Egyptian rituals have long captivated the imaginations of scholars and enthusiasts alike, and a recent breakthrough has demystified some of their most mysterious aspects.



In an incredible leap forward for archaeology and anthropology, a new study has provided tangible proof that the use of hallucinogenic mixtures was an integral part of this ancient civilization's sacred practices.



The physical evidence of hallucinogens was found in an Egyptian Bes mug, a rare relic stored in a collection at the Tampa Museum of Art.



These curious objects are distinctively adorned with the ferocious face of Bes, a protective deity linked to everything from fertility to magical healing.

This research didn't materialized overnight. The role of the Bes mugs in ancient Egyptian society has been a topic of debate for a long stretch of time.



“For a very long time now, Egyptologists have been speculating what mugs with the head of Bes could have been used for, and for what kind of beverage, like sacred water, milk, wine or beer,” noted Branko van Oppen, a museum curator at the Tampa Museum of Art.



The ubiquity of the mugs throughout different epochs made it tough to pinpoint their exact use and significance.



The cryptic puzzle finally began to fall into place when researchers from the <a href="https://www.usf.edu/" target="_blank" rel="noreferrer noopener">University of South Florida</a> embarked on an ambitious project to explore the unknown.



“There’s no research out there that has ever found what we found in this study,” said Davide Tanasi, lead author of the research paper that presents the findings.



The team managed to dissect the chemical signatures of a long-dried liquid inside one of the Tampa Museum's Bes mugs, providing a concrete clue to its past use.



<h2 class="wp-block-heading" id="h-the-secret-concoction-used-in-egyptian-rituals">The secret concoction used in Egyptian rituals</h2>



The result was nothing short of astounding. The researchers discovered a blend of <a href="https://www.earth.com/news/psychedelic-drugs-secreted-from-toad-skin-greatly-improve-cognitive-functioning/" target="_blank" rel="noreferrer noopener">psychedelic drugs</a>, bodily fluids, and alcohol inside the mug - a 'cocktail' likely used in a ritual re-enacting an Egyptian myth.



The mysterious brew was sweetened with popular ingredients of the time like honey, sesame seeds, pine nuts, licorice, and grapes, quite possibly to mimic the appearance of blood.



<h2 class="wp-block-heading" id="h-a-glimpse-into-ancient-life">A glimpse into ancient life</h2>



This astounding find has brought to life vivid images of the Greco-Roman period in <a href="https://www.earth.com/news/egypts-pyramids-were-built-along-a-buried-branch-of-the-nile-river/" target="_blank" rel="noreferrer noopener">Egypt</a>. 



The historical significance of the discovery underlines the importance of the Bes Chambers at Saqqara, a site apparently frequented by individuals hoping to confirm a successful pregnancy - a perilous phase in the ancient world.



“Egyptologists believe that people visited the so-called Bes Chambers at Saqqara when they wished to confirm a successful pregnancy because pregnancies in the ancient world were fraught with dangers," explained Van Oppen. 



He believes the special brew was likely used in a dream-vision inducing ritual during this fraught period.



This unusual study has helped us connect the dots between myths and reality.



“With this study, we’ve found scientific proof that the Egyptian myths have some kind of truth and it helps us shed light on the poorly understood rituals that were likely carried out in the Bes Chambers in Saqqara, near the Great Pyramids at Giza,” explained Tanasi.



Thus, the shroud of mystery surrounding ancient Egyptian rituals is gradually lifting, one artifact at a time.



<h2 class="wp-block-heading" id="h-symbolism-of-bes-in-egyptian-rituals">Symbolism of Bes in Egyptian rituals</h2>



The discovery of <a href="https://www.earth.com/news/peruvian-empire-kept-control-with-beer-and-hallucinogens/" target="_blank" rel="noreferrer noopener">hallucinogenic substances</a> within the Bes mug not only sheds light on the practices of ancient Egyptian rituals but also emphasizes the cultural weight carried by Bes, the deity represented on the artifact. 



Known for his lion-like visage and protective nature, Bes held an essential place in daily life and spiritual practices. He was not just a guardian deity; he was seen as a figure that could ward off evil spirits, promote <a href="https://www.earth.com/news/mediterranean-diet-improves-sperm-quality-and-fertility/" target="_blank" rel="noreferrer noopener">fertility</a>, and bring joy through music and dance.



