In the March issue of Frontiers in Ecology and the Environment, Max Moritz (University of California, Berkeley), Jon Keeley (US Geological Survey and University of California, Los Angeles), Edward Johnson (University of Calgary) and Andrew Schaffner (Cal Poly State University, San Luis Obispo) present research that challenges some of the assumptions for managing fire-prone regions. With "Testing a basic assumption of shrubland fire management: how important is fuel age?," the authors suggest natural fire regimes, such as those found in southern California, are "more driven by extreme weather conditions" than age-related traits of the regions plant life.
Examining the fire history of coastal and southern California shrublands, the group discovered that the majority of shrublands risk of burning was fairly steady, at about 2.7 percent each year.
"Historical fire patterns and quantitative measures of hazard therefore refute the common assumption that fire probabilities in shrublands are strongly driven by vegetation age, and that large fires are necessarily caused by a buildup of older fuels," according to the study.

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...
