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 new study has found that the psychological consequences of the Industrial Revolution are lingering in many communities in the UK and the United States today. Even though this transitional period took place 200 years ago, former coal-mining and manufacturing communities are still contending with deep-rooted personality patterns distinguished by lower <a href="https://www.earth.com/news/notice-nature-boost-happiness/">happiness</a>, well-being, and health.

An international team of psychologists analyzed personality data from 381,916 individuals in England and Wales and from 3,457,270 individuals in the United States. The study revealed that people living in former industrial hubs are more inclined to experience anxiety and depressive moods. These individuals were also found to be more impulsive and more likely to struggle with self-motivation.

Martin Obschonka is an associate professor at <a href="https://www.qut.edu.au/">Queensland University of Technology</a> (QUT) from the Australian Centre for Entrepreneurship Research.

"Our findings show that, generations after the white heat of Industrial Revolution and decades on from the decline of deep coal mining, the populations of areas where coal-based industries dominated in the 19th century retain a 'psychological adversity'," said Professor Obschonka.

The team evaluated individual test scores using the "Big Five" personality traits which include openness, conscientiousness, extraversion, agreeableness, and neuroticism. The researchers further classified the personalities by examining characteristics such as altruism, self-discipline, and anxiety.

"It is our belief that this generational unhappiness and dysfunction is the inherited product of selective migrations during mass industrialization compounded by the social effects of severe work and living conditions," said Professor Obschonka.

"This damaging cognitive legacy of coal is reinforced and amplified by the more obvious economic consequences of high unemployment and economic hardship we see today."

According to the experts, the two factors most likely driving the link between personality traits and historical industrialization are migration and learned behavior.

"The people migrating into industrial areas were often doing so to find employment in the hope of escaping poverty and distressing situations of rural depression - those experiencing high levels of 'psychological adversity'," said Professor Obschonka.

"However, people that left these areas, often later on, were likely those with higher degrees of optimism and psychological resilience. This selective influx and outflow may have concentrated so-called 'negative' personality traits in industrial areas - traits that can be passed down generations through combinations of experience and genetics."

The researchers pointed out that the findings of this study can be used to predict future economic and social conditions across these communities considering that regional personality patterns determine these trajectories. The analysis is published in the <a href="http://www.apa.org/pubs/journals/psp/">Journal of Personality and Social Psychology</a>.

While marijuana has has a reputation as a trigger of psychosis, a cannabis compound may help ease symptoms of the condition, a British study found.

The study, led by researchers from <a href="https://www.kcl.ac.uk/">King’s College London</a>, adds to a growing list of illnesses and symptoms that may be treated with cannabidiol. The cannabis compound known as CBD has also been shown to have therapeutic possibilities for multiple sclerosis, epilepsy, peripheral neuropathy, arthritis, chronic pain and other conditions.

“Although it is still unclear exactly how CBD works, it acts in a different way to anti-psychotic medication, and thus could represent a new class of treatment,” study lead author Dr. Philip McGuire told the <a href="http://www.dailymail.co.uk/">Daily Mail</a>. 

CBD does not rely on dopamine receptor antagonism, unlike current treatments for schizophrenia. 

The Kings College scientists worked with 88 study participants to look at how the cannabis compound affected psychosis symptoms like visual and audio hallucinations. During the six-week study, some of the patients received CBD while others got a placebo. All of the study participants continued to take their regular medication. 

Those who were treated with cannabidiol reported fewer psychotic symptoms than those who took the placebo. 

It’s not the first study to show CBD’s abilities to ease psychosis symptoms. A review of existing studies showing cannabidiol could have anti-psychotic properties was published in <a href="http://www.sciencedirect.com/science/article/pii/S0924977X13003325">European Neuropsychology</a> in 2014.

The drug may also offer fewer side effects than traditional anti-psychotic medications, the researchers said.

But with cannabis also linked to triggering psychosis, scientists are stressing caution. 

While cases of marijuana triggering psychosis are relatively rare, Dr. Ian Hamilton of <a href="http://www.yorku.ca/">York University</a> found in a different study, strains with high levels of tetrahydrocannabinol (THC) have been found to raise the risk of a psychotic episode. THC is the chemical that causes a high.

A previous study led by Dr. Sir Robin Murray, also of Kings College London, found that regular use of stronger strains of marijuana which contain more THC is associated with a higher risk of psychosis.

However, cannabidiol, which doesn’t cause a high, doesn’t appear to have the same negative effects, scientists said. 

The Kings College study has been published in <a href="https://ajp.psychiatryonline.org/doi/abs/10.1176/appi.ajp.2017.17030325">The American Journal of Psychiatry</a>.

