Historical study shows elevated aridity in periods of warming
Severe drought in western states in recent years may be linked to climate warming trends, according to new research led by scientists from the Lamont-Doherty Earth Observatory of Columbia University to be posted October 7 on Science magazines website, www.sciencemag.org. This research was supported by the National Oceanic and Atmospheric Administration (NOAA) and the National Science Foundation (NSF).
Analyzing aridity in the western U.S. over the past 1,200 years, the study team, which also included scientists from the University of Arizona, University of Arkansas, and NOAA, found evidence suggesting that elevated aridity in the U.S. West may be a natural response to climate warming. "The Western United States is so vulnerable to drought, we thought it was important to understand some of the long-term causes of drought in North America," said lead author Dr. Edward R. Cook of the Lamont Doherty Earth Observatorys tree ring laboratory.

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...

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...
