NASA-NOAA's Suomi NPP satellite saw that Tropical Cyclone Winston maintained a pinhole eye as it tracked east of southern Vanuatu's islands in the Southern Pacific Ocean on Feb. 23, 2016. Infrared imagery showed bands of strong thunderstorms were wrapping into the low-level center of the storm.
On Feb. 23, 2016 at 0140 UTC (Feb. 22, 2016 at 8:40 p.m. EST) the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard NASA-NOAA's Suomi NPP satellite captured a visible image of Tropical Cyclone Winston that showed a pinhole eye as it was moving east of Vanuatu's southernmost islands.
Animated enhanced infrared satellite imagery indicated a slowly-decaying low-level circulation center with curved strong bands of thunderstorms wrapping into the center of the storm.
The Atmospheric Infrared Sounder or AIRS instrument that flies aboard NASA's Aqua satellite provided infrared temperature data on the system on Feb. 23, 2016 at 01:53 UTC (Feb. 22, 2016 at 8:53 p.m. EST).
Some cloud top temperatures were colder than minus 63 Fahrenheit/ minus 53 Celsius, indicating they were high into the troposphere. Cloud top temperatures that cold have shown that those storms can produce heavy rainfall
Joint Typhoon Warning Center (JTWC) said that at 1500 GMT (10 a.m. EST) Winston's maximum sustained winds dropped to 70 knots (80.5 mph/129.6 kph) making it a Category 1 hurricane.
It was located about 303 nautical miles (348 miles/561.2 km) west-southwest of Suva, Fiji near 20.7 degrees south latitude and 173.8 degrees east longitude. Winston had increased in forward speed since Feb. 22, 2016 and was moving to the south-southeast to 9 knots (10.3 mph/16.6 kph).
JTWC forecasters expect that Winston will turn southwestward to west-southwestward on Feb. 24, 2016 as it transitions to the steering influence of a building sub-tropical ridge (elongated area of high pressure) to the south. Tc 11p is expected to weaken significantly after Feb. 24, 2016 as it encounters strong vertical wind shear and cooler sea surface temperatures.

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
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...
