Almost 150 different genomes have been sequenced to date, including the human genome. But sequencing needs are growing faster than ever: In March 2003, the Bush administration announced it will spend $1 billion over five years to increase forensic analysis of DNA, including a backlog of up to 300,000 samples. And the success of the growing field of genomic medicine, which promises to deliver better therapies and diagnostics, depends on faster sequencing technology.
This fall, researchers at Whitehead Institute will test new technology that could aid these and other endeavors. The BioMEMS 768 Sequencer can sequence the entire human genome in only one year, processing up to 7 million DNA letters a day, about seven times faster than its nearest rival. Scientists began working on the project in 1999 with a $7 million National Human Genome Research Institute grant. The technology eventually will help scientists quickly determine the exact genetic sequence of the DNA of many different organisms, and could lead to faster forensic analysis of DNA gathered in criminal cases.
The heart of the new BioMEMs machine is a large glass chip etched with tiny microchannels called "lanes." It tests 384 lanes of DNA at a time, four times more than existing capillary sequencers. Each lane can accommodate longer strands of DNA: about 850 bases (the nucleic acids found in DNA, abbreviated by the letters A, C, T or G), compared to the current 550 bases per lane.

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.
