...where thousands of individual samples of genetic material sit in tiny wells etched into plastic plates, each one identified by a unique bar code. One by one, Zeus searches for a particular code, dips into the corresponding well with a fine, quill-like probe and picks up a minuscule droplet of liquid...
Then Zeus transfers each precious droplet to a nearby sheet of nylon, moistens a designated spot and pivots back to the glass plates to find the next sample on its list. When Zeus is done, the nylon sheet will be spotted with a grid of about 1,000 droplets, forming what researchers call a microarray. Once the machine has created a few dozen of these arrays, they will be rolled up, inserted into glass tubes and doused with radioactive dye and genetic material from a range of human tissue types--from normal, healthy cells to diseased cells representing breast, prostate...
Invasions of settlers can help make conditions even dryer. Land burned and cleared by farmers releases less water to the skies than forest does. Moreover, smoke inhibits rainfall by saturating the air with vast numbers of tiny particles, each of which can become the center of a water droplet. But the droplets remain tiny, and do not become heavy enough to fall to the ground, according to a study conducted by David Rosenfeld at Jerusalem University in Israel...
...fire reduce moisture and rainfall and further enhance the prospects of more burning. Cleared land releases less water to the skies than forest does, while smoke inhibits rainfall by saturating the air with vast numbers of tiny particles, each of which can become the basis of a water droplet. But the droplets remain tiny, and do not become heavy enough to fall to the ground, according to a study by David Rosenfeld at Israel?s Jerusalem University. Instead, they stay in the sky, in effect as sterile clouds. This enhances the prospects of more fire, more smoke and even less...
...Iraq shipped toxins out by diplomatic pouch and handed them over to some cooperative terrorists, it might not be impossible. Iraq has also been tinkering with other methods. Before the Gulf War it had several hundred Italian-made pesticide dispensers fitted with spray nozzles for spitting out bioweapons in droplet size. In 1990 the Iraqis flight-tested a remote-controlled MiG-21 fighter mounted with a 2,200-liter belly tank and sprayer...
