Understanding our early human ancestors: Australopithecus sediba

Dartmouth College

The fossil site of Malapa in the Cradle of Humankind, South Africa, discovered by Lee Berger of the University of the Witwatersrand, Johannesburg, in August 2008, has been one of the most productive sites of the 21st century for fossils of early human ancestors or hominins. A new hominin species, Australopithecus sediba (Au. sediba), was named by Berger and his colleagues, following the discovery of two partial skeletons just under two million years old, a juvenile male individual-- Malapa Hominin 1 (MH1)-- and an adult female, Malapa Hominin 2 (MH2). The skeletons are under the custodianship of the University of the Witwatersrand, where they are being kept.

Body-Painting Protects Against Bloodsucking Insects

Lund University

A study by researchers from Sweden and Hungary shows that white, painted stripes on the body protect skin from insect bites. It is the first time researchers have successfully shown that body-painting has this effect. Among indigenous peoples who wear body-paint, the markings thus provide a certain protection against insect-borne diseases.

Hand-knitted Molecules

Empa, Swiss Federal Laboratories for Materials Science and Technology

Molecules are usually formed in reaction vessels or laboratory flasks. An Empa research team has now succeeded in producing molecules between two microscopically small, movable gold tips – in a sense as a "hand-knitted" unique specimen. The properties of the molecules can be monitored in real time while they are being produced. The research results have just been published in Nature Communications.
