Variable camber airfoil: New concept, new challenge
A variable camber airfoil is an airfoil that changes camber to maximize its performance under radically different flight conditions. Little attention has been paid to the history of flow evolvement due to the camber deformation. In the 42nd issue of SCIENTIA SINICA, a paper distinguished the aerodynamic characteristics of a variable camber airfoil for steady and quasi-steady flow separation behaviors. Such distinction presents a new challenge to aircraft design. (2012-06-20)

Virgin male moths think they're hot when they're not
Talk about throwing yourself into a relationship too soon. A University of Utah study found that when a virgin male moth gets a whiff of female sex attractant, he's quicker to start shivering to warm up his flight muscles, and then takes off prematurely when he's still too cool for powerful flight. So his headlong rush to reach the female first may cost him the race. (2012-06-07)

Mosquitoes fly in rain thanks to low mass
Even though a single raindrop can weigh 50 times more than a mosquito, the insect is still able to fly through a downpour. Georgia Tech researchers used high-speed videography to see how the mosquito's strong exoskeleton and low mass render it impervious to falling rain drops. (2012-06-04)
