With the genomes of humans and several insects, animals and crop plants mapped or sequenced, biologists are turning their attention to single-celled algae no thicker than a human hair. Among the possible payoffs: crops requiring less fertilizer, a source of renewable energy and a new source for novel proteins.
The algae, Chlamydomonas reinhardtii , already are an important biological model for genetics research. Now, the complete genome of the plant’s chloroplast has been sequenced by scientists at the Boyce Thompson Institute (BTI) for Plant Research located on the campus of Cornell University. The chloroplast is the area of the plant that harvests light energy. Details of the sequencing (that is, determining the base sequence of each of the ordered DNA fragments) appear in the latest issue of the journal The Plant Cell (November 2002).
The complete chloroplast genome sequence, says David Stern, a biologist and vice president for research at BTI, a not-for-profit research organization, has made it possible to test the response of Chlamydomonas (pronounced CLAMMY-doe-moan-us) to various environmental stresses, work that is reported in an accompanying article in The Plant Cell . In addition, the organism’s nuclear genome is being sequenced by the Joint Genome Institute, a unit of the Department of Energy.

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...
