A research group from the University of Oxford has gone one step further: by attaching a compact motion measurement unit in addition to cameras they hope to glean novel information on what it is that makes birds aeronautical experts. Their results could help in designing wing-morphing aircraft that would have deformable wing and tail parts, in place of conventional trailing-edge flaps. Dr Graham Taylor has been testing the system in Denmark on a trained Steppe Eagle and will introduce the technique on Monday 3rd April at the Society for Experimental Biology’s Annual Main Meeting in Canterbury [session A5].
Using this technique allows the researchers to study the flight mechanisms of free-flying birds, which apart from being more informative offers an ethical means of bird flight analysis. Several cameras are mounted on the bird’s back or belly and point at the wings, head and tail. The motion measurement unit weighs less than 50g and provides complete 3-dimensional information on the orientation, rotation and acceleration of the Eagle. The research group want to fit their motion measurements to dynamical models of bird flight to allow them to work out how the Eagle’s control system functions.
Recent trials in Denmark have proved successful. “We can measure tail spread, pitch angle and bank angle from the onboard video directly”, says Taylor. “The plan is to relate these measurable control inputs to the body motion of the bird, which we can quantify using the motion measurement unit.”

Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
