It's always good if the use of antibiotics can be avoided, to keep harmful bacteria from developing a resistance to them. A new wound-treatment spray could help, as it kills bacteria using peptides that occur naturally in our bodies.

Skin-applied microneedle patches are already used to painlessly deliver medication and detect chemicals in a patient's bloodstream. A new one, however, reportedly stops wounds from bleeding much more effectively than traditional bandages.

Researchers studying healthy centenarians have homed in on a gene mutation that plays a crucial role in maintaining cardiovascular health in old age. Across a series of experiments the researchers demonstrated how gene therapy could rejuvenate aging hearts.

It goes without saying that if someone has a blood clot in their brain, that clot should be cleared as soon as possible. An experimental new transducer could help, as it uses swirling waves of ultrasound to break up blood clots much faster than existing methods.

In a blow to researchers across the world, the only HIV vaccine currently in Phase 3 human trials has been deemed a failure. The experimental vaccine's failure turns the current research focus onto several other candidates only in early-stage human trials.

Moderna has announced promising results from its Phase 3 trial testing an mRNA vaccine for RSV in older adults. Data indicates the vaccine is nearly 84% effective at preventing moderate disease and the company expects to file for FDA approval this year.

Staphylococcus aureus is a common bacterium in humans, but it can turn nasty. A new clinical trial has shown that a probiotic can selectively cut populations of the bug in humans, reducing the risk of infection without the hazards of antibiotics.

A clinical trial has shown a new type of medical scan can identify specific adrenal gland nodules responsible for high blood pressure. The scan offers the first simple diagnostic tool for what is the cause of hypertension in up to 10% of people.

Researchers have discovered an old class of antipsychotic drugs may offer clues to a novel kind of treatment for type 2 diabetes. While the drugs may be directly repurposed, they could also be slightly modified to specifically target blood sugar control.

When someone suffers a heart attack, their heart is left permanently scarred and thus less capable of pumping blood. According to a new study, however, a protein injection could help undo such damage.

As is the case with so many other things, the sooner that Alzheimer's disease is detected, the more that can be done to slow its progress. An experimental implantable lens could help, by changing in appearance at the early stages of the illness.

In an ideal world, managing diabetes wouldn’t involve insulin injections but just popping a pill. Now a team of scientists has demonstrated an oral tablet that’s self-propelled by chemical “micromotors” to deliver insulin in the colon of rats.

Unlike normal skin, scar tissue doesn't contain any hair follicles. New research now indicates that when such follicles are transplanted into scar tissue, that tissue changes to become much more like uninjured skin.

Researchers at UCLA have developed a small sponge that can be implanted next to a tumor to help the body fight it. In tests in mice, the devices induced remission, prevented growth and spread of cancers, and increased survival times.

The FDA has approved a new drug for patients in the early-stages of Alzheimer's disease but growing concerns over its safety and real-world efficacy have led to division amongst researchers, with some suggesting it should not be authorized for wide use.