10 of Earth’s most beautiful beaches

You cannot beat a trip to the beach for relaxation...

As we begin to wrap up the year, it goes without saying that 2017 included one of the worst <a href="https://www.earth.com/news/hurricane-harvey-global-warming/">hurricane seasons</a> of all time. Hurricane Harvey caused massive flooding in Houston Texas, and the Florida Keys and Caribbean were devastated by Hurricane Irma. Hurricane Maria also caused flooding, power outages, and downed buildings in Puerto Rico and the Caribbean. 

In all areas affected by the 2017 hurricane season, displaced animals are in desperate need of care and attention. 

The idea of leaving a pet behind during a hurricane may seem unthinkable. Many photos and video clips shared during all three hurricanes included people evacuating with kennels or <a href="http://www.cnn.com/2017/08/26/us/gallery/hurricane-harvey/index.html">holding their pets close</a>. 

But sadly, sometimes the realities of evacuation leave little time or consideration for pets and livestock, meaning that many animals were left behind. 

Now, with floodwaters receded and relief efforts underway, many organizations are coming together specifically to help those animals that were abandoned during Hurricane Maria. 

<a href="https://www.alltherooms.com/w/2017/11/caught-storm-helping-animals-hurricane-damaged-caribbean/">All the Rooms</a> is a company passionately committed to spreading the word about the many organizations helping displaced animals in the Caribbean. 

Rather than working with just one organization, <a href="https://www.alltherooms.com/">All the Rooms</a> has created a comprehensive rundown of all the relief efforts working to help animals affected by the hurricanes. 

For example, <a href="http://humanebroward.com/">humane societies</a> have been working hard to transport displaced pets and rehome them in the United States. A few organizations like<a href="https://www.peta.org/"> PETA</a> and the <a href="http://www.ifaw.org/">International Fund for Animal Welfare</a> provide food and veterinary care to animals in hard-hit areas in the Dominican REpublic. . 

Getting aid to disaster areas takes time, effort, and often relies on donations. Thankfully, <a href="https://www.alltherooms.com/w/2017/11/caught-storm-helping-animals-hurricane-damaged-caribbean/">All the Rooms</a> has simplified and expedited the process for those looking to help get much-needed aid to animals affected by the 2017 hurricane season. 

Check out the All The Room’s <a href="https://www.alltherooms.com/w/2017/11/caught-storm-helping-animals-hurricane-damaged-caribbean/">comprehensive list</a> if you want to learn more.

Bioluminescence is the chemical reaction that occurs in fireflies and a variety of marine organisms that causes them to glow in the dark. It is most commonly found in organisms living in ocean ecosystems, especially at lower depths. 

But soon, bioluminescent trees may illuminate city streets thanks to a recent breakthrough from researchers at the<a href="http://web.mit.edu/"> Massachusetts Institute of Technology</a>. 

New research resulted in watercress plants glowing almost bright enough to serve as a desk light for three and a half hours and is just the first step, according to the team of scientists.

To create bioluminescence in the watercress plants, the researchers injected nanoparticles composed of special enzymes that are necessary for producing the chemical reaction that causes the glowing effect. 

The enzymes, luciferase and Co-enzyme A, were put in different nanoparticle carriers and injected into a watercress plant. 

Luciferase, which acts on a molecule called luciferin, is the heart of all bioluminescence. 

After carefully treating the plant with nanoparticles, the watercress was successfully bioluminescent. Thought it was not quite bright enough to serve as a desk lamp, the researchers could read partial book passages with it. 

At first, the plant’s <a href="https://www.earth.com/video/glowing-aurora-north-america/">glow</a> time was around 45 minutes, but this was soon extended to almost four hours.

If the researchers continue their efforts, bioluminescent street lamps and indoor lighting may very soon be a reality and would be an eco-friendly and energy efficient alternative to electricity. 

“The light is ultimately powered by the energy metabolism of the plant itself,” said Michael Strano, the senior author of the study. “Our work very seriously opens up the doorway to streetlamps that are nothing but treated trees, and to indirect lighting around homes.”

According to new research, people have sharper memories when thinking about having a baby or raising their kids.

A new study conducted by researchers from <a href="https://www.binghamton.edu/">Bingham University, the State University of New York</a> found that our ability to memorize information is influenced by evolutionary patterns set in motion thousands of years ago. 

Because procreation was a means of survival for our ancient ancestors, it makes sense that when motivated by the idea of evolutionary success, certain <a href="https://www.earth.com/news/brain-recognize-familiar-faces/">brain</a> functions would perform at higher levels. 

