Drug-Resistant E. Coli Rampant Among Poultry Workers

| Mon Dec. 17, 2007 5:02 PM EST

If you needed yet another reason to be grossed out by the American meat industry, consider this tantalizing tidbit: U.S. Poultry workers are much more likely than the average American—32 times more likely, in fact—to carry antibiotic-resistant E. coli bacteria, according to a Johns Hopkins study.

With the recent news that drug-resistant staph infections are on the rise, most people I know have become vigilant about germs in public places. Flip-flop use in gym locker rooms, I'd bet, is on the rise. But actually, we should be feeling squeamish about big ag: "One of the major implications of this study is to underscore the importance of the non-hospital environment in the origin of drug resistant infections," says Eileen K. Silbergeld, one of the study's lead authors, in the study press release. Growth-stimulating antibiotics are just another part of the daily grind (ugh, sorry) at mega-farms. In fact, it's thought that the majority of antimicrobials produced in the U.S. are used in the meat industry. And unfortunately, unlike at the gym, flip-flops probably don't offer much in the way of protection at the slaughterhouse.

This Is Your Brain on Music

| Tue Dec. 11, 2007 4:00 PM EST

brain%20200.jpgFor the past few years, I've been posing a question to all my music-enthusiast friends: Why do we like music? And more specifically, why do we like the particular music that we do? "There's no accounting for taste" simply doesn't cut it for me. I'd like someone to explain to me exactly what accounts for musical taste. So far, though, no one's been able to answer my question definitively.

All this has, however, led to some pretty interesting nature-vs.-nurture discussions. Most people I've asked are cheering for nurture. "My older brother was really into hardcore, and I ended up stealing all his mixtapes," they'll say. Or, "I liked this guy in high school who played in a punk band." Even, "I used to dance around my living room to my parents' Paul Simon tapes, so I've always had a soft spot for folk music."

So it's pretty clear that formative musical experiences influence our music preferences at least a little, but there's some scientific evidence that there's an organic component, too. Today, I came across an Innovation Canada interview with Daniel Levitin, a McGill University neuroscience professor who studies music's effect on our brains. Now don't get your hopes up: Levitin says that scientists have a long way to go before they'll be able to answer the taste question. But what's really interesting is Levitin's unique research method:

IC: You emphasize using actual music — not abstract electronic sounds — in your studies. Is rap music by Busta Rhymes better than classical Bach for your research purposes?
DL: Part of the challenge in designing a rigorous experiment is ensuring that each subject has something equivalent. In the old way of thinking, you played everybody the same piece of music, but if you hate classical music and I make you sit for an hour and answer difficult questions about music while listening to Beethoven, I may not be getting meaningful answers out of the experiment. The newer way of thinking is that we need to be flexible about equivalence across subjects. That doesn't mean a loss of rigour, it means that you might have an experiment where everyone brings in their own music and each subject serves as their own control. So, the experiment may steer more to [rapper] Ludacris than [virtuoso pianist/composer] Liszt depending on who your subject is.

So even if he can't explain taste, Levitin is obviously acknowledging that it exists—and that it's important. My challenge to Levitin: Find me a scientific explanation for the fact that anyone was ever into the Doors. Now that would be impressive.

Divorce is Bad for the Planet

| Tue Dec. 4, 2007 2:44 PM EST

"Oh, I wish that we could stop this D-I-V-O-R-C-E." Mother Nature probably agrees with Tammy Wynette. According to a recent Michigan State University study, divorce is taking a major toll on the environment.

Some of the findings:

* In the United States alone in 2005, divorced households used 73 billion kilowatt-hours of electricity and 627 billion gallons of water that could have been saved had household size remained the same as that of married households. Thirty-eight million extra rooms were needed with associated costs for heating and lighting.

* In the United States and 11 other countries such as Brazil, Costa Rica, Ecuador, Greece, Mexico and South Africa between 1998 and 2002, if divorced households had combined to have the same average household size as married households, there could have been 7.4 million fewer households in these countries.

* The numbers of divorced households in these countries ranged from 40,000 in Costa Rica to almost 16 million in the United States around 2000.

* The number of rooms per person in divorced households was 33 percent to 95 percent greater than in married households.

But the researchers also point out that divorce is just part of the picture: In the U.S., multigenerational households have become less common over the past few decades. What's more, single people are putting off getting married, and hence living alone for longer. Seems like the only bright side about sky-high rent, then, is that it might actually make some cities greener (since fewer people can afford to live alone).

Creationism Kerfuffle Forces Texas Science Curriculum Head to Resign

| Fri Nov. 30, 2007 3:15 PM EST

Texas' director of science curriculum has been forced to resign over an e-mail she sent. What was in the offending message ? Trash talk about colleagues? Porn? Nope—it was about (drumroll, please) an upcoming lecture. The horror! Read more on the Blue Marble.

Texas Science Curriculum Director Resigns Over Creationism Kerfuffle

| Fri Nov. 30, 2007 2:29 PM EST

creation190.jpgThe science blogosphere is abuzz (here, here and here, for starters) with some juicy creationism news from Texas. According to the Austin American-Statesman, Chris Comer, the state's director of science curriculum, was pressured into resigning this month. Her crime? Forwarding an e-mail about an upcoming talk by creationism expert Barbara Forrest. (Now mind you, by "creationism expert," I don't mean "creationist." Barbara Forrest testified in the Dover trial, and according to Pharyngula blogger PZ Meyers, she had creationists shaking in their boots.)

Anyway, long story short, the Texas Education Agency (TEA) had a fit. A TEA memo obtained by the Statesman said, "Ms. Comer's e-mail implies endorsement of the speaker and implies that TEA endorses the speaker's position on a subject on which the agency must remain neutral."

Now, never mind the fact that the neutrality for which Texas strives on the subject of creationism pretty much amounts to bad science. Even if neutrality is your goal—heck, even if you're the biggest creationist ever—you might still be interested in hearing what this Barbara Forrest has to say. And if you're a teacher, you're ostensibly interested in open forums, free exchange of ideas, etc. Tough luck for you if you're teaching in Texas. Talk about a hostile learning environment.
