Papers of Note
Etch a pair of nanoscale pillars in a chip and you have the key ingredient for a light source that promises to boost quantum computing and quantum communications.
Ultrabright source of entangled photon pairs, Nature
Induce the right arrangement of DNA cables and rods and you have the molecular version of architectural components that could be used to make and repair tissue.
Self-assembly of three-dimensional prestressed tensegrity structures from DNA, Nature Nanotechnology
Make liquid crystal out of peptides and you can form artificial scaffolding to interconnect cells, a key requirement for growing organs in the laboratory.

cancer drugs move to the next level: humansA growing number of cancer therapies packaged in infinitesimal particles are making their way to patients.
Can nanotech beat cancer?
Cancer will always be with us in some form, but the fear and devastation it causes could be history within a generation. We'll have the tiniest of things to thank for it.

| "Physics
is to the rest of science what machine tools are to engineering. A
corollary is that science places power in our hands which can be used
for good or ill. Technology has been abused in this way throughout
the ages from gunpowder to atomic bombs." - John Pendry, Imperial College London |
