Researchers build a tougher, lighter wind turbine blade

Efforts to build larger wind turbines able to capture more energy from the air are stymied by the weight of blades. A Case Western Reserve University researcher has built a prototype blade that is substantially lighter and ...

New biosensor is based on a nanowire crystal array

(PhysOrg.com) -- A quick, inexpensive and highly sensitive test that identifies disease markers or other molecules in low-concentration solutions could be the result of a Cornell-developed nanomechanical biosensor, which ...

New microchip sorts white blood cells from whole blood

Early in 2012, MIT scientists reported on the development of a postage stamp-sized microchip capable of sorting cells through a technique, known as cell rolling, that mimics a natural mechanism in the body. The device successfully ...

New commercial supply ship reaches space station (Update)

NASA's newest delivery service made its first-ever shipment to the International Space Station on Sunday, another triumph for the booming commercial space arena that has its sights set on launching astronauts.

How microscopic machines can fail in the blink of an eye

How long can tiny gears and other microscopic moving parts last before they wear out? What are the warning signs that these components are about to fail, which can happen in just a few tenths of a second? Striving to provide ...

Study determines best arrangement of tidal sails device

In the long sprint to find new sources of clean, low-cost power, slow and steady might win the raceā€”the slow-moving water of currents and tides, that is. Just as wind turbines tap into the energy of flowing air to generate ...
