According to your article, exposure to the Epstein-Barr virus in early life produces only flu-like symptoms but exposure at adolescence or later often results in mononucleosis, which is a possible precursor of multiple sclerosis, diabetes, rheumatoid arthritis, and chronic fatigue syndrome. It seems to me that much human misery could be eliminated by developing a […]

Check it out In “Profiles in Melancholy, Resilience: Abused kids react to genetics, adult support” (SN: 11/20/04, p. 323), you report on a study in which it was found that female monkeys raised in a stressful situation drink alcohol to excess only if they possess just the short serotonin-transporter gene. If a positive correlation were […]

Plastic solar cells may indeed be gaining in efficiency, but here in the Southwest, anything plastic left out in the sun quickly clouds, desiccates, and cracks. Can the new polymer-based material protect against this destruction? It would certainly be cost prohibitive to replace the cells every year. Stephen WustSanta Fe, N.M. Researchers are well aware […]

Titan may represent conditions that existed on Earth when life arose. One important difference is the extremely cold temperature on Titan. However, the known life cycle of stars predicts that, at some time in the far distant future, our sun will gradually expand. As that happens, Titan will heat up, and that may be sufficient […]

This article attributes behaviors of earlier bedtime, longer sleeping, and earlier weaning to “greater personal independence” in children who sleep alone. It is equally possible that these behaviors are due to something else. Research predicting which children and families will benefit from co-sleeping or alone sleeping would be more useful. Heather Kuiper and Loren RauchOakland, […]

Your article reports that left brain areas normally associated with language comprehension are activated in shepherds who communicate in a whistled language.
