The Tangled Bank

Interested in biology, natural schience or medicine? Then take a look at The Tangled Bank. From PZ Myers’ introduction:

In cooperation with several other of us geeky science types, I am pleased to announce our own version of the “Carnival of the Vanities”….
Two things will distinguish us from the original “Carnival of the Vanities”: 1) we are specifically restricting ourselves to articles in the field of science and medicine, very broadly defined, and 2) we’ve got a different name.

PZ Meyers is hosting the first edition at Pharyngula.


Beware the Coin Toss

It looks like it isn’t quite fair:

The typical person flipping a coin varies enough in velocity, position, angle, and such to produce random-looking sequence. But when viewed this way, there is no reason for the flips to be precisely fair.
Now, with mathematician Richard Montgomery, Diaconis has shown that coin flips are in fact slightly biased to land on the same side as they started when flipped. By closely observing people flipping coins and carefully modeling the process, they estimate a bias on the order of 1�2%, dominating for example the house advantage in some casino games.

And if Diaconis is flipping they will land the way he wants them 100% of the time.

Junk Science

I am sure that there is a lot of junk science being performed in the world but the web site junkscience.com may not be the best place to get an objective evaluation of scientific research:

Unsuspecting visitors might think that Milloy�s site is devoted to criticizing shoddy science, but they would be wrong. If you look at what he �debunks� you will find that the real criterion for deciding what is �junk science� is not the quality of the work, but the political agenda that it might support.

As usual apply your critical thinking skills when visiting sites like junkscience.com and, well, apply them all the time.
