Patience is often regarded as a noble virtue, but its true essence may stem from how we handle life's relentless challenges and frustrations.



Kate Sweeny, a psychology scientist at <a href="https://www.ucr.edu/" target="_blank" rel="noreferrer noopener">UC Riverside</a>, suggests that patience might be less about our moral standing and more about how we handle the everyday irritations that life throws at us.



"Philosophers and religious scholars call patience a virtue, yet most people claim to be impatient," said Sweeny. "That made me wonder if maybe patience is less about being a good person and more about how we deal with day-to-day frustrations."



Sweeny conducted a study that was focused on defining what encompasses patience and impatience, and the factors that contribute to them.



<h2 class="wp-block-heading" id="h-interpreting-patience-and-impatience">Interpreting patience and impatience</h2>



<a href="https://www.earth.com/news/why-humans-hate-to-wait-and-what-our-impatience-says-about-us/" target="_blank" rel="noreferrer noopener">Impatience</a>, according to Sweeny, is the emotion experienced when encountering delays that seem unfair, unreasonable, or inappropriate - like heavy traffic during off-peak hours or a meeting dragging on well past its scheduled time.



In contrast, patience is how individuals cope with these feelings of impatience. Psychologists often refer to "<a href="https://www.earth.com/news/study-pinpoints-the-brain-regions-that-regulate-emotions/" target="_blank" rel="noreferrer noopener">emotion regulation</a>" as the range of strategies people use to adjust the intensity of their emotions.



In a companion theoretical paper, Sweeny emphasizes that patience represents a specific subset of these strategies, focusing on managing feelings of impatience.



<h2 class="wp-block-heading" id="h-the-perfect-storm-for-impatience">The "perfect storm" for impatience</h2>



The researchers identified three scenarios that form the ideal recipe for impatience: a critical situation (like a traffic jam on the way to a favorite band's concert), an uncomfortable waiting state (like a packed waiting room at the DMV), and when there's an obvious person to blame for the delay (such as the lab forgetting to process your medical tests).



People felt more impatient when a delay lasted longer than expected, although the actual length of the delay did not significantly impact their feelings of impatience.



To explore these frustrations, participants were asked to imagine their reactions to everyday aggravations, such as being stuck in traffic, enduring a tedious meeting, or waiting in a crowded room.



The individuals assessed how impatient these situations would make them feel and identified strategies to temper their impatience, including distraction techniques, deep <a href="https://www.earth.com/news/breathing-exercises-improve-focus-in-children-with-adhd/" target="_blank" rel="noreferrer noopener">breathing exercises</a>, or finding a silver lining in the situation.



<h2 class="wp-block-heading" id="h-the-spectrum-of-patience">The spectrum of patience</h2>



Interestingly, not everyone responded to these irritation-causing situations in the same way. Some were more patient than others. For instance, individuals who were more adaptable to open-ended situations and more emotionally stable displayed less impatience.



Moreover, those who had higher <a href="https://www.earth.com/news/emotional-intelligence-may-be-secret-to-academic-success/" target="_blank" rel="noreferrer noopener">emotional intelligence</a> and were better at self-regulation were also more patient, even if they initially felt impatient.



"Our initial findings support many of our ideas about patience and impatience. We have a lot still to learn, but our approach is quite promising in terms of helping people to manage feelings of impatience and ultimately become more patient in their daily lives," noted Sweeny.



These findings present a fresh perspective on patience and impatience - not as intrinsic qualities of a person, but as responses and <a href="https://www.earth.com/news/people-who-are-connected-with-nature-have-better-coping-skills/" target="_blank" rel="noreferrer noopener">coping</a> strategies we embrace when faced with the inevitable irritations of life.



<h2 class="wp-block-heading" id="h-patience-and-personality-traits">Patience and personality traits</h2>



The research sheds light on how personality traits influence an individual's ability to remain patient. People who demonstrate greater emotional stability and adaptability in uncertain situations are less likely to feel overwhelmed by impatience.



