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. Kate Sweeny, a psychology scientist at UC Riverside, suggests that patience might be less about our moral standing and more about how we handle the everyday irritations that life throws at us.

A team of researchers from the <a href="http://lyon-university.org/">University of Lyon</a> in France set out to determine how dogs respond to human speech. The experts are reporting that puppies love when people direct a type of “baby talk" at them and may even begin understanding some human words through these types of interaction, while older dogs appear to be indifferent.

To examine how <a href="https://www.earth.com/news/dogs-chocolate-poisoning-christmas/">dogs</a> react to the way that humans speak, the experts first recorded the voices of 30 women as they looked at photographs of dogs and spoke to the images. The women were exposed to pictures of both puppies and older dogs, and were also directed to repeat the passage to a person.

The script read, “Hi! Hello cutie! Who’s a good boy? Come here! Good boy! Yes! Come here sweetie pie! What a good boy!” 

The scientists compared the women's speech when it was directed at humans to when it was directed at dogs. It came as no surprise that the women had spoken in distinctive, high-pitched, musical tones to the animals,  but not to the humans. The women spoke at an even higher pitch when looking at puppy photos.

The researchers played the voice recordings  for 10 puppies and 10 adult dogs at a New York City animal shelter and filmed their responses. 

The documentation revealed that nine of the puppies reacted strongly to the voices, barking and approaching the loudspeaker even when the recording had been made for an older dog. Some of the puppies bent down toward the sound of the voices in a play bow, which is a pose that shows a puppy is in a playful mood.

Study lead author Nicolas Mathevon explained that the younger dogs most likely consider dog-directed speech as “an invitation to play.” The puppies were not nearly as excited by the recordings of the women speaking to other humans, however. 

As far as the adult dogs observed for the analysis, it made no difference if they were hearing speech which was directed at puppies, older dogs, or humans. “They had a quick look at the speaker, and then ignored it,” said Mathevon.

Further investigation is needed to determine if the dog-directed speech means something to the puppies that is not yet understand or whether it helps them to learn human words.

The study is published in the <a href="http://rspb.royalsocietypublishing.org/">Proceedings of the Royal Society B</a>.

A study from <a href="http://www.hbs.edu/">Harvard Business School</a> has revealed that people often switch lines when they are last, but this actually makes the waiting time longer. 

A basic <a href="https://www.earth.com/news/humans-judge-group-people/">human</a> need to feel like we are not in last place, also known as “last place aversion,” causes us to be twice as likely to move to a new line when we are standing in the very back.

The experts determined that people at the back of the line are 20 percent less satisfied than the others in the line. According to the analysis, one in five people choose to switch lines when they are last, leading to a considerably longer wait.

The study demonstrated that people who changed lines once waited about 10 percent longer than they would have waited if they had stayed in place, while people who changed lines twice had to wait about 67 percent longer

Speaking to <a href="https://www.theguardian.com/uk">The Guardian</a>, lead researcher Ryan Buell said, “It's nuts because the number of people behind you has nothing to do with how long you are going to wait, but it shapes our behavior.”


The study also showed that people who are last in a line are four times more likely to give up and just walk away.


Dr. Buell said that the first ten seconds are the most difficult for people to tolerate at the back of the line. He recommended striking up a conversation with another person while waiting, which may keep you more satisfied and help to prevent you from wasting valuable time.

<a href="http://www.nmu.edu/">Northern Michigan University</a> has introduced “medical plant chemistry" as a new major. The program, which is focused on marijuana, was developed in response to an enormous demand for trained analytical chemists in the marijuana industry.

Brandon Canfield is an associate professor of Chemistry at the college. 

“This area is just exploding. I mean, you see Washington, Colorado, Oregon, California with full legal recreational marijuana,” Professor Canfield told <a href="http://detroit.cbslocal.com/">CBS Detroit</a>. “You’ve got over half the states with medicinal legal, and with all of that has come a huge need for these trained analytical chemists.”

The legal marijuana industry currently employs as many as 230,000 Americans, and that number is expected to grow. Professor Canfield pointed out that there is no other undergraduate program like this in the country.

“I predict that the graduates from our program are going to have among the highest immediate job placement of any of our programs,” he said. “People are either going to go out and get jobs or they might go out and start their own business in the industry.”

A total of 12 students were enrolled in the program for its first semester, and Professor Canfield said that number will likely double or triple by next year. 

