Not long ago, the common belief was that only a subset of media consumers - often less educated and highly biased - would let their political allegiance override the truth. They would believe the news that favors their political inclinations, even if it wasn't authentic.



Then some intriguing studies emerged which indicated quite the opposite. The research suggested that media consumers across the spectrum value truth over partisanship.



The studies proclaimed that the authenticity of news was more influential than its alignment with a consumer's political views by more than four times.



However, as we stand on the brink of a national election fraught with misinformation, a fresh study shakes this understanding to its core.



<h2 class="wp-block-heading" id="h-news-and-political-views">News and political views</h2>



The research, led by top psychology scholars at Stanford University, suggests that the masses tend to prioritize partisanship over truth when <a href="https://www.earth.com/news/political-views-change-our-perception-of-the-past-and-future/" target="_blank" rel="noreferrer noopener">consuming news</a>.



Quite unexpectedly, this behavioral pattern spans across all political orientations, educational backgrounds, and reasoning capabilities.



Study lead author Michael Schwalbe is a postdoctoral scholar in the Department of Psychology at the School of Humanities and Sciences at <a href="http://www.stanford.edu/" target="_blank" rel="noreferrer noopener">Stanford University</a>.



"We saw an effect of people being more influenced by political alignment than truth," said Schwalbe. 



"We saw it on both political sides and even among people who scored well on a reasoning test. We were a bit surprised to see how widespread this tendency was. People were engaging in a lot of resistance to inconvenient truths."



<h2 class="wp-block-heading" id="h-pervasive-problem-across-political-parties">Pervasive problem across political parties</h2>



The researchers unearthed intriguing ways in which political views and partisanship can impact the analysis of news. 



In one measure of bias, people's beliefs about the impartiality of their political side compared to their rivals were assessed. Ironically, those who were most confident in their side's neutrality were the most biased.



Furthermore, partisanship seemed to have a more robust effect on <a href="https://www.earth.com/news/climate-change-opinions-swing-voting-and-elections-in-the-u-s/" target="_blank" rel="noreferrer noopener">processing real news</a> than fake news. People demonstrated a higher propensity to reject true information that challenged their political views and accept false information that supported their ideological stances.



"Everyone thinks it's the other person who is the problem," said Geoffrey L. Cohen, the James G. March Professor of Organizational Studies in Education and Business, professor of psychology in H&amp;S, and senior author of the study. 



"People say, 'Not me!' But it turns out, like with a lot of social psychological research, it's actually a pretty pervasive problem across political parties and up and down the educational ladder. The problem isn't just misinformation but the filters of our own mind - perhaps more so."



<h2 class="wp-block-heading" id="h-news-sources-and-political-beliefs">News sources and political beliefs</h2>



The study is based on research conducted on a sample of the voting-age U.S. population, matched to the demographics of the census. This group included supporters and opponents of former President Donald Trump.



A distinctive aspect of this research is its deviation in methodology from previous studies. According to Cohen, this could be why the findings contradict them. While the other studies used existing news headlines, this research involved fabricated ones.



Also, in prior investigations, subjects could see the news sources, which may have influenced their acceptance or rejection of the information, whereas this study focused on the headlines alone.



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



The research team conjured fake headlines like "Trump Beats Grandmaster Chess Champion" and "Trump Attended Private Halloween Gala with Sex Orgies Dressed as the Pope." 



Surprisingly, the experts discovered that Trump's supporters and opponents were more likely to believe headlines that aligned with their views than to accept <a href="https://www.earth.com/news/cities-are-largely-unprepared-for-the-effects-of-climate-change/" target="_blank" rel="noreferrer noopener">true headlines</a> that opposed their beliefs.



The researchers suggest that one contributing factor for this situation is the increased consumption of partisan media. 



"We found that the strongest predictors of bias include extreme views of Trump, a one-sided media diet, and belief in the objectivity and lack of bias of a person's own political side relative to the other side," Schwalbe said.



