NASA's Shane Kimbrough and Andrei Borisenko and Sergei Ryzhikov of Roscosmos blasted off at 0805 GMT from the Baikonur cosmodrome in Kazakhstan after their launch had been delayed by nearly one month because of technical issues.   

A European lander started a three-day, million-kilometer (621,000-mile) descent to Mars on Sunday, quitting its mothership to test technology for a daring mission to scout the Red Planet for signs of life.

A trio of French, British and Dutch scientists won the Nobel Chemistry Prize on Wednesday for developing molecular machines, the world's smallest machines that may one day act as artificial muscles to power tiny robots or even prosthetic limbs.

The study of "strange states" of matter, which may one day yield superfast and small computers, earned British scientists David Thouless, Duncan Haldane and Michael Kosterlitz the Nobel Physics Prize on Tuesday.

Yoshinori Ohsumi of Japan on Monday won the Nobel Medicine Prize for his work on autophagy -- a process whereby cells "eat themselves" -- which when disrupted can cause Parkinson's and diabetes.
