Without destroying endangered freshwater mussels
In the early 1900s, there were 42 species of freshwater mussels in the North Fork of the Holston River in Southwest Virginia. There were 33 downstream of Saltville. Now there are only nine species of mussels downstream of Saltville, and none directly below Saltville. When Virginia Tech geosciences student Megan Brown of Colonial Heights, Va., decided to study the local extinctions of these creatures, some of which have been known to live 200 years and many of which are endangered species, she didnt want to have to use the traditional means of pulverizing them to measure chemical uptake.
At the joint meeting of the Northeastern and Southeastern Sections of the Geological Society of America, Brown will report on her non-invasive means to determine whether pollution or environmental stresses are threatening freshwater mussels. The GSA meeting is March 25-27 in Tysons Corner, Va.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
