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.
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.
New measles outbreaks constantly appear around the globe and vaccination hesitancy and skepticism is at least in part to blame. Latest clinical evidence unequivocally denies any link between autism and the vaccine for measles, mumps, and rubella, in hopes of mitigating the re-emergence of potentially fatal diseases.
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.
Scientists from Europe and the U.S. have managed to restore hearing in an adult mouse model. The mice suffered from so-called DFNB9 deafness, a genetic hearing disorder that represents one of the most frequent causes of congenital deafness. These findings could open doors to new gene therapies for other forms of deafness.
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.
The Internet has an abundance of articles and posts about cancer. People want to educate themselves more about the harms and threats that simple everyday things may bring, that can potentially cause cancer.
Humans are social beings and loneliness can have a lasting impact on our physical well-being. According to scientists from the Brain Dynamics Lab, modern life is leading people toward greater isolation which can trigger many disorders. Their plan is to tackle loneliness with medication, and doing so, prevent the onset of harsher psychological problems that may follow.
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.
Researchers from Imperial College London have developed a new material that interacts with injured tissues to promote wound healing. It could change the way traditional medical materials interact with the body and revolutionize the way injuries are treated.
