The cause of the attack was ascertained through blood tests of the victims, but that was only possible once they were already infected. Today we are all more aware of the dangers of biological weapons, but if we were to be subject to such an attack how would we quickly know whether it was a hoax or a biological threat. To tackle this problem scientists at the University of Surrey in a study sponsored by Smiths Detection have found a technique that may allow the authorities to identify biological agents more quickly and efficiently.
The problem in detecting harmful bacteria in the air is that it is mixed up with other non-biological pollutants such as diesel fumes. Until now it has been impossible to separate these non-biological particles from the bacteria which need to be tested, thus quick, accurate identification of bacteria is difficult. Dr Fatima Labeed and her team at the University of Surrey have used a unique form of the process called dielectrophoretic separation to correctly separate diesel particulates from those of an anthrax bacteria substitute. This process would enable the authorities to isolate the bacteria more quickly and therefore use the appropriate biosensing instruments to work out what form of bacteria had been released.
Whilst the process at this point has only been used to separate diesel particle from anthrax-like microorganisms, it is hoped that applications for other potentially dangerous biological materials may also be found. Dr Labeed comments. “Perhaps one day this technology could be as common as x-ray machines used in airports”

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

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.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
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...
