London, July 12: Scientists are using a device dubbed the ‘Super Sucker’ to suck up seaweed from reefs, resulting in cleaner and thriving reefs.

Beijing - Envoys from six nations were trying to reach agreement on Saturday on a joint statement on North Korea's nuclear programme, South Korea's Yonhap news agency reported. 

London, July 12 : A new research has suggested that hot and massive, rocky worlds called ‘super-Earths’, may provide the right conditions for life, even those orbiting searingly close to their star

Washington, July 12 :

Washington, July 11 : Scientists at the CSIRO Queensland Bioscience Precinct in Australia have identified the genetic basis for the black, and white, coat color in a breed of domestic sheep.

In the wild, mammalian coat color is essential for camouflage and plays a role in social behavior.

Coat color also strongly influences the animals we choose to breed both as livestock and as pets. Understanding the genetic determinants of coat color in livestock species such as sheep, specifically bred for their coat color, is critical for improving efficient selection of the desired trait.

Washington, July 11 : Scientists have determined that the ecosystem of the Antarctic Peninsula is changing fast, driven by warming waters and a loss of sea ice.

According to a report in Discovery News, these findings have been made by three researchers who have spent decades studying Antarctica''s denizens.

These researchers have observed interconnected changes at the bottom of the Earth that are changing the ecology of Antarctica over just decades after some 30 million years of relative isolation.

"The changes are profound," said Hugh Ducklow of the Marine Biological Research Laboratory in Woods Hole, Massachusetts.
