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.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
