...race rests flush against a hinged metal plate that drops forward into the asphalt at the start, allowing the vehicle to roll forward down the inclined raceway. As he settled back into his racer, Gronen's helmet touched off a lever that activated the battery and magnet, and as the metal plate fell forward the magnet's pull toward it gave his vehicle enough extra starting impetus to win. If that weren't enough, it turns out that Gronen's cousin, Robert Lange Jr., won the Derby last year, and both boys live in the same...
...from the emerging technology of cryogenics (application of temperatures close to absolute zero*) and helped to adapt an extremely cold probe to destroy hard-to-reach pituitary tissue in brain operations. Now Rand is making use of another recently utilized phenomenon: superconductivity. With the help of a powerful "superconductive" magnet, he is accomplishing knifeless, bloodless destruction of tumors...
Rand had previously employed magnetism in the operating room. In 1966, he injected microscopic iron spheres into blood vessels of patients who had suffered aneurysms, or "blowouts" in blood vessels in the brain. He used the magnet to hold the filings in place at the site of the rupture until new tissue grew over them to close the hole...
Rand's plan for destroying tumors required an even more powerful magnetic field. To get it, he used an electromagnet cooled by liquid helium to near absolute zero. That produced superconductivity: the virtual disappearance of electrical resistance in the magnet. This allowed a greatly increased flow of current and boosted the strength of the magnet to 3½ times that of the best alternate magnet available...
...nourishment or pass off wastes. To starve a tumor in one of his patients, Rand injected liquid silicone containing microscopic iron spheres into a blood vessel near the tumor. He waited until the material was carried through capillaries and into the tumor itself, then switched on his strategically placed magnet, which attracted the iron pellets and fixed them in the tumor. The spheres confined the viscous, quick-setting silicone, preventing it from entering the main bloodstream, where it could cause obstructions. The solidified silicone will remain in the patient for the rest of his life. But the tumor, its blood...