<h2 class="wp-block-heading" id="h-growing-concern-about-news-consumption">Growing concern about news consumption </h2>



The findings of this study underscore concerns about news consumption in the 21st century, especially with the advent of social media and the constant availability of political news. 



Gaining access to one-sided information has become easier, which can reinforce beliefs in personal objectivity and lead to deepened polarization over time.



<h2 class="wp-block-heading" id="h-possible-paths-to-improvement">Possible paths to improvement</h2>



Having identified the problem, the next logical step is to propose interventions. A measure suggested by Cohen, known as "pre-bunking," involves proactive fact-checking where media sources warn of potential misinformation, or people independently learn to recognize manipulation tactics.



However, Cohen and Schwalbe emphasized that the solution doesn't solely lie in policy changes focused on fake news; people are also biased in their disbelief of true news.



Accordingly, they highlight the significance of promoting intellectual humility, wherein media consumers acknowledge the fallibility of their minds and learn to question their perceptions.



"There's still much more to do to understand the problem," said Schwalbe. So, while this study forms a solid foundation for further exploration, there's no denying that we're only at the beginning of this investigative journey.



The study is published in the <a href="https://psycnet.apa.org/fulltext/2025-33892-004.html" target="_blank" rel="noreferrer noopener">Journal of Experimental Psychology: General</a>.

People trust news that matches their political views, even when it's fake

With the takeover of social media as a major outlet for news and information these days, it’s not surprising that it has become the leading destination for consumers to seek out information about plastic surgery. This is especially true of young people, many of whom are looking to improve their appearance for these social media platforms, such as Instagram and Snapchat. However, a recent study from Northwestern Medicine has found that the majority of providers advertising cosmetic surgery services on Instagram are actually not board certified-plastic surgeons. 

“This is a very scary finding,” says Robert Dorfman, first author of the study and a medical student at <a href="http://www.feinberg.northwestern.edu/">Northwestern University Feinberg School of Medicine.</a> “Providers – ranging from physicians who are not licensed in plastic surgery to dentists, hair salon employees and barbers – are doing procedures for which they do not have formal or extensive training. That’s extremely dangerous for the patient.”

A board-certified plastic surgeon is a physician who has over six years of surgical training and at least three years specifically dedicated to plastic surgery. Many plastic surgeons also specialize within the plastic surgery discipline. Despite this, many hair salons, dentists, barbers and spas are marketing plastic surgery procedures on <a href="https://www.earth.com/news/instagram-photos-reveal-depression/">Instagram</a>, even though they have no physician with the necessary experience.

“A cosmetic surgeon is not necessarily the same thing as a board certified plastic surgeon, and patients need to be made aware of this,” says Dorfman.

Someone who calls themselves a “cosmetic surgeon” could have experience ranging from one-year of cosmetic surgery fellowship to just a few short weekend courses covering cosmetic surgery topics.

The study’s authors believe that the confusing marketing on social media is putting patients at risk of physical harm and even death. A prior study done by Dr. John Kim, a Northwestern Medicine plastic surgeon, found a nearly 300 percent increase in the number of complications from a specific surgery when it was performed by non-plastic surgeons compared to board-certified surgeons.

This new study from <a href="http://www.feinberg.northwestern.edu/">Northwestern Medicine</a> analyzed the types of providers marketing cosmetic surgical procedures and used popular hashtags to identify related posts. From the top 189 posts with these hashtags, less than 20 percent of the providers had plastic surgeons eligible for membership in ASAPS. Non-eligible physicians made up over 26 percent. Just over 5 percent of the top posts were from non-physicians, including dentists, spas with no associated physicians, and even a hair salon. The rests of the posts were mostly self-promotional or educational.

“As patients increasingly rely on social media to choose their provider, it is critical to understand the ecosystem of online platforms available to patients,” says Dr. Clark Schierle, a plastic surgeon at <a href="http://www.feinberg.northwestern.edu/">Northwestern Medicine</a>. “It is critical that board-certified plastic surgeons use social media like Instagram as a platform to educate patients about the risks of surgery.”

