Expedition to help protect Floridas unique oculina deepwater reefs
On Wednesday, Oct. 12, 2005, scientists will begin a six-day expedition to explore one of Floridas most vital but least familiar marine resources--the spectacular deepwater coral reefs of the Oculina Bank--some 30 years after their discovery. Among the teams goals is the start of a sustained and critically needed monitoring program to complement , and evaluate the effectiveness of, stricter regulations and enforcement activities in the area. The group will also be exploring new portions of the reef revealed by a recently developed high-resolution seafloor map.
The Oculina reefs, in depths from 250 to 300 feet, were built over the past thousand years or so by the delicate ivory tree coral Oculina varicosa, and include a series of spectacular pinnacles, mounds, and ridges that can grow up to100 feet high. Deepwater Oculina reefs are not known to exist anywhere else on the planet besides off Florida.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...

For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel’s Swiss Nanoscience Institute network have reported the results in the journal Science Advances.
Hydrogen is the most common element in the universe and is an integral part of almost all organic compounds. Molecules and sections of macromolecules are...
