If you're like anyone else, you have no idea how much you pay for electricity. A new app will let you use your phone to see when it's the cheapest, and pick that moment to charge your car.

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

Molecules that suddenly transform into new structures when stimulated by photons or electrons play key roles in many chemical and biological processes. Recently, chemists have discovered that adding transition metals such as copper to photo-responsive organic ligands produces materials with high solar conversion efficiencies, owing to the metal’s ready supply of light-activated electrons.

If there were a Hall of Fame for materials, manganites would be among its members.
