International crew of three reaches orbiting space station

CAPE CANAVERAL, Florida (Reuters) - A Russian Soyuz capsule

carrying a multinational crew of three arrived at the

International Space Station on Friday, setting the stage for a

Canadian for the first time to take command of the orbital

research base. The spacecraft carrying Chris Hadfield from the

Canadian Space Agency, NASA's Tom Marshburn and Russian

cosmonaut Roman Romanenko blasted off from Kazakhstan's

Baikonur Cosmodrome on Wednesday and parked at the station's

Rassvet docking module at 9:09 a.m. EST as the ships sailed 255

Scientists in Hong Kong map initial anti-aging formula

HONG KONG (Reuters) - Scientists in Hong Kong appear to

have mapped out a formula that can delay the aging process in

mice, a discovery they hope to replicate in people. Their

finding, published in the December issue of Cell Metabolism,

builds on their work in 2005 which shed light on premature

aging, or progeria, a rare genetic disease that affects one in

four million babies.

Long-lived bats offer clues on diseases, aging

HONG KONG (Reuters) - The bat, a reservoir for viruses like

Ebola, SARS and Nipah, has for decades stumped scientists

trying to figure out how it is immune to many deadly bugs but a

recent study into its genes may finally shed some light,

scientists said on Friday. Studying the DNA of two distant bat

species, the scientists discovered how genes dealing with the

bats' immune system had undergone the most rapid change.

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
