...rats, for example, we know that the male retina has more cells designed to detect motion. In females, the retina has more cells built to gather information on color and texture. If the same is true in humans, as Sax suspects, that may explain why, in an experiment in England four years ago, newborn boys were much more likely than girls to stare at a mobile turning above their cribs. It may also help explain why boys prefer to play with moving toys like trucks while girls favor richly textured dolls and tend to draw with a wider range...
...late 1998, when the first of the COX-2 inhibitors won FDA approval, the stage was set for a debacle. The easiest side effects to detect, once a drug is used by large numbers of people, turn out to be the rare ones. Most doctors don't see very many cases of liver failure, for example. So they notice right away if more and more of their patients get hospitalized for it. The problem with COX-2 inhibitors like Vioxx is that they increase the risk of two very common ailments: heart attacks and strokes. It's much harder...
...Seeing Red A Danish biotech company has developed a new way to detect land mines using genetically modified THALE CRESS, a member of the mustard family. The plant turns a deep red when exposed to nitrogen dioxide, a gas released by mines. The grow-anywhere green, which scientists propose to sow from airplanes or handheld seed-shooters in heavily mined areas, could prove an inexpensive and safe solution for land mine detection?a boon to countries like Cambodia, which harbors an estimated four million mines...
...officer was sent to Lowell House to investigate the scent of gas. The officer determined there was no such odor but did detect the scent of something recently painted...
...could not have evolved bit by bit because a bit of an eye has no survival value; it would never have been passed on. Biologists see it differently. They say, for example, a primitive, light-sensing patch of skin--a forerunner of the retina--could help animals detect the shadows of predators...
