| NASA's WISE mission captures black hole's wildly flaring jet Posted: 20 Sep 2011 01:15 PM PDT Astronomers using NASA's Wide-field Infrared Survey Explorer (WISE) have captured rare data of a flaring black hole, revealing new details about these powerful objects and their blazing jets.  |
| Microwave ovens a key to energy production from wasted heat Posted: 20 Sep 2011 09:02 AM PDT More than 60 percent of the energy produced by cars, machines, and industry around the world is lost as waste heat -- an age-old problem -- but researchers have found a new way to make "thermoelectric" materials for use in technology that could potentially save vast amounts of energy.  |
| Proton-based transistor could let machines communicate with living things Posted: 20 Sep 2011 08:18 AM PDT Human devices, from light bulbs to iPods, send information using electrons. Human bodies and all other living things, on the other hand, send signals and perform work using ions or protons. Materials scientists have built a novel transistor that uses protons, creating a key piece for devices that can communicate directly with living things.  |
| Autonomous car navigates the streets of Berlin Posted: 20 Sep 2011 06:52 AM PDT Researchers from Berlin traveled 80 km in total as passengers during a test drive of their autonomous car "MadeInGermany" over the weekend. The car is driven by computers - the safety driver behind the steering wheel only monitors the car's behavior. The autonomous car is a conventional VW Passat modified for "drive by wire." Electronic commands from the computer are passed directly to the accelerator, the brakes, and the steering wheel of the vehicle.  |
| Researchers make visible the structure of the smallest crystals Posted: 20 Sep 2011 04:55 AM PDT A radical new way of making structures visible at the nano level has now been developed. This new method makes it possible to determine with precision the arrangement of atoms and molecules in a diverse range of materials from cement to pharmaceuticals. The procedure, which is still in its infancy, comes from the field of electron microscopy and can resolve the structure of the tiniest crystals.  |