In ancient Egypt, rituals involving Bes were believed to harness his powerful essence, particularly in times of vulnerability, such as childbirth and healing. 



The presence of hallucinogenic elements in the brew suggests that these ceremonies aimed to elevate participants' consciousness and induce a trance-like state for divine communication or visionary experiences.



Such practices aligned with the belief that connecting with deities like Bes could provide spiritual protection and guidance.



This new understanding of Bes' involvement in these rituals deepens our appreciation for how ancient <a href="https://www.earth.com/news/mystery-how-ancient-egyptians-built-pyramids-djoser-may-be-solved/" target="_blank" rel="noreferrer noopener">Egyptians</a> intertwined the mystical with the tangible, creating sacred ceremonies that reflected their belief in the interconnectedness of the human and divine realms.

Hallucinogens were used in ancient Egyptian rituals

Egyptian rituals have long captivated the imaginations of scholars and enthusiasts alike, and a recent breakthrough has demystified some of their most mysterious aspects. In an incredible leap forward for archaeology and anthropology, a new study has provided tangible proof that the use of hallucinogenic mixtures was an integral part of this ancient civilization's sacred practices. The physical evidence of hallucinogens was found in an Egyptian Bes mug, a rare relic stored in a collection at the Tampa Museum of Art. These curious objects are distinctively adorned...

Heart attacks have gotten less deadly and less common since the 90s. The saying “as serious as a heart attack” may have to take on a less-dramatic meaning due to the recent findings of a <a href="https://www.yale.edu/">Yale University</a> study published in <a href="https://jamanetwork.com/journals/jamanetworkopen">JAMA Network Open</a>. The study found that – compared to the mid 1990s – Americans today are less likely to have heart attacks and also less likely to die from them.

Researchers tracked over four million Medicare patients between 1995 and 2014 as part of the largest and most comprehensive study of <a href="http://www.earth.com/news/heart-attack-stroke-unemployment/">heart attacks</a> ever in the United States. In this effort, they found that hospitalizations for heart attacks have declined by almost 40%, and the 30-day mortality rate for heart attacks is at an all-time low of 12%. 

Yale cardiologist Harlan Krumholz believes that these trends are a result of the last two decades of national efforts to prevent heart attacks and improve care for those who suffer them. These efforts have included the promotion of healthy lifestyles, focus on risk factors, and improvement in quality of care spearheaded by the Centers for Medicare and Medicaid Services, the American College of Cardiology, and the American Heart Association.

Although this is good news for the nation as a whole, the study does shed light on health outcome disparities in America. 

“Priority health areas,” which had been previously identified as lagging areas, saw little to no change in 30-day mortality rates in the past two decades. The researchers state that these areas should be receiving more focused attention in future healthcare improvement activities.

“We are now at historic lows in the rates of heart attacks and deaths associated with heart attacks,” says Krumholz. “However, this is no time to be complacent. We document extraordinary gains – but the effort is far from finished. The goal is to one day relegate heart attacks to the history of medicine.”

A team of researchers has found that the benefits of living in a walkable neighborhood could be outweighed by exposure to traffic-related <a href="http://www.earth.com/news/visiting-city-air-pollution-breathing-issues/">air pollution</a>. The study was led by <a href="http://www.stmichaelshospital.com/">St. Michael's Hospital</a> and ICES, a non-profit research institute which addresses a broad range of health care issues.

The investigation was focused on nearly 2.5 million adults in 15 districts of Ontario. The study findings contradict the idea that all walkable neighborhoods provide Canadian residents with an opportunity for improved overall health and well-being.

Study co-lead author Dr. Gillian Booth is a scientist at St. Michael's Hospital's MAP Centre for Urban Health Solutions and at ICES.

"Previous research has shown that individuals living in more walkable neighborhoods are more physically active, with downstream health benefits like lower rates of overweight and obesity, hypertension and diabetes," said Dr. Booth. "But our findings confirm that walkability and air pollution are highly intertwined, potentially diminishing any health benefits derived from living in walkable, urban communities."

According to the researchers, individuals in unwalkable neighborhoods have a higher risk of diabetes or hypertension compared to those living in most walkable communities. However, the health benefits of walkable areas were found to decrease, or even disappear, as concentrations of air pollution increased.

"Individuals living in highly walkable neighborhoods tend to be more likely to choose active forms of transportation, like walking or bicycling, as an alternative to driving," explained study co-lead author Dr. Nicholas Howell. "So they may be more exposed to air pollution based simply on the amount of time they spend outside."

