A Science article published on July 9, 2010, describes the discovery of an alternative form of evolution that helps Drosophila flies conquer nematodes that sterilize them. Nematodes are among the most abundant, diverse and destructive parasites of plants and animals.
The article, titled, "Adaptation via Symbiosis; Recent Spread of a Drosophila Defensive Symbiont", is by John Jaenike of the University of Rochester and his colleagues. In a video interview, Jaenike explains the results of this study and their implications for developing treatments for serious human diseases, including river blindness, caused by nematodes; about 17.7 million people worldwide are currently infected with river blindness.
"The protection of an insect from a potent nematode parasite by a bacterial infection is of potential importance in both medicine and agriculture," says George Gilchrist, a program director at the National Science Foundation. "This study adds a new page to the catalogue of interactions between animals and bacteria."
The Science study is also discussed in a press release from the University of Rochester.

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...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
