...Caltech's Chemist Linus Pauling, who won a Nobel Prize for his work on molecular structure, reported that the DNA molecule has a helical (spiral-staircase) structure. Later that year, James D. Watson and Francis H.C. Crick in England went a step farther. DNA, they said, is a double helix with two spirally rising chains of linked atomic groups and a series of horizontal members, like steps, connecting the two spirals. This molecular model, deduced mostly from X-ray diffraction photos, seemed complex and unlikely, but geneticists rejoiced when they heard about it. It was just what they" needed...
...charm of this structure for geneticists comes from its variability. Each step between the helices can be made of either pair of bases pointing in either direction. If the spirals should be pulled apart (the chemical bonds between bases are weak), each spiral would be left with the four bases arranged in any sequence. If arranged meaningfully along the spiral, the bases could carry information in a four-symbol code, much like digits on the magnetic tape of an electronic computer...
...unemployment was about as high, prices declined only .5%. In short, prices are growing more and more rigid. Unemployment stands at 7.5% of the labor force, yet prices are still climbing. Last month they hit an alltime record 123.5 on the index, and no real end to the upward spiral is in sight...
...installation of his sculptures, used in a ballet set in Gian Carlo Menotti's Festival of Two Worlds. Soon to be installed at the new Paris headquarters of UNESCO is the most ambitious of all Sculptor Calder's works -a 30-ft.-high mobile, The Clockwise Spiral...
...recession can be traced very largely to a revolt of the FIGs (Fixed Income Groups) against the wage-price spiral. If this spiral is not stopped, the FIGs will, in the end, be starved out of existence...
