The team led by Stanislav Gorb used optical sensors to measure the forces applied by each leg of a fly whilst walking freely on a smooth ceiling. They found that the best attachment force occurred when at least one leg from each side of the fly’s body was in contact with the surface. These principles were then proven using artificial polymer tape to simulate the adhesive pads found on the feet of insects.

“Walking on a ceiling is very different from normal walking because the gravity tends to pull an inverted insect away instead of pressing it to the surface”, explains Dr Gorb. “Our results, in combination with the knowledge on the microstructure of pads, provide important inspiration for mimicking locomotion of wall and ceiling walking machines, which use micropatterned polymer feet for generating adhesion”.
Dr Gorb will be presenting his results at the Annual Meeting of the Society for Experimental Biology on Wednesday 5th April [session A7].

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...
