Nanotechnology used in autonomous robots that could work in swarms to clean up oil spills
MIT researchers have used nanotechnology to develop a robot that can autonomously navigate across the surface of the ocean to clean up an oil spill.
Scientists envision using a fleet of the devices, dubbed a Seaswarm, to clean up oil spills more efficiently and at less cost than current methods, according to the university. Researchers report that a fleet of 5,000 Seaswarm robots would be able to clean a spill the size of the recent one in the Gulf of Mexico in a single month.

The claim is that Mars will appear so large in the sky on Friday that it will look as if Earth has two moons. But the planet will appear as a mere pinprick of light, not a moonlike orb.

Scientists have catalogued 450 exoplanets in the past 15 years, but most finds include up to three planets per star, usually gargantuan balls of gas similar to Jupiter or Saturn. (Illustration by France's space agency, the Centre National d'Etudes Spatiales)
