A new gamma-ray spectroscope detects the veins of gold, platinum, and rare earths hidden within the asteroids, moons, and other airless objects floating around the solar system. The sensor, developed by teams at Vanderbilt and Fisk Universities, NASA’s Jet Propulsion Laboratory, and the...

A team at the Massachusetts Institute of Technology (MIT) has come up with an innovative approach that, unlike most traditional desalination systems, does not separate ions or water molecules with filters, which can become clogged, or boiling, which consumes great amounts of energy.

A new computerized tool guides stakeholders in preparing for, and recovering from, natural and man-made disasters such as the cyclones in India that knocked out swaths of the Indian Railways Network. The method, developed by Northeastern University researchers, guides stake­holders in the...

A Florida State University researcher has discovered an artificial material that mimics photosynthesis and potentially creates a sustainable energy source. The new material efficiently captures sunlight; then, the energy can be used to break down water into oxygen (O2) and hydrogen (H2).

Despite recent advances in materials design, alternative metals still pose a challenge to manufacturers in practice. Many are considered un-weldable by traditional means, in part because high heat and re-solidification weaken the metals. Engineers at The Ohio State University have developed a new welding technique...

The ATRIAS robot model developed at Oregon State University uses a "spring-mass" walking approach. The natural-gait method gives human-sized bipedal robots the ability to blindly react to rough terrain, maintain balance, retain an efficiency of motion, and walk like humans.

Scientists from The Langevin Institute, Paris, France, have constructed a new fingerprint imaging system that peers inside the finger to take a picture — a more reliable and secure way of identifying individuals. The fingerprint sensor, based on full field optical coherence tomography (FF-OCT), uses an...

Using an air-fluidized bed trackway filled with poppy seeds or glass spheres, researchers at the Georgia Institute of Technology systematically varied the stiffness of the ground to mimic a variety of surfaces, from hard-packed sand to powdery snow. By studying how running lizards, geckos, crabs, and a robot...

For nearly two years, residents of the remote Mexican village of La Mancalona, most of whom are subsistence farmers, have operated and maintained a solar-powered water purification system engineered by researchers at the Massachusetts Institute of Technology (MIT).
