Research to improve the resistance of Australias northern beef herds to cattle ticks received a boost recently with the discovery that tropically-adapted cattle breeds have a different immune response to tick infestation than more susceptible European breeds.
CSIRO Livestock Industries scientist, Dr Ian Sutherland, says that while research has traditionally focused on the genetics of tick resistance, little was known about the underlying immune mechanisms involved.
Now, however, Dr Sutherlands parasitology team in Rockhampton has found that tropically-adapted (Bos indicus) cattle, such as Brahmans, which are known for their high tolerance to cattle ticks (Boophilus microplus), switch off parts of their immune system in response to tick infestation.

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...
