Scientist receives DoD grant to develop freeze-dried synthetic platelets

A Case Western Reserve University scientist, who has for more than a decade pioneered research into synthetic platelet substitutes, has been awarded a $3.8 million grant by the U.S. Department of Defense (DOD) to develop freeze-dried artificial platelets that can treat bleeding in wounded soldiers in the battlefield before they can be taken to a hospital.

Study solves longstanding mysteries about frogs

Frogs and toads are green for a very good reason - it makes them harder to see in their leafy environments. Good camouflage allows them to eat and not be eaten. But not all frogs have arrived at this life-saving greenness in the same way.

New technology generates immune response by delivering antigens to APCs in the spleen

Red blood cells do more than shuttle oxygen from our lungs to our organs: they also help the body fight off infections by capturing pathogens on their surfaces, neutralizing them, and presenting them to immune cells in the spleen and liver.

Genetic 'memory' of ancestral homelands helps organisms adapt to environmental change

Organisms carry long-term "memories" of their ancestral homelands that help them adapt to environmental change, according to a new study that involved raising chickens on the Tibetan Plateau and an adjacent lowland site.

Selectively eliminating leukemic and hematopoietic stem cells

Acute myeloid leukemia is an aggressive cancer of the blood-forming system. It affects the hematopoietic stem cells, or blood stem cells, of various white blood cells and of the red blood cells and platelets.

Small Red Blood Cells Could Indicate Cancer

Having abnormally small red blood cells, a condition known as microcytosis could indicate cancer, according to new research led by a University of Exeter.
