Wish,To,Meet,Santa,Claus.,Merry,Christmas,And,Happy,New

Every December, colorful lights and festive tunes remind kids, and adults, that Santa Claus is on his way. Families fill their homes with decorations, children write wish lists, and a sense of anticipation hangs in the air. 



Parents have long told their kids that if they behave well, Santa will bring them just what they asked for. Until recently, few studies examined whether this belief actually influenced how kids act.



In a new project, researchers decided to see if <a href="https://www.earth.com/news/irregular-bedtimes-disrupt-the-well-being-and-behavior-of-children/" target="_blank" rel="noreferrer noopener">children</a> truly become more considerate when they think Santa is watching. 



They explored whether kids act better because of the story of Santa or because of everything else going on during the holiday season. 



Professor Kapitány from the <a href="https://www.ox.ac.uk/" target="_blank" rel="noreferrer noopener">University of Oxford</a> led the investigation along with colleagues from <a href="https://www.durham.ac.uk/" target="_blank" rel="noreferrer noopener">Durham</a>, <a href="https://www.ed.ac.uk/" target="_blank" rel="noreferrer noopener">Edinburgh</a>, and <a href="https://www.leeds.ac.uk/" target="_blank" rel="noreferrer noopener">Leeds</a>.



<h2 class="wp-block-heading" id="h-kids-santa-and-surprises">Kids, Santa, and surprises</h2>



The study tracked 533 kids between ages four and nine over three separate Christmases and visits from Santa. Families <a href="https://www.earth.com/news/kids-with-behavioral-issues-have-high-cortisol-levels-in-their-hair/" target="_blank" rel="noreferrer noopener">reported on behaviors</a> like sharing, helping others, and following rules. 



Parents also described whether their kids believed in Santa and took part in festive traditions. According to the data, there was no direct link between Santa belief alone and an increase in kindness.



Instead, good behavior rose as Christmas neared when families engaged in activities such as decorating their homes, singing carols, and enjoying special treats.&nbsp;



The study noted that these experiences led to small but consistent boosts in generous and <a href="https://www.earth.com/news/kindergarten-conduct-childhood-behavioral-problems-will-cost-society-later/" target="_blank" rel="noreferrer noopener">respectful actions</a>. 



This shift also came with a bump in more rowdy moments, highlighting that heightened excitement can show up in many ways.



<h2 class="wp-block-heading" id="h-the-power-of-festive-rituals">The power of festive rituals</h2>



For many families, hanging ornaments or baking Christmas cookies is more than just a fun holiday pastime. 



These rituals offer children a chance to feel a sense of togetherness and excitement that breaks up their usual routine. 



The study suggests that these shared activities have a greater <a href="https://www.earth.com/news/children-consider-their-own-past-actions-before-judging-others/" target="_blank" rel="noreferrer noopener">effect on kindness</a> than the idea of being judged by a mysterious gift-giver in a red suit.



Parents often say they remind kids to be on their best behavior so Santa will reward them. Yet the findings show it’s the holiday atmosphere itself that has the strongest pull. 



One researcher described it by saying “the magic is in the time of year, so to speak, not in the claim over the supernatural big man.”



<h2 class="wp-block-heading" id="h-supernatural-beliefs-and-morality">Supernatural beliefs and morality</h2>



Some scholars point out that Santa is often placed on the same pedestal as other powerful beings in certain cultures. 



Parents treat him as a figure who can watch children from afar, keep track of good deeds, and decide on gifts. 



This study adds to conversations about how belief in unseen forces might shape moral choices.



Other work shows that religious ideas can sometimes bring out prosocial behavior. Hearing about rules or promises of rewards can prompt more cooperation.&nbsp;



In the case of Santa, though, the results suggest that the presence of traditions might play a bigger role in guiding kids toward friendly, generous actions.



<h2 class="wp-block-heading" id="h-contrasting-philosophies-on-kids-and-santa">Contrasting philosophies on kids and Santa</h2>



Philosophers have different views on whether parents should even promote Santa’s story. 



Dr. Joseph Millum from the <a href="https://www.st-andrews.ac.uk/" target="_blank" rel="noreferrer noopener">University of St. Andrews</a> worries it “breaches trust,” calling Santa a “preposterous lie.” Others feel that Santa can be a healthy way to bring joy into children’s lives. 



