Dieters have higher metabolism, feel less hungry
Preliminary data from Children’s Hospital Boston and Brigham and Women’s Hospital, published in the November 24 JAMA, suggest that weight-loss diets may be more effective when dieters seek to reduce glycemic load – the amount their blood glucose rises after a meal – rather than limit fat intake. The findings indicate that a low-glycemic diet may overcome the body’s natural tendency to slow metabolism and turn on hunger cues to "make up" the missing calories.
The low-glycemic-load (low-GL) diet reduces carbohydrates that are rapidly digested and that raise blood sugar and insulin to high levels -- such as white bread, refined breakfast cereals, and concentrated sugars. Instead, it emphasizes carbohydrates that release sugar more slowly, including whole grains, most fruits, vegetables, nuts, and legumes. "Our data suggest that the type of calories consumed – independent of the amount – can alter metabolic rate," says Dr. David Ludwig, director of the Optimal Weight for Life (OWL) obesity program at Children’s Hospital Boston and the study’s senior investigator. "That hasn’t been shown before. The idea that ’a calorie is a calorie is a calorie’ doesn’t really explain why conventional weight-loss diets usually don’t work for more than a few months."

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...
