Scientists in sunny, hot Florida are thinking cold thoughts since they added ozone measurements from a NASA satellite into computer weather forecast models and improved several factors in a forecast of a major winter snowstorm that hit the United States in 2000.
When scientists added ozone measurements, predictions of snowstorm intensity, snowfall amounts and the storm track all improved for a storm that hit Washington, D.C. As such, they may be able to do the same for future storms, according to a study published in a recent issue of the American Meteorological Societys Journal of Applied Meteorology.
Kun-Il Jang and Xiaolei Zou, research scientists from Florida State University, used data from NASAs Earth Probe/Total Ozone Mapping Spectrometer (TOMS) satellite to create a more accurate prediction of a January 2000 snowstorm in the Washington metropolitan area. Other researchers included Mel Shapiro of the National Oceanic and Atmospheric Administration’s (NOAA) Environmental Technology Laboratory (ETL), Manuel Pondeca of NOAA’s National Center for Environmental Prediction (NCEP), C. Davis of the National Center for Atmospheric Research (NCAR), Boulder, Colo., and A. Krueger of the University of Maryland, Baltimore County.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
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...
