We all know the pull of one more episode. Streaming services make it easy to keep watching, and though it often feels like a guilty pleasure, new research suggests it may not be entirely bad.



A study from the University of Georgia (<a href="https://www.uga.edu" target="_blank" rel="noreferrer noopener">UGA</a>) highlights that binge-watching or marathon reading can actually strengthen how we remember stories. 



These memories may not vanish once the credits roll but instead linger in our minds, shaping imagination and reflection.



<h2 class="wp-block-heading" id="h-binge-watching-strengthens-memory">Binge watching strengthens memory</h2>



The research connects this phenomenon to something called <a href="https://academic.oup.com/edited-volume/34268/chapter-abstract/290548954?redirectedFrom=fulltext" target="_blank" rel="noreferrer noopener">retrospective imaginative involvement</a>, or RII. It refers to how people continue to think about characters and events after finishing a story.



Rather than ending with the last chapter or episode, stories are reconstructed, expanded, and sometimes even altered in imagination.



“Humans are storytelling creatures. One of the functions of narratives is the ability to <a href="https://www.earth.com/news/social-media-use-increases-smoking-vaping-risks-among-youth/">satisfy motivations</a> for things like connecting with other people, feeling autonomous and confident, and even security and safety. Stories have characters that fulfill these roles, and we can satisfy those needs through them,” noted Joshua Baldwin, lead author of the study.



<h2 class="wp-block-heading" id="h-memory-and-imagination">Memory and imagination</h2>



The study shows that people who binge-watch are more likely to engage with stories later, carrying them into daydreams. 



Consecutive viewing appears to help audiences create richer mental models of characters and worlds, which makes these stories more accessible in <a href="https://www.earth.com/news/emotions-shape-what-goes-viral-on-social-media/">memory</a>.



By consuming content in longer stretches, viewers weave tighter connections across episodes and character arcs, allowing subtle details to resonate more clearly.



This means binging may support stronger recall in the short term, even if some details fade over time. 



More importantly, it keeps the emotional and thematic essence alive, which is what fuels imagination and encourages people to revisit stories in new, creative ways.



<h2 class="wp-block-heading" id="h-why-people-binge-watch">Why people binge watch</h2>



The reason behind a person's binge-watching habits also matters. Some are drawn to stories to escape stress, while others seek to expand their sense of self through new perspectives.



The Temporarily Expanding Boundaries of the Self (<a href="https://academic.oup.com/edited-volume/34268/chapter-abstract/290539200?redirectedFrom=fulltext">TE</a><a href="https://academic.oup.com/edited-volume/34268/chapter-abstract/290539200" target="_blank" rel="noreferrer noopener">B</a><a href="https://academic.oup.com/edited-volume/34268/chapter-abstract/290539200?redirectedFrom=fulltext" target="_blank" rel="noreferrer noopener">OTS</a>) model suggests narratives allow people to step outside daily limits and experience autonomy, competence, and connection in imagined worlds.



Escapism-driven viewing, on the other hand, gives relief by pushing aside everyday stress. 



The study found both motivations can lead to retrospective imagination, though expansion motives appear more powerful in creating long-lasting engagement.



<h2 class="wp-block-heading" id="h-enjoyment-versus-appreciation">Enjoyment versus appreciation</h2>



Not all stories affect memory the same way. Lighter tales that are fun and easy to watch often spark simple recollections. 



By contrast, appreciated stories (those that feel deep, moving, or even bittersweet) encourage people to reimagine, expand, and reshape them.



These more reflective narratives are especially likely to trigger dynamic forms of imagination, such as changing events or exploring hidden backstories.



<h2 class="wp-block-heading" id="h-stress-and-leisure-time">Stress and leisure time</h2>



Stress does not influence story recall in a simple way. When stress is low or moderate, imagination can act as a relief, giving people a way to unwind and mentally process experiences. In these cases, stories serve as a calming outlet.



However, when stress levels rise too high, the brain becomes overloaded, leaving fewer mental resources available for remembering or reflecting on narratives. 



Instead of nurturing imagination, the mind directs energy toward coping with immediate pressures.



Leisure time changes the picture. When people have free, relaxed moments, their minds are more open to revisiting favorite stories. 



These quiet breaks - during a walk, while chatting, or simply reflecting - create mental space for narratives to return, grow, and shape daydreams.



<h2 class="wp-block-heading" id="h-binge-watching-can-support-coping">Binge watching can support coping</h2>



Binge-watching has often been criticized for harming sleep and well-being. But this research suggests the picture is more nuanced. 



For some, it builds mental models that last well beyond the show itself. These memories and imagined extensions may even help people cope with challenges, making stories an ongoing psychological resource.



“People who have that habit of binge-watching shows often aren’t doing it passively but are actually actively thinking about it afterwards. They’re very much wanting to engage with stories, even when they’re not around to watch shows,” Baldwin explained.



<h2 class="wp-block-heading" id="h-stories-live-on-beyond-the-screen">Stories live on beyond the screen</h2>



Most people think bingeing means wasting hours in front of a screen. But the study shows it can be much more than that. 



When you get lost in a story, the characters and emotions often tag along even after you stop watching. Sometimes they reappear in <a href="https://www.earth.com/news/most-dogs-binge-watch-television-everyday/">daydreams</a>, other times in quiet reflections when your mind drifts.



This habit doesn’t just strengthen memory. It can stir creativity, spark imagination, and even help people make sense of their own lives. 



Stories can offer comfort, connection, or a fresh perspective - things we all need from time to time. That’s why they rarely end with the credits. Instead, they linger in our thoughts, shaping how we dream, reflect, and connect with the world.



The study is published in the journal <a href="https://www.sciencedirect.com/science/article/pii/S0001691825004147?via%3Dihub" target="_blank" rel="noreferrer noopener">Acta Psychologica</a>.

Why binge-watching TV shows may actually be good for your mind

We all know the pull of one more episode. Streaming services make it easy to keep watching, and though it often feels like a guilty pleasure, new research suggests it may not be entirely bad. A study from the University of Georgia (UGA) highlights that binge-watching or marathon reading can actually strengthen how we remember stories.

A recent study reveals that marriage may actually lower a person's risk of getting dementia, while widowers and single adults are at a higher risk of developing the chronic disorder.

Researchers collected data from 15 relevant studies published through 2016. The experts analyzed the reports, which were based on over 800,000 participants from Europe, North and South America, and Asia, to determine whether there was a link between marital status and dementia risk.