The research suggests that the development of walkable neighborhoods should coincide with strategies to mitigate residents' exposure to air pollution.

"Initiatives to create walkable communities while decreasing sources of car pollution may have promise to reap even greater health benefits and have a stronger impact on the health of Canadians," said Dr. Howell.

The study is published in the journal <a href="https://www.journals.elsevier.com/environment-international">Environment International</a>.

Heart disease is a leading cause of death in the United States, responsible for 1 out of every 4 deaths each year, according to the <a href="https://www.cdc.gov/heartdisease/facts.htm">Centers for Disease Control</a> (CDC).

Now, a new study conducted by researchers from the <a href="https://www.cnic.es/en">Spanish National Center for Cardiovascular Research (CNIC)</a> shows that sleep has a significant impact on heart health and too little sleep can increase the risk of cardiovascular disease by up to 35 percent.

“Cardiovascular disease is a major global problem, and we are preventing and treating it using several approaches, including pharmaceuticals, physical activity and diet,” said José M. Ordovás, the senior author of the study. “But this study emphasizes we have to include sleep as one of the weapons we use to fight heart disease--a factor we are compromising every day.”  

Previous studies have shown that too little or too much sleep can increase the risk of <a href="https://www.earth.com/news/sleep-heart-disease/">heart disease</a> and can cause problems with memory, focus, and mood.

For this study, the researchers found similar results and both sleeping too little (less than six hours a night) or too much (over eight hours a night) increased the risk of heart disease, specifically, atherosclerosis which is when plaque builds up in the arteries.

“This is the first study to show that objectively measured sleep is independently associated with atherosclerosis throughout the body, not just in the heart,” said Ordovás.

The researchers also found that quality of sleep, as well as length, influence cardiovascular disease risk.

The study was published in the <a href="http://www.onlinejacc.org/content/73/2/134">Journal of the American College of Cardiology</a>.

Ordovás and colleagues asked members of the<a href="https://www.cnic.es/en/investigacion/proyectos-clinicos/pesa-cnic-santander"> PESA CNIC- Santander Study</a> to take part in the in the new study where overall 3,974 bank employees from Spain were included in the research. 

The participants didn’t have a history of heart disease, and the researchers asked the participants to wear an actigraph for seven days to record sleep quality and length. Actigraphs measure activity and movement throughout the wearer’s day.

After the week was up, the researchers split the participants into groups depending on how much sleep they got each night. The researchers also took 3D heart ultrasounds and CT scans of the participants to find any signs of heart disease.

Participants that slept less than six hours were 27 percent more likely to have plaque built up in their arteries. Participants who had poor sleep including trouble staying asleep or waking up in the middle of the night had a 34 percent higher likelihood of atherosclerosis.

Sleeping over eight hours was also linked to an increased risk of heart disease and both caffeine and alcohol disrupted normal sleeping patterns.

The research suggests that sleeping patterns need to be considered as a preventive measure to help guard against heart disease, but more work is needed to see if changing sleep patterns will help reduce the risk of heart disease.

American adults spend close to half of their waking hours looking at screens, according to a new survey from contact lens manufacturer <a href="https://coopervision.com/">CooperVision</a>. The study revealed that our eyes are generally looking at a television, computer, <a href="http://www.earth.com/news/smartphones-sleep-deprivation-kids/">smartphone</a>, or another device around 42 percent of the time we are awake. 

Based on eight hours of sleep per night, the researchers estimated that the average American is in front of a screen for six hours and 43 minutes every day. This means that we have more than 47 hours of screen time in a typical week. 

According to the survey, the amount of time we spend looking at screens is rapidly rising. Around 80 percent of survey respondents said that their screen time has increased over the last five years, while 75 percent admitted they spend too much of their time fixated on their computer, smartphone, or television. 

More than half of the individuals surveyed said that they take breaks from their computer to check their phone, and more than a quarter of participants reported looking at the phone and watching TV at the same time. 


“We live in a digitally-connected world and these survey results show how digital devices have completely transformed our lives, no matter our age,” said Dr. Michele Andrews, who is an optometrist with CooperVision. ‘Digital eye fatigue is faced by millions of Americans every day because of this non-stop screen time.”


