...most important feature of the new furnace is that contamination of the metal under study, by carbon or other impurities, can be entirely eliminated. The familiar carbon are reaches as high temperatures as the electron furnace; but as an experimental device the carbon arc is less effective because of uncontrollable carbon contamination...

Died. Rosamond Pinchot Gaston, 32, tall, handsome actress (the nun in Max Reinhardt's Miracle, 1924), niece of Pennsylvania's onetime Governor Gifford Pinchot; of carbon monoxide poisoning; in a garage at her Old Brookville, L. I. home...

This is photosynthesis, the manner in which green plants create organic food substance from carbon dioxide and water, in the presence of sunlight and chlorophyll. Chlorophyll, which does not take part in the transformation, is nevertheless the catalyst or activating force which makes it possible. All animals, including man, get their sustenance directly or indirectly from the energy stored by green plants. Thus if it were not for the chemical reaction summarized in the above equation, no life on earth could exist...

...catalyst is no longer effective. Scores of laboratories working on the problem of imitating natural photosynthesis have tried other catalysts, but none works so efficiently as chlorophyll. Some ten years ago at the University of Liverpool, Professor Edward Charles Cyril Baly obtained formaldehyde, sugar and starch from carbon dioxide, water and artificial white light, using nickel oxide as a catalyst, but in tiny quantities and at low efficiencies...

There is no practical reason now for harnessing the sun's energy. But should the problem become urgent, because of depletion of the earth's supply of coal and oil, it would be possible to use huge shallow tanks of water and carbon dioxide for solar power plants if a catalyst as good as or better than chlorophyll could be found. Meanwhile Dr. Baly is considered in many quarters to be the world's leader in artificial photosynthesis of organic substances...