“The need for this is so great. You go to some of these cannabis industry conferences and everyone is talking about how they need labs, they need labs,” he said. “Or the bigger operations are trying to set up their own labs in house and they need trained analysts. And the skill set required to perform these analysis is perfectly matched with an undergraduate level education.”

The curriculum includes classes such as chemistry, plant biology, and business entrepreneurship. The students will not be working directly with <a href="https://www.earth.com/news/medical-marijuana-safe-kids/">marijuana</a> plants - at least not yet.

“We’re not going to be actually growing anything on campus,” explained Canfield. “Maybe following the 2018 Michigan election, maybe we’ll revisit that depending on the outcome and what ballots are present on that election. But for now, we’re not going to be growing any cannabis. We’ll be practicing extraction and analysis techniques on other plant systems.”

As of September 30, 2016, there were 218,556 patients in Michigan with medical marijuana cards. A committee called The Coalition to Regulate Marijuana Like Alcohol has collected over 350,000 signatures in an effort to let voters have the option of legalizing recreational marijuana on Michigan's 2018 ballot.

Since 2013, there have been hundreds of earthquakes in Oklahoma recorded at a 3.0 magnitude or higher. 

But now, those numbers are decreasing, largely because the <a href="https://earthquake.usgs.gov/research/induced/myths.php">United States Geological Survey </a>(USGS) identified what was inducing the earthquakes in the first place. 

It was thought that fracking might be the cause, but the USGS identified that wastewater disposal was the catalyst for the increase in seismic activity in Oklahoma.

The researchers report that one to two percent of all earthquakes in Oklahoma are caused by fracking, while the rest are induced by wastewater disposal. 

Wastewater disposal is the process when wastewater, typically produced through oil and gas extraction, is injected into wells deep into the Earth in porous sandstone or limestone.

“Wastewater disposal wells typically operate for longer durations and inject much more fluid than hydraulic fracturing, making them more likely to induce earthquakes,” the <a href="https://earthquake.usgs.gov/research/induced/myths.php">USGS</a> explained.

Once the real cause of the earthquakes in Oklahoma was identified, policy was put in place to regulate injection wells across the state, and thankfully, their efforts have been successful. 

2016 and 2017 saw a decline in seismic activity, differing from the increasing trend of past years. In 2016 there were 624 total earthquakes, and in 2017 that number dropped to 294. 

However, even with regulatory measures in place, the USGS warns that Oklahoma is still in danger of experiencing more seismic activity than is typical for the state. 

“The 2017 forecasted seismic rates are lower in regions of induced activity due to lower rates of earthquakes in 2016 compared to 2015, which may be related to decreased wastewater injection, caused by regulatory actions or by a decrease in unconventional oil and gas production,” the agency says. “Nevertheless, the 2017 forecasted hazard is still significantly elevated in Oklahoma compared to the hazard calculated from seismicity before 2009.”

Life expectancy at birth has <a href="https://www.earth.com/news/life-expectancy-overdose-us/">dropped</a> for two consecutive years in the United States, and experts say that this trend is on track to continue for a third year. Meanwhile, the life expectancies for most industrialized nations is headed in the other direction. 

The average global life expectancy is projected to substantially increase by 2030, which is due in large part to improvements in the health of adults and children alike. The following countries are the top 10 regions of the world paving the way for healthier, longer lives.

&nbsp;

Hong Kong

Thanks to advanced medical treatment in beating diseases like cancer, Hong Kong has the longest average life expectancy in the world at 84.28 years. In addition, only ten percent of the population of this country are smokers, and researchers say that the effects of anti smoking policies which were launched 30 years ago can now be witnessed in Hong Kong.

&nbsp;

Japan 

Japan has one of the lowest mortality rates in the world, and experts say this is primarily due to a diet that is low in saturated fats and processed foods. Diets high in certain carbohydrates, vegetables, fruits, and fish contribute to the longevity of the Japanese, who live to be an average of 83.7 years.

&nbsp;

Italy 

The incredible Italian life expectancy of 83.5 years is something of a mystery. Experts think that it may be hereditary and may also be a combination of factors such as low stress, high activity levels, and  healthy diets that include fresh fish and locally grown fruit and vegetables.

&nbsp;

Spain

Some people say that the secret to living longer is to live in Spain. Their Mediterranean diet, which reduces the risk of heart attack and stroke by 30 percent, along with lower suicide rates and improved healthcare helps the residents of Spain live to around 83.38 years.

