The COVID-19 lockdown reshaped lives in many ways, including how people approached pet ownership. During the pandemic, a surge in puppy purchases swept across the U.K. as individuals and families sought companionship while they were confined to their homes.



While many welcomed new furry companions with open arms, concerns arose about the long-term consequences of these impulsive adoptions.



Would owners remain committed once life returned to normal? Would these dogs develop behavioral problems due to rushed decisions and inadequate training? Researchers at The Royal Veterinary College (<a href="https://www.rvc.ac.uk" target="_blank" rel="noreferrer noopener">RVC</a>), U.K., led by Dr. Bree Merritt, set out to answer these questions.



The study, published in the journal PLOS One, reveals the complex reality of pandemic <a href="https://www.earth.com/news/reimagining-pet-diets-for-a-more-sustainable-future/" target="_blank" rel="noreferrer noopener">puppy ownership</a>.



<h2 class="wp-block-heading" id="h-puppy-purchases-during-the-pandemic">Puppy purchases during the pandemic</h2>



As lockdown measures took hold in early 2020, people found themselves spending more time at home. Many saw this as the perfect opportunity to welcome a <a href="https://www.earth.com/news/national-dog-day-honoring-mans-best-friend/" target="_blank" rel="noreferrer noopener">puppy</a> into their lives.



The demand for dogs soared, leading to inflated prices, overwhelmed breeders, and, in some cases, unethical breeding practices.



Animal welfare experts expressed concerns about the potential fallout. They worried that some buyers acted impulsively, without considering whether they could provide for a dog long-term. Would these pandemic puppies face neglect, abandonment, or behavioral struggles in homes that were unprepared for their needs? 



These questions fueled the need for deeper research into the experiences of owners and their dogs.



<h2 class="wp-block-heading" id="h-tracking-pandemic-puppy-owners">Tracking pandemic puppy owners</h2>



To better understand the reality of pandemic <a href="https://www.earth.com/news/dog-owners-ages-and-beliefs-influence-their-pet-food-choices/" target="_blank" rel="noreferrer noopener">puppy ownership</a>, the researchers surveyed nearly 800 U.K. dog owners who had purchased a puppy between March and December 2020. The study aimed to uncover their motivations, training approaches, and overall experiences.



Participants provided details about their daily interactions with their pets, their emotional connection, and any difficulties they faced. A follow-up survey was conducted when the puppies reached 21 months of age. 



This allowed researchers to assess how ownership experiences evolved over time and whether the initial excitement had given way to unexpected challenges.



<h2 class="wp-block-heading" id="h-owners-stayed-committed-but-at-a-cost">Owners stayed committed, but at a cost</h2>



Despite widespread concerns that many pandemic puppies would end up abandoned or rehomed, the study found that 98% of surveyed owners still had their dogs at 21 months old. 



This high retention rate suggests that, for most, the commitment to their pets remained strong even as their daily routines returned to normal.



However, the study also revealed that ownership came with significant challenges. Of those surveyed, 40% admitted that the pandemic influenced their decision to get a <a href="https://www.earth.com/news/how-dogs-say-goodbye-before-they-die-these-signs-will-tell-you-if-your-friend-is-leaving-soon/" target="_blank" rel="noreferrer noopener">dog</a>.



These owners were more likely to report difficulties related to costs, lifestyle changes, and unexpected responsibilities. Many struggled with cleaning up after their pets, sacrificing personal activities, and managing expenses.



<h2 class="wp-block-heading" id="h-behavioral-issues-and-owner-burden">Behavioral issues and owner burden</h2>



One of the biggest concerns for pandemic puppy owners was behavioral issues. 



Dogs that grew up in lockdown often had limited exposure to the outside world, leading to problems such as separation anxiety, control struggles, and aggression. Owners who reported behavioral difficulties felt a greater burden of dog ownership.



While various problem behaviors caused stress, aggression had the most significant impact. Owners of aggressive dogs experienced a weaker emotional connection with their pets compared to those dealing with other challenges. 



