For the first time since 1960, US scientists will be able to explore the deepest parts of the world’s oceans, up to seven miles below the surface, with a novel underwater vehicle capable of performing multiple tasks in extreme conditions. Researchers at the Woods Hole Oceanographic Institution (WHOI) are developing a battery-powered underwater robot to enable scientists to explore the ocean’s most remote regions up to 11,000 meters (36,000-feet) deep.
The hybrid remotely operated vehicle, or HROV, will be able to operate in two modes: as an autonomous, or free-swimming, vehicle for wide area surveys, and as a tethered, or cabled, vehicle for close-up sampling and other tasks. In the latter mode, it will use a novel fiber optic micro cable only one thirty-second of an inch thick, a major departure from the large heavy cables typically used with tethered vehicles. The deep-sea vehicle will require new technologies such as ceramic housings for cameras and other electronic equipment to withstand the pressures at the vehicle’s extreme operating depths.
Funding for the four-year, $5-million HROV project is provided by the National Science Foundation, with additional support from the US Navy and the National Oceanic and Atmospheric Administration. Principal investigators are Andrew Bowen and Dana Yoerger of WHOI’s Deep Submergence Laboratory (DSL) in the Applied Ocean Physics and Engineering Department and Louis Whitcomb, an Associate Professor in the Department of Mechanical Engineering at Johns Hopkins University. Whitcomb is also a visiting investigator in DSL. The new vehicle will undergo initial trails in three years.

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...
