An enzyme whose activity is affected by alcohol may prove useful in identifying recent alcohol or marijuna use even though it does not seem to be a good marker for genetic predisposition to alcoholism, a new international study finds. The researchers also found that the activity level of the enzyme, adenylyl cyclase, steadily dropped in people who had abstained from drinking for days to weeks and was generally lower in people with a history of major depression, according to the study published in the July issue of Alcoholism: Clinical and Experimental Research.
Previous research has shown an association between a family history of alcoholism and lower activity levels of adenylyl cyclase, says lead author Paula L. Hoffman, Ph.D., of the University of Colorado Health Sciences Center.
This study, which had a much larger sample size than previous research, shows that the effect of genetic susceptibility to alcoholism on this enzyme’s activity levels is lost in the wake of the more substantial influence of recent alcohol use.

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...
