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.

In the coming weeks, people will be consuming more alcohol while celebrating the holidays, but researchers have now identified an unexpected cause of heavier drinking year-round. The scientists have found that the growing size of wine glasses has contributed to rising levels of drinking, particularly over the past two decades.

Researchers at the <a href="https://www.cam.ac.uk/">University of Cambridge</a> have determined that the capacity of <a href="https://www.earth.com/news/chocolate-red-wine-wrinkles/">wine</a> glasses in England increased from an average of 66 milliliters in 1700 to 449 milliliters in 2017.

Alcohol consumption has increased sharply since the 1960s. By 1980, nearly four times as much wine was being consumed compared to 1960, and that number almost doubled again by 2004.

Larger plates have been linked to increased food consumption, but less is known about the association between glassware and alcohol consumption. The research team set out to investigate if the growing size of wine glasses contributed to the rapid growth of wine drinking over the last few decades. 

Using data gathered from antique glassware experts and internet searches, the researchers collected measurements for 411 wine glasses in England between 1700 to 2017. 

The results of the study showed that the capacity of wine glasses in England gradually increased over the past 300 years, with a notable increase after the 1990s. At the beginning of this century, the average wine glass was 417 millimeters, and it jumped to 449 millimeters by 2016.

The researchers identified many potential explanations for the increase in glass size since 1990. They explained that a demand for larger wine glasses by the U.S. market was met by an increase in the size of glasses manufactured in England. The team also found that the glass sizes were influenced by bar and restaurant owners attempting to increase wine sales.


The experts ultimately concluded that lower prices, increased availability, marketing, and larger wine glasses all played a role in higher levels of wine consumption.

The study is published in the Christmas issue of <a href="http://www.bmj.com/">The BMJ</a>.

A new study links higher levels of <a href="https://www.earth.com/news/air-pollution-birth-defects/">air pollution</a> to bad behavior in teenagers. Researchers say that this serves as a reminder of the importance of clean air and the need for more plants and trees in urban areas.

Diana Younan from the <a href="https://keck.usc.edu/">Keck School of Medicine of USC</a> is the lead author of the study. She explains that fine particulate matter (PM2.5) can be extremely harmful to health.

"These tiny, toxic particles creep into your body, affecting your lungs and your heart," said Younan. "Studies are beginning to show exposure to various air pollutants also causes inflammation in the brain. PM2.5 is particularly harmful to developing brains because it can damage brain structure and neural networks and, as our study suggests, influence adolescent behaviors."

The study, which was focused on 682 children in Los Angeles, followed the subjects for nine years beginning when they were 9 years old. Parents reported every few years regarding if their child had engaged in various delinquent behaviors, including lying, cheating, truancy, stealing, vandalism, arson, or substance abuse. 
The research team used 25 air quality monitors to measure daily air pollution in Southern California from 2000 to 2014. Mathematical models enabled the team to calculate the ambient PM2.5 levels outside of the home of each participant. 

Overall, 75 percent of the individuals examined for the study breathed ambient air pollution that exceeded the federal recommended levels. Some areas had nearly double the levels of PM2.5 which are deemed safe.

The results of the study indicated that ambient air pollution increased delinquent behavior among the young adults. The negative effects were found to be worsened by poor parent-child relationships and also by mental stress among the parents.

"Previous studies by others have shown that early exposure to lead disrupts brain development and increases aggressive behavior and juvenile delinquency," explained Younan. "It's possible that growing up in places with unhealthy levels of small particles outdoors may have similar negative behavioral outcomes, though more research is needed to confirm this.”


The researchers determined that neighborhoods near freeways and those lacking in foliage experience higher levels of ambient air pollution. 

"Poor people, unfortunately, are more likely to live in urban areas in less than ideal neighborhoods," said Younan. "Many affordable housing developments are built near freeways. Living so close to freeways causes health problems such as asthma and, perhaps, alters teenagers' brain structures so that they are more likely to engage in delinquent behavior."

The study, which is published in the <a href="http://www.apa.org/pubs/journals/abn/">Journal of Abnormal Psychology</a>, also revealed that PM2.5 pollution and crime rates in Southern California have both been on the decline.

