Why sunlight in your eyes can make you sneeze

[podcast]http://edwardwillett.com/wp-content/upLoads//2009/04/photic-sneezing.mp3[/podcast] “Sunshine on my shoulders makes me happy,” the late John Denver sang. “Sunlight in my eyes can make me cry.” Lovely lyrics. But as a kid, I thought it would have made more sense for Denver to sing, “Sunlight in my eyes can make me sneeze.” Because for somewhere between one in 10 and one in three people, sunlight has exactly that effect. It’s called “photic sneezing,” and it’s nothing new: Aristotle wondered about it in the 4th century BC (although he thought it was brought on by heat, not light). But millennia later, we still don’t know exactly why it happens, as New Scientist writer Richard Webb recently discovered. The usual explanation for regular sneezing is that it serves to ...

Science shows musicians really ARE more sensitive

[podcast]http://edwardwillett.com/wp-content/uploads/2009/04/sensitive-musicians.mp3[/podcast] Musicians have a reputation for being sensitive types, finely tuned to the emotions of those around them. In fact, it’s become a bit of a cliché in movies (with the possible exception of the many late drummers of Spinal Tap). Normally, after a beginning like that, I’d go on to write that science has now proven the cliché wrong--but in this case, quite the opposite is true. Researchers at Northwestern University have found that the more years of musical experience musicians possess, and the earlier the age at which they began studying music, the better their nervous systems are at interpreting the emotional content of sound. The study was led by doctoral student Dana Strait, who conducts her research in the Auditory Neuroscience ...

The fad cycle

Here’s a fearless prediction for 2009: sometime, somewhere, something is going to become a hot new fad.It’s a cycle as old as...well, as old as me, anyway, and I suspect a good deal older. Since I was a teenager in the 1970s, I think in terms of Rubik Cubes, platform shoes, bell-bottoms and mood rings.Today I’m so far out of it, pop-culture wise, I’d hesitate to even mention a 2008 fad for fear it’s already last-year’s thing. (Although, since this column appears on New Year’s Eve, I guess you could say any 2008 fad is last-year’s thing.)Perhaps you have fallen for a fad yourself, once in a while. I would say that I never ...

I have a dream…wanna see it?

“I’m dreaming of a White Christmas,” singers warble this time of year. Up until now, we’ve had to take their word for it.But what if there were technology that could actually record imagery from a dream, and play it back for everyone to see?Hang onto your nightcaps, because it may be on its way.A team at ATR Computational Neuroscience Laboratories in Kyoto, Japan, led by Yukiyasu Kamitani, reported last week that it has successfully scanned the brains of human subjects and recreated, from scratch, images they were observing at the time.They weren’t very exciting images: crude, black-and-white shapes, numbers, and the word “neuron,” but the fact they were able to pluck them ...

Books, movies, reality are all equally disgusting–and that’s a good thing!

I write nonfiction (obviously), but I also write science fiction and fantasy.We who write such stuff are occasionally asked (and occasionally wonder) if our works can continue to compete in a media universe in which “science fiction” and “fantasy” conjure up for most people Hollywood special-effects extravaganzas first, and the written word second (if at all).I was therefore heartened to read of a recent scientific study that indicates that books are every bit as good at stirring emotions as movies.(Alas, the particular emotion being studied was disgust, which is one most writers--Stephen King perhaps being the exception--only occasionally wish to invoke for fear the disgust will spill over from specific scenes to the entire ...

Good news for live musicians

Neuroscientists have found that a piano sonata played by a human being elicits stronger emotional responses than the same piece played by a computer:Senior research fellow in psychology [at the University of Susses] Dr Stefan Koelsch, who carried out the study with colleagues at the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, played excerpts from classical piano sonatas to twenty non-musicians and recorded electric brain responses and skin conductance responses (which vary with sweat production as a result of an emotional response). Although the participants did not play instruments and considered themselves unmusical, their brains showed clear electric activity in response to musical changes (unexpected chords and changes in tonal key), ...

Monday, Monday

From the Mamas and the Papas’ “Monday, Monday” to the Carpenters’ “Rainy Days and Mondays” to the Boomtown Rats’ supremely creepy “I Don’t Like Mondays,” the first day of the work and school week has been vilified as a day of depression.But new research shows that people’s moods don’t really change that much over the course of a week: people are not, in fact, noticeably happier on Friday evenings and Saturday mornings than they are on Mondays.Yet they both expect to be, and believe they were, and so the myth persists.That’s according to Charles Areni, a marketing professor at the University of Sidney in Australia, in a paper published in the Journal of ...

This is your brain on Hitchcock

Alfred Hitchcock, James Vermiere wrote in the Boston Herald on the occasion of the centenary of Hitchcock’s birth in 1999, “delighted in terrifying audiences by manipulating them...More than any other filmmaker, he was a master at messing with our minds.”“Wait a minute!” I hear you cry (if I happen to be sitting behind you as you read this, creeping up on you, breathing down your neck, about to...Ha! Made you look!). “What does all this stuff about Hitchcock, and your rather lame attempt to capture some of the Hitchcockian spirit in the first half of this paragraph, have to do with science? Have I stumbled upon a new film criticism column by mistake?”Nay, dear reader. I ...

Try to remember

Ever try to list a series of interesting things you've heard or own or read about for someone else, only to end up saying something like, "and...and...and I forget the other thing."There's a good reason why we often "forget the other thing"--because our conscious mind, or what is sometimes called our "working memory," has a limited capacity.Just how limited has become clearer with new research published recently in the Proceedings of the National Academy of Sciences, described in a story by Clara Moskowitz at LiveScience.com.How many things can you hold in your working memory? According to this new research, probably no more than three or four.That's lower than the previous estimate of ...

Sleep in a bottle

I love a good night’s sleep. I just rarely get one that’s quite as long as I’d like.I’m not alone in that, either. Although exactly how much sleep any individual needs varies according to that individual’s age, sex, genetic makeup and other factors, studies indicate that the “normal” sleep need for most adults is between seven and eight hours a night (teenagers need more like nine, and preschoolers 11 to 13, and schoolchildren up to age 12 need 10 to 11).According to Statistics Canada, in 1998, men averaged 8 hours of sleep a night and women 8.2, which sounds pretty good: however, 17 percent of men and 13 percent of women reported sleeping less than 6.5 ...
