A report obtained by The Lancet Oncology details a precipitous decline in US Veteran Affairs (VA) reporting of new cancer cases to California registries beginning in late 2004—from 3000 cases in 2003 to almost none by the end of 2005. Inconsistent and incomplete case reporting by VA Hospitals are also long-standing problems for other US states and could mean that cancer rates appear artificially low across the USA.
The omission of veteran data would introduce “uncorrectable bias” in epidemiological studies, and research from the mid-2000s will not be correct, according to Dennis Deapen of the Los Angeles Cancer Surveillance Program. Furthermore, it will hamper efforts to identify quality-of-care issues for VA patients with cancer.
A draft version of the VA policy directive on cancer reporting was obtained by The Lancet Oncology which revealed that the directive will formalise the prohibitions on sharing veteran cancer data between states and forbid the “re-lease” of veteran data to researchers whose studies have not been approved by the VA. “This could become a serious issue for the validity of epidemiological studies” according to Elizabeth Ward of the American Cancer Society. The VA has since posted the final directive on its website.

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.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
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...
