MIT scientists have developed a new technique to jump-start the body's immune system with the help of injured cancerous cells, with the approach shown to be capable of completely eliminating tumors in mouse models of the disease.

While there are already eye implants that allow the blind to see simple patterns, Spanish scientists have recently had success with a different approach. They bypassed the eyes, producing perceivable images by directly stimulating the visual cortex.

The hormone leptin is central to the way our bodies regulate appetite. A new study has revealed some of the molecular machinery behind its functioning, and shown how the loss of a key protein can drive insatiable appetites and obesity in mice.

Currently, most diabetics have to check their blood glucose levels by performing finger-prick blood tests, or via implanted sensors. An experimental new device, however, could someday do the job while simply adhered to the surface of the user's skin.

Living with pain can be very difficult, especially since heavy-duty pain relievers typically have unwanted side effects, and can be habit-forming. An experimental new treatment, however, gets around those limitations by using implanted electrodes.

The interplay between high blood pressure and brain health is one scientists continue to shed new light on, with a new study finding even those with readings at the higher end of the normal recommended range can be at risk of premature brain aging.

Earlier detection of dementia could open up far more effective ways to treat and manage the condition. A new study has pinpointed "harbinger" molecules that could predict onset two to five years in advance, and may provide new targets for therapies.

By using a compound derived from a Himalayan fungus and used for centuries in Chinese medicine as a jumping off point, scientists have developed a new chemotherapy drug with powerful anti-cancer effects.

For decades surgeons have been using deep brain stimulation to treat severe Parkinson's disease. Now researchers have found a way to deliver it more precisely, resulting in the benefits lasting four times longer in animal models.

Scientists have demonstrated a new way to fight antibiotic-resistant superbugs by pitting bacteria against each other. The team engineered a common bacteria to safely colonize medical implants, then produce enzymes that dissolve superbug biofilms.

Scientists at Australia's La Trobe University have been developing a new microscope slide that presents cancer cells in color without the need for stains and dyes, and used it to detect breast cancer as part of an early trial.

A new study has explored how the blood-brain barrier might be shored up through the use of an existing anti-cancer drug, with the authors demonstrating some promising results around reversing cognitive decline in mice.
