Space weather forecasting needs an upgrade to protect future Artemis astronauts
NASA has set its sights on the moon, aiming to send astronauts back to the lunar surface by 2026 and establish a long-term presence there by the 2030s. But the moon isn't exactly a habitable place for people......»»
How a single atomic sensor can help track Earth"s glaciers
Earth observations are one of the most essential functions of our current fleet of satellites. Typically, each satellite specializes in one kind of remote sensing—monitoring ocean levels, for example, or watching clouds develop and move. That is pr.....»»
Scientists propose distance-based visual miRNA biosensor
Point-of-care testing (POCT) devices show great advantages over conventional diagnostic tests in being accessible to patients and providing timely diagnostic information. The global POCT market has grown remarkably over the past few decades. Distance.....»»
