DNA builds by design
Heat
up the right DNA strands and let them cool slowly, and you're a step closer
to growing complicated objects in a test tube. [more]

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 |