Heart disease is the leading cause of death in the United States, and is most commonly caused by plaque buildup in the arteries. This constricts blood flow, which leads to heart attack, heart failure, or stroke. Now, a new 16-year study from <a href="http://www.lunduniversity.lu.se/">Lund University</a> set out to examine how weather could have a possible triggering effect for heart attacks. The research found a direct correlation between cold weather conditions and an increase in heart attacks. 

The study gathered data from 280,000 patients who were treated for heart attacks and matched the corresponding <a href="https://www.earth.com/news/weather-temperature-election-outcomes/">weather</a> conditions from meteorological records.

Between the 1998 and 2013, the <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2811455/">Swedish Myocardial Infarction Registry</a> recorded 280,873 heart attacks treated at a coronary care unit. The study compared these incidences with the weather conditions at the time and grouped together the heart attacks that occurred in similar weather conditions and temperatures.

The results showed that cooler temperatures triggered a higher rate of heart attacks, but the number of heart attacks decreased in warmer temperatures. Researchers found that when the average temperature was below 0 degrees Celsius, there were 4 or more heart attacks per day. 

“Our results consistently showed a higher occurrence of heart attacks in sub-zero temperatures. The findings were the same across a large range of patient subgroups, and at national as well as regional levels, suggesting that air temperature is a trigger for heart attack,” said Dr. Moman A. Mohammad from the Department of Cardiology at Lund University, first author of the study. 

A possible explanation for this swell in heart attacks could be because blood vessels constrict in colder temperatures, which increases blood pressure. 

Because this was an observational study, other outlying factors may have also had an impact on the increased number of heart attacks. 

Even so, the study shows that colder temperatures are a possible trigger for heart attacks, so people at risk of cardiovascular disease and heart problems should take extra precaution during the winter months.

Becoming the primary caregiver for a family member can be incredibly exhausting and stressful, mentally, physically, and emotionally. The dynamic is complicated further when one must become the primary caregiver for their spouse. Despite the often overwhelming burdens of caregiving, studies also show that helping and caring for others improves our wellbeing and can be greatly beneficial to mental health.  

Now, a new study from the <a href="http://publichealth.yale.edu/">Yale School of Public Health</a>, <a href="http://www.stonybrook.edu/">Stony Brook University</a>, the<a href="https://umich.edu/"> University of Michigan</a>, and the <a href="http://www.buffalo.edu/">University at Buffalo</a> set out to investigate this dichotomy in caregiving and find the parameters that lead to greater fulfillment and improved well-being to lessen the negative, demanding effects. 

The researchers conducted two studies and observed caregivers whose spouses suffered chronic pain. The first study included 73 caregivers who reported on their tasks and emotional state every three hours. In the second study, participants were asked to write in a diary at the end of the day fully describing their activities and how much they felt appreciated. 

The researchers, led by Michael Poulin from the University at Buffalo Department of Psychology, found that helping behaviors can reduce <a href="https://www.earth.com/news/cortisol-indicate-stressed/">stress</a>, but appreciation and recognition for the tasks given is a key part of the equation. 

“Spending time attempting to provide help can be beneficial for a caregiver's mental and physical well-being, but only during those times when the caregiver sees that their help has made a difference and that difference is noticed and recognized by their partner,” said Poulin.

The study found that being a caregiver and engaging in helping behaviors can be rewarding and actually decrease the stresses of caregiving. However, these benefits are only truly felt when gratitude is adequately expressed by the beneficiary. 

Poulin’s study is important in that it shows how to alleviate the some of the stress of caregiving. The findings could also help implement social programs and community resources that help caregivers and their spouses properly communicate and make sure emotional needs are met for both parties.

