'Femtomolar Optical Tweezers' May Enable Sensitive Blood Tests

Cutting-edge "tweezers" are so sensitive that they can feel the tell-tale tug of tiny concentrations of pathogens in blood samples, yet don't ever need to be sterilized--or even held--as they are ephemeral and weightless.

•	A computer wallpaper for makers...
	Hi all, So, earlier this evening while sitting at my desk trying to work and failing miserably, I looked up at my computer and thought, "wow, there's a whole mess of empty space right there in front of me. Wouldn't that be a great place for an engineering/maker's cheat sheet?" Assuming that somebody would've thought of this already, I googled "desktop background engineering cheat sheet" in a number of permutations, to no avail. I was disappointed. Which brings me to the question I'd like to pose to the maker community. If you're like me and do a great deal of your work with your laptop nearby, you might find some utility in having a cheat-sheet printed there on the desktop for you to use. What would you most appreciate having on that cheat sheet? Resistor color codes seem an obvious one, as well as basic electronics formulas, trig rules, conversion tables...Any other ideas? Anyway, let me know. I've put up a preliminary version of the background here (pretty shotgunned, I can think of a bunch of things I wouldn't mind having on it already): http://www.box.net/shared/dquk1i8ffz ...and the Photoshop document for it here: http://www.box.net/shared/dizh8crqmr Apologies for not quoting the sources that I got the graphics from...If this irritates someone, I can certainly track down the graphics. Also, I fully own up to the fact that I don't know the first thing about Photoshop - hope my design basis isn't too crummy. Cheers, J.L

	In 752, Japanese Empress Koken wrote a short poem about the summertime yellowing of a field in what is thought to be the first account of a viral plant disease. More than 1,250 years later, scientists concluded that the virus Koken described was part of the particularly insidious geminivirus family that continues to decimate tomato, tobacco and cotton crops worldwide.
