The study, which explores how particulate pollution impacts the adolescent brain, involves 10,000 youth and is among the first of its kind. According to a recent study by the University of Colorado Boulder, which analyzed 10,000 children aged 9 to 11, each additional day of exposure to wildfire smoke and other severe air pollutants slightly increases the risk of mental health issues in young people. “We found that a greater number of days with fine particulate air pollution levels above EPA standards was associated with increased symptoms of mental illness, both during the year of exposure and up to one...

Kamala Harris and the Democrats have gone strangely silent about the “climate crisis” they warned was an existential threat a few years ago.. Don’t look now, but the “climate crisis” is officially over. No need to take my word for it. Just ask the Democratic Party’s new standard bearer, Vice President Kamala Harris, who mentioned the topic “just once” in her acceptance speech at the recent Democratic National Convention, according to The New York Times. The Times also noted that Harris “has not offered any new policies for addressing climate change.” How far we have come in five short years....

New research reveals that discrepancies between the locations where fossils are found and the areas where early humans are thought to have resided could affect our comprehension of human evolutionary history.A significant portion of the early human fossil record comes from a few key locations in Africa, where ideal geological conditions have preserved a wealth of fossils that scientists use to piece together the story of human evolution. One notable area is the eastern branch of the East African Rift System, which includes important fossil sites like Oldupai Gorge in Tanzania.Yet, the eastern branch of the rift system only accounts...

Pope Francis calls for Catholics to ‘pray for the cry of the Earth,’ says it ‘has a fever’‘We pray that each of us will listen with the heart to the cry of the Earth,’ Pope Francis said in a new video, claiming that ‘if we took the planet’s temperature, it will us that the Earth has a fever. And it is sick, just like anyone who’s sick.’Pope Francis calls for ecological concern in his Pope Video.This September, Pope Francis has urged members of the Catholic Church to “pray for the cry of the Earth” and “the victims of environmental disasters...

Imperial College London research has found limits to how quickly we can scale up technology to store gigatonnes of carbon dioxide under Earth's surface. Current international scenarios for limiting global warming to less than 1.5 degrees by the end of the century rely on technologies that remove carbon dioxide (CO2) from Earth's atmosphere faster than humans release it. This means removing CO2 at a rate of 1–30 gigatonnes per year by 2050. However, estimates for the speed at which these technologies can be deployed have been highly speculative. Now, findings from a new study led by Imperial College London researchers...

WASHINGTON) -- Climate change may not be a top concern for voters for the 2024 presidential election, but that hasn't stopped many Republicans from making misrepresentations about environmental and energy policy – a departure from the previous tactic of majority climate change denial, according to experts on environmental politics who spoke with ABC News. Debates around energy policy, specifically regarding renewable energy versus fossil fuels, are inherently connected to climate change, in large part because fossil fuels are the largest contributor to climate change, according to the United Nations, accounting for more than 75% of global greenhouse gas emissions and...

Highlighting seas that are rising at an accelerating rate, especially in the far more vulnerable Pacific island nations, U.N. Secretary-General Antonio Guterres issued yet another climate SOS to the world. This time he said those initials stand for “save our seas.” The United Nations and the World Meteorological Organization Monday issued reports on worsening sea level rise, turbocharged by a warming Earth and melting ice sheets and glaciers. They highlight how the Southwestern Pacific is not only hurt by the rising oceans, but by other climate change effects of ocean acidification and marine heat waves. Guterres toured Samoa and Tonga...

For over a year, surface temperatures in the Atlantic Ocean hit new highs, but that trend has reversed at record speed over the past few months, and nobody knows why. {skip obligatory global warming bs next few paragraphs...} NOAA data shows Atlantic sea surface temperatures have cooled at a surprising rate since May. Since June began, temperatures have been a degree or two Fahrenheit colder than normal for this time of year. That means El Niño will likely be replaced by its counterpart, La Niña, a weather system that allows cold water to rise to the surface of the Atlantic,...

The Turin Shroud has been at the center of debate for centuries with many believing it was the cloth used to wrap Jesus's body after the crucifixion. ====================================================================== Scientists are inching closer to determining whether the famed Turin Shroud is indeed the cloth in which Jesus was wrapped. Experts have now stated that the linen can be traced back to the beginning of the AD era, aligning with the time when Jesus was crucified. The shroud, which bears a faint outline of a bearded man believed to be an imprint left by Jesus's body, was first displayed in 1350 and...

