In a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden, researchers have discovered properties of insulin which reduce inflammation caused by obesity and can therefore lower the risk of type 2 diabetes.
Research has shown that both obesity and insulin resistance are affected by inflammatory conditions in the body. Previously it was believed that fat tissue served merely as a depository for fat, but now scientists know that it is also an important organ for the release of a wide range of different substances, including inflammatory molecules. In the thesis, the researchers managed to identify the properties of the inflammatory molecule IL-6.
“IL-6 impairs insulin signalling, but the insulin signalling itself can also inhibit and ‘turn off’ the IL-6 signal and inflammation,” says Wallerstedt. “The protein PKCdelta also plays an important role in the regulation of the IL-6 signal, and we have shown that if we disable the function of this molecule, the inflammation decreases.”
A greater understanding of these signalling mechanisms could make it possible in the future to develop medicines that can “turn off” the inflammation and so reduce the risk of insulin resistance and other obesity-related disorders.DIABETES

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
