Dancing bubbles get the picture
Squeeze
a liquid bubble and you can focus light shining through it. Send sound waves
through the bubble and you can focus a lot faster. [more]
Fungus keeps nanoparticles apart
Grow a fungus in a bunch of metal nanoparticles and you end up with an efficient chemical catalyst. [more]
More cautions on nanoparticles
A pair of studies show that we have a lot to learn about how nanoparticles affect people, animals and the environment. [more]
Electric fields manipulate magnetic memory material
Turn electric fields on in the right places in a magnetic semiconductor and you have the makings of a computer memory that could be built into computer processor chips. [more]
Chipmaking method makes single-electron devices
Stick gold nanoparticles in the right places on vertically-stacked electrodes and you have a route to ultra low-power computer chips. [more]

WATCH August 5th, 2008 The power of perception An item in the current TRN issue about computing via visual perception has me wondering if the method could be adapted to take advantage of one of the great strengths of the human brain: pattern recognition.

| "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 |