Anne Fausto-Sterling s suggestion that the prevalence of intersex might be as high as 1.7% has attracted wide attention in both the scholarly press and the popular media. Many reviewers are not aware that this figure includes conditions which most clinicians do not recognize as intersex, such as Klinefelter syndrome, Turner syndrome, and late-onset adrenal hyperplasia. If the term intersex is to retain any meaning, the term should be restricted to those conditions in which chromosomal sex is inconsistent with phenotypic sex, or in which the phenotype is not classifiable as either male or female. Applying this more precise definition,...

The carvings at Göbekli Tepe even show the movements of the constellations. Image credit: Dr Martin Sweatman Acataclysmic comet impact 13,000 years ago may have sparked the rise of civilization, according to the authors of a new study. The event – which many scientists believe never happened – may even be documented at the world-famous site of Göbekli Tepe, forming part of a series of carvings that the researchers say represent the world’s oldest solar calendar. Located in southern Türkiye, Göbekli Tepe is a pre-pottery Neolithic complex that is estimated to be around 12,000 years old. Analyzing an intricately carved...

he importance of high-quality mask-wearing cannot be overstated in the ongoing battle against airborne threats like viruses, wildfire smoke, and environmental particles. Jennifer Veltman, MD, chair of infectious diseases, outlines the times to wear a mask in 2024

Scientists have claimed that the consumption of the fungi psilocybin, also known as 'magic mushrooms,' influenced pre-human hominids' brains six million years ago.They analyzed dozens of studies involving psilocybin and consciousness, finding the fungi increased connectivity between networks in the frontal brain region associated with expressive language, decision-making and memory.These 'significant neurological and psychological effects' may have been the catalase ancient ancestors to interact with each other and the environment - spurring consciousness among our species.The idea that magic mushrooms sparked the pivotal point in humans has been touted by podcaster Joe Rogan, who has referenced the 'Stoned Ape Theory'...

Prehistoric humans hunt a woolly mammoth. More and more research shows that this species – and at least 46 other species of megaherbivores – were driven to extinction by humans. Credit: Engraving by Ernest Grise, photographed by William Henry Jackson. Courtesy Getty’s Open Content Program ================================================================== Researchers at Aarhus University have concluded that human hunting, rather than climate change, was the primary factor in the extinction of large mammals over the past 50,000 years. This finding is based on a review of over 300 scientific articles. Over the last 50,000 years, many large species, or megafauna, weighing at least 45...

The discovery of butchered bones belonging to a glyptodont, a giant relative of the armadillo, suggests that humans were living in Argentina 20,000 years ago. Ancient humans may have butchered and eaten a giant armadillo-like creature around 20,000 years ago in what is now Argentina, a new study finds. The discovery of the butchered bones supports a growing body of evidence that people spread throughout the Americas much earlier than previously assumed. During the Late Pleistocene epoch (129,000 to 11,700 years ago), ice sheets and glaciers covered much of the planet, particularly during the Last Glacial Maximum, a period around...

The impacts of human-caused climate change are so overwhelming they’re actually messing with time, according to new research. Polar ice melt caused by global warming is changing the speed of Earth’s rotation and increasing the length of each day, in a trend set to accelerate over this century as humans continue to pump out planet-heating pollution, according to the study published Monday in the Proceedings of the National Academy of Sciences. The changes are small — a matter of milliseconds a day — but in our high-tech, hyperconnected world have an important impact on computing systems we have come to...

People also often try to simply change the topic of conversation. Image credit: zeljkodan/Shutterstock.com ================================================================== Eating too much meat is bad for you, bad for the environment, and fatal for the animals involved. Those are straight facts, indisputable and proven through years of study. But counterpoint: have you considered that vegans are annoying? If the comments section under just about any media promoting a vegetarian or vegan diet is anything to go by, the answer to that question is probably “yes”. And, in any case, what about all the poor plants, huh? You okay with murdering them, IFLScience? The blood...

As a vocal advocate of vaccinations for public health, Peter Hotez was no stranger to online harassment and threats. But then the abuse showed up on his doorstep. It was a Sunday during a brutal Texas heatwave in June 2023 when a man turned up at Hotez’s home, filming himself as he shouted questions at the scientist, who is a paediatrician and virologist at Baylor College of Medicine in Houston, Texas. Because of the long-running online and real-life abuse he has faced, Hotez now has the Texas Medical Center Police, Houston Police Department and Harris County Sheriff’s Office on speed...

Fake studies have flooded the publishers of top scientific journals, leading to thousands of retractions and millions of dollars in lost revenue. The biggest hit has come to Wiley, a 217-year-old publisher based in Hoboken, N.J., which Tuesday will announce that it is closing 19 journals, some of which were infected by large-scale research fraud.
