Living Organisms Depend on Bacterial Production of Critical Vitamin B12

All living organisms need a little bit of it to form red blood cells and DNA, as well as to build and support brain and nerve cells. But it's hard to come by: Humans don't make it. Animals don't make it. Plants don't make it.

Tireless Stem Cells Drive Continuous Renewal Across High Friction Human Intestines

Digestion is hard on the cells that line the human gut, and they are constantly being shed and replaced. This renewal is driven by a population of tireless stem cells. These stem cells can both replace the various types of intestinal cells that have been lost as well as renew themselves.

Malaria Infection Causes Permanent Damage to Resident Splenic CD163 Macrophages

Macrophages formed in the bone marrow can only assume the function of embryonal phagocytes, or "scavenger cells," to a certain degree according to a study by the University of Bonn and the Peter Doherty Institute for Infection and Immunity at the University of Melbourne.
