Research cruise provides new information on tsunami during survey of remote area
A summer voyage to investigate the causes of one of the most devastating tsunamis in United States history has uncovered new mysteries about biological and geological processes off Alaska. Probing the depths below one of the worlds most important fisheries, scientists with Scripps Institution of Oceanography at the University of California, San Diego, as well as Indiana State University and their colleagues, conducted the first exploration of deep seafloor biological communities in a sector of the Alaskan margin off the Aleutian Islands along the northern part of the Pacific Rim.
In addition to identifying previously undiscovered deep-sea habitats, the researchers have stirred debate about the causes and characteristics of a devastating 1946 tsunami. The Pacific Ocean-wide event led to more than 150 deaths and widespread destruction as it pounded shorelines from Alaska to Antarctica. The July research cruise, aboard the Scripps research vessel Roger Revelle, was sponsored by the National Oceanic and Atmospheric Administrations West Coast National Undersea Research Program.

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...
