A new study done in the area burned in the catastrophic Biscuit Fire in Southwestern Oregon in 2002 found that allowing trees to naturally regenerate works about as well or better than logging and replanting, and that undisturbed areas may be at lower fire risk in the future.
The research will be published Friday in Sciencexpress and later presented in the journal Science, by scientists from Oregon State University and the Institute of Pacific Islands Forestry in Hawaii. It provides some of the first actual data about forest regeneration in this vast, burned area.
Even following a high severity fire such as this, which covered more than 450,000 acres and was the largest in Oregon history, the natural conifer regeneration on study sites was about 300 seedlings per acre, and 80 percent Douglas fir. However, logging reduced the regeneration by 71 percent, and would necessitate manual planting to restore seedling levels that otherwise would have occurred naturally.

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.

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...
