Technetium Cow
A technetium-99m generator, or colloquially a technetium cow or moly cow, is a device used to extract the metastable isotope 99mTc of technetium from a source of decaying molybdenum-99. 99Mo has a half-life of 66 hours and can be easily transported over long distances to hospitals where its decay product technetium-99m (with a half-life of only 6 hours, inconvenient for transport) is extracted and used for a variety of nuclear medicine diagnostic procedures, where its short half-life is very useful.
The first technetium-99m generator (picture), unshielded, 1958. A Tc-99m pertechnetate solution is being eluted from Mo-99 molybdate bound to a chromatographic substrate.
Purification of 1g of impure azulene by column chromatography. Eluent: hexane. It separates easily from any other impuries.
Approx. 400mg was the pure azulene, not so bad, not so bad(:
Large scale coming soon(:
An Open Letter to the MLB and FOX
To whom it may concern:
After the Red Sox and Rays last night had the benches clear, I was really ready to watch tonight’s game. It wasn’t just because tensions would be heightened, but also because there’s a number of other great storylines going on, and I really enjoy watching the Red Sox.
But you’re blacking out the game. Sure, FOX has the game. But they’re showing us the Phillies-Cardinals down here in the DC area. So even though you do not have the game on TV, you’ve made it impossible for me to watch the game at all. There’s no second broadcast of the game on a different channel. There’s no MLB.TV broadcast. There is literally no way for me to watch this game unless I hop in my car, drive to an area where it is not being blacked out, and turn on a TV there.
There are many angry fans who deal with this every week. Sure, you think you’re getting fans to watch other games, so maybe you’ll increase interest in more teams. Which is commendable. I’m not sure many general fans across the country had ever seen a game hosted in Tampa on broadcast TV before the Rays were in the World Series. But you’re also angering fans with this tactic. If the main FOX broadcasting team is so great - a tangent I’m not even going to start in on - then plenty of fans would be happy to flip back and forth between both FOX games to watch. Instead, out of spite, I’m just going to turn on the radio to be able to follow the game the only way you’re allowing me. And I bet a number of other people are just going to find other ways to spend their Saturday and hope the highlights are sufficient.
I know baseball isn’t dying - attendance is up, ratings are up, more small-market teams are getting good local TV deals - so contrary to all the usual articles that get written about it, the sport is in a really good position. But man, you do try to find ways to go out of your way to anger and alienate the hardcore fans you do have.
Give us a way to watch all the games. If you can’t do that, you really don’t care about your fans.
We knew we weren’t a priority. But stop reminding us.
Sincerely,
Dante Shepherd
The main reason why I’m hesitant to get MLB.tv when I move. Also, all postseason games are blacked out. MLB can go to hell.
Never not reblog.
Reblogging just because of Boston City Hall in the background. Brutalist Architecture at its finest.

It's Okay To Be Smart: You May Have Heard About a Study Recently Linking Coffee-Drinking to Living Longer . . .
Here’s a randomly-selected list of news headlines about it:
- “Coffee drinkers may live longer, study suggests” … ok, not so bad. Surely the study suggests that somewhere? (More about that later)
- “Can coffee help you live longer?” … Do you know the answer? Then just tell me. I mean, are you…

Zeise’s salt
Potassium Trichloro(Ethene)Platinate(II), is the chemical compound with the formula K[PtCl3(C2H4)]·H2O. The anion of this air-stable, yellow, coordination complex contains an η2-ethylene ligand. The anion features a platinum atom with a square planar geometry. The salt is of historical importance in the area of organometallic chemistry as one of the first examples of an alkene complex.
Zeise’s salt received a great deal of attention during the second half of the 19th century because chemists could not properly explain the molecular structure of the salt. This question remained unanswered until the advent of x-ray diffraction in the 20th century.](http://25.media.tumblr.com/tumblr_m4k8l0TvU41rw1p5qo1_1280.png)

Psychedelic Neurons
From a human autopsy; this brain slice has taken on a range of psychedelic colors thanks to a neuroscientist. Green is the infection by a lentivirus, red for neurons and blue for the nuclei of brain cells. Immunohistochemistry was used to introduce the red and blue to the brain slice.

YES, TUMBLR, I UNDER-FUCKING-STAND.
WE ALL UNDER-FUCKING-STAND.
WHY DON’T YOU UNDER-FUCKING-STAND, TUMBLR, THAT WE USE MISSING E BECAUSE IT IS AWESOME?
STOP MAKING ME TELL YOU THAT I UNDERSTAND, AND WORK ON DEVELOPMENT SO I DON’T NEED MISSING E.
80% of my outrage coefficient could be reduced by just letting Wil be angry FOR me.
But seriously. I understaaaaand.

Could your next hard drive be made with DNA?
Okay, so maybe not your next one, but in a few year’s time? Maybe your storage will be writ across DNA itself. Researchers at Stanford have developed a method to store binary code on DNA. Dubbed the “recombinase addressable data (RAD) module,” the method controls the synthesis and degradation of two proteins, integrase and excisionase. With RAD, a particular section of a microbe’s DNA is tweaked to glow either red or green under ultraviolet light — and it can be switched back and forth at will.
What really sets this biological bit apart from others is that it can be reliably, and non-destructively, switched back and forth. It took the researchers three years to come up with the precise cocktail of proteins to achieve this feat. Since the switch is programmed into the microbes, it remains in its current state while the cell doubles, and can then be modified if needed.
“Programmable data storage within the DNA of living cells would seem an incredibly powerful tool for studying cancer, aging, organismal development and even the natural environment,” said synthetic biologist Drew Endy, but we’re a while from getting it to a more useful computational state. It’s currently got around a 30 minute switch time. As Endy put it, “We’re probably looking at a decade from when we started to get to a full byte.”
Oooh, GFP, my favorite. Well, a mutant version, anyway…

Accuracy takes power: one man’s 3GHz quest to build a perfect SNES emulator | Ars Technica
Video games are a piece of our history, and we need to respect the fact that there is a “true” form they had when released. Imagine if we only had a JPEG of the Mona Lisa, a RealVideo stream of the moon landing, or a MIDI rendition of “Walking in the Air.” We have the ability to keep our past alive, and I feel like it’s almost a duty to do so.
