Invasive crazy ants have a taste for technology

It sounds like an old black-and-white monster movie. Crazy, tech-nesting ants invade America! That would make for a great matinee, but it's oh so very real. Tawny crazy ants, known scientifically as Nylanderia fulva, are marching into territories once dominated by fire ants -- and they're not being very good neighbors.

While fire ants have made their sting notorious, tawny crazy ants have a propensity to infiltrate unwelcome places en masse. They're making fire ants look positively polite. The South American native ants are attracted to electronics in particular. Once inside, they create short circuits, says University of Texas research assistant Edward LeBrun.

"When they get electrocuted, they release an alarm pheromone," he says, adding that this attracts more ants and exacerbates the problem.… Read more

Tesla hits first profitable quarter ever

In his quarterly earnings letter to shareholders on Wednesday, Tesla CEO Elon Musk announced that "Tesla reached profitability in the first quarter of 2013 for the first time in our 10-year history."

Tesla eyes 'autopilot' partnership with Google

Tesla, the electric car maker, has been in talks with Google about the development of a self-driving car, the former's CEO revealed Tuesday.

In a Bloomberg interview, Tesla CEO Elon Musk said that his company has "had some technical discussions with Google" about the search giant's self-driving car technology.

Instead, Musk told Bloomberg, he'd like to see a camera-based system that "sees" what's … Read more

Tesla announced today that it would offer its high-end Model S Performance edition, with an 85 kilowatt-hour battery pack, and the Roadster as loaner cars for when owners' cars are being serviced.
