More on teaching creationism

One durable theory of human origins
  • One durable theory of human origins
Looking over the comments that follow my Monday Bleader post on the teaching of evolution and creationism in Tennessee, I see some readers objecting to the idea that creationism be taught as a science.

I hope the earlier post isn't giving the impression that I think it should be. What I wrote, putting my thoughts into the mouth of the governor of Tennessee, was, "I want every graduate of the public schools of Tennessee to understand the theory of evolution and why people believe in it and the theory of creationism and why people believe in it. Science and faith are the twin foundations of America and our kids deserve to be as thoroughly grounded in both as their country is."

In other words, if science and faith can give such extremely different answers to fundamental questions, we cheat children if we don't explain to them the wellsprings of those answers. I doubt if my last post would have occurred to me if I hadn't just read a review of the new book When God Talks Back: Understanding the American Evangelical Relationship With God, by T.M. Luhrmann, a psychological anthropologist.

Considering the caveman Hendrix

Posted by Miles Raymer on 04.24.12 at 02:54 PM

I spend most of my time geeking out over music, but there are a number of other subjects that I like to geek out over as well. One particular favorite is human prehistory, which I find endlessly fascinating. So hearing that the Atlantic was hosting a debate between two scientists (NYU professor of psychology Gary Marcus and University of New Mexico professor of psychology Geoffrey Miller, both of whom have written books on human evolution) on the evolutionary origins of music, I experienced what is known in the scientific community as a "nerd boner."

Is music just a byproduct of human culture? Or is it more innate, possibly even genetic? That's the foundation of Marcus and Miller's discussion, and over the course of it they bring up a number of fascinating subtopics, like singing Neanderthals and the possibility that "rock star" isn't simply a Western cultural construct but an evolutionary tactic with roots going back to the earliest days of human existence. So much nerd boner material.

David Brooks and homicidal fantasies

Should a journalist who cites scientific research to make a point check the validity of the research?

"When somebody who seems mostly good does something completely awful, we’re rendered mute or confused," David Brooks wrote in the New York Times last month. "But of course it happens all the time. That’s because even people who contain reservoirs of compassion and neighborliness also possess a latent potential to commit murder. . . . We're natural-born killers."

Brooks was ruminating on the massacre of 16 Afghan civilians in March, allegedly committed by Staff Sgt. Robert Bales. As evidence of our latent murderous potential, the op-ed columnist pointed to the research of evolutionary psychologist David Buss of the University of Texas. Buss "asked his students if they had ever thought seriously about killing someone, and if so, to write out their homicidal fantasies in an essay," Brooks said. "He was astonished to find that 91 percent of the men and 84 percent of the women had detailed, vivid homicidal fantasies."

New Chicago Beer Company moves out of the Plant

The New Chicago Beer Company space last summer

Samuel and Jesse Edwin Evans, the brothers behind the nascent New Chicago Beer Company, are moving out of the Back of the Yards eco-compound known as the Plant, where they’d been planning since early last year to start their brewery.

The Evans brothers and their plans were the subject of a story I wrote last summer; they said at the time that they expected to open in March 2012 and anticipated producing 12,000 barrels of beer in their brewery's first year. They also said their brew would eventually be available in a 2,500-square-foot tasting room that they were planning.

Breaking ambergris news

Posted by Julia Thiel on 04.09.12 at 12:48 PM

Thar be treasure here?
  • Thar be treasure here?
The Atlantic reports that researchers at the University of British Columbia have discovered a plant-based substitute for ambergris, the waxy whale waste matter that Charles Joly of the Drawing Room was recently challenged to use in Key Ingredient. It's produced in the digestive tracts of sperm whales after the whales consume sharp objects, particularly squid beaks, and then expelled—as Joly so delicately put it—from either end. That's partly conjecture, though: Scientific American reports that scientists, never having seen a whale actually vomit up ambergris, now believe that it's excreted along with fecal matter.
No one has ever seen a sperm whale excrete ambergris, although sperm whale expert Hal Whitehead of Dalhousie University in Halifax, Nova Scotia, admits that it is assumed the voiding takes place as fecal excretion, because when first cast out, he says, "Well, it smells more like the back end than the front."

