Cornell University researchers will present new audio evidence supporting the existence of the phantomlike ivory-billed woodpecker Aug. 24 and 25 at the 123rd American Ornithologists Union meeting in Santa Barbara, Calif.
Cornell Lab of Ornithology researcher Russ Charif will begin presenting the new audio evidence at 10:30 a.m. PST Aug. 24 in Lotte Lehmann Hall at the University of California-Santa Barbara (UCSB). Lab members Ron Rohrbaugh and Ken Rosenberg and Director John Fitzpatrick will also make presentations.
One recording suggests the presence of at least two birds: a signature double rap that sounds like an ivory-billed woodpecker drumming on a tree from a distance followed by a closer double rap. This drumming behavior is typical of many large woodpeckers closely related with the ivory-bill. Other recordings include sounds that resemble the ivory-billed woodpeckers distinctively nasal "kent" calls. The sounds were discovered by Cornell audio experts combing through 17,000 hours of audio files from autonomous recording units installed in the Arkansas woods and swamplands.

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...
