Laboratories at The Scripps Research Institute (TSRI) are investigating antibodies to fight Ebola virus, including the three antibodies recently used to treat two American health care workers infected with the Ebola virus.
The conditions of two Americans have reportedly improved since they received a highly experimental antibody cocktail called ZMapp, supplied by San Diego-based Mapp Biopharmaceutical.

The TSRI laboratories of Professor Erica Ollmann Saphire and Assistant Professor Andrew Ward are studying the structures of these antibodies using techniques called electron microscopy, which creates high-resolution images by hitting samples with electrons, and X-ray crystallography, which determines the atomic structure of crystalline arrays of proteins.
Through these images, the team will discover exactly how the immune system molecules bind to the Ebola virus and stop it from functioning, a critical step in drug development.
Ebola virus causes an extremely virulent disease that currently leads to death in 25 to 90 percent of cases. The fast-moving virus is spread via the blood or other bodily fluids of an infected person,
“What we’re showing are sites of vulnerability on the surface of the virus,” said C. Daniel Murin, a graduate student in the Saphire and Ward labs. “These are the chinks in the armor of the virus and the places were you would want your anti-serum to target.”
The ZMapp treatment is still in experimental stages and has not yet been approved for use outside the two recent cases. According to Saphire, ZMapp is one of the best antibody cocktails currently known, but there may still be ways to improve it. She is currently leading a $28 million National Institutes of Health-funded consortium to test antibody cocktails from laboratories around the world, with the goal of finding the best for neutralizing Ebola virus and the many other viruses like it.
An ideal antibody cocktail would ease symptoms and improve the prognosis of infected individuals—it could even work as a preventative measure, protecting healthcare workers before they enter an infected area.
The work on the Ebola virus is part of a larger Vaccine and Global Health Initiative at TSRI, which includes research on HIV/AIDS, influenza and tuberculosis.

About the Scripps Research Institute
The Scripps Research Institute (TSRI) is one of the world's largest independent, not-for-profit organizations focusing on research in the biomedical sciences. TSRI is internationally recognized for its contributions to science and health, including its role in laying the foundation for new treatments for cancer, rheumatoid arthritis, hemophilia, and other diseases. An institution that evolved from the Scripps Metabolic Clinic founded by philanthropist Ellen Browning Scripps in 1924, the institute now employs about 3,000 people on its campuses in La Jolla, CA, and Jupiter, FL, where its renowned scientists—including three Nobel laureates—work toward their next discoveries. The institute's graduate program, which awards PhD degrees in biology and chemistry, ranks among the top ten of its kind in the nation. For more information, see www.scripps.edu.

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...
