Tromsoe (Norway): An area of an Antarctic ice shelf almost the size of New York City has broken into icebergs this month after the collapse of an ice bridge widely blamed on global warming, a scientist said.

health sciences Mussels in surgery Natural adhesive proteins secreted by marine mussels may replace sutures in surgery. Sutures, made from sheep intestines, are used to repair tissues in a surgery. Sutures can cause infection and inflammation. Synthetic adhesives are also used to repair tissues but they are not biodegradable and damage the tissues. The researchers found the mussel

An area of an Antarctic ice shelf almost the size of New York City has broken into icebergs in April after the collapse of an ice bridge widely blamed on global warming, a scientist said on Tuesday.

The southern ozone hole has changed weather patterns around Antarctica and cooled the air above the east part of the continent, according to new research.

A study of Greenland's icesheet has revealed that a vast store of planet-warming methane appears to be more stable than thought, easing fears of a rapid rise in temperatures, a scientist said on Friday.

An expansion of sea ice around Antarctica is linked to a hole in the ozone layer high in the atmosphere, according to a study on Tuesday that helps clear up a mystery about global warming.

The UN Climate Panel says seas could rise by 18-59 cms (7-24 inches) by 2100, without taking account the possible acceleration of a melt of ice sheets in Antarctica or Greenland.

Even a small thaw of Antarctica and Greenland would affect sea levels since together they lock up enough ice to raise sea levels by about 65 metres (215 feet) if they all melted.

Washington: Hidden in the bonechilling dark beneath an Antarctic glacier, a colony of strange bacteria is thriving. Scientists investigating the flow of blood-red water from beneath the glacier discovered the bacteria, which have survived for millions of years, living on sulfur and iron compounds, they report in the journal Science.

An uncharted reservoir of briny liquid, buried under an inland Antarctic glacier, supports unusual microbial life in a place where life is unthinkable. After sampling the outflow from below Taylor Glacier of the East Antarctic Ice Sheet, researchers believe that microbes have adapted over the past 1.5 million years to manipulate sulphur and iron compounds to survive, without photosynthesis.
