Sluggish sales aside, GM is recovering much of its investment by using the EV1, which alone spawned 23 patents, as a rolling research lab. The car has one-third less aerodynamic drag than any other car on the road. Features such as magnesium frame seats and highly inflated lightweight tires are being adopted in conventional GM cars. "The payback is not going to come through sales of EV1s in the short run," says marketing director Kennedy. "GM is laying the foundation for leadership on advanced-technology vehicles 10 or 20 years from now. That surprises people. They don't expect...
...seek help. H2 blockers still have fewer side effects than antacids. (Tagamet may interfere with the body's ability to metabolize certain drugs, but the incidence, say researchers, is not significant.) Meanwhile, calcium-based antacids like Tums and Rolaids can occasionally contribute to kidney stones, and aluminum- and magnesium-based ones like Mylanta and Maalox can sometimes be dangerous for people with kidney problems. Says clinician Dr. Thomas Gage, a member of the A.G.A.'s patient-care committee: "The risk-benefit profile for H2 blockers is excellent, and they represent an advance over what was previously available...
...chemistry of the vents has provided answers to questions that have perplexed scientists for years. For example, marine geochemists could never understand why the amount of magnesium in seawater remained relatively constant, even though the element is continually eroding into the oceans from dry land. Now they know that magnesium is completely stripped from seawater as it passes through the hot rock--something all the water in the oceans will do every 10 million years...
...study of 2,300 patients showed that giving a shot of magnesium sulfate within three hours of a heart attack may prolong a person's life by a few years. The timing is critical, however, as there was no beneficial effect in those cases where doctors waited eight hours or more to administer the drug...
...Three drugs given to heart-attack victims -- magnesium, nitrates and captopril (the drug just found to be good for diabetics' kidneys) -- are surprisingly ineffective. Still worth taking: aspirin, clot dissolvers and beta blockers...
