Femtoseconds lasers will help formation flying in space
14:26 October 6, 2009 PDT
Theoretical work commissioned to the National Physical Laboratory (NPL) by the European Space Agency has recently concluded that lasers capable of generating extremely short pulses — known as "femtosecond comb lasers" — could be of great help in measuring the distance between two or more spacecraft to an accuracy of just a few microns, an essential component to formation flying space missions scheduled for the next decades.

Scientists defy gravity with metal that pumps liquid uphill

Gravity can make it difficult to move liquid uphill but scientists at the University of Rochester have created a simple slab of metal that does exactly that using the same wicking process that trees employ to pull vast amounts of water from their roots up to their leaves. The metal could be used to pump microscopic amounts of liquid around a medical diagnostic chip, cool a computer's processor or turn almost any simple metal into an anti-bacterial surface. Read More
