Researchers now have a much better picture of how follicle-stimulating hormone (FSH), one of the most frequently used fertility drugs, works, and with it new ideas for creating a new generation of oral medications to treat infertility.
The exquisite detail of the images produced by Howard Hughes Medical Institute (HHMI) investigator Wayne A. Hendrickson and colleague Qing Fan begins to tell for the first time how the FSH hormone attaches to a key segment of its receptor on the cell surface. The binding of the hormone to its receptor then stimulates the maturation of ovarian follicles in women or sperm production in men.
Insights gleaned from this structure could aid in the development of improved fertility drugs or contraceptives for both men and women. Hendrickson and Fan, who are both at Columbia University, reported the details of the structure in an article published in the January 20, 2005, issue of the journal Nature. "Although the nature of FSH and other glycoprotein hormones has been known for more than 30 years, there is still no orally active therapeutic drug," wrote James A. Dias of the Wadsworth Center in a commentary in the journal Nature. "But such a drug might one day be developed, thanks to the findings presented by Fan and Hendrickson."

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:...

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...
