Wearable tech for space station research

Many of us wear devices that count our steps, measure our heart rate, track sleep patterns, and more. This information can help us make healthy decisions—research shows the devices encourage people to move more, for example—and ...

Flagship AI-ready dataset released in type 2 diabetes study

Researchers are releasing the flagship dataset from an ambitious study of biomarkers and environmental factors that might influence the development of type 2 diabetes. Because the study participants include people with no ...

Scientists in Japan develop new SARS-CoV-2 variant detection method

Researchers at Kumamoto University have made a significant breakthrough in the fight against COVID-19 with the development of "Intelli-OVI," a cutting-edge diagnostic tool capable of rapidly identifying emerging variants ...

Astronomers discover a new repeating fast radio burst

Using the CHIME telescope, an international team of astronomers has detected a new repeating fast radio burst (FRBs) source in the outskirts of a quiescent galaxy. The finding of a new FRB, which experienced 22 repeating ...
