New and effective treatments for lung cancer may rest on their ability to hinder the action of estrogen in lung cancer cells, according to two studies published in the current issue of Cancer Research. The University of Pittsburgh studies build on current knowledge about the relationship between estrogen and lung cancer growth and suggest that blocking estrogen may be vitally important to improving survival from the disease.
Since 1930, a 600 percent increase in death rates from lung cancer has been reported in women in the United States, leading some experts to suggest that women may be more susceptible to lung cancer than men. The current research contends that this could be due to the effects of estrogen on the lungs.
"Our studies continue to show that lung cancer cells grow in response to estrogen and that stopping or slowing the spread of the disease may be dependent on blocking the action of estrogen," said Jill Siegfried, Ph.D., professor, department of pharmacology and co-leader, Lung and Thoracic Malignancies Program, University of Pittsburgh Cancer Institute. "In fact, in previous studies, we have observed that lung tumor cells contain estrogen receptors at levels comparable to breast cancer cells." A receptor is a structure on the surface of a cell that selectively receives and binds substances.

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