Additionally, individuals with high emotional intelligence, who excel in self-regulation and empathy, tend to manage feelings of impatience more effectively. 



Traits like agreeableness also play a crucial role in encouraging patience, as such individuals often approach frustrating scenarios with a calm and understanding mindset.



These findings highlight that patience is not just situational but also deeply rooted in personal characteristics, offering a promising avenue for developing interventions to cultivate patience in daily life.



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



In an increasingly fast-paced world, the study’s findings have significant applications.



The ability to manage impatience effectively is crucial in both personal and professional settings. For instance, workplaces can benefit from training programs focused on emotion regulation techniques, helping employees cope with stress and maintain productivity during challenging times.



Moreover, understanding the psychology of patience can aid in conflict resolution by promoting empathy and cooperation. 



On an individual level, strategies like mindfulness, reframing negative situations, and practicing gratitude can be integrated into daily routines to enhance emotional well-being and cultivate a more patient approach to life.

Patience isn’t a virtue - it’s a coping strategy

Patience is often regarded as a noble virtue, but its true essence may stem from how we handle life's relentless challenges and frustrations.

Have you ever tried to change course midstream and found yourself unable to? For instance, say you notice a traffic light change yellow and decide to accelerate through, but then you see a police car, but you still speed through anyway because you weren’t quick enough to stop.

There’s a reason we can’t just instantly switch actions or stop a movement that we’ve already started, and neuroscientists from<a href="https://www.jhu.edu/"> John Hopkins University</a> have uncovered why.

Their new study, which was published in the journal Neuron, shows the inner workings of the brain as it sends and receives signals. 

The researchers found that a lightning fast interaction between three different parts of the <a href="https://www.earth.com/news/brain-processes-internal-experiences/">brain</a> is necessary to change or stop an action or behavior in process. 

Timing also played a major role in changing an action midstream, and the earlier you decide to change course, the better, according to the study.

“We have to process all of these pieces of information quickly,” said Susan Courtney, the senior author. “The question is: When we do succeed, how do we do that? What needs to happen in order for us to stop in time?”

It only takes a matter of milliseconds to go through with an action, and the research shows that if you can change your mind after 100 milliseconds or less, you can change or stop the plan.

The results could help with addiction treatments and understanding why people fall more as they get older.

For the study, the researchers had human and monkey subjects partake in an activity while their brains were monitored with MRI scanners. 

The activity involved shapes on a screen that were either blue, which meant stop or yellow which meant go. Another set of shapes used the same colors but they had the opposite meanings. The subjects followed the shapes and had to change directions or stop their already planned eye movements.

The MRI scans allowed the researchers to see how the brain processed information and quick changes while the subjects followed the shapes on the screen. 

Electrodes were implanted in the monkey subjects brain which gave the researchers a closer look at how different areas of the brain communicate with each other to stop. 

After monitoring the brain activity and analyzing the results, the researchers found that when the different parts of the prefrontal and pre-motor cortex didn’t communicate correctly or interact quickly enough, then the participants couldn’t change or stop a planned action or behavior.

Because cognitive functioning deteriorates  as we age, slower communication between these areas of the brain could explain why elderly people are prone to falling.

“We know people with damage to these parts of the brain have trouble changing plans or inhibiting actions,” Courtney said. “We know as we age, our brain slows down and it takes us longer to find words or to try to make these split-second plan changes. It could be part of the reason why old people fall.” 

The results could also better explain addiction behaviors and help people understand that the quicker you can “turn off” a thought about an addictive behavior like drinking, says Courtney, the more likely you will succeed in not following through on it.

Cities are beginning to turn to <a href="https://www.earth.com/news/easy-ways-adopt-zero-waste-mindset/">composting</a> as another means of keeping waste out of landfills, which also creates a nutrient-rich material that can be used for farming.

Composting comes with many benefits, but now new research has found that composting can lead people to make more eco-conscious decisions in their day to day lives. 