After accounting for age and gender, the study showed that lifelong single adults were 42 percent more likely to develop <a href="https://www.earth.com/news/dementia-expensive-families/">dementia</a>. The researchers pointed out that this single group has poorer overall health, which may help to explain the heightened risk.

However, studies based on single people born after 1927 showed that dementia risk was just 24 percent higher. This indicated that the health risk lessened across single adults over time, but the researchers have not identified the reason for this.

Widowers were found to be 20 percent more prone to dementia than married people, and the experts believe this may be partially attributed to the heightened stress levels caused by bereavement. These stress levels are linked to impaired nerve signaling and cognitive functioning.

According to the researchers, the connection between lower dementia risk and marriage strengthened as the study became more in depth. The team believes that married couples engage in healthier lifestyles, such as eating well and exercising more, which are associated with a lower risk of dementia.

While the findings of the study suggest that there are factors which reduce the chance that a person will develop dementia, the researchers pointed out that dementia is still not easily prevented.

"Therefore, ways of destigmatising dementia and producing dementia-friendly communities more accepting and embracing of the kinds of disruptions that dementia can produce should progress alongside biomedical and public health programs," said the study authors.

The research is published online in the <a href="http://jnnp.bmj.com/">Journal of Neurology Neurosurgery &amp; Psychiatry</a>.

Around the time that urban societies were developing in Egypt and Mesopotamia between 5,300 and 3,300 years ago, the Indus Civilization was also evolving. Scientists have long believed that the settlements of this era sprung up along the banks of a thriving river, but new evidence shows that a major Himalayan river central to the Indus Civilization was no longer active.

The Ghaggar-Hakra River in northwest <a href="https://www.earth.com/image/smoke-fog-northern-india/">India</a> and Pakistan is believed to have dried up due to changes in the climate or shifting tectonic plates. But, prior to this study, scientists did not know exactly when the river ceased. It was assumed that the Indus settlements depended on the river and developed around it.

However, a research team from <a href="https://www.imperial.ac.uk/">Imperial College London</a> and the <a href="https://www.iitk.ac.in/">Indian Institute of Technology Kanpur</a> has now provided surprising evidence that the Ghaggar-Hakra was no longer flowing at the time the settlements of the Indus Civilization emerged. The findings of the study suggest that ancient urban societies did not depend exclusively on an active, flowing river system to flourish.

"The findings challenge our current understanding of how urbanization in many ancient civilizations began and grew in relation to natural resources,” said lead author Professor Sanjeev Gupta. “Contrary to current belief, it was the departure of a large river, rather than its arrival, that triggered the growth of Indus urban centers."

The researchers discovered that a major Himalayan river, the Sutlej River, once flowed in the tracks of the Ghaggar-Hakra River, but abruptly changed course about eight thousand years ago. By the time the Indus people settled into the region, there was only an abandoned large river valley.

The large impression in the ground left behind from the the Sutlej River collected water seasonally from monsoons, providing the Indus settlements with a temporary source of water.

"We now know that, given the right conditions, valleys that have lost their rivers can still serve as a water source,” said study co-author Rajiv Sinha. “The civilization would also not have been threatened by the risk of devastating floods that living next to a big river brings."

Since most previous research has been focused on the link between rivers drying up and the abandonment of ancient urban centers, the team believes this study may encourage archaeologists to take a new look at the development of settlements in early civilizations. The study is published in the journal <a href="http://www.nature.com/ncomms/">Nature Communications</a>.

An unprecedented study by researchers at <a href="http://www.cumc.columbia.edu/">Columbia University Medical Center</a> (CUMC) has investigated the nature of deaths from opioid overdoses. The study revealed that 60 percent of individuals who died as a result of opioid overdose were previously diagnosed with chronic pain, while a great number of fatalities also occurred in individuals who had psychiatric disorders.

The <a href="https://www.cdc.gov/">Center for Disease Control</a> reports that the number of opioid-related deaths quadrupled between 1999 and 2015, jumping from 8,048 to 33,091.

The research team analyzed the clinical diagnoses and medication prescriptions of over 13,000 adults who died of an opioid overdose between 2001 and 2007. Over 50 percent of these individuals had been diagnosed with chronic pain, while many others had been diagnosed with depression and anxiety. 

"The frequent occurrence of treated chronic pain and mental health conditions among overdose decedents underscores the importance of offering substance use treatment services in clinics that treat patients with chronic pain and mental health problems,” said study lead author Dr. Mark Olfson. “Such a strategy might increase early clinical intervention in patients who are at high risk for fatal opioid overdose.”

While nearly a third of those who died had been diagnosed with a drug use disorder in the year prior to death, less than one in twenty had been diagnosed with an <a href="https://www.earth.com/news/fish-fight-opioid-addiction/">opioid</a> use disorder in the month before death.

"Because clinical diagnoses generally indicate treatment, this service pattern suggests that dropout from drug treatment is common before fatal opioid overdose,” said Dr. Olfson. “Improving treatment retention with contingency management or other effective behavioral interventions might help lower the risk of fatal overdose in these patients.”

More than half of the individuals who overdosed had filled prescriptions for opioids or benzodiazepines in the year before death, and many had filled prescriptions for both types of medications. 

"This medication combination is known to increase the risk of respiratory depression, which is the unusually slow and shallow breathing that is the primary cause of death in most fatal opioid overdoses," said Dr. Olfson. "In the years since, there has been an increase in the proportion of US overdose deaths involving benzodiazepines and opioids." The authors urged providers to restrict the combination, in the lowest possible dose and duration, to those patients for whom alternative strategies have proven inadequate.

The study, “Service Use Preceding Opioid-Related Fatality,” is published in the <a href="https://ajp.psychiatryonline.org/">American Journal of Psychiatry</a>.

As we enter the colder months in the Northern hemisphere, we’re beginning to see an influx of people sniffling, coughing, and sneezing all around us. The common cold usually makes its first appearance around this time, spreading like wildfire through offices, schools, and homes. But why is it that we seem to catch this same virus every single year? Why hasn’t our body developed an immunity to it yet? 

