BEIJING (Reuters) - Scientists have found the fossil of a new herbivorous dinosaur species that stood five meters (5.5 yards) high and lived 60 million years ago, the official Xinhua agency reported on Thursday.

The large long-necked sauropod, which was found in Eastern Zhejiang province and has not yet been named, was around 15 meters long, the report quoted a museum curator as saying.

PARIS (Reuters) - French carmaker Renault and the Sita waste management firm of Suez will on Thursday announce a joint venture company to recycle old passenger and commercial vehicles, a spokesman said.

The companies will hold a news conference at 1700 GMT (12 p.m. EST) at Renault's marketing offices in Boulogne-Billancourt.

Despite of this potential conflict, Kai Chan of the University of British Columbia believes there is a way to ensure Canadian First Nations fishers can benefit from the otters' presence.

"Efforts to restore wildlife populations should not be played out in a win-lose framework that pits conservation against the economic interests of the local people," observes Chan, who spoke at the American Association for the Advancement of Science Annual Conference in Boston (February 14 to 18).

The new findings from the study led by Ralph Lorenz, Cassini radar team member from the Johns Hopkins University Applied Physics Laboratory, Laurel, Md., are reported in the Jan. 29 issue of the Geophysical Research Letters.

"Titan is just covered in carbon-bearing material -- it's a giant factory of organic chemicals," said Lorenz. "This vast carbon inventory is an important window into the geology and climate history of Titan."

The Gulf States are investing in radical initiatives to strengthen science but results are not guaranteed, reports Waleed Al-Shobakky.

Farouk El-Baz routinely shifts between two views of the Gulf countries. One day the Egyptian-American geologist will be in his Boston office poring over detailed satellite images of the Arabian Peninsula. The next he will be continuing his study from a much closer range, flying to Qatar, Saudi Arabia or the United Arab Emirates to do his geology fieldwork — and to serve as a science adviser.

Tiny particles of pure silica coated with an active material could be used to remove toxic chemicals, bacteria, viruses, and other hazardous materials from water much more effectively and at lower cost than conventional water purification methods, according to researchers writing in the current issue of the International Journal of Nanotechnology.