“Our ability to think and memorize information arises from our nervous systems," said Ralph Miller, a member of the research team. “As our nervous systems are a product of evolution and past experiences, one can reasonably expect that how well we memorize information today is influenced by natural selection that occurred amongst our ancestors long ago.” 

For the study, researchers asked participants to rate words in regards to different hypothetical scenarios. Some of the scenarios dealt with survival, some with raising a child, and a few of the scenarios were unrelated to either.  

After rating the words in the scenarios, the researchers asked the participants to remember as many of the words as they could. 

The researchers found that words relating to survival scenarios were recalled more frequently than the words that did not. The subjects also remembered more words when the scenario involved raising children. 

According to the researchers this shows that genetics plays a strong role in our thought processes. 

“What is evident is that the specific functioning of our brains, like our height and hair color, is strongly influenced by genes that were selected for among our ancestors,” said Miller.

Inspiration can come from the most random of sources. For Howard Stone, a professor of mechanical and aerospace engineering at <a href="https://engineering.princeton.edu/">Princeton University</a>, the inspiration for his new research project on the layered structure of <a href="https://www.earth.com/news/coffee-nuts-heart-health/">coffee</a> came from an emailed picture of a layered coffee drink he received unsolicited. Small details can also have big implications, and Stone’s research that followed may help explain the heat- and salinity-dependent flows of Earth’s oceans.

Nan Xue, a graduate student and lead author of the paper, began investigating these coffee layers by preparing lattes in the lab using store-bought coffee and milk. After much trial and error, he found that he was only able to achieve the characteristic café latte layering by staying within certain parameters, such as temperatures and pour rates. This showed that there must be underlying, quantifiable physics that are involved in this liquid structure formation.

“The structure formation in a latte is surprising because it evolves from the chaotic, initial pouring and mixing of fluids into a very organized, distinct arrangement of layers,” says Nan Xue.

Using a panel of light-emitting diodes and a camera – as well as a coffee and milk substitute (dyed water for coffee and salty, denser water for milk) – the researchers captured the movement of fluids within the mixture. They also seeded the concoction with tracer particles, which scattered light from a green laser beam, allowing them to further track the drink’s internal dynamics. 

The results showed that that primary mechanism behind layering is a phenomenon called double-diffusive convection. This occurs when stacked-up fluids of different densities are made to mix their contents, and exchange heat through the movement of their constituent materials. Within a given mixture, lighter, hotter liquids rise, while cooler, denser liquids sink. When the local density in a region within the mixture approaches equilibrium, the sinking and rising stops. Thus, the fluid in that region flows horizontally, rather than vertically. This creates distinct bands, or layers.

Perfecting techniques for creating sought-after layers of liquids flowing into each other has implications that stretch beyond simply pouring coffee. Improving our understanding of the mechanics of this process could reduce costs and complexity in a wide range of applications.

“From a manufacturing perspective, a single pouring process is much simpler than the traditional sequential stacking of layers in a stratified product,” explains Stone. “In one application of this study, we are exploring the physics behind making a whole layered structure with one step, rather than one-by-one stacking of the layers.”

Detlef Lohse, a professor of fluid mechanics at the University of Twente in the Netherlands who was not involved in this study, believes that the results of this research are quite significant. “I think it will have bearing on various industrial flows and mixing procedures in so-called process technology, in which mixing of fluids with different densities by the injection of one into the other is omnipresent,” he explains.

Furthermore, Lohse points out that this study may help better explain the heat- and salinity-dependent flows of water in Earth’s oceans. This may have major implications in climatology and ecology. “The most awesome finding may be that there is perfect analogy between the layering in a cafe latte,” says Lohse, “and the known and extremely relevant layering of water with different temperatures and salt concentrations in the ocean.” 

Who knew? The physics and fluid mechanics of your morning cup of coffee could be deeply connected to the phenomena occurring in our vast oceans.

There are many people who swear that their sore or achy joints are a sure sign that rainy weather is on its way. But a new study from <a href="https://hms.harvard.edu/">Harvard Medical School</a> has found that the weather has no bearing on joint pain whatsoever. 

The research was published in the journal BMJ.

The researchers, led by Anupam Jena of <a href="https://www.hcp.med.harvard.edu/">Harvard Medical School's Department of Health Care Policy</a>, examined a wide-reaching collection of Medicare records to see if any connection could be found between joint pain and inclement weather. 

