...Parity Killers. Two young Chinese living in the U.S., Drs. Chen Ning Yang and Tsung Dao Lee, split the Nobel physics prize for destroying the principle of "Conservation of Parity," on which a good deal of modern physics had been based. The principle says that objects which are mirror images of each other must obey the same physical rules. As Drs. Yang and Lee dug deep into the mysteries of the matter, they felt that they could not do without parity, but they found several basic things that could not be explained if parity were observed with full reverence...
...Okapa, Drs. Gajdusek and Zigas ran the risk of getting kuru themselves (if it should prove infectious); lacking surgical gloves, they did autopsies barehanded. They performed them on a dining-room table in the patrol officer's quarters, often eating a meal at one end while discussing the kuru-damaged brains lying at the other. They shipped specimens to Melbourne and to the U.S. National Institutes of Health at Bethesda, Md. From 154 patients and their kin, they got a detailed picture of kuru's course, though no clue to its cause...
...semiburied implant, using a Vitallium latticework placed on the mandible, or lower jaw. As the process is described in Implant Dentures (Lippincott; $12) by Drs. Aaron Gershkoff and Norman I. Goldberg of Tufts University School of Dental Medicine, soft tissues are sutured over the lattice, leaving four posts protruding in the mouth to support and anchor dentures...
...There is strong evidence that a link may exist between leukemia and Mongolism. two Minneapolis researchers report. Drs. William Krivit and Robert A. Good of the University of Minnesota found that in four years (1952-55) the two conditions occurred together at least 34 times in children four years old and younger, far oftener than the number (12.3) expected from chance alone. Likelihood that the cases occurred by chance in a four-year span, say the statisticians. is less than one in a thousand. If existence of a link between the two presumably incurable conditions is proved, important clues...
Trap at Night. At Cornell University Medical College, Drs. Mary H. Loveless and William R. Fackler have worked out a painstaking method of trapping bees and wasps by chloroforming them in the nests at night, storing them in a freezer, and performing delicate surgery to remove their venom sacs while they are in a half-frozen stupor. The venom from the sacs is pooled, then injected in small but gradually increasing doses into sensitive subjects. In the New York City area, the doctors found, the most vicious stinger by far is the yellow jacket (Vespula maculifrons, represented elsewhere...
