Graphene gets spintronics
The basis of microelectronics is the manipulation of charged electrons. The basis of spintronics is the conversion of electricity to magnetism and vice versa in order to manipulate the spin of electrons. Both approaches can produce transistors and other elements used in electronics (computers et al), but spintronics has advantages: Unlike the charge of electrons, [...]

Working toward a ‘triple threat’ graphene transistor
Anyone paying attention to science or technology this year must have noticed that graphene is a big deal. As in two guys, Andre Geim and Konstantin Novoselov, both at the University of Manchester (UK), winning a Nobel Prize in physics for (more or less) launching graphene on its way to fame and fortune. Hardly a [...]

Nobels for trend setting: Graphene and IVF
Nobel Prizes are sometimes perfunctory – lifetime achievement, arcane fields. Not this year. The Nobel committees seem to have their brains operating with a vision; they’re seeing a larger context and signaling their awareness. This year’s Nobel Prize for Medicine and Physiology went to Robert Edwards the founding father of in-vitro fertilization (IVF). This is [...]
