DECEMBER 1955
SPACE BIRD--"Some time in the next few years a new object will appear in the heavens. It will be quite inconspicuous. But as men lift their heads and, watching, catch a glimpse of this faint body racing across the sky, they will feel the excitement of witnessing a great historic event. For the tiny object circling the heavens will be metal that man has touched, a satellite that man has made and flung from the earth into space. The satellites that the U.S. will launch for the International Geophysical Year (1957-1958) are still, of course, only scribbles and sketches on pieces of paper."

THERAPY OR POISON?--"In 1940 a Boston ophthalmologist was abruptly confronted with a new disease which defied his skill to diagnose, let alone to treat. In the course of just a few months he examined six cases of babies going blind from some obscure cause. By July 1950, statistics seemed to show that the babies who developed retrolental fibroplasia had been treated for oxygen deficiency, as evidenced by the fact that they were kept under oxygen longer. It had not yet sunk in that the giving of oxygen might itself be the cause of the trouble. Retrolental fibroplasia emerged in epidemic proportions when hospitals began to expose premature babies to very high oxygen atmosphere in efficient new incubators. Often the atmosphere used was 50 percent oxygen."

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
