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.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
