How smart is your parakeet or that crow in the back yard? Ask Dr. Louis Lefebvre, inventor of the world’s only comprehensive avian IQ index. His intelligence index is not only separating the featherweights from the big bird brains, it’s also providing clues about why some birds make great immigrants, as well as insight into the parallel evolution of primate and bird brains.
The smarts pecking order is based not on a single bird-in-cage test, but on 2,000 reports of feeding innovations that have been observed in the wild and published in the world’s ornithology journals. "Initially, quite honestly, I didn’t think it would work," says Dr. Lefebvre, an animal behaviourist at McGill University in Montreal, Canada, who first reported the bird bell curve system in 1997. "Scientists don’t like anecdotal evidence. So if you’re wary of one anecdote, why would you expect to find a valid pattern in 2,000? I’ve been waiting for something to come up that would invalidate the system, but nothing has."
The biologist, whose work is supported by Science and Engineering Research Canada (NSERC), will present his latest findings at the 2005 American Association for the Advancement of Science meeting in Washington D.C. on February 21.

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...
