Scientists are set to embark on one of the most comprehensive studies to date into how digital technologies impact the mental health of young people. As digitisation of information continues, and with the pandemic helping to accelerate the change, the always-on world of social media and rapid news cycles has adversely ... Read More »
A blood test that can detect more than 50 different types of cancer could speed up diagnosis, a new study suggests.

Of those 323 patients, 244 ... Read More »
The global loss of wildlife is “significantly more alarming” than previously thought, according to a new study that found almost half the planet’s species are experiencing rapid population declines. Humans have already wiped out huge numbers of species and pushed many more to the brink – with some scientists saying we are entering a “sixth mass ... Read More »
Scientists have used a “surprising” new animal model – the African killifish – to show that muscles reverse to an “early-life” state towards the end of life, an advance which may lead to reversing age-related strength loss in humans. While previous research has shown that muscles start to waste in old age ... Read More »
