In the space of a single paragraph, you report that the National Academy of Sciences and the United Nations conclude that human activity “very likely” has caused global warming and that “uncertainties remain about the role of human-generated gas emissions.” One can’t have it both ways. Given the uncertainties involved, President Bush is following the […]

With reference to the opinion that hemophiliacs might have expected to feel better and been less likely to treat themselves for internal bleeding following a form of gene therapy, I can only object to the suggestion that hemophiliacs can feel-better themselves out of an internal bleed. As a mother and grandmother of hemophiliacs who coped […]

The interesting article “Survey probes cosmos from near to far” set me to tilting at windmills. Even before it’s completed, the professional astronomers managing the Sloan Digital Sky Survey should enlist amateur astronomers as asteroid hunters in a way similar to how they’re mobilized by the SETI@home project to search for intelligent signals from space. […]

It was a bit of a shame that the fossil-trackway site pictured on the cover of the June 9 issue was not identified, as it is one of the more remarkable ones ever uncovered in North America . The tracks shown are a few of hundreds across the floor of a quarry near Culpeper, Va. […]

Pluto is distinguished by properties other than its size, and its representation in “Nine planets, or eight?” as just another gray ball was misleading. It has the most contrasting surface known in the solar system (bright nitrogen ice caps and dark carbonaceous equatorial areas). To understand the processes ongoing on Pluto’s surface and within its […]

Regarding this article, wherein Cosmic Background Explorer (COBE) findings are surpassed by BOOMERANG (Balloon Observations of Millimeter Extragalactic Radiation and Geophysics) data, can you help me understand what happened to the Microwave Anistropy Probe (MAP)? It was expected to surpass COBE in many ways. MAP was to launch in November 2000, establish a sun-sheltered position […]

“Dirty money harbors bacterial dangers” brought back memories of my beloved grandmother in the 1920s. She always washed and ironed her dollar bills because she considered them to be unsanitary. F. Eleanor Warner Northport, Maine

“Salmon hatcheries can deplete wild stocks” ignores a basic fact. Hatchery stocks came from wild stocks. Their DNA is the same. There is an abundance of underused habitat in our northwest rivers. Some hatchery salmon would use these habitats if they were left alone. Instead, hatchery fish are clubbed to death to prevent their mixing […]

As an insect taxonomist, I was amused by your article about whimsical scientific names but disappointed that one of my favorites was not mentioned: the wasp Iaha ha. Sandra Shanks San Francisco, Calif. Three observations on your article: 1) Linnaean names, at their best, tell you something about the creature that is named. Thus while […]

I read the article “Look on the bright side and survive longer” with interest but was given pause by the fact that the nuns knew their autobiographies were “to be read by the congregation’s Mother Superior.” I think this may seriously undermine the conclusions drawn. Even without this problem, I think a basic distinction should […]

In “Many refugees can’t flee mental ailments,” Bhutan is greatly maligned. Equating Bhutan’s story with the Cambodian genocide, as the article does, is like equating a Fourth of July firecracker with the atomic bomb. Tiny, Tibetan, Buddhist Bhutan, with a population of only 650,000, is struggling to survive between giants China and India and among […]

Please explain a curious statement in “A more perfect union.” The article paraphrases Jonas Sandstrom of Uppsala University in Sweden as suggesting that an “endosymbiont’s isolation may be a one-way ticket to extinction. Once the bacterium loses genes . . . it has no way of getting them back. It can’t, therefore, evolve away from […]
