Sex differences in the adult human brain. It’s time for science to abandon the term ‘statistically significant’ The aim of science is to establish facts, as accurately as possible.

It’s time for science to abandon the term ‘statistically significant’

It is therefore crucially important to determine whether an observed phenomenon is real, or whether it’s the result of pure chance. If you declare that you’ve discovered something when in fact it’s just random, that’s called a false discovery or a false positive. And false positives are alarmingly common in some areas of medical science. In 2005, the epidemiologist John Ioannidis at Stanford caused a storm when he wrote the paper ‘Why Most Published Research Findings Are False’, focusing on results in certain areas of biomedicine.

In 2001, rumors were circulating in Greek hospitals that surgery residents, eager to rack up scalpel time, were falsely diagnosing hapless Albanian immigrants with appendicitis.

Lies, Damned Lies, and Medical Science - David H. Freedman

At the University of Ioannina medical school’s teaching hospital, a newly minted doctor named Athina Tatsioni was discussing the rumors with colleagues when a professor who had overheard asked her if she’d like to try to prove whether they were true—he seemed to be almost daring her. She accepted the challenge and, with the professor’s and other colleagues’ help, eventually produced a formal study showing that, for whatever reason, the appendices removed from patients with Albanian names in six Greek hospitals were more than three times as likely to be perfectly healthy as those removed from patients with Greek names. “It was hard to find a journal willing to publish it, but we did,” recalls Tatsioni.

And then there is this. A good thought project for Lent. As you watch the animation, as you watch the little dot planets whirl about the Sun, and the Sun on the galactic plane go zooming along in its own snaky path, consider how many times you see the planets circle the Sun and then consider the span of your life… … after which you are going before the Judge, through whom all things came into being.

Scientific Regress by William A. Wilson

Last summer, the Open Science Collaboration announced that it had tried to replicate one hundred published psychology experiments sampled from three of the most prestigious journals in the field. Scientific claims rest on the idea that experiments repeated under nearly identical conditions ought to yield approximately the same results, but until very recently, very few had bothered to check in a systematic way whether this was actually the case.

That's the thesis of a must-read article in First Things magazine, in which William A. Wilson accumulates evidence that a lot of published research is false.

Many clergy have made enormous contributions to science In a previous post I discussed the life and work of Georges Lemaitre, the Belgian Jesuit and cosmologist. Lemaitre’s work and faith challenges the idea, proposed by New Atheism, that religion and science are in conflict. File:Observable universe logarithmic illustration.png. An Atheist Questions the Logic of Darwinism (Part 1) Evolution, as understood in the popular circles as purely random physical mutations filtered by natural selection, is increasingly under attack. It’s defenders must continue to climb further onto a limb and make explanations that taste more and more like just-so stories. One recent attack on evolution comes from atheist philosopher Thomas Nagel who wrote the book Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature is Almost Certainly False.

Nagel’s explanations are reasonable, but written as a philosopher who sometimes paints in broad strokes. His conclusions, however, are strong enough to deserve attention from the Darwinists. Nagel is no religious zealot, for he clearly states what he would conclude if left to his own personal desires: “My preference for an immanent, natural explanation is congruent with my atheism.” The Space Doctor’s Big Idea. There once was a doctor with cool white hair. He was well known because he came up with some important ideas.

He didn’t grow the cool hair until after he was done figuring that stuff out, but by the time everyone realized how good his ideas were, he had grown the hair, so that’s how everyone pictures him. He was so good at coming up with ideas that we use his name to mean “someone who’s good at thinking.” Two of his biggest ideas were about how space and time work. This thing you’re reading right now explains those ideas using only the ten hundred words people use the most often.1 The doctor figured out the first idea while he was working in an office, and he figured out the second one ten years later, while he was working at a school. The first idea is called the special idea, because it covers only a few special parts of space and time.

Scientists extract images directly from brain. Researchers from Japan's ATR Computational Neuroscience Laboratories have developed new brain analysis technology that can reconstruct the images inside a person's mind and display them on a computer monitor, it was announced on December 11.

According to the researchers, further development of the technology may soon make it possible to view other people's dreams while they sleep. The scientists were able to reconstruct various images viewed by a person by analyzing changes in their cerebral blood flow. Using a functional magnetic resonance imaging (fMRI) machine, the researchers first mapped the blood flow changes that occurred in the cerebral visual cortex as subjects viewed various images held in front of their eyes. Subjects were shown 400 random 10 x 10 pixel black-and-white images for a period of 12 seconds each. For now, the system is only able to reproduce simple black-and-white images. Does Quantum Mechanics Speak to Catholic Teaching? On the right-hand column you'll see that of the five posts most visited on this blog, three deal with quantum mechanics and religion.

If, then, the relation between quantum mechanics and Catholic doctrine is intriguing, why not explore a general question: does quantum mechanics inform theology, and if so, how?