This highlights the importance of early intervention and training to prevent behavioral issues from escalating.



<h2 class="wp-block-heading" id="h-capturing-the-whole-picture">Capturing the whole picture</h2>



The study acknowledged a potential limitation in its findings. Owners who had already rehomed their dogs might have been less likely to participate in the follow-up survey. 



This means the 98% retention rate could represent a best-case scenario. Some dogs may have been relinquished after the survey period ended, making the overall picture more complex than the data suggests.



Additionally, the financial and emotional burdens of dog ownership might have driven some participants to keep their struggles private. Many may have hesitated to admit difficulties, especially if they felt judged for their decision to acquire a dog during the pandemic.



<h2 class="wp-block-heading" id="h-need-for-better-behavioral-support">Need for better behavioral support</h2>



For those who faced challenges with their pandemic puppies, access to evidence-based behavioral support could make a crucial difference. Professional training and behavior modification techniques could help struggling owners manage their dogs more effectively, improving their overall quality of life.



"Relationships with our dogs can be immensely rewarding, but it’s not all fun and games. Looking after them can be hard work, expensive or even change day-to-day activities," noted Dr. Merritt.



"Problem behaviors are likely to be a much wider concern beyond just those dogs who were brought home during the pandemic. These results show how important it is to find evidence-based help for problem behavior to improve the emotional health of <a href="https://www.earth.com/news/friends-family-members-and-guardians-dogs-are-more-than-just-pets/" target="_blank" rel="noreferrer noopener">dogs</a>, their owners and sustain their relationship.”



<h2 class="wp-block-heading" id="h-impulsive-pandemic-puppy-purchases">Impulsive pandemic puppy purchases</h2>



The findings of this study serve as an important reminder that dog ownership requires long-term planning, not just short-term enthusiasm. 



Many pandemic puppy buyers made decisions based on the temporary circumstances of lockdown life. Once restrictions eased and daily routines resumed, they found themselves struggling with responsibilities they had not fully anticipated.



"Impulsive acquisition of dogs based on short-term circumstances is an enduring challenge for the canine welfare sector," said Dr. Rowena Packer, senior author of the study. 



"Here, we demonstrate that puppy purchases that were a direct result of the COVID-19 pandemic, such as having increased time for a dog during this atypical period, resulted in owners who felt a greater burden of dog ownership by the time their puppy was a young adult, compared to owners whose purchases were planned based on longer-term circumstances."



"U.K. campaigns have long encouraged owners to consider their ability to care for a dog for the duration of its lifetime at acquisition. However, if the efficacy of these messages remains limited, greater interventions may be needed to emphasize the responsibilities of dog ownership, ideally prior to purchase.”



<h2 class="wp-block-heading" id="h-a-lifelong-commitment">A lifelong commitment</h2>



While most pandemic puppy owners chose to keep their dogs, the challenges they faced highlight the importance of informed decision-making. 



Owning a dog is not just about companionship; it requires time, effort, and financial resources. Without proper preparation, owners can find themselves overwhelmed, and their pets may suffer as a result.



The study reinforces the need for education and support for prospective dog owners. Those considering bringing a pet into their home must evaluate their long-term ability to care for an animal - not just their immediate desire for companionship.



With the right guidance, future pet buyers can ensure a fulfilling and responsible relationship with their dogs, built on commitment rather than impulse.



The study is published in the journal <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0316166" target="_blank" rel="noreferrer noopener">PLOS One</a>.

Pandemic puppy owners report challenges but remain committed

The COVID-19 lockdown reshaped lives in many ways, including how people approached pet ownership. During the pandemic, a surge in puppy purchases swept across the U.K. as individuals and families sought companionship while they were confined to their homes. While many welcomed new furry companions with open arms, concerns arose about the long-term consequences of these impulsive adoptions. Would owners remain committed once life returned to normal?

A new study from the <a href="https://twin-cities.umn.edu/">University of Minnesota</a> has examined the previously under-reported role of gut fungi in the development of obesity. 

