New Scientist News - Sony patent takes first step towards real-life Matrix

"The technique suggested in the patent is entirely non-invasive. It describes a device that fires pulses of ultrasound at the head to modify firing patterns in targeted parts of the brain, creating 'sensory experiences' ranging from moving images to tastes and sounds. This could give blind or deaf people the chance to see or hear, the patent claims"[link]:

Boing Boing: Are reusable water bottles dangerous?

Are reusable water bottles dangerous?
At The F Blog, former BB guestblogger Jenn Shreve writes about her quest to find an environmentally-reasonable yet non-toxic portable (and potable) water container:

Being the green gal that I am, but not wishing to sacrifice my own health for the planet (sorry, earth, just being honest), I decided just to re-use the flimsy plastic water bottles for as long as I could. I was happy with this solution for quite some time, until I learned the horrible truth: HARMFUL BACTERIA! Yes, with each refreshing sip I was backwashing germs into my water and providing them with a warm, wet place to grow.

So I did what any bacteria-fearing primate would do and bought a nice, reusable Nalgene bottle. Boy oh boy, nothing makes you look or feel more like a tree-hugging, mushroom hunting nature girl than one of those bright, hard plastic bottles! Until it comes out that Nalgene gives you BRAIN DAMAGE! Yes, Bisphenol A, used to make Nalgene bottles and other hard plastic projects, apparently seeps into the body and can, in certain doses, mess with the function of the brain. (I’m paraphrasing/exaggerating and not everybody agrees, so look it up.) I could almost dismiss the fear as environmentalist fear mongering, but it turns out that California legislators take the threat seriously enough to consider banning it in children’s products.[link]