Calculating the financial return on education is increasingly difficult these days, especially since there aren’t many set ROI (return on investment) measuring techniques that tackle the financial benefit of higher learning and any economic gains that ensue, compared to the costs of schooling. But a new study examined the investment return for higher educated women and how their standard of living was effected in the labor and marriage markets, and examined why so many women are marrying down compared to men. 

“Now women are more likely to get married to a less-educated man. What is the consequence of this?” asks ChangHwan Kim, associate professor of sociology at the <a href="https://www.ku.edu/">University of Kansas</a> and lead author of the study, which was published in the journal Demography. 

The researchers gathered US Census data from 1990, 2000,  and 2009-2011, and examined people ages 35 to 44 years old to study gender-specific changes in the financial return on education. 

The number of educated women has greatly increased in the past few decades and opened more opportunities in the labor market. Previously, this worked in women’s favor, but now there are far more highly educated women compared to men in the marriage market, making it easier for men to marry up. 

“Previously, women received more total financial return to education than men, because their return in the marriage market was high. However, this female advantage has deteriorated over time despite women's substantial progress in education and labor-market performance,” said Kim. 

The researchers found that even with the greater economic advantage that women are bringing to the marriage market, many women are faced with a lower standard of living because the financial contributions to the marriage household are not equal. 

“For less-educated women, the contribution of their husbands has been substantially reduced so that their standard of living has diminished, even though their personal earnings have grown,” the researchers said.

Another way to look at the study’s results, as the researchers note, is that men can marry up easily and gain more from the return to education versus their spouses. The study shows a greater improvement in the standard of living for men than women. 

“When we consider family dynamics, men are getting the benefit from women's progress,” said Kim. 

Calculating the financial benefits of <a href="https://www.earth.com/news/continued-education-stay-sharp/">education</a> is important because it can help put the costs of education in perspective for future students. But understanding any possible wealth disparities and gaps by factoring in gender dynamics is an important piece to bear in mind.

A massive investigation of more than 135,000 people across five continents has revealed that a diet which includes a moderate intake of fruits, vegetables, and fat is linked to longer life. The research also suggests that excessive consumption of carbohydrates can increase the risk of death. 

The highest benefits were found in people who incorporated three to four servings of fruits, <a href="https://www.earth.com/news/labeling-make-vegetables-appealing/">vegetables</a> and legumes into their diet every day. Victoria Miller is a <a href="http://www.mcmaster.ca/">McMaster University</a> doctoral student and lead author of the paper.

"Our study found the lowest risk of death in those who consumed three to four servings or the equivalent to 375 to 500 grams of fruits, vegetables and legumes per day, with little additional benefit for intake beyond that range," said Miller. "Additionally, fruit intake was more strongly associated with benefit than vegetables.”

A higher amount of fat, enough to provide 35 percent of energy, was also found to contribute to a lower risk of death compared to lower fat intakes. A diet high in carbohydrates, on the other hand, proved to be dangerous. Eating enough carbohydrates to provide 60 percent of energy or higher was linked to an increase in the risk of death, although not from cardiovascular disease.

The data for the analysis was collected from the Prospective Urban Rural Epidemiology (PURE) study, which followed more than 135,000 people in 18 countries. The study gathered information about the participants’ diets and followed them for an average of seven and half years.

There was no relationship found between dietary fats and major cardiovascular disease, but higher fat consumption was associated with lower mortality. The data included all major types of fats including saturated fats, polyunsaturated fats, and monounsaturated fats. Saturated fats were associated with lower stroke risk.

Co-author Mahshid Dehghan pointed out that the results of the study contradict “the conventional beliefs about dietary fats and clinical outcomes.” She explained that recent dietary guidelines have focused on reducing fat intake in order to reduce the risk of cardiovascular disease without taking into consideration how saturated fat is replaced in the diet.

"A decrease in fat intake automatically led to an increase in carbohydrate consumption and our findings may explain why certain populations such as South Asians, who do not consume much fat but consume a lot of carbohydrates, have higher mortality rates," said Dehghan.

