    In this article, Alan R. Templeton of Washington University used 10 sources of DNA for his geographic study of human origins. Peter A. Underhill of Stanford feels the population sampled was too small for statistical significance. How many would it take for an expanded version to be significant? Is there a chance such an enlarged […]

    DNA Diaspora: Humanity may share tangled genetic roots

    A controversial new genetic analysis concludes that Homo sapiens evolved by expanding out of Africa in multiple waves beginning at least 600,000 years ago and then interbreeding, rather than totally replacing close relatives such as the Neandertals.

    Space Rocks’ Demo Job: Asteroids, not comets, pummeled early Earth

    An analysis of trace elements found in a variety of meteorites suggests that most of the heavenly objects that rained hell on the inner solar system about 3.9 billion years ago were asteroids, not comets.

    In your coverage of the recent sonofusion work, you make the unsubstantiated and false remark regarding cold fusion and Martin Fleischmann and Stanley Pons: “However, neither the original pair nor anyone else could reproduce those findings, which have largely been discredited as a case study in mistaken science.” The peer-reviewed literature since 1989 does indeed […]

    Star in a Jar? Hints of nuclear fusion found—maybe

    In a bench-top experiment, atomic nuclei may have fused inside rapidly imploding bubbles of vapor in a liquid bombarded by sound waves, but many scientists find the evidence for bubble fusion unconvincing.
