...first time in the history of science or agriculture, man may be about to make a fundamental improvement in the unique power of plants to manufacture food out of carbon dioxide and water in the presence of light. Selective breeding, long practised to increase the yield of plants, may eventually be looked back on as little better than superficial when compared with a new method described last week by Cornell's Botanist Lewis Knudson. Using X-rays, Knudson has permanently increased the size of plants' cnloroplasts-the cell's tiny granular bodies where chlorophyll makes sugar...
Shotwelding is a refinement of spot welding designed for stainless steel (usual formula: 18% chromium, 8% nickel), whose great tensile strength-four times that of ordinary carbon steel-is lost when it is heated to 1,100° to 1,600°. The Shotwelding electrodes stab the metal for 1/10 th 1/20 th of a second, heating it so instantaneously through its danger zone to its 2,700° fusing point that the alloy's unique strength is not affected. Invented by Budd Manufacturing Co. (and used for making stainless steel railroad coaches), Shotwelding may well make steel planes...

...being tried in the West on two other very common ores, brucite (Mg(OH)2) and magnesite (MgCO3). When either of these is baked it forms magnesium oxide, and the trick is first to vaporize this by heating it to 3,800° F. in the presence of carbon and then cool it to around 380° in 1/1000th of a second with a blast of cold gas. During the heating, the carbon takes the oxygen away from the magnesium, and during the cooling the magnesium is precipitated as a fine powder too fast to recombine with the oxygen. This...
...carbon monoxide gas brought quiet to the child. From time to time the parents went into the room to look at their son. Finally the mother took it from the crib, walked up and down a few times, hugging and kissing the child. It was dead...
