American twin astronauts provided NASA scientists with rare data on how long-term spaceflight affects the human body. While one brother spent a record-setting 340 days in outer space, the other was stranded on Earth. They spent years under a medical microscope. A comparative study on their genetic profiles showed differences in length of telomeres and gene expression, which seemed to diminish slowly over time.
Scientists from Washington University in St. Louis have found a new method to genetically alter bacteria and acquire super-strong spider silk. Farming spiders is incredibly inefficient and finding a way to mass-produce the material would bring us a step away from a ready supply of incredibly resilient fabrics. The method could clear the way for the production of other scarce proteins that could even be used for future space missions.
Inventing a product that allows drinkers to enjoy all the benefits of alcohol and none of its drawbacks was a goal of scientist David Nutt for over a decade. He developed a synthetic alcohol substitute he calls Alcarelle, which could eliminate the downsides of alcohol consumption, from hangovers to alcohol-related cancers and even physical addiction.
An advisory panel to the World Health Organization (WHO) has called for the creation of a global registry to monitor gene-editing research in humans. The recommendations of the 18-person committee are aimed at improving transparency and responsibility in the field. An advisory committee did not recommend banning human gene-editing research, but researchers will have to register with the government before beginning an experiment.
