A study suggests that Homo sapiens may have benefited from the use of ochre and tailored clothing during a period of increased UV light 41,000 years ago, during the Laschamps excursion.

Scientists find evidence that overturns theories of the origin of water on Earth
Researchers have helped overturn the popular theory that water on Earth originated from asteroids bombarding its surface; Scientists have analyzed a meteorite analogous to the early Earth to understand the origin of hydrogen on our planet. The research team demonstrated that the material which built our planet was far richer...
Secret to crocodylian longevity
Researchers examined teeth and skulls of 99 extinct crocodylomorph species and 20 living crocodylian species to reconstruct their dietary ecology and identify characteristics that helped some groups persist through two mass extinctions. They discovered that one secret tocrocodylian longevity is their remarkably flexible lifestyles, both in what they eat and...
New giant virus isolated
Researchers have isolated a giant virus, which was named Jyvaskylavirus. The discovery shows that giant viruses are more common in northern regions than researchers have thought. It also illustrates that there are still many structures whose origins and functions have not been properly studied.
New Study Reveals How to Make Prescribed Forest Fires Burn Safer and Cleaner
Scientists estimate that tweaking some burn conditions could cut cancer risks from smoke exposure by over 50%.
AI Finds New Ways to Observe the Most Extreme Events in the Universe
Extreme cosmic events such as colliding black holes or the explosions of stars can cause ripples in spacetime, so-called gravitational waves.
Scalable Graphene Membranes: A Leap for Carbon Capture
Scientists at EPFL have developed a scalable method to produce porous graphene membranes that efficiently separate carbon dioxide.
Growing wildflowers on disused urban land can damage bee health
Wildflowers growing on land previously used for buildings and factories can accumulate lead, arsenic and other metal contaminants from the soil, which are consumed by pollinators as they feed, a new study has found.
Gut microbes release cancer-fighting bile acids that block hormone signals
Bacteria naturally present in the human intestine (known as the gut microbiota) can transform cholesterol-derived bile acids into powerful metabolites that strengthen anti-cancer immunity by blocking androgen signaling, according to a preclinical study.
Can citizen science be trusted? New study of birds shows it can
Platforms such as iNaturalist and eBird encourage people to observe and document nature, but how accurate is the ecological data that they collect? A new study shows that citizen science data from iNaturalist and eBird can reliably capture known seasonal patterns of bird migration in Northern California and Nevada --...