&nbsp;

Switzerland

Life expectancy from birth has nearly doubled in Switzerland since the beginning of the 20th century. The numbers jumped from 49 to 85 for women and from 46 to 81 for men. The average life span is now 83.2 years, and many experts attribute this to the fact that the Swiss have wealth and a better sense of overall well-being.

&nbsp;

Iceland

Icelanders can expect to live an average of 82.9 years. Some researchers believe that this is due to genetics, while others argue that the Swiss simply live clean lives that allow them to have good health into their older years.

&nbsp;

France

Even though the life expectancy of the French took a considerable drop in 2015 due to a flu epidemic and the loss of over 600,000 lives, the country still holds a place on the list of countries which thrive the most - with an average life expectancy of 82.7 years.

&nbsp;

Sweden 

Sweden may have a place on this list simply due to the fact that people here have higher levels of overall well-being. Factors such as environmental quality, education and skills, work-life balance, health status, income and wealth, personal safety, and social connections enable Swedes to live approximately 82.6 years.

&nbsp;

Singapore

Good quality healthcare that is reasonably accessible may promote longer lives in Singapore, which has a life expectancy of 82.6 years. In particular, outstanding child and maternal health services and childhood disease prevention programs have helped to extend the lives of residents in this country.

&nbsp;

Australia 

With a sharp decline in smoking and a universal health care program that ranks among the best in the world, Australia is holding strong in regards to longevity, as Aussies can expect to live an average of 82.5 years.

Life expectancy at birth has dropped for two consecutive years...

Researchers at <a href="http://www.uwo.ca/">Western University</a> in Canada are reporting that short-term <a href="https://www.earth.com/news/hour-exercise-prevent-depression/">exercise</a> works wonders for the brain. The experts have found that even 10 minutes of aerobic activity can boost regions of the brain that help us focus and solve problems.

Previous studies have demonstrated brain-health benefits after 20 minutes of exercise. Researchers have also shown that commiting to an exercise program of 24 weeks or more is beneficial to the brain.

"Some people can't commit to a long-term exercise regime because of time or physical capacity," said study co-author Matthew Heath. “This shows that people can cycle or walk briskly for a short duration, even once, and find immediate benefits.”

Participants in the study were divided into two groups. They were directed to either sit and read a magazine or to perform 10 minutes of moderate-to-vigorous exercise on a stationary bicycle. 

Next, the researchers used eye-tracking equipment to examine how fast the individuals could react to an eye movement task. The activity was designed to challenge the regions of the brain responsible for executive functions such as decision-making.

“Those who had exercised showed immediate improvement,” said Heath. “Their responses were more accurate and their reaction times were up to 50 milliseconds shorter than their pre-exercise values. That may seem minuscule but it represented a 14-percent gain in cognitive performance in some instances.”

The work may be used to develop strategies for older people who are in early stages of dementia and are less mobile. The findings of the study also have significance for anyone looking to gain quick a mental edge.

"I always tell my students before they write a test or an exam or go into an interview - or do anything that is cognitively demanding - they should get some exercise first," said Heath. "Our study shows the brain's networks like it. They perform better.”

Heath is now conducting a study to determine how long the benefits last after a burst of exercise. The research is published in the journal <a href="https://www.journals.elsevier.com/neuropsychologia">Neuropsychologia</a>.

As another year ends and a new one begins, many people resolve to eat better, exercise more, and <a href="https://www.earth.com/news/losing-weight-saves-money/">lose weight</a>. A Nielsen survey found that about a third of Americans pledged to slim down and tone up as we rang in 2017, but Professor Pamela Keel of <a href="https://www.fsu.edu/">Florida State University</a> says a better resolution is to simply lose the critical thoughts about your body.

Keel’s research team is testing a new program encouraging body acceptance, and they are seeing dramatic results. 

“Consider what is really going to make you happier and healthier in 2018: losing 10 pounds or losing harmful attitudes about your body?” said Keel.

Keel has dedicated her entire career to studying body-image issues and how they relate to eating disorders. These problems are commonplace in America, particularly among young women.

An ideal body type has emerged over the past 35 years that is essentially unattainable for most people. Keel pointed out that the majority of Americans are overweight, which means there is a huge discrepancy between reality and the body types shown in the media.

“There's a big gap between what we're shown as being ideal and what to aspire to and where we actually are as a population,” said Keel. “That leaves people feeling bad about themselves, and, unfortunately, feeling bad about your body does not actually motivate a person to pursue healthy behavior.”