Tom Whyman, a lecturer in philosophy at the <a href="https://www.liverpool.ac.uk/" target="_blank" rel="noreferrer noopener">University of Liverpool</a>, says that “kids need Santa.” 



These opinions highlight the varying attitudes people have toward a figure whose influence has become an enduring feature of holiday culture.



When parents choose whether to encourage this tale, they grapple with how it shapes their children’s sense of wonder and truth. 



Some families see Santa as <a href="https://www.earth.com/news/pretend-play-builds-the-foundation-for-learning-and-relationships/" target="_blank" rel="noreferrer noopener">harmless make-believe</a>, while others wonder if creating a magical visitor might later undermine a child’s trust. 



The study reminds us that cultural myths carry weight, yet they may not fully explain shifts in children’s behavior.



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



The research shows that singing festive songs, <a href="https://www.earth.com/news/christmas-trees-have-unique-strategies-to-survive-freezing-winters/" target="_blank" rel="noreferrer noopener">placing ornaments on a tree</a>, or preparing traditional foods creates a distinct environment. That environment is linked with both extra kindness and occasional bursts of negative behavior. 



While the belief in Santa himself did not correlate directly with improved conduct, the coordinated celebration of the season proved to be more powerful.



Families can consider how these moments <a href="https://www.earth.com/news/personality-traits-are-not-strongly-inherited-from-parents/" target="_blank" rel="noreferrer noopener">bring the household closer</a>. Children who help bake cookies or watch a classic Christmas movie often feel a greater sense of involvement. 



This sense of participation aligns with the study’s findings that holiday events can be a driving force behind thoughtful gestures, cooperation, and cheer.



<h2 class="wp-block-heading" id="h-bigger-questions-about-childhood-and-culture">Bigger questions about childhood and culture</h2>



Santa’s modern image traces back to a blend of folklore, marketing campaigns, and traditions inspired by Saint Nicholas. 



For countless children, the idea of a kindhearted figure traveling the skies in a single night is a highlight of December. 



This study encourages us to think about how such stories fit into broader questions about parenting approaches and cultural myths. 



Many communities celebrate special figures who reward the nice and ignore or punish the naughty. 



In each case, children experience stories they can hold onto, if only for a few magical years. The current research suggests that these stories may matter less than the rituals and music, but they still add color to the season.



<h2 class="wp-block-heading" id="h-why-does-any-of-this-matter">Why does any of this matter?</h2>



Plenty of families continue to share the Santa story, watch Christmas movies, and maintain lively traditions. 



The researchers point out that more studies could explore how different cultural celebrations, and the potential <a href="https://www.earth.com/news/holiday-stress-is-higher-this-year-compared-to-2023/" target="_blank" rel="noreferrer noopener">stress levels surrounding them</a>, ultimately help shape child development. 



From the outside, it might seem obvious that gatherings, songs, and decorations encourage bright and kind behavior, yet measuring these elements takes careful planning.



Some psychologists are curious about whether similar patterns show up around other holidays or special events with strong rituals.&nbsp;



The core message remains that communal practices, family bonding, and joyful anticipation often spark gentler and more considerate behavior in children. 



The Santa myth is part of that puzzle, but it may not be the only factor making kids play nicely.



<h2 class="wp-block-heading" id="h-what-did-we-learn-about-kids-and-santa">What did we learn about kids and Santa?</h2>



The takeaway here is that Christmas is a powerful backdrop for <a href="https://www.earth.com/news/many-parents-use-threats-to-discipline-children-but-its-not-effective-in-the-long-run/" target="_blank" rel="noreferrer noopener">shaping how children behave</a>. 



A lively household filled with festive foods, carols, and colorful decorations can steer kids toward more thoughtful choices, even if the well-known Santa story doesn’t stand alone as a motivator. 



Traditions that families share appear to matter more than the promise of presents under the tree.



These observations offer a new way to think about how myths and rituals come together to create a meaningful holiday experience.&nbsp;



Children may still look forward to Santa’s arrival each year, but the real spark for positive behavior lies in those precious moments spent enjoying the season.

Does believing in Santa make kids behave better? A new study found out

Every December, colorful lights and festive tunes remind kids, and adults, that Santa Claus is on his way. Families fill their homes with decorations, children write wish lists, and a sense of anticipation hangs in the air.  Parents have long told their kids that if they behave well, Santa will bring them just what they asked for. Until recently, few studies examined whether this belief actually influenced how kids act. In a new project, researchers decided to see if children truly become more considerate when they think...

