There is a sound neurological basis for the cliché that men are more aggressive than women, according to new findings by scientists at the University of Pennsylvania School of Medicine.
Using magnetic resonance imaging (MRI) scans, the Penn scientists illustrated for the first time that the relative size of the sections of the brain known to constrain aggression and monitor behavior is larger in women than in men.
The research, by Ruben C. Gur, PhD, and Raquel E. Gur, MD, PhD, and their colleagues in Penns Department of Psychiatry and the Department of Epidemiology, is published in the recent issue of the Journal of the Cerebral Cortex.

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...
