Tiny Airplanes Could be the Next Hurricane Hunters

Tiny unmanned craft — some fly, others dart under the waves — are being developed at the University of Florida. They can spy on hurricanes at close range without getting blown willy-nilly, while sensors onboard collect and send in real time the data scientists need to predict the intensity...

Robot Runs Like a Cat

Thanks to its legs, whose design faithfully reproduces feline morphology, EPFL’s four-legged “cheetah-cub robot” has the same advantages as its model: It is small, light and fast. Still in its experimental stage, the robot will serve as a platform for research in locomotion and biomechanics.

Researchers Develop Microfluidic Test-Bed for Solar Systems

Solar technologies must convert solar energy into electrochemical energy efficiently and on a massive scale. A key to meeting this challenge may lie in the ability to test such energy conversion schemes on the micro-scale.

Researchers Print Artificial Bone

While researchers have come up with hierarchical structures in the design of new materials, going from a computer model to the production of physical artifacts has been a persistent challenge. Hierarchical structures that give natural composites their strength are self-assembled through electrochemical...

Array Measures Vibrations Across Skin

In the near future, a buzz in your belt or a pulse from your jacket may give you instructions on how to navigate your surroundings. Think of it as tactile Morse code: vibrations from a wearable, GPS-linked device that tell you to turn right or left, or stop, depending on the pattern of pulses you feel. Such...

Question of the Week
Will Users Adopt 3D TV?

ESPN, which in 2010 announced that it would offer sporting events like World Cup soccer and the NCAA national championship football game in 3-D, now says it will stop doing so this year. Now that the sports giant, one of 3-D TV's initial champions, is abandoning the format, many are wondering if the 3D experiment is...
