On Nov. 21 at 07:55 UTC/2:55 a.m. EDT the MODIS or Moderate Resolution Imaging Spectroradiometer instrument that flies aboard NASA's Aqua satellite captured a visible image of Tropical Cyclone Helen that showed clouds in the storm's western quadrant had already spread over eastern India.

Two minutes before the MODIS instrument captured the visible image of Helen's clouds, the infrared instrument aboard Aqua called the Atmospheric Infrared Sounder or AIRS instrument used infrared light to gather data from the storm. The infrared data showed that the strongest thunderstorms with the coldest cloud top temperatures were still off-shore.The stretched around the center from northwest to southwest and wrapped around to the east. Only the bands of thunderstorms in the northern quadrant appeared to be fragmented, which could be a result of that area's interaction with land.
As a result of the strong waves and tropical-storm force winds, warnings are in effect for Andhra Pradesh that include: A storm surge of 1 to 1.5 meters/3.2 to 4.9 feet will occur at the time of landfall, Thatched roofs and huts will sustain damage and a call for fisheries to cease operations.
Helen is expected to weaken as it nears the coast as it moves into cooler waters and continues to battle moderate wind shear. Helen is expected to make landfall near Tenali early on November 22. After landfall, Helen should weaken as it moves west where it is expected to dissipate in a couple of days.

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...
