The final puff: Can New Zealand quit smoking for good?
Smoking kills. Ayesha Verrall has seen it up close. As a young resident physician in New Zealand’s public hospitals in the 2000s, Verrall watched smokers come into the emergency ward every night, struggling to breathe with their damaged lungs. Later, as an infectious disease specialist, she saw how smoking exacerbated illness in individuals diagnosed with tuberculosis and HIV/AIDS. She would tell them: “The best thing you can do to promote your health, other than take the pills, is to quit smoking.” Verrall is still urging citizens to give up cigarettes—no longer just one by one, but by the thousands. As New...

You hopefully wouldn't smoke 100 cigarettes in 60 minutes -- that's five entire packs of so-called cancer sticks.  If you casually dabble with hookah, however, you might not bat an eye at an hour-long smoking session. New research shows lots of young people don't know that 100 cigarettes and an hour of hookah are about equal in terms of the amount of smoke inhaled -- and therefore in the damage they can cause to a person's health, including increased risk for heart disease, cancers, stroke, blood clots and death, to name a few. A 2005 report by the World Health Organization found that hookah smoker...

Stem Cells for Cell-Based Therapies
The world of stem cells We know the human body comprises many cell types (e.g., blood cells, skin cells, cervical cells), but we often forget to appreciate that all of these different cell types arose from a single cell—the fertilized egg. A host of sequential, awe-inspiring events occur between the fertilization of an egg and the formation of a new individual: Embryonic stem (ES) cells are also called totipotent cells. The first steps involve making more cells by simple cell division: one cell becomes two cells; two cells become four cells, etc. Each cell of early development is undifferentiated; that is, it is...