Previous studies have focused solely on how gut bacteria opens the doors to <a href="https://www.earth.com/news/working-night-shift-obesity/">obesity</a>, but very little attention has been paid to gut fungi, which researchers say may play just as crucial a role.

“We really need to be looking at all the microbes and how they are interacting with each other to get a full picture of what the microbiome structure and function is in a given individual,” said Dr. Cheryl Gale, associate professor in in the Department of Pediatrics at the University of Minnesota, and the lead investigator. 

Gut fungi are just as instrumental to gut and metabolic health as bacteria and could also be directly linked to obesity. 

"Although they represent a small component of the microbiota, fungal communities are significant in that they potentially serve as a reservoir for pathogens as well as for keystone species with critical roles in maintaining the function of the gut microbiome,” said Gale. 

Researchers conducted the study using two groups of mice. One group was fed a high-fat diet, and the other kept to a normal diet. 

The mice that were fed a high-fat diet had drastically higher amounts of 19 bacterial and 6 fungal taxa, different than what was in the microbiome of the mice with a normal diet. The high-fat diet also lowered metabolic function. 

Dr. Gale noted that the gut fungi were greatly affected by just a change in diet.

“These kingdoms are not in isolation. If one changes, it is going to impact the community structure and maybe the functional structure of other kingdoms as well. I think that is where the microbiome field is moving,” said Gale. 

This study shows the need for further research into fungi as a part of the microbiome to see its effect on obesity. However, the technology to sequence gut fungi has not yet fully developed, but the researchers hope further studies will push those technologies along.

When we think of underdeveloped or developing countries moving to the next step, it usually comes along with the processes of industrialization and agricultural growth – particularly in the Western world.  However, a new study published in <a href="https://www.ecologyandsociety.org/">Ecology and Society</a> attempts to flip this ideology on its head. 

Ashwin Ravikumar, an environmental social scientists at <a href="https://www.fieldmuseum.org/">The Field Museum</a>, and his colleagues believed that governments have been too quick to dismiss indigenous peoples’ traditional ways of life, and the well being that they create. In many cases, these communities are living a high quality of life through managing their natural resources in a sustainable fashion as a result of traditional hunting, fishing, and small-scale agriculture.

This study details an assets-based approach to conservation. “Rather than fixating on what they lack, we focus on the assets they already have, especially their skills in managing local resources. We create spaces for local communities to think about what choices make the most sense for them,” says Ravikumar.

The researchers worked with rural communities in the Peruvian Amazon, determining that the local populations are able to meet their basic needs through a diverse collection of subsistence activities. These include hunting, fishing, and farming – which over centuries have developed sophisticated natural resource management systems that help protect the <a href="https://www.earth.com/news/illegal-activity-brazilian-amazon/">rainforest ecosystem</a>.

For these indigenous people, “well-being” isn’t defined by owning cars or TVs. “When they talk about well-being, they do talk about money,” says Ravikumar. “But they always include basic needs and natural resources, like having a healthy forest, since forests can be of cultural and spiritual importance.” The indigenous people in the study do rely on money for things such as transportation, but their environment covers most basic needs like food, water, and shelter. 

Through working closely with the people in these communities, the project hopes to lead to the implementation of a conservation plan that complements their existing practices. “We build strong relationships with these communities through a combination of direct work with them on the ground and cataloging how they use traditional knowledge to manage natural resources in an ecosystem,” explains Ravikumar.

Aiding and understanding how these communities sustain themselves will help researchers such as Ravikumar work more efficiently to help them organize politically to gain support from both government and non-government allies, which will help them in the future. In the past, the indigenous people have been exploited by commercial industries as well as their own government. Through this new approach, hopefully their future will be brighter than their past.

Tai chi could be the perfect form of light to moderate exercise for patients who have recently suffered a heart attack. 

A new study, published in the Journal of the American Heart Association, found that Tai chi could be the right alternative for patients who decline or can’t handle traditional cardiac rehabilitation. 

Tai chi, however, consists of slow and gentle movements with a central focus on breathing that can also lower stress. 

