COVER
Reconstruction of a ~2-million-year-old Australopithecus sediba skeleton
(height: ~1.3 meters) based on fossils from the Malapa Hominin 1
(MH1), MH2, and MH4 specimens from Malapa, Gauteng, South Africa.
Brown indicates discovered fossils. Au. sediba exhibits a mosaic
morphology distinct from that of other australopiths and early Homo .
See pages 132 and 163, as well as www.sciencemag.org/extra/sediba.

Van Allen Variation
The two rings of relativistic particles called Van Allen Belts that en-
circle Earth were discovered during the space age, and are known to
pose risks to satellites in geostationary orbit. NASA launched twin
spacecraft, the Van Allen Probes, on 30 August 2012 to measure and
characterize Earth’s radiation belt regions. Baker et al. (p. 186, pub-
lished online 28 February) have shown that a third, unexpected and
temporary, radiation belt formed on 2 September 2012 to disappear
4 weeks later in response to changes in the solar wind.
