A new capsule that contains a microscopic camera and transmitter can create better pictures of the small bowel than standard x-ray procedures can, a new study shows. The capsule is easily swallowed by the patient, and there is no need for the patient to drink barium before the procedure.
The study, conducted by Sandor Joffe, MD, section head of abdominal imaging, and his colleagues at Beth Israel Medical Center in New York, found that wireless capsule endoscopy was better able than a small bowel series to find the cause of the patients symptoms. The small bowel series consists of a series of x-rays of the abdomen after the patient drinks several cups of barium.
Twenty patients underwent both the wireless capsule endoscopy and the small bowel series, says Dr. Joffe. These patients had a variety of symptoms; many of them were being examined because they were anemic or blood had been detected in their stool.

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...
