Reports: Japan to Continue Research Whaling in Pacific

Japan has decided to continue its whaling program in the Pacific Ocean, reports said Friday, despite losing a United Nations court case on its other "research" hunt in the Antarctic.

If confirmed, the move will likely spark anger among environmentalists who hailed last month's ruling by the U.N.'s International Court of Justice (ICJ) that Tokyo's hunt in the Southern Ocean was a commercial activity disguised as science.

Preglacial Landscape Found Deep under Greenland Ice

U.S. geologists said Thursday they have uncovered a preglacial tundra landscape preserved for 2.7 million years far below the Greenland ice sheet.

Glaciers are known to scrape everything off any given plot of land -- vegetation, soil and even the top layer of bedrock -- so scientists expressed great surprise that they had found the landscape in pristine condition below two miles (three kilometers) of ice.

Study: Down's Chromosome Cause Genome-Wide Disruption

The extra copy of Chromosome 21 that causes Down's syndrome throws a spanner into the workings of all the other chromosomes as well, said a study published Wednesday that surprised its authors. 

Using data from a set of twins, one with Down's and one without, researchers found a major difference in how genes functioned between the two.

Study: Sharks are Not 'Living Fossils'

Modern sharks are not "living fossil" replicas of their prehistoric ancestors but have evolved significantly over millions of years to develop their hallmark design, a consensus-busting study said Wednesday.

The newly discovered fossil skull of a shark-like ancestor of all jawed vertebrates adds to evidence that a bony skeleton, not a cartilaginous one, was the prototype.

Paleontologists Discover Land Herbivores' Earliest Ancestor

Paleontologists unearthed the oldest ancestor of land-dwelling herbivores with the discovery of a 300-million-year-old skeleton, shedding light onto plant eaters' emergence on land, a study said Wednesday.

A partial fossil of the animal, called Eocasea martini, is "the first link between carnivores and herbivores, the transition," Robert Reisz, the article's principal author and professor at Canada's University of Toronto Mississauga, told Agence France Presse.

Oil Drilling Possible 'Trigger' for Deadly Italy Quakes

Italy's Emilia-Romagna region on Tuesday suspended new drilling as it published a report that warned that hydrocarbon exploitation may have acted as a "trigger" in twin earthquakes that killed 26 people in 2012.

The scientific report was commissioned after the quakes amid popular anger over alleged links to drilling activities, particularly an oil field, a gas storage facility and a geothermal energy plant in the area.
