Satellites provide a bird's eye view of a hurricane's eye, and NASA noticed Hurricane Dora's eye from several of them. Infrared imagery from NASA's Aqua satellite provided forecasters with a clear view of a cloud-free eye in hurricane Dora as she strengthens near Category 5 status today. Meanwhile the GOES-11 satellite captured a movie of Dora's intensification over the last two days that clearly shows a developing eye.

GOES satellites are operated by NOAA, and the NASA GOES Project located at NASA Goddard creates images and compiled them into the video of the storm. The animation includes sped up infrared and visible frames of data that were captured every 15 minutes from the GOES-11 satellite and squeezed down to 26 seconds.
At 11 a.m. EDT on July 21, 2011 Dora's maximum sustained winds were near 155 mph (250 kmh), right on the brink of Category 5 hurricane status. Fortunately, Dora's center is remaining at sea, and will continue to remain at sea as it moves to the northwest near 12 mph (19 kmh). It is expected to continue in that direction for the next couple of days and slow down.
Dora was centered near 17.1N and 106.9W, about 240 miles (390 km) south-southwest of Cabo Corrientes, Mexico. Minimum central pressure is 929 millibars.
Dora is far enough off the coast so that there are no watches and warnings over land. However, Dora is sending large ocean swells against the beaches of western Mexico today. Those large, rough, ocean swells will affect the coast over the next couple of days, and will also begin affecting the southern Baja California coast.
The National Hurricane Center expects some weakening by tonight and a rapid weakening on Friday as Dora starts battling wind shear and moves into cooler waters.

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...
