The blood of young and old people differs. In an article published recently in the scientific journal Blood, a research group at Lund University in Sweden explain how they have succeeded in rejuvenating the blood of mice by reversing, or re-programming, the stem cells that produce blood.

Scientists have confirmed that the pathogen that causes Lyme Disease -- unlike any other known organism -- can exist without iron, a metal that all other life needs to make proteins and enzymes. Instead of iron, the bacteria substitute manganese to make an essential enzyme, thus eluding immune system defenses that protect the body by starving pathogens of iron.

What happens if you get a blood transfusion with the wrong blood type? Even though a patient's own blood type is the first choice for blood transfusions, it's not always available at the blood bank. Try to save some patients' lives and learn about human blood types!

A selection of articles to further your understanding of the production and function of blood within the human body; the views about blood that predominated for centuries and the medical practices that such views helped to engender; the advancements in the medical use and collection of blood brought on by war, most notably World War II; modern-day techniques for the collection, storage, and use of blood. Some articles are augmented by video clips from RED GOLD: THE EPIC STORY OF BLOOD. (The free RealPlayer plug-in is required to view the clips.)

Bonnie Bassler discovered that bacteria "talk" to each other, using a chemical language that lets them coordinate defense and mount attacks. The find has stunning implications for medicine, industry -- and our understanding of ourselves. Bonnie Bassler studies how bacteria can communicate with one another, through chemical signals, to act as a unit. Her work could pave the way for new, more potent medicine.
