In a serendipitous spin-off of HIV/AIDS research, scientists at the National Institute of Allergy and Infectious Diseases (NIAID) and colleagues have found strong evidence that a genetic variation affecting immune system cells protects against heart disease. Details of the work, which also provides further evidence for the role of inflammation in heart disease, will appear in the April 15 issue of the Journal of Clinical Investigation.
"This work demonstrates how NIAIDs commitment to HIV/AIDS research can provide insights into the mechanisms of other diseases," says NIAID director Anthony S. Fauci, M.D. "The money spent on this research, so important to the millions of people around the world infected with HIV, also results in wider ranging benefits."
"The genetic variation we studied has a positive and protective effect against atherosclerosis. This effect is similar in magnitude, though opposite in value, to known negative risk factors such as diabetes and smoking. In other words, as bad as the negative risk factors are bad, this factor is good," says senior study author Philip M. Murphy, M.D. "In addition, the study may help explain part of the hereditary component of heart disease, establishing not only a genetic association but also giving evidence for a biological cause."

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...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
