Researchers at Yale School of Medicine and seven other national institutions are recruiting patients to participate in the Kronos Early Estrogen Prevention Study (KEEPS) to look at the effects of estrogen on heart disease prevention.
The study will explore whether beginning hormone therapy in women during the menopausal transition (ages 42 to 58) protects against atherosclerosis, the major cause of heart attacks. Results from a prior study of older women called the Women’s Health Initiative (WHI) estrogen plus progestin trial suggested there were few benefits of estrogen on atherosclerosis. The National Institutes of Health halted the study in 2002, but KEEPS will explore issues raised by WHI. Women in WHI were postmenopausal, with a mean age of 62.7, yet most women begin hormone treatment much younger, at the onset of menopausal symptoms.
"Once atherosclerosis is present, it is already too late to prevent it," said Yale principal investigator Hugh Taylor, M.D., associate professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale. "We think estrogen can help to prevent the disease if started early enough."

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
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:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
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...
