...Eating, for example, is possible in part because the + immune system does not mount an attack on something that has passed through the gut. So Harvard's Weiner has begun feeding small doses of myelin to some multiple sclerosis patients in the hopes of increasing their tolerance for the protein. Scientists are also supplementing the diets of people who suffer from rheumatoid arthritis with tiny doses of specially prepared collagen...
...scientist was record exactly what you observed (in ink, in notebooks that never left the lab). The most you could do was arrange the experimental circumstances so as to entrap the elusive It and squeeze out some small confession: This is how the enzyme works, or the protein folds, or the gene makes known its message. But always, and no matter what, you let It do the talking. And when It spoke, which wasn't often, your reward, as one of my professors used to say, was "to wake up screaming in the night" -- at the cunning of Its logic...

Some experts contend that all older men should be tested. Predicts lead author Dr. William Catalona, at Washington University in St. Louis: "PSA should dramatically alter the statistics on prostate cancer...
...basis for the new assay, PSA, is a protein produced by cells on the surface of the prostate and thought to play a role in preventing semen from coagulating. An enlarged prostate (due to cancer or other problems) leads to higher levels of PSA in the blood. Doctors already use PSA tests to monitor the effectiveness of prostate-cancer therapies, such as irradiation or hormonal treatments. Some researchers have argued that the exams should replace much more expensive bone scans as a way of determining how far the cancer has spread...
...meat is dark, tasty and similar to beef but has one-eighth the fat and 15% less cholesterol, with just as much protein. Ostrich meat is lower in calories than even chicken and turkey. America's 1,000 or so ostrich growers, who raise the birds for their hides and feathers, are thrilled by the potential of this new market. Says ostrich rancher Gary Teixeria, who had the burger brainstorm and passed it on to Barredo: "The public is just eating...
