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 ...

It’s been a staple gag of TV sitcoms for years: an older character walks into a room and says, “Now, what did I come in here for?”
But gags like that are funny because they have a grain of truth in them, and increasingly, I’m finding that grain of truth sticking in my own aging gullet.
Of course, when an oyster finds an irritant in its gullet, it turns that oyster into a pearl. My equivalent is turning it into a science column. (Albeit obviously not one focusing on the biology of the oysters, since even if they have gullets, I’m pretty sure that’s not where they make pearls.)
As it ...

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 ...

Whenever I say anything is impossible, I always think of Arthur C. Clarke’s First Law: “When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.”
Up until recently, I would have said mind-reading was impossible...but, even though I am neither distinguished, elderly, nor a scientist, it’s beginning to appear as if it may not be impossible forever. Why? Because scientists have successfully reconstructed videos of what people have seen, simply by scanning their brain activity.
Sure the resulting video is extremely blurry, but like a singing dog, it’s not so much that it sings well as the fact it sings at all that is ...

A few years ago (35 still counts as a few, right?) I was valedictorian for my high school class. This entailed making a speech. Since the theme of our class was “Climb Every Mountain” (why, yes, we had produced The Sound of Music that year; how did you guess?), my speech was based on an extended metaphor: high school as a place of mountain-climbing instruction.
I’d love to tell you exactly what I said, but I think the paper I wrote the speech on crumbled to dust long ago. Still, I’m pretty sure I expressed optimism about the future and said something about “scaling peaks” and “reaching for the sky” and ...

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 ...

You know, it’s not easy being a writer.
Oh, I know, it doesn’t rank up there with, say, coal miner in physical difficulty or neurosurgeon in mental difficulty, but where it probably has it over both of them is in creative difficulty: the pressure to constantly come up with something new.
Heck, as a science fiction and fantasy writer, I’m expected to create entire worlds, whole solar systems, mythical creatures and believable characters out of nothing more than my own brain cells.
Wouldn’t it be great if there were some way to artificially stimulate creativity?
Turns out, there may be.
In a
paper published earlier this month in PLoS One, an online ...

Now that we’re finally starting to see some hot weather, it won’t be long before we begin to see something else: thunderstorms and lightning (very, very frightening me! Galileo, Galileo...sorry, just a little Queen flashback).
It’s the lightning, of course, that makes thunderstorms thunder. If I may quote myself from a previous column, lightning “is a massive but short-lived electrical discharge in the atmosphere, usually several kilometres long.
“Lightning arises because of a charge separation in a cloud. A ‘charge separation’ just means that there are more electrons in one place than another. Cloud-to-ground lightning occurs when there are lots of free electrons in the base of the cloud. These electrons are discharged in what is called a stepped leader: ‘stepped’ ...