Protected areas within the United States account for roughly 14 percent of the country’s total landmass. They are integral for conservation of natural resources that would otherwise be used up or mowed down in the pursuit of building even more infrastructure.

Despite the protected status these areas have, they still face outside threats due to their proximity to human beings. Researchers have recently found that noise pollution around protected areas poses a threat to the refuge that these lands provide.

In a novel study, lead author Rachel Buxton – a post-doctoral researcher in the Department of Fish, Wildlife, and Conservation Biology at <a href="https://www.colostate.edu/">Colorado State University</a> – found that noise pollution was two times higher than background sound levels in a majority of U.S. protected areas. Her team also found a ten-fold or greater increase in noise pollution in 21 percent of protected areas.

This noise pollution is a result of expansion of human activities and nearby transportation networks. “The noise levels we found can be harmful to visitor experiences in these areas, and can be harmful to human health, and to wildlife,” says Buxton. The major causes of the noise were found to mainly be from roads, aircraft, human development, and resource extraction.

For this comprehensive study, the research team analyzed millions of hours of sound measurements from 492 sites within the continental U.S. They found that human-caused <a href="https://www.earth.com/news/traffic-noise-birds-stop-singing/">noise</a> doubled the level of background noise in 63 percent of protected areas. This also means that noise pollution reduced the area that natural sounds can be heard by 50 to 90 percent.

The mood enhancement and stress reduction that can come as a benefit of us humans spending time in nature is negatively impacted by these levels of noise, making a trip to these parks much less of the effective escape it’s meant to be. Noise pollution also negatively affects wildlife by scaring animals as well as distracting them. Scientists believe this can result in changes in species composition.

Significantly increased levels of noise pollution were also discovered to infiltrate the habitats of endangered species, mostly in endangered plant and insect habitats. “Although plants can’t hear, many animals that disperse seeds or pollinate flowers can hear, and are known to be affected by noise, resulting in indirect impacts on plants,” explains Buxton.

Luckily, some protected areas have already implemented noise-reduction strategies, starting shuttle services that reduce traffic and establishing quiet zones where park visitors are asked to quietly enjoy their natural surroundings. 

“Numerous noise mitigation strategies have been successfully developed and implemented, so we already have the knowledge needed to address noise issues,” says George Wittemyer, an associate professor at <a href="https://www.colostate.edu/">Colorado State University</a> and the senior author of this study. “Our work provides information to facilitate such efforts in respect to protected areas where natural sounds are integral.”

Hopefully this research will lead to more parks introducing plans to reduce surrounding noise pollution, allowing their visitors and wildlife to enjoy the real sounds of nature.

After many years of hearing how bad it is to utter profanities, people may now have good reason to swear. A new study, which is being revealed today at the Annual Conference of the British Psychological Society, proves that swearing makes people stronger. 

A team led by Dr. Richard Stevens of <a href="https://www.keele.ac.uk/">Keele University</a> conducted the project, which expanded on conclusions drawn from an earlier study. The team had previously established that swearing made people more tolerant of pain. 

“A possible reason for this,” said Dr. Stevens, “is that it stimulates the body's sympathetic nervous system - that's the system that makes your heart pound when you are in danger.”

The sympathetic nervous system responds to stress by releasing hormones that prepare the body for optimal performance. People experience a sudden burst of energy, also known as an adrenaline rush, when the sympathetic nervous system is initiated beyond its basic level of activity. The research team derived that if swearing does, in fact, stimulate the body's sympathetic <a href="https://www.earth.com/news/fish-nervous-systems-fin/">nervous system</a>, then swearing may also make people stronger.

The experts used an exercise bike to test the anaerobic power of 29 individuals under two different circumstances - after swearing and after not swearing. The same conditions were used for isometric handgrip testing of 52 individuals. The results of both tests showed that participants performed better after they had used bad language. After cursing, participants produced more energy in the energy-output tests and displayed more strength in the handgrip tests. 

The research team expected to find stimulation of the sympathetic nervous system responsible for the results of their study. However, Dr. Stevens explained that when the team looked for symptoms of an activated sympathetic nervous system such as accelerated heart rate and dilated pupils, there were no changes significant enough to support this conclusion. 

