A walk through a park, a moment of quiet under a tree, a glimpse of green spaces from a window - these small encounters with nature might be more than just pleasant distractions. They could be changing people's lifestyle choices.



Researchers from the University of Exeter have found a link between nature and health habits. The study, part of the BlueHealth <a href="https://bluehealth2020.eu" target="_blank" rel="noreferrer noopener">project</a> funded by the EU’s Horizon 2020, tracked smoking and <a href="https://www.earth.com/news/why-social-drinking-feels-so-different-from-drinking-alone/" target="_blank" rel="noreferrer noopener">drinking patterns</a> across 18 countries.



The results were clear. People living in the greenest neighborhoods were 13 percent less likely to smoke and 31 percent less likely to drink daily than those in less <a href="https://www.earth.com/news/urban-green-spaces-are-urgently-needed-across-the-global-south/" target="_blank" rel="noreferrer noopener">green areas</a>.



<h2 class="wp-block-heading" id="h-nature-visits-reduce-smoking">Nature visits reduce smoking</h2>



The study didn’t stop at measuring green space. It also looked at intentional <a href="https://www.earth.com/news/cities-in-the-global-south-have-far-less-green-space/" target="_blank" rel="noreferrer noopener">nature</a> visits. People who made it a habit to spend time in nature - at least once a week - were less likely to smoke. The effect on drinking wasn’t as strong.



“We don’t think it’s simply a coincidence those who are exposed to nature smoke and drink less. A growing number of studies are showing that when people are exposed to nature, they have fewer cravings for substances like alcohol and nicotine,” noted Dr. Mat White from the <a href="https://www.univie.ac.at/en/" target="_blank" rel="noreferrer noopener">University of Vienna</a>.



“In part, we think this is because they tend to be calmer and don’t need that 'hit,' which helps them give up smoking, for instance.” 



<h2 class="wp-block-heading" id="h-what-counts-as-green-space">What counts as green space?</h2>



The study defined residential green space as land with <a href="https://www.earth.com/news/earth-day-2025-what-were-really-fighting-for/" target="_blank" rel="noreferrer noopener">natural elements</a> within 250 meters of a person’s home. That includes private gardens, parks, and patches of greenery. Data came from the BlueHealth International Survey, which involved 18,838 adults from 18 countries.



Study lead author Dr. Leanne Martin emphasized that the benefits of nature cut across income levels and educational backgrounds.



“Our finding that nature seems to be beneficial to all in society is hugely important because it goes some way to leveling the playing field in terms of reducing health inequalities,” noted Dr. Martin.



“We've accounted for a wide range of socioeconomic factors in our research and found the benefits are not determined by things like having a higher income or living in more affluent areas. For those people who don’t live in areas with high green space, we’ve found those intentional visits to nature also have huge benefits.”



<h2 class="wp-block-heading" id="h-green-spaces-can-assist-public-health">Green spaces can assist public health</h2>



The study suggests that <a href="https://www.earth.com/news/surprising-mental-health-benefits-of-living-near-green-spaces/" target="_blank" rel="noreferrer noopener">green</a> spaces could serve as a public health tool. Nature’s calming effect may reduce cravings for cigarettes. The tranquility of a park, the rhythm of a river, or the rustle of leaves could all play a role in easing the urge to smoke. 



But what about alcohol? The study found that while living near green spaces was linked to less daily drinking, the effect was not as strong as it was for smoking. 



Researchers think social habits may be a factor. Drinking often happens in social settings, and those settings might still be present, even in green areas.



<h2 class="wp-block-heading" id="h-can-nature-help-you-break-a-habit">Can nature help you break a habit?</h2>



Public health programs could use these findings. Instead of conventional quit-smoking strategies, they could promote nature visits. A weekly walk through a forest or a park might offer the same calming effect as nicotine - without the health risks.



But what about those without easy access to green spaces? The study suggests that intentional nature visits work, even for people in urban areas. Programs could organize nature outings or create small green spaces in city centers.



