Optimum inertial self-propulsion design for snowman-like nanorobot
Scale plays a major role in locomotion. Swimming microorganisms, such as bacteria and spermatozoa, are subjected to relatively small inertial forces compared to the viscous forces exerted by the surrounding fluid. Such low-level ...
A smart wristband for nocturnal cyclists
Five EPFL PhD students have developed a wristband that flashes when the rider reaches out to indicate a turn. Their invention was recognized at a European competition.
IHEP in China has ambitions for Higgs factory
New approach to form non-equilibrium structures
Although most natural and synthetic processes prefer to settle into equilibrium—a state of unchanging balance without potential or energy—it is within the realm of non-equilibrium conditions where new possibilities lie. ...
A tree may have the answers to renewable energy
Through an energy conversion process that mimics that of a tree, a University of Wisconsin-Madison materials scientist is making strides in renewable energy technologies for producing hydrogen.
NASA's Chandra X-ray Observatory celebrates 15th anniversary
Fifteen years ago, NASA's Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia. Since its deployment on July 23, 1999, Chandra has helped revolutionize our understanding of ...
Study shows how to power California with wind, water and sun
Imagine a smog-free Los Angeles, where electric cars ply silent freeways, solar panels blanket rooftops and power plants run on heat from beneath the earth, from howling winds and from the blazing desert sun.
Google offers big prize for small power box
Google is offering a million-dollar prize for a breakthrough that would make solar or wind generated electricity more enticing for everyday uses.
Engineers recall five-year planning for nation's largest federally owned wind project
Within the world of wind power, Kurt Myers and his engineering team are like Swiss Army knives in a silverware drawer. In his career as a wind energy systems expert, Myers has become a leading consultant ...
