Nanoscale polymer capsules could one day be used to deliver chemotherapy direct to tumours, leaving adjacent tissue unscathed. The capsules would be designed to rupture when heated by a low-energy laser pulse, delivering their payload right where it is needed.

A new project from Nasa and three Mexican universities will grow trees on Mars.
The Earth Formation in Mars Project will plant a special type of tree on the red planet that grows on the highest mountain of Mexico, Orizaba Peak.
Nacional Autonoma University of Mexico, Veracruzana University, Veracruz University and Nasa have been researching the trees for years.
Because of the high places they grow - with little oxygen and extreme cold - they are thought to be ideal for the project.
Researcher Luiz Cruz Kuri told Clarin newspaper: "Orizaba Peak has the highest line of trees in the world. We can take then to Mars."