<h2 class="wp-block-heading" id="h-why-this-study-stands-out">Why this study stands out</h2>



Previous studies often focused on one country or one type of nature exposure. This study expanded the scope. It covered 18 countries and looked at both residential green space and intentional nature visits.



Despite the cultural and environmental differences across countries, the findings remained consistent. The link between green spaces and lower smoking rates held up across the board. This suggests that nature’s influence isn’t tied to one place or culture - it’s universal.



<h2 class="wp-block-heading" id="h-more-than-just-green-space">More than just green space</h2>



The study lays the groundwork for future research. It opens questions about how much nature is needed to see a health effect. Would a short walk through a park have the same impact as a day spent hiking? Would sitting by a lake offer more benefits than a walk through a garden?



And what about other health risks? If nature can lower smoking rates, could it also reduce other unhealthy habits? More research could explore these questions and refine the role of nature in public health strategies.



<h2 class="wp-block-heading" id="h-green-spaces-and-healthier-habits">Green spaces and healthier habits</h2>



The <a href="https://www.exeter.ac.uk" target="_blank" rel="noreferrer noopener">University of Exeter</a> study offers a simple message: green spaces might help people smoke and drink less. Living near greenery or visiting nature regularly seems to make people less likely to reach for a cigarette or a drink.



For public health officials, the findings suggest a low-cost, accessible intervention. Create more green spaces. Promote nature visits. Make nature a regular part of daily life.



For individuals, the takeaway is even simpler. Spend time in nature. Visit a park. Walk through a garden. It could be more than just a relaxing break - it could be a step toward a healthier life.

Living near nature helps reduce bad habits like smoking

A walk through a park, a moment of quiet under a tree, a glimpse of green spaces from a window - these small encounters with nature might be more than just pleasant distractions. They could be changing people's lifestyle choices. Researchers from the University of Exeter have found a link between nature and health habits. The study, part of the BlueHealth project funded by the EU’s Horizon 2020, tracked smoking and drinking patterns across 18 countries. The results were clear.

Babies’ ability to learn new and life-changing skills quickly is extremely important for their overall development. How they are able to do this is a question that has intrigued psychologists for years. According to new research from <a href="http://www.psu.edu/">Penn State University</a>, babies’ brains may have been preparing for these new skills long before they are observed using them.

The study was published in <a href="http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1467-8624">Child Development,</a> and supports long-standing but untested beliefs about infant development. Famous child psychologist Jean Piaget previously theorized that young children develop in bursts, rather than consistently over time. Using new modeling methods, <a href="http://www.psu.edu/">Penn State</a> professor of psychology Koraly Perez-Edgar was able to examine how behavioral development is related to growth in brain activity.

In a study involving 28 six-month-old infants over a seven-month period, the researchers had the subjects participate in a cognitive “a-not-b” task that measured their understanding of object permanence. This task involved hiding a toy in front of the infant and seeing if they were able to retrieve it.

“How babies perform in this task tells us a lot about their development because it's a coordination of multiple skills,” says Leigha MacNeill, a graduate student in psychology at <a href="http://www.psu.edu/">Penn State</a>. “They have to remember where the ball was moved, which is working memory. They have to know an object exists even though it’s out of sight, and they need to track objects moving in space from one place to another. All of this also required them to pay attention. So there’s a lot going on.”

Along with this task, the infants’ EEG was measured on each visit – with electrodes measuring electrical activity in different regions of the <a href="https://www.earth.com/news/exercise-brain-major-boost/">brain</a>. Data analysis showed that an infant’s performance on the a-not-b task developed in bursts, usually with big spikes around seven and eleven months. However, results showed that EEG power grew steadily throughout the seven months.

“Psychologists have been suggesting that while on the surface development looks like these quick bursts, underneath there may be very continuous, slowly developing mechanisms that one day look like they popped out of nowhere,” Perez-Edgar explains. “Like with kids learning to talk, it looks like they learn all these words overnight, but they’ve been listening and thinking and processing for a long time.”

