The Protein Structure Initiative (PSI), a national program aimed at determining the three-dimensional shapes of a wide range of proteins, has now determined more than 1,000 different structures. These structures will shed light on how proteins function in many life processes and could lead to targets for the development of new medicines.

The PSI is a 10-year, approximately $600 million project funded largely by the National Institute of General Medical Sciences (NIGMS), part of the National Institutes of Health. The first half of this project—a pilot phase that started in 2000—has centered on developing new tools and processes that enable researchers to quickly, cheaply, and reliably determine the shapes of many proteins found in nature.
"One thousand protein structures is a significant milestone for the PSI, and it shows an impressive return on the investment in the technology and methods for rapid structure determination," said Jeremy M. Berg, Ph.D., director of NIGMS. "These structures are interesting in their own right and provide the basis for modeling many important proteins."

The pilot phase of the PSI will end in mid-2005. Centers for the second phase will be announced in July 2005.
In addition to NIGMS, the PSI currently receives funding from the National Institute of Allergy and Infectious Diseases, a component of the National Institutes of Health.

NIGMS is one of the 27 components of NIH, the premier federal agency for biomedical research. The NIGMS mission is to support basic biomedical research that lays the foundation for advances in disease diagnosis, treatment and prevention.

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...