The research, published as two reports in <a href="http://www.thelancet.com/">The Lancet</a>, may help to better inform consumers of their nutritional needs.

"The findings of these studies are robust, globally applicable and provide evidence to inform nutrition policies,” said co-author Andrew Mente. “This is relevant because in some parts of the world nutritional inadequacy is a problem, whereas in other parts of the world nutritional excesses may be the problem.”

The reports will be presented today at the <a href="https://www.escardio.org/Congresses-%26-Events/ESC-Congress">Congress of the European Society of Cardiology</a> in Barcelona, Spain.

According to a new study from the <a href="https://www.escardio.org/Congress-Home">European Society of Cardiology</a>, poor sleep can lead to heart disease. Lack of quality sleep may be a sign of a serious cardiovascular issue such as ischaemic heart disease and stroke. Researchers conducted a study of almost 13,000 people to determine if there are distinguishable sleep disturbance patterns associated with each of these heart conditions.

"Poor sleep is associated with cardiovascular diseases such as ischaemic heart disease and stroke but the kind of sleep disturbances that are most risky is not well documented," said lead researcher Dr Nobuo Sasaki. "'Poor sleep' includes too short or too long sleep, difficulty falling asleep, and difficulty maintaining sleep."

In order to investigate the different patterns of sleep disturbance between the two conditions, the researchers analyzed 12,876 residents of Hiroshima, Japan, who were scheduled for a regular health check. 773 of the patients had a history of ischaemic heart disease, while 560 patients had a history of stroke. The remaining 11,543 had no cardiovascular disease.

The team evaluated <a href="https://www.earth.com/news/rem-sleep-risk-dementia/">sleep</a> habits of the patients using the Pittsburgh Sleep Quality Index (PSQI), a self-reporting survey about sleep quality which produces seven component scores. These scores measure aspects of sleep such as sleep duration, sleep quality, difficulty in maintaining sleep, and use of sleeping pills.

The experts calculated a global PSQI score which ranged from 0 to 21 for each patient using the sum of the seven component scores. Higher scores indicated poorer sleep quality. These “poor sleep" ratings were found in 52 percent of patients with ischaemic heart disease and 48 percent of patients with a history of stroke.

"The proportion of people suffering from sleep disturbances is around 1.5-fold higher among patients with previous ischaemic heart disease or stroke compared to those with no history of cardiovascular disease,” explained Dr. Sasaki.

"Interestingly only patients with ischaemic heart disease reported difficulty maintaining sleep and short sleep duration," he continued. "Difficulty maintaining sleep reflects an increase in sleep fragmentation, which refers to brief moments of waking up and causes overactivity of the sympathetic nervous system and adrenocortical axis."

The findings of the study will be presented today at the <a href="https://www.escardio.org/Congresses-%26-Events/ESC-Congress">Congress of the European Society of Cardiology</a> in Barcelona, Spain.

White shark sightings off the coast of Massachusetts startled beachgoers and closed multiple <a href="https://www.earth.com/news/sharks-cape-cod-rising/">Cape Cod</a> beaches last week. Experts say the sharks are most likely arriving to the area in pursuit of seals, and do not pose a major threat to humans.

Cleveland Bigelow was paddleboarding approximately 30 yards off the shore of Marconi Beach when he was thrown off his stand-up board by a white shark. The shark bit the board, but Bigelow escaped without injury. 

"I would be telling you a fish story if I said that I wasn't scared," Bigelow told <a href="http://www.wcvb.com/">WCVB</a>. "I count my blessings from God.”

14 miles south of the incident, a white shark attacked a seal just feet from the shore at Nauset Beach. Surfers and swimmers panicked to get to safety as a large pool of blood appeared in the water.

In recent years, great whites have been appearing in larger numbers off Cape Cod in the summertime. Researchers believe that they are attracted to a thriving seal population, which has been growing since the 1972 federal Marine Mammal Protection Act. Scientists also believe that changing ocean currents and the depletion of food due to overfishing are also explanations for the presence of more white sharks in the region.

