The novel mutation was more commonly seen in people of recent African ancestry, showing how genetic risk factors can differ between groups, the authors say.
is a neurodegenerative condition that progressively worsens people’s motor function and often eventually leads to dementia. It currently affects up to a million Americans
. But there are also known mutations that substantially raise a person’s individual risk, and about 15% of all cases are thought to have a family history of Parkinson’s.Much of the research looking into the genetic underpinnings of Parkinson’s and other diseases has been done with largely European populations. And while we’ve learned a lot from this research, the relative lack of data on other groups means we could be missing important information. A large team of scientists from the U.S.

South African hominin fossils were sent into space and scientists are enragedWhen a Virgin Galactic commercial flight soared into space on 8 September 2023, there were two Virgin Galactic pilots, an instructor and three passengers on board—as well as two fossils of ancient prehuman relatives from South Africa. Timothy Nash, a businessman, carried a clavicle belonging to Australopithecus sediba and the thumb bone of a Homo naledi specimen. The fossils' brief journey—the VSS Unity's flight lasted just an hour—was organized by paleontologist Lee Berger, who led the team that discovered and described Homo naledi in 2015. Berger was granted an export permit in July by the South African Heritage Resources Agency (SAHRA) to take the fossils from the country to the US launch site for VSS Unity. SAHRA is a 'national administrative body responsible for the protection of South Africa's cultural heritage.'
