US scientist Karl Deisseroth shares Nobel medicine prize for brain research

Deisseroth and German colleagues Peter Hegemann and Georg Nagel are recognised for research including optogenetics.

BBC, the Guardian, NPR and France 24 report the award of the Nobel medicine prize to three scientists for work on brain activity. BBC and France 24 identify the recipients as Karl Deisseroth, Peter Hegemann and Georg Nagel. The Guardian identifies Deisseroth’s Stanford University and Howard Hughes Medical Institute affiliations, while France 24 explains that optogenetics uses light to control neurones.

What holds up

  • ✓Four outlets corroborate the award and its focus on brain research.
  • ✓BBC and France 24 agree on the three recipients; Guardian and France 24 explicitly identify optogenetics.

What doesn't yet

  • ?Potential applications for dementia, depression and blindness are possibilities, not established treatments in these extracts.
  • ?The supplied summaries do not describe the underlying experiments or clinical evidence.

Ask before you share

  • →What specific discoveries does the prize citation recognise?
  • →Which proposed medical applications have supporting clinical evidence?

Ancient Egyptian skull fractures raise possibility of sacrifice

Research on royal cemetery remains suggests that some people serving early kings may have been killed when their rulers died.

The Guardian reports research finding fractures in several ancient skulls from the royal cemetery at Umm el-Qa’ab near Abydos. Researchers interpret the remains as possible evidence that court officials and craftspeople serving early Egyptian kings were sacrificed when their ruler died.

What holds up

  • ✓The supplied report identifies the cemetery from which the studied remains came.
  • ✓It describes fractures in several skulls as the physical evidence underlying the interpretation.

What doesn't yet

  • ?Sacrifice is presented as a possibility, not an established explanation for every fracture.
  • ?The extract supplies no sample size, dating methods or assessment of alternative causes of injury.

Ask before you share

  • →How were the injuries dated relative to death?
  • →What evidence distinguishes sacrifice from other causes of skull fractures?
