Blobs of human brain planted in rats offer new treatment hope
Scientists suggest patient ’s own cells could be grown in the lab and used to repair stroke or trauma injuriesBlobs of human brain tissue have been transplanted into the brains of rats in work that could pave the way for new treatments for devastating brain injuries.The groundbreaking study showed that the “human brain organoids” – sesame seed-sized balls of neurons – were able to integrate into the rat brain, linking up with their blood supplies and communicating with the rat neurons.Continue reading...

Joe Farman obituary
Scientist whose discovery of the depletion of the ozone layer sparked global action to phase out dangerous chemicalsJoe Farman, who has died aged 82, was the leader of a small group of scientists who made one of the most important discoveries in recent history. In 1985, they published a landmark paper on the ozone layer, the protective skin that filters the sun's ultraviolet rays and without which the rays can cause cancers and eye damage. Their research showed that the ozone layer was being rapidly depleted over the Antarctic.Just two years later, world governments signed the Montreal protocol, a treaty phasing out the us...
