A Duke University study has found that maturing stands of pines exposed to the higher levels of carbon dioxide expected by mid-century produce more needles than those absorbing todays levels of the gas, even under drought conditions. However, the study also found that lack of soil nutrients may impose limitations in many forests.
Duke graduate student Heather McCarthy will describe results she obtained from a futuristic open-air experimental forest site at 8 a.m. Eastern Time on Thursday, Aug. 11, 2005 during the 2005 annual meeting of the Ecological Society of America in Montreal.
Her work was supported by the United States Department of Energy and the U.S. Department of Agricultures Forest Service.

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...
