Shipping companies can route ships more safely and efficiently. Ocean search-and-rescue can operate more effectively. Meteorologists and climatologists now have a tool to provide long-range weather prediction more accurately. Navies too can perform more accurate anti-submarine surveillance. And environmental managers now have a mechanism to track pollution, algal blooms, or emergent situations such as oil spills. And, this is all due to a unique three-dimensional ocean model that has been developed by Rosenstiel School researchers in collaboration with scientists at the Naval Research Laboratory.
Featured in the March issue of Oceanography, the HYbrid Coordinate Ocean Model (HYCOM) is the critical part of data assimilative systems at the Naval Research Laboratory and at NOAA’s National Center for Environmental Prediction. The Navy will tap the velocities, temperature, and salinities of the HYCOM prediction system to force smaller models that provide even higher resolution that can account for things like rivers, tides, etc. in real-time for anywhere in the world. NOAA’s new Real-Time Ocean Forecast System will provide mariners with “nowcasts” and five-day forecasts for the entire North Atlantic Ocean. While other ocean models have been developed in the past, HYCOM is unique not only because it provides three-dimensional, global data that is of fine enough resolution to factor in the real-time displacements in currents caused by eddies, but also because of its flexibility in modeling both coastal and deep ocean regions (http://www.hycom.org). This enhanced understanding of the ocean offers invaluable applications.
“While a computer model may sound rather abstract to non-scientists, it’s exactly what can help clarify forecasting and minimize or prevent impacts from natural hazards on the seas,” said Dr. Eric Chassignet, principal investigator and a Rosenstiel School professor in meteorology and physical oceanography. Chassignet also just published a related book, titled Ocean Weather Forecasting: An Integrated View of Oceanography, which is now available.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
