Researchers at Dana-Farber Cancer Institute and the Whitehead Institute have discovered a pattern of genetic activity in several types of primary tumors that appears to predict the likelihood that they will spread, or metastasize, to other parts of the body. If larger studies support these findings, this early indicator of life-threatening cancer spread might lead to a clinical test that would help determine appropriate treatment.
The study will be published by Nature Genetics on its web site on Dec. 9.
Most cancer deaths are caused not by the original or primary tumor but by the metastasizing of tumor cells to other organs. Until now, cancer specialists have viewed the development of metastasis as an essentially random and unpredictable event.
But that notion is thrown into question with the new finding of a genetic "signature" – a certain pattern of activity in a handful of genes – in some solid tumors that appears to preordain them to spreading dangerously. This signature is present in the early stages of the cancer, well before there is any evidence of metastasis, say the researchers.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

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...
