Running extreme distances may strain more than just muscles and joints. New research suggests ultramarathons can alter red blood cells in ways that make them less flexible and more prone to breakdown, ...

Making a living brain transparent and watching its neurons fire without disturbing their function-sounds like science fiction ...

The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural ...

Abundant and persistent, red blood cells have a lifetime of about four months in the human body and travel to every organ and tissue. They could soon be leveraged to transport more than oxygen and ...

Scientists have long known that people living at high altitudes, where oxygen levels are low, have lower rates of diabetes than people living closer to sea level. But the mechanism of this protection ...

After a long trail race, some of your red blood cells may not bend the way they should. That matters because red blood cells have a tight job description.

(Jordan Siemens/Stone/Getty Images) Research has shown that living at higher altitudes lowers your risk of developing diabetes, but scientists haven't been able to pin down why that is – until now. A ...

Tiny plastic particles, from the micro- to nanoscale, have been routinely detected in water, soil, air, aquatic species, and humans in recent years. As concerns grow over their potential impact on the ...

Editor’s note: Every year, hundreds of undergraduates at the University of Delaware pursue research under the guidance of a faculty mentor, especially during the summer months. Such experiences ...

For patients with a rare type of blood cancer, treatment might finally be coming out of the Dark Ages. People with the chronic condition polycythemia vera make too many red blood cells, thickening ...

Red blood cells normally cannot move on their own; they lack any of the cell structures needed for movement. Instead, they deliver oxygen throughout the body by going with the flow of blood. So, when ...
