NASA rocket chasing the source of the sun's hot atmosphere

After glimpsing faint but widespread super-heated material in the Sun's outer atmosphere, a NASA sounding rocket is going back for more. This time, they're carrying a new instrument optimized to see it across a wider region ...

Blue light means big progress for perovskite-based LEDs

Researchers at Linköping University, Sweden, have developed efficient blue light-emitting diodes based on halide perovskites. "We are very excited about this breakthrough," says Feng Gao, professor at Linköping University. ...

Stellar heavy metals can trace history of galaxies

Astronomers have cataloged signs of nine heavy metals in the infrared light from supergiant and giant stars. New observations based on this catalog will help researchers to understand how events like binary neutron star mergers ...

Polluted wastewater in the forecast? Try a solar umbrella

Evaporation ponds, which are commonly used in many industries to manage wastewater, can span acres, occupying a large footprint and often posing risks to birds and other wildlife. Yet they're an economical way to deal with ...

Chip-based optical sensor detects cancer biomarker in urine

For the first time, researchers have used a chip-based sensor with an integrated laser to detect very low levels of a cancer protein biomarker in a urine sample. The new technology is more sensitive than other designs and ...
