Your fingers may hold a secret of human brain evolution

Human evolution is closely associated with the development of a much larger brain. New research suggests that greater exposure to estrogen before birth may have contributed to that expansion, and that a possible trace of this hormonal influence can be seen in the relative lengths of a person’s fingers.

Koalas nearly went extinct before humans arrived, DNA study reveals

A major genomic analysis is changing scientists’ understanding of koala evolution. The research indicates that koalas (Phascolarctos cinereus) underwent a severe population decline about 100,000 years ago, well before humans reached Australia. Every koala alive today appears to descend from a single ancestral population that endured dramatic environmental shifts, including…

Scientists tested 39 sweeteners and found unexpected gut effects

The strongest effect appeared when researchers combined isosteviol, a sweetener used by the food and beverage industry, with the antidepressant duloxetine. Together, the two…

Scientists built a camera that can track invisible particles in 3D

Some breakthroughs in physics come from brand new inventions. Others begin with a new theory. But many advances happen when researchers combine familiar technologies in an unexpected way and create something more powerful than the individual parts. That strategy could be especially valuable in the search for weakly interacting particles,…

New Alzheimer's drug repairs DNA damage and reduces brain inflammation

Researchers at King’s College London have identified a promising new strategy for tackling Alzheimer’s disease by targeting several of the disease’s earliest biological changes at the same time. Their study found that KCL-286, an experimental drug originally developed for spinal cord injury that has already passed Phase 1 safety trials,…
