Sometimes familiarity does not breed contempt: A Cornell University behavioral scientist has found that female wolf spiders prefer mates that are comfortably familiar.

However, the researcher has discovered, a male wolf spider unlucky enough to attempt to mate with an unfamiliar female probably is doomed to be killed and eaten by the female.
"Finding this behavior is really surprising. Social experience influences mate choice," says Eileen Hebets, a Cornell postdoctoral researcher in the Department of Neurobiology and Behavior, whose findings will be published in the online edition of Proceedings of the National Academy of Sciences (PNAS early edition, Oct. 27-31, 2003).

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...
