Dr. Wesley Sundquist, professor of biochemistry at the University of Utah, will present at the Experimental Biology 2003 meeting in San Diego on his work in elucidating how HIV is manufactured and assembled in the cell.
The raison dêtre of a virus such as HIV, if a non-living thing can be said to have one, is to turn a host cell into a factory that churns out virus copies and releases them to infect other cells. Dr. Sundquists research has focused on discovering the mechanisms underlying this manufacturing process.
By identifying and characterizing the structures of specific cellular proteins that are crucial to assembling HIV, Dr. Sundquist is providing potential new targets for future anti-HIV drugs. For example, he and his colleagues were the first to show that a protein called TSG101 is required for HIV release. HIV needs TSG101 in order to escape from its host cell in a process termed budding. Dr. Sundquists team has also determined the structure of the part of TSG101 to which HIV binds. Finding ways to alter this structure or otherwise block its binding to HIV theoretically would prevent budding and slow or halt the infection.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
