Which flu did you get? TIGR scientists survey five New York flu seasons
On the eve of the 2005-06 flu season, scientists at The Institute for Genomic Research (TIGR) have captured influenza evolution in action. In a study published in this weeks journal Nature, the researchers report the first large-scale project to sequence the influenza virus. The study offers a unique snapshot of the rapidly evolving flu virus in a human population--and a new strategy for surveillance.
In the study, TIGR scientists and their colleagues sequenced 209 complete genomes of the human influenza A virus. The genomes represent virus samples, or isolates, taken from patients who visited county clinics across New York over the past five flu seasons, from 1999-2004. Almost all the influenza genomes represent the H3N2 strain, which predominated during these flu seasons. Comparing these genomes, the researchers tracked the changing virus as it moved across the region.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
