  7. Not radioactively powered but a trickle charge by planckscale · · Score: 5, Funny
    It looks like this mostly a development into boosting the charge of an otherwise ordinary Li battery. If it keeps my cell battery charged for over a month as opposed to every 4 days than I could care less if my ear mutates into a chicken wing.

    " Once these challenges are overcome, a promising use for nuclear microbatteries would be in handheld devices like cellphones and PDAs. As mentioned above, the nuclear units could trickle charge into conventional batteries. Our one-cantilever system generated pulses with a peak power of 100 milliwatts; with many more cantilevers, and by using the energy of pulses over periods of hours, a nuclear battery would be able to inject a significant amount of current into the handheld's battery.

    How much that current could increase the device's operation time depends on many factors. For a cellphone used for hours every day or for a power-hungry PDA, the nuclear energy boost won't help much. But for a cellphone used two or three times a day for a few minutes, it could mean the difference between recharging the phone every week or so and recharging it once a month."

    The primary downsides to Nuclear Batteries is that they are expensive and they don't scale.

    They're also not rechargable :p

    NEWS CAMERA FOCUSES ON GROUP OF BEARDED MEN WEARING DIRTY CAMOFLAGE JUMPSUITS. THEY ARE STANDING BEYOUND A FENCE AT THE END OF AN AIRPORT RUNWAY.

    REPORTER: Thanks, Dan. I am here at the end of runway 4, where we are seeing a shift in Al-Queda's tactics today. They seem to be employing some sort of revolutionary new tactic...

    CAMERA SHOWS A TERRORIST HEAVE A BRICK IN THE AIR AS A JET TAKES OFF, ROARING OVERHEAD. THE BRICK FLYS ABOUT 20 FEET UP, BEFORE FALLING TO THE GROUND NEXT TO THE VISIBLY UPSET TERRORIST.

    Reporter: Back to you, Dan.

  12. First observation of electron decay by Cardbox · · Score: 5, Funny

    Hidden away in the article is a discovery that will revolutionize our understanding of particle physics and cosmology:

    Nickel-63 is ideal for this application because its emitted beta particles travel a maximum of 21 micrometres in silicon before disintegrating
    This must imply that there exists a lighter lepton than the electron. Goodbye, Standard Model!