Along with studying infants’ behavioral development, the study served to observe what is also happening in their brains during this important growth period.

Study reveals how infants learn important life skills so quickly

Among the many disastrous consequences that could arise if climate change continues at its current rate, a new study from the <a href="https://www.umich.edu/">University of Michigan</a> reveals that an especially worrisome impact may be on the horizon; the disappearance of our natural sources of maple syrup.

<a href="https://www.earth.com/plants/hybrid-sugar-maple-acer-leucoderme-saccharum-2/">Sugar maples</a> are known for their beautiful fall foliage, as well as being our main source of maple syrup. They also happen to be the dominant tree species in the northern hardwood forests of eastern North America, including in the Great Lakes region. Researchers have recently found that with the forecasts of warmer temperatures and increased likelihood of summer drought in the Upper Great Lakes region, the sugar maples and other trees in that area will be put under a lot of additional stress.

On the flip side, forests around the world will be exposed to rising levels of nitrogen compounds generated by cars, power plants, factories, agriculture, and other human sources. While it’s considered a pollutant, these nitrogen compounds actually have a fertilizing effect on trees, and help promote growth. For years, climate scientists and forest ecologists have wondered whether the fertilizing effects of human-derived nitrogen would be enough to offset the additional stresses of a warmer, drier climate. Previous studies have produced contradictory results.

This new study, published in the journal <a href="http://esajournals.onlinelibrary.wiley.com/hub/journal/10.1002/(ISSN)1939-9170/">Ecology</a>, uses 20 years of data from four forest sites in both of Michigan’s peninsulas, and ultimately finds that nitrogen from human activities “will not fully compensate for the negative effects of growing under the drier forecasted climates.” As climate change marches on, the authors state that residents of the state should see a decrease in growth of sugar maples. Additionally, it appears that if the more extreme climate predictions hold true, sugar maples will eventually disappear from Michigan’s Lower Peninsula entirely.

“Under extreme climate scenarios, the increase in nitrogen won’t be able to compensate for decreased growth of sugar maples due to lack of water,” says Inés Ibáñez, an associate professor and forest ecologist at the University of Michigan.

Losing these trees would likely be a positive feedback loop, as the world’s forests remove about one-quarter of the carbon dioxide emitted into the atmosphere by the burning of fossil fuels. Fewer trees means more carbon dioxide in the atmosphere, further exacerbating the greenhouse gas problem. 

“That’s why these questions about forest growth are so important,” says Donald Zak, a professor at the University of Michigan. “And the only way to get some of the answers is through the type of long-term ecological research used in this study.”

For their study, the researchers analyzed the combined effects of soil moisture, summer temperature, and nitrogen deposition on the growth of sugar maples from four different sites in Michigan. This encompassed records from more than one thousand trees over a period of roughly 20 years.

Are you guilty of micro-cheating? According to psychologist Martin Graff, <a href="https://www.earth.com/news/social-media-helping-communities-manage-fires/">social media</a> is changing the nature of relationships, and our actions online can be just as damaging as having a physical affair. 

Micro-cheating is a relatively recent concept and attempts to define the lines between being casual and friendly online and pursuing outside romantic interests while in a relationship. 

Examples of micro-cheating include checking up an ex-partner’s Facebook profile, adding them on Snapchat or Instagram, messaging them without your partner’s knowledge, or showing too much interest on social media.

“In terms of the history of human communication and relationships this is all brand new,” Graff told <a href="http://www.telegraph.co.uk/news/2018/01/15/micro-cheating-social-media-tearing-couples-apart-scientists/">The Telegraph.</a> “Social media interactions have an inherent ambiguity. Is sending a heart in a Facebook message being unfaithful? Or is it micro-cheating?”

Connecting through social media has never been easier and with the wide range of dating apps available today, the digital age has had a deep and lasting impact on dating and meeting people. 

