A team of biologists working in Brazil may have found the clues to resolving the longstanding mystery of why some species of bees, such as honey bees, communicate the location of food with dances in their hives and why other bees simply leave scent trails from the food source to the nest.
In the paper to appear in the October 22nd issue of the Proceedings of the Royal Society, biologists at the University of California, San Diego and the University of São Paulo report that one species of Brazilian stingless bee uses a slightly different form of communication, presumably in an effort to confuse its foraging competitors. An early on-line version of the paper is available at www.pubs.royalsoc.ac.uk/proc_bio/proc_bio.html.
“Previously, biologists thought different species of bees either marked the food source or left an odor trail from the food all the way to the nest,” says James Nieh, an assistant professor of biology at UCSD who headed the study. “We have discovered an intermediate strategy, in which bees leave an odor trail extending a short distance from the food source. This abbreviated trail may be less conspicuous to foraging competitors.”

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...
