Patients who have had colorectal cancer may reduce their risk of suffering a recurrence by taking an aspirin daily, according to a new study conducted by a University of North Carolina at Chapel Hill physician and colleagues around the United States.
The study showed that subjects who took 325 milligrams of aspirin each day had a 35 percent lower risk of developing polyps in their colons during the period examined than did patients who received an inactive placebo. Polyps are considered precursors to most colorectal cancers. A report on the findings appears in the March 6 issue of the New England Journal of Medicine. More than 100 medical centers and clinics throughout the United States participated in the study.
"From both animal research and observational studies, weve recognized for a long time that aspirin might decrease the risk of colon cancer," said Dr. Robert S. Sandler, the studys principal investigator. "To find out whether aspirin really worked, we needed a randomized trial where we could compare aspirin with a placebo. With the help of a large consortium of hospitals and a large number of patients, thats what weve done. "

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.

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...