The study was led by Nicole Sintov, an Assistant Professor of Behavior, Decision-making and Sustainability at the <a href="https://www.osu.edu/">Ohio State University</a>. 

Sintov was interested to see if the adoption of a composting program would encourage area residents to make other smart “green” decisions” as part of something called “spillover.” 

Spillover is a concept where one behavior leads to another, either with positive or negative chain effects. For example, someone who decides to eat a salad for lunch might overcompensate for dinner. 

Sintov wanted to explore how spillover would apply to residents of Costa Mesa, California who in 2015 were given the option of curbside recycling and compost. 

“The idea is if you're investing all these resources - composting bins and trucks and new facilities - is it possible that this could lead to any other pro-environment behavior, or do people start to slack off in other areas, which we don't want,” said Sintov. 

The study included 284 Costa Mesa residents who were asked about three food-waste prevention behaviors and seven energy and water-waste behaviors, such as unplugging electronics and taking shorter showers. 

The results showed an increase in water and energy conservation behaviors that correlated with the start of the composting program. Composting was a catalyst that motivated other eco-friendly decisions. 

The researchers were happy to see that the spillover was largely positive. 

Sintov and her colleagues found that because those people that composted were actively engaged in waste disposal, they were more consciousness of waste in other aspects of their lives. 

“Our study found that this happened because waste was on their minds, or 'cognitively accessible,' and this thinking about waste seems to lead you to manage waste in other ways,” said Sintov. 

The study does not represent a wide range of residents, as the participants for the study all came from one affluent and well-educated community. The researchers note that further studies will need to be done to see if the results are duplicated in different communities and populations. 

Even with this in mind, the results present convincing evidence that composting programs have added eco-friendly benefits beyond reducing waste in landfills.

An ongoing <a href="https://www.npr.org/">NPR</a> series titled “Discrimination in America” takes an in-depth look at the discrimination and harassment that many Americans face on a daily basis. The series is based on a survey conducted for the <a href="https://www.npr.org/">National Public Radio</a>, the Robert Wood Johnson Foundation, and <a href="https://www.hsph.harvard.edu/">Harvard T.H. Chan School of Public Health</a>.

The most recent installment in the series examines the <a href="https://www.earth.com/news/economic-hardship-racial-discrimination/">discrimination</a> faced by Asian Americans and included responses from 500 Asian American U.S adults. 

At least 25 percent reported personal discrimination based on their race when applying for jobs, trying to get equal pay, or trying to rent or buy a home.

Almost 1 in 5 Asian Americans said they were discriminated against when applying to or attending college. 

18 percent felt discriminated against while interacting with police, and 12 percent reported they or a family member were stopped or mistreated both in the court system and by police because they were Asian. 

Indian Americans, on the other hand, reported higher instances of unfair police treatment and were stopped on average 17 percent more than Chinese Americans. 

It doesn’t stop there, with one-third of the survey respondents having experienced racial slurs or comments directly targeting their ethnicity. 

21 percent of Asian Americans reported that they have been threatened or harassed and 10 percent say they or a family member dealt with violence. 

When seeking medical treatment, almost 1 in 10 Asian Americans said at one time or another that they avoided seeking health care or going to a doctor due to the concern that they would be discriminated against. 

Higher income Asian Americans report fewer instances of unfair treatment by medical professionals, but the survey results showed that regardless of income, Asian Americans experience discrimination in nearly all facets of their lives. 

"Our poll shows that Asian American families have the highest average income among the groups we've surveyed, and yet the poll still finds that Asian Americans experience persistent discrimination in housing, jobs, and at college,” said Robert Blendon, the co-director of the survey.  “Over the course of our series, we are seeing again and again that income is not a shield from discrimination.”

The old adage “It’s not what you say, but how you say it,” has an even greater meaning when it comes to the acoustics of political speeches, as they can be a significant influencer on voter preferences. Recent research has found that vocal disorders – which change the qualities of a person’s speech – can have a big effect on a politician’s perceived charisma as well as a listener’s voting preferences.

