A University of Alberta scientist is part of a research team offering the first evidence that global warming is behind an infectious disease epidemic wiping out entire frog populations and forcing many species to extinction. The work is published in the journal "Nature."
"When we talk about climate change, there is so much focus on industrialized countries, but people are ignoring other ecosystems that may be extremely sensitive to climate change, such as dry and cloud forest environments," says Dr. Arturo Sanchez-Azofeifa, from the U of As Department of Earth and Atmospheric Sciences and one of the papers co-authors. "Its impact goes beyond what we can observe here in Canada and the north, and the situation is obviously very grave."
Sanchez-Azofeifa is part of an international research team led by Dr. Alan Pounds from Costa Ricas Monteverde Cloud Forest Preserve and Tropical Science Centre. Accounting for such things as deforestation, the scientists investigated how the Monteverde harlequin frog vanished along with the golden toad 17 years ago from the mountains of Costa Rica. About 67 per cent of the 110 species of the particular frog--which only existed in the American tropics--have met the same fate due, say the researchers, to a pathogenic fungus called Batrachochytrium dendrobatidis.

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...
