- Amyloid-beta alters red blood cell oxygen handling in laboratory study ()
Published October 18, 2026. A study published in Cell Death Discovery on October 17 examines how amyloid-beta peptides affect oxygen handling by human red blood cells. The findings suggest a possible blood-based contribution to oxygen abnormalities associated with Alzheimer’s disease. In laboratory experiments, binding of Aβ42 and its modified isoAβ42 form reduced hemoglobin’s oxygen affinity […]
- How Scientists Revived Organs in Pigs an Hour After They Died ()
Oxygen is the elixir of life. Stop its flow—during a stroke, heart attack, or death—and the body’s tissues respond in a biological storm that eventually leads to their death. It’s not great for organ transplants. Most donated organs struggle to survive beyond death. Deprived of oxygen, they rapidly lose their function. Cells turn into acidic, […]
- The lugworm, frequently used as bait, could save human lives ()
For centuries, the only use humans found for the lugworm — dark pink, slimy and inedible — was on the end of a fish hook. But the invertebrates’ unappreciated status is about to change. Their blood, say French researchers, has an extraordinary ability to load up with life-giving oxygen. Harnessing it for human needs could […]
