...They explored the cold depths with drills and with shock waves from explosions. They took samples of wood from ancient trees left behind like exhumed corpses by the huge Mendenhall glacier, in the southeastern part of the field. When the ages of these trees have been measured by the carbon 14 method (see below), the glaciologists may know what the glacier was doing thousands of years...
While the infant lotuses flourished in their Washington greenhouse, another batch of the seeds was sent to Dr. Willard F. Libby of the University of Chicago. Libby decided to check their age by measuring their content of radioactive carbon 14.-In the current issue of Science Dr. Libby reported his findings: his tests on 19 of the lotus seeds had proved that they are 1,000 years old, give or take a couple of centuries. This is nothing like 50,000 years, but it makes the seeds the oldest of any species that have yet been known to sprout after...
...house its radar, periscope and snorkel (which is a convenience, not a necessity, on an atomic submarine). Inside, the SSN will open up an entirely new world to sailormen accustomed to the smelly, cramped interiors of standard subs. It will have its own oxygen supply and a special carbon dioxide removing room to freshen the air its crew breathes. There will be vast space for the complex array of dials and electronic gadgets, huge torpedo rooms to hold a school of homing torpedos. The familiar throbbing diesel engines will be gone. Instead, a single atom-powered steam turbine will drive...
...pressagents searched high & low for the kind of face that would look appealing in the glow of a blast furnace, picked Traude. Forthwith she became a "model" furnace worker, was billed as the "first woman rolling-mill engineer," and began wrestling with white-hot sheet metal instead of carbon copies. Her smudged but happily smiling face graced the front pages of Germany's Red press, and a Communist movie company made a picture about...
...promising is another aspect of the Syntex accomplishment. The steroid hormones are, in effect, "code words" which help to control the cells of the body. They are all very similar, built around the same nucleus, but the slightest difference (such as the shift of an oxygen atom from one carbon atom to another) changes their effect. Medical researchers would like to try hundreds of steroids to see what each can do to make the body work properly...
