In what may be a first step toward expanding the arsenal against HIV, UC Irvine researchers have successfully targeted an HIV protein that has eluded existing therapies.
Researchers targeted Nef, a protein responsible for accelerating the development of acquired immunodeficiency syndrome, or AIDS. Nef was targeted with small molecules synthesized by the researchers – molecules that disrupted Nef’s interaction with other proteins. The technique used for identifying the synthetic molecules also may lead to new drug therapies with improved treatment options.
The researchers used a scientific technique called “phage display,” which is used to identify small molecule inhibitors that can disrupt interactions between proteins. According to Gregory Weiss, lead researcher and assistant professor in the Department of Chemistry, his research team attached the Nef protein to the surface of a harmless virus, then created synthetic molecules that could target and dislodge the protein. This is the first time phage display has been used to identify molecules that disrupt protein-protein interactions. (For more detail, see “About the Research.”)

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

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...