The researchers determined that we can stare at a screen for around four hours before experiencing eye discomfort. The study also revealed that the amount of screen time varies significantly with age, with millennials feeling the most attached to their devices. 

Overall, only half of the survey respondents agreed that society as a whole has become more screen-focused over the past five years. In addition, 73 percent of the individuals said too much screen time makes them feel lethargic, and 64 percent feel happier when they step away from the screen.

As <a href="https://www.earth.com/news/rates-loneliness-doubled/">we reported</a> last year, rates of loneliness have doubled over the past 50 years, despite the ability to connect online at almost any time. Since pharmaceutical solutions seem to be available for most other ailments, many have questioned if a pill could cure one of humanity’s greatest epidemics and hardest to treat afflictions.

This is the current goal of Dr. Stephanie Cacioppo, a neuroscientist who has studied loneliness for most of her career, and recently spoke to the <a href="https://www.dailymail.co.uk/health/article-6598703/A-pill-loneliness-Scientists-race-treat-condition-raise-premature-death-risks.html">Daily Mail</a> on her efforts to develop a loneliness cure.

With social media platforms and the internet connecting people all over the world in the blink of an eye, you would think loneliness would be a thing of the past. 

However, research has shown that people today feel more<a href="https://www.earth.com/news/loneliness-rise-united-states/"> isolated despite social media’s connectivity</a> and that pervasive loneliness impacts health and wellbeing, especially among younger generations. 

One 2018 nationwide survey of 20,000 US adults found that around <a href="https://www.npr.org/sections/health-shots/2018/05/01/606588504/americans-are-a-lonely-lot-and-young-people-bear-the-heaviest-burden">50 percent of the survey respondents felt lonely some or all of the time</a>. Studies have found links between loneliness and an increased risk of <a href="https://www.nytimes.com/2017/12/11/well/mind/how-loneliness-affects-our-health.html">diabetes, dementia, and cardiovascular disease</a>. 

Cacioppo recently had to deal with loneliness head-on after the sudden death of her husband, an event that motivated her to continue on with her research into what loneliness does to the brain and how to potentially treat it. 

A cure for loneliness may be closer than you think as Cacioppo found that pregnenolone (a steroid naturally made in the body) can help combat the anxiety that comes with feelings of loneliness. 

Several test studies and trials have shown that participants given pregnenolone have less activity in the amygdala and insula parts of the brain compared to control groups. These regions in the brain are linked to the flight or fight response and help people process and perceive threats around them. 

Cacioppo is in the process of analyzing data from a clinical trial in which 96 participants who reported feeling lonely were given different amounts of the steroid or a placebo. If the results are successful, Cacioppo and her team could soon develop a pill form of the steroid which could help ease the anxiety and negative symptoms of loneliness.

How thinking globally, but acting locally can make a difference. The idea that having narrow local focus leaves little room for anything but a selfish mindset is a misconception, according to a new study that found that concern for local issues could help with <a href="https://www.earth.com/news/global-warming-industrial-revolution/">global environmental conservation</a>. 

You might have heard of the acronym <a href="https://www.britannica.com/topic/Not-in-My-Backyard-Phenomenon">NIMBY</a> which means “not in my backyard” and describes an individual or group opposed to a new addition to the neighborhood, typically a factory, roadway or power station. Nimbyism and parochialism, which is a focus on a local area, can go hand in hand, and there are concerns that parochialism paves the way for bigotry, prejudice, narrow-mindedness, and selfishness. 

But researchers from the <a href="https://www.exeter.ac.uk/">University of Exeter</a> found the exact opposite to be true in a new study published in the journal Transactions of the Institute of British Geographers. 

The researchers argue that positive parochialism can inspire a larger awareness of global environmental issues and spur people to action. 

“We did not find evidence that parochialism was inevitably negative and inward-looking,” said Patrick Devine-Wright, a researcher for the study. “It can be those things, but there's no necessary conflict between feeling connected to your local area and feeling connected to the wider world.” 

For the study, the researchers reviewed archival material from the <a href="https://www.commonground.org.uk/parish-maps/">1987 Parish Maps project </a>which was started by the UK charity <a href="https://www.commonground.org.uk/">Common Ground</a>. The researchers also conducted interviews with people who had been involved in the project. The Parish Maps project asked communities to create maps of local areas, highlighting important community buildings, parks, and features. 

The maps were not necessarily accurate cartographically speaking but instead emphasized the most important features to a local community. 

