of crucial ecosystem services.

The <a href="https://www.sfbbo.org/">San Francisco Bay Bird Observatory</a> (SFBBO) runs a bird banding station nestled into a small riparian <a href="https://www.earth.com/news/deforestation-threatens-two-new-fish-species-with-extinction/">forest</a> stand among hustle and bustle of Silicon Valley. The scientists capture birds in "mist nets." The nets are too fine for animals to see until they are entangled in them. After the birds are carefully extracted, the experts take notes on their health and collect other data before releasing them.



The observatory has over 30 years of data accumulated, consisting of information on more than 100,000 individual birds. Many of the birds are captured multiple times, giving insight to their health over a span of time. With this unusually large amount of data, SFBBO ornithologist Dr. Katie LaBarbera plans to look into the welfare of the avian research subjects.



The researchers will investigate how injured or sick birds fare after leaving the banding station - something Dr. LaBarbera hopes could inform rehabilitation and other banding stations. With this information, bird care could improve.&nbsp;



The project is just one of <a href="https://www.wildanimalinitiative.org/blog/grants-2022">seven studies </a>selected to be funded by the Wild Animal Initiative, a non-profit focused on wild animal welfare. For their part, Dr. LaBarbera is driven by a love and fascination for birds.&nbsp;&nbsp;



“Holding a wild bird is a very specific joy…They’re fragile, but they’re also really fierce," said Dr. LaBarbera.&nbsp;



“You get a sense for the sort of alien body structure they have. It becomes obvious that they evolved from dinosaurs."



"Another interesting detail is that their skin is basically transparent. Unlike mammals, which store fat in a continuous layer under the skin, birds store fat under their skin in just a few places, so if you gently blow the feathers out of the way, you can see things like their muscles or the food they ate.”



Dr. LaBarbera’s experience working with rehab facilities shows that these organizations do the best they can for birds, but can only make decisions based on the best information they have. For instance, some organizations will automatically euthanize one-legged birds, this research could help determine whether such policies are justified.&nbsp;



“We’ve seen one-legged songbirds do well and seem healthy in the wild, so with the results of this study, we might be able to provide better, data-backed guidelines for rehabilitation or release."

Learning more about injured birds could improve their welfare

The San Francisco Bay Bird Observatory (SFBBO) runs a bird...

Researchers at <a href="https://www.psu.edu/">Penn State</a> recently published a paper which suggests that <a href="https://www.earth.com/news/animals-combine-different-strategies-to-survive-the-cold/">animals</a> move their eyes and bodies separately due to an evolutionary function designed to save energy. The study’s principal investigator, Jean-Michel Mongeau, is an assistant professor of Mechanical Engineering.



“When a fly moves, it coordinates its head, wings and body to fly through the air, evade predators or look for food,” said Professor Mongeau. “We discovered that when controlling gaze, fruit flies minimize energy expenditure and increase flight performance.”&nbsp;



The researchers had the flies enter a virtual reality experiment that simulated free flying. They recorded the flies’ movements using high-speed cameras to conduct their analysis.&nbsp;



“We found that the fly’s head and body movements were complementary, in that the body moved most during slower visual motion, while the head moved most during faster motion,” said Professor Mongeau.&nbsp;



The experts believe that having the head and body work cooperatively is energy efficient for animals. “Since the head is smaller, it has less resistance to motion, or inertia, which means it can respond to quick movements, while the much larger body responds best to slower movement," explained Professor Mongeau.&nbsp;



Using the fruit fly data, the researchers developed a model that can be applied to other insects, rats, and birds. The team also considered primates,



“The way the flies move their head and body is very similar to the way primates move their heads and eyes, which is remarkable since they diverged hundreds of millions of years ago," said Professor Mongeau.



