A new study has identified a subset of microglia, the brain's immune cells, and their important role in brain development and cognition that could pave the way for new treatments for neurodegenerative conditions like Alzheimer’s disease.

In new research, the presence of a blood-based sugar molecule helped predict the onset of Alzheimer's up to a decade before symptoms appeared. The protocol could join others in spotting the condition early and slowing its progression.

The health benefits of caffeine have been studied for years. Researchers have examined the genes associated with caffeine metabolism to see whether blood caffeine levels affect body fat levels and risk of type 2 diabetes and cardiovascular disease.

Scientists investigating the way a certain type of fat behaves in response to cold have made a discovery that could have ramifications for cancer treatment, showing how tumor cells can be starved of a vital fuel source they need to thrive.

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.
