In an interview with David Talbot, Technology Review’s chief correspondent, Stephen Wolfram describes what motivated him to launch Wolfram Alpha, how the “knowledge engine” works, and where it’s headed.
The bacteria propel the machine in different directions.
A new climbing robot quickly makes its way up a telephone pole.
This machine developed by researchers from McGill University, in Canada, makes ice sculptures by carefully laying down deposits of ice. Here it begins to build a snowflake sculpture. (The video is shown at five times normal speed.)
Researchers at the German Aerospace Center are studying the impact of collisions between wayward robots and crash-test dummies. They hope to develop effective accident-prevention systems.
In this video, a camera rests atop an ordinary car. Software developed by researchers at ETH Zurich and Toyota rapidly identifies pedestrians and other vehicles.
Robotic cars navigate around a miniature city created by researchers at Boston University while observing traffic rules and avoiding collisions.
This robot, Adelopod, was created by researchers at the University of Minnesota. It tumbles over itself--a simple, low-power way to get around.
Amazon CEO Jeff Bezos demonstrates the Kindle DX at Pace University, in New York City.
Researchers control microscopic magnets individually by manipulating magnetic and electric fields. The magnets could one day be used to assemble microscopic structures or deliver drugs to a cell.
