Nanocar Wins Top Science Award 175

Lucas123 writes "A researcher who built a car slightly larger than a strand of DNA won the Foresight Institute Feynman Prize for experimental nanotechnology. James Tour, a professor of chemistry at Rice Univ. built a car only 4 nanometers in width in order to demonstrate that nanovehicles could be controlled enough to deliver payloads to build larger objects, such as memory chips and, someday, even buildings, like a self-assembling machine. Tour and a team of postgraduate and postdoctoral researchers constructed a car with chassis, working suspension, wheels and a motor. 'You shine light on it and the motor spins in one direction and pushes the car like a paddle wheel on the surface,' Tour said. The team also built a truck that can carry a payload."

We actually had an interesting situation where I work (spacecraft operations). We had a senior aerospace engineer depart after 15 years to become an airline pilot, of all things (decided to turn a hobby into a job).

About a year later, he came back part time because the routes he flew left him with large blocks of free time at irregular periods during the month, and he was getting bored (because before his "hobby" was flying....and he stopped doing that on his days off!).

It was a win-win situation. He'd give us 40-60 hours a month of hourly work when it was convenient for him. We kept his hopper full of things like documentation, training, and other stuff that most senior guys consider dreg work. Even though he now has enough seniority to avoid pilot furloughs, he'll volunteer to drop his flight hours if the airline needs him to. He just increases his hours with us (and he's so good, we'll take whatever he gives us up to full time).

Since he's not interested in advancing up the ladder, he really does a great job on this low-visibility stuff that really helps an organization run well if it's done right.

I've been doing very well - but 2008 was not my favorite year. Not a horrible year. Just not my favorite :) I blew my knee out and perhaps have ended my sports career forever. And I ended up in a couple of contracts that just sucked the life out of me. It took time to recover.

So, 2009 will be the year I try having more time than money :) If it doesn't work out, at least I'll go back to having other people set my agenda and be a little more grateful.

How about you? How did 2008 turn out?

Dies for me at my ISP's border router; I've never seen a traceroute die so fast. Only 2 hops before it goes dead. It makes me think that the global BGP tables are blackholing the subnet.

I checked a bunch of BGP looking glasses and they all report "Network not in table", as in there are no global routes for that IP address.

I understand your point, however this particular software is basically a system for tracking vehicle "funnies" on the ground, it's not something that is in the loop of the vehicle flight software or something used to make critical decisions. The old system is pretty dated and unwieldy to use (I've used it, I work for NASA). We're obligated to try out cheaper alternatives to custom code to see if it works for us without compromising what we are trying to do.

Sometimes it does work for us - the Mission Control Center workstations and the onboard command and control laptops on the Space Station were all recently converted to Red Hat. It is in many ways better than the old proprietary unix solutions because with the source it's easy to do our own mods to the software. We still test the daylights out of it since that is critical software, but it's a lot easier to support since we have the source code and can do our own bug in-house bug investigations, patch it, or rip out things we don't want/need.

I guess I'll take exception to calling astronauts the "annointed elite". Read through the biographies of the current crop of astronauts, and you'll see a pretty broad demographic of military officers, researchers, doctors, and even a teacher. Almost all came from a middle class background and got where they are through hard work.

The astronaut selection process is completely merit based, albeit extremely selective (since there's way more applicants than openings).

I'd be interested in what your propose NASA do to put "normal citizens" into space. Right now NASA and a couple of other government agencies are SpaceX's main funding source, and SpaceX probably has the best chance of coming up with a private ride to orbit for normal (albeit rather rich) citizens to go to space based on this work.

(Useful) Stupid BlackBerry Tricks? 238

Two great stories in one comment :)

I've gotten review copies of two different technical books, but I only really made good on one of them. It's one thing if you buy the book for reference reasons - but to read it cover to cover takes me forever, I keep going off on daydreams of my own and then having to reread everything. As such, I have all the more respect for your abilities, and your philosophy about taking books.

As for my own philosophy, I'm all about singing till the cat eats me - We'll see how that pans out, heh.

Sound Bites of the 1908 Presidential Candidates 410

roncosmos writes "Science News has up a feature on the first use of sound recording in a presidential campaign. In 1908, for the first time, presidential candidates recorded their voices on wax cylinders. Their voices could be brought into the home for 35 cents, equivalent to about $8 now. In that pre-radio era, this was the only way, short of hearing a speech at a whistle stop, that you could hear the candidates. The story includes audio recordings from the 1908 candidates, William Jennings Bryan and William Howard Taft. Bryan's speech, on bank failures, seems sadly prescient now. Taft's, on the progress of the Negro, sounds condescending to modern ears but was progressive at the time. There are great images from the campaign; lots of fun."

Hey! You can't just have a car accident and post something where we can't write in and let you know that we're thinking of you and that we're glad you're alive and not splattered across the side of a Semi Trailer somewhere.... well ok the truth is I'm just damn glad that you could post at all.

Get well and don't go jumping around early, make sure you give yourself a lot of time to recover. And sleep lots. See if you can get yourself hooked on daytime tv :)
