The software now lets users dive miles beneath the ocean waves.
Scientists at Carnegie Mellon have engineered a snakelike robotic arm that can monitor health signs and potentially administer treatments. The robot is equipped with sensors and a small camera, which wirelessly relays video to a laptop. A researcher watches the video onscreen and wirelessly controls the robot’s movements with a joystick. The robot can move anywhere along the length of the body, and can lower itself to administer oxygen or monitor a person’s breathing.
A scientist sends a wireless signal from the laptop to the beetle to start and then stop flight. The beetle, seen in the upper part of the frame, is tethered for practical purposes. The insect is attached to a clear plate, so that its flight pattern can be better observed. An oscilloscope shows the electrical signals as they are delivered: a short oscillating pulse triggers the animal to flap its wings, and it continues flapping until a short single pulse tells it to stop.
NASA’s mars exploration rover, Spirit, has explored the Red Planet for half a decade, overcoming technical challenges and making significant discoveries.
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.
