We offer two well-characterized polygenic mouse models that allow the test of drugs for weight loss and the targeted search for genetic factors influenc-ing fat deposition: The Berlin Fat Mouse (BFM) outbred population and the Berlin Fat Mouse Inbred 860 (BFMI860) strain. BFM has been selected for low protein content and for high fatness and low body mass from a base population of animals bought in several Berlin pet shops. BFMI860 is an inbred derivate of BFM that has been generated by repeated mating of most obese BFM full-sibs after 58 generations of selection. BFM and BFMI860 develop extreme body weight with high body fat mass, but only marginal increased body lean mass. The phenotype is visible already at a very early age. Highest weight gain occurs between 6 and 10 weeks. At standard diet, the adult animals of the BFMI860 strain had a body fat percentage of 22 to 30% in males and 28 to 37% in females compared to 6% in wildtype mice. The animals respond to high fat diet with further increase of adiposity. BFMI860 mice show several features of the metabolic syndrome. <br><br> Consistent with the high genetic variability, BFM animals have a higher varia-bility in the fat percentage and related phenotypes than BFMI860. </p> <p><strong>Benefits</strong><br>

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,...
Broadband rotational spectroscopy unravels structural reshaping of isolated molecules in the gas phase to accommodate water

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...
