Virus builds tissue scaffold

Get genetically-modified, bacteria-infecting viruses to act like a liquid crystal and you could have a way to treat spinal cord injuries. [more]

Rust makes nanocapsules open by remote control

Mix the right two plastics with a sprinkling of rust and you can deliver drugs by turning on a magnetic field. [more]

Light switch controls genes

Attach short strands of RNA to gold nanoparticles and you have a gene-silencing remote control. [more]

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
