...think a girl could be left alone after 500 years, but if anything, the scrutiny of the Mona Lisa is more intense than ever. After studying the painting with 3-D laser scanners, researchers posited last week that Leonardo da Vinci's subject was pregnant, lending scientific cred to an old theory. "People have said there is an enigma to the Mona Lisa," says historian Donald Sassoon, author of Becoming Mona Lisa. "That makes it popular because people like enigmas and secret codes." True enough. Here are some puzzles scientists and writers think they've solved in just the past...
...Anderson said, tattoo ink has contained a number of potentially unsafe and non-sterile materials, and often causes allergies or other problems. Older types of inks are also much more difficult to remove. “The inks that are out there now need about four to twelve [laser] treatments to be removed,” says Anderson, who specializes in scarless laser tattoo removal. “Right now if you have a multicolored tattoo, you may need separate treatments to remove each color.” In contrast, the ink that Anderson and his colleagues have developed...

...guided munitions and laser-targeted bombs--sighted by satellite, spotter aircraft and unmanned vehicles--would do most of the bunker busting. But because many of the targets are hardened under several feet of reinforced concrete, most would have to be hit over and over to ensure that they were destroyed or sufficiently damaged. The U.S. would have to mount the usual aerial ballet, refueling tankers as well as search-and-rescue helicopters in case pilots were shot down by Iran's aging but possibly still effective air defenses. U.S. submarines and ships could launch cruise missiles as well, but their...
