...Hawaii discovery did not mark the first time a moonlet had been found around an asteroid. In 1993 the Galileo spacecraft sped past the 20-mile-wide asteroid Ida and spotted a scrap of moon just under a mile wide circling it. But the only way Galileo could detect the tiny target was to fly there across many millions of miles of space and do its exploring up close. Now, thanks to new optics in the CFHT, it's possible to search for moonlets from the comfortable perch of a faraway Earth...
Others worry that rogue nations would violate a test ban treaty, conducting surreptitious tests and building their arsenals while the world lay complacent. This argument is frivolous. The treaty calls for a global network of sensitive seismic monitoring stations that would detect any nuclear test large enough to be militarily useful. If, indeed, the Chinese government did steal secrets from our nation's nuclear laboratories, only a ban on testing could prevent those secrets from being put to use. Furthermore, any illicit testing that the treaty's enforcement provisions would miss could certainly occur (and undoubtedly would) if the treaty...
...Instead, they're just as apt to signal us with beams of light. Says physicist Freeman Dyson of the Institute for Advanced Study in Princeton, N.J.: "It's foolish to try to guess what an extraterrestrial civilization might use. You ought to try all available technologies to detect...
Scientific Learning's harshest critics charge that it hasn't done its homework. For example, many speech experts contend that reading difficulties arise from a failure of the brain to translate sounds into language, not from an inability to detect clear sounds, as Scientific Learning maintains. The company's own studies have "never been done with proper controls" to test its theories, argues psychologist Michael Studdert-Kennedy, chairman of Haskins Laboratories, a leading center for the study of speech and language at Yale University. Replies Paula Tallal, a neuroscientist at Rutgers University's Newark, N.J., campus and a co-founder...