"So quite why it is that swearing has these effects on strength and pain tolerance remains to be discovered. We have yet to understand the power of swearing fully,” added Dr. Stevens.

A bionic hand fitted with a camera that allows the wearer to reach for objects without thinking, will be tested by patients at a British hospital.

“Using computer vision, we have developed a bionic hand which can respond automatically -- in fact, just like a real hand,” said Dr Kianoush Nazarpour, a  senior lecturer at <a href="http://www.ncl.ac.uk/">Newcastle University</a> and coauthor of a study on the device. “The user can reach out and pick up a cup or a biscuit with nothing more than a quick glance in the right direction.”

The hand has already been tested on a few amputees and now the Newcastle University team is working to offer the “'hands with eyes” to patients at Newcastle's Freeman Hospital.

The camera  “'sees” an object, picks the most appropriate grasp and sends a signal to the hand -- all within a matter of milliseconds and 10 times faster than any other limb currently on the market, the university said.

The work is part of a larger research project to develop a bionic hand that can sense pressure and temperature and transmit the information back to the <a href="https://www.earth.com/news/brain-creates-illusions/">brain</a>.

The goal is to develop electronic devices that connect to the forearm neural networks to allow two-way communications with the brain. The electrodes in the bionic limb would wrap around the nerve endings in the arm to establish direct communication between the brain and the prosthesis.

The “hand that sees” is an interim solution that will bridge the gap between current designs and the future, Nazarpour said.

"It's a stepping stone towards our ultimate goal," he says. "But importantly, it's cheap and it can be implemented soon because it doesn't require new prosthetics -- we can just adapt the ones we have."

A study on the new device is published in the <a href="http://iopscience.iop.org/journal/1741-2552">Journal of Neural Engineering</a>.

All it takes is 10 minutes of meditation a day to help prevent your mind from wandering, a new study found.

Daily meditation is particularly effective if you frequently have repetitive, anxious thoughts, according to the research by the <a href="https://uwaterloo.ca/">University of Waterloo</a> in Canada.

“Our results indicate that mindfulness training may have protective effects on mind wandering for anxious individuals,” said Mengran Xu, a researcher and PhD candidate at Waterloo. “We also found that meditation practice appears to help anxious people to shift their attention from their own internal worries to the present-moment external world, which enables better focus on a task at hand.”

Mindfulness is commonly defined as paying attention on purpose, in the present moment, and without judgment.

As part of the study, participants were asked to perform a task on a computer while experiencing interruptions to gauge their ability to stay focused on the task. Researchers then put the participants into two random groups with the control group given an audio story to listen to and the other group asked to engage in a short meditation <a href="https://www.earth.com/news/exercise-pill-form/">exercise</a> prior to being reassessed.

“Mind wandering accounts for nearly half of any person’s daily stream of consciousness,” said Xu. “For people with anxiety, repetitive off-task thoughts can negatively affect their ability to learn, to complete tasks, or even function safely.”

The study was co-authored by Waterloo psychology professors Christine Purdon and Daniel Smilek and <a href="http://www.harvard.edu/">Harvard University</a>’s Paul Seli, was published in <a href="https://www.journals.elsevier.com/consciousness-and-cognition/">Consciousness and Cognition</a>.

The scent of rosemary oil can improve working memory in children, a new study found.

Researchers Mark Moss and Victoria Earle of <a href="https://www.northumbria.ac.uk/">Northumbria Universit</a>y tested 40 children aged 10 to 11 on mental tasks. Children were randomly assigned to a room that had either rosemary oil diffused in it for 10  minutes or a room with no scent.

<a href="https://www.earth.com/video/children-crossing-street-safely/">Children</a> in the aroma room received significantly higher scores on a test to recall words than those in the non-scented room. 

"Why and how rosemary has this effect is still up for debate,” Moss said. “I could be that aromas affect electrical activity in the brain or that pharmacologically active compounds can be absorbed when adults are exposed.”

A previous study demonstrated that the smell of rosemary cognition in adults, prompting the new study on children. 

"We do know that poor working memory is related to poor academic performance and these findings offer a possible cost effective and simple intervention to improve academic performance in children, Moss said. “The time is ripe for large-scale trials of aroma application in education settings."

