At the Daphnia Genomics Consortiums annual meeting in Bloomington this week, Indiana University and Joint Genome Institute scientists announced theyve completed a "shotgun" sequence for Daphnia pulex, or the water flea, as its better known to high school biology students.
"Daphnia is important to the environmental sciences, where the goal is to understand the complexities of ecosystems by getting a handle on how species in natural settings respond genetically to their environments," said Daphnia Genomics Project leader John Colbourne. "Ecologists and evolutionary biologists would also want to learn more about how genetic variation is important for adaptation and how populations survive in a changing world."

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...

Physics supports biology: Researchers from PTB have developed a model system to investigate friction phenomena with atomic precision
Friction: what you want from car brakes, otherwise rather a nuisance. In any case, it is useful to know as precisely as possible how friction phenomena arise –...
