  • It is unclear to what extent early hominins were adapted to arboreal climbing. Here, the authors show that the nearly complete hand of H. naledifrom South Africa has markedly curved digits and otherwise human-like wrist and palm, which indicates the retention of a significant degree of climbing.

  • Approximately 11.6-million-year-old fossils reveal an ape with arms suited to hanging in trees but human-like legs, suggesting a form of locomotion that might push back the timeline for when walking on two feet evolved.

  • A directly dated Homo sapiens phalanx from the Nefud desert reveals human presence in the Arabian Peninsula before 85,000 years ago. This represents the earliest date for H. sapiens outside Africa and the Levant.

  • These authors demonstrate resonant quantum transitions in a pure antimatter atom—antihydrogen—by using microwave radiation to flip the spin of the positron of an anti-atom in a magnetic trap, thus ejecting the anti-atom.

  • Antihydrogen, the bound state of an antiproton and a positron, has been produced at low energies at CERN since 2002. It is of fundamental interest for testing the standard model of elementary particles and interactions. However, experiments so far have produced antihydrogen that is not confined, precluding detailed study of its structure. Here, trapping of antihydrogen atoms is demonstrated, opening the door to precision measurements on anti atoms.
