Science: Shhh, Scientists at Work

> Atom-smashing research has now become secret at the University of California-including further developments of the half-built 4,900-ton cyclotron.

> “Voluntary censorship” of all U.S. scientific publications was announced by the National Academy of Sciences and the National Research Council. Reason: lest research data of indirect military significance fall under enemy eyes.

> There is so little new, nonsecret research that The Physical Review, abstruse physicists’ tradesheet, now appears only once a month instead of twice a month; and other once-plump learned journals are beginning to show their ribs.
