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.”

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
