As the days count down to NASA's OSIRIS-REx spacecraft's Touch-And-Go asteroid sample collection attempt, scientists have determined what the spacecraft can expect to return from the near-Earth asteroid Bennu's surface. Three papers discuss the color, reflectivity, age, composition, origin and ...

Researchers successfully print and demonstrate organic transistors, electronic switches, which can operate close to their theoretical speed limits. They showed high-speed operation only requires low voltages to work, which would reduce the power consumption of their applications. These kinds of ...
