There's no war going on between the U.S. and Pakistan yet, but recent exchanges involving American and Pakistani forces along the Pakistan-Afghanistan frontier are sounding like a sputtering fuse that's growing ever shorter. The latest series of "pops" occurred Thursday, when Pakistani forces fired on a pair of U.S. OH-58 scout helicopters buzzing along the border, and U.S. and Pakistani ground troops then exchanged fire. Pakistani officials insisted the choppers had crossed into their airspace, but U.S. officials said the incident occurred more than a mile inside Afghanistan - and the mountainous region is so poorly mapped...
Anyone who has struggled to change a fuse in their home should pity the scientists at the CERN laboratory in Geneva. Last Friday, just nine days after celebrating the successful test run of the largest particle accelerator ever constructed, a tiny electrical connection between two magnets overheated and caused a minor meltdown...
Another strategy, which is still experimental, unfortunately works best in male athletes. MRI of the wrist bones and the extent to which they have fused has been used to screen out boys too young to play football. The older the player, the more fused the bones should be. These structures, however, don't fuse the same way in girls, making this test gender-specific...
Other bones can provide additional clues. Elbow bones tend to fuse in a chronological order, so scans revealing how far along this process has come could provide more information about age. The skull can also be helpful. Babies are born with an unfused cranium and, as children grow up, a series of sutures come together to seal the gap. In some, however, certain sutures remain open through adulthood, making this an important but hardly conclusive test...
...plan backed by the panel calls for putting up to four non-explosive "dispersible kinetic energy projectiles" atop each missile. Each GPS-guided projectile would contain about 1,000 tungsten rods that would strike the target at a mile a second (a fuse could spew them more widely across the ground, with less impact, or let all 250 pounds hit the same point for maximum destruction). The force of a single rod, the report says, would be similar to that of a hefty 50-caliber bullet. The lack of any explosive would generate precise mayhem, "comparable to the type...
