James Herrick, a Chicago doctor, was the first to describe sickled red blood cells in a patient of African descent.

Myosin proteins tug on the cell membrane, giving an erythrocyte its distinct shape.

Optical engineers have developed a portable field microscope that could aid the diagnosis of diseased cells.

These fossilized red blood cells (right), found in an ancient, blood-engorged Amblyomma tick (left), likely belonged to primates.

Artemisinin targets multiple parasite proteins after being activated by the iron in heme cofactors.

A new study is rewriting 50 years of biological dogma by suggesting that mature blood cells develop much more rapidly from stem cells than previously thought.

Researchers report finding evidence of red blood cells and proteins in 75-million-year-old dinosaur fossils.

A microfluidic device can safely remove glycerol from thawed red blood cells in minutes, potentially making frozen blood more feasible for routine transfusions.

Researchers have developed fast-dissolving particles that may one day prevent organ damage or death by instantly infusing oxygen into the blood.
