3D nano printed man.

Machines, known as two-photon lithography printers, can produce detailed structures as small as a grain of sand.

Vienna University of Technology researchers Jan Torgersen and Peter Gruber, led by materials science and technology professor Jürgen Stampfl, took the printing process from millimeters per second to five meters per second, a world record.

Lovely mnemonic for Pi involving liquor and physics.

It goes:

Synthesis of Anthropomorphic Molecules: The NanoPutians

“Described here are the synthetic details en route to an array of 2-nm-tall anthropomorphic molecules in monomeric, dimeric, and polymeric form. These anthropomorphic figures are called, as a class, NanoPutians. Using tools of chemical synthesis, the ultimate in designed miniaturization can be attained while preparing the most widely recognized structures:  those that resemble humans.”

Alessandro Volta invented the battery but also hung out with Napoleon and made methane ignited airguns!


.

In 1800, as the result of a professional disagreement over the galvanic response advocated by Galvani (he of the electricty twitching frog leg’s fame), he invented the voltaic pile, an early electric battery, which produced a steady electric current.[6] Volta had determined that the most effective pair of dissimilar metals to produce electricity was zinc and silver. Initially he experimented with individual cells in series, each cell being a wine goblet filled with brine into which the two dissimilar electrodes were dipped. The voltaic pile replaced the goblets with cardboard soaked in brine. The battery made by Volta is credited as the first electrochemical cell. (via wiki)

Note that Volta is also the first to characterize the gas Methane. In fact, he even devised an air gun contraption that relied on igniting the flammable gas (see this link for pictures). For this and his battery invention, he was made a count by Napoleon.

I find it wonderfully amusing that Marie Curie’s papers are still radioactive.

Many library collections use special equipment, such as special gloves and climate-controlled rooms, to protect the archival materials from the visitor. For the Pierre and Marie Curie collection at France’s Bibliotheque National, it’s the other way around.

That’s because after more than 100 years, much of Marie Curie’s stuff – her papers, her furniture, even her cookbooks – are still radioactive. Those who wish to open the lead-lined boxes containing her manuscripts must do so in protective clothing, and only after signing a waiver of liability.

Grimace speaks to a Geneticist

Some more silliness I wrote a few years back. Originally published at McSweeney’s.

By DAVID NG

GRIMACE: What am I?

GENETICIST: That is a very interesting question indeed. And we should begin by briefly discussing your known history. According to your records, you were born as “Evil Grimace,” with four deft arms, and a penchant for amusing yourself by stealing milkshakes from small children. Then, in 1974, you experienced a change of heart, a loss of two arms, and a metamorphosis into what is your current incarnation—a supposedly warm, gentle, and seemingly living representation of the “embodiment of childhood.”

GRIMACE: Is that why I have only one orifice?

GENETICIST: Perhaps so, as childhood is a period marked by the most basic of bodily functions. In truth, it is that kind of interesting nuance that makes me suspect your being a genetically modified organism. Furthermore, the timing of your appearance coincides perfectly with a social phenomenon during the ’70s. A time when discussing human cloning was culturally fashionable, when books like The Boys From Brazil and In His Image appeared on bestseller lists.

Also, you are purple like a giant areola.

GRIMACE: How can I find out more?

GENETICIST: A promising course of action is to try genetic counseling. Which, in the conventional sense, suggests that we investigate your network, both in family and in friendship. This is to help construct a more complete picture of your being and, more importantly, your past. From this, we will have a firm starting point from which to build.

GRIMACE: But I have no family, no real friends, and Ronald, frankly, scares me. What other alternatives do I have?

GENETICIST: Ronald scares us, too, but that is for another interview. Under those restrictive circumstances, one possible alternative is to contact nonacquaintances with similar traits. Perhaps someone like Barney the Dinosaur, who is also big, purple, and waves a lot like an idiot. Similarly, we could simply forge ahead and arrange for a genetic test. This is a process that will allow us to peer at your very own genetic code, and is something that will surely resolve the mystery that surrounds you.

GRIMACE: Like why I am so popular with the ladies?

GENETICIST: Yes, exactly! In some respects, you could be the perfect metaphor for what is both wonderfully right and terribly wrong about genetic manipulation. Due to the marvels of this technology, you appear to have luxury, wealth, fame, as many women as you desire, and yet you have no identity, no origin. If ever there were such a thing, you are an organic black box.

GRIMACE: I think it’s because the ladies like my massive tongue.

GENETICIST: Which is magnificent indeed! In fact, seeing it now, I am struck by how similar your appearance is to that of a tongue, a taste bud, to be specific. To entertain this avenue, I ask that you take a moment to study and answer these five carefully designed questions:

(1) Do you find that you sweat profusely such that you are always, to a certain degree, moist?

(2) Do you find yourself a constant victim of paper cuts, specifically when handling your letters of correspondence?

(3) Do you find you enjoy bathing in scented waters but are repelled by thoughts of swimming in the sea, perhaps fearing that the salt will further constrict your already-tender skin?

(4) Do you notice that when you are jumping on a trampoline, the consonant sounds “l,” “n,” “d,” and “t” appear as if by magic?

And (5) Do you, during the winter season, always find yourself inexplicably and inconveniently stuck to cold metal structures?

GRIMACE: Hmmm, maybe the trampoline one, but otherwise, no.

GENETICIST: Ah, well, it was only a hypothesis. It appears that we will order that genetic test after all. But first, I feel compelled to present this stern warning: these tests can be excruciatingly accurate sometimes. You may, quite frankly, be disappointed with the result. You see, I cannot control the outcome of the test. I do not possess that power. I am not God. I am, sadly, only a geneticist.

Is Grimace an example of yeast genetics gone bad?

Should give credit, where it’s due – although I made this graphic, the idea for the graphic isn’t mine. Saw something similar in an ad for some graphic design school. If anyone else knows what I’m talking about, do send a note to me. O.K. enough with the references to Grimace…
