A team of scientists has reconstructed a skeleton of Australopithecus sediba, a hominid that lived about two million years ago, putting together the bones of some partial skeletons found in 2008 in Malapa, about 45 km (about 30 miles) from the capital city of South Africa, Johannesburg.

Yesterday the British biologist Robert Edwards, a pioneer of artificial fertilization, died following a long illness. Born on September 27, 1925, Edwards received the Nobel Prize in Physiology or Medicine for the development of in vitro fertilization in 2010.

In recent days, the announcement arrived that a group of Russian researchers had discovered in Lake Vostok, Antarctica, bacteria of unknown type. Subsequently, however, the head of the genetics laboratory of the Institute of Nuclear Physics in St. Petersburg where the bacteria were analyzed stated that the samples had been contaminated during the research.
