Physicists at Umeå University, in collaboration with researchers in China, have developed a laser made entirely from biomaterials—birch leaves and peanut kernels. The environmentally friendly laser ...

The pinkish-red spots on your birch’s leaves appear to be erineum patches, which are a type of gall caused by very tiny eriophyid mites feeding on the leaf tissue. You will need a microscope to see ...

At first I thought those hundreds of rolled-up leaves on the two old birches holding the hammock were catkins, those long, thin flowers we see in the spring. Of course, that was easy to think with a ...

A renewable, low impact random laser built from birch leaves and peanuts shows a path to affordable medical diagnostics using fully sustainable materials. (Nanowerk News) Physicists at Umeå University ...

Today, petrochemical compounds and rare metals such as platinum and iridium are used to produce semiconductors for optoelectronics, such as organic LEDs for super-thin TV and mobile phone screens.

An international team of researchers led by physicists at Sweden’s Umeå University discovered that by pressure-cooking birch leaves, it is possible to produce a nanosized carbon particle with ...

Brown birch trees in both Southcentral and Interior Alaska this summer aren’t signaling an early fall. Rather, they are subject to an infestation of small, leaf-munching larvae. Alaska is in the midst ...

Many birch leaves in Fairbanks and Anchorage are going from green to brown as the result of an insect infestation. U.S. Forest Service entomologist Stephen Burr in Fairbanks says a leaf mining bug ...

The new pressure-cooking method, developed by physicists at Umeå University, Sweden, in collaboration with researchers in Denmark and China, can break down plant biomass starting material into ...
