A new microscopy technique called iPALM has been used to reveal structures within cells. Fluorescent labels have been attached to integrins, proteins that cells use to attach to surfaces. The yellow and red regions depict areas where the cell has used integrins to attach to a glass surface. The blue and purple regions are networks of integrins inside a cell.
A new human-powered generator tries to capture walking energy.
A new material allows researchers to write and erase 3-D images for displays.
Startup ZINK Imaging is giving inkless printing a new look.
A treatment that shrinks gaps in the mucus membrane might protect caregivers during an influenza outbreak.
NASA's newest exploration rover, dubbed Axel for its design, can climb steep and rocky terrain and explore deep craters on planets like Mars. It uses only three actuators to operate upside down, right side up, turn in place, and follow illogical paths. Axel can maneuver autonomously using cameras, sensors, and wireless communication, or be tethered to a larger spacecraft.
A supersonic bullet is fired with a record-breaking 10 megajoules of muzzle energy.
A new tool could help people organize information from Web searches.
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.
The software now lets users dive miles beneath the ocean waves.
