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.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
