Researchers are using a herpes virus that produces a firefly enzyme to illuminate the viruss course of infection in mice and to help monitor the infections response to therapy. The work is published by scientists at Washington University School of Medicine in St. Louis in the December issue of the Journal of Virology.
"This study demonstrates the feasibility of monitoring microbial infections in living animals in real time," says study leader David A. Leib, Ph.D., associate professor of ophthalmology and visual sciences and of molecular microbiology. "The technique enables us to follow an infection over time as it progresses and resolves, and we can do this repeatedly using the same animal."
This technology may solve several problems in studying herpes infections and the genes that control them. To investigate the progress of an infection over a course of days, for example, researchers normally must sacrifice infected mice each day and analyze their tissues to determine the level of virus present. The process is further complicated by the fact that individual mice respond differently to infection.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
