By LAWRENCE K. ALTMAN, The New York Times, November 29, 2005


The World Health Organization's failure to meet a goal of treating three million H.I.V.-infected people by the end of this year owes to inadequate international coordination and lack of national leadership, a group of leading advocates for AIDS patients said yesterday.

Rural Water Worries Persist After Chinese Chemical Spill
By JIM YARDLEY, The New York Times, November 27, 2005


SIFANTAI VILLAGE, China, Nov. 26 - Liu Shiying lifted the metal cover off the clay cistern in a corner of the bare kitchen and lowered a tin ladle into what remained of her water supply. Then she raised a scoop to her mouth.

"Do you think it smells?" she asked on Saturday, not taking a sip. "We're still drinking this. It is our only choice."

Ms. Liu lives in one of the dingy villages on the outskirts of Harbin, the provincial capital whose water supply had been shut off for four days to prevent contamination from a chemical spill that dumped a huge tide of pollution into the city's main water source, the Songhua River.

Findings: The Grapefruit League
By BENEDICT CAREY, The New York Times, November 29, 2005


Athletes on a hot streak often describe warps in space-time that even Einstein did not anticipate: basketball hoops appearing as wide as hula-hoops, tennis balls that seem to move in slow motion, golf outings in which the cups seem as easy to hit as open manholes. "When you're hitting the ball, it comes at you looking like a grapefruit; when you're not, it looks like a black-eyed pea," the Red Sox slugger George Scott once said.

The changes in perception are apparently real, if sometimes exaggerated.

Vital Signs: Patterns: Research Finds Twins to Be the Slower Siblings
By NICHOLAS BAKALAR, The New York Times, November 29, 2005


Researchers in Scotland have found that twins have substantially lower I.Q.'s than their singleton siblings, based on a sampling of more than 10,000 Scottish children born in the 1950's.

The study, published online Nov. 18 in BMJ, the British Medical Journal, concludes that at least part of the explanation lies in the reduced prenatal growth and shorter gestation typical of twins.
