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.”

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