For this study, the researchers show how the Parish Maps project also showcased a passion for the environment and conservation. 

“The Parish Maps project was hugely popular at the time, but has been somewhat overlooked since it ended,” said Devine-Wright. “It led to a huge upswell in local environmentalism and the creation of thousands of maps across the UK and beyond. We argue that it represents parochialism without the negative connotations many people associate with that word.”


The researchers say that the Parish Maps project is a strong example of “positive parochialism,” and shows that thinking locally can influence a global mindset. 

“For a long time, the consensus has been that if we want people to think about global issues they need a cosmopolitan worldview - but this may not be the case,” said Devine-Wright. “Given where we are now in terms of trying to encourage people to make changes to help the environment, ‘positive parochialism’ offers something that has been overlooked.”

A new study from the <a href="https://www.ku.dk/english/">University of Copenhagen</a> shows that, in the region that is now northeast Jordan, people began to live alongside <a href="http://www.earth.com/news/dogs-diagnose-malaria/">dogs</a> as far back as 11,500 years ago. The evidence also suggests that dogs were used for hunting, which would explain the drastic increase of hares and other small prey found at the archaeological dig site at this time.

Although dogs were domesticated by humans as early as 14,000 years ago in the Near East, it has remained unclear whether this happened intentionally. The research indicates that humans valued the tracking and hunting abilities of dogs much earlier than previously realized.

“The study of the large assemblage of animal bones from Shubayqa 6 revealed a large proportion of bones with unmistakable signs of having passed through the digestive tract of another animal; these bones are so large that they cannot have been swallowed by humans, but must have been digested by dogs,” explained study lead author and zooarchaeologist Lisa Yeomans.

The year-round accumulation of bones at the site showed that the dogs were living together with the humans rather than simply visiting the area when it was uninhabited.

“The dogs were not kept at the fringes of the settlement, but must have been closely integrated into all aspects of day-to-day life and allowed to freely roam around the settlement, feeding on discarded bones and defecating in and around the site,” explained Yeomans.

The team noticed a major increase in the number of hares at the same time that dogs appeared at Shubayqa 6.

“The use of dogs for hunting smaller, fast prey such as hares and foxes, perhaps driving them into enclosures, could provide an explanation that is in line with the evidence we have gathered,” said Yeomans. “The long history of dog use, to hunt both small as well as larger prey, in the region is well known, and it would be strange not to consider hunting aided by dogs as a likely explanation for the sudden abundance of smaller prey in the archaeological record."

“The shift may also be associated with a change in hunting technique from a method, such as netting, that saw an unselective portion of the hare population captured, to a selective method of hunting in which individual animals were targeted. This could have been achieved by dogs.”

The study is published in the <a href="https://www.journals.elsevier.com/journal-of-anthropological-archaeology">Journal of Anthropological Archaeology</a>.

According to a new study, the romantic relationships we have in our teens have little impact on our ability to communicate and successfully build <a href="https://www.earth.com/news/relationship-decide-stay-breakup/">romantic relationships</a> as adults. Instead, the friendships we form as teens have a much greater impact on romantic success and satisfaction later on.

Researchers from the <a href="http://www.virginia.edu/">University of Virginia</a> and <a href="https://www.jmu.edu/">James Madison University</a> conducted a long-term study to better understand what factors best predict romantic success as adults.

It’s been previously established that someone’s physical and mental health as a teen has a strong influence on romantic partnerships later on. However, for this study the researchers wondered whether romantic relationships or friendships had a greater impact on future romantic success.

The research was published in the journal Child Development.

“In spite of the emphasis teens put on adolescent romantic relationships, they turn out not to be the most important predictor of future romantic success,” said Joseph P. Allen, the leader of the study. “Instead, it's the skills learned in friendships with peers of the same gender--skills such as stability, assertiveness, intimacy, and social competence--that correspond most closely to the skills needed for success in adult romantic relationships.”

For the study, 165 adolescents ages 13 to 30 participated in the research and the participants were racially, ethnically, and socioeconomically diverse.

The researchers interviewed each participant and conducted interviews each year over the course of three years as participants who were in their teens at the start of the study reached their late 20s.

Participants discussed their social lives, friendship, and romantic partners as well as dating history. When the participants were in their late 20s, the researchers also asked about satisfaction with their current romantic life.

The team identified several key trends and found that friendships were a much stronger predictor of romantic success at ages 27 to 30.