The development of independent eye movement saves more energy since eye movement requires less energy than head movement.&nbsp;



Professor Mongeau believes that the evolution of independent eye movement was integral for our ancestors as they transitioned from ocean to land. This idea is based on the fossil record, which indicates that vertebrates began gaining independent movement of head and eyes when they started moving to land habitats.&nbsp;



“As vertebrate animals transitioned from water to land more than 350 million years ago, the development of mechanisms to control head and eye movements could have had substantial evolutionary benefits,” said Professor Mongeau. “We discovered that there is a sweet spot in eye-head-body ratios, suggesting that inertia may have been an important constraint in the evolution of vision.”



The experts said that their results will influence robotic development. Study first author Benjamin Cellini explained that in robotics, sensors are typically fixed in location. “But in the animal kingdom, sensing and movement are coupled, as many physical sensors, like eyes, move. Inspired by biology, we can design more energy-efficient robots by making vision-based sensors mobile.”&nbsp;



This study is published in the journal <a href="https://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.&nbsp;

Animals move their eyes and bodies separately to save energy

Researchers at Penn State recently published a paper which suggests...

Experts at <a href="https://wsu.edu/">Washington State University</a> have developed a smart pacifier that may ultimately eliminate the need for invasive blood draws among <a href="https://www.earth.com/news/babies-are-exposed-to-microplastics-before-theyre-even-born/">babies</a> in Newborn Intensive Care Units (NICUs). The new pacifier can continuously monitor sodium and potassium ion levels. These electrolytes are an indicator of dehydration, which is especially dangerous for infants born with health issues.&nbsp;



When the researchers tested the smart pacifier on a select group of newborns, they found the monitoring results were comparable to data gained from the normal blood draws.&nbsp;



“We know that premature babies have a better chance of survival if they get a high quality of care in the first month of birth,” said study co-author Professor Jong-Hoon Kim. “Normally, in a hospital environment, they draw blood from the baby twice a day, so they just get two data points. This device is a non-invasive way to provide real-time monitoring of the electrolyte concentration of babies.”



The traditional blood-draw method is not only potentially painful, but also leaves big gaps in information since the draws are usually done once in the morning and once in the evening, noted Kim.



The researchers modified a common pacifier by creating a system that samples a baby’s saliva through microfluidic channels. The saliva is naturally attracted to these channels, so no pumping system is needed. Inside of the channels, small sensors measure the sodium and potassium ion concentrations in the saliva. This data is wirelessly transmitted to the caregiver via Bluetooth.



Next, the researchers plan to make the components more affordable and recyclable. Kim said development of this device is part of a broader effort to help make NICU treatment less disruptive for their tiny patients.



“You often see NICU pictures where babies are hooked up to a bunch of wires to check their health conditions such as their heart rate, the respiratory rate, body temperature, and blood pressure. We want to get rid of those wires.”

Smart pacifier can monitor the health of babies

Experts at Washington State University have developed a smart pacifier...

Scientists have long tried to understand “the paradox of stress behavior:” why humans – as well as other <a href="https://www.earth.com/news/baboons-sacrifice-sleep-to-meet-lifes-daily-demands/">primates</a> – show signs of stress (fidgeting, scratching, nail-biting, touching their face or hair), which could show others that they are in a weakened state. 



Now, a research team led by <a href="https://www.ntu.ac.uk/">Nottingham Trent University</a> (NTU) and the <a href="https://www.port.ac.uk/">University of Portsmouth</a> has found that showing signs of stress could make us more likeable and prompt other people to act more positively towards us. The study revealed that, besides being able to quickly and accurately identify when someone is stressed, people usually reacted more positively to those exhibiting more signs of stress.



The researchers filmed a group of participants while taking part in a mock presentation and interview. These videos were then presented to raters, who were asked to assess how stressed they thought the participants were. People who reported feeling more stressed during the task, as well as those who exhibited signs of stress such as nail-biting or scratching, were also perceived to be more stressed by the raters. These findings suggest that humans can accurately detect when others are stressed from their behaviors.



