Infrared data on Tropical Storm Emang's cloud top temperatures was captured by the Atmospheric Infrared Sounder (AIRS) instrument on Jan. 15 at 0823 UTC (3:23 a.m. EST). AIRS data showed that the largest area of powerful thunderstorms were in the northern half of the storm. That area showed cold cloud top temperatures of -63F (-52C) indicating high, powerful thunderstorms where the heaviest rain was falling.

The AIRS data also showed that sinking air or subsidence was occurring in the southwestern quadrant of the storm, which is weakening the convection there.
AIRS data also showed that the low level center of circulation had become slightly elongated, stretching from southwest to northeast. For a tropical cyclone to intensify, its circulation centers from the surface to upper atmosphere basically have to stack up. When the center becomes elongated the storm usually has a difficult time intensifying.
On Jan. 15 at 0900 UTC, Tropical Storm Emang's maximum sustained winds were near 35 knots (40.2 mph/64.8 kph). Emang is moving slowly to the south-southwest at 4 knots (4.6 mph/7.4 kph). Emang was centered near 13.5 south latitude and 78.6 east longitude, about 525 nautical miles (604.2 miles/ 972.3 km) southeast of Diego Garcia. Diego Garcia is a coral atoll in the central southern Indian Ocean.
Forecasters at the Joint Typhoon Warning Center expect atmospheric conditions to improve over the coming days, so that Emang can organize and strengthen. Fortunately, the storm is no threat to land.Text Credit: Rob Gutro

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...
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”.
