    As a malacologist, I enjoyed this article. Although the holes look like what could be made with a stone tool, the Science paper acknowledged that a small percentage of naturally occurring holes look similar. Either the people deliberately selected shells with suitable holes or else they perforated them deliberately. Both options show effort at obtaining […]

    When discussing how polarized light can help clarify our understanding of supernova mechanisms, this article initially quotes Doug Leonard’s explanation that “one does not see deeper into an object using polarimetry.” Later, the story says that “polarization studies viewed deeper and deeper layers of the explosion.” Which is it? Hal HeatonDamascus, Md. Polarization studies don’t […]

    If the estrogenic properties of lavender oil and tea tree oil are actually sufficient to produce these effects in young boys, could they produce potentially more serious negative impacts on women with estrogen-positive breast cancer?

    The photo in this article looks to me more like a solar eclipse, complete with a clear-cut circular blackout in the center and flares. Mike PattersonGrand Rapids, Mich. The similarity is because astronomers used an occulting disk on the telescope to block the glare of the central star .—R. Cowen

    This article makes two questionable assertions. First, Tyrannosaurus rex might well have had excellent binocular vision and been a predator, but still have had a handicap for the detection of motion as my cats do. Second, when Thomas R. Holtz Jr. states that binocular vision “almost certainly was a predatory adaptation,” that puts us binocular […]

    If having biological older brothers correlates to homosexuality, as claimed in your article, then we would expect that in the past, when families were larger, there would be a greater proportion of homosexuals. Is there any evidence for this? Rick NorwoodMountain Home, Tenn. The article concludes with psychologist Daryl Bem inferring that male homosexuals are […]

    Please check the picture in this article. The teeth shown are lower teeth. Theodore BlinderHavertown, Pa. The story and caption misidentified the teeth that had been filed down 4,300 years ago. They were the bottom-front teeth, shown at left in the photo. —B. Bower

PyeOak Hills, Calif . Limited evidence suggests that vitamin B12 absorption may be impaired in some people with chronic fatigue syndrome. No published […]

With some tweaking, could nearsightedness and astigmatism be treated as well? Could binoculars, telescopes, and microscopes use this technology? Roger CurnowGrand Rapids, Mich. Yes and yes, says […]
