A
robot that previously just walked has now
learned how to run. By focusing on the mathematics
of running, scientists have made a robot that
looks remarkably human-like as it trots around
a laboratory. In addition to contributing
to the design of robots that can stay on their
feet, the work promises to help amputees. Full

DNA
machine links molecules
A DNA nanomachine that stitches together molecules
is a key step toward using DNA to make designer
materials, encrypt information and carry out computations.
The versatile device mimics the protein-building
function of biological cells.
Process
ups biodiesel efficiency
Turning plant matter into liquid fuel is an attractive
alternative to fossil fuels but the process usually
takes a lot of energy. A method that cuts out the
costly distillation step shows promise.
Single
camera measures speed
Giving machines the ability to see is tricky enough
using two cameras and stereo vision. Some nifty
math gives a single camera the ability to track
an object's speed. Speed traps sans radar, anyone?
