Genetically engineered mice, created at the University of Michigan Medical School, are living every dieter’s dream. They eat unlimited amounts of high-fat mouse chow, but have about 50 percent less body fat than normal mice on a low-fat diet. And they show no signs of diabetes or other metabolic disorders, which are common in animals with too little fat.
But don’t stock up on potato chips and ice cream just yet. The genetically altered mice are leaner than normal mice, but they also have some less-than-desirable characteristics – such as underdeveloped mammary glands, an inability to generate body heat and skin that’s twice as thick as normal.
All these changes appear to be caused by a protein called Wnt10b, which is present in artificially high amounts in fat tissue from the experimental mice. Wnt10b is one of a family of 19 related proteins. Wnts (pronounced “wints”) regulate the complex changes that take place as an embryo grows. Part of this process is the development of fatty adipose tissue, which contains fat cells called adipocytes.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
