Self-Assembling DNA Pyramids
FleaPlus writes "Physicists in England and the Netherlands have unveiled a technique for constructing rigid DNA pyramids. With the technique, trillions of d4's can rapidly self-assemble from a solution of single-stranded DNA. The scientists also showed that single DNA strands called linkers could be used to attach the tetrahedra to each other, acting as a possible building block for 3D nanofabrication."
Man those D&D games are getting complicated!
Oh... nevermind

Let my nucleotides go!
I knew my DNA had to be a pyramid.
It is more in line with my shape, gets wider the farther you go down!
Just as soon as you send $1.00 each to the following people, then place your name on the top of the list and delete the last name from the bottom of the list! It's that simple and totally legal!*

...entire self-assembling DNA-based organisms. Scientists are working hard on the technology, but research is hampered by a mysterious and poorly understood preliminary stage called "sex".
THANK YOU for your submission of a new
[x] nanostructure
[ ] laser
[ ] transistor
using
[ ] straw and bailing wire
[x] DNA strands
[ ] silicon
This is a bad idea, because
[x] a 3-D structure is difficult to heat-sink
[x] scientists likely never will produce a transistor this way
[ ] this is a case of outright fraud
The problem however is not to make circuits
[ ] out of lasers
[x] 3-D
[x] self ordered
But the problem is to make them
[x] reliably
[x] at low cost
[x] faster

which is primarily a publicity-seeking mag, and not a great peer-reviewed journal for physics.
I can say this because I have a
