How solar-thermal energy could trim coal plants’ carbon footprint.
An animated fly-through shows the major components of a new zero-emissions, zero-waste city being built in the Middle East.
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.
