Bats modify their red blood cells to become thicker and ... This change might be slowing down the cells as they pass through capillaries in the muscles and lungs, making them highly efficient ...

The circulatory system consists of one heart, five liters of blood, and approximately 96,000 kilometers of blood vessels, responsible for transporting nutrients and waste throughout the body.

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 ...

Cerebral microbleeds are tiny areas of bleeding in the brain, often found in older adults or people with conditions like high ...

Red blood cells for example, have no nucleus, so they can hold more oxygen. They're also biconcave or disc-shaped to absorb oxygen more quickly and rounded to flow easily through tiny capillaries.

Contrary to what you likely learned in school, ferrying oxygen isn’t the only function of red blood cells. In a study published today (October 20) in Science Translational Medicine, researchers show ...

These rods cause a person's red blood cells to take on a deformed ... and they also tend to clog capillaries, causing an affected person's blood supply to be cut off to various tissues, including ...

In addition to revealing cells, the team used ultrasound and microbubbles as probes circulating in the blood stream to detect brain capillaries. Heiles: “To our knowledge, nonlinear sound sheet ...

Researchers from the University of Technology Delft, the Netherlands Institute for Neuroscience and Caltech have developed a ...
