Sydney, Sept.28 : Official estimates suggest there are now 23 million feral pigs in Australia, outnumbering the continent's human population of 21 million.

According to news.com.au, they are the descendants of domestic pigs which explorers such as Captain Cook released as a living larder for future expeditions.

The animals found Australia to be hog heaven, with plentiful food, a balmy climate and no natural predators aside from the occasional crocodile and piglet-pinching dingoes.

London, Sept 28 : A radio burst that originated from beyond the Milky Way galaxy has befuddled astronomers.

Initial suspects include the merger of two dense stellar corpses called neutron stars and the complete evaporation of a black hole.

David Narkevic, an undergraduate student at West Virginia University in Morgantown, US, discovered the burst while searching through archived data taken in 2001 by the Parkes radio dish in Australia. He was looking for periodic signals from pulsars – rotating neutron stars – within our galaxy.
