PAPERS OF NOTE
Manipulate DNA molecules the right way and you've got a simple type of computer programming language.
Molecular implementation of simple logic programs, Nature Nanotechnology
Carry
out 1,024 simultaneous chemical reactions on a biochip and you can create
drugs and other substances from simple building blocks. An integrated microfluidic device for large-scale in situ click chemistry screening, Lab on a Chip
Make a gel that changes shape in response to enzymes and you've got a new way to deliver drugs.
Dynamic, 3D-Pattern Formation Within Enzyme-Responsive Hydrogels, Advanced Materials
Heat up tiny liquid crystal spheres and they turn into cigar-shaped particles, giving you ready-made biochips valves.

WATCH January 14, 2009 Citizen science in the age of connectedness A nice column in the New York Times by biologist Aaron E. Hirsh explains the rise of Big Science massive, centralized projects with large staffs and expensive equipment and the emerging trend of distributed citizen science. [more] |
| "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 |
