Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new UCL-led study, the first of its kind in humans. Scientists believe the discovery, published in the Journals of Gerontology, could signal the dawn of new affordable home-based eye therapies, helping the millions of people globally with naturally […]
Killing coronavirus with handheld ultraviolet light device may be feasible
A personal, handheld device emitting high-intensity ultraviolet light to disinfect areas by killing the novel coronavirus is now feasible, according to researchers at Penn State, the University of Minnesota and two Japanese universities. There are two commonly employed methods to sanitize and disinfect areas from bacteria and viruses — chemicals or ultraviolet radiation exposure. The […]
Popcorn: The snack with even higher antioxidants levels than fruits and vegetables
Popcorn’s reputation as a snack food that’s actually good for health popped up a few notches as scientists recently reported that it contains more of the healthful antioxidant substances called “polyphenols” than fruits and vegetables. They spoke at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), in San Diego on March […]
Drink coffee after breakfast, not before, for better metabolic control
A strong, black coffee to wake you up after a bad night’s sleep could impair control of blood sugar levels, according to a new study. Research from the Centre for Nutrition, Exercise & Metabolism at the University of Bath (UK) looked at the effect of broken sleep and morning coffee across a range of different […]
Eating dried fruit may be linked with better diet quality and health markers
Don’t be afraid to toss a handful of raisins or dried apples in your Thanksgiving stuffing this year — a new Penn State study has found that dried fruit may be connected with better health. The researchers found that people who ate dried fruit were generally healthier than those who did not, and on days […]
SARS-CoV-2 mutations do not appear to increase transmissibility
None of the mutations currently documented in the SARS-CoV-2 virus appear to increase its transmissibility in humans, according to a study led by UCL researchers. The analysis of virus genomes from over 46,000 people with COVID-19 from 99 countries is published today in Nature Communications. First and corresponding author Dr Lucy van Dorp (UCL Genetics Institute) […]
Zinc helps against infection by tapping brakes in immune response
New research suggests that zinc helps control infections by gently tapping the brakes on the immune response in a way that prevents out-of-control inflammation that can be damaging and even deadly. Scientists determined in human cell culture and animal studies that a protein lures zinc into key cells that are first-responders against infection. The zinc […]
Healthy sleep habits help lower risk of heart failure
Adults with the healthiest sleep patterns had a 42% lower risk of heart failure regardless of other risk factors compared to adults with unhealthy sleep patterns, according to new research published today in the American Heart Association’s flagship journal Circulation. Healthy sleep patterns are rising in the morning, sleeping 7-8 hours a day and having no […]
Temperature checks not very effective in detecting COVID-19 infection in symptom screenings
Temperature and COVID-19 symptom checks like the ones used at schools and doctor’s offices have again proved inadequate for spotting coronavirus infections and preventing outbreaks. A study of Marine recruits found that despite these measures and strict quarantines before they started training, the recruits spread the virus to others even though hardly any of them […]
Zinc Citrate Absorption Superior to Oxide
According to new research published online in The Journal of Nutrition*, zinc citrate showed superior absorption compared to zinc oxide and was on pair with the nutritional benchmark zinc gluconate. Despite of the benefits of zinc citrate over soluble zinc salts concerning zinc content and more neutral taste, no human absorption data was available to […]
