"Below, an animation shows a photo - and a progressively digitally enhanced version - of what could be the oldest known example of rock art in the world. The outline of a hand, dated to at least 67,800 years ago, was discovered in an Indonesian cave. It could be evidence for a controversial theory that early humans arrived in Sahul - the landmass that once encompassed modern-day Australia and New Guinea - by 65,000 years ago, around 15,000 years earlier than otherwise thought."
"A 33-year-old man was kept alive for 48 hours by an external artificial-lung system, after complications from a severe infection meant his lungs had to be removed. The system maintained the man's oxygen levels and continuous blood flow across the heart - a first for an external lung device - until he could receive a double lung transplant. Operating the system currently requires multiple specialist teams, but the team who developed it hope it can be refined for use in any hospital."
Researchers are working to reproduce the smells of heritage objects and historical sites, including mummies and soils from the Battle of Waterloo, to recover olfactory context. Science images of the month feature striking scenes such as a firefly near a particle accelerator and a progressively digitally enhanced hand stencil dated at least 67,800 years from an Indonesian cave, which could point to human presence in Sahul by 65,000 years ago. Clinicians sustained a 33-year-old man for 48 hours with an external artificial-lung system that preserved oxygenation and continuous blood flow until a double lung transplant. Charity-funded hackathons are applying AI tools to find genetic causes of undiagnosed rare diseases.
