NASA’s mars exploration rover, Opportunity, has trekked the surface of the Red Planet for five years. It discovered the first signs of ancient ice and is helping to answer the question: Is there life on Mars?
Researchers at Indiana University lead by Alessandro Vespignani have created a mathematical model that shows how people using a Wi-Fi wireless internet connection are targets for infection.
Researchers at MIT have developed a computer model that simulates the dynamics of blood flowing around a drug-eluting stent. This allows them to evaluate how the drug is released and distributed over time in the arterial wall.
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.
A modified 3-D game controller helps improve fine motor control.
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.
