If anything, preschool may do lasting damage to many children. A 2005 analysis by researchers at Stanford University and the University of California, Berkeley, found that kindergartners with 15 or more hours of preschool every week were less motivated and more aggressive in class. Likewise, Canada’s C.D. Howe Institute found a higher incidence of anxiety, hyperactivity and poor social skills among kids in Quebec after universal preschool.

Their story was told in a book my buddy Lt. Gen. Hal Moore and I wrote 15 years ago titled “We Were Soldiers Once . . . and Young” and in the Mel Gibson movie, “We Were Soldiers,” released in the spring of 2002. Too Tall and Old Snake were ably portrayed in the movie.
Their argument over which of them is the Best Pilot in the Whole World sadly came to an end this week when our friend and comrade-in-arms Maj. Ed (Too Tall to Fly) Freeman slipped the surly bonds of earth and headed off to Fiddler’s Green, where the souls of departed cavalrymen gather by dispensation of God Himself.
Too Tall Ed was 80 years old when he died in a hospital in Boise, Idaho, after long being ill with Parkinson’s disease. He turned down a full dress hero’s funeral in Arlington National Cemetery in favor of a hometown service and burial in the National Cemetery in Boise, close to the rivers he loved to fish and the mountains he flew through in his second career flying for the U.S. Forest Service.

Something beneath the surface is changing Earth’s protective magnetic field, which may leave satellites and other space assets vulnerable to high-energy radiation.
The gradual weakening of the overall magnetic field can take hundreds and even thousands of years. But smaller, more rapid fluctuations within months may leave satellites unprotected and catch scientists off guard, new research finds.
A new model uses satellite data from the past nine years to show how sudden fluid motions within the Earth’s core can alter the magnetic envelope around our planet. This represents the first time that researchers have been able to detect such rapid magnetic field changes taking place over just a few months.
Long time readers will remember that Full Circle was one of our first essays of the week back when we were getting started. Now Rundy (The Silverware Thief) has a web site up devoted to chronicling his care for Grandpa called As We Lived Before. Most of the essays on this site have never been made public before now. That includes this week’s essay of the week entitled “Bad Night, Bad Day.”
Britain’s honeybees have suffered catastrophic losses this year, according to a survey of the nation’s beekeepers, contributing to a shortage of honey and putting at risk the pollination of fruits and vegetables.
The survey by the British Beekeepers’ Association (BBKA) revealed that nearly one in three of the UK’s 240,000 honeybee hives did not survive this winter and spring.

From an analysis of the skeletons and pottery, scientists identified the two successive cultures that occupied the settlement. The Kiffians, some of whom stood up to six feet tall, both men and women, lived there during the Sahara’s wettest period, between 10,000 and 8,000 years ago. They were primarily hunter-gatherers who speared huge lake perch with harpoons.
I don’t don’t that Sahara was wet at one time. But I do doubt that a culture where people where often in the 6 foot tall primarily ate fish that they speared with harpoons.
Not to be perjorative–it is. Go learn something random and useless.
The research found that the Pill can alter the type of male scent that women find most attractive, which may in turn affect the kind of men they choose as partners. It suggests that the popular form of contraception — used by a quarter of British women aged between 16 and 50 — could have implications for fertility and relationship breakdowns.
Recent news stories are all about how jogging can prevent aging. But I wonder how much of that can be attributed to exercise and how much of that can be attributed to being outdoors. From Eurekalert
Researchers at Johns Hopkins are reporting what is believed to be the most conclusive evidence to date that inadequate levels of vitamin D, obtained from milk, fortified cereals and exposure to sunlight, lead to substantially increased risk of death.
In a study set to appear in the Archives of Internal Medicine online Aug. 11, the Johns Hopkins team analyzed a diverse sample of 13,000 initially healthy men and women participating in an ongoing national health survey and compared the risk of death between those with the lowest blood levels of vitamin D to those with higher amounts. An unhealthy deficiency, experts say, is considered blood levels of 17.8 nanograms per milliliter or lower.
Of the 1,800 study participants known to have died by Dec. 31, 2000, nearly 700 died from some form of heart disease, with 400 of these being deficient in vitamin D. This translates overall to an estimated 26 percent increased risk of any death, though the number of deaths from heart disease alone was not large enough to meet scientific criteria to resolve that it was due to low vitamin D levels.
Yet, researchers say it does highlight a trend, with other studies linking shortages of vitamin D to increased rates of breast cancer and depression in the elderly. And earlier published findings by the team, from the same national study, have established a possible tie-in, showing an 80 percent increased risk of peripheral artery disease from vitamin D deficits.
In view of the above, it is ironic that this article views all the sunshine that joggers get as the one negative aspect of jogging.
But the charlatans are only half the story. Courts have also missed plenty of mistakes from well-intentioned, conscientious scientists, too. In fact, these may be even more common—and harder to catch. Studies show that crime lab fiber, paint, and body fluid analyses, for example, may consistently have error rates of 10 percent or higher. The error rate in fingerprint analysis is possibly between 1 percent and 4 percent. And bite mark evidence is notoriously unreliable though still widely used.
