...hard to know what to make of the Hunter mess and of the turbocharging pharmaceuticals that so corrupt athletics now - all the potions to build up jocks with muscle mass and aggression and more red blood cells (and a bloated liver, maybe). One feels pained for Andreea Raducan, the 16-year-old Romanian gymnast who was stripped of her gold medal in the all-around competition because, it seems, her team physician had prescribed a cold remedy containing the stimulant pseudoephedrine. Was it fair to take the medal away when her intent seemed innocent? But what of the doctor...
DIED. JOHN HOLAHAN, 83, philanthropist, cereal executive and creator of Lucky Charms; in a car accident that also killed his wife Rosalind, 84; while going to visit their comatose 51-year-old daughter who was dying of liver cancer in Richfield, Minn. Holahan often told schoolchildren he created his "magically delicious" cereal during a 1963 brainstorm in which he cut up orange marshmallow peanuts and sprinkled them over Cheerios. Two days after the accident, daughter Shannon Kilkenny died...
...Gore, Jewish peacemaker. Not a title he sought, but it's not chopped liver...
...daunting task. A single enzyme in a liver cell may be controlled by as many as 14 different regulatory processes. Multiply that by thousands of interconnected chemical reactions operating simultaneously in billions of cells, and you've got one incredibly complex system. But Arkin knows that computer-chip designers manage similar levels of complexity. "Good engineers in the 1960s could probably understand all the circuitry that people had built," Arkin says. "But when integrated circuits were developed, that became impossible." There were just too many pieces to put together...
...cells, master cells with the ability to morph into any type of brain cell, depending on the chemical signals they receive as they grow. Early studies hint that they may even belong to a more primitive population of stem cells that can form anything from skin to blood to liver. Gage showed that a part of the hippocampus contains actively developing neural-stem cells; he further speculated that this regeneration may eventually be controlled by the timely addition or subtraction of a few key growth factors in the brain's chemical soup...
