"Science" news and stories

A chilled Martini is truly a work of art. But the chemist/photographers behind the company BevShots have taken that idea to the microscopic level. Research scientist Michael Davis, of Florida State University, crystallizes cocktails on a lab slide, then photographs them using a camera attached to a light microscope. According to Davis, the light is polarized, resulting in these wild images of, say, a Tequila Sunrise or a Margarita. Oh, and you can buy the photos to memorialize cocktail hour 24-7. (Davis also made the images into ties, in case you want to sport your Guinness at the office.)

Hold the spritz of Calvin Klein Obsession, ladies and gentlemen. If you want to arouse your man, get a pumpkin pie baking in the oven. And, no, that is not a metaphor. According to a new study conducted by Chicago's Smell and Taste Treatment Research Center, the smell of pumpkin pie turns men on. Of the 40 scents tested (including strawberry, lavender, and vanilla), the odor of the spiced squash in a crust "increased the men's penile blood flow by an average of 40 percent" by reducing anxiety, and thus eliminating inhibitions.

And get baking! Here's Curtis Stone's recipe for Homemade Pumpkin Pie with Caramelized Walnuts to get the party started.

From the UK comes excellent news for beer drinkers -- and their bellies: According to the results of a new study, beer bellies are caused by genetics, not beer.

After tracking 7,876 men and 12,749 women over the course of eight and a half years, a group of German and Swedish researchers discovered that while regular drinkers -- especially those who consumed the equivalent of two pints a day -- were more likely to gain weight overall, that weight did not necessarily accumulate in the abdominal region. The scientists concluded that while "beer consumption seems to be rather associated with an increase in overall body fatness," evidence of more "site-specific" weight gain was limited. Somewhat unsurprisingly, given its pivotal role in most weighty matters, genetics was the real culprit.

The news couldn't have come at a better time, i.e summer, when hot days call out for cold brews and beer aficionados seek sweet relief in air-conditioned bars across the country. It's possibly the best news since, oh, last week, when New York City declared July Good Beer Month, and will doubtless inspire countless toasts made over frosty mugs held high.

While organic food producers must follow certification standards, fraud is on the rise. After all, organic foods can cost up to two or three times more than conventionally grown products, meaning some unscrupulous producers are bound to be looking to line their pockets.

Now, the New York Times reports that scientists are investigating the feasibility of lab testing organic foods to keep companies honest.

German scientists have found that organic milk has higher levels of a certain fatty acid than regular milk, a result of different cattle feeding practices. Labs can reliably discern which milk is organic by testing for this fatty acid. And we've already seen that it's possible to test for the presence of non-organic, synthetic fertilizers in fruits and vegetables, but the high cost of testing means the practice is unlikely to be implemented on a large scale.

While this is all preliminary stuff, it will be interesting to see whether we eventually find more "organic markers" to test food, and whether buyers will find this worthwhile.

I was always the kind of kid who put stuff in my mouth that didn't belong - wooden stacking blocks, my mom's car keys, the occasional earthworm. I loved the feel of a bit of sand in my sandwich, and I could never keep my teeth off my deliciously grimy fingernails. Now, as an adult, I rarely get sick, despite my predilection for taco trucks, Indian street food and pork products of dubious origin. Is there a connection?

In this week's New York Times health section, Jane Brody writes about what's known as the hygiene hypothesis - the theory that ingesting plenty of bacteria and viruses as a child can help develop a healthy immune system. Though no one disputes that public health measures like sewer systems and food production regulation have improved overall health immeasurably, studies have also shown higher rates of autoimmune disorders, allergies and asthma in people raised in ultra-clean environments. Basically, their systems don't "learn" to deal with foreign bodies, and become ultra-sensitive, attacking even normal tissue. Some research even suggests that deliberately infecting patients with worms can help treat certain auto-immune issues.

While most of us aren't going to go out and deliberately swallow pig whipworms, I think the hygiene hypothesis lends support to the increasingly widespread idea that it's OK to eat foods that fall outside the (supposedly) sterile confines of corporate agriculture. So let's all eat some raw milk cheese, cook some antibiotic-free meat, buy some gnobbly farmers market carrots with clods of earth still clinging to the tops. And maybe a little mud pie for dessert.