These are questions that new research published in <a href="https://www.nature.com/ncomms/">Nature Communications</a> might just answer. Professor Pierre Talbot from <a href="http://www.inrs.ca/english/homepage">Institut National de la Recherche Scientifique</a> (INRS) in Canada has been studying coronaviruses – which include the common cold – for many years. These viruses come in a wide variety, and include other infections such as neurological diseases. In this study, Talbot and his colleagues attempted to find out why coronaviruses are able to adapt and evolve so effectively while evading a host’s immune system.

In appearance, coronaviruses look like tiny, spiky spheres. Now, the researchers believe that these spikes play a role in the virus’s ability to adapt to new environments. The spikes are made up of S proteins (the S stands for spike, of course), which allow the virus to attach itself to host cells. Specifically, the spike’s receptor binding domain (RBD) initiates the interaction between a cell and the virus. However, these RBDs are also targets for antibodies in the host’s immune system that are seeking to neutralize the virus.

So for coronaviruses to infect a host cell, it needs an exposed RBD. But that same RBD is a target for antibodies, so in order for the virus to be effective, the RBD needs to be masked. Talbot and his colleagues figured out that the coronavirus does this by having an RBD that is made up of three parts that vary significantly between strains. Due to this variation, antibodies are unable to detect a new strain, but the RBD still retains – and in some cases improves – its affinity for the target cell. Furthermore, the RBDs can alternate between visible and masked states.

The research team analyzed the RBD’s structure up close, finding three long loops that attach to the host cell protein. Previous analyses of these viruses dating back roughly a half-century have found that these loops are essentially the only thing that varies from one coronavirus strain to the next.

Through this research, we now have a better understanding of why the <a href="https://www.earth.com/news/fruit-flies-teach-humans-common-cold/">common cold</a> is so persistent. Although there is a lot more work to be done, it’s possible that research such as this could lead to a welcome reduction in wintertime sniffling, coughing, and sneezing.

Why can’t humans develop immunity against the common cold?

Carbon-based organic semiconductors could soon play a major role in electronics and solar energy conversion.

Semiconductors, usually made of silicon, are essential to all modern electronics and can be found in everything from <a href="https://www.earth.com/news/rational-choices-smartphones-computers/">smartphones</a> to televisions. 

Semiconductors are somewhere between a conductor and an insulator. They don’t work as a true insulator like glass, nor do they have the same conductive strengths as metal, hence the name semi. 

Doping is required to increase the conductive properties of a semiconductor. Doping is a process where chemicals or impurities are added to the semiconductor which then changes the electrical behavior of the semiconductor.  

A team of researchers from <a href="https://www.princeton.edu/">Princeton University</a>, the <a href="http://www.gatech.edu/">Georgia Institute of Technology</a> and <a href="https://www.hu-berlin.de/en/">Humboldt University in Berlin</a> have found a way to increase the conductivity of organic semiconductors with doping. 

“Organic semiconductors are ideal materials for the fabrication of mechanically flexible devices with energy-saving low-temperature processes,” said Xin Lin, one of the researchers. “One of their major disadvantages has been their relatively poor electrical conductivity.  In some applications, this can lead to difficulties and inefficient devices. We are working on new ways to improve the electrical properties of these organic semiconductors.” 

For the study, the researchers developed a new type of dopant which drastically improves the conductivity of organic semiconductors. 

The dopant is a ruthenium-containing compound and a reducing agent. It adds electrons to the semiconductor. The results show that the ruthenium compound dopant increases the conductivity of organic semiconductors nearly one million times its original value. 

For the compound to work with organic semiconductors, the research team had to figure out how to break apart the ruthenium.  The ruthenium compound is a dimer, and it contains two identical molecules which are connected by a chemical bond. 

The researchers examined different possibilities for breaking the compound's molecules apart in order for it to work as a dopant, eventually finding that when exposed to ultraviolet light the dopant increased the conductive properties by almost 100,000 times. 

Even when the UV light was turned off, the dopant still worked with the organic semiconductors. 

“Once the light is turned off, you might expect the reverse reaction to occur and the increased conductivity to disappear. However, that is not the case,” said Seth Marder, one of the leaders in the development of the new dopant. “The light activates the system more, which leads to more light production and ore activation until the system is fully activated.” 

This discovery is a breakthrough for semiconductors and increasing the conductivity of organic semiconductors.

Cinnamon could be a new key ingredient in your diet, as a new study has revealed that a compound in cinnamon could help fight obesity and hyperglycemia. 

Cinnamaldehyde is a naturally occurring oil found in cinnamon that has been proven to help counter obesity and hypoglycemia in mice, and researchers from the<a href="https://umich.edu/"> University of Michigan</a> wanted to see if humans could reap similar benefits.

The new study was published in the journal Metabolism. 

The researchers found that cinnamaldehyde activates metabolic responses and aids in thermogenesis. Thermogenesis is an essential metabolic process in humans where the energy used to burn calories produces heat. 

Cinnamaldehyde gives fat cells an added boost to burn energy. 

For the study, the researchers used adipocytes (fat cells) from both mice and humans. First, fat cells from mice were treated with cinnamaldehyde and the researchers observed how the compound affected the cells. 

Then the researchers used adipose stem cells from human volunteers to see if the results of the mice testing could be duplicated in human fat cells. 

The cinnamaldehyde worked similarly in humans, boosting <a href="https://www.earth.com/news/harder-burn-off-belly-fat/">metabolism</a> by increasing proteins that are helpful to thermogenesis. 

The results are promising, showing that cinnamon, even in small amounts used in baking and seasoning, could help counter weight gain and even help with treating diabetes. 

“Cinnamon has been part of our diets for thousands of years, and people generally enjoy it,” Jun Wu, a co-author of the study, told <a href="https://www.usatoday.com/story/news/nation-now/2017/11/25/cinnamon-may-help-attack-fat-fight-obesity-study-finds/894486001/">USA Today</a>. “So if it can protect against obesity, too, it may offer an approach to metabolic health that is easier for patients to adhere to.” 

The study shows that cinnamaldehyde activates thermogenesis in both mice and humans, but further testing will need to be done before your doctor suggests cinnamon as a new way to lose weight.

California mayoral candidate Kevin Saunders is pushing for the legalization of psychedelic mushrooms. Saunders, who is running for mayor in the town of Marina, hopes to give voters in California the option of legalizing magic mushrooms on the 2018 ballot.

Saunders believes that psychedelic <a href="https://www.earth.com/news/magic-mushrooms-depression-brain/">mushrooms</a> may help adults work through the stress of today's world.

