People who are fully vaccinated against Covid-19 are highly protected against severe infection, hospitalization and death caused by the virus. But coronavirus cases among the fully vaccinated — so-called "breakthrough" Covid cases — are still being seen among those who have had two doses. While…

People who have recovered from Covid-19 tend to score significantly lower on an intelligence test compared to those who have not contracted the virus, according to new research published in The Lancet journal EClinicalMedicine. The findings suggest that the SARS-CoV-2 virus that causes Covid-19 can produce substantial reductions in cognitive ability, especially among those with more severe illness. “By coincidence, the pandemic escalated in the United Kingdom in the middle of when I was collecting cognitive and mental health data at very large scale as part of the BBC2 Horizon collaboration the Great British Intelligence Test,” said lead researcher Adam…

Backed by governments, business, academics and investors in an industry worth $110bn (£82.5bn) – and estimated to be worth $610bn by 2025 – scientists have spent decades attempting to harness the power of genomics and artificial intelligence to find a way to prevent or even reverse ageing.