Marie Levine is the executive director of the <a href="https://www.sharks.org/">Shark Research Institute</a> in Princeton, New Jersey.

"We are the interloper in the ocean," Levine told the <a href="https://www.ap.org/en-us/">Associated Press</a>. "White sharks prey on seals. Seals come ashore, so if seals are coming ashore on any beach, people should stay out of the water there. It's just common sense."

Greg Skomal is a state biologist in Massachusetts who has been studying the migratory patterns of white sharks. His team has electronically tagged dozens of animals for their research, and identified 80 sharks off Cape Cod in 2014, 141 in 2015, and 146 in 2016. 

While data for 2017 is not yet available, Skomal said there is evidence that great whites are spreading out to cover most of Cape Cod’s eastern coast. He indicates, however, that the event at Nauset Beach is a perfect example of why there is no need to panic.

"We had people who were surfing, we had swimmers, and we had a shark attack a seal among them all," said Skomal. "That's a level of selection that we need to realize. The shark decided the seal was the prey item."

There have been no fatal shark attacks reported in the United States so far this year, and sharks have not killed a person in Massachusetts since 1936.

Polyphenols play an important role in our health and well being as they are known to help reduce the risk of cardiovascular disease, protect against unwanted pathogens, and reduce cancerous tumors. Polyphenols are everywhere, especially in cocoa, olive oil, apples, grapes, and cherries. Now, a new study by the <a href="https://www.escardio.org/">European Society of Cardiology</a> has found that dark chocolate enriched with extra virgin olive oil is linked to a lower risk of cardiovascular disease, as extra virgin olive oil and cocoa are both high in polyphenols. 

The team of researchers tested the differing effects of dark chocolate with extra virgin <a href="https://www.earth.com/news/frying-food-olive-oil-health/">olive oil</a> and the Italian Panaia red apple, which also has high levels of polyphenols. 

“Fruits and vegetables exert their protective effects through plant polyphenols, which are found in cocoa, olive oil, and apples. Research has found that the Italian Panaia red apple has very high levels of polyphenols and antioxidants,” said Dr. Rossella Di Stefano, a cardiologist at the <a href="https://www.unipi.it/index.php/english">University of Pisa</a>, Italy and the lead author of the study. 

Dr. Di Stefano observed the effects that polyphenol-rich foods had on individuals with cardiovascular risk factors, and whether polyphenols inhibited atherosclerosis progression. Atherosclerosis is the slow buildup of fatty deposits or plaque that, over time, clog arteries and can have fatal consequences. 

The study followed 14 men and 12 women with cardiovascular risk factors. The participants were then were given 40 grams of dark chocolate for 28 days. The chocolate was enriched with either extra virgin olive oil or Panaira red apple and was given for 14 consecutive days each. 

The participants were also subject to urine and blood tests before and after the study. The researchers found that after the study was completed, the dark chocolate with olive oil had a significant impact on cardiovascular health. 

The researchers found increased EPC, or endothelial progenitor cells, which are important for vascular repair.

“We found that small daily portions of dark chocolate with added natural polyphenols from extra virgin olive oil was associated with an improved cardiovascular risk profile. Our study suggests that extra virgin olive oil might be a good food additive to help preserve our 'repairing cells', the EPC,” said Dr. Di Stefano.

Climate change will cause a major shift in the patterns of electricity consumption in Europe, according to a team of scientists from the United States and Germany. A higher demand for air conditioning will put more pressure on power grids that are already strained.

The researchers used hourly electricity usage data from 35 countries in Europe. These countries are all connected by the world's largest synchronous electrical grid. The research team investigated how changes in climate could influence the intensity of peak load events and overall power usage.

The study revealed that if <a href="https://www.earth.com/news/rainfall-carbon-emissions-soil-microbes/">carbon emissions</a> continue at the current rate, the highest demand for European power will shift from countries like Sweden or Norway to countries like Portugal or Spain, and in most countries the annual peak load will shift from winter to summer by the end of the century.