The study is scheduled to be presented Thursday at the <a href="http://www1.bps.org.uk/">British Psychological Society</a> annual Conference in Brighton, United Kingdom.

It’s almost <a href="https://www.earth.com/news/environmentally-friendly-cool-summer/">summer</a>, which means an increase in sun, fun, and… air pollution???

That’s right, because as the temperature rises what do we do? We crank up the air conditioner and bask in the glory of indoor cooling. But running these devices causes power plants to up their electricity production, leading to an increase in air polluting emissions.

Few studies have examined the specific effects of climate on electricity emissions and air quality, until now. In a comprehensive study of 27 states, researchers found that summer emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon dioxide (CO2) go up by hundreds to thousands of metric tons per degree Celsius increase.

But it’s not all bad – overall emissions have dropped as a result of pollution control devices and a reduction in coal use. However, seasonal increases in power plant pollution can still affect public health as well as the environment.

Sulfur dioxide and nitrogen oxides can both cause respiratory problems, and are regulated in the United States. These problems are exacerbated in children, people suffering from asthma, and the elderly.

Using data collected between 2003 and 2014, researchers Tracey Holloway and David Abel looked to quantify the historical relationship between summertime air temperatures and power plant emissions of SO2, NOx, and CO2. This data contained numbers on the electricity emissions in 27 states, mainly in the Eastern U.S.

In their analysis, the researchers found that power plants released over 3 percent more SO2, NOx, and CO2 on average per degree Celsius increase in air temperature. The biggest contributors in the SO2 division were states like Ohio, Indiana, and Pennsylvania, where coal power plays a big part in the energy grid. States like Texas with a large power demand were found to have high emissions of all pollutants, but smaller changes in emissions per degree Celsius. Ultimately, the researchers found that these increases in summertime air temperature are correlated with an additional 140,000 metric tons of CO2 emissions. 

This area of research will hopefully lead to an increase in the energy efficiency of new buildings, and could also play a much needed role in decreasing power plant emissions, which will improve our air quality for the future.

More information on this study can be found in the journal <a href="http://pubs.acs.org/journal/esthag">Environmental Science &amp; Technology</a>.

Babies born to fathers under the age of 25 or over 51 may influence their social development, a new study says.

The study by the <a href="http://icahn.mssm.edu/research/seaver">Seaver Autism Center for Research and Treatment</a> at Mount Sinai, found the <a href="https://www.earth.com/video/children-crossing-street-safely/">children</a> may be more advanced than their peers as infants, but then fall behind by the time they hit their teenage years.

The researchers analyzed 15,000 UK-based twins aged between four and 16. 

In order to learn whether children's social skills were affected by how old their father was when they were born, the team looked for differences in the developmental patterns of social skills, as well as other behaviors, including conduct and peer problems, hyperactivity, and emotionality. They also investigated whether the effects of paternal age on development were more likely attributable to genetic or environmental factors.

“Our results suggests that children born to very young or older fathers may find social situations more challenging, even if they do not meet the diagnostic criteria for autism,” said Magdalena Janecka, a Mount Sinai fellow.

The findings may offer insights into how paternal age influences children's risk of autism and schizophrenia, which was shown in earlier studies. 

The researchers found no link between the age of the mother and their offsprings’ social skill development. 

“Our study suggests that social skills are a key domain affected by paternal age,” Dr. Janecka  said. “What was interesting is that the development of those skills was altered in the offspring of both older as well as very young fathers.”

Researchers want to replicate those findings in further studies.

"Those developmental differences, if confirmed, are likely traceable to alterations in brain maturation," Dr. Janecka said. "Identifying neural structures that are affected by paternal age at conception, and seeing how their development differs from the typical patterns, will allow us to better understand the mechanisms behind those effects of paternal age, as well as, likely, autism and schizophrenia."

The study is published in the May issue of the <a href="https://www.aacap.org/">American Academy of Child and Adolescent Psychiatry</a>.

Emotional intelligence is the ability to identify the <a href="https://www.earth.com/news/dogs-mirror-owners-emotions/">emotions</a> of oneself and others. Self-awareness is a critical step in achieving this level of intellect. When you recognize your own emotions and how they affect your thoughts and behavior, you become more aware of the same emotional cues in others. Emerging research has taken this idea to a new level, and finds that tuning into your own body may allow you to read other people’s minds.

