Gene that lets you eat as much as you want holds promise against obesity

It sounds too good to be true, but a novel approach that might allow you to eat as much as you want without gaining weight could be a reality in the near future. When a single gene known as RCAN1 was removed in mice and they were fed a high fat diet, they failed to gain weight, even after gorging on high fat foods for prolonged periods.

Crystal clear: Understanding magnetism changes caused by crystal lattice expansion

An international team has demonstrated helimagnetic behavior in a cubic perovskite material by expanding the lattice through barium doping. The experimental findings were well supported by calculations from first principles, showing that the materials were highly sensitive to the lattice constant. It is hoped that the findings will form the foundation for new applications in sensing.
