Repeated exposure to extreme heat events accelerates the body's biological ageing, with a Taiwan study of nearly 25,000 people showing that each extra 1.3 °C exposure added about 0.023–0.031 years to the biological clock on average. A genetically modified pig lung was transplanted into a brain-dead 39-year-old recipient and survived nine days with no clear rejection, though the organ swelled after 24 hours and some tissue suffered oxygen-related damage. The US Supreme Court blocked efforts to reinstate almost $2 billion in NIH research grants by invalidating certain district-court decisions, while some other rulings partly favored researchers. Six common quantum myths were also debunked.
A long-term study of almost 25,000 people in Taiwan found that, for every extra 1.3 ℃ a person was exposed to, around 0.023-0.031 years was added to their biological clock on average - an extent comparable to that caused by regular smoking or alcohol consumption. The effect looks small, but cumulatively "can have meaningful public-health implications", says environmental epidemiologist and study co-author Cui Guo.
A lung from a genetically modified pig has been transplanted into a person for the first time. The recipient, a 39-year-old man, was brain-dead, but the organ survived for 9 days. The team behind the transplant notes that there were no signs of rejection, but the organ appeared to be swelling after 24 hours and some of the lung tissue was damaged from a lack of oxygen during the procedure.
