Keck clip they are.
While these are almost certainly patented, maybe by changing the material clips could be printed without legal trouble. Keck clips can fall apart if exposed to (eg) HCl gas, so printing PTFE versions would be useful.
I like the adaptor idea - and it could be extended to any labware if someone figures out how to print glass. No more searching for that B24 condensor!

Shold have done something in base-4, because, you know, there's four bases in DNA :)

There is an interesting TED talk on presentations, and how they flow, that used jobs as an example:

Althought the paper manages not to mention it, the chemistry they are doing here is (the alkyne azide cyclisation) is part of "click" chemistry, which is quite well known.

What the paper doesn't really say is whether they hope to accomplish anything further with this. As with all biomimetic reaction, it seems (to me) that synthesising a single step in the process may be intersting, without doing all the previous steps, is there any practical point?

Not a problem, we can outsmart them:
"Killbots have a pre-set kill-limit. Knowing their weakness, I sent wave after wave of my own men at them, 'till they reached their limit and shut down"

work gave me an Asus Eee slate to use. Using one note for drawing, annotating ck.is great Handwriting is also pretty good most of the him! (win 7) Hope I don't sand like a corporate whore

Remember, this is the country that is putting its scientists on trial for failing to predict and earthquake.

That was what I assumed it was too, and TFA didn't give any details ("Ride the Light" sounds like a new rollercoaster).
I would imagine, with the amount of use this technology would get (i.e., number of launches) that any ozone created would be tiny as compared with the amount in the upper atmosphere.*

But I dont see how this will get us into space. The higher the craft, the less efficient the push per beam of light.

* This argument may have been made about CFCs, exhaust emission, etc so I may have to eat my words...
