Is there no end to the wonder that is a carbon nanotube? The things can be used to make really black bulletproof objects and slow, tiny computers!
Those computers are hard to make, though. Nanotubes are, well, small and sometimes hard to work with, resulting in a lot of failure. IBM has a different take, though. Instead of arranging the nanotubes to replace traditional circuits by hand (or, more likely, traditional tools), Big Blue is stringing them together with DNA molecules. Once it's all put together, you slip the DNA out, and--ta dah!--you've got a grid of nanotubes

San Francisco is getting to be a pain to fly in and out of, which, sadly, I'll be doing within the week. At the end of January, the local TSA authorities started asking fliers to remove each individual gadget or piece of electronics they happened to be carrying. After some of the major blogs picked the story up, the TSA investigated and then issued an apology (sort of, while still managing to be both head-patting and self-congralatory) on its own blog yesterday.
Today the Washington Post reports that things are even worse: "A few months earlier in the same airport, a tech engineer returning from a business trip to London objected when a federal agent asked him to type his password into his laptop computer. "This laptop doesn't belong to me," he remembers protesting. "It belongs to my company." Eventually, he agreed to log on and stood by as the officer copied the Web sites he had visited, said the engineer, a U.S. citizen who spoke on the condition of anonymity for fear of calling attention to himself."
Other passengers have had their laptops seized and unreturned.

Stanford engineers have produced a silicon chip built on carbon nanotube wires that conduct digital information at the speed of commercial computers.
"This is the first time anyone has been able to show digital signals going through nanotubes at 1 gigahertz [a billion times a second]," Stanford professor of electrical engineering H.-S. Philip Wong said in a statement "There had been a lot of expectations that nanotubes could do this, but no experimental proof so far."
I know, I know, my old, decrepit work computer is already chugging along at 3.2Ghz and I still can't stand it. So what's the big deal?
Well, for starters, they're really, really black.

Graphics Card cc Johnny Anthony Evans
It would take most dual-core PCs about two months to crack an eight-letter, NTLM-hashed Windows Vista password using brute force techniques at 10,000,000 passwords per second. With a decent graphics card, now you can hack the system in just three to five days. Huzzah!