An intervention program called "The Body Project" was developed by Eric Stice of the <a href="http://www.ori.org/">Oregon Research Institute</a> and Professor Carolyn Becker of <a href="https://new.trinity.edu/">Trinity University</a>. Using ideas from this project, Keel has documented strategies to help people feel better about themselves. 

An exercise called mirror-exposure directs a person to stand in front of a full-length mirror in little clothing and identify specific body traits that are good. The praise can be focused on the body's outward appearance or the body's function.

“You would say, 'I really appreciate the way my legs take me wherever I need to go,’" said Keel. “‘Every day without fail, they get me out of bed, to the car, up the stairs and into the office. I don't have to worry about walking.' It can be that kind of functional appreciation of what your body does for you.”

The individual may choose instead to appreciate the appearance of a body feature like the skin or the shape of the shoulders.

“You can even go for higher risk body parts," said Keel. “Rather than looking at yourself and saying, 'I hate my gut,' you could say, 'I really like the shape of my legs.' If there is something about you that you like, the idea is to spend time focusing on it.”

Keel found that focusing on positive things helped transform people's feelings about their bodies.

"It turns out that discarding those unattainable body ideals also improves your mood, self-esteem, reduces disordered eating behaviors and may reduce the risk of self-injurious behavior," said Keel. "All sorts of things get better as a result of feeling better about your body."

Attainment of a healthy body image was also found to lead to healthier eating patterns. These results have been replicated among diverse groups of participants, including a national sorority system and men at risk for eating disorders.

"When people feel good about their bodies, they are more likely to take better care of themselves rather than treating their bodies like an enemy, or even worse, an object," said Keel. "That's a powerful reason to rethink the kind of New Year's resolutions we make for 2018."

<a href="https://www.earth.com/news/air-pollution-birth-defects/">Air pollution</a> is detrimental to health and wellbeing and has been linked to cardiovascular disease, reduced respiratory health, and even death. 

According to the <a href="http://www.lung.org/our-initiatives/healthy-air/sota/key-findings/">2017 “State of the Air Report”</a> released by the <a href="http://www.lung.org/">American Lung Association, </a>almost 4 in 10 people in the United States live in areas with risky levels air pollution. 

Now, a new study has found that even short-term exposure to air pollution levels below current quality standards increases the risk of death in older adults. 

The study was conducted by researchers from the <a href="https://www.hsph.harvard.edu/">Harvard T.H. Chan School of Public Health</a>, Boston. 

The researchers analyzed data from Medicare patients between the years 2000 and 2012 from almost 40,000 zip codes across the United States. 

The team examined pollution levels including particulate matter and ozone levels and compared these to death rates among the Medicare data used for the study. 

The results show that daily growth in pollution levels increases the risk of death for more than 22 million Medicare patients. Even if the levels calculated by the research team were below legal limits, exposure to pollution still correlated with a risk of death. 

This means that air pollution levels may need to be re-evaluated and that people with Medicare living in areas with ozone and particle pollution below current standards are still at risk of health problems and now, as the study shows, even death.

As it stands now, the <a href="https://www.epa.gov/laws-regulations/summary-clean-air-act">Clean Air Act</a> mandates that air quality standards for pollution be reviewed every five years, but with increasing levels of greenhouse gas emissions, pollutants are becoming more and more harmful. 

The researchers say that in order to revise the acceptable levels of pollution, further studies will need to be done specifically examining the risk of death at differing levels of air pollution.

As some environmental ideas become mainstream, such as ‘sustainability’ and the practice of recycling, companies are scrambling to catch up.  It’s important to know how to separate the wheat from the chaff, the truly green companies from those pretending to be <a href="https://www.earth.com/news/greenhouse-gas-emissions-100-companies/">environmentally friendly</a>.  

From my perspective, every company claiming to be environmentally friendly is in some way lying.  One case of this fakeness is Best Buy.  I worked stocking shelves in Best Buy on an overnight shift for the holidays a couple years back.  Best Buy went out of its way to paint the image of an environmentally friendly tech company.  Best Buy will recycle your electronics and batteries for free.  Some Best Buy gift cards that year had environmental slogans.  Why isn’t Best Buy green?  Let me spell it out.  When I was young and still in college I felt solar, wind and other alternative energies could save the planet.  I travelled to Tasmania and got a big wake up call.  

I worked on a small subsistence farm in Tasmania for free room and board.  The farm was entirely vegetarian, there was no electricity and as much food as possible was grown on the farm, organically.  Peter, the man who ran the farm, was one of the first people to question my environmental presumptions.  When talking about a large pulp mill being built in Tasmania, Peter said, ‘It’s the fault of people who use electricity.  You buy a light bulb that was shipped to a store in a cardboard box and packaged in paper, you’re contributing to pulp mills.’  

