This article barely scratches the surface of the problem. What is stopping someone from gene splicing the disease of choice onto heat-loving bacterium? Something that can live near the 600°F of melting lead will certainly survive the standard hospital-sterilization process. D.J. KavaBeaumont, Texas The statement “2 tons of ore from ocean sites should yield as […]

I was surprised you didn’t mention the effect of salinity in ocean water in this article. Warming climate has melted much of the glaciers, bringing fresh water into the North Atlantic. That water isn’t dense enough to sink and carry on the conveyor belt that usually brings warm currents from the tropics. This slowing of […]

The experiments with mice infected with the 1918 influenza virus are important but not surprising. John Barry’s The Great Influenza: The Epic Story of the Deadliest Plague in History (2004, Viking) explains that many, perhaps most, of the victims were killed by the overreaction of their immune systems. This may be why most of the […]

I was extremely disappointed to read the definition of ecotourism as being “the practice of visiting sites where exotic landscapes and rare animals are the main attractions.” Ecotourism was founded with the specific goal of countering the overuse of the kind of travel described in the article. A better definition would be one used by […]

The “mystical journey” described in this article has long been available drug free and under carefully controlled conditions via biofeedback. The results of these sessions are very similar to those described by people who received psilocybin. In the rare circumstances when clients become uncomfortable in their altered states, a session can be terminated immediately. Doreen […]

Letters from the September 30, 2006, issue of Science News
Not a pretty picture “Deadly Disorder: Imagined-ugliness illness yields high suicide rate” (SN: 7/22/06, p. 52) raises some questions. What about people who are physically unattractive—those whom a majority of the society considers ugly? I suspect that many people treated for body dysmorphic disorder (BDD) are unattractive by that definition. The psychiatric profession tends to […]

This article states that gamma-ray bursts are “a million trillion times as bright as the sun.” The sun is so bright that humans can’t look directly at it from 93 million miles away. How can we possibly wrap our minds around something a million trillion times brighter? Astronomy is great. Donald KaufmannPhiladelphia, Pa. ?

This article says that people with bipolar disorder tend to have more lost workdays than those with major depression do. The data shows this is true. However, the authors point out that in the sample of 3,378 workers, 1 percent suffered from bipolar disorder while 6 percent experienced major depression. Clearly, the greater impact on […]
