Scientists have found out exactly how an exercise-triggered molecule suppresses hunger signals in the brain, leading to weight loss. It could be harnessed as a therapeutic, providing the same benefit without the work it takes to produce it naturally.

It's an inconvenient fact that many drugs have to be administered in the form of a slow intravenous (IV) drip, as opposed to a single quick injection. That may be about to change, however, thanks to a new take on an existing "spray drying" technique.

How do you send drugs to specific parts of the body so they do their job and avoid causing side effects elsewhere? According to researchers at Stanford University, the answer is a combination of nanoparticles, a pulse of ultrasound, and sugar.

A subtle tweak in the way you walk – putting your toes in or out by a few degrees – could ease knee osteoarthritis pain and slow joint damage, according to new research that found personalized gait retraining can reduce strain on vulnerable cartilage.

Hospital meals have long been the butt of jokes, but new research shows they might actually pose a health risk, with low-quality diets failing to meet basic nutrition standards in hospitals and nursing homes.

We all know that injuries inside the mouth heal quicker than those on the outside of the body. Scientists have a new understanding of why, and believe that their findings could be used in wound treatments that reduce or even eliminate scarring.

More than a third of large animals that feast on dead animals are struggling to survive, and a new report from scientists warns that their downfall could present a serious risk to human life, with an uptick in zoonotic disease spread as a result.

When trying to remove life-threatening clots from blood vessels, current technologies are successful on only about half of the first attempts – if at all. A new surgical tool, however, is claimed to boost that figure to an astounding 90%.

The existence of orange cats dates back to the 12th century, but the DNA driving this color has been a mystery – until now. Scientists have solved the puzzle, finding a surprise variant that triggers ginger fur, one not seen in any other orange animal.

Tiny 3D organs connected themselves in a lab dish, forming a replica of the human pain pathway, in a new study. The discovery allows scientists to better understand chronic pain and offers an animal-free method of testing pain treatments.

Taking advantage of a unique public health policy in the UK, a new study has found that receiving the shingles vaccine reduces dementia risk by 20%. The findings bolster growing evidence linking the vaccine to lower numbers of dementia cases.

Injection needles can be scary, and the larger ones for longer-term medications are far more intimidating. Researchers have created a better way to deliver drugs into patients' systems, and it involves turning those drugs into tiny crystals.
