Page 275 The artificial pacemaker generates electrical signals (also called impulses) to keep the heart beating. Two Canadian surgeons, Wilfred Bigelow and John Callaghan, and a Canadian electrical engineer, Jack Hopps, invented this life-saving device. How did the amputation of frostbitten fingers lead to the invention of the artificial pacemaker? What improvements to this device have been made to its original design?
Excellent article outlining Wilfred Bigelow's contribution to medical science and the story behind the invention of the artificial
pacemaker. (

This website presents a timeline of electrocardiography, beginning in the 17 century. Hoff, Bigelow and Callaghan are mentioned in 1950,
but there is fascinating information on the 350 years previous to their invention of the cardiac pacemaker and also the innovations in this area up to
present time. (

Page 286 Many serious athletes choose to train at high altitudes, where the air is thinner and the partial pressure of oxygen is lower. What benefit does this provide for athletes? There are several technological methods for achieving the same benefit. What are they, how do they affect the body, and why are they illegal?
This is an interesting article on different types of performance enhancements used by athletes, including the use of Erythropoietin (EPO)
to mimic the effects of high altitude training. (

Page 291 Advances in the treatment of leukemia include the use of blood from umbilical cords and the transplanting of stem cells. Stem cells are cells from which specialized cells of the body develop. How do these two treatment options work? What are the controversies associated with them?
The Lasker Foundation: 2005 Albert Lasker Award for Basic Medical Research to Ernest A. McCulloch and James E. Till, Canadian doctors who
pioneered stem cell research. The award citation details the research Dr. McCulloch and Till began in the 1950s as they discovered stem cells and how they
work. (

Peanuts are not actually nuts, but the seeds of a member of the legume family. Peanuts are one of the most allergenic foods, and the reaction they cause can be fatal. When people who are highly sensitive to peanuts are exposed either directly or indirectly to them, they may experience anaphylaxis. What is anaphylaxis, and how is it treated? What advances have been made to improve our understanding and approaches to treating peanut allergies?
This article summarizes seven recently published scientific articles about advances in treatment and causes of peanut
allergies. (