Micro-cheating is more about being secretive about your online presence than liking someone’s post, although Graff does mention that liking and commenting could affect your relationship. 

For example, putting someone in your phone under a different name or hiding your communication with someone via social media may fall under micro-cheating. 

“Secrecy or covert communications are often, but not always, a sign of micro-cheating,” Graff told <a href="http://www.telegraph.co.uk/news/2018/01/15/micro-cheating-social-media-tearing-couples-apart-scientists/">The Telegraph</a>. 

Critics of the term, however, are not convinced. Twitter has sparked much debate on the subject, with some going as far as to say that being wary of who you connect with online constitutes a controlling relationship rather than secretive flirting.

Do you work better alone or in a group? There has been much debate surrounding whether collaboration actually yields better results, or just ends up being too many cooks in the kitchen.

But now, a new study has found that people answer quiz puzzles and questions more accurately in groups than on by themselves.

The study was conducted by researchers from the <a href="https://www.ucl.ac.uk/">University of College of London</a> and published in the journal Nature Human Behavior. 

The study contradicts the popular and scientifically backed theory that solving problems in a group setting doesn’t effectively find a solution as it can cause “herd think.”

“Many previous studies on the wisdom of crowds found that discussing with others could hinder collective wisdom because social influence leads to imitation and the power of the crowd vanishes,” said Dr. Joaquin Nvajas, lead author of the study. 

The research found that working together was actually more effective for problem-solving as group members share ideas, reasoning, and arguments when coming to a common solution. 

The team tested the general knowledge of 5,180 people, including questions ranging from the height of the Eiffel Tower to the number of elevators in the Empire State Building.

For the first part of the study, individuals were asked to answer questions on their own and had a 20 second time limit. Next, people were put into groups of five and were given 1 minute to answer four out of eight questions. 

When placed in groups, incorrect answers were reduced by almost half, 49.2 percent. Errors and wrong answers were fixed or at least closer to the correct answer when people worked together. 

The results show that <a href="https://www.earth.com/news/study-groupthink-actually-productive/">herd-think</a> and crowd mentality may not be as detrimental to problem-solving as previously thought. 

“Our results are in contrast to an extensive literature on herding and dysfunctional group behavior, which exhorts us to remain as independent as possible,” the authors wrote. “Instead, our findings are consistent with research in collaborative learning showing that 'think–pair– share' strategies and peer discussion can increase the understanding of conceptual problems.

When the Spanish conquistador Hernando Cortés landed in Mexico in 1519, the native population was about 25 million. Just 100 years later, the population had plunged to around 1 million, as a result of war and a number of epidemics.

In 1576, the outbreak of a mysterious disease is estimated to have killed between 7 and 17 million of the Aztec people, effectively destroying the Aztec empire. It was known to the locals as cocoliztli, and presented as red spots on the skin, as well as vomiting and bleeding from various orifices. This epidemic was one of the most deadly in human history, and now scientists may know what caused it.

In a study from the <a href="http://www.shh.mpg.de/en">Max Planck Institute for the Science of Human History</a> (MPI-SHH), researchers analyzed ancient teeth and found that the collapse of the Aztec civilization may have been due to an epidemic of salmonella – the food poisoning bacteria. Scientists looked at samples of pulp from inside the teeth of skeletons found in an untouched cemetery in Oaxaca, Mexico. Ten of the skeletons whose burials were dated after the Spanish conquest tested positive for salmonella, but none of the five skeletons buried before the conquest tested positive for the bacteria.

These findings make salmonella “a strong candidate” for the cause of the devastating epidemic that wiped out the Aztecs and other civilizations like the Mixtecs. It did so by leading to a condition called enteric fever, which is still the cause of millions of deaths globally. Spread by poor sanitation – and likely brought by the European travelers – this disease causes high fevers, <a href="https://www.earth.com/news/birds-dehydration-climate-change/">dehydration</a>, and gastrointestinal complications.

