Melanoma is a common type of skin cancer – it is pretty much the reason why you have to put sunscreen on every time you leave the house. Melanoma can develop very rapidly, but scientists at the University of Queensland have now found a way to put the brakes on […]

Tasmanian tree skinks, as the name suggests, are lizards native to Tasmania. They live in a huge variety of habitats – from rocky coastlines to actual trees. They eat insects, spiders and sand hoppers, while sometimes enjoying an occasional amphipod. Now scientists at the University of Tasmania found that Tasmanian […]

COVID-19 is a common pandemic disease. In fact, it is likely that you know several people who had it or you had it yourself. After you get better from this infection, your body’s immune system knows how to protect you from COVID-19 for quite some time. But how long does […]

Regular physical activity has positive effects on children's developing brain circuits, finds a Boston Children's Hospital study using neuroimaging data from nearly 6,000 early adolescents. Physical activity of any kind was associated with more efficiently organized, flexible, and robust brain networks, the researchers found. The more physical activity, the more “fit” […]

Salk research shows how to optimize the production of insulin-producing cells from stem cells. Type 1 diabetes, which arises when the pancreas doesn’t create enough insulin to control levels of glucose in the blood, is a disease that currently has no cure and is difficult for most patients to manage. […]

Salk research reveals clues about molecular changes underlying muscle loss tied to aging. One of the many effects of aging is loss of muscle mass, which contributes to disability in older people. To counter this loss, scientists at the Salk Institute are studying ways to accelerate the regeneration of muscle […]

Young infants show strong immune responses to SARS-CoV-2, new research has found. In particular, compared with adults, young infants produce relatively high levels of antibodies and immune cells that can specifically protect against COVID-19. The study led by academics and paediatricians at the University of Bristol and Bristol Royal Hospital […]

Throwing out one’s back is a universal, albeit clichéd, a sign of middle age. What’s less common is 50-year-old men with the fragile bone strength of men in their 80s. Researchers at Michigan Medicine found a subset of middle-aged men with cerebral palsy is up to 5.6 times more likely […]

By making a game out of getting their daily steps, new research points to the possibility that people with diabetes could be nudged toward increasing their physical activity, with changes lasting for a full year. Since many now use apps or other digital means to manage their diabetes, this program […]

It’s often cancer’s spread, not the original tumour, that poses the disease’s most deadly risk. “And yet metastasis is one of the most poorly understood aspects of cancer biology,” says Kamen Simeonov, an M.D.-Ph.D. student at the University of Pennsylvania Perelman School of Medicine. In a new study, a team led by Simeonov and School of […]
