Good Vibrations Keep It Ticking

1 Heart May Be a Power Source for Pacemakers

Vibrations from heartbeats could one day power cardiac pacemakers, suggest engineering researchers from the University of Michigan. The researchers designed a device that can harvest energy directly from heartbeat reverberations. Vibrations would be turned into electricity to run the pacemaker or an implanted defibrillator. The device would use a hundredth-of-an-inch "piezoelectric" ceramic material that would catch heartbeat vibrations and briefly expand in response. While the researchers have detailed blueprints, they haven't yet built a prototype. Heart-powered devices would eliminate the need for additional surgeries to replace pacemaker batteries, which work for only five to 10 years. The research is published in Applied Physics Letters.

You're Not a Slut After All

2 Rush Limbaugh Says Sorry for Slut Remark

Believe it or not, Rush Limbaugh didn't mean to personally attack Georgetown University law student Sandra Fluke when he called her a "slut" for testifying in favor of President Obama's new birth control coverage rule. Limbaugh apologized to Fluke today, reports Los Angeles Times. The talk show host says that he was attempting to be "humorous," but now apologizes to Fluke for his "insulting word choices." The new Obama rule for birth control coverage requires employers and insurers to offer coverage for contraceptives without co-pays or deductibles.
