Scientists may make definitive Higgs boson announcement in

March

GENEVA (Reuters) - Scientists at Europe's CERN research

center said on Wednesday they may be able to definitively

announce at a conference next March that they had discovered

the elusive Higgs boson. But they dismissed suggestions

circulating widely on blogs and even in some science journals

that instead of just one type of the elementary particle they

might have found a pair.

Three-nation crew blasts off for space station

ALMATY (Reuters) - A Soyuz spacecraft carrying a Russian,

an American and a Canadian blasted off on Wednesday to the

International Space Station (ISS), where the men are to spend

half a year in orbit. The Russian-built Soyuz TMA-07M lifted

NASA crashes two probes into a mountain on the moon

CAPE CANAVERAL, Florida (Reuters) - A pair of NASA

moon-mapping probes smashed themselves into a lunar mountain on

Monday, ending a year-long mission that is shedding light on

how the solar system formed. The Gravity Recovery and Interior

Laboratory, or GRAIL, spacecraft had been flying around the

moon, enabling scientists to make detailed gravity maps. The

probes sped up slightly as they encountered stronger gravity

from denser regions and slowed down as they flew over

less-dense areas.
