Novel silicon electrodes improve lithium-ion batteries

Stanford University scientists have dramatically improved the performance of lithium-ion batteries by creating novel electrodes made of silicon and conducting polymer hydrogel, a spongy material similar to that used in contact lenses and other household products.

Scientists eye ionic thrusters

When a current passes between two electrodes - one thinner than the other - it creates a wind in the air between. If enough voltage is applied, the resulting wind can produce a thrust without the help of motors or fuel.

'Telepathy machine' close to reality, say scientists

Neuroscientists at the University of California, Berkeley, have been able to listen in on people's thoughts, using brain waves to reconstruct the actual words that subjects have been hearing.

Japanese scientists have developed a device aimed at allowing even the most cack-handed musician to play an instrument.

New technique could allow the paralyzed to 'speak'

University of Utah scientists have demonstrated that planting microelectrodes on the surface of the brain can allow people to 'speak' with their thoughts.
