Surgeons at Western Pennsylvania Hospital report that laparoscopic surgery for obesity, known as Roux-en-Y gastric bypass, effectively improves unhealthy conditions associated with severe clinical obesity (or "morbid" obesity). The results, which were presented at the 69th Annual Scientific Meeting of the American College of Gastroenterology, reveal that after this surgery many patients are able to stop medications for a range of serious obesity-related health problems, including diabetes, sleep apnea, asthma, and high blood pressure.
"Comorbities associated with morbid obesity decrease life expectancy and impair quality of life," notes Pavlos Papasavas, M.D., one of the researchers at Western Pennsylvania Hospital. He and his colleagues followed 455 patients and collected data on medications used to treat comorbid diseases.
At follow-up, almost half (48.7 percent) of patients who took medications for high blood pressure preoperatively were now off medications. In addition, 92 percent of postoperative gastric bypass patients who took both oral medications for diabetes and insulin were off these medications at the time of their last follow-up. Another area of improvement was degenerative joint disease, with 32.5 percent of patients taking medications for this condition preoperatively, of whom 60 percent were off medications at follow-up.

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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
