A discovery by a University of California, San Diego biologist that some species of bees exploit chemical clues left by other bee species to guide their kin to food provides evidence that eavesdropping may be an evolutionary driving force behind some bees’ ability to conceal communication inside the hive, using a form of animal language to encode food location.
Bees can use two main forms of communication to tell their hive mates where to find food: abstract representations such as sounds or dances within the hive or scent markings outside the hive to mark the food and/or the route to it. In 1999, James Nieh, an assistant professor of biology at UCSD, published a paper in which he hypothesized communication within the hive may have evolved as a way of avoiding espionage by competitors.
Nieh’s most recent study, a collaboration with Brazilian biologists published June 16 in the early on-line version of the journal Proceedings of the Royal Society, is strong support for that hypothesis because it shows that bees can indeed use the chemical markings deposited by bees of other species to home in on and take over their food source. The paper will appear in print in Proceedings of the Royal Society in August.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
