A team of researchers has discovered a genetic variation that doubles the risk for rheumatoid arthritis (RA). The variation, referred to as a single nucleotide polymorphism (SNP, pronounced "snip"), is present in about 28 percent of individuals with rheumatoid arthritis and 17 percent of the general population. This discovery resulted from a collaboration between scientists from the North American Rheumatoid Arthritis Consortium (NARAC), led by Peter K. Gregersen, MD, of the North Shore-Long Island Jewish Research Institute in Manhasset, NY, Celera Diagnostics and Genomics Collaborative, Inc. The teams findings are being published in the August 2004 issue of the American Journal of Human Genetics.
"This is an important discovery, really a major genetic variant identified in a U.S. study that clearly seems to be involved in rheumatoid arthritis," said Stephen I. Katz, MD, PhD, director of the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), the lead agency at the National Institutes of Health (NIH) that supports NARAC.
While scientists still do not know the exact cause of RA, they do know it is an autoimmune disease in which the bodys natural immune system does not function properly and attacks its own healthy joint tissues. This causes inflammation and subsequent joint damage.

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...
