It goes without saying that the earlier someone can be warned of an impending heart attack or stroke, the better. A new skin patch could provide such warnings, by sending ultrasound pulses into the wearer's body.

Not only are surgical scars unsightly, but their limited elasticity can also reduce the patient's range of motion. There may be new hope, though, as a recent study has shed light on how a therapeutic peptide could drastically reduce such scarring.

Scientists have made a promising discovery relating to MS, demonstrating how neutralizing a specific protein can selectively temper the inflammation that drives the disease, which makes it an ideal target in the ongoing pursuit of a cure.

Researchers in Germany have developed a new method to treat viral infections by making traps. The team folded DNA into nano-capsules with specialized binding points inside them, which could grab hold of viruses and render them inert.

Chronic wounds can be very difficult to treat, potentially leading to amputations or even death due to associated infections. A new dressing, however, may be able to heal such wounds while remaining much less expensive than other materials.

Radiotherapy is one of the best treatments we have against cancer, but there's room for improvement. Now, researchers in Japan have developed nanoparticles that can penetrate tumors and kill them from within, after being activated by external X-rays.

During surgery or traumatic injury, quickly stopping bleeding saves lives. Now, scientists have recruited an unlikely ally to that cause – snake venom, which forms the basis of a new “super glue” that halts bleeding in seconds after light activation.

The earlier cancer is detected, the better. MIT scientists have developed a diagnostic system that can be performed as a urine test to detect the presence of cancer, and if a positive is returned, a follow-up test can locate where it is in the body.

New research has demonstrated how a drug candidate built off a molecule in funnel web spider venom can stop the "death signal" that results from a heart attack, potentially providing first responders with a powerful new way to intervene.

For many people with arthritic knees, a surgical procedure known as a high-tibial osteotomy (HTO) often brings relief. Thanks to 3D printing technology, however, it could soon be even more effective – and also safer to perform.

Researchers have demonstrated, for the first time, a brain implant turning neural activity into full words. The first participant in the trial, a paralyzed man, can now speak with a vocabulary of 50 words by simply thinking about vocalizing words.

Scientists at Oxford have uncovered a mechanism behind why people with diabetes have an increased risk of cardiovascular diseases. High blood sugar levels seem to “reprogram” stem cells so that the immune cells they produce become more inflammatory.