This study is the first example of scientists finding molecular evidence of this bacterium using ancient material from the New World. 

“A key result of this study is that we were successful in recovering information about a microbial infection that was circulating in this population, and we did not need to specify a particular target in advance,” says Alexander Herbig of the MPI-SHH and co-author of the study. 

Not only have we learned more about the history of the people and civilizations that came before us, but this result was achieved through advancing science and technology in our current world.

New York City Mayor Bill de Blasio has announced new goals for reducing greenhouse gas emissions and making New York a global leader in the battle against <a href="https://www.earth.com/news/climate-change-removed-websites/">climate change.</a>

According to the mayor, New York City will divest five billion dollars of city pension funds from the fossil fuel industry.

“This city is standing up and saying, ‘We’re going to take our own actions to protect our own people,’” the mayor said.

De Blasio also discussed a city lawsuit against five oil companies: Chevron, BP, ConocoPhillips, ExxonMobil, and Royal Dutch Shell.

The who's who of “big oil” are accused of willingly hiding the fact that fossil fuels are a major contributor of global warming and keeping any scientific findings away from the public. 

The lawsuit, which has been compared to similar lawsuits brought against tobacco companies years ago will take time, and there is concern that it is a largely futile endeavor.

The oil companies themselves say that the lawsuit won’t do anything actually to help solve the climate change crisis, but those in favor are more hopeful that it will strike at the heart of the fossil fuel industry. 

New York City is looking for reparations to the tune of billions meant to repay the money spent on damages caused by climate change, such as the flooding from Hurricane Sandy. 

Time will tell if de Blasio will follow through on his plans for combating climate change and if the lawsuits against oil companies will be successful. If the oil companies are asked to shell out money, it could create new, unprecedented demands for renewable energies in the United States.

A new study from the UK shows just how influential junk food commercials are on teenagers. 

Teens who regularly watch more than three hours of commercial TV a day are more likely to eat hundreds more junk food snacks per year than those who don’t watch TV or watch TV without commercial breaks. 

The report was conducted by <a href="https://www.cancerresearchuk.org/">Cancer Research UK</a> and is the largest study of its kind examining the impact of commercial <a href="https://www.earth.com/news/watching-tv-diminished-mobility/">TV</a> on diet and food preferences. 

The researchers based their results on a <a href="https://yougov.co.uk/">YouGov </a>survey that included responses from 3,348 people in the UK ages 11 through 19. 

Among those surveyed, the teens who regularly streamed TV with commercials were 139 percent more likely drink sugary carbonated beverages and 65 percent more likely to eat pre-packaged, frozen dinners than those who don’t watch as much TV. 

The researchers also found that watching TV without commercials had no impact on junk food preferences. 

These results are especially concerning because high-calorie junk food increases the risk of obesity, and obesity in the UK is the second most preventable cause of cancer after smoking. 

“This is the strongest evidence yet that junk food adverts could increase how much teens choose to eat,” said Dr.  Jyotsna Vohra, a lead author on the study. “We're not claiming that every teenager who watches commercial TV will gorge on junk food, but this research suggests there is a strong association between advertisements and eating habits.” 

One of the problems, according to Dr. Vohra, is the lack of regulations on TV junk food marketing. Vohra suggests limiting exposure to junk food commercials and removing them from programming with a largely younger demographic. 

Limiting exposure could help teenagers who would normally binge on snacks while watching TV cut back on calories and help reduce the risk of obesity. 

“Obese children are five times more likely to remain obese as adults which can increase their risk of cancer later in life,” said Linda Bauld, Cancer Research UK's prevention expert. “The food industry will continue to push their products into the minds of teens if they're allowed to do so. The Government needs to work with Ofcom [the UK’s Office of Communications] to protect the health of the next generation.”

The One-Straw Revolution isn’t, at face value, a book about what most would consider environmentalism.  However, The One-Straw Revolution through example shows an almost ideal way of living with the land in an environmentally friendly way. 

