To discover new physics, AI may need to 'unlearn' the old one

A major study suggests glucosamine, a popular supplement for joint pain, could be linked to faster progression from mild cognitive impairment to Alzheimer’s disease. Researchers found a 25% higher likelihood of developing dementia among glucosamine users and uncovered biological clues that may explain why.

Earth’s earliest animals may have held evolution back because they reproduced asexually, creating low-competition communities that changed very little over time. When environmental pressures pushed them toward sexual reproduction, biodiversity exploded and evolution accelerated dramatically.

Ice splintered off the southern Patagonia glacier and drifted across a growing glacial lake.

Lesser black-backed gulls from the colony on the Dutch island of Neeltje Jans appear to avoid the wind farm off the Zeeland coast, with the exception of some males. NIOZ ecologist Rosemarie Kentie and her colleagues suspected the gulls were attracted by fishing boats outside the wind farm and the bycatch thrown overboard. This turned out not to be the case: Even during weekends, when there is little fishing, the birds rarely visit the wind farm.
