A British research team in Antarctica has launched a long-awaited project to hunt for life in a lake hidden beneath the ice-sheet.

A team of 12 scientists and engineers has begun work at remote Lake Ellsworth.

They are using a high-pressure hose and sterilised water at near boiling point to blast a passage through more than two miles of ice.
