A new scanner can provide three-dimensional (3D) photoacoustic images of millimeter-scale veins and arteries in seconds. The scanner, developed by researchers at University College London (UCL), ...

The study suggests that bursting red blood cells, not blood clots, are the culprits. The microvasculature, the body’s network of tiny blood vessels, is critical for delivering oxygen and nutrients to ...

A team led by the University of Sydney has identified red blood cell rupture at dying endothelial sites as a primary driver of microvascular obstruction in COVID-19, bypassing the expected role of ...

The formation of blood vessels is a complex process involving the interplay of proteins and mechanic forces. In two studies, a research team has uncovered new mechanisms in blood vessel formation. The ...

3D printed blood vessels on glass that mimic blood vessel anatomy and the fluid dynamics of blood flow could be an invaluable tool in studying the causes of stroke, new research from a University of ...

Increase in blood pressure and intraocular pressure over time is associated with narrower and more twisted small blood vessels in the retina. Researchers assessed 2089 individuals from a Danish cohort ...

Miniature organs on a chip could allow us to do scientific studies with great precision, without having to resort to animal testing. The main problem, however, is that artificial tissue needs blood ...

When military personnel fire certain powerful weapons, they are exposed to a blast wave that sends blood surging from the body to the brain. This "tsunami in the body" is one way a blast can injure ...
