Polar scares: assault in the Antarctic

Scientists working on a remote Antarctica research station have pleaded to be rescued after accusing one of their team of assault.

The nine-person team had only just arrived for a 13-month overwinter mission at South Africa's Sanae IV Antarctic base when officials in Pretoria received an email saying a team member had become violent. The man was "accused of physical assault, sexual harassment and 'deeply disturbing behaviour'", said Newsweek.

Things have settled a little since then.
