HIV selectively inserts itself into active areas of a host cells genome, Salk Institute researchers have found for the first time. The fact that the virus hooks itself up to areas of the cells genome that are busy expressing themselves may help explain why HIV can replicate, or reproduce itself, so rapidly. The findings are being published as the cover article in the Friday, August 23, issue of the journal Cell.
"HIV seems to be targeting not just genes, but active genes," said Salk researcher Frederic Bushman, a specialist in infectious diseases who headed the research team. "That makes a lot of biological sense if the targeting has evolved to promote efficient expression of the viral genome once it integrates into the cell."
The findings may have implications for developing more effective gene therapies, said Bushman, Associate Professor in the Infectious Disease Laboratory. Gene therapy involves treating genetic disorders by using a mutated retrovirus to insert a new gene into a defective genome. Gene therapy could be made safer and more effective by knowing more about and taking advantage of a retroviruss targeting specificity, he said.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
