Shown here are heart-muscle cells grown in a dish. Sodium rushing into the cells coincides with contraction (as happens during a normal heartbeat) and modulates the sensors’ fluorescence.
This video illustrates Geron’s, a California based cell therapy company, embryonic stem cell therapy for spinal cord injury in rats. The company has received clearance from the US FDA to begin clinical trials.
A prototype electronic musical instrument called “BeatBearing” makes drum patterns using ball bearings.
A tiny bioinspired boat is powered by the surface tension of water as seen in this video. The second half of the video shows the rudder capability.
Researchers have bigger plans for multi-touch screens than the novel interface on Apple's iPhone.
New visualization software makes viewing and interacting with enormous data sets more practical.
A modified 3-D game controller helps improve fine motor control.
Donor hearts could make good scaffolding for new organs.
An MRI imager that is 100 million times more powerful could create 3-D images of viruses.
Researchers use magnets to navigate a microgripping “hand” through a coiled tube and to guide it to a dyed bead and a cell mass. The grippers can be actuated to close like a fist around an object by biochemical cues or by an increase in temperature, the means used to make the hand grip the blue bead and the cell mass in these videos.
