Pieris butterflies are not like all other butterflies. Both sexes agree about sex. In a dissertation about olfactory communication, Johan Andersson, a scientist at the Royal Institute of Technology in Stockholm (KTH), Sweden, presents exciting new findings about a joint effort that provides an alternative view of the theory of sexual selection.
The Western man gives his partner an engagement ring when he wants to show the world that this woman is spoken for. When mating, the male white-winged rape-seed butterfly instead gives his partner methyl salicylate-a turn-you-off odor that serves the same purpose. The next male butterfly needs only a second to realize that the race is run and flies on to the next female.
The idea of a so-called anti-aphrodisiac has been known for some time, but it is only now that it is possible to show how the system works in its entirety, exactly what substances are involved and above all that the whole thing is a collaborative effort between male and female and not a conflict.

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...
