Phys.org / Amplifying feedbacks could drive Greenland ice sheet to near-complete disappearance

Greenland, which has been prominently in the news in recent days, hosts a vast ice sheet. If it melts, it will become one of the largest contributors to global sea-level rise. Under a high-emissions scenario, the Greenland ...

Phys.org / Four-eyed Cambrian fish fossils hint at origins of vertebrate pineal complex

New fossil evidence from China suggests that some of our vertebrate ancestors had four eyes. The study, published in Nature, takes a closer look at a structure found in multiple 518 million-year-old fossils, which appears ...

Phys.org / Chimpanzees are better at solving resource dilemmas in larger, more tolerant groups

Despite being one of the most cooperative species on the planet, humans routinely fail to manage shared resources sustainably. We overfish from the oceans, burn fossil fuels, and over-prescribe antibiotics; behaviors that ...

Phys.org / Ancient giant kangaroos could hop to it when they needed to, hindlimb study suggests

Giant ancestors of modern-day kangaroos—which previous research has estimated could weigh up to 250 kilograms—may have been able to hop in short bursts, according to research published in Scientific Reports.

Phys.org / Rethinking where life could exist beyond Earth

Astronomers have long searched for life within a rather narrow ring around a star, the "habitable zone," where a planet should be neither too hot nor too cold for liquid water. A new study argues that this ring is too strict: ...
