These stunning photos are on display at the Seattle Aquarium in a new exhibit, featuring the work of scientist & artist Adam Summers. The fish’s tissues have been stained with dye, a technique that is often used in the lab. But when perfected, it can also create gorgeous art.
One thing that makes fish particularly beautiful when dyed this way is that they are very complex—in some ways, more so than people:
For instance, fish have a lot more bones than, say, mammals. A person has over 200 bones in all, while there are 200 bones just in a fish’s head and the start of its vertebral column, Summers says. “That level of sort of repetitiveness draws the eye. It’s kinda cool.”
* You said something like… * “You look horrible.” * “Why are you even alive?” * … what? * You didn’t say that?
This is inspired by @nochocolate‘s analysis: “What was Chara Laughing At?” I’m a Chara sympathizer, but this moment in the game always haunted me. I’ve read many fan-interpretations, and NoChocolate’s is my favorite, even though it crushes my heart.
What is cryogenic distillation? A flask with compounds and a volatile solvent in it in connected to a tube what ends in a liquid nitrogen cooled trap while the whole system is closed. The volatile solvents (in this case dichloromethane) distills out from the room temperature flask and condenses into the −196 °C (77 K; −321 °F) cold liquid nitrogen trap. When all solvents are removed the product is left behind (hopefully crystals at the bottom of the flask) what was previously dissolved in the solvent.
Why is a balloon at the end of the whole system? It there would be no balloon or the system would be open to the atmoshere, the nitrogen trap would condense liquid oxygen and dry ice into the trap and not the solvent what we are want. The other reason is, that if the system would be closed, any external pressure would be “trapped” inside what could cause serious problems.
Most people’s first reaction: Oh my God! Is that a girl doing science?!
My first reaction: YOUNG LADY, WHERE ARE YOUR SAFETY GOGGLES, LAB COAT, GLOVES, AND ALL OTHER PPE?!
My second reaction: PUT YOUR HAIR IN A PONY TAIL SO YOUR HEAD DOESN’T CATCH ON FIRE.
My third reaction: TAKE OUT THOSE HOOP EARRINGS. THAT IS A SAFETY HAZARD.
My fourth reaction: I can’t believe the NIH posted this picture on their Facebook page. That is practically asking for a major fine from OSHA.
My fifth reaction: LABEL YOUR GODDAMN CHEMICALS! I don’t give a fuck if that is tap water with dye in it. For all I know it could be corrosive and/or lethal and/or bad for the environment to dispose of down the drain.
My sixth reaction: Oh look at her doing sciencey stuff. She has a lot to learn about lab safety, but one day she might be a role model to other aspiring female scientists!
Techniques in Organic Chemistry is basically the most complete presentation of lab techniques on hand for organic chemistry pupils—and the least pricey. This e-book is supposed to serve as a laboratory textbook of testal techniques for all students of pure chemistry. It is written to provide environment friendly toughen for guided-inquiry and design-based tests and initiatives, in addition to for conventional lab tests. Techniques in Organic Chemistry mixs explicit instructions for 3 totally totally different forms of laboratory glassware (miniscale, standard-taper microscale, Williamson microscale). It offers intensive protection of spectroscopic meanss and a strong emphasis on safety issues. It can be used along with any lab tests to provide the background and expertises vital for getting to know the natural chemistry laboratory..Techniques in Organic Chemistry
A New Technique Allows Scientists To Study Clouds In 3-D
With two digital cameras facing Miami’s Biscayne Bay,
Lawrence Berkeley National Lab scientists David Romps and Rusen
Oktem are collecting 3-D data on cloud behavior that have
never been possible to collect before.
The photos allow Romps, a climate scientist who specializes in
clouds, to measure how fast the clouds rise. This can shed light on a
wide range of areas including extreme precipitation and the ozone hole.
Perhaps most important, a better
understanding of basic cloud behavior will allow scientists to improve
global climate models. The largest source of uncertainty in today’s climate models is clouds.
“We want to answer a very basic question: With what speeds do clouds
rise through the atmosphere? This is very difficult to answer by any
technology other than stereophotogrammetry,” he said. “Knowing their
speeds is important for several reasons; the important one is that we
lack a really basic understanding of what processes control these
clouds, the levels they peter out at, and how buoyant they are.”
Nanoparticle Thin Films Self-Assemble in One Minute
The days of self-assembling nanoparticles taking hours to form a film over a microscopic-sized wafer are over. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have devised a technique whereby self-assembling nanoparticle arrays can form a highly ordered thin film over macroscopic distances in one minute.
Ting Xu, a polymer scientist with Berkeley Lab’s Materials Sciences Division, led a study in which supramolecules based on block copolymers were combined with gold nanoparticles to create nanocomposites that under solvent annealing quickly self-assembled into hierarchically structured thin films spanning an area of several square centimeters. The technique is compatible with current nanomanufacturing processes and has the potential to generate new families of optical coatings for applications in a wide number of areas including solar energy, nanoelectronics and computer memory storage. This technique could even open new avenues to the fabrication of metamaterials, artificial nanoconstructs that possess remarkable optical properties.