Interestingly, the participants who were identified to be more stressed were also perceived as more likeable by others, which may offer a clue regarding why humans have evolved to display stress signals. “We wanted to find out what advantages there might be in signaling stress to others, to help explain why stress behaviors have evolved in humans,” said study lead author Jamie Whitehouse, a research fellow in Psychology at NTU.



“If producing these behaviors leads to positive social interactions from others who want to help, rather than negative social interactions from those who want to compete with you, then these behaviors are likely to be selected in the evolutionary process. We are a highly cooperative species compared to many other animals, and this could be why behaviors which communicate weakness were able to evolve.”



“If the individuals are inducing an empathetic-like response in the raters, they may appear more likeable because of this, or it could be that an honest signal of weakness may represent an example of benign intent and/or a willingness to engage in a cooperative rather than competitive interaction, something which could be a ‘likable’ or preferred trait in a social partner,” added study senior author Bridget Waller, a professor of Evolution and Social Behavior at NTU.



“This fits with current understanding of expressivity, which tends to suggest that people who are more “emotionally expressive” are more well-liked by others and have more positive social interactions.”



The researchers are now investigating whether young children also show a similar sensitivity to stress states. In addition, they aim to clarify how exposure to adults’ stress may impact children.

A research team led by the non-governmental organization <a href="https://www.paralatierra.org/">Para la Tierra</a> has recently discovered a striking new snake <a href="https://www.earth.com/news/new-report-confirms-that-bird-species-are-steadily-declining/">species</a> belonging to the genus Phalotris, which comprises 15 semi-subterranean species distributed across central South America.&nbsp;The study was a collaboration with Guyra Paraguay and the Institute of Biological Investigations of Paraguay.



The species was named Phalotris shawnella in the honor of two children, Shawn Ariel Smith Fernández and Ella Bethany Atkinson, who were born in the same year&nbsp;as Para la Tierra. The children inspired the founders of this organization to start their initiative of conserving Paraguayan wildlife to help children inherit a better world.&nbsp;



A specimen of P. Shawnella was spotted by chance in 2014 at Rancho Laguna Blanca by Jean-Paul Brouard, a researcher at Para la Tierra, while he was digging a hole. The snake is non-venomous and can be distinguished from other related species in the Phalotris genus by its red head, yellow collar, a black lateral band, and orange ventral scales with irregular black spots.



Until now, only three specimens of P.shawnella were discovered in the Cerrado forests of the department of San Pedro in east Paraguay. The extreme rarity of this species led scientists to list it as “endangered,” according to the conservation categories set by the&nbsp;<a href="https://www.iucn.org/">International Union for Conservation of Nature&nbsp;</a>(IUCN). The famous tourist destination Laguna Blanca – the only place where specimens of P.Shawnella were spotted - is now declared an “Important Area for the Conservation of Amphibians and Reptiles.”



“This demonstrates once again the need to protect the natural environment in this region of Paraguay,” wrote the study authors. “Laguna Blanca was designated as a Nature Reserve for a period of five years, but currently has no protection at all. The preservation of this site should be considered a national priority for conservation.”



“Additional field surveys are urgently required to improve our understanding of the ecological requirements of [this species] so that effective conservation measures can be implemented,” they concluded.



A full description of the new snake species can be found in the journal <a href="https://doi.org/10.3897/zse.98.61064">Zoosystematics and Evolution</a>.

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

</div></figure>



Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</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;

'The weather of Santiago resembles the Mediterranean climate with dry and warm summers with temperatures reaching up to 35°C (from October to March) and cool and humid winters that can drop to 0°C (from April to September)."



"The city lies in the centre of the country’s central valley around 80 km from the Pacific Ocean to the west and borders Argentina to the east. A tiny part of Argentina is visible in the top-right corner of the image where the mountain crest of the Andes Mountains acts as a divider between the two countries," says ESA.

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.

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. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.
