New Mineral

NASA researchers and scientists from the United States, Germany and Japan have found a new mineral in material they believe came from a comet. The mineral, a manganese silicide named Brownleeite, was discovered within an interplanetary dust particle, or IDP, that appears to have originated from comet 26P/Grigg- Skjellerup. The comet...

Low-Power Microchip

A new low-power microchip developed at the University of Michigan uses 30,000 times less power in sleep mode and 10 times less in active mode than comparable chips currently on the market. The Phoenix Processor, as it's called, sets a low-power record and is intended for use in cutting-edge sensor-based devices such as...

Super-Earths

Using the HARPS instrument at the ESO La Silla Observatory, European astronomers have found a system of three super-Earths around the star HD 40307 - a breakthrough in the field of extra-solar planets. The astronomers also counted a total of 45 candidate planets with a mass below 30 Earth masses and an orbital period shorter than 50...
