The urination constant

I am a squeamish person, and I dislike talking about bodily functions.  But I stumbled upon a finding that is so interesting that I had to share it with you.  Did you know that virtually all animals, from a dog to an elephant–including human beings–take about the same amount of time to urinate?  That would be around 21 seconds.  See why after the jump.

Psychology experiments often can’t be replicated

There is currently what is being described as a “crisis” in the field of social/personality psychology.  It turns out, many psychological experiments, however heralded in the media and whose findings are made a big deal of, cannot be replicated by other researchers.  Is that due to fraud?  Statistical quirks? Or does it mean that psychology is not a science after all? [Read more...]

The failure of reality to match up with computer models

The ice caps are supposed to be melting.  But the ice in Antarctica is at record levels.  And the ice at the North Pole, after declining for awhile, is back to normal levels.  So reports a British newspaper, the Register.  I’m struck, though, by a comment in the article that cites,  “This failure of reality to match up with climate modelling.”

That “reality” has somehow failed is rather humorous.  Isn’t computer modelling dependent on what data is programmed into the model?  And isn’t reality always going to be more complex than a model, with far more variables, many of which are unknown to the researcher?  [Read more...]

Both matter and anti-matter

Paradox of nature:  a sub-atomic particle has been discovered that acts like both matter and anti-matter. [Read more...]

Why do we sleep?

Virtually all living organisms sleep, or its equivalent.  But it has been a puzzle why.  Surely spending a big part of every day unconscious can’t have much survival value.  But scientists have now discovered that sleep is when our bodies repair themselves and when our brain is rejuvenated and, literally, cleansed.

Time has a fascinating article on the subject, linked and excerpted after the jump.  Type-A personalities who brag about how little they sleep so they can work more, party animals who stay up all night, commuters who stay up late and get up early, and college students in general would do well to read it.
