...team visited 15 Indian specialty stores in the Boston area and purchased 71 cultural powders and 86 spices and food products. About 25% of the food items, including spices such as cardamom, fenugreek and chili powder, contained more than 1 microgram of lead per gram of product. About 65% of the ceremonial powders, including sindoor, which is used as a symbol of marriage, contained the same amount. Those levels are below the E.U.'s acceptable threshold of 2 to 3 mcg/g of lead, but the study's authors say that regardless of the amount, the presence of lead in these...

...have injected Atlantic bluefin females with synthetic hormones to trigger the fish's egg-laying response. This year, the team helped create some 150 million bluefin eggs, of which they took about 3 million to try to hatch. Of those, "maybe 50 [will] survive to the weight of one gram, or about 50 days [old]," says Aurelio Ortega, a biologist on the project. "We're still a long way off. Even five years would be very optimistic...
...poses a threat to the ozone layer is not new, but the Science study is the first comprehensive look at the exact concentrations and consequences of the gas. The investigators found that although N2O is only one-sixtieth as dangerous to the ozone layer as CFCs on a gram-by-gram basis, the sheer amount of N2O - each year nearly 1 billion metric tons of CO2 equivalent are released globally - means that it now poses a more significant threat to the atmosphere. (N2O emissions are calculated in terms of their impact on global warming, and CO2 is used...
...population" has lost some important connections, especially the tradition of sitting around the family album sharing cherished memories. These e-mail services help fill in those gaps. Bellanca, for example, feeds her father's passion for photography by Sunnygramming him several pictures with notes each week. My husband's Gram, who has seven kids, 15 grandchildren and four great-grandchildren, complains that she receives so many photos her Presto ink runs out too quickly.
