Nano-nasties

Frank Chen, a researcher at the Lawrence Berkeley National Laboratory, has developed a way to predict and evaluate the effects of exposure to a particular nanomaterial on human skin cells.. Once the skin cells have been exposed, Chen uses computerised image analysis ...

Invention: Aerodynamic 'bellyflaps'

Aerodynamic 'bellyflaps' Blended wing aircraft - streamlined planes with a fuselage blended together with the wings to form one whole - have significant advantages over conventional planes. Ron Blackwelder, an aerospace engineer at the University of Southern California in Los Angeles, US, suggests adding ...