If you focus on yourself as an individual within a greater community (not only a community of people but of plants, fungi, other animals, etc.) you naturally tend towards an environmentally friendly way of living.  For example, The One-Straw Revolution talks about ‘do nothing’ farming, and initially it seems like this way of farming is for the ease of the farmer.  Do nothing agriculture may be easier than traditional forms of farming but it’s much more than that.  Do nothing agriculture is admitting that natural systems are closer to harmony and balance within a greater ecological community than an agriculture system of a human unilaterally exerting ‘control’.  This way of thinking and living is the epitome of the high tech ways of living we embrace now and more so are developing.  Crops with a host of pesticides, herbicides, artificial fertilizers and automated watering systems now have even their genes edited by human control.

I say all of this to define at the outset of this article what ‘living small’ means to me. Someone can live on 10,000 acres of land and be living smaller than someone living in a 400 square foot apartment with no lawn.  I define living small as a matter of which resources we use but also how we use them and the extent to which others may also use.  

For instance, living on 10,000 acres of undeveloped land allows use by many other organisms than living in a sterile apartment treated for any sort of ‘pests’.  Likewise, ‘do nothing’ farming allows for more use by other organisms of the same land than does traditional or high tech agriculture.  Doing anything always incurs cost.  If you eat, it costs something to the environment; that cost is paid back through waste which may nourish other organisms and inevitably your own body which through decomposition again becomes parts of other organisms.  Doing anything risks damaging the environment or other organisms, the key to less damage is less doing.  This idea is counter intuitive to many westerners, even or perhaps especially those exposed to the hyperactive Teddy Roosevelt school of doing and taking the mistakes as they come.  There have been many mistakes in mainstream conservation when doing nothing was better than doing something.  Examples that spring immediately to mind are Mariana Crows and Kaibab Deer.  

Kaibab deer of the Kaibab Plateau of Arizona are a unique population, wishing for them to be protected the U.S. government initiated an intense management and <a href="https://www.earth.com/news/california-water-conservation-benefits/">conservation</a> plan.  Predators of the deer were killed off and hunting of the deer themselves was outlawed.  For a short time the deer population boomed.  After the boom in deer numbers came a hard crash.  Quickly deer numbers grew too large to be supported by the plant life available and the deer in turn starved in masses.  Predators it turns out can in their own way help a prey species or at least keep them from the slow agonizing death of starvation.

The Hawaiian Crow is another example of hubris on the part of those who would protect a wild animal.  Crows were endangered and to learn more and hopefully implement a conservation plan, monitoring ensued.  Cameras were set up at crow nests to record the bird’s behavior on public land.  There was a local rancher who refused to allow research on her land saying the bird is best left alone.  In the end, the rancher was right.  The cameras scared the crows, causing many to abandon their nests due to the noise of the now antiquated recording devices.  The crows left alone on the ranch fared much better in the long run, being more successful in rearing young.  

I believe the two examples along with others can be applied not only to science or environmentalism but to our daily lives.  The more we do, the more unintended consequences we incur.  Part of the problem is thinking deeply about what doing more or less, living bigger or smaller means.  Doing more for yourself and requiring less from businesses, the government or other organizations means doing less.  Living on a hundred acres that you cultivate is living smaller than living in a hundred square foot apartment where you buy all your food from a grocery store.  Likewise, when you do purchase, purchasing truly local items can help, buying not from a local business but a local producer or grower for instance.  

As a rule of thumb, the simpler your lifestyle, the less extravagant and the more you take personal responsibility for all you use, the better.  It’s about being humble and admitting you are part of a greater community as much as it is about self-sufficiency.  Self-sufficiency is really an illusion, you always depend on others: other plants, fungi, animals, people, bacteria, the sun, etc.  Living simply means working with the seasons, with the environment and surrendering a little, not unilaterally imposing your will on everything around you.  It’s about simple observing and just being a part of a whole instead of consuming the whole to merely feed a part.

