Recent correspondence directed me to the fact that there is a Philosophy section in Scientific Blogging. This is something I have kept away from, since my view of the subject follows the Pooh-Goethe paradigm [1]. However, I have just read In The Beginning - A Rough Guide To A Physicalist View Of Everything which introduced the subject of metaphysics. Now it may be customary to think that metaphysics is “that which lies beyond physics”, so the more we get our physics right, the better the metaphysics. But then Darwin had a different perspective. In his Notebook M (1838) he wrote

To test whether my belief that homeopathy is not an evidence-based rational system of medicine is reasonable or just prejudice on my part, I did a quick experiment using Google Scholar. (This was done Jan 17, 2008)

A "layman's meta-analysis" of sorts. Not supremely scientific alas (although perhaps somewhat reminiscent of a GCSE science project ), but the best I could do early in the morning with only vending-machine coffee to keep my brain from sleep ;-) 

Tyrannosaurus rex has had an interesting few weeks - Raptorex kriegsteini, a man-sized ancestor, was unveiled a few weeks ago and now we find out that Alioramus altai—a horned, long-snouted, gracile cousin of Tyrannosaurus rex—shared the same environment with larger, predatory relatives.

Tyrannosaurs are bipedal predators that lived at the end of the Cretaceous (from 85 million years to approximately 65 million years ago) is currently known from several groups of fossils. One subfamily from North America includes Albertosaurus and Gorgosaurus, while the other subfamily bridges Asia and North America and includes Tyranosaurus, Tarbosaurus, and Alioramus.

Both T.

Outreach campaigns like 'Rock the Vote' don't generally do a lot for the image of young voters - if you're in the tank for one party the other party gives up on you and your own party takes you for granted because they are going after undecided people in swing states who keep their votes up for grabs.   But get-out-the-vote campaigns are essential, politicos say, because students are flaky, so if they're in your party you don't have to listen to them on issues but you have to rent a bus, take them to the booths and buy them a sandwich to get them to actually vote.

Can air pollution trigger appendicitis?  Yes, says a study conducted by researchers at the University of Calgary, University of Toronto and Health Canada who looked at 5191 adults admitted to hospitals in Calgary, Alberta, Canada.

Fifty-two per cent of admissions occurred between April and September, the warmest months of the year in Canada during which people are more likely to be outside.

Therefore, air pollution must be the culprit if your correlation-causation arrow is more like a Scud missile.

Sitting up straight in a chair is obviously good for posture but it can also make you unconsciously more confident, say Ohio State University researchers.   

They found that people who were told to sit up straight were more likely to believe thoughts they wrote down while in that posture concerning whether they were qualified for a job while those who were slumped over their desks were less likely to accept written-down feelings about their own qualifications.

The results are an indication that our body posture can affect not only what others think about us, but also how we think about ourselves, said Richard Petty, co-author of the study and professor of psychology at Ohio State.

You would think religious people and atheists don't have a lot in common regarding thinking but they do, says a study by UCLA, Pepperdine and USC neuroscientists.    

It's tough to systematically compare religious faith with ordinary cognition, so calibrate accordingly, but in a neuroimaging study the researchers found that while the human brain responded very differently to religious and nonreligious propositions, the process of believing or disbelieving a statement, whether religious or not, was governed by the same areas in the brain. 

The power of quantum mechanics for data transmission is intriguing because of potential for secure, high speed communications but current storage and transmission of quantum information is far too fragile to have any practical value in the near term.

In classical communications, a bit can represent one of two states - either 0 or 1. But because photons are quantum mechanical objects, they can exist in multiple states at the same time. Photons can also be combined, in a process known as entanglement, to store a bit of quantum information (i.e. a qubit). 

We have all heard the term, "Nutty Professor", which brings to mind the highly intelligent, yet socially inept individual; excelling in the academic world, yet failing miserably in the realm of common sense. Is there an evolutionary explanation for why this phenomenon exists?

Bruce Charlton, Editor-in-Chief of the journal Medical Hypotheses, says "yes". He calls these people 'Clever Sillies' in his article, "Clever Sillies- Why the High IQ Lack Common Sense". He proposes that high IQ is not just a cognitive ability, but also a cognitive disposition. He says,

In previous articles we examine how the brain behaved detrimistically and also how training and indoctrination would affect the information stored. In considering choices an important distinction needs to be made to avoid confusing "choices" with "decisions".  In particular, the point regarding choices is that they are made well before a decision arises.
