Tendons, such as the Achilles, connect muscle to bone, and are loaded repeatedly during movement. When exposed to particularly high loads, this can cause injury in some individuals. The risk of injury increases with age, but scientists have never fully understood why.
Tendon injury is common in horses as well as humans, and the team, working together with scientists from the University of Liverpool, University College London and the University of East Anglia, used tendons from horses already deceased to understand injury risk, and demonstrate the mechanism in action.
The research team found that fascicles – the subunit that makes up tendons – are coiled like a spring, or helix. They have shown that the helix structure enables tendons to stretch and recover, with results suggesting that damage to the helix stops the tendon working properly.
“The helical shape of the fascicles seems to be critical in maintaining tendon elasticity,” explains co-author Dr Hazel Screen, a Reader in medical engineering at Queen Mary’s School of Engineering and Materials Science.“Repetitive loading causes the fascicles to unwind and be less effective, triggering them to become damaged or leading to injury.”
The team also showed how ageing affects the helix.

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...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