“The world is really hurting and everybody is at a loss about what’s going on right now with Trump, Brexit, the refugee crisis and everything else,” said Saunders.

The former cannabis advocate stands behind the transformative power of psilocybin, saying that, “It could allow people to figure out what to do and could revolutionize the way we treat those with depression, addiction and cluster headaches.”

Psilocybin, the hallucinogenic compound found in magic mushrooms, is classified as a Schedule I drug. However, the use psilocybin has been approved for medical trials in dozens of states.

In fact, the concept of having magic mushrooms legalized may not be as far-fetched as it seems, as clinical trials are underway in both the United States and Europe to test the potential of psilocybin in treating alcoholism, tobacco addiction, severe anxiety, and treatment-resistant depression.

Saunders told <a href="https://www.theguardian.com/uk">The Guardian</a> that magic mushrooms helped him recover from a “debilitating five-year heroin addiction” at age 32. He explained,“I got to the root of why I made a conscious decision to become a heroin addict; I’ve been clean almost 15 years.”

Researchers have also demonstrated that psilocybin is safer than other drugs, including alcohol. The 2017 <a href="https://www.globaldrugsurvey.com/">Global Drug Survey</a>, a comprehensive poll that investigates the drug use of 120,000 people in 50 countries, found that 90 percent less patients sought emergency medical treatment for psilocybin compared to alcohol.

Regardless, the U.S. Justice Department's <a href="https://www.justice.gov/archive/ndic/pubs6/6038/#risks">National Drug Intelligence Center</a> compares psilocybin to heroin and LSD. The organization reports, “The psychological consequences of psilocybin use include hallucinations and an inability to discern fantasy from reality. Panic reactions and psychosis also may occur, particularly if a user ingests a large dose.”

In August, Saunders filed paperwork with the State Attorney General's office to let voters in California decide whether psilocybin will be legalized in 2018. He needs 365,880 signatures to get his <a href="https://oag.ca.gov/system/files/initiatives/pdfs/17-0024%20%28Legalize%20Psilocybin%29_0.pdf">California Psilocybin Legalization Initiative</a> on the ballot.

Saunders told <a href="http://www.sacbee.com/">The Sacramento Bee</a> that the legalization of psilocybin is "a natural step after voters’ legalization of pot." 

The <a href="https://www.opsbuzz.com/">Oregon Psilocybin Society</a> has started its own initiative to raise awareness about the safety and benefits of controlled psilocybin, and the organization aims to get psilocybin on Oregon’s statewide ballot in 2020.

New research that is being presented at the annual meeting of the <a href="http://www.rsna.org/">Radiological Society of North America</a> (RSNA) reveals that young football players with a history of concussion or subconcussive impacts experience brain changes after one season of play. 

The studies, conducted at <a href="http://www.utsouthwestern.edu/">UT Southwestern Medical Center</a> in Dallas and <a href="http://admissions.wfu.edu/">Wake Forest University</a>, investigated the brain's default mode network (DMN) to observe how playing football affects youths’ brain health.


The DMN is a network of interacting <a href="https://www.earth.com/news/stress-risky-decision-making/">brain</a> regions that is active during wakeful rest. Changes in the DMN are associated with mental disorders, and decreased connectivity within the network is associated with traumatic brain injury.

"The DMN exists in the deep gray matter areas of the brain," explained study co-author Elizabeth M. Davenport. "It includes structures that activate when we are awake and engaging in introspection or processing emotions, which are activities that are important for brain health."

The research team set out to identify the outcome of numerous subconcussive impacts on the DMN. For this study, they examined youth football players with no history of concussion.

"Over a season of football, players are exposed to numerous head impacts. The vast majority of these do not result in concussion," said co-author Gowtham Krishnan Murugesan. "This work adds to a growing body of literature indicating that subconcussive head impacts can have an effect on the brain. This is a highly understudied area at the youth and high school level."

26 youth football players between the ages of 9 and 13 were equipped with the Head Impact Telemetry System (HITS) for an entire football season. These helmets contain sensors that measure the magnitude, location, and direction of impacts to the head. 

For each player, impact data from the helmets was used to calculate a risk of concussion exposure. The results of the study showed an increasing functional change in the DMN with consistent exposure to head impacts.

"The brains of these youth and adolescent athletes are undergoing rapid maturation in this age range. This study demonstrates that playing a season of contact sports at the youth level can produce neuroimaging brain changes, particularly for the DMN," said Murugesan.

In the second study, 20 high school football players wore the HITS helmets throughout a season. Five of the players had experienced at least one concussion, while the other 15 players had no history of concussion.

After the season, the five players with a history of concussion had substantially lower connectivity in the DMN. The players with no history of concussion typically showed an increase in DMN connectivity.

"The brain's default mode network changes differently as a result of previous concussion," said Dr. Davenport. "Previous concussion seems to prime the brain for additional changes. Concussion history may be affecting the brain's ability to compensate for subconcussive impacts."

New research is showing that xenophobia, or fear of other groups, strongly impacted the outcome of the Brexit vote. The study has revealed that British citizens who felt immigrants were a threat to their way of life were more likely to vote for the <a href="https://www.earth.com/news/brexit-impact-uk-food-agriculture/">United Kingdom</a> to withdraw from the European Union.

Last year, 52 percent of British citizens voted in favor of Brexit. Some experts attributed this surprising outcome to the age, gender, or education of the voters, while others speculated that an agenda known as the “Leave campaign” may have generated a fear of foreigners.

A team of researchers led by Dr. Agnieszka Golec de Zavala at the <a href="http://www.london.ac.uk/">University of London</a> set out to examine the influence that xenophobia may have had on voting behavior. The experts found that feelings of fear of other groups did, in fact, have a noticeable impact on the overall decision of voters.

The researchers next wanted to determine which groups of people feel threatened by immigrants coming into the UK. The team identified three groups. 

First are the authoritarians, who fear disruption of the traditional status quo. Next are people high in social dominance orientation, who compete with immigrants for their group's dominance. The third group is made up of narcissists, who believe the UK is entitled to privileged treatment. The narcissists are concerned that the value of the UK is not acknowledged by other countries. 

Furthermore, the researchers found that people who were simply proud to be British or valued their British identity were not more likely to have xenophobic attitudes or vote for Brexit.

Dr. Golec de Zavala explained that this study pinpoints collective narcissism as a new factor that needs to be considered when predicting political outcomes. 

