What's the Buzz?

When I saw the headline: "Low Buzz May Give Mice Better Bones and Less Fat", I thought, why those lucky labrats, smoking the chronic and getting in shape at the same time. However, it turns out that the buzz in question is an electrical buzz.

It's still an interesting story, mice stand on plates that produce a low frequency buzz for 15 minutes a day and they end up with 27% less body fat and greater bone density than their non-buzzed control group brethren. Of course the results are preliminary and all that.

Interestingly, the NIH now plans a human trial using elderly people in assisted living centers. Who says we don't respect our elders in the USA??
