In the first study of native African honeybees and honey-making stingless bees in the same habitat, humans and chimpanzees are the primary bee nest predators. Robert Kajobe of the Dutch Tropical Bee Research Unit and David Roubik from the Smithsonian Tropical Research Institute report this finding in the March, 2006 issue of Biotropica.
Batwa Pygmies, who have traditionally harvested honey for food, located 228 bee nests (both honeybees and stingless bees) for the study. Roubik identified the bees and found that Pygmy names for the bees corresponded to scientific names, except for a black and a brown form of Meliponula ferruginea. Honeybee (Apis) nests were numerous compared to other sites in the tropics, whereas honey-making stingless bee nests were relatively scarce. Nest abundance did not vary with altitude, nor did pollen collection or the seasonality of flowering.
Both honey bees and stingless bees make honey. Apis mellifera, the most commonly cultivated honeybee, is native to Europe and Africa. Apis mellifera subspecies scutellata, the very defensive tropical African honeybee, was transplanted from Africa to Brazil as part of a scientific experiment to boost honey production in 1956. From Brazil, it invaded the Americas, working its way northward and is now found in southern U.S. states.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
