Last week, I wrote a post (Be Your Own Boss) about the importance of having side projects in your daily life, and the huge payoff you can get back by investing a few hours a week in a side business. This week I wanted to take it one step further and give everyone some key steps in building your side business up once you have the groundwork setup."

The technique builds on work done by Cal Tech's Paul Rothemund, who found that DNA molecules can be made to 'self-assemble' into tiny forms [PDF] such as triangles, squares and stars. 'To make a chip, the scientists first create lithographic templates using traditional chip making techniques. After, they pour a DNA solution over the surface of the silicon and the tiny triangles and squares — what the scientists call DNA origami — line themselves up to the patterns etched out using lithography.' DNA-based chips may sound like crackpot tech, but those involved believe the methodology could lead to a new way of fabricating features on the surface of chips that allows semiconductors to be made even smaller, faster and more power-efficient than they are today."

The 1,400lb, Inflatable Re-entry Vehicle Experiment, or IRVE, was vacuum-packed into a 15-inch diameter payload "shroud" and launched on a small sounding rocket from NASA's Wallops Flight Facility. The 10-foot diameter heat shield, made of several layers of silicone-coated industrial fabric, inflated with nitrogen to a mushroom shape in space several minutes after liftoff. NASA said the test was the first time anyone has successfully flown an inflatable reentry vehicle. According to the cameras and sensors on board, the heat shield expanded to its full size and went into a high-speed free fall. [spam URL stripped]"

School Uniform To Block Cell Phone Emissions 153

Posted by samzenpus on Monday August 17, 2009 @12:37PM from the luddite-high dept.

Foehg writes "ForeignPolicy.com reports, 'A Belarusian textile company has developed a special school uniform that protects kids from electromagnetic radiation emanating from their cellphones. The uniform features a dedicated pocket that can store the phone and make it safe for those who wear it.'" Now someone has to create an oven mitt that can protect you from the harmful radiation given off by your microwave oven.

RevWaldo writes: "From Gothamist: A Brooklyn man can't sleep at night knowing that the bizarre inter-gadget relationship between his Sony Erickson PDA and his Maytag Magic Chef stove might leave him burned. Last Monday Andrei Melnikov discovered that his cellphone was turning on his stove when he got a call in the kitchen. The phone had been on the kitchen counter when it rang, and as he answered it and walked away, he recalls hearing a faint beep. Minutes later, he smelled smoke, and discovered that some plastic cookware left in the oven was on fire. The incoming call had somehow turned the broiler on high, a phenomenon which Melnikov demonstrated for his landlord and 1010WINS. They believe this is the first time this has happened in the three years since Melnikov has owned the stove and the phone, but since neither device is talking, nobody really knows how long this hot affair's been going on. Melnikov and his girlfriend have put a stop to it by unplugging the oven, and they're afraid to plug it back in because of their pet chinchillas. Maytag is sending someone to "fix" the problem, but will the lonely old Maytag man really have the heart to stand in the way of such fiery passion?"

Yes, you can disable this. The point of the message going around, at least the way I interpreted it, is that you should be aware if this and go disable it. It wasn't meant as an alarmist message to get people all up in arms.

Now, after in-depth analysis of data collected during the flyby, the small rocky body is starting to unveil its secrets. Steins is a rocky body gravitating like many others between Mars and Jupiter, but what sets it apart is its composition. "Of the 100,000 bodies in the asteroid belt, only 20 are like Steins," says Gaudon."

Submission + - Gravity well "parking lots" in space

Submitted by krou on Wednesday July 15, 2009 @11:43AM

krou writes: Via McClatchy newspapers: "[Lagrange points are] unusual locations where gravity loses its pull and a spaceship can loiter, rather like a marble at the bottom of a cup, without using a lot of fuel. Three of them are 930,000 miles outside Earth's orbit. One is between the Earth and the sun, and another is hidden on the far side of the sun. A pair of U.S. unmanned scientific satellites will pass through two of these sites this fall. NASA may eventually park a permanent space weather station at one of them."

They had no television or Internet and their only link to the outside world was communications with the experiment's controllers — who also monitored them via TV cameras — and an internal e-mail system. Communications with the outside world had 20-minute delays to imitate a real space flight.

You guys obviously didn't understand what I was getting at. Your euphemism for a bad thing could also be used to describe some other good thing (successful landing). I don't want my good landings lumped in with your crashes.

In order for this to work, you need to come up with some phrase like "very rough landing." Yes, it still includes a list of not so bad occurrences, but it's a lot less encompassing.

Mr. Anonymous Trolling Coward, I indeed have a very healthy number of close friends. You really should go find some better spies to stalk me.

Boosting it out of Earth orbit is much more expensive than doing a retro-burn to allow it to fall back to Earth. Do leave orbit, you have to give it enough energy to reach escape velocity. To have it fall back to Earth, just a "small" nudge to slow down and come back down.

What about the accrued interest on the fine? I also wonder, if they had not dropped the fine, could there have been some sort of arrest warrant, and who would've been the one to arrest?

Except that terrestrial parking is waaay too broad. The space shuttle also does terrestrial parking (Apollo, Gemini, and Mercury too, if you're talking about terrestrial as in Earth, not land). In fact, I do terrestrial parking everyday. How else am I going to get out of my car?
