This report reminded me of similar studies demonstrating longer life in people who own pets. Has anyone compared these studies and looked for causes of the increased life span in common in these two populations? Such things as increased opportunities of emotional expression, getting out of the house on a regular basis, or adapting to […]

Eskimos are reported to occasionally tie female Malamutes in heat out in the wilderness to be impregnated by wolves. This is supposed to keep their dog lines vigorous. The converse, male Malamutes impregnating female wolves, is not reported. If this process has happened widely in history, then there may have been three dog Eves in […]

Bacillus cereus is not a “harmless” microorganism, as stated in your article. It has been described in the ophthalmologic literature as one of the most destructive organisms if it gains access to the inside of the eye, and it is a relatively common cause of posttraumatic endophthalmitis. There is a high incidence of B. cereus […]

Gene therapy grows bone in mice and rats
A new gene therapy tested in rodents regrows bone by transforming skin and gum cells into bone-making cells or into cells that mass-produce a molecule called bone morphogenetic protein-7, which induces bone growth.

A PHARAOH’S TOMB The picture on the cover of this week’s SCIENCE NEWS-LETTER shows how an archaeologist masters the “human fly” trick when he must measure the stones that form the sloping walls of a pharaoh’s tomb. The scene is the famous pyramid at Meydum, Egypt, supposedly built by King Snefru. The Museum of the […]

Toxicology Game
The University of Washington’s evolving Project Greenskate Web site gives students the chance to investigate potential health concerns surrounding the hypothetical development of a city park on a former industrial site. They visit various fictitious places, such as the Department of Environmental Quality, City Hall, a Community Center, and the local high school, to obtain […]

NOBEL PRIZE IN CHEMISTRY IS AWARDED DR. LANGMUIR The award of the 1932 Nobel Prize in Chemistry to Dr. Irving Langmuir, the General Electric Research Laboratory chemist, adds laurels to a system of investigation of nature’s secrets as it recognizes a great scientist. Langmuir has never been a mere inventor or applier of knowledge to […]

In regard to the ability of people unable to speak a language to detect lying, this may be a result not of their inability to speak or understand any language but merely their inability to speak or understand the language the speakers were using. Some years ago, while visiting Japan, I saw a television show […]

This article asserts that the earliest photographic image was taken in 1826. In fact, the earliest photographic image may date to much earlier. Using silver nitrate on linen (1992) and later silver sulfate (1994), Nicholas P.L. Allen was able to reproduce, in large part, the unique visual and chemical properties of the Shroud of Turin. […]

I think it’s more than coincidental that the sound repertoire of babbling babies, compared with the speech sounds in a diversity of languages across the world, lends credence to the idea that there was a mother tongue that goes back to prehistoric times. Readers of the Bible will recall that it was after the fall […]
