A womans risk of ovarian cancer rises significantly if she carries either of two previously unexamined variations in the gene that codes for the progesterone receptor, according to a team of researchers led by scientists from the Keck School of Medicine of the University of Southern California.
The study, which is being published in the January 5th issue of the Journal of the National Cancer Institute, was initially supposed to be a more in-depth look at one particular version-or allele-of the progesterone receptor gene (PGR). The PROGINS allele, says Celeste Leigh Pearce, a preventive medicine researcher from the USC/Norris Comprehensive Cancer Center and the papers first author, had previously been linked to a higher ovarian cancer risk as well as a lower breast cancer risk in women who carry it.
To see if the PROGINS allele did indeed confer a higher ovarian cancer risk on women, the researchers-led by the studys principal investigator, USC preventive medicine professor Malcolm Pike-first used biological samples collected by the Hawaii/Los Angeles Multiethnic Cohort Study. (The Multiethnic Cohort is one of the largest ongoing population studies in the world, and is led by Brian E. Henderson, M.D., the Kenneth T. Norris Jr. Chair in Cancer Prevention and dean of the Keck School of Medicine.) The scientists examined the variety of genetic variations found in the PGR gene as part of a long-term collaboration between USC researchers and those at the Broad Institute in Cambridge, MA, looking to ascertain if the PROGINS allele held a particular risk of ovarian cancer for women.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
