The researchers analyzed markers of ovarian reserve in 20 premenopausal breast cancer patients who had been treated with adjuvant chemotherapy, who were one or more years out from their diagnosis, and who had no evidence of recurrence. This group was compared with a "control" group of 20 like-aged women without a history of the disease.
The evaluation involved five tests conducted two, three or four days after a menstrual cycle to assess the ovaries' physical condition, hormone levels and a compound involved in the menstrual cycle. In four of the five tests, the breast cancer survivors had a worse ovarian reserve than did the control group. The other test showed no major difference between the two groups.
"These findings may have important implications for women who are interested in having children after receiving chemotherapy," said Ann Partridge, MD, MPH, of Dana-Farber, who led the study. "Studies that track breast cancer survivors following treatment are needed to determine the predictive value of these tests for pregnancy."

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...
