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.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
