...Carbon dating has been recalibrated in recent decades to give archaeologists strong certainties about the ages of key artifacts for Europe's prehistory, from the drawings in France's Chauvet Cave (32,000 years old), to possibly Neanderthal milk teeth found in Cavallo, Italy (31,000 years old), to the Minoan civilization on Crete (3,700 years old). That means there is always the prospect of a physical discovery - an agricultural site that doesn't fit in time or space, say - that can blow existing theories out of the water...
Calkins is one of 5,000 Americans who have shelled out $2,750 for a special edition Sony Aibo robot dog, which makes you understand a little better why he ends his e-mails with the tag line: "Silicon shall replace carbon. The revolution will be automated." When he was a kid, Calkins owned a German shepherd, but that was before he discovered computers. Now he works at an Internet firm, dotes on his pet robot and in his spare time serves as president of the Robotics Society of America...
...George W. Bush's chief strategist, Karl Rove is supposed to keep the President in a healthy political glow. But on one key issue recently, Rove stood by while Bush turned as gray as a hazy day in Houston.

Moderate Republicans were getting jittery. So last week Rove and other aides pulled out the green paints and brushes and set to work...
Your coverage of global warming and the White House's opposition to the 1997 Kyoto Protocol to cut carbon dioxide emissions was heartening [SPECIAL REPORT, April 9]. George W. Bush's decision is just the latest and perhaps the most serious in a string of setbacks on environmental issues that have come out of Washington. Bush and his colleagues should realize that without clean air and the right temperature to support life at all levels, a healthy economy won't be possible. Truly, our economic health depends on environmental health. JUDY MATA Hemet, Calif...
...best to come up with an all-inclusive list of 20 things you can do to reduce carbon dioxide output, but several of you came up with novel ideas we had overlooked. A Montana resident suggested ending NASCAR competitions, which consume thousands of gallons of fuel per race. A Maryland man proposed shunning large houses in favor of smaller, more energy-efficient homes--an idea a San Jacinto, Calif., homeowner put a slightly different spin on. "Many of us have small lawns that we mow with gas or electric machines," he wrote. "Why not switch to manual or push lawn...
