A team including scientists at UCMP (Umeå Center for Molecular Pathogenesis), a research unit at Umeå University, shows in last week’s issue of the journal Science that the protein PGRP-LC plays a crucial role in so-called innate immunity.
Professor Dan Hultmark, post-doctoral fellow Svenja Stöven, and doctoral candidate Thomas Werner at UCMP are focusing their attention on the mechanisms behind natural, or innate, immunity, and they are using the fruit-fly, Drosophila melanogaster, as a model system. The aim is, one the one hand, the better to understand the corresponding system in humans and, on the other hand, the fact that immunity in insects is itself important, mainly because a large number of diseases are spread by insect vectors.
When insects are infected by bacteria or fungi they react by producing effective antidotes in the form of special proteins and peptides that kill the invaders. This natural immune defense is triggered by substances from the invaders’ cell walls.

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...
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...
