Tiny-Wheeled Robots, the Surgeons of the Future
Tiny-Wheeled Robots, the Surgeons of the Future- Softpedia
I see at least two robots there, that I wouldn't want inside my body ..... :)
The robots are barely over 3 inches long. One team member predicts that when production ramps up to the point where they could afford custom electrical components, the size of the robot could be cut in half.

Researcher Develops World's Smallest Car
Researcher Develops World's Smallest Car
Built at Rice ... it is *Much* too small to haul even one grain of rice. Thankfully, scientists won't have much trouble figuring out a multitude of nanoscopic materials with which to fill it.
The nanocars have to be heated to almost 400 degrees fahrenheit before strong electrical bonds to the material surface break enough to allow them to roll. (Paper bursts into flame at 451 degrees fahrenheit, if you recall, so this probably eliminates the possiblity of them hauling nanoscopic newspapers ..... ;-) )
In follow-up work, the Rice team has created a nanocar driven by light, and a nanotruck capable of carrying a load.

Hubble Looks for Possible Moon Resources
Hubble Looks for Possible Moon Resources
With the possiblity of mining ilmenite on the Moon, you have the ability to extract breathable oxygen, along with iron and titanium for construction purposes.
This Aristarchus crater was at one point, going to be a landing site for one of the discontinued Apollo 18, 19 or 20 missions.

A little pricy at over $2000 USD per square foot, but well worth it if it is ever needed. When production ramps, the price will fall.

EFF cracks Secret Service code
p2pnet.net - the original daily p2p and digital media news site
It bothers me that honest citizens have to pay extra to have crud like this put in our consumer electronic equipment. In this case, it degrades the quality of our photos. To what extent I am not sure. I'm sure the government scientists picked the color least likely to be noticed. (yellow) But those pixels have to degrade the image, and must replace some pixels that would otherwise be there.
People go to the trouble of compressing images with lossless computer technology (data compression) only to have it thwarted by something like this.
Who watches the watchers?

Survival trick of loose cancer cells
New Scientist News - Survival trick of loose cancer cells
Could it be, that metastatic tumor cells -- instead of ignorantly moving as rogue cells through the body -- are actually mistakenly homing in on some chemical signal, similar to the way leukocytes home in on infection or inflammation? I think this way of looking at the problem, turns the conventional wisdom on it's head .....

They say slowing your vehicle down pays in the long run. Guess they were right ... This robot car, named "Stanley" drove by itself 131.6 miles through the desert, and averaged 19.1 miles an hour .......
For which the team got paid ......... $15,197.57 PER MILE !!
Not a bad payday..... :)
Gas is expensive, but at that rate, you could recoup about 5000 gallons a mile ....... ;-)

Slashdot | Internet Partitioning - Cogent vs Level 3?
OK .. Blogger has some kind of bug, that automatically posts, when you left-click and/or hit RETURN too early in the session .... SHEESH !!
Anyway, I find it surprising that in this day, the Internet can still be partitioned off so easily. I hope the customers vote with their wallets and destroy the offending party(s). A better solution would be some kind of re-regulation by the powers-that-be, that would allow other companies to step in, and prevent this silliness.

Cassini pictures spongy Hyperion
BBC NEWS | Science/Nature | Cassini pictures spongy Hyperion
Spongy Indeed! ... It appears to me, in examining the enlarged photo of Hyperion, that the whitish cliffs are in fact the walls of a Mega-Crator that spans over 70% of the width of Hyperion.
And that several hundred smaller craters have slowly subsided in a regolith collapse, into the hollow core of Hyperion.
There is one larger crater near the bottom of the photo that ... while it's walls remained intact and frozen ... it appears that it's bottom was ground away, and flattened by it's slide down the whitish cliff walls.
