USDA Forest Service researchers at the Southern Institute of Forest Genetics (SIFG) in Saucier, MS are mapping genes in the pathogen that causes fusiform rust to provide future forest managers with more insurance against the damaging disease.
Fusiform rust, a fungus that forms spindle-shaped galls on the branches and stems of pine trees, is endemic to the southern U.S., occurring from Maryland to Florida and west to Texas and southern Arkansas. Attacking several southern pine species, the fungus is most damaging to loblolly and slash pines. Both the frequency and severity of the disease have increased dramatically over the last 50 years.
"In old-growth natural forests, pine and fusiform rust co-evolved without severely limiting one another," said Tom Kubisiak, research geneticist at SIFG, a unit of the FS Southern Research Station. "In modern intensely managed plantations, planting limited numbers of the most highly productive families has actually contributed to an epidemic of fusiform rust."

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
