The final stretch of the Scott Dunn Polar Challenge is approaching: 44 competitors on 16 teams from all over Britain and Ireland are racing on skis, pulling sledges to the 500-kilometre-distant Magnetic North Pole. In this extreme environment, radar ice images from ESAs Envisat help ensure competitors keep safe.
After a year in training, participants set up from Resolute Bay in Canada on Saturday 23 April – the start having been delayed a day by a blizzard. Expected to take about two and a half weeks maximum, the race is the largest high Arctic event of all time, and an exercise in endurance for those taking part.
The Scott Dunn Polar Challenge route runs over both land and sea ice. At this time of year the sunlight is unceasing even as racers make their way through areas where temperatures regularly drop to -50°C.

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...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
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...