As hydraulic fracturing, or <a href="https://www.earth.com/news/links-fracking-drinking-water-pollution/">fracking</a>, becomes more widely used across the United States, concerns are growing about the potential health and environmental consequences that may follow. New research reveals that there are health risks for babies born to mothers living within 2 miles of a hydraulic fracturing site.

The researchers found that mothers living within half of a mile from a drilling site were 25 percent more likely to give birth to an infant born at a low birth weight. This condition leaves babies at a greater risk of infant mortality, ADHD, asthma, lower test scores, and lower lifetime earnings.

Study co-author Janet M. Currie is a professor of Economics and Public Affairs at the <a href="http://wws.princeton.edu/">Princeton University Woodrow Wilson School of Public and International Affairs</a>.

"Given the growing evidence that pollution affects babies in utero, it should not be surprising that fracking, which is a heavy industrial activity, has negative effects on infants," said Currie. 

The research team analyzed records from over 1.1 million births in Pennsylvania between 2004 and 2013. They compared the outcomes of babies born to mothers living near a hydraulic fracturing site to those living farther away, taking into account when fracking began at specific sites.

The study revealed that mothers living within .6 miles of a fracking site were 25 percent more likely to have babies born under 5.5 pounds, which is considered low birth weight. This risk decreased by about half to one-third for women who resided between half a mile and 2 miles from a drilling site, while infants born to mothers living beyond 2 miles from a fracking site showed little to no impacts.

"As local and state policymakers decide whether to allow hydraulic fracturing in their communities, it is crucial that they carefully examine the costs and benefits, including the potential impacts from pollution," said study co-author Michael Greenstone. "This study provides the strongest large-scale evidence of a link between the pollution that stems from hydraulic fracturing activities and our health, specifically the health of babies."

The research is published in the journal <a href="http://advances.sciencemag.org/">Science Advances</a>.

When tropical forests are converted to land for agricultural use, the result is less rain, more droughts, and deteriorating freshwater ecosystems. And now, surprising new research reveals that the clearing of tropical forests can also lead to negative changes in fish production.

Study lead author Leandro Castello is an assistant professor of Fisheries at <a href="https://vt.edu/">Virginia Tech</a>'s College of Natural Resources and Environment. The researchers set out to investigate how <a href="https://www.earth.com/news/mining-deforestation-amazon-rainforest/">deforestation</a> along the Amazon River impacts fish yields.

"The conflict between raising cattle and managing fisheries is a concern that is shared with floodplain residents, but there had been no rigorous studies of how loss of forest affects the productivity of floodplain fisheries," explained study co-author David McGrath.

Approximately one-third of the world's wild-caught fish yield comes from tropical regions, and fisheries are critical to this production. The conditions of the area of land adjacent to a river, known as a floodplain, have a major impact on the success of fisheries.

"Floodplain forests can provide structures that protect fish and their offspring, and provide habitat for insects that many fish rely on for food,” said Castello. “Those forests also produce plant material on which fish may also feed.”

Using a study area of 1,000 square kilometers, the researchers collected data on fisheries yields over a 12-year time period. The team also created a map of the region's 1,500 lakes and interviewed local fishermen about fish caught in different areas. By combining this data, the experts determined which areas yielded the most fish.

"We collected roughly 36,000 separate data points that were plotted in order to make a map of where the fish were coming from," said Castello.

Satellite images from NASA allowed the researchers to collect a second data set on habitat features in the study region to examine whether the presence of floodplain forests impacted fish yields.

"Essentially, we wanted to know if fish yields in areas with forested floodplains are greater, the same, or less than areas where forests have been cut down," explained Castello.

"Our results indicated that lakes with floodplain forests provided fishers with greater fish yields," he said. "This allows us to infer that if you cut down the forests, fish yields in those lakes would decrease. Tropical deforestation is not only a terrestrial issue - it can also decrease the number of fish available to some of the world's poorest populations."

The researchers will continue to investigate what other factors affect fisheries yields, but the indications of this particular study are clear.

"You have to protect these habitats if you want to maintain the food production and the income that rivers provide," said Castello. "If we don't protect these areas, we lose the rivers and we lose the fish."

The study is published online in the journal <a href="http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1467-2979">Fish and Fisheries</a>.

Pet owners often feel that their furry companions are like their children. According to a recent <a href="http://time.com/money/4876151/millenials-homes-dogs-children-marriages/">report</a>, one of the number one motivations for millennials looking to buy a house is so they will have space for their dog. 

