Everyone is bored sometimes. You find yourself at loose ends, with nothing to read, nobody to talk to, and maybe not even anything interesting to look at...driving alone from Regina to Saskatoon, for example.
Yet science has carried out relatively little research on boredom. About four years ago, Richard Ralley, a lecturer in psychology at Edge Hill University in England, set out to change that. Ralley believes that boredom must serve a useful purpose, or it wouldn’t have evolved. He suspects it may be a matter of energy conservation: boredom is the brain’s way of telling the body it’s time to rest, that the task it’s engaged in isn’t worth the expenditure of energy.
Some positive aspects of boredom have been identified ...

How often has this happened to you?
“So I was talking to...to...oh, you know, that guy, the one in the head office, big hair, bad teeth, only listens to Perry Como records...geez, why can’t I remember his name? It’s on the tip of my tongue!”
It’s a common phenomenon, and it’s not just people's names. Sometimes you can’t think of the name of a place, or a food, or a car, or...just about anything. You can feel that the information is in your head, but you can’t shape it into a word.
It may be a well-known phenomenon, but it isn’t well-understood. However, new research may have shed a little light on the mechanism involved.
One leading explanation for tip-of-the-tongue torment is that when ...

[podcast]http://edwardwillett.com/wp-content/upLoads//2010/02/Frisbee.mp3[/podcast]
Fred Morrison died on Tuesday at the age of 90, one of those people you may never have heard of, but really should have.
Morrison invented the Frisbee.
Since millions of these and other flying discs have been sold since the 1950s, it’s perhaps a bit humbling to discover, though, that even though throwing a Frisbee well is a skill that can be acquired, nobody has pinned down all the details of the science involved.
Morrison, born in Richfield, Utah, said the inspiration for the Frisbee went back to a Thanksgiving Day picnic in 1937 when he and his girlfriend (and future wife), Lu Nay, began throwing the lid of a popcorn tin back and forth.
They soon found that a tin cake pan ...

[podcast]http://edwardwillett.com/wp-content/upLoads//2010/02/Spray-on-Liquid-Glass.mp3[/podcast]
“Spray-on liquid glass” sounds like a product you’d see advertised at two o’clock in the morning in an infomercial.
It sounds even more like a 2 a.m. infomercial product when you see headlines about it that claim it is “about to revolutionize everything.”
Maybe it’d sound more impressive if I used its more formal name, which is “SiO2 ultra-thin layering,” but that’s hard to type, so I’m going to stick with “spray-on liquid glass.”
Besides, that’s exactly what it is: an extremely thin layer of glass that can be sprayed onto...well, just about anything.
Though it was invented in Turkey, the patent for spray-on liquid glass is held by the German company
Nanopool.
It consists of almost pure silicon dioxide, a.k.a. silica, extracted ...

[podcast]http://edwardwillett.com/wp-content/upLoads//2010/01/Fuel-from-Germs.mp3[/podcast]
For years, we’ve been turning crops such as corn, wheat and sugar beets into fuel, using yeast to convert sugar into alcohol.
But there’s an obvious problem with this. That stuff we’re turning into fuel is also food for humans and feed for animals.
(And as an aside, how come we always call it “animal feed” as opposed to “animal food”? And why don’t we ever refer to “human feed”? Hmm?)
A lot of the plant is wasted when you grow crops for fuel or food. The leaves and stems, with their tough cell walls made of cellulose, hemicellulose and lignin, are more of a nuisance than anything else. Wouldn’t it be great if there were a use for what is now plowed ...

Parents (I don’t think I’m giving away any parental secrets here) worry about peer pressure--not least because parents remember how much their behavior was influenced by peers when they were young.
The fact is, we’re all influenced by the people around us...and we often think of that influence as a bad thing.
As the Bible puts it, “Evil companions corrupt good morals.” And other kinds of companions can have other effects.
For instance, an analysis of 12,067 people that appeared in The New England Journal of Medicine in 2007 revealed that you are more likely to be obese if your best friend is obese. (Overstuffed siblings or spouses also makes a difference, but the greatest negative effect comes from fat friends.)
To a certain ...

[podcast]http://edwardwillett.com/wp-content/upLoads//2010/01/Why-Im-Not-Stephanie-Meyer.mp3[/podcast]
I’m a full-time writer, but not, alas, a fabulously wealthy and/or successful one. James Cameron isn’t bugging me about film rights; Oprah isn’t plugging me on TV; fans aren’t lugging great stacks of my books around, chasing me for autographs.
It’s easy, when you’re one of the little guys in any creative field, be it fashion, books, movies or music, to envy the runaway successes and wonder what, for example, Stephenie Meyer’s got that you ain’t got. Are her books, objectively, truly so much better than everyone else’s? Or, more to the point, than mine?
Probably not, suggests recent research: in fact, runaway successes are runaway successes in part because they’re runaway successes...and efforts to figure out what “the next big thing” ...

[podcast]http://edwardwillett.com/wp-content/upLoads//2009/12/Why-We-Overeat.mp3[/podcast]
Put on a few extra pounds over Christmas? Wonder why you feel compelled to eat half a box of chocolates half an hour after finishing your second plate of turkey, dressing, mashed potatoes and gravy? Feel a little guilty?
Well, new research offers clues to one of the most baffling aspects of the eternal battle of the bulge: why we keep eating even when we’re full.
Short version: blame your brain.
When you’re hungry, food looks more appealing than when you’re not: hence the old adage about never shopping on an empty stomach.
Previous research has suggested that ghrelin, a hormone the body produces when it’s short of calories, may act on the brain to trigger this behavior. Now new research suggests that this ...

[podcast]http://edwardwillett.com/wp-content/upLoads//2009/12/Twas-the-Nocturnal-Time.mp3[/podcast]
With apologies to Clement Clarke Moore
’Twas the nocturnal time of the preceding day
To the day we call Christmas (which is, by the way,
Just a modern twist on the eons-old fight
To use feast and fire to end winter’s night).
And all through our dwelling (a.k.a. the house),
Not a creature was stirring, not even a mouse.
(Mus musculus—really a terrible pest,
But even a pest needs a bit of a rest.)
The stockings were hung by the chimney with care,
In hopes that Saint Nicholas soon would be there
(Though that old-fashioned chimney’s so energy-poor
That next year I’m making him use the front door!).
Our genetic descendants lay snug in their beds,
While sucrose-based snack foods danced jigs in their heads,
And mamma in her kerchief, and I in my cap,
Had ...

[podcast]http://edwardwillett.com/wp-content/upLoads//2009/12/Pizza-Slicing.mp3[/podcast]
It’s almost Christmas, and Christmas means food: turkey, dressing, candy canes, oranges, cranberries, chocolate, and, of course, pizza.
(OK, maybe pizza is not the most traditional of foods, but it’s still a popular holiday choice, so humor me.)
Pizzas normally come pre-sliced. The question is, and I’m sure you’ve asked yourself this a lot, “How do we eat this pre-sliced pizza in a way that ensures nobody gets an unfair share?”
That’s the question,
as New Scientist reported on December 11, that Rick Mabry and Paul Deiermann kept asking themselves when they used to share pizza for lunch at Louisiana State University in Shreveport. They kept getting into discussions about the mathematics of slicing it up while ...
