Every Christmas/New Year’s holiday season brings with it a spate of articles about alcohol—you know, like this one.
Alcohol is a very odd thing for us to imbibe, when you come right down to it. It is, after all, the waste product of another life-form: namely, yeast. There are very few other life forms whose waste products we willingly take into our body. So why do we do it?
The answer, of course, is that this particular waste product produces interesting side-effects when ingested: side-effects that humans discovered very, very early on (beer and wine-making were already well-established in the Middle East by 1500 B.C.).
Although alcohol, like barbiturates, tranquilizers and anesthetics, is ...

As any wife will tell you, men are lousy at being sick. They swear they’re on death’s door when it is quite apparent to their long-suffering significant other that in fact they are suffering from nothing more than a cold, nowhere near as bad as the one she had the week before when she not only went to work every day, she cleaned the house, did the grocery shopping, and took the kids to school, dance and piano lessons and hockey practice—which, come to think of it, she’s doing again this week. So, really, so what if he’s sick, since who can tell the difference? Well, the difference ...

Human beings have been using and abusing alcohol for a very long time: roughly 10,000 years, give or take a long weekend.
The effects of drinking too much of the stuff have been known for every one of those 10,000 years (although individuals somehow seem to forget them within a remarkably short time frame).
For decades, scientists have been trying to understand the mechanism behind the reduced muscle coordination and sedative effects of alcohol. The assumption has been that alcohol acts on the brain’s neurons, but nobody could figure out exactly how.
A new study indicates that may be because they’ve been looking in the wrong place. Not only that, the ...

[podcast]http://edwardwillett.com/wp-content/uploads//2011/09/Gait-Recognition.mp3[/podcast]
Twelve years ago, I started a science column with this sentence: “Are you fed up with having to carry 2,762 separate plastic cards in your wallet for buying gas, getting Air Miles, withdrawing money, renting videos and collecting frequent-ice-cream-eater points? Then you'll be glad to hear about biometrics...”
More than a decade later, I can’t help but notice that I still have 2,762 separate plastic cards (a rough approximation, admittedly). But work continues on biometrics, and a new study describes a promising new way to use biometrics to pinpoint identity: gait recognition.
Biometrics (as I wrote 12 years ago) “is the measurement of tiny differences among individuals for the purposes of identification. ...

It’s summer, that time of year when belly buttons escape their natural habitat of swimming pools and beaches and wander free in the oddest places, from the library to the shopping mall (although unlike the grins of Cheshire cats, they rarely appear without their owners).
But as you survey these navel maneuvers, don’t think of them merely as evidence that humans are viviparous. Instead, marvel at the fact that every belly button you see, as well as all those which, thankfully, you don’t, are unique habitats, rather like zoos in miniature.
We know that thanks to the efforts of a group of biologists and science communicators from North Carolina State ...

Some people are easily embarrassed. Some, not so much. I, for example, have no problem at all singing in public. (
Here's proof!). That's not true for everyone.
Which is why, I guess, that researchers studying the neurological basis of embarrassment recently chose to trigger embarrassment by making people listen to recordings of themselves singing. Oh, the horror!
Apparently it's a pretty reliable way to make people feel embarrassed, although I'm not sure how they screen for people like me who actually enjoy listening to recordings of ourselves.
Anyway, the method of engendering embarrassment wasn't really the point of the study (although it's certainly why I noticed it). The ...

Exercise is good for you. It’s a shame, since I personally find the whole sweating/breathing hard/ hurting thing a (literal) pain, but I don’t believe I can mount a successful argument as to why sitting on your rear end eating junk food all day is actually better for you, even though evolution seems to have inclined us to do it.
(It’s interesting to note that “survival of the fittest” is only one letter away from “survival of the fattest,” and one reason we’re so fond of high-calorie foods is that when food is in short supply, it really is the fattest who are the fittest to survive. But I digress.)
I’m not ...

Ah, New Year’s. A time for resolutions, typically focused on living more healthily.
Apparently the Canadian Broadcasting Corporation, not trusting us to do it ourselves, has decided to make our resolutions for us: it’s started 2011 with a series of stories lecturing Canadians on how unhealthy their lifestyle is, and started something called the “Live Right Now” initiative.
Yes, apparently determined to live up to its nickname as “The Mother Corp.,” CBC is telling us to eat our vegetables, quit watching TV and go outside and play, always wear clean underwear in case we’re hit by a truck (OK, I may have made that one up) and, most motherly of all, to “Go to bed, it’s past your bedtime!”
Apparently a CBC poll ...

Just a couple of years ago, I wrote a column about the advent of tearless onions that included some background on why onions make us cry in the first place. Ordinarily I wouldn’t revisit a topic quite so soon, but you know how it is with science: things change fast, and just this week there was breaking news in the field of onion-induced tears.
Well, as breaking as any news can be when it deals with something that’s been around for half a billion years.
Onions have always made humans cry, or at least for as long as humans have been eating them, which seems to be a long time indeed—so far back in pre-history that we can’t even say for sure ...