For their study, researchers Rosario Signorello and Didier Demlin of the <a href="http://www.univ-paris3.fr/">Université Sorbonne Nouvelle, Paris</a>, analyzed two cases of politicians with vocal disorders. The first case was of Umberto Bossi, the former leader of the Italian Lega Nord party, who suffered a stroke that partially paralyzed his vocal cords. The second case was the former president of Brazil, Luiz Inácio Lula da Silva, whose larynx was damaged as a result of throat cancer.

In both cases, the pitch of the individual’s voice was lowered and their vocal range was narrowed. Their voices were also hoarse and they had a slower speech rate, as well as a lack of ability to modulate pitch. “We use pitch manipulation to be ironic and sarcastic, to change the meaning of a sentence,” explains Signorello. “Before the stroke, people perceived Bossi as positive, enthusiastic, a very charming speaker, and when listening to his post-stroke voice, everything changed. After the stroke, he had a flat pitch contour, a lack of modulation, and this was perceived as a wise and competent charisma."

The researchers called upon French participants –who  did not speak the language of the politicians – to assess which vocal stimuli they would vote for. The purpose of using an audience that didn’t understand the languages was that the researchers wanted the listeners to only pay attention to the acoustics, and not the verbal content.

For the French participants, the results surprisingly showed that they had a preference for both leaders’ post-disorder voices. “French people didn’t want to vote for someone who was strong and authoritarian, or perceived as a younger version of the leader," says Signorello. However, this trend was not exactly consistent. “In each example the vocal patterns are so diverse you never find the same answers; all trigger different emotional states and convey different personality traits,” explains Signorello.

The researchers emphasize that there is no “best” voice, pointing to the subjectivity of charisma. “Charisma is a social phenomenon,” says Signorello, “difficult to assess because it is subject to social trends. It’s impossible to give a recipe of what is more or less charismatic – it’s like fashion, it changes drastically with time.”

Even more interesting, the post-vocal disorder vocal stimuli were characterized by the listeners as having personality traits similar to those used to describe an older person (i.e. wise). The researchers plan on investigating this further, as well as extending the study to vocal disorders of female <a href="https://www.earth.com/news/politicians-get-away-lying/">politicians</a> and using their findings to help improve speech rehabilitation.

Cancer becomes an ever increasing risk as we age, and the association of old age with many cancer types has been well established. But scientists have also noticed that cancer incidence is increasing globally, and certain geographical populations seem to be at higher risk than others. Populations living in very low temperatures, such as Denmark and Norway, have some of the highest incidences of cancer in the world.

A recent paper published in the journal <a href="https://academic.oup.com/mbe">Molecular Biology and Evolution</a> has proposed a new hypothesis for this phenomenon: there is an evolutionary relationship between adaptation at extreme environmental conditions and increased cancer risk. 

“The findings of this study provide evidence that genetic variants found to be beneficial in extreme environments, can also predispose for cancer,” says Kostantinos Voskarides of the <a href="https://www.ucy.ac.cy/medical/en/">University of Cyprus Medical School</a>.

In his research, Voskarides focused on the effect of low temperatures at either high altitudes or in Arctic/Scandinavian climates. He used the GLOBOCAN-2012 database – the most accurate and reliable datasource for worldwide cancer incidence – and analyzed genetic clues in 247 different cancer genome-wide association studies. Voskarides also looked through the available literature’s bibliographic cancer incidence and genetic data for human populations in extreme cold and at very high altitudes.

The results showed a clear pattern, with the highest incidence of certain cancers linked to populations living in the coldest environments. 

“These data show that these populations exhibit extremely high cancer incidence, especially for lung, breast and colorectal cancer,” explained Voskarides.

