Identifying the favorite snacks of one of Australia's cutest animals no longer needs to rely on guesswork or picking apart their poop, according to University of the Sunshine Coast research. Although the shortened title of her latest paper is "The future is faeces," associate professor Dominique Potvin and colleagues want to make the task less of a hands-on, hit-and-miss job.

High-resolution global atmospheric model erases 'popcornlike' rain
Global climate and weather forecasting use predictive models that divide Earth's atmosphere into a grid, with each section typically covering tens to hundreds of kilometers. Now a new model, run by a team at the University of Tokyo, has narrowed this grid spacing to just 220 mete

Scientists discover a human brain gene that can jump through DNA
Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a mobile piece of DNA known as a trans

Electrons slow to a crawl in a strange new quantum state
Scientists at the University of Chicago have uncovered a surprising quantum state in the layered magnetic material Fe5GeTe2, where huge numbers of electrons move together unusually slowly while remaining quantum coherent. The behavior contradicts existing theoretical predictions

One tiny chemical difference between RNA and DNA may help explain how life began
Scientists may have found a clue to one of the biggest mysteries surrounding the origin of life: how fragile RNA molecules could gather and survive before cells existed. New research shows that RNA is unusually good at assembling into tiny liquid-like droplets that concentrate mo