Research has found that 69 percent of patients who recently suffered a <a href="https://www.earth.com/news/cold-weather-heart-attack/">heart attack</a> refused cardiac rehabilitation for a number of reasons including cost, distance to a rehab facility, and fear that the exercise will be strenuous and painful. 

Researchers from <a href="https://www.brown.edu/">Brown University</a> considered these factors and developed a modified Tai chi program for interested patients to see if the effects would be beneficial.

“We thought that Tai Chi might be a good option for these people because you can start very slowly and simply and, as their confidence increases, the pace and movements can be modified to increase intensity,” said Elena Salmoirago-Blotcher, assistant professor at the <a href="http://med.brown.edu/">Warren Alpert School of Medicine</a> and lead author of the study. 

The study’s participants included 8 women and 21 men who were heart disease patients at <a href="https://www.miriamhospital.org/">The Miriam Hospital</a> in Rhode Island. 

All of the participants were physically inactive and had declined rehabilitation, even though most had previously had a heart attack. 

The results of the study were very promising, and all of the patients liked doing Tai chi regularly and would even recommend it to a friend. 

The program was not strenuous, and only minor muscular pain was reported by the patients at the beginning.

“If proven effective in larger studies, it might be possible to offer it as an exercise option within a rehab center as a bridge to more strenuous exercise, or in a community setting with the educational components of rehab delivered outside of a medical setting,” said Salmoirago-Blotcher.

Researchers from the <a href="https://www.bumc.bu.edu/busm/">Boston University School of Medicine</a> set out to compare today's beauty standards to what constituted beauty decades back. In order to do this, they analyzed the physical traits and other characteristics of celebrities that made People magazine's World's Most Beautiful list in 1990 and in 2017.

Dr. Neelam A. Vashi and co-authors gathered information on the celebrities which included age, sex, race, skin type, hair color, eye color and any visible dermatologic conditions. The team published their findings in <a href="https://jamanetwork.com/journals/jamadermatology">JAMA Dermatology</a>. The article highlighted significant changes, particularly concerning age, <a href="https://www.earth.com/news/economic-hardship-racial-discrimination/">race</a>, and gender.

The researchers reported that the average age of celebrities on the list increased from 33.2 in 1990 to 38.9 in 2017. In addition, the proportion of females increased from 52 percent in 1990 to 88.1 percent in 2017.


There were also notable differences in the races that were represented on the list. The proportion of celebrities of nonwhite races increased from 24 percent in 1990 to 40 percent in 2017. While celebrities of mixed race were represented by only one person in 1990, there were 14 celebrities of mixed race on the World’s Most Beautiful list in 2017.

In 1990, 88 percent of the celebrities deemed beautiful had lighter skin types and 12 percent had darker skin types. By 2017, lighter skin types dropped to 70.4 percent and darker skin types accounted for 29.6 percent of the list.

"As evidenced by our data and contrary to our hypothesis, at present, a wider variety of skin colors and inclusion of older age groups are represented among those deemed to be the most beautiful,” said the authors of the study. 

“The mass media platform has for years introduced certain criteria for what constitutes beauty. Through an examination of the World's Most Beautiful issue of People, we found that these beauty standards are evolving as people learn how to integrate the effects of media with exposure to new cultures and different norms.”

New study shows standards of beauty becoming more inclusive

Researchers from the Boston University School of Medicine set out...

As more people become aware of the toxic chemicals that are packed into mosquito repellent, there is a high demand for natural alternatives. A new study has identified essential oil from citrus fruit as a potential substitute. The research has revealed that citrus fruit oils may be an effective, eco-friendly way of controlling mosquitoes.

Researchers from <a href="http://www.alexu.edu.eg/index.php/en/">Alexandria University</a> in Egypt extracted large amounts of essential oils from the peel of a citrus fruit similar to an orange, which is widely accessible throughout many regions of the world. 

In order to extract the oil, the team air-dried the peels of three different citrus species which were then cut into smaller pieces and hydro distilled. The researchers conducted tests to evaluate the usefulness of the essential oils in mosquitocidal activity.

