Scientists discover protein that allows safe recycling of iron from old red blood cells
Humans survive by constantly recycling iron, a metal that is an essential component of red blood cells, but which is toxic outside of those cells. More than 90 percent of the iron in an adult human's 25 trillion life-sustaining ...

Discovery of sexual mating in Candida albicans could provide insights into infections
Like many fungi and one-celled organisms, Candida albicans, a normally harmless microbe that can turn deadly, has long been thought to reproduce without sexual mating. But a new study by Professor Judith Berman and collea ...

Fruit fly studies guide investigators to misregulated mechanism in human cancers
Changes in how DNA interacts with histones—the proteins that package DNA—regulate many fundamental cell activities from stem cells maturing into a specific body cell type or blood cells becoming leukemic. ...

Humans, chimpanzees and monkeys share DNA but not gene regulatory mechanisms
Humans share over 90% of their DNA with their primate cousins. The expression or activity patterns of genes differ across species in ways that help explain each species' distinct biology and behavior.

How bacteria talk to each other and our cells
Bacteria can talk to each other via molecules they themselves produce. The phenomenon is called quorum sensing, and is important when an infection propagates. Now, researchers at Linköping University in Sweden are showing ...

Typical populations of bedbugs can cause harmful blood loss in humans, research finds
(Phys.org)—For years, bedbugs have been turning up in sometimes odd and random places, such as subways, movie theaters, dressing rooms and schools, but scientists believed that to flourish, the insects would need more frequent ...