Teens at 13 who were able to openly establish relationship expectations with their friends had greater romantic success later on.

At 15 and 16, the researchers found that the ability to form close friendships and maintain a diverse social circle was another strong predictor.

As the participants progressed into adulthood, the ability to maintain close and stable friendships was a key indicator of romantic success later on. Friendships had the biggest influence on romantic success later on compared to any other factors including adolescent romantic relationships.

“Romantic relationships in adolescence are much more likely to be fleeting, and as such, they don't appear to be the main way teens learn skills needed for the future,” said Rachel K. Narr,  a co-author of the study.

Natural disasters can have a long term impact on student performance. When a <a href="https://www.earth.com/news/global-risk-natural-disasters-doubled/">natural disaster</a> strikes a community, it can be difficult to pick up the pieces, rebuild, and try to fall back into normal patterns of work, school, and home life.

For children, natural disasters can disrupt schooling and classes may even be put on hold temporarily. Researchers from several universities in Australia set out to investigate the long-term effects that a natural disaster can have on academic performance. 

The study, published in the journal Child Development, reviewed several years’ worth of school records from children in Australia that had been impacted by bushfires. 

“Our study is the first in Australia to track the academic performance of elementary-school children affected by a natural disaster over a four-year period,” said Lisa Gibbs, the leader of the study. “The findings highlight the extended nature of academic impact and identify important opportunities for intervention in the education system so children can achieve their full potential.”

24,642 students who had attended primary school in Australia and who had been affected by a severe series of bushfires that spread across Victoria on February 7th, 2009 were included in the study. 

The date is known as Back Saturday because the fires were some of the worst fires in Australia’s history. 

The researchers reviewed each student’s standardized test scores on reading, writing, numeracy, and grammar two and four years after the fires. 

Some of the students had been more impacted by the fires than others, and the researchers took into account property lost, family members affected, lives lost, as well as other demographic and external factors such as home environment and parent’s education. 

Of all the subjects, reading and numeracy had the lowest scores for the children who had been affected by the fires. 

The team also found that schools impacted by the fires saw fewer expected gains in these subjects but subjects like writing and grammar were not affected. 

“Given the apparent delayed impact of the fires, it will be important for future studies on the impacts of disasters on children to extend beyond three years, and to consider academic and cognitive impacts alongside factors related to health and social and emotional well-being,” said Jane Nursey, a co-author of the study. 

The study shows a strong link between poor academic performance and natural disasters. The researchers say the results call for interventions to ensure that students impacted by a natural disaster receive as much emotional and academic support as possible.

Scientists at the <a href="https://en.wikipedia.org/wiki/European_Chemical_Society_(EuChemS)">European Chemical Society</a> (EuChemS) have created a new periodic table that highlights which elements are now considered endangered. Elements such as allium, arsenic, yttrium, and silver have become shockingly scarce and could vanish in less than 100 years at the current rate. 

The experts added a mobile phone symbol to the 31 elements that are used to make phones, hoping to send a powerful message about how much we depend upon these elements in our daily lives. The modified periodic table also distinguishes conflict minerals, which fuel violence and wars in the regions where they are extracted.

David Cole-Hamilton, a professor of Chemistry at the <a href="https://www.st-andrews.ac.uk/">University of St. Andrews</a>, pointed out that all of the conflict minerals are used in <a href="http://www.earth.com/news/smartphones-sleep-deprivation-kids/">cell phones</a>. 

“We have to question whether it’s really necessary to change over mobile phones every year or so. 10 million phones a month are changed in Europe alone. Most of them are sent to the developing world - either for reuse or for recycling - but the recycling is not efficient.”

Professor Cole-Hamilton also explained why we should be far more conservative with helium. He said that while it is widely used for magnetic resonance imaging and deep sea diving, the helium for both of these applications is recycled. 

“But if you have a helium balloon at a birthday party, it will either deflate or burst, and either way the helium is released into the atmosphere,” said Professor Cole-Hamilton. “Helium is so light that once it’s in the atmosphere it can actually escape from the Earth completely and go into outer space where it’s lost to us forever.”

The team hopes to make their periodic table accessible to everyone, and has already made “great progress in getting it into schools across Europe.” The Royal Society of Chemistry will be sending a copy to every one of its 50,000 members.