The experts found that the oils were highly effective in killing <a href="https://www.earth.com/news/insecticide-attracts-mosquitoes/">mosquitoes</a>. Dr. Mohamed E. I. Badawy is a professor at Alexandria University in the Department of Pesticide Chemistry and Technology and lead author of the research.


"This study, which we believe to be the first of its kind, shows that the essential oils from the peels of citrus plants were very effective against larvae and adults,” said Dr. Badawy. “This means there could be a natural and hugely accessible product available which could be used as a method of mosquito control."

There is an urgent need for accessible mosquito control, particularly in regions of the world that have poor water management and rapid urbanization. These conditions accelerate the transmission of many diseases to humans and animals by mosquitoes. 

The authors point out that further experimentation is needed to confirm the findings of this study and the effectiveness of essential oils in mosquito management. The research is published today in <a href="http://www.tandfonline.com/toc/gnpl20/current">Natural Product Research</a>.

<a href="https://www.earth.com/news/plant-based-diets-heart-disease/">Heart disease</a> is triggered by many causes including diabetes, smoking, and high blood pressure. Even some mental disorders, such as stress and depression, have been linked to dangerous heart conditions. And now, research is emerging that demonstrates how traumatic experiences can also damage heart health. 

According to the <a href="http://www.heart.org/">American Heart Association</a>, a woman dies every minute in the United States from heart disease. There has been little research on the impact of traumatic experiences on vascular health, and even fewer studies have focused on the cardiovascular effects of trauma during menopause, a time when the risk of heart disease is rising.


Researchers at the <a href="http://www.medschool.pitt.edu/">University of Pittsburgh, School of Medicine</a> set out to determine whether a greater number of traumatic experiences is directly linked to cardiovascular health risks. For the study, 272 nonsmoking, menopausal women were evaluated. Traumatic experiences were defined by the team as events such as sexual harassment, death of a child, being in a car accident, experiencing a natural disaster, or being beaten or mugged. 

The researchers focused specifically on the function of the endothelium, the inner lining of the heart and blood vessels. The study revealed that women who had a higher number of traumatic experiences had poorer endothelial function, making them more susceptible to a cardiac incident.

"These findings underscore the importance of psychosocial factors, such as trauma exposure, in the development of heart disease risk in midlife women," said lead author Dr. Rebecca Thurston.

The findings of the study will be presented at <a href="http://www.menopause.org/">The North American Menopause Society</a> (NAMS) Annual Meeting in Philadelphia, October 11-14. Dr. JoAnn Pinkerton is the executive director of NAMS.

"Given the large percentage of postmenopausal women affected by heart disease, this is an important study that should remind healthcare providers of the need to thoroughly discuss a woman's history beyond simply asking about her physical health," said Dr. Pinkerton.

A new study has found that men spend more leisure time than their partners during the first few months of taking care of a new baby. 

The study was conducted by researchers at <a href="https://www.osu.edu/">Ohio State University</a> and was published online in the journal Sex Roles. 

The study is one of the first of its kind to show physical evidence of what roles <a href="https://www.earth.com/news/marriage-forgiveness-self-restraint/">men and women</a> often take after the birth of a child, and how household work and childcare are unequally shared. 

“It's frustrating. Household tasks and childcare are still not being shared equally, even among couples who we expected would have more egalitarian views of how to share parenting duties,” said Claire Kamp Dush, the lead author of the study and associate professor of human sciences at Ohio State University.

For the study, the researchers asked 52 expecting couples who had participated in the New Parents Project, an Ohio State study of educated, white dual-earner couples from Columbus Ohio, to record their day to day activities in a journal before and after their baby was born. 

The limited nature of the diversity represented in the couples doesn’t give a complete representation of all couples in the area, but it does show some disparity between housework and childcare. 

On average, women spent less time relaxing than men. If the men were doing housework or childcare, women spent around 46 to 49 minutes relaxing, while men spent 101 minutes relaxing while the women worked. 

Interestingly, on workdays, the results showed that work and childcare were distributed more evenly, but on non-workdays women still took on the brunt of both. 

