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.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
