BY STEVEN SPARKMAN ANCHOR ANA COMPAIN-ROMERO You're watching multisource tech news analysis from Newsy Tired of plugging in your mobile devices? Try charging them while you walk. Scientists from Georgia Tech have created what they call the first commercially viable nanogenerator. It’s a chip that uses your body as a power source. Metro explains how it works. “Hailed as a milestone, the tiny chip works by using zinc oxide nanowires so small that 500 could fit in a human hair. When they are strained or flexed, electricity is produced -- meaning any body movement from the pinch of a finger to a beating heart can generate power.” The researchers say this is the first of these generators that can deliver a high enough charge to power electronics. Lead researcher Z.L. Wang demonstrated to the American Chemical Society how the device produces as much electricity as a pair of AA batteries. “The major breakthrough we have made in last year is to boost up the power output. … So that means we have ten microwatts of energy output. How do we do this? It’s just any mechanical flicking like this. There’s two volts come off that.” The technology is so adaptable, it can be used practically anywhere. Wang said they’ve already experimented with lining a car tire with the devices. But Geek**** explains the use that’s getting tech addicts really excited: no more plugging in. “In principal, the nanowires are small enough to sew or embed into pretty much everything. … So if they were embedded in your pants, every step you take would generate a charge of electricity that could be funneled into an iPod or a battery pack… Pretty neat, huh? We’ll all be walking portable gadget chargers before we even know it.” If that’s not sci-fi enough for you, there’s even talk of using the human heartbeat to generate power. Tech bloggers are dreaming of heart-powered phones, but a writer for Register Hardware says it’s probably premature to line up for the iPulse. “Of course, actually implementing these devices as coronary iPod chargers isn't a top priority, but Wang's idea of a heart powered nano chip to run an implanted insulin pump is a more serious suggestion likely to get medical attention.” Wang says he hopes to bring the chips to the market in three to five years, ready to be put into shoes, tires, train tracks...

DAVET Dörtnala gelip Uzak Asya'dan Akdeniz'e bir kısrak başı gibi uzanan bu memleket bizim. Bilekler kan içinde, dişler kenetli, ayaklar çıplak ve ipek bir halıya benziyen toprak, bu cehennem, bu cennet bizim. Kapansın el kapıları, bir daha açılmasın, yok edin insanın insana kulluğunu, bu dâvet bizim... Yaşamak bir ağaç gibi tek ve hür ve bir orman gibi kardeşçesine, bu hasret bizim...

Kaikki American Pie -komedioista tutut hahmot tekevät paluun uudessa elokuvassa American Pie: Luokkakokous! Kuka saikaan kenet, janottaako vanha suola, ovatko luokkakokoukset yhtä kosteita kuin kouluaikojen bileet – ja onko Stiflerin äiti edelleen MILF? On tullut aika kerätä jengi kasaan, kaivella vanhoja ja keksiä uusia kujeita. Kymmenen vuotta sitten neljä kundia löi vetoa päästäkseen eroon poikuudestaan lukukauden loppuun mennessä. Nyt Jim ja Michelle ovat menneet naimisiin ja saaneet lapsen, Kevin ja Vicky eronneet ja Oz ja Heather kasvaneet erilleen – mutta Finch haikailee edelleen Stiflerin äidin perään. Koko joukko palaa kotikaupunkiinsa luokkakokoukseen verestämään nuoruusmuistoja. Yllätyksiä täynnä olevan viikonlopun aikana he näkevät mikä on muuttunut ja mikä pysynyt ennallaan. American Pie -elokuvasta tuttu näyttelijäkaarti, mm. Jason Biggs, Alyson Hannigan, Seann William Scott, Mena Suvari, Chris Klein ja Eugene Levy, palaa esittämään tuttuja hahmoja legendaarisen high school -komediasarjan mehukkaassa jatko-osassa.
