Researchers at Wits University in South Africa, including Peter Schmid from the University of Zurich, have described the anatomy of a single early hominin in six new studies. Australo-pithecus sediba was discovered near Johannesburg in The...
The existence of this archaic human group came to light in 2010 when DNA from a piece of a finger bone and two molars that were excavated at Denisova Cave in the Altai Mountains of southern Siberia was studied. Shown here, the entrance to the cave.
A pioneering team from IBM in Zurich has published single-molecule images so detailed that the type of atomic bonds between their atoms can be discerned. The same team took the first-ever single-molecule image in 2009 and more recently published images of a molecule shaped like the Olympic rings.
The discovery of microbes thriving in the salty, sub-zero conditions of an Antarctic lake could raise the prospects for life on the Solar System's icy moons. Researchers found a diverse community of bugs living in the lake's dark environment, at temperatures of -13C. Furthermore, they say the lake's life forms have been sealed off from the outside world for some 2,800 years. Details of the work have been outlined in the journal PNAS.
