New technology has allowed researchers from the University of Chicago to measure, for the first time, how closely well-trained hospital staff comply with established guidelines for cardio-pulmonary resuscitation (CPR). The results reveal room for improvement.
In the 19 January 2005 issue of JAMA, the researchers show that, even in the hospital setting, chest compressions during CPR are often too slow, too shallow and too frequently interrupted, and ventilation rates are usually too high. A second study assessing out-of-hospital CPR by paramedics and nurse anesthetists in three European cities found even greater deviation from the guidelines, suggesting that the problem is endemic.
"CPR has been around for 50 years but until now we havent had a precise, reliable way to assess how well its being done," said study author Lance Becker, M.D., professor of emergency medicine and director of the Emergency Resuscitation Research Center at the University of Chicago. "Now we find that its not being done very well."

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...