"From Brexit, Trump and support for Vladimir Putin in Russia to the nationalist, ultra- conservative government in Poland, studies from our and other labs show that collective narcissism systematically predicts prejudice, aggression and a tendency to interpret innocent behaviors as provocation to the national group," she said.

While the study provides evidence that voting was linked to prejudice, the authors point out that this was conducted after Brexit was voted in, and people may have felt more empowered to express their xenophobic attitudes.

The research is published in <a href="https://www.frontiersin.org/journals/psychology">Frontiers in Psychology</a>.

New research from the <a href="https://medicine.yale.edu/">Yale School of Medicine</a> is providing unprecedented insight into what makes humans smarter than other animals. The study has linked the dopamine system in humans to higher intelligence.

The researchers showed that humans have abundant dopamine in the <a href="https://www.earth.com/news/brains-grow-learn-cuts/">brain</a> that guides in thinking and planning. Dopamine is a chemical that plays a central role in reward-motivated behavior. 

The research team established that the progression of the dopamine system in humans is much different than of other species.

For the study, the researchers compared the brains of five macaque monkeys, five chimpanzees and six humans. After analyzing 247 samples of brain tissue, they found substantial differences in dopamine levels.

The inconsistencies were not apparent in some regions of the brain, but differences were very noticeable in the neocortex and the striatum. 

The team found that two enzymes which aid in the production of dopamine were more active in the human brain than in the brains of the other species. The scientists also discovered that three times as many neurons in the human striatum were producing dopamine compared to the ape striatum.

“That caught our attention,” said study co-author Dr. Andre Miguel Sousa.

In addition to reward processing, dopamine plays a role in regulating the brain's executive functions such as memory, attention, and reasoning.

The findings of the study, which are published in the journal <a href="http://www.sciencemag.org/">Science</a>, challenge previous assumptions about the human brain, such as the idea that the neocortex is the only region involved in intelligence. 

The researchers hope the investigation will lead to a better understanding of the brain, as well as help to explain the causes of brain disorders.

The philosopher Rene Descartes once said, “Cogito, ergo sum” – “I think, therefore I am.” He may have been more right than he suspected. A pair of researchers believe that thoughts and feelings don’t rise out of our human consciousness, but from non-conscious structures in the brain.

Dr. David Oakley of <a href="https://www.ucl.ac.uk/">University College London</a> and Dr. Peter Halligan of <a href="https://www.cardiff.ac.uk/">Cardiff University</a> have come to that conclusion after analyzing a number of neuroscientific studies. 

“We suggest that our personal awareness does not create, cause or choose our beliefs, feelings or perceptions. Instead, the contents of consciousness are generated 'behind the scenes' by fast, efficient, non-conscious systems in our brains,” the pair wrote in a column for <a href="https://theconversation.com/what-if-consciousness-is-not-what-drives-the-human-mind-86785">The Conversation</a>.

Basically, they said, human consciousness doesn’t control or generate thoughts and emotions, it just becomes aware of them.

To support their argument, the researchers pointed to the sleep process.

“If this sounds strange, consider how effortlessly we regain consciousness each morning after losing it the night before …” Oakley and Halligan wrote.

They also noted that thoughts and emotions often arise fully formed in people’s minds; they’re not aware of the process of forming them, just as they aren’t aware of the process that pumps the heart or filters blood through the liver. 

A study on hypnosis also supporters their argument, the researchers claim. Through hypnosis, subjects’ perception of reality and emotions can be influenced by outside suggestions, the scientists said.

Instead of emotions and thoughts making up human consciousness, Oakley and Halligan argue, people’s awareness of those processes and the personal narrative they construct to explain them is true consciousness. 

But while humans may not be able to control thoughts and emotions, this doesn’t mean everyone has free license to do whatever they want, the researchers said.

“Just because consciousness has been placed in the passenger seat, does not mean we need to dispense with important everyday notions such as free will and personal responsibility,” they wrote.

Researchers: Thoughts, emotions may not come from human consciousness

Picnic-lovers take heed: Disease-ridden flies carry a lot more germs than previously suspected. Between them, houseflies and blowflies alone house more than 600 bacteria, many of them linked to human illnesses, according to a new study.

An international team of biologists and entomologists collected sample flies from around the world and analyzed their DNA. 

“We sampled 116 individual houseflies and blowflies from varying habitats on three continents and subjected them to high-coverage, whole-genome shotgun sequencing,” the study said.

They then used the DNA to analyze the flies’ microbiomes – communities of bacteria on their bodies. 

They found that both houseflies and blowflies carry hundreds of bacteria – more than 350 for the housefly, and a little over 300 for blowflies. Many of the bacteria are pathogens like Helicobacter pylori, linked to stomach ulcers in humans. 

The flies often feed on feces and decaying organic matter, the study said – ripe breeding grounds for bacteria. On top of that, their legs and wings showed the greatest diversity of bacteria, and were the most likely parts of the flies to transmit that bacteria to other surfaces. Burger fixings sitting uncovered for hours on a picnic table, for example. 

The disease-ridden flies may transmit more illnesses to humans than epidemiologists and public health officials suspected, the researchers told the <a href="https://www.bbc.co.uk/">BBC</a>. 

“We believe that this may show a mechanism for pathogen transmission that has been overlooked by public health officials, and flies may contribute to the rapid transmission of pathogens in outbreak situations," Dr. Donald Bryant, a study co-author at Pennsylvania State University, told the news agency.

Because flies are so widespread in most ecosystems, they play a large role in how bacteria is spread throughout a community, the researchers said. 

"It will really make you think twice about eating that potato salad that's been sitting out at your next picnic," Bryant told the BBC.

The study has been published in the journal <a href="https://www.nature.com/articles/s41598-017-16353-x">Scientific Reports</a>.

On the unforgiving landscape of North Greenland, temperatures drop and sunlight barely penetrates through the polar winter. It was here, however, that an international team of scientists found <a href="https://www.earth.com/news/predatory-worms-were-terror-beasts-half-a-billion-years-ago/#google_vignette" target="_blank" rel="noreferrer noopener">evidence of sea monsters</a> that would change our understanding of ocean life in the past.



This video captures the discovery of Timorebestia fossils that had been hidden for more than 500 million years in the Sirius Passet formation. The "terror beasts," as they are called, are a hidden chapter in the evolutionary history of <a href="https://www.earth.com" target="_blank" rel="noreferrer noopener">Earth</a>, showing that sophisticated predator-prey interactions occurred much earlier than previously envisioned.