Retweet it, only louder

For the Bleader's Silence vs. Noise theme last week, I wrote about the minor phenomenon of late-night/early-morning bird chirping—a result of the same urban light pollution that helps guide home the drunks falling out of 4 AM bars the city wide. Of course, the nocturnal glow of street lamps isn't the only distraction to a songbird's mating and defense routines.

According to a recent study conducted in the Presidio district of San Francisco, sparrows have been forced over 35-some-odd years to raise their voices in order to compete with the city's escalating clamor. Researchers David Luther of George Mason and Elizabeth Derryberry of Louisiana State studied the reaction songbirds had to calls recorded in the park in 1969 and in 2005. Guess what happened?

No pun left behind

Brain cells firing in the insular buttock during punning

  • Brain cells firing in the insular buttock during punning
Puns, I realize, aren't everyone's cup of tease. What's brilliant to one person is moronic to another. There's likely a wider gap between pun lovers and pun haters than between Democrats and Republicans. In a referendum on puns, voters definitely wouldn't see aye to aye.

I myself am of the punning perversion. So I agree with the poet Ernest Hartsock, who once wrote that puns "are mainly objected to by Puritans" and that great literature "must arise from a healthy and daring experimentation with words"—an experimentation epitomized by punning. "I have a suspicion that a reason for the disdain of some of our pedants toward puns is a natural inability to grasp wit of any kind," Hartsock said, "—yea, to grasp anything except an air of dignity."

Hartsock's essay, "In Defense of Punning," was published in the linguistic journal American Speech. "The stigma of the pun has been long enough with us," he observed. And he wrote this in 1929.

3 AM tweeting, the other kind

Posted by Kevin Warwick on 03.30.12 at 06:59 AM

Late-night bars are the devil's work, and Chicago has too many of them. As the clock creeps closer to dawn, bad decisions begin dressing up all dapper like and convincing drunkards that, yes, another shot and grabbing a frozen pizza on the way home is the way to go. The formerly spry, wide-eyed me used to be the first to suggest a 4 AM den of iniquity—one ready and willing to expedite crippling hangovers—when the night needed a pick-me-up. Now, I just can't hack it.

And that's OK, because in addition to having a delicate 30-year-old body actually complete menial weekend tasks, I'm also able to avoid the eerie, discombobulating early morning chorus of the songbirds. As if having the bar lights dialed up to tanning-bed-level brightness isn't sobering enough, stumbling out the front door into 4:30 AM Chicago and hearing bird chirps bounce around alleyways and off apartment buildings is a dizzying kind of surreal.

Whale vomit in history

Posted by Julia Thiel on 03.22.12 at 07:06 AM

ambergris.jpg
  • Peter Kaminski
For this week's Key Ingredient, mixologist Charles Joly of the Drawing Room faced off against ambergris—the aromatic, waxy substance produced in the digestive tract of sperm whales and historically used for perfume, among other things. I'd never heard of it before, which my coworkers pointed out was probably because I'd never made it through Moby-Dick in my freshman-year literature class. There's an entire chapter devoted to the stuff, immediately following the one in which the whalers come across a French ship that has claimed two pungent whale carcasses; Stubb tricks the Frenchmen into surrendering one that he hopes will yield ambergris (it was valuable back then, too, "worth a gold guinea an ounce to any druggist"). He's rewarded with "some six handfulls."

A sight for sore ears

Posted by Miles Raymer on 03.19.12 at 05:30 PM

Ear-anatomy-notext-small.png
Good news for those who suffer from tinnitus (a common side effect of hearing damage), as well as for music lovers who depend on their ears for their livelihood and anyone else who asks a lot of their auditory system: very early tests out of the Tinnitus Clinic in London indicate that researchers may have found a cure for the condition, which has long been considered incurable. What's even more remarkable is that the therapy doesn't involve surgery or drugs or anything more invasive than wearing headphones playing a "series of tones tuned according to the characteristic frequency of the patient's tinnitus," which "'reset' auditory nerve cells in the brain to stop them misfiring," according to the Independent. And unlike past treatments, this one seems to actually remove the constant ringing that tinnitus sufferers hear, rather than teaching them to ignore it. So far it's only been tested on 63 subjects—though 2,000 or so have had this "Acoustic CR Neuromodulation" in Germany—but it's worked on 75 percent of them, and the results look to be long-lasting.
