A week after publishing the starkest warning yet on the risks of climate change, U.N. experts meet in Berlin from Monday to assess options for limiting the threat.

A draft of the report, seen by Agence France Presse, suggests there is a 15-year window for feasible and affordable action to safely reach the U.N.-targeted global warming limit.

A volcano in central Ecuador spewed up a column of hot ash and smoke 10 kilometers (six miles) high on Friday, increasing fears of an eruption.

Activity has been building at the Tungurahua volcano 130 kilometers south of the capital Quito since early February, and on Friday experts reported a loud explosion "that lasted for five minutes" and an expulsion of ash.

Saturn's moon Enceladus is home to an ocean of melted water beneath its surface, and could be a source for alien microbes, scientists said Thursday.

The first measurements of the subsurface water at the south pole of the small and icy moon were made by the U.S. space agency's Cassini spacecraft, and are described in the journal Science.

The space consortium Arianespace has successfully launched a rocket that lofted the first Earth-observation satellite for a new European project.

The Sentinel-1A satellite was launched into orbit by a Soyuz rocket on Thursday evening from a spaceport in French Guiana. The rocket's flight lasted 23 minutes.

An international exhibition in New York explores the fascinating world of prehistoric flying reptiles, the pterosaurs who ruled the skies when dinosaurs ruled the earth millions of years ago.

"Pterosaurs: Flight in the Age of Dinosaurs," opens on Saturday and runs until January 2015 at the American Museum of Natural History, co-curated with an expert from Brazil.

The Moon was formed about 95 million years after the birth of our Solar System, in a collision that also settled the structure of Earth as we know it, according to the latest attempt at dating that impact.

A study in the journal Nature said the crash between an early, proto-Earth and a Mars-sized object that dislodged what would become the Moon, happened some 4.470 billion years ago -- give or take 32 million years.

Scientists have created a detailed, three-dimensional wiring diagram of the mouse brain. That should help researchers seek clues about how the human brain works in health and disease.

It's the first brain-wide wiring diagram for a mammal at such a level of detail. While it doesn't reveal every connection between each of the rodent's 75 million brain cells, it shows how parts of the brain are connected.

His eyes hidden by sunglasses, the soft-spoken African gestured at the model camel on his table, its hump hidden by a mysterious contraption topped with a windmill.

"I'm the only Chadian with five patented inventions to his name," Oumar Ayoumbaye said proudly, before pitching his low-tech, camel-borne air conditioning unit which he says could revolutionise desert life.

Japan said Thursday it was cancelling its annual Antarctic whaling hunt for the first time in more than a quarter of a century in line with a U.N. court ruling that the program was a commercial activity disguised as science.

A "deeply disappointed" Tokyo earlier this week said it would honor Monday's judgement by the United Nations' Hague-based International Court of Justice but did not exclude the possibility of future whaling programs.