“It’s amazing to think that everything that we see around us in the natural world is made up from just 90 building blocks - the 90 naturally occurring elements,” said Professor Cole-Hamilton. “Furthermore, these 90 elements, in different combinations, make up all of the wonders of nature, and all the technology and gadgets we use every day. We need to have a better way of dealing with these resources, or we won’t have them anymore.”

The EuChemS version of the periodic table was launched this week at the European Parliament.

Researchers at <a href="https://international.au.dk/">Aarhus University</a> in Denmark have found that, even under the worst global warming conditions, power generated by wind farms and solar panels will still be functioning in Europe by the end of the century. For their investigation, the experts developed a simplified model of Europe’s electricity system and combined it with existing climate models.

“Most other energy system studies assume a number of technologies and seek to combine them in a cost-optimal way to cover the demand,” said first author Smail Kozarcanin. 

“In this study, we seek to understand, for example, how climate change affects the system independent of which technologies are used to cover the demand that remains unmet by wind and solar. To the best of our knowledge, this technology-independent focus in combination with high-resolution data on climate change projections is unique to our study.”

Even under the worst case scenario projected by the Intergovernmental Panel on Climate Change (IPCC), wind and solar power generation will only drop slightly. 

<a href="http://www.earth.com/news/humans-driving-climate-change/">Climate change</a> will increase the amount of cloud cover above northern Europe As a result, solar panels will generate less power. There will also be an increase in the frequency of storms, interfering with the energy produced by wind turbines, which automatically shut down during storms.

According to the researchers, more energy is used for heating than cooling in Europe. This means that energy demand will decrease as temperatures rise and will balance out the drop in wind and solar power generation.

Jim Watson is a professor of Energy Policy at University College London who was not involved in the study. Professor Watson told <a href="https://www.newscientist.com/">New Scientist</a> that the research “provides some confidence about the resilience of a low carbon electricity system.”

“Extreme weather might require changes to the renewable generators and other parts of the system,” said Kozarcanin. “For example, future wind turbines may require new types of storm protection and solar panels could need protection against super hailstorms. But our study shows that large-scale infrastructure choices, such as back-up power plant capacity, are relatively unaffected by the level of climate change.”

The study is published in the journal <a href="https://www.cell.com/joule/home">Joule</a>.

New research has revealed just how much <a href="https://www.earth.com/news/smoking-leads-poor-diet/">smoking</a> can drastically speed up the aging process in adults.

According to scientists, people actually have two ages, their chronological age and their biological age. Chronological, as the name suggests, is your age according to when you were born, but biological age refers to the age of a person’s body based on different biological markers and lifestyle factors.

Two people may be chronologically the same age, but have very different biological ages based on lifestyle, diet, and age-related disease risks. 

Researchers from <a href="http://insilico.com/">Insilico Medicine</a>, an artificial intelligence solutions company, conducted a study to examine the impact smoking has on biological age. 

The study was published in the journal Scientific Reports and results show that smoking can increase a person’s biological age as much as 20 years. 

The researchers reviewed and analyzed a large dataset meant to represent the entire population of Alberta, Canada including both rural and urban populations. The dataset was comprised on 149,000 individual records and of those 49,000 were smokers. 

Blood biochemistry and cell count information on non-smokers and smokers was then fed into a deep neural network, an advanced algorithm and modeling system, which had been trained to predict the chronological age of an individual based on the blood data.

The researchers first predicted that the biological age of smokers under 30 would be anywhere between 31 to 50. 

After the deep neural network analyzed the data, biological age for smokers 31 to 40 years of age was predicted to be 41 to 50. 

“Compared with nonsmokers, smokers showed an accelerated rate of aging through to age 55 years regardless of sex,” the researchers <a href="https://www.nature.com/articles/s41598-018-35704-w">said</a>. 

Older smokers did not have as drastic differences in their ages. 

Analysis of blood tests could soon replace traditional self-reporting methods that medical professionals use to measure the health impacts of different lifestyle choices, according to the <a href="https://www.dailymail.co.uk/health/article-6603459/Smoking-AGES-Scientists-discover-40s-biologically-TWICE-age.html">Daily Mail</a> which reported on the study. 

“We applied artificial intelligence to prove that smoking significantly increases your biological age,” said Polina Mamoshina, the lead author of the study. “I am pleased to be part of the research study, which provides fascinating scientific evidence that smoking is likely to accelerate ageing.”

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."

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."

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



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



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



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



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