Researchers create switchable mirrors from liquid metal

Researchers have developed a way to dynamically switch the surface of liquidmetal between reflective and scattering states. This technology could one day be used to create electrically controllable mirrors or illumination ...

Inside the Irish lough that offers a window into the deep sea

Deeper than most scuba divers can safely work and above where most underwater robots are designed to descend lie some of the most poorly studied ecosystems in the world. Between 30 and 150 meters down is the ocean's mesophotic ...

White dwarf stars' debris disk formation delayed

White dwarfs, the glowing cores of dead stars, often host disks of dusty debris. However, these debris disks only appear 10 to 20 millions of years following the star's violent Red Giant phase. A new paper by Planetary Science ...

World's lakes losing oxygen rapidly as planet warms

Oxygen levels in the world's temperate freshwater lakes are declining rapidly—faster than in the oceans—a trend driven largely by climate change that threatens freshwater biodiversity and drinking water quality.

Air quality improved during India lockdown, study shows

Research by scientists from University of Southampton (UK) and the Central University of Jharkhand (India) has shown the first COVID-19 lockdown in India led to an improvement in air quality and a reduction in land surface ...

Satellites may have underestimated warming in the lower atmosphere

New research by Lawrence Livermore National Laboratory (LLNL) climate scientists and collaborators shows that satellite measurements of the temperature of the troposphere (the lowest region of the atmosphere) may have underestimated ...
