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.