“On workdays, parents are more evenly splitting housework and childcare. It's very much ‘all hands on deck, ’ but when there is more time available on the weekend and parents are not so pressed to get everything done, then we see the emergence of gendered patterns and inequality," said Jill Yavorsky, an assistant professor of sociology at the <a href="http://www.unc.edu/">University of North Carolina at Charlotte</a> and fellow researcher of the study. 

The results surprised the researchers as Kamp Dush had expected to see more of an equal distribution of housework and childcare in the modern, dual-earning couples they had asked to participate. 

The solution to breaking these molds and habits is communication and asking the men to take on more responsibility. 

“Couples need to be having conversations, ideally before their baby is born, about how they are going to divide household tasks to make sure they are equitable,” Kamp Dush added.

Even in modern couples, women do more around the house

A new study has found that men spend more leisure...

A new study from the <a href="http://www.apa.org/">American Psychological Association</a> suggests that the best way to understand how someone is feeling is to use your ears and not your eyes. The research reveals that emotions can be discerned more accurately through vocal cues instead of facial expressions.

"Social and biological sciences over the years have demonstrated the profound desire of individuals to connect with others and the array of skills people possess to discern emotions or intentions. But, in the presence of both will and skill, people often inaccurately perceive others' emotions," said co-author Michael Kraus. "Our research suggests that relying on a combination of vocal and facial cues, or solely facial cues, may not be the best strategy for accurately recognizing the emotions or intentions of others."

For their study, researchers developed a series of five evaluations and enlisted over 1,800 participants from the United States. In each experiment, the individuals either interacted with another person or were presented with an interaction between two other participants. 

Sometimes the volunteers were able to hear but not watch the interactions, while other times they were only able to watch but not listen. The subjects could both watch and listen during the remaining tests. As a control condition, participants listened to a computerized voice reading a transcript of an interaction, which removed the emotional inflection of human communication from the scenario.

Overall, individuals who only listened to interactions without watching most accurately identified the emotions being experienced by others. The only exception was when subjects were presented with the computerized voices, which resulted in the least accuracy. 

"I think when examining these findings relative to how psychologists have studied emotion, these results might be surprising. Many tests of emotional intelligence rely on accurate perceptions of faces," he said. "What we find here is that perhaps people are paying too much attention to the face--the voice might have much of the content necessary to perceive others' internal states accurately. The findings suggest that we should be focusing more on studying vocalizations of emotion."

The findings of this study, which is published in the journal <a href="http://www.apa.org/pubs/journals/amp/">American Psychologist</a>, indicate that improving our listening skills could also improve our overall <a href="https://www.earth.com/news/cites-highest-quality-life/">quality of life</a>.

"Actually considering what people are saying and the ways in which they say it can, I believe, lead to improved understanding of others at work or in your personal relationships."

The female brain is wired to be more generous

A study from the University of Zurich provides new insight...

Data from the <a href="http://www.who.int/en/">World Health Organization</a> (WHO) shows that 361,000 children die every year from diarrheal disease that occurs as a result of poor access to clean water, sanitation, and hygiene. In fact, according to WHO, 1 in 4 deaths of children under 5 years old are attributed to unhealthy environments.

What these stats show is that access to <a href="https://www.earth.com/news/worlds-tap-water-contains-plastics/">clean drinking water</a> is of the utmost importance to the lives and overall health of children across the world. Knowing this, researchers are constantly looking to find what factors lead to unhealthy drinking water and how this can be better managed.

A study from the <a href="http://www.uvm.edu/">University of Vermont</a> of 300,000 children in 35 countries recently found that kids whose watersheds have more tree cover are less likely to get diarrheal disease – which is the second leading cause of death for children under five. This study is the first to quantify the connection between watershed quality and the individual health outcomes of children on a global scale.

“Looking at all of these diverse households in all these different countries, we find the healthier your watershed upstream, the less likely your kids are to get this potentially fatal disease,” says Taylor Ricketts of the <a href="http://www.uvm.edu/">University of Vermont</a> (UVM).

