The collision of India with Asia causes large earthquakes and active faults along the southern margin of the Himalaya. But has localized erosion by monsoon rains created new faults in the interior of the range?

If a nanoscale gallium arsenide structure is excited with an oscillating magnetic field, superpositions of nuclear spin states can be created and detected electrically. Quantum computing could be the beneficiary

Neuronal competition helps connections to form in the brain: the branches of less active neurons are more likely to retract — and, it now seems, less likely to grow — than those of their more active neighbours
