A simulation of electrons at different energies scattering off atomic defects like those in samarium hexabroide. By observing such waves, the researchers measured the electron’s energy and momentum to discover the tell-tale signature of a topological state.

Diagram with the stages of the study. The main ommochrome identified in squid skin is xanthommatin. Credit: Chan-Higuera et al. Ommochromes, the pigments that colour the skin of squids and other invertebrates, could be used in the food and health sectors for their antioxidant and antimicrobial properties. This is confirmed by analyses carried out by

An illustration of the changes observed in the skulls of different groups of herbivorous dinosaurs. Credit: Button and Zanno, Current Biology Herbivorous dinosaurs evolved many times during the 180 million-year Mesozoic era, and while they didn’t all evolve to chew, swallow, and digest their food in the same way, a few specific strategies appeared time

From 1861 to 1865, the Civil War tore the United States asunder. But while the country may have been consumed by conflict, new research suggests soldiers off the battlefield still made time for a wee bit of vanity. Archaeological excavations at Camp Nelson—a former Union outpost in central Kentucky—have unearthed broken bottles that once held

In a cleanroom in Ottobrunn, Germany, the latest Copernicus Sentinel satellite is ready for final testing before it is packed up and shipped to the US for liftoff next year. Designed and built to chart changing sea level, it is the first of two identical Sentinel-6 satellites that will be launched consecutively to continue the

A research team has reported seeing, for the first time, atomic scale defects that dictate the properties of a new and powerful semiconductor. The study, published earlier this month in the journal Physical Review X, shows a fundamental aspect of how the semiconductor, beta gallium oxide, controls electricity. “Our job is to try to identify

WASHINGTON — NASA space station managers are still trying to find ways to squeeze in at least three spacewalks into a crowded schedule before the station’s crew drops to three people in February. NASA astronaut Andrew Morgan and ESA astronaut Luca Parmitano completed the third in a series of spacewalks Dec. 2 to repair the

There are plenty of apple varieties available on grocery shelves nowadays, and we all have our preferences. Some might favor the sharp and tangy Granny Smith, for instance, while others prefer the sweet and juicy MacIntosh. But scientists, growers and industry experts are banking on everyone loving their latest creation: a hybrid apple that proponents
