The University of Rochester Medical Center has a new tool to assess whether a medication might be harmful to the heart. The technology addresses a major health issue – drug toxicity – illustrated most recently by Merck’s voluntary withdrawal of Vioxx from the market after concerns that it may cause heart attacks and strokes.
Jean-Philippe Couderc, a biomedical engineer, developed a software program that provides a simpler, more accurate way to analyze the electrocardiograms (EKGs) of people who volunteer for clinical trials to test new drugs. The Food and Drug Administration purchased a copy of the technology, called COMPAS, which stands for Comprehensive Analysis of Repolarization Signal. The university hopes to license the copyrighted software to drug companies and other institutions involved in pre-market drug testing, said John Fahner-Vihtelic, deputy director of the Office of Technology Transfer.
"Our program provides a more reliable method to identify cardiovascular toxicity at a time when the scientific community is diligently seeking ways to address this problem," said Couderc, Ph.D., M.B.A., a research assistant professor in the Cardiology department and assistant director of the Heart Research Follow-up Program. "We are confident that COMPAS will be a valuable tool in the clinical trial and drug development arena."

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...
