Bees and their young are healthier when mites live-in, report researchers from the Smithsonian Tropical Research Institute in Panama and the University of Texas at Austin.
Mutually beneficial cleaning relationships have been documented for shrimps and fish that eat parasites on larger fish, but this is the first confirmation of a cleaning relationship between two different species on land.
Tropical sweat bees in the genus Megalopta tunnel into rotten wood, excavating cells for their young that they feed with nectar and pollen. Researchers working at field sites throughout Panama noticed that sweat-bee nests sometimes housed mites and that more young bees died in nests that did not contain mites than in nests that did.
"The mutualistic nature of bee-mite symbioses was hypothesized repeatedly but had never been demonstrated empirically," said Natalia Biani, short-term fellow in Staff Scientist William Wcislo's lab at STRI and graduate student in professor Ulrich Mueller's lab at the University of Texas, Austin.Biani placed the contents of the brood cells in water and plated the liquid on Petri dishes in order to count the number of fungal colonies from nests with and without mites. "When we took away the mites, the bee nests got dirtier. When we added mites, fungus counts went down. It is pretty clear that the mites clean up the cells where the young are growing," Biani said. In return, the mites receive a clean, dry home, fungus to eat and free bee rides to new nests.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