<a href="https://www.earth.com/video/dogs-smarter-cats/">Dogs</a> are particularly sensitive to humans and with a loyal nature and seemingly perpetually wagging tail, it can be hard not to infantilize or anthropomorphize canine pets.

Now, new research has found that even though we love our pets like a member of the family, treating them like children can often lead to a misunderstanding of the dog’s natural behaviors and actions. 

It turns out that dogs are much more tuned in to our emotions and moods, but as owners, humans are not nearly as proficient at reciprocating and understanding our dogs. 

The research will be presented at the Royal Institution Christmas Lectures by Sophie Scott, a professor of cognitive neuroscience at <a href="https://www.ucl.ac.uk/">University College London</a>.

Scott’s findings show that dogs have much more emotional intelligence than we think, and our tendency to treat animals like children is detrimental to the animal’s sensibilities. 

According to Scott, we do not view dogs the same way they view us. Research has found that to them, humans have a similar role as an alpha animal would in a hypothetical pack in the wild. 

In an interview with the <a href="https://www.thetimes.co.uk/article/dogs-take-the-lead-in-reading-mood-t658d2l7x">Times</a>, Scott explained this divide in human-pet relations further by using recent studies where it was proven that dogs do not like to be hugged. 

One such study was conducted by Stanley Coren, a psychology professor and canine expert from the <a href="https://www.ubc.ca/">University of British Columbia</a>. 

According to an article in the <a href="http://www.telegraph.co.uk/science/2016/04/26/dont-hug-your-dog--it-hates-it-say-animal-psychologists/">Telegraph,</a> Coren analyzed images found on the internet of dogs being hugged looking for signs of distress such as avoiding eye contact, folding its ears away, or keeping its eyes closed. 

Coren found a large majority of the photographs showed that dogs were under stress while being cuddled or hugged.

“The dogs really like being with their owners, they want to be with their owners, but they don't want to be held. It provokes anxiety in them: as an animal, they want to be able to move freely,” Scott told the Times. “Dogs are great at reading us but we are pretty shocking at reading them.”

Researchers from the <a href="https://www.uzh.ch/en.html">University of Zurich</a> recently investigated how well people manage the boundaries between their work and personal lives. The study revealed that mixing work and pleasure can affect people's sense of well-being and lead to exhaustion.

The online analysis was focused on 1,916 employees from various sectors of German-speaking countries. Over 70 percent of the participants surveyed were married and their average age was 42.3 years. Half of the individuals worked 40 hours or more per week, and 55.8 percent of them were men. 

Participants were asked how well they were able to divide their work lives from their non-work lives. The subjects reported how often they took work home, how often they worked on weekends, and how often they thought about work during their time off.

In addition, the participants were asked whether they made time after work to relax, socialize, or to participate in sports or hobbies. They were also questioned about how much effort they put into keeping their <a href="https://www.earth.com/news/working-night-shift-obesity/">work</a> lives from interfering with their private lives. 

In order to measure a person's level of well-being, the researchers took into consideration the individual's sense of physical and emotional exhaustion as well as their sense of balance between work and home life.

The researchers found that employees who did not have a distinct separation between their work and home lives were less likely to participate in activities that could help them relax and recuperate after the demands of work. As a result, these individuals felt more exhausted and had a lower sense of well-being.

"Employees who integrated work into their non-work life reported being more exhausted because they recovered less," explained study lead author Ariane Wepfer. "This lack of recovery activities furthermore explains why people who integrate their work into the rest of their lives have a lower sense of well-being."

Wepfer said it is important to examine the findings of this research to improve occupational health. She believes that companies should have policies in place that may help employees balance their workload without affecting their personal lives.

"Organizational policy and culture should be adjusted to help employees manage their work-non-work boundaries in a way that does not impair their well-being," says Wepfer. "After all, impaired well-being goes hand in hand with reduced productivity and reduced creativity."

The study is published in Springer’s <a href="https://link.springer.com/journal/10869">Journal of Business and Psychology</a>.

Medical marijuana has been increasingly legalized in states across America, and has been a viable prescription drug for years. But there is some concern in the medical community about providers allowing kids to have access to medicinal cannabis as well.