Dr. Jakob Vinther and his research team at the <a href="https://www.bristol.ac.uk/" target="_blank" rel="noreferrer noopener">University of Bristol</a>, in collaboration with researchers at the <a href="https://eng.kopri.re.kr/" target="_blank" rel="noreferrer noopener">Korean Polar Research Institute</a>, braved extreme weather conditions at 82.5 north latitude to locate these giant creatures. Using sophisticated electron microprobe analysis, they revealed the detailed anatomy of the animals, including their muscle and nerve tissues.



The find upsets the traditional timeline of sea predators. Although we've long appreciated that Cambrian oceans were at one time ruled by <a href="https://www.youtube.com/watch?v=jWI3-UgA3_o&amp;list=PL1QLQMW9MWDwpkFOnvgAmu7wT6rZmYqdJ&amp;index=19" target="_blank" rel="noreferrer noopener">arthropods</a>, these discoveries indicate that relatives of arrow worms were first to dominate the seas. These worms were building sophisticated food webs several million years before other predator groups arose.



Each fossil is a story of ancient hunger, with fossil stomach contents revealing these meter-long beasts dined on heavily armored arthropods regularly, cementing their place as the ocean's first apex predators.

<h2 class="wp-block-heading" id="h-385-million-year-old-trees-discovered">385-million-year-old trees discovered</h2>



Scientists have uncovered something extraordinary just two hours north of New York City. The <a href="https://www.earth.com/news/worlds-oldest-forest-discovered-close-to-new-york-city/" target="_blank" rel="noreferrer noopener">world's oldest forest</a>, dating back 385 million years, offers a window into how Earth's first complex forests shaped our planet's atmosphere.



Located near <a href="https://townofcairo.com/" target="_blank" rel="noreferrer noopener">Cairo, New York</a>, in Greene County, these weren't merely primitive plants struggling to survive. These were sophisticated trees with root systems remarkably similar to modern forests. This ancient woodland predates dinosaurs by 140 million years.



<h2 class="wp-block-heading" id="h-the-cairo-forest-discovery">The Cairo forest discovery</h2>



385 million years ago, upstate New York was a tropical paradise near the equator. Thanks to continental drift, this ancient forest has traveled thousands of miles to its current location.



The fossil forest sits in an abandoned quarry, roughly half the size of a football field. This represents just a slice of what was likely a massive forest system stretching from New York into Pennsylvania.



Charles Ver Straeten, curator of sedimentary rocks at the <a href="https://www.nysm.nysed.gov/" target="_blank" rel="noreferrer noopener">New York State Museum</a>, made the discovery in 2009. While scouting the former highway department property, his trained eye spotted wandering patterns in the stone that looked like marine features.



<h2 class="wp-block-heading" id="h-revolutionary-age-and-preservation">Revolutionary age and preservation</h2>



The site contains 385-million-year-old rocks with fossilized woody roots forming horizontal patterns up to 18 feet (5.5 meters) wide. As Christopher Berry, a paleobotanist at Cardiff University, explains: "You are walking through the roots of ancient trees."



This discovery pushes back advanced tree evolution by millions of years. The research, published in <a href="https://www.cell.com/current-biology/home" target="_blank" rel="noreferrer noopener">Current Biology</a> in December 2019, fundamentally changes our understanding of when complex forests first emerged.



Researchers believe a massive flood buried the forest floor, creating perfect fossilization conditions. Over millions of years, sediment hardened into rock, preserving these root patterns like nature's time capsule.



<h2 class="wp-block-heading" id="h-meet-archaeopteris-the-first-modern-tree">Meet Archaeopteris: the first modern tree</h2>



The star of this ancient forest is Archaeopteris – not to be confused with the feathered dinosaur Archaeopteryx. This tree was far older and more revolutionary.



William Stein from <a href="https://www.binghamton.edu/" target="_blank" rel="noreferrer noopener">Binghamton University</a> describes the roots as "strikingly modern, essentially what you'd see outside in my yard right now." These weren't simple root systems you'd expect from ancient plants.



Some fossilized roots are six inches (15 centimeters) in diameter, forming 36-foot-wide (11-meter) patterns. These giants grew up to 65 feet (20 meters) tall with five-foot-diameter (1.5-meter) trunks.



<h2 class="wp-block-heading" id="h-climate-changing-impact">Climate-changing impact</h2>



These trees fundamentally changed Earth's environment. Kevin Boyce, a Stanford University geoscientist, explains how their deep roots triggered "weathering," chemical reactions that pulled carbon dioxide from the atmosphere.



This process dropped atmospheric CO2 levels from 10-15 times higher than today to roughly modern concentrations. These ancient trees helped create atmospheric conditions that made complex life possible.



<h2 class="wp-block-heading" id="h-ancient-forest-ecosystem">Ancient forest ecosystem</h2>



The forest was remarkably diverse. Scientists identified Eospermatopteris, palm tree-like plants with short roots that reached 30 feet (9 meters) tall but lacked woody structure. The forest also housed cladoxylopsids and a mysterious third species still being studied.



All reproduced through spores rather than seeds – millions of years before seeds evolved. This tropical environment had no grass, flowers, or flying insects, just towering trees creating Earth's first complex forest canopy.



<h2 class="wp-block-heading" id="h-scientific-significance">Scientific significance</h2>



Before this finding, the Gilboa forest, located 25 miles (40 kilometers) away, held the "oldest forest" title. Cairo's trees are 2-3 million years older, showing that complex forest ecosystems developed much faster than scientists believed possible.



Patricia Gensel, a <a href="https://www.unc.edu/" target="_blank" rel="noreferrer noopener">University of North Carolina</a> paleobotanist, notes: "The size of those root systems is really changing the picture. Even 20 years ago, researchers assumed trees with such complex root systems didn't evolve so early."



The Cairo site presents three unique root systems, suggesting Devonian period forests were diverse ecosystems with different trees occupying different environmental niches, much like today's forests.



<h2 class="wp-block-heading" id="h-modern-preservation-efforts">Modern preservation efforts</h2>



In 2022, New York State Senator Michelle Hinchey secured a $170,000 grant for the town of Cairo to construct specialized fencing around the fossil forest site. The town plans to conduct a feasibility study exploring the possibility of creating an educational center and working lab on-site.



