New data suggests that a novel molecule appears to be involved in the intestine’s response to infection. The study was a collaboration between researchers at Washington University School of Medicine in St. Louis and the Institut Curie in Paris. It appears in the March 13 issue of the journal Nature.
“This is the first identified function for this molecule,” says co-senior author Susan Gilfillan, Ph.D., research instructor in pathology and immunology at the School of Medicine. “Our findings suggest that this molecule may play a fundamental role in gut immunology.”
When a virus enters the body, proteins called antigens appear on the surface of cells and alert the immune system to infection. A molecule called MR1, which was discovered eight years ago, appears to be very similar to the main category of molecules that deliver antigens to the cell surface, called major histocompatibility complex class I (MHC Class I). However, its function is not yet understood.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...

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...