Genetic evidence also showed that genes that are under selection to populations in order to survive in extreme conditions are also predisposed for cancer. The highest cancer associations with genes under selection were found to be colorectal cancer for Native Americans and Siberian Eskimos, esophageal cancer and lung cancer for Siberain Eskimos, leukemia for Oromi (a high-altitude population in Ethiopia) and a number of cancers for high-altitude dwelling Andeans-Tibetans.

“Evidence was found that cancer rates have been increased in those populations through natural selection procedures,” says Voskarides. “This is the first study that provides evidence that high cancer risk may be a result of evolutionary adaptation in certain environmental conditions.”

The ultimate conclusion of this study was that populations that are isolated in extreme environments also face extreme <a href="https://www.earth.com/news/cancer-cases-modifiable-risk-factors/">cancer</a> risk. Further research will help better understand the key adaptive forces that may be behind cancer epidemiology.

Fast-moving wildfires are raging across southern California, forcing the evacuation of tens of thousands of people. The Thomas Fire in Ventura County, which broke out on Monday and now covers at least 65,000 acres, is by far the largest. Over 150 buildings have been destroyed and 12,000 additional structures are currently threatened in Ventura alone.

In Los Angeles County, two separate fires ignited on Tuesday. North of downtown <a href="https://www.earth.com/news/watering-lawns-lost-gallons-water/">Los Angeles</a>, the Creek Fire burned 11,000 acres by Tuesday night, and the Rye Fire scorched 7,000 acres. 

A third fire, the Skirball Fire, erupted this morning near the Getty Center as a brush fire. This latest blaze has prompted evacuations from the Bel Air area and shut down portions of Interstate 405 because the fire is burning so close to the highway.

California Governor Jerry Brown has declared a state of emergency in both Ventura and Los Angeles counties, and is urging residents to be ready to evacuate and to “evacuate immediately if told to do so.”

Officials are warning that the fires could threaten the region for days. Los Angeles police chief Charlie Beck referred to the fires as “a multi day event,” and suggested that more fires are likely. 

The National Weather Service warned that the combination of low humidity and strong winds could lead to “very rapid fire growth” and “extreme fire behavior.”

Chief Ralph M. Terrazas of the Los Angeles Fire Department said earlier today that wind conditions are favorable at this time but warned that could change. Santa Ana winds are projected to reach 80 miles per hour on Thursday.

Just two months ago, Northern California experienced the worst series of wildfires in the state’s history, which killed 44 people and burned 8,700 structures.

Researchers at the <a href="http://www.cdb.riken.jp/en/">RIKEN Center for Developmental Biology</a> (CDB) set out to determine how the brain distinguishes between breathing in air and sniffing. The team also set out to solve the mystery of how sniffing helps to identify odors. 

Each compound in a scent activates certain neurons in the nose, which meet in the olfactory bulb of the brain on structures called glomeruli. For example, the smell of <a href="https://www.earth.com/news/chocolate-red-wine-wrinkles/">chocolate</a> will activate "chocolate" glomeruli. 

Neurons in the nose also respond when air is inhaled, but the activation is not as specific. Therefore, sniffing activates both "chocolate" and "non-chocolate" glomeruli. 

But how can the brain tell whether signals received from the glomeruli contain air-flow information or odor information? The study revealed that the answer lies in the timing.

"Surprisingly, we found that temporal firing patterns of neurons can distinguish between airflow-driven mechanical signals and those generated by odors,” explained lead author Takeshi Imai. “Not only that, we discovered that the mechanosensation actually improves olfaction by acting as a pacemaker for temporal patterning."

The team created a system to artificially control rhythmic sniffing in mice. In the first phase of the experiment, they presented deodorized air to the mice and recorded activity from neurons in the glomeruli. 

This showed that a large number of glomeruli were activated by airflow, and that the activity spiked and fell  in cycles that matched the rate of the artificial sniffing. But, despite the fact that the rate was the same, the glomeruli were not in sync with each other. While one glomerulus could be the most active 200 milliseconds into a sniff, another could be be most active 230 milliseconds after the sniff. 

