Diabetes can result from a loss of cells that produce insulin. Swedish researchers have now identified a molecule that helps stimulate the growth of new insulin-producing cells, and uncovered how it works, opening up new potential diabetes treatments.

The dysfunction of microglia in the central nervous system is linked to range of diseases, prompting a wide-ranging search for drugs that can alter their activity. New research, however, suggests we might already one such drug at our disposal.

Screen time is generally considered to be a negative influence on a child’s development but a new study makes a strikingly different case, presenting evidence that playing video games may actually boost a child’s intelligence.

Scientists exploring the potential of spider silk in next-generation cancer therapies have found yet another use for the natural material, using it to stabilize and enhance a cancer-killing protein known as the "guardian of the genome."

Better understanding the relationship between obesity and complications like type 2 diabetes can offer new ways to prevent adverse health effects faced by obese subjects, and a new study has found a new target likened to an "energy crisis" in fat cells.

Researchers have deployed drones carrying defibrillators to the sites of real-world cardiac arrests for the first time. On average, the unmanned aircraft arrived well ahead of ambulance crews, with the medical devices safely in tow.

A large study tracking some four million patients has linked adult ADHD diagnosis with a higher risk of a range of other diseases, including nervous system, musculoskeletal, respiratory, gut and metabolic conditions. Only arthritis wasn't correlated.

Researchers at Karolinska Institute in Sweden have made a breakthrough in the arms race that is cancer immunotherapy. The team has blocked a protein that silences an important tumor-suppressing protein, allowing the latter to get back to work.

Microneedle patches already show a great deal of promise as a painless alternative to hypodermic needles. A new one, however, could find use as a more effective means of treating serious bacterial infections of the skin.

New research has found one in five people have a genetic mutation that confers greater resilience to cold temperatures. The study shows people with a deficiency generating a skeletal muscle protein shiver less and hold higher core temperatures in the cold.

Cancer cells are very energy-hungry, which could be a potential weakness. Now, researchers have developed an experimental drug that blocks mitochondrial metabolism, starving cancer cells of energy while leaving healthy cells relatively unscathed.

Exactly how exercise could be directly helping the body fight cancer has been unclear. Now, a study led by researchers from Sweden’s Karolinska Institutet has discovered the way exercise can bolster the cancer-killing ability of certain immune cells.
