Brookhaven is also studying the effect of radiation on plants. A field has been marked off with concentric circles, and various crops have been planted on the circular lines. In the center is a powerful source of radiation (cobalt 60). By the end of summer, Brookhaven's nuclear-agronomists will know more about radiation effects upon growing plants...
...year-old prospector named Ernest Johnson started it all. In two years of experience with radioactive ores around the Eldorado mine on Great Bear Lake, he had noticed that where there was uranium there were also cobalt and nickel. Figuring that the converse should be true, he packed a Geiger counter and pushed up the Roxey Creek valley, 120 miles north of Vancouver, where fallen rock bearing cobalt "bloom" lay in the creek...
Sample smash: an arsenic atom (atomic weight: 75) had 21 particles knocked off by a single blow, and was reduced to radioactive cobalt (atomic weight: 54). When the new cyclotron bombarded an oxygen atom (atomic weight: 16) with neutrons, the light atom split into five pieces (see cut; the arrows point to the five-way split of the oxygen atom, the streaks indicate the path of atomic chips...
...frustrated feeling last week over a bit of news that plodded, with maddening deliberation, out of Russia. According to V. O. Fesenkov, chairman of the Meteorite Committee of the U.S.S.R. Academy of Science, a ""minor planet" landed on eastern Siberia last Feb. 12.

With the new price of silver providing an added shot in the arm, Cobalt's prospects are rosy. Already five mines are back in production. A new $600,000 smelter will soon begin refining silver and cobalt on the spot. As newcomers drift in and new homes go up, some of the optimism of old-time Cobalt is being recaptured. Says a sign outside Michael Brosko's store: "Silver is back...
