As Hurricane Ophelia is set to make landfall on the North Carolina coast on Wednesday or Thursday (Sept. 14 or 15), analysis techniques developed by researchers at the University of Wisconsin-Madison Tropical Cyclones group in the Cooperative Institute for Meteorological Satellite Studies are helping to predict the anticipated path of the storm.
Since 1982, the Tropical Cyclones group has been developing specialized tools used by forecasters with weather satellite data using its Man computer Interactive Data Access System (McIDAS). The group forges techniques of use to forecasters, and for any major tropical storm its Web site transfers large amounts of data to researchers, forecasters and the general public. (During Hurricane Katrina, the site experienced 1.8 million hits.)
Most of its work is done far ahead of an actual hurricane, according to team leader Chris Velden, providing online analyses and imagery to forecasters long before storms reach land using the resources of the Data Center of the UW-Madison Space Science and Engineering Center. After using Tropical Cyclone group products during Hurricane Katrina, National Hurricane Center Director Max Mayfield noted that CIMSS imagery and products would see much future use.

Species Richness – a false friend? Scientists want to improve biodiversity assessments

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
