...Snyder announced in print that his lab had removed stemlike cells from mouse brains and had grown them in a culture. Snyder then teamed up with Dr. Jeff Macklis, a colleague at Harvard Medical School who had engineered a strain of mouse whose neurons died off in a tiny region of the cortex where cells were not known to regenerate. Snyder injected the stem cells into the mice. Like heat-seeking missiles, the cells rapidly sought out the injured part of the cortex and transformed themselves into healthy neurons. "That's the beauty of stem cells," says Snyder...
...conventional wisdom says no, but by mid-century that assessment--along with the sniffles--may well be ancient history. Colds are considered incurable today because it would take months to come up with a vaccine for every new strain. That's fine for the flu, which breeds in animals and only jumps over to humans every year or two. But colds mutate even while they're infecting you, and new strains pop up so often that by the time drugmakers create a vaccine against one variation, the serum is already out of date...
...point the way toward a cold cure though. Scientists at the University of Ghent, in Belgium, have found a protein called M2 that seems to be present in virtually every flu strain known to man. Using that knowledge, they have made a vaccine that they think could protect against all flus--old, new and those not yet in existence...
...similar protein is found in cold viruses--a protein that's present no matter what strain is involved--then it is possible that by 2025 or so, children could be getting a universal cold vaccine. And then they will have to listen to us old geezers reminisce about the days when we used to carry a small white cloth called a handkerchief...
...Hattner, a clinical nutritionist at the UCSF Stanford University Medical Center who attended the conference, worries about the high levels of protein and fat in many of these diets, as well as their lack of fiber. "Removing fiber causes constipation, fluid dehydration, weakness and nausea. It's a great strain on the kidneys," she says. Keith Ayoob, a professor of nutrition at Albert Einstein College of Medicine in New York City, warns about other "very unpleasant side effects--sometimes really bad breath...
