Fukushima Debris on Course to Hit U.S.

Debris from the devastating tsunami that hit Japan on March 11 has turned up exactly where scientists predicted it would after months of floating across the Pacific Ocean. Finding and confirming where the debris ended up gives them a better idea of where it's headed next. The magnitude 9.0 quake and ensuing tsunami that struck off the coast of Tohoku in Japanwas so

Bismuth-based semiconducting material could enable control of electron spin

In the developing field of spintronics, physicists are designing devices to transmit data using the inherent axial rotation, or spin, of electrons rather than their charge as is used in electronics. Weak coupling of electron spin to electrical currents, however, makes gaining this level of control difficult

Shiroube Makes Travel Social, Cheap, Unusual

Anyone can be a tour guide--and redefine the term while they're at it--with this Japanese travel startup. Tatsuo Sato got the idea for his startup, Shiroube , during a trip to Eastern Europe. While in Belarus, Sato made a sort of barter arrangement with a local student.

Current flowing along the edges of a promising quantum device is insensitive to its magnetic impurities

Conductors of electrical current, including copper, heat up and limit the ability to increase circuit densities. Unusual materials that exhibit the so-called ‘quantum spin Hall effect’, in which current can flow without dissipating heat, could provide an alternative to conventional metals.
