Burr chervil is a new weed exploding across northern Idaho’s landscape. The weed may offer important clues to the biology of invasive species in general, a University of Idaho scientist says.
A decade ago, burr chervil seemed like it didn’t pose much of a threat, said Tim Prather, a UI weed scientist at Moscow. “We knew of a few plants that grew under hawthorn trees near Lewiston. It just seemed to be sitting there and not doing much.”
That was when Prather was doing graduate work at UI in the early 1990s. After completing his education and starting his career, he returned to UI as an weed science professor in 2000. Burr chervil had changed.“We would find it in places we never expected it while we were looking for other weeds,” Prather said.

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
The vacuum is not empty. It may sound like magic to laypeople but it has occupied physicists since the birth of quantum mechanics.