Joe Hasenkopf, chair of the Cairo Planning Board, hopes to partner with educational institutions to create a research facility serving scientists, students, and the public.



<h2 class="wp-block-heading" id="h-lessons-for-today-s-climate">Lessons for today's climate</h2>



Why does a 385-million-year-old forest matter today? It shows how dramatically forests can change Earth's climate. These ancient woodlands created the atmospheric conditions supporting complex life.



Understanding how prehistoric forests transformed the planet helps us appreciate modern forests' critical role in addressing climate change. Forests remain Earth's most effective carbon capture systems.



These prehistoric trees changed Earth's atmosphere by pulling massive amounts of carbon dioxide from the air. As we face modern climate challenges, this ancient forest reminds us of trees' incredible power to transform our planet's environment.



The next time you walk through a forest, remember you're experiencing an ecosystem whose blueprint was established 385 million years ago in upstate New York. These ancient pioneers didn't just survive – they thrived and changed the world forever.



The full study was published in the journal Current Biology.

</div><figcaption class="wp-element-caption">Acid rain and a crisis solved.</figcaption></figure>



<h2 class="wp-block-heading" id="h-why-don-t-we-ever-hear-about-acid-rain-anymore-the-environmental-crisis-that-was-solved">Why don't we ever hear about "acid rain" anymore? The environmental crisis that was solved</h2>



Remember the 1980s when acid rain dominated headlines? Dire warnings about rain eating buildings, killing fish, and destroying forests filled every news cycle. Then, almost like magic, acid rain vanished from public discourse. What happened? Did we actually solve one of the late 20th century's most pressing environmental challenges?



The answer might surprise you. Unlike many environmental issues that drag on indefinitely, acid rain represents one of modern history's most successful ecological recovery stories. It's a tale of science, politics, and technology working together to tackle what seemed impossible.



<h2 class="wp-block-heading">What was acid rain?</h2>



Acid rain isn't regular rain having a bad day – it's precipitation that became significantly more acidic due to air pollution. When power plants, factories, and vehicles burn fossil fuels, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.



<h2 class="wp-block-heading">The science behind it</h2>



Think of acid rain as nature's chemistry experiment gone wrong. These compounds react with water, oxygen, and other chemicals to form sulfuric and nitric acids. When mixed with water vapor in clouds, they create precipitation with dangerously low pH levels.



While clean rain has a pH of about 5.6, acid rain could drop as low as 4.2 to 4.4 – roughly as acidic as tomato juice or coffee. According to US Geological Survey documentation, Scottish chemist Angus Smith first coined "acid rain" in 1872, but it didn't become a household phrase until the 1960s and 1970s when Swedish scientist Svante Odén documented its devastating effects on Scandinavian lakes and European forests.



<h2 class="wp-block-heading">The crisis at its peak</h2>



During the height of public concern, environmental damage was both widespread and visible. This wasn't some abstract future threat – people could see destruction happening in real-time.



<h2 class="wp-block-heading">Environmental devastation</h2>



The most dramatic impacts were impossible to ignore. Research documented by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation shows that in the Adirondack Mountains, more than 200 lakes became so acidic they couldn't support fish life. The Adirondack Council reports that 409 lakes once supported brook trout, but many lost their fish populations due to acid rain.



By 1976, when scientists cataloged all acidified lakes in the Adirondack Park, researchers found that half of the lakes over 2,000 feet above sea level had no fish, according to studies published in environmental journals. The acidification process worked like a slow-motion disaster. As acid rain fell into watersheds, it gradually lowered pH levels. Fish couldn't survive in acidic water, and their food sources died off too.



Trees at high elevations showed stress directly linked to acid rain. It weakened them by leaching nutrients and making them susceptible to disease. Historical records show Germany's Black Forest saw nearly half its trees damaged by the mid-1980s.



<h2 class="wp-block-heading">Economic impact</h2>



Acid rain wasn't just environmental – it was expensive. Acidic precipitation corroded infrastructure, buildings, and monuments. Historic stone structures deteriorated at accelerated rates. Tourism suffered as lakes became fishless and forests declined. EPA economic analyses from the period documented repair costs mounting into billions annually.



<h2 class="wp-block-heading">The solution: government action and technology</h2>



Transformation from crisis to success required unprecedented cooperation between governments, industries, and environmental groups.



<h2 class="wp-block-heading">The Clean Air Act of 1990</h2>



The turning point came with the Clean Air Act Amendments of 1990, signed by President George H.W. Bush. This represented a fundamentally new approach to environmental regulation, as documented in EPA historical records.



<h2 class="wp-block-heading">Cap-and-trade success</h2>



Instead of mandating specific technologies, the 1990 amendments introduced something revolutionary: a cap-and-trade system for sulfur dioxide emissions. EPA program documentation shows this market-based approach set overall limits but allowed companies to trade emission allowances.



The genius was harnessing market forces to find cost-effective pollution reduction. Companies reducing emissions cheaply could sell excess allowances to those facing higher costs. Research published in environmental economics journals and EPA progress reports shows this resulted in dramatic SO2 reduction at a fraction of projected costs.



<h2 class="wp-block-heading">Technology advances</h2>



Policy provided the framework, but technology made reductions possible. Studies in atmospheric science journals document the widespread adoption of flue gas desulfurization systems ("scrubbers") that removed sulfur dioxide before it reached the atmosphere. By the 2000s, new installations could remove over 95% of SO2 emissions, according to EPA technical reports.



The push coincided with cleaner energy development. Natural gas produces fewer sulfur compounds than coal. Wind and solar, emerging in the 1990s, captured growing market share, reducing reliance on high-sulfur coal.



<h2 class="wp-block-heading" id="h-why-we-don-t-hear-about-it-today">Why we don't hear about it today</h2>



Why did acid rain disappear from headlines? Simple: the problem was largely solved.



<h2 class="wp-block-heading">Success doesn't make news</h2>



There's an old journalism saying: "If it bleeds, it leads." Environmental success stories don't generate urgency like crisis reporting. Media attention shifted to other challenges: climate change, plastic pollution, and biodiversity loss. There's only so much environmental anxiety the public can absorb, and newer concerns replaced acid rain.



