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."

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
