One of the worlds largest freshwater fish, an Asian catfish as big as a bear, may disappear in the near future, warns a UC Davis conservation biologist from his research base in Cambodia.
The giant catfish (Pangasianodon gigas), which grows to 10 feet long and 650 pounds, is a migratory species in the rivers of Thailand, Cambodia and Laos. It has been a mainstay for local fishers for centuries.
Now very few fish are being caught. At one typical traditional fishing spot on the Mekong River at Chiang Khong, Thailand, 30 fish were caught in 1995, seven in 1997, two in 1998 and none in 2000 and 2001.

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...