According to a survey from the marketing research group <a href="http://www.comresglobal.com/">ComRes</a>, many people who are not <a href="https://www.earth.com/news/religious-beliefs-linked-upbringing/">religious</a> still pray during difficult times. The study has revealed that one in four atheists and agnostics pray on a regular basis in times of personal crisis.

Atheists and agnostics reported that the most common reason for them to pray is during a tragedy, but 25 percent of these individuals admitted to also praying for comfort or simply out of loneliness.

According to the online poll, which was sponsored by the Christian aid agency <a href="https://www.tearfund.org/">Tearfund</a>, over half of the adults in the UK pray on a regular basis. However, only about one third of participants said that they pray in a church.

A 2014 <a href="https://www.google.com/amp/www.pewresearch.org/fact-tank/2016/05/04/5-facts-about-prayer/%3famp=1">Pew Research Center</a> survey found similar results, reporting that 55 percent of Americans pray on a daily basis. Even of those respondents who were religiously unaffiliated, 20 percent said that they prayed daily. Most of the American participants said that they relied on prayer when they were making major decisions in their lives.

In the UK survey, individuals were asked what they pray about. Over 70 percent of the participants reported praying for family members, while 40 percent mentioned their friends to God. 

In addition, 40 percent of the UK respondents asked for healing through prayer. Around one-third of the participants said they pray just before going to sleep or first thing in the morning.

A little less than half of the individuals surveyed thought that God actually hears their prayers, while 40 percent of the participants said they believe that prayer can change the world.

Tearfund representative Ruth Valerio told <a href="https://www.theguardian.com/uk">The Guardian</a>, “While it is often easier to pray for issues closer to home, we want to encourage people to continue to engage with global issues and pray for an end to extreme poverty.”

Plague, also known as the Black Death or the Bubonic Plague, is caused by the bacterium Yersinia pestis. There have been several major pandemics and outbreaks of the plague, including the Great Plague of 1665 when reportedly 7,000 people a week died in London. 

The Black Death which hit medieval Europe in 1347 saw such rapid mortality rates, sometimes half of a city’s entire population, that mass graves became a necessary way to bury the dead. 

The impacts of the plague are well known, and when determining the cause of the outbreaks, many scientists blamed rats, which carried fleas infected with Yersinia pestis. This theory is so widely held that most people would say with certainty that <a href="https://www.earth.com/news/rats-major-cities-monitored/">rats</a> caused the spread of the Black Death. 

However, a new study conducted by researchers from the <a href="http://www.uio.no/english/">University of Oslo, Norway</a>, found that rats may have been unfairly blamed all these years, and that infection was likely spread by human fleas and lice. 

Many people were infected with fleas and lice, and thanks to close living quarters and sharing beds, the black death could have quickly spread from human to human. 

Frequent bathing was also not as common an activity during the middle ages, at least not by today’s current standards of hygiene. 

For the study, the researchers ran models using both rats and human fleas and lice to see if rates of infection matched the mortality patterns from nine different European plague outbreaks during the Second Pandemic. 

The rat models, even supposing there was one rat for every human at the time, didn’t come close to matching the real spread of infection during the plague. Instead, the human-parasite model came much closer to matching the mortality records of the time. 

This means that as humans were infected with the plague, their fleas and lice would spread to other humans close by, and with them the disease, rather than rats spreading the disease. 

The study could help inform plague research and shed light on just how the plague spread. The Great Plague and Black Death wiped out millions in Europe and with the plague still causing outbreaks today, it’s important to better understand how it spread and what set it apart from plague today. 

“The plague really transformed human history, so it’s really important to understand how it was spreading and why it was spreading so fast,” Katharine Dean, the study’s lead author, told <a href="https://news.nationalgeographic.com/2018/01/rats-plague-black-death-humans-lice-health-science/">National Geographic. </a>

The <a href="https://www.rand.org/">RAND Corporation</a> is reporting that an increasing amount of disagreement over facts in America has led to political paralysis and a lack of civil engagements to discuss and better resolve issues. The experts say that this phenomenon, known as “Truth Decay,” is characterized by the blurring of <a href="https://www.earth.com/news/battling-climate-change-misinformation/">opinions</a> and facts and by the declining trust in formerly respected sources of factual information.

