Flexible wings driven by simple oscillation may be viable for efficient micro air vehicles
— 23 Nov 2010 17:47 | TechnologyIn the future, tiny air vehicles may be able to fly through cracks in concrete to search for earthquake victims, explore a contaminated building or conduct surveillance missions for…
Miniature auto differential helps tiny aerial robots stay aloft
— 3 Sep 2010 12:01 | TechnologyEngineers at Harvard University have created a millionth-scale automobile differential to govern the flight of minuscule aerial robots that could someday be used to probe environmental…
Artificial butterfly in flight and filmed
— 20 May 2010 12:40 | TechnologyA group of Japanese researchers, who publish their findings today Thursday, 20 May in IOP Publishing's Bioinspiration and Biomimetics, have succeeded in building a fully functional…
Flag has ladies all of a flutter
— 29 Apr 2010 08:49 | BiologyA new study - using high speed video and feathers bought on ebay - shows that when the male snipe sticks out his outer tail feathers, they flutter like flags in the wind, producing…
Secrets of insect flight revealed
— 18 Sep 2009 13:44 | BiologyResearchers are one step closer to creating a micro-aircraft that flies with the manoeuvrability and energy efficiency of an insect after decoding the aerodynamic secrets of insect…
Maple seeds and animals exploit the same trick to fly
— 12 Jun 2009 17:48 | BiologyThe twirling seeds of maple trees spin like miniature helicopters as they fall to the ground. Because the seeds descend slowly as they swirl, they can be carried aloft by the wind and…
World class UK research is behind the fastest car in the world
— 23 Oct 2008 18:00 | TechnologyWorld class UK research is helping to build the fastest car in the world thanks to the Engineering and Physical Sciences Research Council (EPSRC). The BLOODHOUND SSC Project, led by…
MIT solves 100-year-old engineering problem
— 7 Oct 2008 06:24 | TechnologyAs a car accelerates up and down a hill then slows to follow a hairpin turn, the airflow around it cannot keep up and detaches from the vehicle. This aerodynamic separation creates…
Want to fly? Don't copy the birds and the bees
— 6 Jul 2008 18:29 | BiologySince earliest recorded history, and presumably beyond, humans have always wanted to fly. First attempts involved imitation of winged creatures around them, and unfailingly ended in…
