A study of a recently discovered microRNA gene reveals that its function is to regulate the secretion of insulin in the pancreas. The findings, which for the first time define a biological function for a mammalian microRNA gene, are published in the November 11 issue of Nature.
The discovery was made by a team of researchers from Rockefeller University, Lund University (Sweden), New York University, and Oxford University.
MicroRNA genes are a newly discovered large class of regulatory genes that do not encode proteins. Although these genes are present in virtually all multi-cellular organisms, their biological function had been largely unclear. In the study, microRNA miR-375 was found to regulate insulin secretion. NYUs Nikolaus Rajewsky, a new genomics faculty member in NYUs Center for Comparative Functional Genomics and an assistant professor in the Department of Biology, developed a computer algorithm to predict the targets of microRNAs in the genome. In the study, predicted gene targets for miR-375 were verified experimentally, thereby making an important contribution for understanding miR-375 function in regulating insulin secretion.

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...
