Nanotubes turn stem cells to bone

Make a surface of the right size nanotubes and you can make stem cells turn into bone cells.[more]

Biochip lights up DNA

Add a photodetector to a biochip and you have an inexpensive medical test that spots subtle differences in DNA.[more]

Nanowires make drugs stick

Coat microscopic beads with nanowires and you've got a better nasal spray.[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
