An interdisciplinary team of researchers has created an open-source website to learn what different organisms eat, and what eats them. The site – called Who Eats Whom – draws on data from a worldwide citizen science platform and serves as both a valuable resource for ecological research and an educational tool to advance public understanding of the global food web.

Loneliness and social isolation are linked to a range of serious health problems, but their overall toll on healthy life has been hard to quantify until now. In a first-of-its-kind study published in Nature Communications, Tulane University researchers analyzed data from 277,489 UK Biobank adults tracked for more than a decade. They found men experiencing both loneliness and social isolation lost up to six years free from depression and anxiety. Women, meanwhile, lost roughly four fewer years.

Drivers were less likely to wear seatbelts at night, at higher speeds and on shorter trips, suggesting safety campaigns may be more effective when they target the situations in which people are most likely to skip buckling up.