Punit Shah is a professor of psychology at <a href="http://www.anglia.ac.uk/">Anglia Ruskin University</a> who led the study. The main goal of the project was to determine if concentrating on oneself helps to better interpret what someone else is feeling. Shah suggested that when people notice their own heartbeat, it makes them more aware of the emotional states of others.

“If a male colleague is aggressive towards a woman on public transport, your body processes this by increasing your heart rate, perhaps making you feel awkward and anxious, enabling you to understand she is embarrassed. If you do not feel your heart rate increase, it may reduce your ability to understand that situation and respond appropriately,” explained Shah.

The research team asked participants of the study to focus on their heartbeats, and count their pulses without the use of equipment. Their level of accuracy was noted. Next, the individuals were shown short films of social interactions during which they were asked a series of questions. Some of the questions were pertaining to the thoughts and feelings of the characters, while others were irrelevant questions about the weather and backdrop.

The results of the study showed that the individuals who were more conscious of their heart rate seemed to also have a heightened state of perception. Those participants who most accurately reported their heart rate expressed much more insight in their responses regarding the emotions and feelings of the characters. The conclusion of this study suggests that teaching people to recognize their heart patterns may have some incredible benefits, such as helping people learn to deal with emotional problems.

“This may have a beneficial impact on daily functioning, where an improved ability to interpret the internal states of oneself and others could result in more accurate mind reading and improve someone’s social interactions and overall quality of life,” said Shah.

Sometimes, all it takes to be happy is a solid case of emotional exhaustion, a new study says. 

Research by the <a href="https://www.uea.ac.uk/">University of East Anglia </a>(UEA) suggests that the process of dealing with emotional exhaustion can sometimes increase <a href="https://www.earth.com/news/study-bees-emotions-good-food-makes-happy/">happiness</a>.

It’s the activity of searching for advice, support or information from others - that boosts happiness, according to the research.

The study examined the role of work supervisors in providing supportiveness, caring and appreciation for the efforts of an exhausted employee.

"It is important to note that it is not emotional exhaustion per se, but rather how people cope with it, that is beneficial for individuals,” said Carlos Ferreira Peralta of UEA's <a href="https://www.uea.ac.uk/norwich-business-school">Norwich Business School</a>. “Our findings suggest that the activities people engage in have a key role in building happiness from an internally stressful experience and that emotional exhaustion can have a silver lining."

 Employees who perceived that their supervisor is not supportive stimulated them to develop an action plan to searching for advice, support or information from others. It was these efforts that boosted happiness, the study said.

This is believed to be the first study to investigate how the connection between emotional exhaustion and happiness. Previous studies have highlighted the harmful consequences of emotional exhaustion, such as poorer performance and depression, and that supervisor support can prevent emotional exhaustion.

“This research contributes to a greater understanding of whether benefits can be gained by individuals as they cope with emotional exhaustion,” Peralta said.

The findings are published in the journal <a href="http://www.tandfonline.com/toc/twst20/current">Work &amp; Stress</a>

Fishing for “likes” on social media could indicate low self esteem, a new preliminary study says.

Also, likes don’t make people feel better about themselves or improve their <a href="https://www.earth.com/news/climate-change-mental-health-issues/">mood</a> if they are down, said the study, led by Dr Martin Graff from <a href="http://www.southwales.ac.uk/">University of South Wales</a>. 

Questionnaires provided to 340 participants on Twitter and Facebook asked them to say how much they agreed or disagreed with statements such as “'the attention I get from social media makes me feel good” or “I consider someone popular based on the amount of likes they get.”.

Participants who said they went out of their way to get more likes such as asking others or paying, were more likely to have low self-esteem and be less trusting, the study found. The same was true of those who admitted deleting posts or choosing their profile based on the number of likes it received.

 "The proliferation of social media use has led to general concerns about the effects on our mental health,” Graff said. “Although this is just a relatively small-scale study the results indicate that the ways we interact with social media can affect how we feel and not always positively."

The study is scheduled to be presented at the British Psychological Society's Annual Conference in Brighton, United Kingdom.

People who have a good memory grow tired of experiences faster, according to a new study which could help companies that market products to consumers.

