A randomized controlled trial of 2,275 women in Kenya showed that a single dose of the human papillomavirus (HPV) vaccine was highly effective. The current standard for women is a three-dose regimen. Dr. Ruanne Barnabas,  principal investigator in the trial, said the trial results could help the World Health Organization reach its goal to have 90% of 15-year-old […]

A key ingredient is missing from all sunscreens and anti-aging creams, and our skin will be far better protected from the damaging effects of the sun once this rich source of natural photoprotection has been added. This is the finding of a new study into sun-related skin aging carried out at the UK’s University of […]

A proposal to provide monthly payments to most U.S. parents, similar to those under the pandemic relief program, would likely worsen poverty for children of single mothers, a study has found. The Family Security Act proposed by Sen. Mitt Romney (R-Utah) aims to cut child poverty by a third by providing most parents with monthly […]

One way in which scientists are studying how the human body grows and ages is by creating artificial organs in the laboratory. The most popular of these organs is currently the organoid, a miniaturized organ made from stem cells. Organoids have been used to model a variety of organs, but brain organoids are the most […]

Fighters who rapidly cut weight before bouts are at a higher risk of suffering concussions or being misdiagnosed with head trauma, researchers have revealed for the first time. More than 60 per cent of athletes in combat sports like boxing and mixed martial arts (MMA) revealed their symptoms were worse after dehydrating themselves to make […]

In the fall of 2020, before vaccines were readily available, the Canadian Longitudinal Study on Aging (CLSA) surveyed nearly 24,000 middle-aged and older adults to test their willingness to get vaccinated. The new study from McGill and McMaster and Universities, published recently in the American Journal of Epidemiology, provides insight into the factors that may lead […]

Psilocybin fosters greater connections between different regions of the brain in depressed people, freeing them up from long-held patterns of rumination and excessive self-focus, according to a new study by scientists at UC San Francisco and Imperial College London. The discovery points toward a general mechanism through which psychedelics may be acting therapeutically on the […]

A new spin on one of the 20th century’s smallest but grandest inventions, the transistor, could help feed the world’s ever-growing appetite for digital memory while slicing up to 5% of the energy from its power-hungry diet. Following years of innovations from the University of Nebraska–Lincoln’s Christian Binek and University at Buffalo’s Jonathan Bird and […]

A new study by Florida Atlantic University researchers is literally shedding “light” on a way to improve the health of endangered green sea turtles (Chelonia mydas) prone to a disease called fibropapillomatosis. Affecting about 60 percent of sea turtles in some sub-populations, juveniles are most susceptible to this disease that causes the growth of large debilitating tumors […]

Best known therapeutically as a treatment for bipolar disorder, lithium has long intrigued researchers with its potential age-defying properties. The element has been shown in lab experiments to extend the lifespan of fruit flies and roundworms, while observational studies have suggested tap water naturally laced with trace amounts of lithium might improve human longevity. Researchers […]
