Family members who perform the caregiver function usually pay a price because of the stresses involved. If “chronic adversity” is theorized to be the cause of a rise in a person’s IL-6, then questions for research include whether the IL-6 effect also applies to younger spouses and other family members, such as a child caring […]

SEVEN MUMMIES FROM TEXAS CAVE BROUGHT TO SMITHSONIAN Seven mummies preserved apparently by natural dryness of the Texas cave where they were buried, have just been received by the Smithsonian institution. The mummies shed new light on the prehistoric cave dwellers of the Big Bend region of Texas whose cave shelters have been explored in […]

Many men over age 50 rarely sleep through the night. Instead, they find themselves awake and needing to urinate when, as younger men, this rarely happened. The National Institute of Diabetes and Digestive and Kidney Diseases offers an excellent resource on the most common cause of frequent and urgent urination in men–benign prostatic hyperplasia, or […]

After reading your article, I am sure others must have also wondered if the “Tunguska meteor” that struck in Siberia in June 1908 might have been a mirror meteor. The mirror-asteroid strike described in the article sounds very much like descriptions of the event: tremendous energy and no impact crater. If a mirror object were […]

I was surprised to read about the extensive research in Puerto Rico that has found a link between phthalates in plastics and premature breast development in young girls. I was under the impression that a completely different culprit, growth hormones in chickens, was established many years ago. The article indicates that the San Juan researchers […]

Picture this: The year is 2700. A report is made of an “excavation of an 850-year-old site where butchered human skeletons have yielded evidence of cannibalism.” Corprolite discovered at the site contained “the chemical residue of human flesh.” A group of nomadic cannibals had briefly occupied an area known as Donner Pass. Perhaps prehistoric Anasazi […]

In your article, Lawrence Sirovich assumes that the degree of unpredictability shown in Supreme Court decisions results from judicial independence, with the implication that this is a good thing. That unpredictability could easily result instead from confusion caused by absent or conflicting principles in the justices’ political and juridical doctrines, a not-so-good thing. Alan EsworthyApex, […]

LIGHTNING Lightning, most awesome of the spectacular forces of nature, has yielded some of its mystery to science. But not all. We no longer credit it, as did our ancestors, to an angry Zeus or an impetuous Thor. Since Ben Franklin flew his adventurous kites, nearly two centuries ago, we know it is “made of […]

Meteorite Crater
The Barringer Crater in Arizona is one of the more famous geological sites on Earth. This Web site recounts the history and science of the crater’s formation 50,000 years ago and provides information about its discovery, its purchase by D.M. Barringer, and its current status.

This article exaggerates the capability of transmission electron microscopy by stating that “individual lithium ions” are seen. The research paper described says that the features imaged correspond to columns of lithium, cobalt, and oxygen atoms in a sample estimated to be 17 unit cells thick. Eliot D. SpechtOak Ridge National LaboratoryOak Ridge, Tenn. True, but […]

What a hope-inspiring article for those of us with celiac disease. Unfortunately, diagnosis often takes many years (approximately 16 years in my case), during which irreparable damage can occur. I suffered with anemia and fatigue for years and now have osteoporosis and osteopenia at age 45. It’s imperative to concentrate efforts on awareness, diagnosis, and […]

As a regular platelet-aphaeresis donor, I was alarmed by your article. I would be very curious to know if the standard tubing and centrifuge harness used for aphaeresis contain DEHP. During an aphaeresis session, roughly half the blood of the donor passes through a centrifuge to be relieved of platelets before being returned to the […]
