Severe infections with Group A streptococci, sometimes called “flesh-eating killer bacteria,” are considerably more common than expected in many countries. In an EU project covering 11 countries, headed by Lund University in Sweden, it was calculated that some 1,000 cases would be found over an initial 1½-year period. Fully 5,000 were identified.
Group A streptococci, GAS, can sometimes occur in the throat without the carrier noticing anything. In other cases, the bacteria can cause a benign form of strep throat or skin infection. But in some cases, partly depending on the nature of the bacterial strain, a throat or skin infection can lead to serious consequences, with chronic heart and kidney damage. An acute GAS infection of the skin, for instance, can also dig deeper and lead to the muscles’ being virtually eaten up by the bacteria. In other cases the bacteria can spread rapidly and the body’s fine blood vessels start to leak fluids, which can lead to loss of blood pressure and rapid death, even in a young and previously healthy person.
“Our study has attracted a lot of attention, and we have had to turn down a number of countries that have wanted to be included in the project afterward,” says Aftab Jasir from the Section for Bacteriology at Lund University. She and her colleague Claes Schalén act as coordinators of the EU study.

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...