"People with larger working memory capacities actually encode information more deeply," said Noelle Nelson, lead author of the <a href="https://www.ku.edu/">University of Kansas</a> study published in the <a href="http://www.ejcr.org/">Journal of Consumer Research</a>. "They remember more details about the things they've experienced, and that leads them to feel like they've had it more. That feeling then leads to the large-capacity people getting tired of experiences faster."

The study provides a window into how memory could be the key to becoming satiated, especially on products or habits they hope to quit, such as eating unhealthy foods, the study said.

"Our findings suggest that if they can enhance their memory for the other times they've eaten these foods, they may feel satiated and then not seek out those unhealthy things," said Nelson, an assistant professor of marketing and consumer behavior 

Nelson and coauthor Joseph Redden, associate professor of marketing at the <a href="https://twin-cities.umn.edu/">University of Minnesota</a>, conducted four experiments with undergraduates They measured students’ working memory capacities in different ways, such as how well they could remember a string of letters.

Then participants then performed a task where they would eventually become tired of what they experienced, like viewing paintings or listening to music.

Marketers might be able this type of research to craft strategies on ways to keep people interested longer.

"For example, introducing new products or having distractions in ads might help break up the satiation process because they disrupt memory," Nelson said.

The researchers didn't specifically study overeating or unhealthy <a href="https://www.earth.com/news/14-billion-dollars-edible-foods-trashed/">foods</a>, but the findings should extend to those types of experiences, she added.

"Because a big part of overeating is psychological, a psychological solution such as memory processes, could help people control their eating," Nelson said. "Consumers might be able to satiate more quickly by simply recalling the last several times they ate."

Sunscreen could be killing <a href="https://www.earth.com/news/fish-saving-coral-reefs/">coral reefs</a> surrounding Hawaii’s eight main islands, and Hawaii may be gearing up to do something about it.

Earlier this year, Hawaii state senator Will Espero introduced a bill that would ban the sale of sunscreens containing the chemical oxybenzone within the state. According to <a href="http://www.popsci.com/">Popular Science</a>, “there’s a reasonably good chance it will pass and become law.”

Espero and others became concerned about sunscreen  on the strength of a few studies, most recently a 2015 paper in the journal<a href="https://link.springer.com/article/10.1007/s00244-015-0227-7"> Environmental Conamination and Toxicology</a> led by Craig Downs, executive director of the <a href="http://www.haereticus-lab.org/">Haereticus Environmental Laboratory</a> in Clifford, Va.

Oxybenzone is toxic to the symbiotic algae that live within coral, Downs found.. In addition to giving coral their colored appearance, the algae also provide the coral with much needed oxygen and help cart away the coral’s waste, the magazine said.

When the algae die off, the corals turn white (referred to as bleaching), which is a dire sign—with less oxygen and more waste, the coral struggles to survive. Oxybenzone is more toxic to plants when those plants are exposed to sunlight. 

When coral cells are exposed to oxybenzone, it damages their DNA—causing harmful mutations. It also causes young coral to harden, essentially trapping them in their own skeletons and killing them. Oxybenzone can kill at least seven different types of coral, and it only takes: a single drop in 4.3 million gallons of water—six and a half Olympic sized swimming pools to be deadly. According to Downs, an estimated 6,000 to 14,000 tons of sunscreen lotion are released into coral reef areas each year.

A 2007 study conducted by researchers at the <a href="https://www.plymouth.ac.uk/">University of Plymouth</a> and published in the journal Applied and Environmental Microbiology found that sunscreens cause the rapid and complete bleaching of hard corals even at very low concentrations.

Those result were mirrored in a 2008 study, published in the journal <a href="https://ehp.niehs.nih.gov/">Environmental Health Perspective</a>, conducted by researchers from the <a href="http://www.univpm.it/English/">Polytechnic University of the Marche</a> in Ancona, Italy.

Other places have banned the use of chemical sunscreens specifically near reefs, including Xel-Ha in Cancun’s Riviera Maya. But Hawaii’s ban, if successful, would be unusual for its scale—it would be statewide, across all of the islands, affecting even those who may never set foot in the ocean, Popular Science reported.

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."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes a new self-powered nanosensor that can instantly detect mercury contamination with the tap of a finger.&nbsp;



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;

'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.

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."

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;

Satellites reveal how Earth's systems are interconnected

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.”

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> some of the most incredible waves in the world, as seen by Landsat satellites.



"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;
