sciencehabit writes "To find out if certain dance moves are more attractive to women than others, researchers recruited a bunch of college guys and used motion-capture to create avatars of them dancing. When women watched the avatars (2 videos included in story), the men they found most attractive were those who kept their heads and torsos moving without flailing their arms and legs. The researchers say dancing is thus an honest signal to women of the man's strength and health, just as it is in crabs and hummingbirds, who also move in special ways to attract mates."

Whether they spoil in the heat, freeze in the winter, or get taken out by a human-friendly venue of vultures, a zombie outbreak is unlikely to succeed. Here's 7 reasons why we should stop worrying about the shambling dead and start concentrating on a real threat: sparkly vampires.

thecarchik writes with this snippet from GreenCarReports: "One of the criticisms of hybrid cars has historically been that there's no payback, especially given the cheap gasoline prices in the US. The extra money you spend on a hybrid isn't returned in gas savings, say critics. Well, that may be true, especially when regular gasoline is averaging $2.77 a gallon this week. But as we often point out, most people don't buy hybrids for payback — they buy them to make a statement about wanting to drive green. Nevertheless, a Canadian study has now looked at the question of hybrid payback in a country whose gasoline is more expensive than ours (roughly $3.70 per gallon this week), with surprising results. The British Columbia Automobile Association projected the fuel costs of 16 hybrids over five years against their purchase price and financing fees. In a study released in late July, only a single one of the 16 hybrids cost less to buy and run than its gasoline counterpart." The one car that would save you money, according the study, is the Mercedes S400 Hybrid sedan — and it will only cost you $105,000.

A few years ago we reported that it had been proven that Rubik's Cubes could be solved in 23 moves. Well now that number is down to just 20. Proving it required 35 years of computer time donated by Google to get it done.

An anonymous reader writes "Tesla, which will trade under TSLA on Nasdaq, has been priced at $17 per share, allowing the electric car start-up to raise more than $226 million in its IPO. Investors were expecting the share price target range to be between $14 and $16 but the overflow of excitement saw Tesla increase the number of shares it plans to offer to 13.3 million, nearly 20 percent more than originally planned." Reader hlovy contributes a link from Xconomy.com summarizing the skepticism among some analysts as to how much staying power TSLA will demonstrate.

ElectricSteve writes with this excerpt from Gizmag: "Ready for a bit of a mental mechanical challenge? Try your hand at understanding how the D-Drive works. Steve Durnin's ingenious new gearbox design is infinitely variable — that is, with your motor running at a constant speed, the D-Drive transmission can smoothly transition from top gear all the way through neutral and into reverse. It doesn't need a clutch, it doesn't use any friction drive components, and the power is always transmitted through strong, reliable gear teeth. In fact, it's a potential revolution in transmission technology."

Hugh Pickens writes "The San Francisco Chronicle reports that Google has released Jarlsberg, a 'small, cheesy' web application specifically designed to be full of bugs and security flaws as a security tutorial for coders, and encourages programmers to try their hands at exploiting weaknesses in Jarlsberg as a way of teaching them how to avoid similar vulnerabilities in their own code. Jarlsberg has multiple security bugs ranging from cross-site scripting and cross-site request forgery, to information disclosure, denial of service, and remote code execution. The codelab is organized by types of vulnerabilities." (Read on for more.)

An anonymous reader writes "In an unfortunate data breach, social media site Blippy has left credit card numbers in clear text, searchable via a simple Google query. The results show the amount spent on a transaction, the location, and the full card number. As of this submission, the issue still hasn't been resolved." The company's co-founder, Philip Kaplan, told the NY Times, "... when people link their credit cards to Blippy, merchants pass along their raw transaction data – including some credit card numbers – and the site scrubs that information to present just the merchant and the dollar amount spent. But several months ago, when Blippy was being publicly tested, that raw transaction data was present in the site's HTML code, where it was retrieved by Google. Mr. Kaplan said that early on, Blippy started disguising the raw transaction data behind the scenes, but it did not know about the breach until today."

TheOtherChimeraTwin notes that the shuttle Discovery will land at Kennedy Space Center on Monday morning at 8:48 EDT. The craft will make a rare "descending node" overflight of the continental US en route to landing in Florida. Here are maps of the shuttle's path if is lands on orbit 222 as planned, or on the next orbit. Spaceweather.com says: "...it takes the shuttle about 35 minutes to traverse the path shown... Observers in the northwestern USA will see the shuttle shortly after 5 am PDT blazing like a meteoric fireball through the dawn sky. As Discovery makes its way east, it will enter daylight and fade into the bright blue background. If you can't see the shuttle, however, you might be able to hear it. The shuttle produces a sonic double-boom that reaches the ground about a minute and a half after passing overhead."
