Hurricanes can completely re-structure themselves inside, and that presents forecasters with great uncertainty when predicting their effects on the general population.
Recently, scientists used data from NASA’s Tropical Rainfall Measuring Mission (TRMM) satellite to analyze transformations that take place inside a hurricane. Stephen Guimond, a graduate research assistant at Florida State University, Tallahassee, Fla., lead a study that used TRMM data to view the height at which ice melts near the core of several tropical cyclones (the generic name for hurricanes or tropical storms), including Hurricane Ophelia in 2005.
“The temperature structure of a tropical cyclone is directly related to a storm’s wind speed and rainfall, which indirectly affects the storm surge,” Guimond said. It is important to monitor a storm’s thermal structure because this information assists meteorologists in estimating the impact on threatened areas of high winds, flash flooding and large storm surge.

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.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...

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...
