Microfluidic Chips Made With Shrinky Dinks

SoyChemist writes "When she started her job as a new professor at UC Merced, Michelle Khine was stuck without a clean room or semiconductor fabrication equipment, so she went MacGyver and started making Lab-on-a-Chip devices in her kitchen with Shrinky Dinks, a laser printer, and a toaster oven. She would print a negative image of the channels onto the polystyrene sheets and then shrink them with heat. The miniaturized pattern served as a perfect mold for forming rounded, narrow channels in PDMS — a clear, synthetic rubber."

Karma Burn

Just for kicks, I clicked through your posts, all the way back to what started this. For this, I had to wade through 2 additional "I was unfairly modded down" posts before I got to the post you thought was modded unfairly. All I can say is... you deserved every last one of your troll ratings.

To wit:
1) There was no information of any kind in that initial post. Unless you count "You're stupid!" as informational.
2) It led off with a spelling correction. Spelling corrections, especially when used in the context of determining IQ, are karma killers. With good reason - they contribute nothing and are designed to insult.
3) You invoked group-think. Accusing nerds on Slashdot is like accusing cats of being herd animals - it flies in the face of observation. Not to mention that you conveniently accused everyone who disagreed with you of group-think. That indicates that it is merely a cop-out to avoid facing the fact that you're plain wrong.
4) You brought an entirely irrelevant fact into the discussion - the user's sig.
5) Finally, your solution to your perceived problem is idiotic. IQ has nothing to do with whether guidelines are read or even adhered to. I suspect that you think that's an appropriate solution just because you scored above 100 on some IQ test, and think that that makes you special.

Here's something else: my post should be modded to -1 for being off-topic. Do I care? No. Why? Because I know that:
1) Karma is just a number that means nothing - people modded me up when I was posting at 1, and people modded me up when I had been modded down to -1.
2) On average, I contribute more than I flame. I know that a -1 mod here and there does nothing to my Karma.

Here's a suggestion: realize that your initial post was completely and utterly useless, and mods were correct in telling you so. Realize that the only way out of Karma hell is to contribute useful commentary. I suggest to start by reading the article, providing links in your posts, avoiding insults, etc.