Data was gathered from more than 11 million primary care office visits between 2008 and 2012, and this information was grouped with daily rainfall totals from <a href="http://www.noaa.gov/">National Oceanic Atmospheric Administration</a> weather stations. 

Jena and the researchers looked for patterns in the data including an increase in clinic visits during rainy weather, and if patients seeking care for an unrelated issue asked for help with aching joints if it had rained during their appointment. 

After a thorough analysis, the researchers couldn’t find any link between joint pain and rainy weather.

“No matter how we looked at the data, we didn't see any correlation between rainfall and physician visits for joint pain or back pain,” said Jena. “The bottom line is: Painful joints and sore backs may very well be unreliable forecasters.” 

Jena notes that given how much data the researchers combed over, if there were any indication of joint pain related to weather, it would have been apparent in the numbers, but it wasn’t.

Even if it’s scientifically unfounded, the researchers say the reason people claim to experience more pain during bad weather is that humans are wired to look for patterns. If someone’s knee unexpectedly starts hurting during a rainy day, it’s easy to blame the weather. 

Jena proves that rain has no effect on joint pain, but also makes a point to say that for physician’s, treatment of pain should be the only priority. 

“Pain is pain, with or without rain,” Jena said. “But it's important to know that, at the clinical level, joint pain does not appear to ebb and flow with the weather.”

If you aren’t getting enough <a href="https://www.earth.com/news/sleep-deprivation-depression-teens/">sleep</a>, it can have a huge impact on your cognitive function, mood, behavior, and health and wellbeing. But interestingly enough, different people vary in how much sleep they need to be at their best. 

Now, a new study has found that genetic differences could explain why some people need much more sleep than others to function at peak levels. 

The research was performed by scientists from the <a href="https://www.nhlbi.nih.gov/">National Heart, Lung, and Blood Institute</a>, who used fruit flies that were bred to model the natural variations in human sleep patterns. 

The results show how genes related to sleep variation are also connected to many other biological processes. 

“The involvement of highly diverse biological processes in sleep duration may help explain why the purpose of sleep has been so elusive,” said Susan Harbison, the leader of the study. 

The study was published in the journal PLOS Genetics.

The researchers bred 13 generations of fruit flies, purposely creating flies that slept for 18 hours a day or 3 hours a day. 

“What is particularly interesting about this study is that we created long- and short-sleeping flies using the genetic material present in nature, as opposed to the engineered mutations or transgenic flies that many researchers in this field are using,” Harbison said. 

The researchers then analyzed genetic data from the fruit flies, comparing the long and short sleepers to see if there were any differences between the two. 

After comparing the data, the research team identified 126 differences within 80 genes that were directly associated with sleep duration. 

The differences were connected to developmental and cell signaling pathways, and some of the genes identified were vital to brain development, learning, and memory. 

The results also show that both groups of fruit flies had similar life spans, meaning that there weren’t any extra adverse effects with sleeping for shorter or longer periods.

This study shows why some people may need more or less sleep than others and could help with creating new treatments and therapies for sleep disorders.

Traffic jams in major cities can be brutal. In one extreme case in 2010, a 62-mile traffic jam in Beijing lasted a grueling <a href="https://www.forbes.com/sites/jimgorzelany/2013/05/21/the-worst-traffic-jams-in-history/#722bc923e1aa">12 whole days</a>. 

Too many cars, not enough road, construction, accidents, and inclement weather all contribute traffic congestion, leading to an uptick in road rage and angry driving.

However, a new study suggests that traffic jams could be solved with a simple change in how drivers and car sensors perceive the other cars around them. 

The study, conducted by researchers from the <a href="http://web.mit.edu/">Massachusetts Institute of Technology</a>, shows that traffic congestion can be solved if all drivers adhered to one new rule: no more tailgating or driving as close as you can to the person in front of you. 

The researchers found that keeping an equal distance between <a href="https://www.earth.com/news/electric-cars-dangerously-quiet/">cars</a>, both front and back, would drastically reduce congestion and speed up commutes. 

This method is called bilateral control and was first introduced by MIT professor Berthold Horn in 2013. In this most recent study, Horn examined not just the cars and drivers themselves, but entire highway systems and traffic patterns. 

For Horn, the answer is simple. Car manufacturers need to outfit cars with electronic sensors that monitor cruise control to keep equal distances to cars on the road. This would be far easier than trying to change the driver’s deeply ingrained habits. 

“We humans tend to view the world regarding what's ahead of us, both literally and conceptually, so it might seem counter-intuitive to look backwards,” said Horn. “But driving like this could have a dramatic effect in reducing travel time and fuel consumption without having to build more roads or make other changes to infrastructure.” 

