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.
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 ...
Fluid dynamics simulations aim to better predict how air circulating in a hard disk drive
Engineers rely on sophisticated simulation software to understand how air and other fluids flow over objects like an airplane wing or a golf ball. The software typically maps the air and object to a three-dimensional ...
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.
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 ...
Austrian company debuts revolutionary wingless aircraft
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 ...
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.
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 ...
