...greenhouse-gas emissions, global temperatures will rise between 1.1?C and 6.4?C by 2100. If carbon levels double from the pre-industrial norm-something many experts say is a lock-the IPCC believes the mercury will rise by about 3?C, accompanied by longer and more intense heat waves...
...Edwards's strategy is working for him so far. Obama was once the hero of the liberal blog world, but a poll of more than 20,000 readers on Daily Kos this week showed Edwards and he in a virtual dead-heat, with Edwards leading 26% to 25%. (As Dean learned, wooing the Netroots is complicated; Edwards is also in a controversy over some bloggers he hired.) The crowd at the Democratic National Committee winter meetings clapped continuously during Edwards's speech there, as he repeated his calls for his party to show "courage" in opposing the war. Labor leaders...
...Joint Chiefs, told a Senate panel Tuesday before the latest loss. Unfortunately, there is no shortage of AK-47s in greater Baghdad. Other Pentagon officials wonder if the insurgents have gotten hold of a fresh batch of SA-7 Grail shoulder-fired anti-aircraft missiles. While a primitive heat-seeker, its range of more than three miles is bound to find its target occasionally. Pace didn't have a quick solution...
...chemical properties that make it an ideal workhorse material for everything from semiconductors to biosensors. "To my mind, it's a case of finding what diamond enables that nothing else can do," says Donald Sadoway, a professor of materials science at Massachusetts Institute of Technology. Because it conducts heat so well, for example, diamond could be particularly useful for the small-electronics industry, which relies on ever more powerful processors that generate incredible amounts of heat. (Just try working with your laptop computer actually on your lap for a few hours.) "When you go to the next-generation semiconductor...
...easy feat. Rather than trying to mimic the conditions under which diamond is generated deep in the earth, Apollo, Element Six and most of the other leading diamondmakers are relying on a process called chemical vapor deposition (CVD). It's a low-pressure, high-temperature method that uses heat energy from plasma and a combination of gases to rain carbon atoms on a starter seed of the gem, which gradually grows into a larger single-crystal diamond. CVD produces a more uniform, consistent diamond in sizes large enough to make an effective transistor. Using the diamond it created...
