Twin Study Shows That Genetic Changes Caused by Space Travel Are Temporary

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 Develop “Fake Alcohol” That Gets You Buzzed But Never Drunk

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.

Scientists Use GM Brewer’s Yeast to Produce THC and Other Cannabinoids

Researchers from the University of California have modified brewer’s yeast (Saccharomyces cerevisiae) to manufacture cannabis compounds including the psychoactive chemical THC in a world’s first. This technology could soon provide researchers with cheaper, more efficient and reliable access to medicinal cannabis compounds that are found in trace amounts in nature.

India’s New Pay-per-Paper Proposal Sparks Controversy

Indian researchers are criticizing a government proposal by which graduate students who publish in select journals will be paid extra money. Such a practice could degrade the quality of research and increase scientific misconduct, critics say. Months-long protests of academics against the proposal have just concluded in India and new ones are already on the horizon.

Chinese Scientists Clone GM Macaques to Study Mental Disorders in a World’s First

Researchers from the Chinese Academy of Sciences’ Institute of Neuroscience in Shanghai have been the first to clone genetically-altered primates. Five infant macaques share the exact same genes, derived from a fibroblast taken from the skin of a donor monkey. This technique could theoretically produce an unlimited number of replicas and provide clear benefits for medical testing.
