The Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite captured a visible image on Jan. 26 at 03:23 UTC of Tropical Depression Anthony in the South Pacific Ocean. The image revealed a cloud-filled center of the storm.

At 0600 UTC (1 a.m. EST) on January 26, Anthony had progressed west and was now about 455 nautical miles west-northwest of Nomeau, New Caledonia. That places Anthony's center near 19.2 South and 159.1 East. Maximum sustained surface winds are estimated at 25 to 30 knots (28 mph/46 km/hr to 34 mph/55 km/hr) meaning that Anthony is still at tropical depression status.
The infrared imagery from the AIRS instrument showed a well-defined low level circulation center, although dry air is now wrapping into Anthony's northern quadrant. Dry air saps the moisture that creates the thunderstorms that power a tropical cyclone. Generally, the storm's convection (rapidly rising air that creates those thunderstorms) is weak throughout the storm, and only isolated strong areas of convection appear in the southeastern quadrant. That may change in the next day or two, however, as Anthony moves into an area more conducive to maintaining a tropical cyclone.
Vertical wind shear (winds that can weaken a tropical cyclone) has lessened and sea surface temperatures are warm enough to sustain and strengthen a tropical cyclone (between 28 and 30 Celsius/82 and 86 Fahrenheit). Computer forecast models have shown forecasters at the Joint Typhoon Warning Center that as the system tracks westward toward Australia, there is a fair chance that Anthony will regenerate or re-strengthen in the next 24-36 hours. Forecasters in Queensland, Australia will be watching Anthony very closely.

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...

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...