Leonie Wenz from the <a href="https://www.pik-potsdam.de/pik-frontpage">Potsdam Institute for Climate Impact Research</a> is the lead author of the study. He explained that the patterns of electricity consumption turned out to be very similar across all of the European countries that were examined. 

"We use this common characteristic as a basis for estimating future electricity consumption under climate change - that is beyond the current temperature range,” said Wenz. “That way, those European countries that are already experiencing very hot temperatures today serve as examples for the future of cooler countries.”

Co-author Max Auffhammer from the University of California, Berkeley, said that
“quantifying the connection between heat and human behavior is at the frontier of climate change research.”

“There now is ample evidence that when it's hot outside, air quality suffers, people are more stressed, aggressive, violent and less productive, mortality and crime rates rise,” said Auffhammer. “All sectors of the economy are affected by thermal stress, from the residential to the commercial, agricultural to the industrial sector.” 

Auffhammer explained that the automatic way that humans respond to high outdoor temperatures is to cool their indoor environments, which requires the consumption of large amounts of electricity. 

“This increased demand for air conditioning will put pressure on electricity grids when it is hot outside and generation and transmission infrastructure are already strained," he added.

The study, published in the <a href="http://www.pnas.org/">Proceedings of the National Academy of Sciences</a>, revealed that overall electricity consumption of Europe will not be affected by climate change, but the shift in seasonal and spatial usage will create major challenges.

"This will have important ramifications for the transmission infrastructure, peak-generating capacity and storage requirements - to adapt to the warming that is already unavoidable due to past greenhouse gas emissions,” said co-author Anders Levermann. “The easiest way to limit the impacts of climate change remains to keep the Paris climate guardrail, that is to limit the temperature increase to well below 2 degrees Celsius."

People in the United States consume 400 million cups of coffee per day, which translates to about 146 billion cups per year. Now, a new study from Barcelona has found some good news for coffee lovers, as higher coffee consumption was associated with a lower risk of death. The study’s results concluded that coffee could be beneficial part of a healthy diet. 

The study used data from the <a href="https://www.unav.edu/departamento/preventiva/sun">Seguimiento Universidad de Navarra</a> (SUN) project, a study that began in 1999. The researchers used the SUN project to examine 20,000 people, focusing on their food preferences, coffee consumption, lifestyle, and sociodemographic characteristics, as well as previous health conditions. 

The researchers followed up with the participants for 10 years, looking at mortality rates and decreasing health conditions. The results concluded that within the ten year period, participants who drank more coffee had a lower risk of death. 

Specifically, the researchers determined that those who drank four cups of coffee a day had a 64% lower risk of death compared to those who never drank coffee. For every cup of coffee consumed on a daily basis, the higher the percentage of lowering the risk of mortality. 

The researchers did make sure to factor in other considerations, such as adherence to the <a href="https://www.earth.com/news/new-study-proves-eat/">Mediterranean diet</a> and socioeconomic features to see if drinking coffee was at all correlated. But ultimately they discovered a distinct connection between higher coffee consumption and a longer lifespan. 

“In the SUN project, we found an inverse association between drinking coffee and the risk of all-cause mortality, particularly in people aged 45 years and above. This may be due to a stronger protective association among older participants,” said Dr. Adela Navarro, a cardiologist at <a href="http://www.cun.es/en/">Hospital de Navarra,</a> Pamplona, Spain.

For anyone looking to adopt a pet, it can be overwhelming to decide which companion will best complement your lifestyle. Animals have personalities as colorful and diverse as people, and finding the right pet can make a big difference in your life. 

Studies have shown that <a href="https://www.earth.com/news/difference-animal-shelters-rescues/">pet</a> owners are happier and healthier than people who do not have pets. You want to give your pet a great quality of life as well, and that comes very naturally if you select a furry friend who is compatible with your personality. 

