Beetles battle to be the top poopmaster! (Science)

DruhimDruhim Registered User, ClubPA regular
edited April 2010 in Social Entropy++
Yes, female beetles of the species Onthophagus sagittarius have evolved horns so they can fight each other for valuable poop deposits.
Horns on bulls, antlers on stags and other guy weapons have preoccupied scientists who study evolution, Stankowich says. Darwin proposed that male weaponry arose from the struggle between rivals for access to females, and later work has found plenty of examples that fit that scenario.

Yet females of some species grow their own arsenals. Defense against predators probably drove the evolution of female horns in some bovine species, for example, according to work by Stankowich and Tim Caro of the University of California, Davis. In a smaller number of other bovines, such as the little antelopes called duikers, territorial battles probably favored female horns.

But the beetle horns are special, Stankowich says. Female duiker horns generally look like the males’, but female dung beetles grow another type of horn altogether.

The female beetles sprout a large central horn with a smaller stub in front of it, Watson says. The arrangement looks like a miniature version of a rhino’s arsenal. Males grow a pair of stubbier horns, more like a bull’s, that sprouts from a different place on the body.

Because male and female horns are so different, Watson and Simmons dismiss the possibility that the female horns grow simply as some kind of genetic spillover from male horns. Instead, Stankowich says, “it’s an independent evolutionary event from male horn evolution.”

    In Ten Years a Box of Sand Could Power Your House
    USA Today wrote:
    Silicon Valley start-up Bloom Energy is unveiling a fuel-cell product Wednesday that can power a small office building. It expects to have home systems within a decade that are about the size of a loaf of bread, it says.
    Bloom's technology gives users the ability to produce electricity — as opposed to buying it from utilities — and has the potential to extend electricity to parts of the world lacking traditional power systems and lines, Bloom says.

    Bloom Energy, backed by Silicon Valley's leading venture capitalist, has been in stealth mode for eight years. Today, it's scheduled to announce that 20 companies, including Wal-Mart, Google, eBay, FedEx, Staples, Coca-Cola, Bank of America and Cox Enterprises, have bought Bloom's fuel-cell boxes. The commercial-scale boxes are about the size of a parking space and cost $700,000 to $800,000.

    Bloom CEO KR Sridhar expects home models within 10 years that cost less than $3,000. He says consumers could see the so-called Bloom boxes powering apartment buildings and housing developments before that.

    Sridhar, a professor of aerospace engineering who once led a team developing technology to sustain life on Mars for NASA, says utilities could buy the boxes, too, to power neighborhoods.

    With Bloom's fuel cell, air and fuel — such as natural gas, ethanol or biogas — are fed into the cell. The oxygen ions react with the fuel to produce electricity. There's no burning, so the fuel cell is two-thirds cleaner than coal-fired plants, Bloom says.

    Automakers have been working on fuel cells for vehicles for years. A few companies also sell commercial systems. The big challenge is cost.

    FuelCell Energy, a 41-year-old Connecticut firm, shipped its first commercial system in 2003. It still loses money on every unit and has amassed losses of $600 million, says equity analyst Pavel Molchanov of Raymond James & Associates.

    Sridhar says Bloom's technology is cheaper and more efficient than others because of proprietary technology that enables it to use low-cost materials — sand and ink — in 4-inch-by-4-inch fuel cells as thick as business cards. One cell powers a light bulb. Bloom stacks them together to produce more power.

    Bloom's big breakthrough was reducing breakage by figuring out how to get the cells and the metal plates that go between them in the stacks to expand and shrink at the same rate at temperatures up to 800 degrees Celsius (1,472 degrees Fahrenheit). The high heat makes the fuel more reactive and the cell more efficient, Sridhar says. The heat also enables use of different fuels, making the tech easier and cheaper to deploy, he says.

    EBay started using five Bloom boxes in July. They produce electricity to power space for 2,000 to 3,000 employees and shaved $100,000 off eBay's power bill, says Amy Skoczlas Cole, director of eBay's Green Team. EBay uses natural gas in the boxes but will switch to methane gas from an Oklahoma landfill this spring.

    Bank of America plans to use Bloom boxes to power a California call center. Coca-Cola is deploying Bloom boxes at a plant in California. They're expected to provide 30% of the plant's power while reducing its carbon footprint by 35%, a Bloom press release says.

    EBay's Cole expects Bloom boxes to pay for themselves within three years, given a 30% federal tax credit and a 20% subsidy from the state of California. "In a few years, we won't require subsidies to become the most affordable energy," Sridhar says.

    Bloom's lead venture-capital backer, John Doerr, who also helped fund Netscape and Google, says Bloom's technology won't solve the USA's clean-energy needs. "It's not a silver bullet," he says, but a piece of an emerging clean-energy economy. "Everybody wants clean, reliable, affordable electricity," Doerr says.

    New gadget eliminates pain in dental injections
    People of the world who hate hate HATE going to the dentist, rejoice: DentalVibe is a new device that completely eliminates the pain when they are sticking a stainless steel needle into your gums. All by cleverly fooling your brain.

    Developed by Dr. Steven G. Goldberg DDS and Bresslergroup, DentalVibe vibrates at irregular intervals. While the brain ignores rapid rhythmical vibration, it notices pulses that are not regular. These vibrations are transmitted by A-beta nerve fibers, which are faster than the slower C fibers that transmit the sensation of pain caused by the needle penetrating your gums.

    The result is that your brain will only notice the percussive vibration, but not the pain of the needle tearing apart the flesh of your gums until it hits the bone. Clever. Now they only have to solve the problem of the drilling, the tubes stretching your mouth, and the muzzak making you brain melt.
