A large new study has found that healthy older adults taking a long-term low dose of aspirin may be at increased risk of developing anemia. The researchers say their findings suggest that these patients may need regular monitoring.

Scientists have discovered a gene variant that causes a common type of high blood pressure – and found a cure. A simple surgical procedure saw patients with previously severe hypertension needing no drugs or further treatment for years afterwards.

As a way of treating hemophilia, researchers have, for the first time, delivered gene therapy directly into the livers of baboons without using a viral carrier. The study shows it is safe and effective and may lead to a new treatment for the disease.

MIT scientists have developed a synthetic system that can stem internal bleeding, to help save lives after a traumatic injury. Two components come together at a wound to form a clot, without doing so elsewhere in the body where it might be dangerous.

Bears don't move much all winter long, but people are advised to get up frequently during a long flight to prevent blood clots. A new study uncovers why this discrepancy exists, and how it might lead to safer replacements for blood thinners.

This internal fuel cell powered by excess glucose in the blood works in tandem with engineered beta cells that can produce and secrete insulin on command. It could spell a new level of autonomy in treatment for type 1 diabetes sufferers.

For studies on insect-borne diseases, many a human has sacrificed an arm in a tank full of mosquitos. Now, a new artificial skin filled with real blood might spare humans the itchy bites, while providing a greater insight into mosquito behavior.

In what sounds like sci-fi, transfusions of youthful blood can improve the health of older people. A new study has found that an existing arthritis drug can effectively rejuvenate blood stem cells, mimicking the benefits of young blood transfusions.

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.

Scientists believe they have discovered how a common disease called shingles can increase a person's risk of stroke. The research reveals how viral infections can be reawakened after lying dormant for years and cause health issues beyond acute disease.

When glassfrogs sleep, they turn their bodies transparent in order to evade predators. Scientists have now discovered that they do so by moving their red blood cells into their liver – and the finding could have implications for human medicine.

Engineers have developed an electronic patch capable of monitoring biomolecules in deep tissue, which they say can be used to detect a range of life-threatening conditions, including organ dysfunction and malignant cancers.
