Imagine a device that lets people with diabetes use an app to give themselves a boost of insulin when they need it, without an injection. A prototype device can do just that, using electricity to control gene expression in encapsulated beta cells.

In organ transplants, rejection by the recipient's immune system is a risk. Now researchers at Yale have discovered a molecule that plays a role in triggering a slow-acting type of rejection, which could be blocked to give patients a better outlook.

Scientists at Harvard University and Singapore’s Nanyang Technological University have uncovered a pair of molecules with the ability to boost dopamine production in mice with Parkinson’s disease, greatly improving their motor function as a result.

How cancer develops is a complex puzzle, involving untold moving parts and chemical reactions. Now, scientists have found how two of these pieces work together to prevent cancer forming, which could unlock new types of cancer treatments.

A trial testing a drug designed to prevent HIV infection has been cut short due to a combination of positive early data and disruptions caused by COVID-19. The analysis found a single injection every eight weeks offers protection from HIV infection.

Scientists may have uncovered a powerful new tool in the fight against glioblastoma, the most aggressive type of brain cancer. An already-approved malaria drug was found to boost the effectiveness of existing treatments in mice.

Not only do ticks suck your blood, but they're able to do so for a long time, undetected. Scientists have now synthesized the protein that lets them get away with it, and it may have life-saving medical applications.

As some readers may already know, in-ear stimulation of the vagus nerve can help relieve pain in other parts of the body. Thanks to new research by Austrian scientists, such treatments could soon be more effective than ever.

An international team of scientists has developed technology that could detect diabetes-induced blindness in its early stages, using a smartphone as the basis for a low-cost diagnostic method that could greatly improve care in developing regions.

Scientists at Pennsylvania State University and Stanford University are reporting a breakthrough that could greatly improve on methods to detect kidney stones, demonstrating a novel type of urine test that can return results in just 30 minutes.

In future, many diseases may be treated by tiny robots delivering drugs. Taking inspiration from white blood cells, researchers from the Max Planck Institute have unveiled a new micro-robot design that can move against the current of blood flow.

A new study is suggesting signs of the disease ALS may be detectable in teeth, decades before the onset of any symptoms. The research points to a dysfunction in metabolizing metals as a possible factor in the onset of this still mysterious disease.
