This Friday night, NASA will launch Kepler, a satellite designed to discover Earth-sized planets -- potential homes for alien life forms -- that may orbit nearby stars. But that's only part of what the new orbiting telescope can do, says MIT planetary scientist Sara Seager (inset), one of the members of the Kepler team. For instance, it can learn a lot more about the many "hot Jupiters" -- giant planets that have been discovered orbiting very close to their parent stars -- including how reflective they are, which could be a clue to their composition. New discoveries could be announced within a year, if all goes well with Friday's launch, Seager says, and "there's no reason why Kepler shouldn't find hundreds of new planets." Image / NASA
By sidestepping the need for costly interventions, a new method could potentially reveal gene regulatory programs, paving the way for targeted treatments.
A new design tool uses UV and RGB lights to change the color and textures of everyday objects. The system could enable surfaces to display dynamic patterns, such as health data and fashion designs.
