Phys.org / Lost mosaic reveals first image of female beast-fighter from the Roman era

When you think of a fight between an animal and a human in ancient Roman sports, the mental image is usually of a big man vs. an animal in a big arena filled with cheering spectators. In a new study, Alfonso Manas, a researcher ...

Phys.org / SimCells successfully target and kill drug-resistant bacteria

We are continually in an evolutionary arms race with bacteria. As we develop new antibiotics, they develop resistance, and so it goes on until some of our treatments no longer work. Superbugs and antimicrobial resistance ...

Phys.org / Great hammerheads maintain peak hunting across wide temperature swings, biologging data suggest

Most predators slow down when ocean temperatures shift. Great hammerhead sharks don't—not significantly anyway. These ocean predators are masters of the "thermal hustle," maintaining peak hunting performance across a surprisingly ...

Phys.org / Physicist recreates neutron star reaction, reveals how explosive stars forge elements

A Mississippi State physicist has produced a direct laboratory measurement of a key nuclear reaction believed to occur during explosive bursts on neutron stars. These bursts forge heavier elements—the building blocks of planets ...

Phys.org / Chiral metasurfaces guide twisted light into free space

Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can twist like a corkscrew ...