German Shepherds

For the disciplined and driven person, you need a pet who is every bit as capable as you are. Known for their obedience, German Shepherds are intelligent and hardworking. You are too focused on your goals to worry about being popular, and the socially reserved German Shepherd will not mind at all.

Labrador Retriever

If you are an outdoors person who is friendly and inquisitive, you need a Labrador Retriever by your side. These outgoing dogs never meet a stranger, and they are athletic and playful enough to keep up with your energetic lifestyle. This match is even more ideal if you are drawn to the water, as Labrador Retrievers are excellent swimmers.

French Bulldogs

If you are laid back, reserved, and your idea of exercise is a quiet walk in the evening, you need a French Bulldog. He does not require a ton of exercise and is happy just chasing a ball while you watch the television. In fact, your French Bulldog will grow into quite the couch potato in his adult years. He is mainly quiet and politely unsociable, just like you.

Siberian Huskies

On the other hand, if you are an extroverted daredevil with a love for the mountains, the Siberian Husky makes the perfect sidekick. These dogs thrive in cold weather and love rugged hikes and hard work. They are gentle, good-natured, and alert, yet not overly suspicious or aggressive. They love the company of humans and will fit right in with your adventurous group of friends.

Cavalier King Charles Spaniels

For the quiet homebody who is affectionate and easygoing, your match made in heaven is  the Cavalier King Charles Spaniel. These dogs are sweet and compassionate and get along with everyone. The only thing your little dog will love as much as lying in your lap is sleeping in it. This gentle dog just goes with the flow and lives in the moment.

Cats

Despite how perfect some of these dog breeds may be for your personality, if you are too busy to devote time to a dog then you may want to consider adopting a more independent pet. Cats, for example, may be a better fit for the person who is never home. Some breeds such as Siamese cats and Burmese cats, however, depend more on human contact than others.

The best approach to adopting a pet is to do your research. If you have children or other pets, it is important to learn about the temperament of an animal before bringing it home. Some shelters will let you walk a dog or even take it for a hike, which is a great way to get to know a new animal. 

<a href="https://www.petfinder.com/">Petfinder.com</a> offers a searchable list of pets from over 12,000 shelters and rescue groups in the the United States, Canada, and Mexico. Here you can search for birds, cats, dogs, and even horses which are available for adoption in your local area. No matter what animal you decide to adopt, just remember that by adopting you are saving a life, and finding the right pet can drastically improve your life as well.

According to a new study from <a href="http://drexel.edu/">Drexel University</a>, losing a consistent amount of weight from week to week actually increases sustained weight loss for longer. 

Researchers asked 183 people who were overweight or obese to enroll in a year long weight loss program that replaced meals. They asked members to self-monitor and count calories, increased physical activity, and had weekly weigh-ins and group sessions. 

The participants were then weighed two years after the program was completed to monitor if their <a href="https://www.earth.com/news/higher-incomes-more-exercise/">weight loss</a> efforts were sustained outside of the program. 

The study found that participants who had lost more weight in the first few weeks, or whose weights fluctuated, were less likely to have stayed on track two years later and had poorer weight loss results with the final weigh in. Conversely, those who had sustained a regular results early on, losing the same amount of weight from week to week, had better results two years later. 

Researchers also discovered that negative food behaviors like emotional eating or binge eating didn’t affect the results, as those who weren’t prone to those behaviors had uneven results and lost fewer pounds by the end of the study. 

According to the study,  sustained weight loss from week to week will yield the best results. 

“Settle on a weight loss plan that you can maintain week in and week out, even if that means consistently losing ¾ of a pound each week,” said Michael Lowe, a psychology professor at Drexel.

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



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



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

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



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



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

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



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



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



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

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



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



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

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



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



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

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



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



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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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



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



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



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth.

Satellites reveal how Earth's systems are interconnected

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



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



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



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



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

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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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

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



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



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



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



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