The research team believes that a 30 percent increase in upstream tree cover in rural watersheds could have a comparable effect to improved water sanitations, such as the addition of indoor plumbing or toilets.

“We are not saying trees are more important than toilets and indoor plumbing,” says Diego Herrera, lead author of the paper and a former UVM postdoctoral researcher. “But these findings clearly show that forests and other natural systems can complement traditional water sanitation systems, and help compensate for a lack of infrastructure.”

This study shows that protecting trees and watersheds can also double as a public health investment, as well as an investment in protecting our environment. The researchers hope that governments and development agencies will use these findings to improve the health and environment of children around the world.

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.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.

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

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://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.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."

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.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes a new map of Mars that is providing insight into the planet’s watery past. The map also reveals where future missions could safely land on Mars.&nbsp;



The map has been created over the last decade using observations of water-rich rocks and mineral deposits. The images were captured by ESA’s Mars Express and NASA’s Mars Reconnaissance Orbiter.



"A big surprise is the prevalence of these minerals, with the map revealing hundreds of thousands of water-affected locations in the oldest parts of the planet," says ESA. "The new data will help answer exciting questions about Mars’ climate history, whether water was globally persistent or confined to short, intense episodes, and whether the conditions were ever suitable for life."



"Specifically, the map shows the locations and abundances of aqueous minerals. These are from rocks that have been chemically altered by the action of water in the past, and have typically been transformed into clays and salts."



According to John Carter of the Institut d’Astrophysique Spatiale (IAS), our collective understanding of Mars has been oversimplified. He explained that planetary scientists have tended to think that only a few types of clay minerals on Mars were created during its wet period, then as the water gradually dried up, salts were produced across the planet.



The new map shows that the composition of Mars is much more complicated than what we thought. For example, while many salts formed after Martian clays, there are some salts that are presumed to be older than some of the clays.&nbsp;



“The evolution from lots of water to no water is not as clear cut as we thought, the water didn’t just stop overnight. We see a huge diversity of geological contexts, so that no one process or simple timeline can explain the evolution of the mineralogy of Mars. That’s the first result of our study. The second is that if you exclude life processes on Earth, Mars exhibits a diversity of mineralogy in geological settings just as Earth does,” said Carter.

Today's Video of the Day from the <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes how cavefish adapted to a sedentary lifestyle over tens of thousands of years. 



The experts found that the muscle metabolism of cavefish has been genetically reprogrammed over time. As a result, the animals have experienced major changes in their morphology and behavior. Despite these changes, however, the cavefish remain healthy and fit.



The research may provide new clues about the evolutionary consequences of prolonged physical inactivity in humans.&nbsp;



“It’s no surprise that people are moving less and less as technology has advanced,” said Rohner. “With cavefish, we have a unique system where we can study what might happen if people remained couch potatoes over very, very long periods of time.”

"With more than 370,000 miles of coastline on Earth, there are plenty of places where epic waves build up, curl over, and hurtle toward the shore.- much to the thrill of surfers," says NASA. "There are some places where these waves are so magnificent that they can be seen from space."



"With the broad perspective of satellites, we can see how these iconic waves develop into the world’s tallest, longest, fastest, and heaviest."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes why satellite images and measurements of our planet have become "essential to our survival, offering a new outlook of our world."&nbsp;



Rising sea levels pose one of the biggest societal threats associated with climate change. According to ESA, satellite altimeter missions such as Copernicus Sentinel-6 are essential in monitoring global and regional changes in sea level.



"Unbeknown to many, the island of Crete, Greece, plays an important role in the Copernicus satellite altimetry constellation and on an international stage," reports ESA.



"Satellite altimetry data have to be continuously monitored at the ESA’s Permanent Facility for Altimetry Calibration where different techniques have pioneered the use of transponders to provide the best measurements to validate satellite altimeters in space soon after launch."



Dr. Craig Donlon explains that, by understanding planet Earth through satellite measurements, we are able to find evidence of change.&nbsp;