A new study published in the journal Pediatrics analyzes the interdisciplinary provider perspectives on legal medical marijuana use in children with cancer. The findings reflect survey responses from almost 300 providers in Illinois, Massachusetts, and Washington. 

Pediatric oncology providers received frequent requests for <a href="https://www.earth.com/news/cancer-patients-medicinal-marijuana/">medical marijuana</a> for relief of nausea and vomiting, lack of appetite, pain, depression, and anxiety. The results of the survey showed that most providers considered medical marijuana more acceptable for use in children with advanced cancer or near the end of life than in the earlier stages of cancer treatment. 

This finding is consistent with the current American Academy of Pediatrics position that sanctions medical marijuana use for “children with life-limiting or seriously debilitating conditions.” The survey showed that only 2 percent of providers believed that medical marijuana was never appropriate for a child with cancer.

“It is not surprising that providers who are eligible to certify for medical marijuana were more cautious about recommending it, given that their licensure could be jeopardized due to federal prohibition,” says co-author Kelly Michelson, MD, a Critical Care physician at Ann &amp; Robert H. Lurie Children's Hospital of Chicago. Michelson also points out the institutional policies within hospitals may prohibit pediatric providers from facilitating medical marijuana access, due to compliance with federal laws. The survey found that almost one-third of providers received one or more requests for medical marijuana, and the greatest barriers to access are the lack of standards on formulations, dosing, and potency.

However, 92 percent of providers were willing to help children with cancer access medical marijuana – although providers who are legally eligible to certify for medical marijuana were actually less open to endorsing its use.

“In addition to unclear dosage guidelines, the lack of high quality scientific data that medical marijuana benefits outweigh possible harm is a huge concern for providers accustomed to evidence-based practice,” explains Michelson. “We need rigorously designed clinical trials on the use of medical marijuana in children with cancer.”

Research from <a href="https://www.vu.nl/en">VU Amsterdam</a> has found that the best decisions are made using the average of various estimates. Using data from Holland Casino promotional campaigns, experts set out to determine whether it is true that when people make estimates, the average of their estimates is relatively close to reality.

In 2013, 2014, and 2015, Holland Casino visitors could participate in an estimation contest during the last seven weeks of each year. The participant who came closest to guessing the number of pearls in a giant <a href="https://www.earth.com/news/sound-champagne-bubbles-quality/">champagne</a> glass won the amount of 100,000 euros. Over the course of three years, approximately 1.2 million people took part in the contests. 

"For our research, we analysed the three enormous datasets of these promotional campaigns,” said study co-author Martijn van den Assem. “The data showed that averaging all of the estimates yields significant accuracy gains. We also looked at the estimates of people who participated multiple times."

Over 100 years ago, British scientist Sir Francis Galton researched estimation contests that were similar to those held at Holland Casino. Through his own experimentation, Galton surprisingly found that averaging multiple estimates provides a relatively accurate outcome, a principle that is known as the Wisdom of Crowds principle. 

Recent studies have indicated that it is also useful to average estimates that come from the same person. When the research team analyzed the estimates by people who participated in the contest multiple times, they discovered that averages from the same person do work. They refer to this phenomenon as the “wisdom of inner crowds.”

This concept is appealing because it is often easier to make multiple estimates alone than it is to involve other people, and decision-makers have to rely on themselves to make a lot of different decisions. The findings of the study suggest that the best way to reach a good decision is to think it over at different times of the day, with a few nights of sleep in between.

However, accuracy is drastically improved when you take the average of estimates from different people. The experts determined that the average of a large number of estimates from the same person is rarely better than the average of just two estimates from different people. 

"For the quality of estimates, it is therefore better if two people are both engaged in the same two projects than when each focuses entirely on an individual project,” said study co-author Dennie van Dolder.

The study is published in the journal <a href="https://www.nature.com/nathumbehav/">Nature Human Behaviour</a>.

Potatoes have become such a food staple all over the world that it can be hard to imagine a time when they weren’t so ubiquitous. 

It is believed that Spanish conquistadors brought the potato back from South America to Spain in the mid-1500s, and it was Sir Walter Raleigh that first introduced the vegetable to Ireland in 1589. 

The <a href="https://www.earth.com/news/new-genetically-engineered-potatoes-approved/">potato</a> became a real mainstay in the early 1700s. Potato crops were abundant throughout Europe, and new research has revealed that this starchy vegetable helped keep the peace for centuries. 

