A joint team of UK and Australian researchers has found that two separate groups of Antarctic octopuses, from the Ross and Weddell seas on different sides of the continent, are almost genetically identical.

Scientists report in the journal Nature that an Antarctic ice sheet may start to melt rapidly in this century.

As temperatures warm along Antarctica’s outer fringes, it allows for invasive plants and organisms to be carried in inadvertently by visiting scientists and tourists, putting the pristine ecosystem at risk, researchers have found.

Scientists have created a detailed map called BEDMAP of Antarctica's rock bed that lies underneath its icy surface.

Icebergs apparently head off to South Georgia when they are going to die.
