...this week in the Archives of General Psychiatry, scientists describe for the first time a set of genes, about 100 in all, that seem to predict how well a smoker will respond to two different types of quitting programs - nicotine replacement or bupropion (Zyban). Nicotine-replacement methods, including the patch, pill and gum, work by weaning the smoker off nicotine gradually, usually over a period of weeks or months. Bupropion, on the other hand, is an antidepressant, which does not contain nicotine; instead, it works to curb nicotine cravings by interfering with the reward circuit in the brain, where addictions...
Horseback riding and the swampy tidal flats of Singapore aren't images that go hand in hand, but half a mile down a deserted road - in the middle of a tropical rainforest - lies a small patch of England's Berkshire, complete with paddocks, stables and riding trails crisscrossing the lush hills.

The diagnosis: Stage 2A melanoma, an invasive form of skin cancer that claims the lives of up to 34% of those diagnosed within 10 years. Doctors also made an incision down his left cheek to remove lymph nodes in his neck in case the cancer had spread; they found it had not. The surgery left a large scar, and for weeks McCain retreated from public view to recover...
...Israel marks its 60th birthday, its citizens would seem to have plenty to celebrate. Situated on a patch of stony land, democratic Israel has endured the ravages of war and terrorism and an assortment of enemies sworn to destroy it. Israelis have managed to revive Hebrew, a 4,000-year-old language, and turn it into a vibrant instrument of elegant novelists and growling rappers. In cities like Tel Aviv and Haifa, the high-tech industry has produced years of robust growth and fostered a culture of creativity and inventiveness that is the envy of the Middle East...