Next, the team examined how increasing airflow and odor stimulation affected the phase of activity in the glomeruli. They found that increasing the airflow speed increased the amount of glomeruli activity, but did not significantly change their timing. On the other hand, when the mice were exposed to odors, the timing of glomeruli activity shifted significantly within the sniff cycle. 

Additional testing revealed that the phases altered the same amount no matter what the concentration level of the odor. This discovery establishes that odor and airflow neural stimulation can be distinguished by looking at the phase of activity in the glomeruli.

"Phase-coding is not unique to the olfactory system,” said Imai. "Although it has also been found in the hippocampus in relation to memory formation, we still do not know much about it. Hopefully, our finding will facilitate a better understanding of how neurons communicate with each other and how meaning can be derived from their signals."

"Our next step is to understand how the precise temporal patterns are generated in the olfactory bulb, and why they are affected by odors but not mechanically originating signals."

The research is published in the journal <a href="http://www.cell.com/neuron/home">Neuron</a>.

How the brain tells the difference between breathing and sniffing

Researchers at the RIKEN Center for Developmental Biology (CDB) set...

Experts from the UK and the United States are outlining the best investments in clean energy based on their analysis of recent research and innovation. The authors of the paper recommend that governments give technical experts more control of <a href="https://www.earth.com/news/green-solar-panels-appealing/">clean energy</a> programs in order to achieve more long-term stability.

The researchers have drafted six "guiding principles,” and are encouraging the support of programs that have staying power rather than just “ quick win” potential. Among the principles proposed by the research team are to adopt an adaptive learning strategy and to keep clean energy research funding predictable and stable.

"As the window of opportunity to avert dangerous climate change narrows, we urgently need to take stock of policy initiatives around the world that aim to accelerate new energy technologies and stem greenhouse gas emissions," says Laura Diaz Anadon, Professor of Climate Change Policy at the <a href="https://www.cam.ac.uk/">University of Cambridge</a>.

The authors are urging policymakers to learn what works from experience and build on it before time runs out. The experts say that some government officials are constantly reinventing clean energy goals and targets for the sake of political vanity.

"If we don't build on the lessons from previous policy successes and failures to understand what works and why, we risk wasting time and money in a way that we simply can't afford," says Anadon.

Public investments in energy research have steadily risen in recent years. For example, funding for new energy research and development by the Organization for Economic Cooperation and Development (OECD) jumped to $16.6 billion in 2016 compared to $10 billion in 2010. In addition, the EU and other nations pledged to double clean energy investment as part of Paris Climate Change Agreement.

Regardless, the study authors point out that government funding for energy innovation has become highly volatile in the recent past. Political shifts in the UK and the U.S. have resulted in huge budget fluctuations and process reinventions.

The research team found, for example, that one in five technology areas funded by the U.S. Department of Energy experienced a budget shift of more than 30 percent up or down every single year from 1990 to 2017. In 2018, the Trump administration plans to cut the energy research and development budget by 35 percent across the board.

In the UK, every Prime Minister since 2000 has created new institutions to manage energy innovation. 

"Experimentation has benefits, but also costs," explains Anadon. "Researchers are having to relearn new processes, people and programs with every political transition - wasting time and effort for scientists, companies and policymakers."

"Rather than repeated overhauls, existing programs should be continuously evaluated and updated. New programs should only be set up if they fill needs not currently met."

The research is published in the journal <a href="https://www.nature.com/nature/">Nature</a>.

Scientists are warning that <a href="https://www.earth.com/news/heavy-air-pollution-nuclear/">air pollution</a> in London is negatively impacting the health of unborn infants. The experts have determined that exposure to pollution generated by vehicles is associated with an increased risk of low birth weight babies born at full term.

While previous research has linked air pollution with complications in pregnancy, similar studies investigating the potential effects of noise pollution have been inconclusive.  