<h2 class="wp-block-heading">Mission accomplished</h2>



The primary reason is beautifully simple: interventions worked. EPA monitoring data shows sulfur dioxide emissions dropped over 90% since 1990. Academic research published in environmental science journals confirms pH levels in formerly affected areas returned closer to normal. This represents one of history's most dramatic environmental recoveries. Studies by the Adirondack Lakes Survey Corporation show fishless lakes now support healthy populations. Forests recovered, and building damage slowed dramatically.



<h2 class="wp-block-heading" id="h-is-it-really-gone">Is it really gone?</h2>



The crisis is largely resolved, but monitoring data shows the problem isn't completely eliminated – it's managed to acceptable levels. Some areas still experience occasional events during high pollution periods. International environmental research indicates that rapidly industrializing Asian countries face similar problems to what we experienced decades ago, though they're implementing successful strategies.



EPA research shows nitrogen oxide emissions proved more challenging than sulfur dioxide, coming from vehicles and mobile sources. Climate science studies suggest changing weather patterns add complexity to how acid rain forms and falls.



<h2 class="wp-block-heading">What this teaches us</h2>



The acid rain experience proves that seemingly intractable environmental problems can be solved with scientific understanding, political will, and technological innovation. Environmental monitoring data shows recovery speed was remarkable – within a decade, measurable improvements appeared in air quality and ecosystem health.



Success came from bipartisan support across party lines. Policy analysis studies show the market-based approach appealed to those preferring economic incentives while achieving environmental goals. This support created lasting policy surviving political changes.



<h2 class="wp-block-heading">Conclusion</h2>



Acid rain's disappearance from public consciousness represents environmental science's greatest success stories. Through effective regulation, technological innovation, and international cooperation, we transformed an overwhelming crisis into a manageable challenge.



Today's silence isn't because we forgot – it's because we solved it. The 1990 Clean Air Act, combined with technology and energy market changes, reduced acid rain emissions over 90%, according to comprehensive EPA data analysis.



This success offers hope for current challenges. It proves complex problems can be solved when science, policy, and technology work together. As we face climate change and plastic pollution, acid rain reminds us that dramatic positive change is possible.



Next time someone asks whether environmental regulations work, remember acid rain. It's proof that sometimes, we get it right.

<h2 class="wp-block-heading">Frequently Asked Questions</h2>



1. Is acid rain completely gone? No, but EPA monitoring shows it's reduced to manageable levels. US sulfur dioxide emissions dropped over 90% since 1990, making acid rain much less severe than the 1980s crisis.



2. How long did solving take? Environmental monitoring data shows significant improvements began within 5-10 years of 1990s emission controls. Full ecosystem recovery took longer – some areas need 20-30 years for complete recovery.



3. What made the solution successful? Clear scientific understanding, visible damage motivating action, bipartisan support, available technology, and innovative market-based policies like cap-and-trade.



4. Do other countries have acid rain problems? Yes, particularly rapidly industrializing Asian countries. However, international environmental research shows many implement similar successful control strategies.



5. Could acid rain return? Potentially, if regulations weaken or we return to high-sulfur coal without controls, though effects would take years to become severe according to environmental projections.



6. Can you recommend any teaching tools on the subject of "acid rain"? The United States Environmental Protection Agency produced a wonderful teacher's guide for ages 14 and under that you can find on the EPA website here: <a href="https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf" target="_blank" rel="noreferrer noopener">https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf</a>

Mid-July is an opportune time to kick-start a thriving fall garden, and this guide lays out the best vegetables and herbs to plant now for a fruitful autumn harvest. 



Fast-growing leafy greens such as spinach, lettuce, kale, and arugula perform especially well in the waning summer heat, with harvests beginning as soon as 30 days. 



These cool-season crops relish the transition into fall, offering repeated yields with cut-and-come-again methods.



Root vegetables like radishes, carrots, and beets also excel during this period. Radishes deliver satisfaction in under a month, while carrots and beets mature in about two months. Employing succession planting ensures a continuous stream of produce deep into the cooler months. 



For a boost of fresh flavor, herbs like cilantro, basil, dill, and chervil are excellent picks. These heat-loving varieties flourish in July’s warmth and are harvest-ready in about 30 days, especially when sown continuously.



Gardeners in zones 6 through 9 can benefit from planting bush beans and snap peas, which don’t require trellising and are ideal for compact plots. 



Maturing in 50–60 days, they’re a smart choice for quick, protein-rich harvests. For those in hotter regions, heat-tolerant crops such as okra and southern peas provide reliable yields and thrive in scorching conditions.



This guide emphasizes more than crop selection—it highlights the importance of timing, soil preparation, and ongoing sowing techniques. 



With thoughtful planning and attention to regional climate needs, even late-summer gardeners can enjoy fresh salads, hearty stews, and the satisfaction of a robust, homegrown harvest well into fall.

A new long-term study in Monkton, Vermont, reveals that wildlife tunnels significantly reduce amphibian road mortality during seasonal migrations. 



Frogs and salamanders often cross roads to reach breeding ponds each spring, but many are killed by vehicles. 



Researchers from the <a href="https://www.uvm.edu/" target="_blank" rel="noreferrer noopener">University of Vermont</a>, in collaboration with local citizens and the Vermont Agency of Natural Resources, installed two underpass tunnels in 2015. 



Over a 12-year monitoring period, they observed an 80.2% reduction in amphibian deaths, and up to 94% for non-climbing species like salamanders. 



The study used a before-after-control-impact design and documented more than 5,200 amphibians, highlighting the tunnels’ effectiveness even in nearby buffer zones.



Funded at $342,397 - far cheaper than wildlife crossings for large mammals - the project showcased the power of community-led conservation.



Local groups initiated the effort after observing mass amphibian deaths. Wildlife cameras later captured over 2,200 amphibians using a tunnel in just one spring, along with other species like raccoons and bobcats, indicating wider ecosystem benefits.



This marks the first peer-reviewed, long-term data set in the northeastern U.S. confirming amphibian-specific underpasses work. 



The study urges transportation departments to incorporate these designs into road planning and highlights how community action, thoughtful infrastructure, and persistence can make a real difference for biodiversity.



The full study was published in the <a href="https://linkinghub.elsevier.com/retrieve/pii/S1617138125000780" target="_blank" rel="noreferrer noopener">Journal for Nature Conservation</a>.

Wildlife tunnels save millions of amphibians

https://youtu.be/XYgiPzmNBTU?si=eFYY7gPHU1JznLvU A new long-term study in Monkton, Vermont, reveals that...

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.

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;

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



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

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



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



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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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

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



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



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



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