Data from a five-year study suggests that limited-field radiation therapy (radiation directed at the tumor site) may be as effective as whole-breast radiation therapy in preventing breast cancer recurrence in women treated with breast-conserving surgery. The study appears in the August 20 issue of the Journal of the National Cancer Institute.
Whole-breast radiation therapy is part of standard treatment for women with early-stage breast cancer who have undergone breast-conserving surgery. However, it has never been clear how much tissue surrounding the tumor bed needs to be irradiated, and whole-breast radiation therapy has been associated with both acute and chronic toxicity. Researchers are now looking at whether limited-field radiation therapy could be a better option for patients at low risk for recurrence.
Frank A. Vicini, M.D., of the William Beaumont Hospital in Royal Oak, Mich., and his colleagues compared rates of local recurrence between 199 women treated with limited-field radiation therapy and 199 matched control women treated with whole-breast radiation therapy. All of the women had early-stage breast cancer and were treated with breast-conserving surgery; women were matched by age, tumor size, lymph-node status, margins of excision, estrogen receptor status, and use of adjuvant tamoxifen therapy.

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...

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...
