University of Toronto researchers have designed a chemical screening tool that will light up when dangerous pathogens and diseases in air, water and bodily fluids are present.
"This detection technique, which uses DNA to seek out target DNA, could one day be used in clinical care situations to quickly detect diseases such as AIDS and hepatitis," says Professor Ulrich Krull, the AstraZeneca Chair in biotechnology and vice-principal (research) at the University of Toronto at Mississauga. "It could also act to constantly monitor the environment and sound an alarm if harmful agents were to appear."
In a study, outlined in the March issue of Bioorganic & Medicinal Chemistry Letters, Krull and graduate student Xiaofeng Wang used a fluorescent dye attached to probe DNA that binds to specific target DNA sequences, illuminates in the presence of a targeted pathogen or genetic mutation and then sends a detection signal through an optical fibre. By simply adding heat, the dye unbinds and the detection chemistry is ready to test the next sample. The chemical screening system fits onto a microchip and soon could test blood and water samples in a matter of seconds.

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...
