...planner at the Pentagon preparing for war--figuring how to move a flotilla of cargo vessels from San Francisco to the Persian Gulf, worrying whether there's enough shrink-wrap at the port in Jacksonville, Fla., to protect the AH-64 Apache gunships and Black Hawk and Chinook helicopters you've just started to fly there from Fort Campbell, Ky.--there's one thing you always want to keep in the back of your mind. And that is the state of the night sky. The U.S. Air Force likes to begin its bombing campaigns on moonless nights, and in Iraq...
Each day now, as we discover where we are vulnerable, we move closer to designing drugs to protect us. Gene therapy allows doctors to introduce some handy gene into the body like a little rescue squad, to help produce enzymes that because of some faulty gene, the body can't make on its own. When we finally find cures for cancers, they will reflect the secrets of how our genes fight some cancers and yield to others. Drugs like Herceptin for breast cancer and Gleevec for leukemia work by blocking the chemical signal that tells the cancer to grow. They...
...most notorious piece of evidence was the bit of hardened foam that fell from the external fuel tank during lift-off, striking Columbia's left wing area. Applied like shaving cream, the foam dries to the hardness of a brick, which could conceivably damage the fragile external tiles that protect the shuttle during its fiery re-entry. When it was later disclosed that the spacecraft had spent 39 days idling on the pad before launch--enduring episodes of freezing rain that could have loosened the foam further--the case seemed closed...
...exactly what it says. Instead of clearing the forest, farmers plant the crop among the forest plants, thus saving the local ecosystem. Shade trees furnish habitats for birds, and the Atlanta Audubon Society has found that 90% fewer species are found in sun-grown coffee areas. Shade trees also protect coffee plants from harsh elements, and the birds that are attracted provide natural pest control, which reduces the need for synthetic pesticides. As a bonus, many coffee drinkers find shade-grown varieties less bitter than those grown...
...mammals have been flown from their home base in San Diego to Bahrain to see whether they can help protect U.S. ships against Iraqi frogmen and mines. Living in pens on land next to the Persian Gulf, the sea lions, which average around 350 lbs. each, will hop aboard boats and dive into the water near the ships they are protecting. Their keen eyes and hearing allow them to detect intruders or mines far better than their human counterparts. A sea lion can swim up to 25 m.p.h. for short bursts, enabling it to nab an underwater foe by snaring...
