Sound-altered light promises speedier chips
Lightwaves usually contain many slightly different wavelengths.
Use a soundwave to spread the wavelengths and you get microscopic parallel
lines of dark and light... [more]Lasers switch on drugs
A drug that's activated when its molecules are hit by two photons simultaneously makes it possible to precisely control where in the body the drug takes effect. [more]
Nanoparticles take new angles on cancer
A pair of nanoparticle-based drugs embody new approaches to cancer treatment. The first uses a combination of magnetic nanoparticles and biological molecules... [more]
Shape memory boosts biochips
Shape-memory alloys are bits of metal that reversibly change shape. They can be made into tiny valves, pumps and latches... [more]
3D biochips make cells at home
A biochip harboring hydrogels makes it possible to study cells in a more lifelike three-dimensional environment. [more]
Paired mirrors lower display power
A variation on the micromirror arrays used in some large-screen televisions promises more efficient computer displays. [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 |
