Tying Molecules In Knots

Med-trump writes "Scientists report that they have made a non-DNA molecular knot. They created a 160-atom-loop with five crossing points, a molecular pentafoil knot. The researchers used a technique known as 'self-assembly' to prepare the knot in a chemical reaction. Apparently 85% of the elasticity of natural rubber is due to knot-like entanglements in the rubber molecules' chains."

Yours was actually the second post.
You got the first failure, though.

Why don't you tell us your gay zero Kelvin copypasta joke? Then you could have the second failure.

Sorry guys, I did this knot with my sweatpants drawstring like 6 months ago.

It took me long enough to learn how to tie my shoes. I hope this won't be on the final exam.

To be honest I thought that this was what GP said until I went back and read it a second time...

protein knots (3, Interesting)

digitalderbs (718388) | more than 2 years ago | (#38004938)

Actually naturally-occuring protein knots have been known for some time now. See [] for example. This appears to be one of the first synthetic knots.

"Why use quotes?" (2, Interesting)

Anonymous Coward | more than 2 years ago | (#38004962)

You do know that "self-assembly" isn't really a technique. That's like writing that Google updated their search algorithm using a technique known as "writing code". Self-assembly is just a term for things that assemble by themselves.

It helps marketing identify 'buzzwords'
