Scientists identify 2022 sea urchin killer

The mass die-off of the long-spined sea urchin – a loss that threatens the health of coral reefs from the Caribbean to Florida’s east coast — was caused by a…

Polar ice sheet melting records have toppled during the past decade

The seven worst years for polar ice sheets melting and losing ice have occurred during the past decade, according to new research, with 2019 being the worst year on record….

“Berlin Statement” to protect polar regions from pollutants

The polar regions are exposed to an increasing load of pollutants. Under the leadership of the Helmholtz-Zentrum Hereon and the Umweltbundesamt (UBA), experts from the European Commission, the Stockholm Convention,…

X-rays reveal electronic details of nickel-based superconductors

Findings show similarities to and differences from cuprate superconductors, including more complex electronic structure. Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have discovered new details about…

Four-legged robotic system that can walk a balance beam

Spacecraft-inspired system enhances quadruped agility and balance. Researchers in Carnegie Mellon University’s Robotics Institute (RI) have designed a system that makes an off-the-shelf quadruped robot nimble enough to walk a narrow balance beam —…

Backscattering protection in integrated photonics

… is impossible with existing technologies. DTU researchers raise fundamental questions about the proposed value of topological protection against backscattering in integrated photonics. The field of integrated photonics has taken…
