Study shows how surface curvature drives cell migration

The curvature of a surface determines the migration behavior of biological cells. They preferentially move along valleys or grooves while avoiding ridges. These findings, published in the journal Proceedings of the National ...

Iron restriction keeps blood stem cells young, researchers find

As we age, our hematopoietic (blood-forming) stem cells (HSCs) become less able to produce new red and white blood cells and other vital blood components—contributing to chronic inflammation and accelerating the onset of ...

'Dynamic duo' defenses in bacteria ward off viral threats

Scientists at the University of Southampton have discovered that bacteria can pair up their defense systems to create a formidable force, greater than the sum of its parts, to fight off attacks from phage viruses. Understanding ...

Blood cell family trees trace how production changes with aging

Blood cells make up the majority of cells in the human body. They perform critical functions and their dysfunction is implicated in many important human diseases, from anemias to blood cancers like leukemia. The many types ...
