...inheritance by puttering with peas. He showed, for example, that if a "dominant" yellow pea is bred to a "recessive" green pea, all the first generation peas will be yellow, and three out of four of the second (if bred together) will be yellow and one green. This ratio always holds in breeding a dominant to a recessive. At the dawn of the 20th Century, Mendel's laws were dug up and made the basis of the science of genetics, which was also boosted through experiments on fruit flies by Thomas Hunt Morgan, now a venerable Nobel Prizeman...
...Permit the States to reduce their unemployment insurance contributions, if their reserve funds are at a safe ratio to their minimum annual outlays. In the 39 States whose reserves are in a condition permitting reductions, employers stand to save $200,000,000 to $250,000,000 in 1940. > Limit the annual income taxable for unemployment compensation to $3,000, which is now the maximum taxable for old-age insurance.

...external galaxies, when broken up into its component colors by a prism or grating, is shifted toward the red end of the spectrum, indicating that the galaxies are retreating in all directions.* For them, the apparent velocity is roughly proportional to the distance. But among the nearest galaxies, this ratio does not hold. The Milky Way appears to be approaching some, receding from others. To isolate this motion, Dr. Hubble had to allow for and discount the sun's own movement within the Milky Way-since he was perforce using the solar system as an observation station. After...
...infantry rate 100, Colonel Love arrived at the following index of losses for other services: machine gunners (now in the infantry) 70.12; signal corps 16.46; tank corps 15.85; artillery 11.58; engineers 9.15; medical 8.54; cavalry and quartermaster department 3.05 each; aviation and ordnance 1.83. In the World War the ratio of losses for every 1,000 infantrymen in combat was as high as 349.6 killed & wounded in one day of intense attack, more often was no to 150. Guessing for the next war, the U. S. Medical Corps expects 150 daily casualties (24 killed, 96 shot & wounded, 30 gassed...
...clear that the continued European crisis was. Markets were nervous. Businessmen cut their buying for the future so low that three new indexes of inventories published by the National Industrial Conference Board touched the lowest point since May 1937. Most cheerful fact of the week (to businessmen): the sales ratio of twin beds to double beds was up from...
