The Number

Whatever one's opinion of its possible limitations, the 2006 Iraq mortality survey produced epidemiological evidence that coalition forces have failed to protect Iraqi civilians... If, for the sake of argument, the study is wrong and the number of Iraqi deaths is less than half the infamous figure, is it acceptable that "only" 300,000 have died? Last November, with no explanation, the Iraqi Ministry of Health suddenly began citing 150,000 dead, five times its previous estimate. Is that amount of death acceptable? In January, the United Nations reported that more than 34,000 Iraqis were killed violently in the last year alone. Is that acceptable?
Regarding The Number, the result of what one of the study's authors calls an episode more deadly than the Rwandan genocide... [more within]

Iraqi Death Rate May Top Our Civil War: Deaths in Iraq: How Many, and Why It Matters

...Would it surprise you to learn that if the Johns Hopkins estimates of 400,000 to 800,000 deaths are correct -- and many experts in the survey field seem to suggest they probably are -- that the supposedly not-yet-civil-war in Iraq has already cost more lives, per capita, than our own Civil War (one in 40 of all Iraqis alive in 2003) ? And that these losses are comparable to what some European nations suffered in World War II ? You'd never know it from mainstream press coverage in the U.S. "Everybody knows the boat is leaking, everybody knows the captain lied," Leonard Cohen once sang. The question the new study raises: How many will go down with the ship, and will the press finally hold the captain fully accountable ?

This just in: Psilocybin can occasion mystical-type experiences having substantial and sustained personal meaning and spiritual significance

...Objectives    This double-blind study evaluated the acute and longer-term psychological effects of a high dose of psilocybin relative to a comparison compound administered under comfortable, supportive conditions...

Results    Psilocybin produced a range of acute perceptual changes, subjective experiences, and labile moods including anxiety. Psilocybin also increased measures of mystical experience. At 2 months, the volunteers rated the psilocybin experience as having substantial personal meaning and spiritual significance and attributed to the experience sustained positive changes in attitudes and behavior consistent with changes rated by community observers.

Conclusions   When administered under supportive conditions, psilocybin occasioned experiences similar to spontaneously occurring mystical experiences. The ability to occasion such experiences prospectively will allow rigorous scientific investigations of their causes and consequences.

Is God An Accident ? - Long Version

Despite the vast number of religions, nearly everyone in the world believes in the same things: the existence of a soul, an afterlife, miracles, and the divine creation of the universe. Recently psychologists doing research on the minds of infants have discovered two related facts that may account for this phenomenon. One: human beings come into the world with a predisposition to believe in supernatural phenomena. And two: this predisposition is an incidental by-product of cognitive functioning gone awry. Which leads to the question ...

Life On Mars's Meethane Traces Thought To Be Detected

Life on Mars? Methane has been found in the Martian atmosphere which scientists say could be a sign of present-day life on Mars. It was detected by telescopes on Earth and has recently been confirmed by instruments onboard the European Space Agency's orbiting Mars Express craft. Methane lives for a short time in the Martian atmosphere so it must be being constantly replenished. There are two possible ways to do this. Either active volcanoes, but none have yet been found on Mars, or microbes. The Independent has it as Methane find on Mars may be sign of life. The second group to detect signals of methane in the Martian atmosphere is led by Michael Mumma of Nasa's Goddard Space Flight Centre in Maryland, who used powerful spectroscopic telescopes based on Earth. This team is even believed to have detected variations in the concentrations of methane, with a peak coming from the ancient Martian seabed of Meridiani Planum, which is being explored by a Nasa rover. This could indicate a subterranean source of methane which is pumping out the gas, either due to some residual geological activity or because of the presence of living organisms producing it as a waste gas. Asked whether the continual production of methane is strong evidence of a biological origin of the gas, Dr Mumma said: "I think it is, myself personally." As to how...

Latro, Cerebrus, Suns New, Long and Short - Gene Wolfe

We believe that we invent symbols. The truth is that they invent us; we are their creatures, shaped by their hard, defining edges. When soldiers take their oath they are given a coin, an asimi stamped with the profile of the Autarch. Their acceptance of that coin is their acceptance of the special duties and burdens of military life--they are soldiers from that moment, though they may know nothing of the management of arms. I did not know that then, but it is a profound mistake to believe that we must know of such things to be influenced by them, and in fact to believe so is to believe in the most debased and superstitious kind of magic. The would-be sorcerer alone has faith in the efficacy of pure knowledge; rational people know that things act of themselves or not at all.

Quark Star and Strange Quark Matter

Quark Star Observations of two stars, one unusually small and the other unusually cold, have led astronomers to think they are seeing evidence of a new form of matter and a new kind of star, one possibly made of elementary particles known as quarks and denser than any cosmic object other than a black hole. (NYT link: yada yada) Here's a related link on neutron stars and quark matter. I rather like the phrase strange quark matter... Anybody else hear about this?

A Few Words About Jack Vance

A Few Words About Jack Vance. Gersen entered a hall with a floor of immaculate white glass tiles. On one hand was the display wall, characteristic of middle-class European homes; here hung a panel intricately inlaid with wood, bone and shell: Lenka workmanship from Nowhere, one of the Concourse planets; a set of perfume points from Pamfile; a rectangle of polished and perforated obsidian; and one of the so-called "supplication slabs"* from Lupus 23II.
* The nonhuman natives of Peninsula 4A, Lupus 23II, devote the greater part of their lives to the working of these slabs, which apparently have a religious significance. Twice each year, at the solstices, two hundred and twenty-four microscopically exact slabs are placed aboard a ceremonial barge, which is then allowed to drift out upon the ocean. The Lupus Salvage Company maintains a ship just over the horizon from peninsula 4A. As soon as the raft has drifted out of sight of land, it is recovered, the slabs are removed, exported and sold as objets d'art.
