Physicists said on Tuesday that they had narrowed the search for the elusive sub-atomic Higgs boson particle that would confirm the way science describes the Universe.

Experiments at Europe's giant atom smasher have "reduced the window where scientists think they will find the Higgs boson," also known as the God Particle, said Bruno Mansoulie, a researcher at the European Organization for Nuclear Research (CERN).

It appears a female has come between one of Canada's celebrity couples.

Toronto's zoo split up a pair of male penguins whose affection for each other drew headlines last month and jokes about "Brokeback Iceberg."

Australian scientists who modeled conditions on Mars to examine how much of the red planet was habitable said Monday that "large regions" could sustain life.

Charley Lineweaver's team, from the Australian National University, compared models of temperature and pressure conditions on Earth with those on Mars to estimate how much of the distant planet was livable for Earth-like organisms.

Japan launched a new spy satellite into orbit Monday amid concerns over North Korea's missile program and to monitor natural disasters in the region, officials said.

The Japanese H-2A rocket carrying an information-gathering radar satellite lifted off at 10:21 am (0121 GMT) from the Tanegashima Space Center in southwestern Japan.

Scientists identify a new species every two days in the Greater Mekong region, the WWF said Monday, in a report detailing 2010's more unusual finds such as a leaf warbler and a self-cloning lizard.

But the conservation group warned some species could disappear before they are ever recorded because of man-made pressures in the Southeast Asian area, described in the report as "one of the last frontiers" for new discoveries.

Researchers have sticky fingers when it comes to NASA's moon rocks and meteorites, and hundreds of samples have gone missing after being loaned out by the U.S. space agency, an audit said Thursday.

NASA Inspector General Paul Martin issued a report detailing foibles such as the U.S. space agency making loans to researchers who never used the samples, or simply losing track of rare pieces dating back to the first U.S. trip to the Moon in 1969.

Honey bees do a little dance to communicate with each other that mimics signals in the brain, a finding that may shed light on how Earth's creatures make choices, scientists said Thursday.

"The decision-making mechanisms in nervous systems and insect societies are strikingly similar," said the study in the December 8 issue of Science Express.

Europe's new Vega rocket, which can place a 1.5-ton satellite into low-Earth orbit, is expected to see its first launch early next year, Arianespace chief Jean-Yves Le Gall said Thursday.

"We will have the first launch in January or February, Le Gall told Agence France Presse in Washington, while noting that he expected to sign contracts soon for the Italian-built rocket.

The Jorge Montt glacier in southern Chile is melting at a rate of a kilometer (0.6 miles) per year, making it one of the world's most visible milestones of global warming, according to researchers.

Chile's Center for Scientific Studies (CECs) said Wednesday that several glaciers in the country's south have shrunk because of global warming but that the 454-square-kilometer Jorge Montt is one of those shrinking the fastest.

NASA's lone surviving Mars rover has been busy exploring its surroundings since it rolled up to its latest crater destination four months ago. Now the solar-powered Opportunity is in search of a place to spend its fifth winter.

The robot geologist has been scouting out sites along the crater rim that not only have interesting rocks to examine but also ample sunshine. The hardy rover survived four previous Martian winters. Scientists expect no different and even drew up a to-do list.
