(PhysOrg.com) -- Even if you are not a cook, you might have wondered why a pinch of flour (or any small particles) thrown into a bowl of water will disperse in a dramatic fashion, radiating outward as if it was exploding. Pushpendra Singh, PhD, a mechanical engineering professor at NJIT who has studied and written about the phenomenon, has not only thought about it, but can explain why. http://www.physorg.com/news177616622.html Physics Mon, 16 Nov 2009 18:30:05 EST news177616622 New research shows some bees brace themselves against wind and turbulence by extending their sturdy hind legs while flying. But this approach comes at a steep cost, increasing aerodynamic drag and the power required for flight by roughly 30 percent, and cutting into the bees' flight performance. http://www.physorg.com/news163161417.html Biology Tue, 02 Jun 2009 11:37:43 EST news163161417 (PhysOrg.com) -- From Leonardo da Vinci to the Greek tragedy of Icarus, birds have emboldened scientific minds to master flight. Now, Stanford researchers can be added to the list of ornithologically inspired innovators. http://www.physorg.com/news163092004.html Technology Mon, 01 Jun 2009 16:20:46 EST news163092004 (PhysOrg.com) -- ESA's gravity mission GOCE has achieved a first in the history of satellite technology. The sophisticated electric propulsion system has shown that it is able to keep the satellite completely free from drag as it cuts through the remnants of Earth's atmosphere - paving the way for the best gravity data ever. http://www.physorg.com/news162565775.html Space & Earth Tue, 26 May 2009 14:10:04 EST news162565775 GOCE's highly sensitive gradiometer instrument has been switched on and is producing data. Forming the heart of GOCE, the gradiometer is specifically designed to measure Earth's gravity field with unprecedented accuracy. http://www.physorg.com/news158420681.html Space & Earth Wed, 08 Apr 2009 14:45:20 EST news158420681 It is commonly known that racing cars and bicyclists can reduce air resistance by following closely behind a leader, but researchers from New York University and Cornell University have found the opposite is true with flapping objects, such as flags. http://www.physorg.com/news145543783.html Physics Mon, 10 Nov 2008 12:49:43 EST news145543783 As if the drivers of mini vans and utility vehicles needed any more encouragement to drive fast between jobs, US researchers have designed a new rear spoiler for bluff-backed vehicles that can reduce drag and lift significantly. Writing in the International Journal of Vehicle Design, the team describes how the new spoiler could improve fuel consumption as well as vehicle handling. http://www.physorg.com/news145535595.html Technology Mon, 10 Nov 2008 10:33:15 EST news145535595 (PhysOrg.com) -- Swimmers from around the world are setting world and Olympic records in Beijing this month and most are doing it wearing a swimsuit made of fabric tested at NASA. http://www.physorg.com/news138286404.html Physics Mon, 18 Aug 2008 13:53:24 EST news138286404 Swimmers around the world are breaking records this year like never before, including at this week's U.S. Olympic trials. Some attribute it to extensive training as athletes prepare to compete at this summer's games in Beijing. Others say one factor may be a new swimsuit ... a space-age swimsuit made of fabric tested at NASA. http://www.physorg.com/news134058519.html Physics Mon, 30 Jun 2008 15:28:39 EST news134058519 "Hold your hands out to the sun. What do you feel? Heat, of course. But there's pressure as well - though you've never noticed it, because it's so tiny. Over the area of your hands, it only comes to about a millionth of an ounce. But out in space, even a pressure as small as that can be important - for it's acting all the time, hour after hour, day after day. Unlike rocket fuel, it's free and unlimited. If we want to, we can use it; we can build sails to catch the radiation blowing from the sun." http://www.physorg.com/news133794632.html Space & Earth Fri, 27 Jun 2008 14:10:32 EST news133794632
