Handle With Care
By CORNELIA DEAN, The New York Times, August 12, 2008
Last year, a private company proposed “fertilizing” parts of the ocean with iron, in hopes of encouraging carbon-absorbing blooms of plankton. Meanwhile, researchers elsewhere are talking about injecting chemicals into the atmosphere, launching sun-reflecting mirrors into stationary orbit above the earth or taking other steps to reset the thermostat of a warming planet.
This technology might be useful, even life-saving. But it would inevitably produce environmental effects impossible to predict and impossible to undo. So a growing number of experts say it is time for broad discussion of how and by whom it should be used, or if it should be tried at all.

Surpassing Nature, Scientists Bend Light Backward
By KENNETH CHANG, The New York Times, August 12, 2008
Using tiny wires and fishnet structures, researchers at the University of California, Berkeley, have found new ways to bend light backward, something that never occurs in nature.

Prescriptions for Health, the Environmental Kind
By AMANDA SCHAFFER, The New York Times, August 12, 2008
In a bright studio at New York University, Natalie Jeremijenko welcomes visitors to her environmental health clinic. She wears a white lab coat with a rotated red cross on the pocket. A clipboard with intake forms hangs by the door.
Inside, circuit boards, respirators, light bulbs, bike helmets and books on green design clutter the high shelves. In front of a bamboo consultation desk sits a mock medicine cabinet, which turns out to be filled with power tools.
Dr. Jeremijenko, an Australian artist, designer and engineer, invites members of the public to the clinic to discuss personal environmental concerns like air and water quality. Sitting at the consultation desk, she also offers them concrete remedies or “prescriptions” for change, much as a medical clinic might offer prescriptions for drugs.

Science Visuals: How the First Farmers Colonized the Mediterranean
By NICHOLAS WADE, The New York Times, August 11, 2008
The invention of agriculture was a pivotal event in human history, but archaeologists studying its origins may have made a simple error in dating the domestication of animals like sheep and goats. The signal of the process, they believed, was the first appearance in the archaeological record of smaller boned animals. But in fact this reflects just a switch to culling females, which are smaller than males, concludes Melinda Zeder, an archaeologist at the Smithsonian Institution.
