Russian scientists revive an ice age flower

Last updated Saturday, February 25, 2012 - 8:22am

A plant that was frozen in Siberian permafrost for about 30,000 years has been revived by a team of Russian scientists -- and borne fruit, to boot.

Using tissue from immature fruits buried in fossil squirrel burrows some 90 feet below the surface, researchers from the Russian Academy of Sciences in Pushchino managed to coax the frozen remains of a Silene stenophylla specimen into full flower, producing delicate white blooms and then fruit.

MOSCOW -- After more than two decades of drilling in Antarctica, Russian scientists have reached the surface of a gigantic freshwater lake hidden under miles of ice for some 20 million years -- a lake that may hold life from the distant past and clues to the search for life on other planets.

SAN JOSE, Calif. -- Scientists at SLAC National Accelerator Laboratory have created the world's first atomic X-ray laser.

The researchers aimed SLAC's Linac Coherent Light Source at a capsule of neon gas, setting off an avalanche of X-ray emissions to create the shortest, purest X-ray laser pulses ever achieved.
