Phys.org / Were Clovis foragers in Late Pleistocene North America big-game hunters, or just big-game scavengers?

There are currently 15 well-documented Late Pleistocene localities in North America in which Clovis points are found associated with proboscidean remains (of mammoth, mastodon and gomphothere). Archaeologists routinely assume ...

Phys.org / Acceptor molecule upconverts low-energy green light to high-energy purple with high efficiency

Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply ...

Phys.org / Ancient gum disease may have helped reshape jaws before human brains expanded

Human evolution is generally explained through changes in brain size, locomotion or tool use, but new research from Wits University suggests that gum disease and changes in facial structure may have been important factors ...

Phys.org / Primate brains might have evolved to 'catch up' with larger bodies, but then kept growing

A new analysis supports the previously overlooked "brain lag" hypothesis—the idea that, in some primate lineages, the evolution of larger body size preceded the evolution of larger brain size—while also building on that hypothesis ...

Phys.org / Webb reveals merger scars in galaxies that stopped forming stars 9 billion years ago

Research has shed new light on why some distant galaxies suddenly stop forming stars. An international team led by astronomers at the University of Nottingham has used the James Webb Space Telescope to study a large sample ...
