After Pearl Harbor, Dec. 7, 1941, the first few months of World War II were
grim. The U.S. Pacific fleet was crippled, and the United States lost dozens
more warships in a series of naval setbacks. The Japanese took Guam and
overan the Phillippines, though Gen. Douglas MacArthur promised to return. It
would be three long years before MacArthur would in fact return in October of
1944, wading ashore at Leyte as a prelude to liberating the Phillipines.
In mid-1942, some 500 magazines, including Popular Science, joined together
There are nearly 2,400 surveillance cameras visible from the street in
Manhattan alone, according to a recent count by the New York Civil Liberties
Union Surveillance Camera Project-many of these installed by corporations.
The Website i-SEE shows where all of these cameras are and generates maps of "the safest path of least surveillance."

First, Meet Mark, a graphic designer in Chicago. Like most of us, Mark knows his boss can read his e-mail, insurers can access his medical data. but he's blind to the bigger truth: personal data is collected, and sometimes shared, at a fantastic rate.

The shorter your kayak, the smoother your ride. Dagger's new UFO, at slightly less than 6 feet long, is the shortest you can buy. Its hourglass deck scoops up and unloads water, lifting the boat and putting big-air moves like end-over-end flips into the repertoire of rookies. Plus, at an unheard-of 25 pounds, it's easy to transport. Available in August for $1,175.

The 10-pound prototype Cryo3 is the first handheld radiation detector, not only allowing security personnel to quickly check for radiation anywhere but also to determine the exact amount and type. Gamma and X rays emitted from so-called dirty bombs interact with a high-purity geranium crystal at the unit's core to create a unique charge, which is analyzed by a computer to determine the radioactive isotope. The device, a joint effort of Lawrence Berkeley, Los Alamos, and Lawrence Livermore national labs, could be in use as early as next year.
Alcohol-related accidents kill 16,000 Americans a year, but drugs like cocaine, marijuana, angel dust, and amphetamines also take their toll. Enter Impact, which examines saliva for as many as 10 drugs in less than 5 minutes. Inside the device, saliva mixes with fluorescent chemicals that bind to drug or alcohol molecules. If either is in your system, the computer picks up the fluorescence.
If Mark Allen could find a way to pour beer with a consistently frothy head, the part-time barman figured he could work faster and get better tips. His prototype dispenser holds the glass at a 45-degree angle. As beer flows, the glass slowly moves to an upright position. The rate of incline depends on beer type-stout, lager, or bitter. The result: a perfect head, every time.
4 Steps to the Perfect Cold One at Home
You don't need a high-tech dispenser-Mark Allen offers these tips:
Since the collapse of the Soviet Union, the world landscape of trust and stability has dramatically changed. Instead of a Cold War or threat of confrontation between two superpowers, countries around the world have had to brace for the possibility of deadly attacks from terrorists that could result in a scenario, such as the World Trade Center tragedy. Renowned author Tom Clancy visits such an attack in his New York Times bestseller The Sum of All Fears.
There's equipment to reduce landmine risk, but the technology is imperfect.

In afghanistan, where landmines kill or injure some six people each day, soldiers in very strange-looking boots are often seen prowling about minefields. At first blush it seems naive to even ask the question-can the right footwear offer significant protection?
