Eclectic junk from the four corners of the ‘Net. And pictures too!
A trifle gory, but good news never the less. Researchers are now looking at freezing cancer cells within a lung and simply letting it be absorbed into the body. The surgery is less destructive than chemo or other techniques. Sounds good.
Direct Freezing Technique Brings Hope to Lung Cancer Patients
How cool is this? A camera detects the movement of the fish and steers the robot accordingly. This is right up there with the roach robot and the monkey controlled robot arm. This is not only a fish driven robot, but it is now the first time one of our finned friends can explore on its own the strange alien world of the ‘surface’. One small stroke for a fish, one giant leap for all fish-kind! (I smell a movie script in here somewhere…)
Tonight I saw an outstanding episode of Mythbusters. The myth was ‘did the Confederate army create a two stage liquid fueled rocket that was fired 200 miles’. Sounds cool but if you know anything about the history of rockets this is way on the incredible side. Anyway, the result of the build session was a hybrid rocket made from a paraffin and carbon tube that had nitrous oxide shot through it. All using technology that would have been available during the civil war. Well maybe the TIG welders were in short supply back then, but the N2O was made the traditional way at M5. They did however censor the ingredients so you can’t go out and get high from it. Oddly, they in trying to make liquid oxygen Grant heated up mercury oxide. I guess that’s safe to show because you can’t find mercury oxide at the local hardware store. Not that you should do that, you do get O2 but you also get mercury metal. Fun stuff by the way but real bad to have around the house if your not careful. BTW, I had about 1/8 cup of it decades ago. And yes, I did make a tiny bit of it from the decomposition of mercury oxide.
Anyway, it was a great episode to watch and makes me want to know what they used to make the N2O. The actual rocket used a commercially bought cylinder of N2O just to save time but if they had wanted to they could have done it on their own.
They also made gun cotton ( nitrocellulose ) in a kid safe way but that you can’t make a rocket out of, just things that go boom. And we don’t want that. Not that it’s hard to make, its actually pretty easy. You just take… Oh wait, I don’t want to tell you that do I. 😛
Now this in a cool hack. He crammed a Famicon (Nintendo) into a hand held unit that he built from the ground up.
If your a harcore coffee drinker you might want one of these for your desk.
Equipped with a 19 bar high pressure pump, thermoblock heating, and manual volume control (??), the C90 guarentees that the cup of espresso you make is up to your standards.