While this type of shift may have occurred previously in the history of the United States, the Truth Decay over the last two decades is intensified by the ways in which Americans now consume information, such as through cable news and social media. The researchers pointed out that political, economic, and social polarization may also be responsible for worsening the conditions of Truth Decay today.

Michael D. Rich is the president and CEO of the nonprofit RAND Corporation and co-author of the study.

“Although we see some evidence that previous eras also experienced a decline in trust in institutions, this trend seems to be more pronounced now than in the past,” said Rich. “Today we see that lack of trust across many more pillars of society - in government, media and financial institutions - and a far lower absolute level of trust in these institutions than before.”

The study has revealed that Truth Decay has many damaging consequences, such as political paralysis and uncertainty in national policy, which also lead to economic costs. For example, the government shutdown of 2013 lasted 16 days and resulted in a $20 billion loss to the United States economy, according to the researchers.

The research team analyzed past eras in American history when similar periods of Truth Decay took place, focusing on events such as the rapid industrialization and economic inequality during the 1880s and 1890s. The experts found that government transparency backed by policy changes and the renewal of responsible journalism were capable of ending most of these tumultuous times.

The RAND researchers will continue to monitor three trends which are related to Truth Decay, including the shifting balance of opinion and objective reporting in journalism, the decline of public trust in major institutions, and initiatives to improve media literacy in light of “fake news.”

"We urge individuals and organizations to join with us in promoting the need for facts, data and analysis in civic and political discourse - and in American public life,” said Rich. “The challenge posed by Truth Decay is great, but the stakes are too high to permit inaction.”

Life expectancy and mortality rates are improving in the United States, thanks largely in part to decreases in smoking.

However, new research has found that mortality rates are also heavily impacted by a rise in <a href="https://www.earth.com/news/national-junk-food-tax/">obesity</a> over the past several decades, resulting in a reduced rate of improvement in American mortality.

The study was conducted by a trio of researchers from the <a href="https://www.sas.upenn.edu/">University of Pennsylvania</a> and <a href="https://www.bu.edu/">Boston University</a>.

The study examined mortality rates in conjunction with body mass index (BMI) over a person’s lifetime. BMI is a standard measurement of obesity and defines a healthy mass based on both height and weight. 

The researchers found that looking at a person’s lifetime maximum BMI instead of just using a baseline BMI garnered far more accurate results in predicting mortality. 

Data was gathered from the <a href="https://www.cdc.gov/nchs/nhanes/index.htm">National Health and Nutrition Examination Survey</a> from the years 1998 through 1994 and 1999 through 2010, and any mortality files that were linked to the survey. The last survey year used for the study had a group of 25,269 adults ages 40 to 79. 

Results of the analysis showed that mortality was not declining at a fast enough rate to reflect a major shift to non-smoking in the population and this was directly linked to a rise in obesity. 

“We estimated that the impact of rising obesity was about twice as important for mortality trends as the impact of declining smoking,” said Samuel Preston, a member of the research team. “Smoking is such an important variable in mortality analysis, and U.S. mortality is improving faster than it otherwise would because of reductions in smoking, but it's not improving fast enough to offset the effect of obesity."

The results also showed that if obesity rates hadn’t risen, there would be a half percentage point decrease in mortality, and that rising BMI reduced life expectancy by .9 years at age 40. 

Preston and his fellow researchers note that the study highlights the importance of understanding just how mortality rates are impacted by a rise in obesity, and how reversing the rising trend is vital for raising life expectancy in today’s society.

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">
https://youtu.be/Ug657J67iEo?si=w96YjGMsg939LD_3
</div></figure>



Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</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."

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. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.

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



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



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



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



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

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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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