Climate scientists said Wednesday they found evidence to back predictions for a future with lower average rainfall, even though Earth's past warming episodes had led to more precipitation, not less.

Writing in the journal Nature, researchers said they had found proof that global warming caused by Man's greenhouse-gas emissions has a different effect on rainfall than warming caused by increased solar radiation.

Google on Wednesday launched a global science fair by inviting students around the world to present ideas that could change the world and perhaps become the next Ada Lovelace.

Lovelace was a teenager in the early 1800s when she became fascinated with math and went on to write what is considered to be the first computer program.

A genetic variant commonly found in Chinese people may help explain why some got seriously ill with swine flu, a discovery scientists say could help pinpoint why flu viruses hit some populations particularly hard and change how they are treated.

Less than one percent of Caucasians are thought to have the gene alteration, which has previously been linked to severe influenza. Yet about 25 percent of Chinese people have the gene variant, which is also common in Japanese and Korean people.

A smoker's craving to light up can be tamed by carefully targeted magnetic fields applied to the brain, a senior researcher from a Japanese-Canadian team said Wednesday.

Scientists managed to zoom in on the exact spots that drive the need for nicotine, noting that a mental connection made when a smoker is able to have a cigarette markedly increases the desire to spark up.

The road to hell is paved with good intentions, as they say: the more housework married men do, the less sex they have, according to a new study published Wednesday.

Husbands who spend more time doing traditionally female chores -- such as cooking, cleaning, and shopping -- reported having less sex than those who do more masculine tasks, said the study in the American Sociological Review.

The European Commission said Monday it would draw up "stringent" measures to protect bees from dangers attributed to certain pesticides, but pulled back from an anticipated ban

Residents across northern China battled through choking pollution on Tuesday, as air quality levels rose above index limits in Beijing amid warnings that the smog may not clear until Thursday.

Visibility was reduced to around 200 meters in the center of the capital, where mask-wearing pedestrians made their way through a murky haze, despite warnings from authorities to stay indoors unless absolutely necessary.

Ten endangered pygmy elephants have been found dead this month in Malaysian Borneo and are thought to have been poisoned, conservation officials said Tuesday.

Wildlife authorities in Sabah, a state on the eastern tip of the island, have formed a taskforce together with the police and WWF to investigate the deaths.

Two science projects — one to map the human brain, the other to explore the extraordinary properties of the carbon-based material graphene — were declared the winners Monday of an EU technologies contest and will receive up to €1 billion ($1.35 billion) each over the next 10 years.

The projects were selected from four finalists that been chosen from 26 proposals.

Japan launched two intelligence satellites into orbit on Sunday amid growing concerns that North Korea is planning to test more rockets of its own and possibly conduct a nuclear test.

Officials say the launch Sunday of the domestically produced HII-A rocket went smoothly and the satellites — an operational radar satellite and an experimental optical probe — appear to have reached orbit.
