Scientists have developed a method to convert human urine into a solid mineral found in bones and tooth enamel. The research, funded by the U.S. Defense Advanced Research Projects Agency (DARPA), uses yeast to break down urine into hydroxyapatite — a form of calcium found in bones and used in dental implants. Hydroxyapatite is useful…
Scientists have systematically investigated the genetic effects of chemotherapy on healthy tissues for the first time. Researchers from the Wellcome Sanger Institute, the University of Cambridge, Cambridge University Hospitals and the NHS Foundation Trust and their colleagues analyzed the genomes of blood cells from 23 patients of different ages who were undergoing different types of…
Most people around the world wash their hair once or twice a week, regardless of the season. However, experts say this hair-washing routine may not be suitable for the summer. Dr. Pallavi Bradshaw, Deputy Chief Medical Officer at AXA Health Insurance, says that during the intense summer heat, it is necessary to wash your hair…
Recently, parents of young children have raised concerns about recurring symptoms such as high fever, weakness, and vomiting. In an interview with NEWS.am, Nerses Grigoryan, a physician-epidemiologist at the Department of Epidemiology of Infectious Diseases at the National Center for Disease Control and Prevention (NCDC), noted that intestinal infectious diseases tend to become more active…
New research has found that silence is not merely the absence of sound, but an active force that can transform the brain and enhance overall health. After just three days of intentional silence, physical and functional changes occur in the human brain that are comparable to those produced by long-term meditation or cognitive training. A…
American scientists from the University of California, San Francisco, have discovered an unexpected link between an aggressive form of bladder cancer and ovarian tumors. This discovery enabled them to apply advanced immunotherapy methods to treat a type of cancer that previously could only be addressed through surgery — and not always successfully. The study was…
A new study published in JAMA Network Open suggests that swapping car keys for a bicycle helmet may reduce the risk of dementia and Alzheimer’s disease. Scientists have found that regular cycling may even help increase the size of the brain region responsible for memory. They analyzed data from nearly 480,000 people who reported their…
Studies have shown that high consumption of ultra-processed foods is linked to several diseases, including diabetes, cardiovascular and cerebrovascular conditions, as well as dementia. A recent international study found a correlation between the consumption of ultra-processed foods and brain structure. The study, based on data from the UK Biobank and involving nearly 30,000 middle-aged participants…
Scientists at the Swiss Federal Institute of Technology in Lausanne have developed a new technology to create DNA molecules that bind to viral proteins more precisely and tightly than traditional antibodies. Their work is published in Nature Nanotechnology. These are aptamers—short strands of DNA or RNA that can selectively bind to specific molecules. Used in…
Switching from a high-fat diet to a low-fat diet may slow the development of precancerous changes in the pancreas, according to a study published in the Journal of Nutrition (JN) by researchers at the University of California, Davis. In the experiment, rodents were divided into three groups: one received a high-fat diet, another a low-fat…
