Strictest targets pledged to tackle England sewage discharges

Strictest targets pledged to tackle England sewage discharges

Science
The government has published a plan to reduce sewage discharges into England's rivers and the sea, promising the "strictest targets ever".Water firms will have to deliver the "largest infrastructure programme in water company history", it says.Last week pollution warnings were in place on nearly 50 beaches after heavy rainfall led to water companies discharging untreated sewage.The Liberal Democrats branded the new plan a "cruel joke".They said consumers would pay for "the mess made by water companies".Water companies discharged untreated sewage into rivers in England more than 400,000 times in 2020, according to official figures.The Liberal Democrats called the government's targets "flimsy", predicting they would still allow 325,000 sewage dumps a year in 2030.

Rejuvenation of woman’s skin could tackle diseases of ageing

Fátima SantosResearchers have rejuvenated a 53-year-old woman's skin cells so they are the equivalent of a 23-year-old's.The scientists in Cambridge believe that they can do the same thing with other tissues in the body.The eventual aim is to develop treatments for age-related diseases such as diabetes, heart disease and neurological disorders.The technology is built on the techniques used to create Dolly the cloned sheep more than 25 years ago.The head of the team, Prof Wolf Reik, of the Babraham Institute in Cambridge, told BBC News that he hoped that the technique could eventually be used to keep people healthier for longer as they grow older."We have been dreaming about this kind of thing. Many common diseases get worse with age and to think about helping people in this way is super ex...

Getty ImagesHave you ever been asked by the doctor how much something hurts out of 10? Pain tolerance is highly subjective which can make it difficult for doctors to pinpoint why someone's pain may be as high as they say it is. My five might be your seven, or my 10 could be your three. A new study published in Nature Medicine is looking to address this. Researchers used artificial intelligence techniques to analyse knee X-rays to "predict patients' experienced pain" for those suffering from osteoarthritis of the knee.This involved 36,369 observations gathered from 4,172 patients. The computer analysis could pick up things that a radiologist might miss."We didn't train the algorithm to predict what the doctor was going to say about the X-ray," says Ziad Obermeyer, an assistant professor at...
