Later in the day at 1700 UTC (1 p.m. EDT) on July 8, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua satellite captured a visible image of Tropical Storm Chantal. The image showed the Chantal continued to organize as it moves through the Caribbean Sea. Tropical storm force winds extend outward up to 90 miles (150 km) mainly to the north of the center, but the extent of the cloud cover appears larger in visible imagery.
NASA's TRMM satellite showed that the most intense rain falling in Tropical Storm Chantal on July 8 was falling at a rate of over 115.5 mm/hr. (~4.5 inches) near Chantal's center of circulation.

As of 8 a.m. EDT on July 9, a tropical storm warning was in effect for: Barbados, Dominica, St Lucia, Martinique, Guadeloupe, Puerto Rico and southern coast of the Dominican Republic from Cabo Engano to the border with Haiti. In addition, a tropical storm watch was in effect for the U.S. Virgin Islands, Saint Vincent, Vieques and Culebra, Haiti, the northern coast of the Dominican Republic, Turks and Caicos and the southeastern Bahamas.
The National Hurricane Center (NHC) noted that a storm surge of 1 to 3 feet above normal tidal levels can be expected in the Windward and Leeward Islands and Puerto Rico. Along the southern coast of the Dominican Republic, the surge is expected to be higher, reaching 2 to 4 feet. The heavy rainfall that NASA's TRMM satellite observed can be expected over the Leeward and Windward Islands, with totals between 2 to 4 inches, and isolated totals to 6 inches.
NHC expects tropical storm conditions are expected to affect portions of Windward Islands today, July 9, and Puerto Rico tonight or early Wednesday.
At 8 a.m. EDT Chantal's maximum sustained winds were near 50 mph (85 kph). NHC expects some strengthening. Chantal was centered near 13.8 north latitude and 59.7 west longitude, just 45 miles (70 km) north-northwest of Barbados, and 85 miles east of St. Lucia. Chantal was moving to the west-northwest at a speedy 26 mph (43 kph), and is expected to continue in that general direction for the next couple of days. Minimum central pressure is near 1010 millibars.
Chantal's center is expected to move into the eastern Caribbean Sea during the afternoon and evening of July 9 and near the Dominican Republic by July 10. Current forecast tracks from the NHC bring Chantal along the eastern coast of Florida by the weekend of July 13 and 14.

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”.