The point wasn’t that electricity use was the worst thing you could do, obviously reading books also contributes to pulp mills.  The point is that the more resources, any resources you consume, the larger your impact on the environment.  Peter, in his comment, also highlights the interconnectedness of our actions in society and the environment around us.  By writing this article on my laptop, using electricity and publishing it on a website to be read by other people using electricity, I’m making a compromise.  I’m knowingly making a trade-off between consumption (electricity, metals, plastics, etc. in my laptop) and informing the public (that’s you, reader).  

Even with solar panels producing electricity that is clean, few people think of the initial environmental impact of producing solar panels.  Recycling everything from plastic bottles to electronics isn’t without its problems either.  Recycling takes a lot of energy input.  Besides the carbon produced from recycling, it can contribute to child labor borne from the desperation of poverty with unsafe conditions.

The best practice when it comes to deciding whether an action, a purchase or life style is ‘green’ is to do as little as possible.  What I mean is, don’t buy something to support ‘green’ industry.  The less you buy, the greener it is; live simply.  When you do buy, buy used.  Buying used contributes less energy towards production of goods.  Second hand stores are often a better deal as well and sometimes profits go towards non-profit causes.  

Besides simplicity, we should always think deeply and look at unintended consequences.  For instance, I don’t eat meat.  It’s true that meat eating contributes more of a carbon footprint than vegetarian eating.  It’s also true that meat production demands more land and contributes to predator ‘control’ on wild animals.  There are many other environmental reasons for being vegetarian but it’s just an example.  Don’t assume an electric car is greener.  Think about where the electricity for that car is coming from; consider the environmental impact of producing and shipping an electric car.  If the electricity comes from solar or wind, think about the impact of installing windmills or solar panels.  An easy thing to do is walk instead of drive.  There’s no environmental downside to walking over driving and you might actually enjoy the environment you walk through more.

Remember that global climate change is only one of many environmental problems.  Plastic is quickly replacing fish in the ocean.  We’re on the edge of a massive global extinction, set to wipe out many plants, animals and fungi.  Getting out and connecting to our environment is more important than ever and yet federal public lands are under attack.  Kids spend more time inside and less outside connecting to the world around them and others.    

What’s green and what’s just green washing is a matter of opinion in the end.  The important thing is not to just believe a label or the hype around a certain product.  Being green is a personal responsibility, not something that can be passed off to business or government.  Trying your best and being imperfect is better than getting overwhelmed and giving up.  Inform yourself, think for yourself, trust yourself.

German scientists may have finally solved the mystery of what part of the brain recognizes human voices. The researchers are reporting that the area of the brain responsible for <a href="https://www.earth.com/news/politicians-voice-impacts-success/">voice</a> recognition is a small region known as the superior temporal gyrus (STG).

The STG is part of the right posterior temporal lobe, which is one of the four major lobes in the brain. Claudia Roswandowitz is a researcher at the <a href="https://www.mpg.de/149614/kognition_neuro">Max Planck Institute for Human Cognitive and Brain Sciences</a> and the lead author of the study.

Roswandowitz teamed up with other experts from the research group <a href="http://www.cbs.mpg.de/independent-research-groups/human-communication">Neural Mechanisms of Human Communication</a> for the investigation. The study was focused on 58 individuals with brain injuries in an effort to examine their ability to learn and recognize voices.

“Very valid statements about which brain areas are responsible for which functions are derived from investigations in patients with lesions,” explained Roswandowitz.

The <a href="http://www.cbs.mpg.de/voice-recognition-in-the-brain">study</a> revealed that patients with damage to the right posterior temporal lobe had trouble identifying the voices of other people, and individuals who had suffered from a stroke had even more difficulty.

Overall, 9 percent of the patients examined had difficulty in distinguishing one voice from another. The results of the study indicate that this particular region of the brain is critical in voice recognition. 

“These findings improve our understanding of how the brain identifies voices and provide the basis in the search for effective therapies for those affected by phonagnosia, a fairly common deficit which is sometimes present from birth but especially after a stroke,” said Roswandowitz.

“In our studies nine percent of the participants reported suffering from difficulties in recognizing voices, a problem that is almost unheard of in the medical sector.Thus, we have to raise awareness of this matter.”