Researchers led by the <a href="https://www.imperial.ac.uk/">Imperial College London</a> set out to examine the outcomes of exposure to air pollution and noise pollution from road traffic during pregnancy. They focused their study on two potential birth weights, low birth weight and being born small for gestational age.

The research team used national birth registers to identify over 540,000 full-term births in the London area between 2006 and 2010. The experts estimated the average monthly concentrations of traffic-related air pollution at the home addresses of the mothers. They also estimated the average levels of noise pollution during daytime and nighttime hours.

Next, the researchers used statistical models to analyze the data. The study revealed that air pollutants from road traffic, particularly PM2.5, were associated with a 2 to 6 percent increase in the risk of low birth weight and a 1 to 3 percent increase in the risk of being small for gestational age.

There was no significant link found between noise pollution and complications at birth, yet the researchers reported that they "cannot rule out that an association might be observed in a study area with a wider range of noise exposures."

"Our findings suggest that air pollution from road traffic in London is adversely affecting fetal growth," said the study authors. They emphasized that reducing London's annual average PM2.5 concentration by 10 percent would prevent an estimated 90 babies being born with low birth weight at full term each year in London.

"With the annual number of births projected to continue increasing in London, the absolute health burden will increase at the population level, unless air quality in London improves," said the researchers. 

While the authors said that the findings of the study "should increase awareness that prenatal exposure to small particle air pollution is detrimental to the unborn child," they also stressed the fact that increasing awareness without solutions for risk reduction "may serve only to increase maternal anxiety and guilt."

The research, which is published by <a href="http://www.bmj.com/">The BMJ</a>, is applicable to other UK and European cities as well. The experts are urging for environmental health policies to improve air quality in urban areas.

We often take for granted our ability to take in sound and process the information into a cohesive meaning. It’s a complicated process that involves innumerable factors, not to mention the need to discern what you hear from distracting background noise. Now, researchers at <a href="http://www.auburn.edu/">Auburn University</a> have discovered that in demanding environments, both adults and children depend more on their right ear for processing and retaining what they hear.

Sounds that enter the right ear are processed by the left side of the <a href="https://www.earth.com/news/brain-processes-internal-experiences/">brain</a>, which controls speech, language development, and parts of memory. Together, each ear takes in separate bits of information, which are then combined while being processed through the auditory system. However, past research has shown the young children’s auditory systems are unable to sort and separate simultaneous information from both ears. Because of this, children rely mostly on their right ear to capture sounds and language, as the pathway is more efficient. But what is less understood is if this right-ear dominance is still present in adulthood.

To answer this question, Danielle Sacchinelli and her colleagues had 41 participants (ages 19-28) go through both dichotic separation and integration listening tasks. Dichotic listening tests are used to diagnose auditory processing disorders that cause the brain to have difficulty processing what is heard. This test involves listeners receiving different auditory inputs that are delivered to each ear simultaneously. Participants are asked to pay attention to sounds delivered to one ear, while dismissing sounds delivered to the other (separation) or are required to repeat all words heard (integration). 

As the tests progressed, the researchers increased the number of sounds until they passed the point of an individual’s simple memory capacity. Once they were beyond the participant’s memory span, they found that an individual’s performance improved by roughly 8 percent – and in some cases up to 40 percent – when they focused on their right ear.

“Conventional research shows that right-ear advantage diminishes around age 13, but our results indicate this is related to the demand of the task. Traditional tests include four-to-six pieces of information,” says Aurora Weaver, an assistant professor at <a href="http://www.auburn.edu/">Auburn University</a> and member of the research team. “As we age, we have better control of our attention for processing information as a result of maturation and our experience.”

Enhancing our understanding of how we listen and process information in demanding environments may help improve diagnostic tools, auditory management – such as hearing aids – and auditory training. Weaver also believes that this may increase our ability to deal with the decline of cognitive abilities as people age.

The chronic sleep deprivation that many youth and <a href="https://www.earth.com/news/screen-time-suicide-teens/">teens</a> face today has been well documented, with many health professionals calling for later start times in middle and high school, but these suggestions have gone largely unheard.

