Chinese scientist edited the genes of twin girls to try to make them more resistant to HIV.
In November last year, He announced that he had edited the CCR5 gene in twin girls born earlier in the year. This was met with global condemnation, with researchers saying his actions were unethical and dangerous. The potential long-term consequences of editing a person's genome is not known—the CCR5 gene is known to relate to the way HIV enters the blood, but research is also starting to suggest it is involved in memory and other neurological mechanisms.
Their findings indicated people with this mutation may have a lower life expectancy, with carriers being 20 percent less likely to reach the age of 76 than those without it. The mutation also appeared to reduce protection of some infectious diseases. Concluding, they said it appears the mutation had a negative effect on health.said the authors were retracting the paper after exchanges with other scientists who had made them aware of a"genotype calling bias in the underlying U.K.
"Further analyses confirmed that the central finding of the study—that homozygous CCR5-∆32 mutation is associated with increased mortality in the UK Biobank—is a result of this technical artifact. Because the main conclusion of the paper is invalid, both authors, Xinzhu Wei and Rasmus Nielsen, wish and agree to retract the Brief Communication in its entirety,"

Study: 83% Of Marathon Spectators Only Attend For Sick Thrill Of Watching Fellow Man SufferCHICAGO—In a new study released Monday by Northwestern University, researchers found that 83 percent of marathon spectators only attend to relish the sick thrill of watching their fellow man suffer. “Analysis revealed that the guilty pleasure of watching a group of exhausted, miserable human beings painfully push their bodies to the limit in a 26-mile race is the primary motivation of every four out of five observers at the event,” said lead researcher Dr. Philip Sharp, noting that a large majority of people who watched marathons were there for the deliciously sinful delight of witnessing the pained expressions of struggling, out-of-breath competitors as they lose all control of their bodies and collapse. “Data found that scores of observers would even bring signs, air horns, and bells to encourage the runners to continue the parade of human misery just for their own perverse entertainment. Even the 17 percent of the audience who are primarily there to support a friend or loved one in the race admit they can’t help but savor the intoxicating, depraved rush of satisfaction they feel when watching a runner puking on the side of the road as their digestive system shuts down due to the intense level of exercise.” Sharp added that marathon officials were already citing the study as they considered plans to extend the length of races and ban water and carbohydrate-based energy gels in order to improve attendance and the overall enjoyment for spectators.
