Bike seats may contribute to erectile dysfunction -- and it's no surprise, when you consider where you shove 'em. “When you sit on a regular bike saddle, you’re sitting on your penis,” says reproductive physiologist Steven Schrader. If that didn't just make you cross your legs, don't get comfortable, ladies: More than 60 percent of you will experience genital pain, numbness, or tingling from sitting on a bike seat. According to this New York Times article, at least, bike seats are the worst threat to your junk since America's Funniest Home Videos. Regular bike saddles put pressure on your perineum …

Get off your high horse, New Yorkers! City dwellers might do some environmental good by driving less and living in smaller spaces. But living in a city doesn't affect a person's carbon footprint as much as the amount that he or she buys. It's simple: living in a city is just another consumption decision. City dwellers consume less, generally, when it comes to things like daily transportation and home climate control. But if they splash out on other things -- clothes, plane trips, expensive sushi -- they can easily cancel out the dent their location puts in their carbon footprint. …

Some flights out of JFK International Airport were delayed today as officials scrambled to clear runways of turtles. Apparently the diamondback terrapins, which live in nearby Jamaica Bay, were all "oh yeah, buiding a runway next to our habitat? That's how you're gonna play it? Fine, WE F*CK ON YOUR RUNWAY. DEAL WITH IT." Still, if there's a cuter reason to get stuck in the airport than turtles putting baby turtles inside other turtles, we don't know about it. This is not even the first time that the JFK runways have been the site of a chelonian sex-fest. In 2009, …

Madagascar's tortoises are being wiped out by a "tortoise mafia" that authorities are powerless to stop. One reason: their shells are prized as an aphrodisiac in some parts of Asia. You might ask, "well, what hasn't been touted as the hidden folk-medical secret to letting old men impregnate everything in a five-mile radius?" The answer is: hardly anything. Here are four more animals endangered by the myth that some part of their bodies contains the secret to irresistible tumescence:  Tigers and their penises Is this a tiger penis being smuggled into New Zealand? You be the judge. All five remaining subspecies …

Google set out to discover the effects of technological breakthroughs, and in the process discovered that strong government policies are key to accelerating their penetration into the market. Radical new battery technology and solar panels are great, but regular consumers don’t pick them up unless they're nudged in the right direction. In other words, the internet’s most successful capitalists say that the free market is all well and good, but we really need government regulation. Here are some other things Google discovered in their analysis of cleantech breakthroughs: 1. By 2030, electric cars will have the most profound impact of …

Hey, remember Tim Pawlenty? I think he's running for state auditor or something. Pawlenty used to think climate change was a major priority, back when he was governor of Minnesota and supported cap-and-trade. But then Mitt Romney and Jon Huntsman showed underbelly by admitting that they believe in science -- a striking liability in this race -- and Pawlenty took that opportunity to swoop in and firmly establish himself as the most anti-climate-science candidate besides Bachmann and Perry and all the other ones! Go get 'em, T-Paw. Here's Pawlenty's attempt at ginning up some Bachmann-style crazy: "So there is climate …

Germany, Korea, China, and now India are all venues for U.S. carmaking giant General Motors’ new all-electric hotness, the Chevrolet Beat. The Beat sounds like exactly the thing to revive the flagging fortunes of G.M., bringing it into a 20th century in which soaring gas prices and ever-cheaper battery technology push consumers into the arms of the Nissan Leaf and the forthcoming Ford electric vehicles. Except G.M. has no plans to release the Beat in the U.S., much less its electrified version. Maybe once your CEO has gone on record saying that global warming is a crock of sh*t, you …

In the patriarchy (that's Women's Studies for "dicktopia") we live in, there is pretty much no worse fate than wussification. So in a way, we're glad to hear that Bisphenol A, an organic compound found in a lot of plastics, makes male mice act less masculine. Maybe this will induce Girl Panic in some of the straight dudes who run things, and we can finally get the stuff taken out of our baby bottles, plastic packaging, and cans.  According to an article published in the Proceedings of the National Academy of Science, deer mice exposed to BPA in utero (the …

In case you hadn’t heard … the world is warming up. Exxon just can't quit climate deniers. The Supreme Court thinks that the EPA must regulate carbon under the Clean Air Act; now it will decide if it can regulate wetlands on private property under the Clean Water Act. Gas stations can now sell a 15 percent ethanol blend. If you drive an old clunker, stay away from the E15 -- it'll screw your engine up. The Sierra Club has to sit back and let the U.S. government take BP to court for the Macondo spill. The Railroad Park in …

Did you get a flat, forget your snacks, or break a light while tooling down the Greenway in bike-friendly Minneapolis? No worries -- just stop by the Bike Fixtation, a one-stop bike-shopping outpost. You can buy a patch kit or some trail mix from the vending machine, pump up your tires with the air pump, and do minor repairs on the work stand.  Right now Bike Fixtation is a real small operation -- under "About Us" on the website, it says the "owned and operated by Brad and Alex." There are only two locations, one open and one forthcoming, both in …