According to a new report conducted by a team of U.S economists from <a href="https://www.harvard.edu/">Harvard</a>, <a href="http://www.northwestern.edu/">Northwestern University</a>, and the <a href="https://www.colorado.edu/">University of Colorado</a> and published by the <a href="http://www.nber.org/papers/w24066">National Bureau of Economic Research</a>, the introduction of potatoes helped reduce conflict in Europe for a minimum for 200 years. 

The economists spanned their research from 1400 to 1900, examining conflicts and casualties in  Europe and what impact crops and agriculture had, if any, on discord and civil feuds. 

The results show that the potato greatly reduced instances of civil unrest because there was an abundance of cheap, readily available nourishment.  

Potatoes have more caloric value and were an important food source for poorer citizens, and farming opportunities meant fewer disputes over land. 

“We find that the introduction of potatoes permanently reduced conflict for roughly two centuries. The results are driven by a reduction in civil conflicts,” say the authors in their report. 

The researchers were spurred by the questions surrounding agriculture and its impact on society beyond the obvious economic advantages. 

The report helps give a more thorough examination of agriculture in European history and could pave the way for expanding agriculture in lower income countries today as a means to reduce civil unrest and improve quality of life.

ShakeAlert is an earthquake early warning system that has been under development for over a decade, and may result in a U.S. West Coast prototype that could see limited public use in 2018. The system uses a dense network of seismic stations that transfer data to a central processing and alert system. The alert information is then distributed to users as an early <a href="https://www.earth.com/news/texas-earthquakes-dormant-faults/">earthquake</a> warning.

In two papers published in <a href="https://pubs.geoscienceworld.org/srl">Seismological Research Letters</a>, researchers detail the main components and testing platform for this prototype ShakeAlert system – which is currently being tested in California, Washington, and Oregon. 

“Parts of Los Angeles and San Francisco are covered pretty well by regional network stations, but many areas of California, Washington and Oregon are not covered very well,” explains Monica Kohler, a research faculty member at <a href="http://www.caltech.edu/">Caltech</a>. “There's some funding in the works to get some new stations in place, but right now it's not enough to complete the regional arrays that are necessary for earthquake early warning in its most robust form.”

This system was developed using seismic data collected by the Advanced National Seismic System (ANSS), which is a national collection of seismic networks supported by the U.S. Geological Survey. In total, roughly 760 seismic stations currently contribute to ShakeAlert. However, one of the top priorities for improving ShakeAlert is the addition of almost 1000 additional stations on the West Coast.

At the moment, the ShakeAlert system is testing the use of “volunteer” accelerometers – mainly in the Los Angeles area – which detect earthquakes and can be plugged in at a home or business, eliminating the need for a full-scale seismic station. The system’s algorithms also help determine a “point source” for an earthquake, but it’s still a work in progress. “We are working on the ability to incorporate algorithms that can handle very large earthquakes that happen in a way that can't be approximated to a single point,” says Kohler. The current system is not as successful at providing useful warnings for earthquakes that rupture a long section of a fault and evolve over time.

Along with providing earthquake warnings and pinpointing the point source, ShakeAlert is also now testing algorithms that provide data on how severe the ground is shaking for users at their exact location. While the system was developed for the West Coast, a similar system could be used for early earthquake warnings in places such as Hawaii, Alaska, or even Oklahoma. “We have been getting questions along the lines of ‘can we try your system where we live?’ or ‘can we port your system over?’” Kohler says. “The answer in theory is yes, but there have to be these certain key elements in place.”

The ShakeAlert team is currently working to get those elements in place, as well as perfect their current system on the West Coast. Improving and expanding this system may one day save the lives of many people in earthquake-heavy areas.

Dutch cheeses such as edam and gouda have been made for hundreds of years using complex starter cultures, and changes in the composition of bacteria strains makes the quality of these cheeses inconsistent. But now, a team of experts from Norway has developed a tool that can monitor these strains of bacteria with high resolution to maintain a better quality of cheese.

When bacterial strains in starter cultures become infected by viruses called bacteriophage, the quality of the cheese is sacrificed. This is a common problem in industrial cheese production, which uses "frozen batch inoculum.” 