Adolescents need more sleep than adults, and chronic sleep deprivation in teens can actually raise their risk of depression and addiction, according to a new study. 

The study was conducted by researchers from the <a href="http://www.pitt.edu/">University of Pittsburgh</a> and documented the negative impact that sleep deprivation has on the brain’s reward system and mood. 

For the study, the researchers had 35 participants, ages 11 through 15, take part in a sleep lab study. 

For two nights, half the group slept for ten hours and the other half was only allowed to sleep for four fours. A week later, the participants came back to the lab but slept for the opposite amount of time they had for the first two nights. 

The study volunteers were also asked to play a game with monetary gains of one and ten dollars that activated the reward centers of the brain. The participants were given brain scans both weeks while they played the game. 

The researchers also had each participant answer questions about emotional functioning and if they experienced symptoms of depression. 

The results show that sleep deprivation impacted the putamen, a part of the brain involved with reward learning and goal-based movements. Even when the rewards in the game were higher during the sleep lab studies, the putamen was less responsive in the sleep-deprived subjects. 

The sleep-deprived participants also reported more symptoms of depression. These results correlate with research on how depression lowers activity in the brain’s reward system. 

Chronic sleep deprivation poses major health risks for all ages, but these results show that sleep deprivation in teens especially increases the risk of depression and addiction.

Science has proven that it’s crucial for <a href="https://www.earth.com/news/reaction-time-predict-mortality/">seniors</a> to stay active as they get older. But what happens when the environment you’re exercising in is toxic enough to counter those health benefits? In cities with heavy air pollution, this may very well be the case.

A new study conducted by scientists from <a href="https://www.imperial.ac.uk/">Imperial College London</a> and<a href="https://www.duke.edu/"> Duke University</a> found that adults over 60 lost all benefits of walking for two hours when subjected to short-term exposure to traffic exhaust and street pollution.

The study was published in the journal The Lancet and is the first study of its kind to look at exposure to pollution canceling out the benefit of exercise on both healthy patients and those with cardiorespiratory illnesses like coronary heart disease.

The research found that that exposure to busy city streets and traffic pollution countered the the positive effects of moderate exercise like walking, but that walking in parks significantly improved health and wellbeing.

“Combined with evidence from other recent studies, our findings underscore that we can't really tolerate the levels of air pollution that we currently find on our busy streets," said Fan Chung, Professor of Respiratory Medicine and Head of Experimental Studies in Medicine at the<a href="https://www.imperial.ac.uk/nhli"> National Heart &amp; Lung Institute at Imperial College</a>. “We call for greater access to urban green spaces for people to exercise.”

For the study, the researchers asked 119 volunteers over 60 years old who were either healthy or had a preexisting cardiorespiratory condition to walk for two hours during the day.

The participants either walked in Hyde Park in London or a busy section of Oxford Street. Pollution levels in Oxford Street often exceed air quality limits set by the <a href="http://www.who.int/">World Health Organization</a>.

The researchers took physical measurements before and after the walks so they could see how the exercise impacted the participants’ blood pressure, lung capacity, and arterial stiffness.

The study volunteers who walked in Hyde Park showed significant improvement in lung capacity within the first hour and the effects lasted even after the walk was completed. 

Walking along Oxford Street had a small impact on lung capacity, but it didn’t match nearly those that were in Hyde Park.

Healthy participants experienced a 24 percent reduction in arterial stiffness, and patients with preexisting conditions saw a 19 percent reduction when walking in Hyde Park. Those who walked on Oxford Street experienced much smaller reductions in arterial stiffness. 

Even when accounting for the stress-inducing environment of crowded Oxford Street, and the medications that some of the participants took, the results show the lasting positive effects that walking in non-polluted areas has on respiratory health. 

The study also highlights the importance of urban green spaces and reducing pollution in major cities.

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."

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



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



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



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.

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;
