Iron deficiency anemia is a condition in which the body does not have enough healthy red blood cells due to a shortage of iron. It is common among older adults, with possible causes including nutritional deficiencies, blood loss, taking certain medications, and poor absorption. The body uses iron in the production of red blood cells (RBCs), which...
Asking whether an age-associated disease is a part of normal aging is an exercise in boundary drawing. The very definition of an age-related disease as something distinct from aging is the result of past boundary drawing. Many of these boundaries are quite arbitrary. Aging is a complex phenomenon, and people like to lay taxonomies on top...

MIT biologists show that enlargement of blood stem cells restricts their ability to generate new blood cells during aging. MIT biologists have answered an important biological question: Why do cells control their size? Jette Lengefeld, a former postdoc in the lab of MIT Professor Angelika Amon.

Bone mineral density at the femoral neck bone in postmenopausal women decreased by an average of 10% during a 25-year follow-up, according to a new study from the University of Eastern Finland. Being the world’s hitherto longest follow-up of changes in bone mineral density in postmenopausal women, the study shows that bone loss after menopause...
