Micro backpacks let cells carry loads

Stick a microscopic plastic patch on a living cell and you have a tiny pack mule capable of delivering drugs or imaging agents. [more]

Madeover microbe keeps time

Redesign the genetic network in an E. coli bacteria to make fluorescent proteins blink at regular intervals and you you've made a microbe into a living clock. [more]

Biochip tracks molecular signals

Build a biochip that rapidly injects and captures tiny amounts of chemicals and you have a tool for unlocking medical and biological mysteries. [more]

Nanotube plastic makes cotton smarter

Coat cotton thread with a mix of carbon nanotubes and electrically-conducting plastic and you have a material for making smart clothing and bandages. [more]

Plastic memory gets tough

Cook up a durable plastic that can be switched between high and low electrical conductivity and you have the makings of very inexpensive computer memory that stores data with the power off. [more]

Changes to TRN

"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
