Scientists have discovered that a gene called MUC19, inherited from Denisovans through ancient interbreeding, may have played a vital role in helping Indigenous ancestors adapt as they migrated into the Americas. Found at unusually high frequencies in both modern and ancient populations, the gene likely provided immune advantages against new...
Scientists unlock nature’s secret to superfast mini robots
Ripple bugs’ fan-like legs inspired engineers to build the Rhagobot, a tiny robot with self-morphing fans. By mimicking these insects’ passive, ultra-fast movements, the robot gains speed, control, and endurance without extra energy—potentially transforming aquatic microrobotics.
Why tiny bee brains could hold the key to smarter AI
Researchers discovered that bees use flight movements to sharpen brain signals, enabling them to recognize patterns with remarkable accuracy. A digital model of their brain shows that this movement-based perception could revolutionize AI and robotics by emphasizing efficiency over massive computing power.
Most of Earth’s species came from explosive bursts of evolution
A new study reveals that the majority of Earth’s species stem from a few evolutionary explosions, where new traits or habitats sparked rapid diversification. From flowers to birds, these bursts explain most of the planet’s biodiversity.
Scientists found the missing nutrients bees need — Colonies grew 15-fold
Scientists have developed a breakthrough food supplement that could help save honeybees from devastating declines. By engineering yeast to produce six essential sterols found in pollen, researchers provided bees with a nutritionally complete diet that boosted reproduction up to 15-fold. Unlike commercial substitutes that lack key nutrients, this supplement mimics...
The Rise of Plant Life Changed How Rivers Move, Study Shows
Research reveals that unvegetated meandering rivers can geologically masquerade as braided rivers, suggesting they were much more common in the first 90 percent of Earth’s history than previously thought.
Ecology Professor Explores How and Why Forests Change
Almost everything Nina Wurzburger does — at least in terms of research — relates to forests.
Nature Could Be an Effective Self-Help Tool for Improving Mental Health
Engaging with nature could be an effective measure for those with low wellbeing to reduce symptoms of depression and anxiety.
Hidden venom divide in Australia’s deadliest snake raises urgent treatment questions
Scientists have uncovered a startling split in the venom of Australia’s Eastern Brown Snake. In the south, bites cause rock-solid blood clots, while in the north, they trigger flimsy clots that collapse almost instantly. This hidden divide means current antivenoms, made from pooled venom of uncertain origin, may not work...
Ozone recovery could trigger 40% more global warming than predicted
As the ozone layer recovers, it’s also intensifying global warming. Researchers predict that by 2050, ozone will rank just behind carbon dioxide as a driver of heating, offsetting many of the benefits from banning CFCs.
