Intakes of dietary fiber and high-quality carbohydrates in midlife are linked to increased likelihood of healthy aging and other positive health outcomes in older women. Higher intakes of refined carbohydrates and starchy vegetables were associated with lower odds of healthy aging. Newly discovered weapons of bacterial self-defense take different approaches to achieving the same goal: preventing …

Wealthy individuals have a higher carbon footprint. A new study quantifies the climate outcomes of these inequalities. It finds that the world's wealthiest 10% are responsible for two thirds of observed global warming since 1990 and the resulting increases in climate extremes such as heatwaves and droughts. Wild chimpanzees alter the meaning of single calls when embedding them into diverse call c…

Humans are better than current AI models at interpreting social interactions and understanding social dynamics in moving scenes. Researchers believe this is because AI neural networks were inspired by the infrastructure of the part of the brain that processes static images, which is different from the area of the brain that processes dynamic social scenes. A landmark study reveals that a single o…

Rsearchers have developed the first wearable device for measuring gases emitted from and absorbed by the skin. By analyzing these gases, the device offers an entirely new way to assess skin health, including monitoring wounds, detecting skin infections, tracking hydration levels, quantifying exposure to harmful environmental chemicals and more. Astronomers are investigating the longest and most e…

New research has found that employers and policymakers might want to start paying attention to how workers are feeling, because employee happiness contains critical economic information. Cold water immersion for seven days significantly improves cellular resilience and autophagic function, helping cells manage stress better. This adaptation could enhance health and longevity, potentially preventi…

A sweeping study for the first time tallies butterfly data from more than 76,000 surveys across the continental United States. The results: Butterflies -- all of them -- are disappearing. Until now, artificial gels have either managed to replicate high stiffness or natural skin's self-healing properties, but not both. Now, a team of researchers has developed a hydrogel with a unique structure tha…

Researchers have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study shows that the pupil is smallest during inhalation and largest during exhalation -- something that could affect our vision. Thank you to our 3D printing sponsors at Toybox! Toybox makes 3D printing fun and easy for kids! Young creators can bring ideas to life with a vast project…

Humanity may not be extraordinary but rather the natural evolutionary outcome for our planet and likely others, according to a new model for how intelligent life developed on Earth. The clownfish-anemone living arrangement is one of the most widely recognized examples of symbiosis. Researchers have made a breakthrough in understanding how anemonefish can live safely among sea anemones without bei…

A new study focusing on Enceladus, a moon of Saturn, shows that the physics of alien oceans could prevent evidence of deep-sea life from reaching places where we can detect it. Based on the current pledges of countries for limiting their emissions of greenhouse gases, global temperatures are projected to reach 2.7 degrees Celsius beyond pre-industrial levels by the end of this century. A new revi…

Your parents were right: Scratching an itchy rash really does make it worse. Now we know why, thanks to new research that uncovers how scratching aggravates inflammation and swelling in a mouse model of a type of eczema called allergic contact dermatitis. Some biologists speculate that animals will get smaller with global warming to reduce heat stress. While this may be true of warm-blooded anima…

Researchers have developed a way of bioprinting tissues that change shape as a result of cell-generated forces, in the same way that it happens in biological tissues during organ development. The breakthrough science focused on replicating heart tissues, bringing research closer to generating functional, bioprinted organs, which would have broad applications in disease modelling, drug screening a…

People who eat more red meat, especially processed red meat like bacon, sausage and bologna, are more likely to have a higher risk of cognitive decline and dementia when compared to those who eat very little red meat, according to a new study. In the years following the launch of NASA's Hubble Space Telescope, astronomers have tallied over 1 trillion galaxies in the universe. But only one galaxy …

The way cricket frogs move across the surface of water has long been thought to resemble walking on water, but researchers have now discovered a different reality. A whitish, grey patch that sometimes appears in the night sky alongside the northern lights has now been explained. A new study has found that the composition of your gut microbiome helps predict how likely you are to succumb to potent…

A research team has developed a method for extracting gold from electronics waste, then using the recovered precious metal as a catalyst for converting carbon dioxide (CO2), a greenhouse gas, to organic materials. Image: Matt Benoit/Shutterstock.com Scientists recently discovered that the giant 'conveyer belt' currents that push star-forged material out of our galaxy and pull it back in can also …

A new study has provided further evidence that the deaths of 350 African elephants in Botswana during 2020 were the result of drinking from water holes where toxic algae populations had exploded due to climate change. Image: Shutterstock.com Coral adaptation to ocean warming and marine heatwaves will likely be overwhelmed without rapid reductions of global greenhouse gas emissions, according to a…

Researchers have discovered evidence of the oldest alphabetic writing in human history. The writing was etched onto clay cylinders discovered during a dig at an ancient Syrian city. Image: Mulad Images/Shutterstock.com Geneticists have developed a gene drive-based solution to the widespread problem of insecticide resistance. In an effort to protect valuable crops, the researchers created an 'e-Dr…

Researchers have used artificial intelligence to design thousands of new DNA switches that can precisely control the expression of a gene in different cell types. Their new approach opens the possibility of controlling when and where genes are expressed in the body, for the benefit of human health and medical research, in ways never before possible.

A new study reveals how the duplication of the salivary amylase gene may not only have helped shape human adaptation to starchy foods, but may have occurred as far back as more than 800,000 years ago, long before the advent of farming. Image: Gaidamashchuk/Shutterstock.com Physicists have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These ax…
