There’s an old saying that, on the Internet, no one can tell you’re a dog. It turns out that that’s probably not true. In fact, anonymity is going to be getting hard with this kind of analysis.

…differences remain in the way that people tap out their electronic secrets. Internet users have characteristic patterns of how they time their keystrokes, browse Web sites, and write messages for posting on online bulletin boards. Scientists are learning to use these typeprints, clickprints, and writeprints, respectively, as digital forms of fingerprints.

While the aims of this research are to strengthen password security, reduce online fraud, identify online pornographers, and catch terrorists, the technology is raising some troubling possibilities. “It’s a bit scary,” says Jaideep Srivastava, a Web researcher at the University of Minnesota in Minneapolis. “The privacy implications are huge.”

I’ve also noticed the huge increase in image spam for stock scams. The solution to this seems pretty simple to me. Just block any email with an image in it.

Sure, a lot of people who like to flood their friends’ mailboxes with pictures of cute puppies will whine, but is this really a critical need for email? Much of the evil of spam is enabled by the bloat that emails have become in recent years, with HTML and embedded graphics (just one more bit of proof that Microsoft is evil).

Just say no, mail servers, and go back to ascii. And for users, if you want to show someone a picture, send them a link, or attach it.

Behold: molecules that can walk and deliver payloads in a straight line. This could lead to some interesting breakthroughs.

Here are some interesting pictures of semi-conductor junctions and charge carriers, at the nano-scale:

“There’s no major surprises here,” says Andreas Heinrich of IBM Almaden Research Center in San Jose, California. “But the fact that they are actually imaging the electric properties is a big step forward.” Surprises may show up when de-vices shrink below around 50 nanometers, Heinrich says, because dopant atoms will be so scarce that their individual positions may affect the de-vice’s function. Tomihiro Hashizume of Hitachi’s Advanced Research Laboratory in Hatoyama, Japan, says the ability to see precisely how charge carriers move “will be indispensable for the further progress of de-vice miniaturization.”

A surgical microbot.

The scientists are designing the 250-micron de-vice to transmit images and deliver microscopic payloads to parts of the body outside the reach of existing catheter technology.

It will also perform minimally invasive microsurgeries, said James Friend of the Micro/Nanophysics Research Laboratory at Australia’s Monash University, who leads the team. The researchers hope the de-vice will reduce the risks normally associated with delicate surgical procedures.

The piezoelectric approach seems promising.

How much further behind will be nanobots?

Conventional wisdom has long been that there are many types of cancers, and that we won’t come up with a single “cure for cancer”–that there will be many different treatments for different problems. But some researchers think that they may have in fact found a low-cost drug that cures many types of cancer, with few side effects.

This seems like pretty big news.

Developments in photonic ICs.

I’d think that Cisco must be considering an acquisition.

Moonbats (and non-moonbats) often accuse me of being a “right-winger” and a “conservative.” I guess that’s because I don’t think that George Bush is Hitler reincarnated, and that removing dictators who support terrorism is a good thing. But if anyone really wants to know why I’m not a conservative, Will Saletan has an interesting example. So-called liberals are afraid of cloned animals and cloned food. Conservatives seem to look askance at cloned humans. I’ve got no problem with either.