Building cars with cruise control sensors in both the front and back of the car would easily make tailgating a thing of the past, even if only a small percent of all cars had such systems installed. 

Horn and his colleagues examined the patterns of starling birds as they move in tandem, or as it’s called a murmuration. Thousands of starlings can come together in a flock and their flight patterns are mesmerizing. 

These murmurations are only possible because each bird is connected, fully aware of the birds around it so that when one bird moves, everyone moves. 

Horn suggests outfitting cars with front and rear cruise control so that they are similarly connected to other cars on the road. 

“Birds have been doing this for centuries,” said Horn. “To program this behavior, you'd want to look at the birds all around you and not just the ones in front of you.” 

Horn, with funding from Toyota, plans to conduct future studies that include simulations to see if the bilateral control method is both safer and faster for drivers.

When you think about the greenest places on Earth, you might think of lush <a href="https://www.earth.com/news/forests-wildfires-climate-change/">forests</a> in northern California or Alaska. Vast stretches of forest cover both the east and west coasts, with particularly dense forests along the Great Lakes region.

The Eastern Deciduous Forest stretches from Florida to Canada, covers 26 states and spans ten different forest regions. On the west coast, there are similar vast stretches of forest that run from California to Canada.

The Earth is packed with dense greenery, but this isn’t readily apparent without a topographic map that highlights forest cover. 

But now, a geographer has turned U.S. topography into works of art with forest cover maps showcasing the rich, green forests spanning the country.

Robert Szucs is a geographer and Geographic Information System (GIS) analyst with a love of maps who was inspired to showcase his work and studies by transforming it into posters. Szucs sells his work on his <a href="https://www.etsy.com/shop/grasshoppergeography">Etsy page</a>.  

One of Szucs’ creations shows long stretches of forest cover both on the East and West coast, with dense forests along the Great Lakes region. Running down the middle of the states is a black blank slate where desert and plains make up most of the land.

Szucs also has maps of the intricate river basins in the US and maps from all over the world including Germany, Italy, Sweden (one of the greenest in the collection), and population density heat maps of Europe and the US. 

To create the forest cover maps and photographs, Szucs uses an open-source Geographic Information System (GIS). GIS is a computer system designed to show the spatial relations of objects and formations on the Earth’s surface. GIS can show multiple layers like road maps and forests on a single layer. 

Scuzs then uses specific editing software to manipulate the images to create a specific effect or highlight particular layers. His work shows how varied and vast the Earth’s topographic natural makeup is, with swaths of forest and desert and rich veiny river systems. 

The crossover between geography and art makes Szucs’ work accessible to a wide audience and beautifully displays the ingenuity of the artist.

<a href="https://www.earth.com/news/online-food-shopping-healthy/">Healthy eating</a> may have more benefits for kids than just improved physical health, according to a new study published in the journal BMC Public Health. According to researchers from the University of Gothenburg in Sweden, healthy eating is linked to kids having better self-esteem and fewer emotional and peer problems. Furthermore, the inverse is true as well, when individuals have higher self-esteem they also adhere more closely to healthy eating guidelines.

In this study, researchers examined 7,675 children from age two to nine years and across eight European countries. At the beginning of the study, parents were asked to report how often per week their children consumed food from a list of 43 items. Depending on which foods they ate, children were assigned an Healthy Dietary Adherence Score (HDAS), which aims to capture adherence to healthy dietary guidelines. These guidelines include limiting refined sugars, reducing fat intake, and eating fruits and vegetables.

A higher – and thus healthier – HDAS at the beginning of the study period was associated with better self-esteem and fewer emotional and peer problems two years down the road. They also found that associations between HDAS and wellbeing were similar for both children of normal weight and children who were overweight.

“It was somewhat surprising to find that the association between baseline diet and better well-being two years later was independent of children’s socioeconomic position and their body weight,” says Dr. Louise Arvidsson, the corresponding author of the study. Assessment of psychosocial well-being was based on self-esteem, parent relations, as well as emotional and peer problems reported by the parents in response to validated questionnaires. 

This study is the first to analyze the individual components included in the HDAS and their connection to children’s well-being. However, the authors do caution that children with poor diet and poor wellbeing were more likely to drop out of the study and as a result were underrepresented at the two-year follow-up. This factor may complicated any conclusions about the true rates of poor diet and poor wellbeing. Furthermore, no conclusions on cause and effect can be made, as the study was purely observation and relied on self-reported data from parents.

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



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



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

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



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



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

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



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



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



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

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



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

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

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



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



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



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



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

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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

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



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



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



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



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