New approach assembles big structures from small interlocking pieces
MIT researchers have developed a lightweight structure whose tiny blocks can be snapped together much like the bricks of a child's construction toy. The new material, the researchers say, could revolutionize ...
Fluorescent nanotube coating can detect strain
A new type of paint made with carbon nanotubes at Rice University can help detect strain in buildings, bridges and airplanes.

Austrian company debuts revolutionary wingless aircraft
Engineers gain insight into turbulence formation and evolution in fluids
in the patterns that natural gas makes as it swirls through a transcontinental pipeline or in the drag that occurs as a plane soars through the sky. Reducing such turbulence on say, an airplane wing, would ...
Polymer science team designs new nanotech technique for lower-cost materials repair
(PhysOrg.com) -- In the super-small world of nanostructures, a team of polymer scientists and engineers at the University of Massachusetts Amherst have discovered how to make nano-scale repairs to a damaged ...
NASA investigates use of 'trailblazing' material for new sensors
Tiny sensors—made of a potentially trailblazing material just one atom thick and heralded as the "next best thing" since the invention of silicon—are now being developed to detect trace elements in Earth's ...
Winter Olympics Science Notes: Ski Jumping
The first gold medal of the 2010 Vancouver Winter Olympics went to Switzerland's Simon Ammann, who won the normal hill ski jumping competition on Feb. 13 with a top jump of 108 meters -- nearly the length ...
Terrifying pterosaurs were fragile in flight
Pterosaurs, the largest creatures ever to take to the skies, were adept fliers in a balmy breeze but would have crashed in stormy weather, according to a study published Wednesday.
Getting ice, frost off planes problematic
The buildup of ice on surfaces can cause problems in many situations: On airplane wings or on their engine turbine blades, ice can both add weight and interfere with a wings lift, which can make it impossible ...
Explained: Hydrophobic and hydrophilic
Sometimes water spreads evenly when it hits a surface; sometimes it beads into tiny droplets. While people have noticed these differences since ancient times, a better understanding of these properties, and ...
Triangles Go Underwater and Supersonic
(PhysOrg.com) -- The seemingly effortless way dolphins and porpoises slice through the water and the unique capabilities of the supersonic Concorde airplane have more in common than one might think.
High winds affect ocean circulation in North Atlantic, says study
(Phys.org)—Gale-force winds that whip around the Greenland coast are driving ocean circulation, confirms a new study on the cover of the Nov. 30 issue of Geophysical Research Letters.
