Tiny But (Possibly) Deadly
Wednesday, April 30th, 2008A nanometer is one millionth of a millimeter. Nanotechnology is the science of controlling matter on the atomic and molecular scale.
Nanotech is where breakthroughs are likely. Forget about just the cancer-detection and other advanced medical tools it’s midwifing and the next-gen consumer electronics such as super-bright displays. On a planet that’s on the cusp of catastrophic climate change, nano-engineered materials have the potential to make a real difference. Imagine solar power cells that are far cheaper and more efficient; batteries that allow for more efficient electric cars; components that make cleaner coal-fired power plants. These and other applications are hardly trivial–they’ll save energy, reduce pollution, and maybe go a little way to making sure Times Square won’t be under water for the next millennium celebration.
That was from Good News: No Nano News. Due to the extremely small size of nano-particles, they can easily move into cells, and as they point out in that article, cross the blood-brain barrier. So while the technology is poised to potentially transform the world in a good way, there are dangers.
Think the government would be out front on this incredibly promising but also potentially deadly technology? Read EPA’s Lousy New Nanotech Program.
Why would the EPA be so lame? U.S. environment scientists report political meddling.
I don’t even use anti-bacterial soap. It’s like plowing up your lawn to get at the weeds. Sure you will kill a few weeds but your lawn is now fertile ground for anything that wants to grow there. There is such a thing as good bacteria. Using anti-bacterial soap is like over using antibiotics, you’ll likely breed something bad. In Too much nanotechnology may be killing beneficial bacteria they talk about silver nanoparticles in socks and dispensed by high tech washing machines may destroy benign bacteria used to remove ammonia from wastewater treatment systems.
I’m pretty sure someday people will infuse themselves with artificial blood just because it makes them feel better. I guess I didn’t expect it to be made of plastic.
Check out this tiny electric car. It’s more like a motorcycle with an extensive cover.
Eric Grohe is an artist who does amazing wall murals. Be sure to look at the ‘before’ pictures.
Electric circuits are made up of resistors, capacitors, and inductors, until now; Scientists Create First Memristor: Missing Fourth Electronic Circuit Element. A memristor’s resistance depends on how much charge flowed through it previously.
Who would have guessed watering your tomatoes with diluted seawater makes them healthier. Since I live far from the ocean, I don’t think I’ll be trying that trick this year.

This is a strange story about Mazda having to build a facility to destroy thousands of brand new cars.
