Tiny particles that have the bendable flexibility of red blood cells can skirt pass the body’s defenses and circulate in the body longer than harder, rigid ones, a new study shows. These particles can ...

Nano-sized particles released by red blood cells reduce inflammation and fat deposition in immune cells, potentially paving the way for new methods of treating atherosclerosis. Atherosclerosis is a ...

Representative light microscopy images of carbonaceous (black) particles adherent to red blood cells (red arrows) from healthy volunteers. Each image is from a different adult volunteer. Researchers ...

Scientists have developed synthetic particles that closely mimic the characteristics and key functions of natural red blood cells, including softness, flexibility, and the ability to carry oxygen.

WHEN red rain fell over southern India in 2001 it was sensationally suggested that the red particles in the rain could be alien microbes. Now, after weeks of analysis at two labs in the UK, ...