A new <a href="https://qzprod.files.wordpress.com/2017/12/6043f-meyers-fallout-mortality-website.pdf">study</a> from <a href="http://www.arizona.edu/">University of Arizona</a> economist Keith Meyers reveals that radiation from nuclear tests during the Cold War led to many more deaths than previously thought. 

Between 1951 and 1963, the United States conducted over 100 above-ground nuclear tests at sites in Nevada. Meyers has found that as many as 690,000 casualties resulted after radioactive pollution made its way into the environment and the food supply.

Exposure to high levels of <a href="https://www.earth.com/news/air-travelers-fly-radiation-clouds/">radiation</a> can cause serious illness or death, and even low doses of radiation can cause cancer. The weapons developers were either unaware of these risks or just completely careless, and people working at test sites or living closeby were not the only ones in harm's way. Ultimately, millions of people were exposed to “tremendous" amounts of radiation.

“Counter-intuitively, the areas where fallout had the largest impact on the crude death rate was not in the region surrounding the test site, but rather in areas with moderate levels of radioactive fallout deposition in the interior of the country,” said Meyers.

Early attempts to calculate the extent of the fallout from nuclear tests were inaccurate because they did not account for the collateral damage that happened over time and space. 

“The largest health effects appear in areas far beyond the scope of previous scientific and medical studies,” explained Meyers. “The scientific and medical literature has studied the effects of atmospheric testing on populations residing in downwind counties in Arizona, Nevada, and Utah.”

After the nuclear tests, pollution was carried far away by winds. In addition, cows consumed irradiated grass which leaked radioactive material into the milk supply.

To analyze the number of deaths which resulted from nuclear testing, Myers used an empirical alternative approach which combined measures of radioactive fallout exposure from the <a href="https://www.cancer.gov/">National Cancer Institute</a> and mortality data from across the continental United States. 

Meyers found that radioactive fallout was to blame for between 340,000 and 690,000 deaths from 1951 to 1973, which is up to fourteen times more casualties than earlier research had demonstrated. 

Meyers explained that putting a stop to nuclear testing inadvertently saved millions of Americans from additional exposure. He estimated that the Partial Nuclear Test Ban Treaty was responsible for saving between 11.7 and 24 million lives.

“The evidence presented in this paper reveals that the health cost of domestic nuclear
testing is both larger and more expansive than previously thought,” said Meyers. 

“The mortality estimates may understate the magnitude of the true number of deaths attributable to nuclear testing and the magnitude of the health costs of this polluting defense policy. It is plausible that
these estimates are lower bounds of the true health effects.”

1950s nuclear tests exposed millions to radiation

A new study from University of Arizona economist Keith Meyers...

An odor can trigger memories and emotions from experiences long ago, and neuroscientists from the <a href="http://www.ruhr-uni-bochum.de/index_en.htm">Ruhr-Universität Bochum</a> set out to determine which region of the brain stores long-term memories of scents. They discovered that an area of the olfactory brain called the piriform cortex plays a role in saving memories, yet it does not operate alone.

“It is known that the piriform cortex is able to temporarily store olfactory memories," said study co-author Christina Strauch. “We wanted to know, if that applies to long-term memories as well.”

A biological process known as synaptic plasticity alters communication between neurons found in the brain. These synaptic changes contribute to memory and learning by storing new information on the brain's memory structures.

Through experimentation in mice, the researchers investigated if the piriform cortex is capable of expressing synaptic plasticity. They also wanted to examine whether synaptic changes lasted for more than four hours, which would indicate that long-term memory had been established.

The experts used electrical impulses in the <a href="https://www.earth.com/news/salad-vegetables-brain-young/">brain</a> with varying frequencies and intensities to emulate processes that trigger the encoding of an olfactory sensation as a memory. 

It is known that these procedures can produce lasting effects in the hippocampus, which is another region of the brain responsible for long term memories. Surprisingly, the protocols did not induce synaptic plasticity in the piriform cortex.

Next, the scientists set out to determine whether the piriform cortex needs to be instructed to create a long-term memory. To do so, they stimulated a brain area called the orbitofrontal cortex, which is responsible for the recognition of sensory experiences. This stimulation resulted in synaptic change in the piriform cortex. 

“Our study shows that the piriform cortex is indeed able to serve as an archive for long-term memories,” said Strauch. “But it needs instruction from the orbitofrontal cortex - a higher brain area - indicating that an event is to be stored as a long-term memory.”

The study is published in the journal <a href="https://academic.oup.com/cercor">Cerebral Cortex</a>.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

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



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

Today’s Video of the Day from the <a href="https://www.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;
