A natural method of disarming some types of viruses may enable scientists to someday treat infections with HIV, the AIDS virus, according to a virologist at Jefferson Medical College.
Taking the lead from the common fruit fly, yeast and worms, scientists have recently shown that it may be possible to use small pieces of genetic material called short interfering RNAs (siRNAs) to inhibit HIV from making more copies of itself.
The process, called RNA interference (RNAi), was first discovered in 1998. It is so novel, says virologist Roger J. Pomerantz, M.D., professor of medicine, biochemistry and molecular pharmacology and chief of the division of infectious diseases at Jefferson Medical College of Thomas Jefferson University in Philadelphia, that scientists only now are beginning to understand its potential to treat disease. "Whats so exciting for HIV therapy is that it may be a potent way of specifically inhibiting the virus," says Dr. Pomerantz, whose commentary accompanies a paper on the topic in the July 2002 issue of Nature Medicine.

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...
