Arteries carry oxygenated blood away from your heart. They have thick walls and a muscular layer that keeps your blood moving. Arteries can be as wide as a nickel (about two centimeters). They are the ...

Prellis Biologics has brought the science fiction dream of printing human organs for transplant a step forward by developing a fast, high-resolution 3D printing technique that can produce living ...

While medical centers use ultrasound daily, so far this technology has not been capable of observing body tissues at the scale of cells. Physicists have now developed a microscopy technique based on ...

Taking a magnifying mirror to the face is never a fully positive experience—especially when you sit under the fluorescent bathroom lights in hopes of a satisfying extraction, and instead come across ...

Broken blood vessels on the face, or spider veins, are enlarged capillaries that occur just beneath the surface of the skin. Genetics, sun exposure, sneezing, and many other factors can cause them.

Ultrasound is one of the most widely used imaging techniques in medicine, but up until recently it hardly played a role in imaging the tiniest structures of our bodies such as cells. “Clinical ...

Researchers from the University of Technology Delft, the Netherlands Institute for Neuroscience and Caltech have developed a microscopy technique based on ultrasound to reveal capillaries and cells ...
