"Take two cheeseburgers and call me in the morning," may sound like far-fetched medical advice. After all, high fat foods can worsen blockages in blood vessels. But a new study in the October 17 issue of The Journal of Experimental Medicine shows that high fat foods can, at least in the gut, soothe inflammation. This action may stop immune cells from attacking food as a foreign invader.
Eating -- particularly eating fat-rich foods -- causes cells in the small intestine to produce a hormone called cholecystokinin, or CCK. CCK stimulates digestion and gut peristalsis (the motion that propels food along the digestive tract), and also triggers satiation -- the full feeling that prompts you to stop eating.
The study by Luyer and colleagues shows that fat-induced CCK can also dampen inflammation in the gut, as rats fed a high-fat diet were protected against lethal bacteria-induced shock whereas those fed a low-fat diet were not. CCK sent signals to the brain through the vagus nerve, the nerve that provides the electrical regulation for many internal organs, including the gut and the heart. In response to CCK, vagus nerve endings in the gut released a neurotransmitter called acetylcholine. Acetylcholine then bound to proteins on immune cells and turned the cells off.

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