Unlike traditional methods which use samples from previous cheese batches as starter cultures, frozen batch inoculum ensures that the <a href="https://www.earth.com/news/ancient-viruses-complex-life/">bacteria</a> will not vary. But while this method prevents unwanted bacterial changes, frozen batch inoculum fails to prevent bacteriophage evolution. Because of this, bacteriophage frequently gain the upper hand on the invariant bacteria.

Helge Holo is a professor of Microbiology at the <a href="https://www.nmbu.no/en">Norwegian University of Life Sciences</a>. Dr. Holo explained that close monitoring could promptly detect quality issues, and measures could be taken to correct these problems right away.

The newly developed tool could identify strains that are most important to cheese quality and those particular strains could be engineered to resist bacteriophage. In addition, other strains having similar influence on cheese quality that have less bacteriophage susceptibility could substitute for those that are more susceptible to bacteriophage, according to Dr. Holo.

For the investigation, the researchers isolated more than 200 strains of bacteria from three commercial starter cultures and sequenced the genomes of 95 of these strains. They then searched for the most variable gene that was present in all strains. 

The gene singled out by the team was epsD, a protein that is thought to be involved with resisting bacteriophage, which was present in 93 of the 95 strains. Each strain's epsD is slightly different from the others, so the bacterial strain can be identified from the epsD sequence.

The tool is also capable of quantifying the number of epsD sequences from a given strain, which allows experts to determine the number of bacteria of that strain that are present, which is a good indicator of any issues.

"The loss of abundance, or disappearance of an epsD sequence indicates that something has gone wrong," said Dr. Holo. "That could be a phage attack."

Dr. Holo said that bacteriophage are likely the ultimate cause of much of the fluctuation in quality that occurs in cheese cultures. The research is published in <a href="http://aem.asm.org/">Applied and Environmental Microbiology</a>, a journal of the <a href="https://www.asm.org/">American Society for Microbiology</a>.

Canola oil is marketed as being healthier for your heart than other oils – but it may come at the cost of your brain’s health and your waistline.

A new study by two <a href="https://www.temple.edu/">Temple University</a> researchers has found that canola oil may worsen memory loss in patients with Alzheimer’s disease, as well as damage their ability to learn new skills. It may also cause plaques linked to brain deterioration in people without the disease.

The oil may also be linked to weight gain, the researchers said.

“At this time point we found that chronic exposure to the canola-rich diet resulted in a significant increase in body weight and impairments in their working memory (among mice),” they wrote in their study.

This could be a problem, because canola oil is often offered up as a cheaper, heart-healthier alternative to olive oil, a key staple of the Mediterranean diet, the study said. The diet has been linked to a healthier heart, as well as a reduced risk of Alzheimer’s disease and cognitive impairment, the scientists said.

“Canola oil is appealing because it is less expensive than other vegetable oils, and it is advertised as being healthy,” co-author Dr. Domenico Praticò told the <a href="http://www.dailymail.co.uk/">Daily Mail</a>.

Praticò and his co-investigator Elisabetta Lauretti have studied the effects of extra virgin olive oil on brain health. When they found that there had not been a similar study on canola oil, they undertook it themselves.

They worked with mice that were genetically engineered to develop a disease similar to Alzheimer’s in humans. At six months, when the mice began showing symptoms, Praticò and Lauretti divided them into two groups. One was fed a large amount of canola oil each day, while the control group ate a normal diet.

After six months, the mice fed canola oil were measurably heavier, and their cognitive function was worse.

In the end, when choosing a cooking oil with health in mind, people should stick with olive oil or other oils with provable health benefits, Praticò and Lauretti said.

“While more studies are needed, our data do not justify the current trend aimed at replacing olive oil with canola oil,” the pair wrote.

The study has been published in the journal <a href="https://www.nature.com/articles/s41598-017-17373-3">Scientific Reports</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;

'The weather of Santiago resembles the Mediterranean climate with dry and warm summers with temperatures reaching up to 35°C (from October to March) and cool and humid winters that can drop to 0°C (from April to September)."



"The city lies in the centre of the country’s central valley around 80 km from the Pacific Ocean to the west and borders Argentina to the east. A tiny part of Argentina is visible in the top-right corner of the image where the mountain crest of the Andes Mountains acts as a divider between the two countries," says ESA.

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



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



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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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;
