Simple Answers to Complex Medical Questions

There’s a new medical study of the effects of alcohol consumption that finds a surprising result: Controlling only for age and gender, compared to moderate drinkers, abstainers had a more than 2 times increased mortality risk, heavy drinkers had 70% increased risk, and light drinkers had 23% increased risk. A model controlling for former problem […]

1491 by Charles C. Mann

We picked up a used copy of Charles Mann’s pop-archeology book 1491: New Revelations of the Americas Before Columbus a while back. I didn’t read it at the time, because I was a little afraid that it would be rather polemical in what I think of as the Neil Young mode– wildly overstating the awesomeness […]

The nice thing about using actual poll services for this sort of thing, though, is that I can re-post […]

Amazing Laser Application 4: Optical Tweezers!

What’s the application? Optical tweezers use focused light beams to trap small particles in the focus of the beam, and drag them around by moving the beam. What problem(s) is it the solution to? 1) “How do we move these tiny little things around without touching them?” 2) “How do we measure the forces exerted […]

Public Knowledge of Science: The More Things Change, the More They Don’t

The NSF’s Science and Engineering Indicators report came out not too long ago, and the bulk of it is, as usual, spent on quasi-quantitative measures of scientific productivity– numbers of degrees granted, numbers of patent applications for various countries, etc. I find all of those things pretty deeply flawed, so I tend to skip past […]
