In the world of molecules, DNA tends to get top billing at the expense of RNA, which is critical for turning DNAs genetic blueprint into working proteins. Researchers at the Stanford University School of Medicine have published significant insights into how the RNA molecule completes this task in two back-to-back papers in the Feb. 13 issue of Science.
All the genetic information contained in DNA is silent, said Roger Kornberg, PhD, the Mrs. George A. Wizner Professor in Medicine and professor of structural biology. What gives it a voice is RNA polymerase, the enzyme that copies DNA into RNA through a process called transcription. Along with more than a dozen helper molecules, RNA polymerase determines which proteins are produced within a cell. But before scientists can understand the transcription process, they must first unveil the inner structure of RNA polymerase.
Kornbergs lab has been studying RNA and the enzyme that makes it for more than 20 years. Past studies from the lab have shown that the machinery of the RNA polymerase system is in three layers. Kornbergs group published groundbreaking findings in 2001 outlining the structure of the innermost layer. The two current papers focus on the middle layer, which contains many of the helper molecules.

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...
