Public research university in Johannesburg, South Africa, founded in 1922 and known for work in palaeontology, human origins, physics and health sciences.
Researchers have named Musango matusadonaensis, a 210-million-year-old Zimbabwean dinosaur, and say Zimbabwe's dinosaurs include species unique to the region. The authors suspect ancient climate explains the split and say they are still working out why.

A UEA-led team with South African colleagues reports that a prepared light beam grows left- and right-handed spinning regions in free space. The university says beam structure sets where they appear, with no special lenses, mirrors or materials.

An international team has named Musango matusadonaensis, the second Triassic dinosaur from Lake Kariba's rocks known only from Zimbabwe. The researchers suspect the ancient environment set these animals apart from South Africa's dinosaurs, though two species from one area cannot yet test that idea.

La Trobe researchers describe DNH 127, the first adult Homo erectus fossil from South Africa's Drimolen cave, dated to 2 million years ago. It is 200,000 years older than adult specimens found elsewhere and supports a first-appearance date that had rested on a child's skull from the same cave.

At Wits, a beam whose polarization structure turbulence had rendered unrecognizable still delivered its skyrmion number unchanged. That is the basis for arguing free-space links should be made robust by encoding rather than by correction.

A 12-week release near Mamfene pushed Anopheles arabiensis numbers down and they climbed back once it stopped, an unpublished result that counts mosquitoes rather than malaria cases, which is the harder endpoint still to come.

A draft bill would make registration with SACNASP compulsory for practising natural scientists. Senior researchers told Nature they had not heard of it, or of the possible prison term.
