Researchers publish the three-dimensional structure of the B cell antigen receptor, shedding new light on its composition
The surface of B cells is covered with antigen receptors with which they recognize invading pathogens such as bacteria and viruses. When a B cell receptor binds to an antigen, that is, to a foreign structure, the B cell is activated and triggers the production of antibodies. Antibodies are ...
Researchers unravel the assembly of an enzyme that detoxifies the greenhouse gas N₂O
The greenhouse gas nitrous oxide (N2O) is produced as a by-product of industrial processes and through the use of fertilizers in agriculture. It is making a steadily growing contribution to climate change and the depletion of the ozone layer. It is so chemically unreactive that it remains in the ...
Significance for Alzheimer’s, multiple sclerosis and more
What gets into the brain and what doesn’t is strictly regulated. Researchers at the Faculty of Medicine at the University of Freiburg have now studied phagocytes that coat the blood vessels in the brain and reinforce the blood-brain barrier. As the scientists from the Institute of Neuropathology ...
Organoids could be used in diagnosis, drug development, and fundamental research
Laboratory studies of lung tissue usually require the removal of large amounts of human or animal tissue. Now scientists from the University of Freiburg’s Faculty of Medicine have succeeded in collaboration with American researchers in generating tiny quantities of lung tissue, so-called ...
Study shows how the mechanism of photoionization can be used to gain insights into complex molecular potentials
How can researchers use the mechanism of photoionization to gain insight into complex molecular potential? This question has now been answered by a team led by Prof. Dr. Giuseppe Sansone from the Institute of Physics at the University of Freiburg. The researchers from Freiburg, the Max Planck ...
New organ-on-chip system enables precise monitoring of 3D tumour tissue outside the body
A research team around Dr. Andreas Weltin, Dr. Jochen Kieninger and Johannes Dornhof from the Department of Microsystems Engineering (IMTEK) at the University of Freiburg has developed a system that, among other things, makes it possible to study the development of tumour cells outside the human ...
One process has similar CO2 footprint to e-mobility
Technologies for the removal of carbon dioxide (CO2) from the atmosphere (direct air capture, or DAC for short) are already in use, but neither their actual benefits for climate protection nor their other environmental impact have yet to be investigated. A research team led by Kavya Madhu and ...
Researchers find the enzymatic link in the formation of methane from fatty acids by cooperating microorganisms
Microbial production of methane from organic material is an essential process in the global carbon cycle and an important source of renewable energy. This natural process is based on a cooperative interaction between different types of microorganisms: the fermenting bacteria and the ...
Microorganisms can increase their host’s ability to adapt to the environment and reproduce – evolutionary biologists are now studying the underlying molecular mechanisms. A research team headed by Dr. Fabian Staubach and Yun Wang from the Institute of Biology I at the University of Freiburg has ...
Researchers discover enzyme prototype for formation of ecologically and pharmaceutically important tropone compounds
Microorganisms produce natural products, for example, as disease-causing virulence factors or as defense substances against predators and competitors. A team led by Dr. Robin Teufel and first author Ying Duan from the Institute of Biology II at the Faculty of Biology of the University of ...
q&more – the networking platform for quality excellence in lab and process
The q&more concept is to increase the visibility of recent research and innovative solutions, and support the exchange of knowledge. In the broad spectrum of subjects covered, the focus is on achieving maximum quality in highly innovative sectors. As a modern knowledge platform, q&more offers market participants one-of-a-kind networking opportunities. Cutting-edge research is presented by authors of international repute. Attractively presented in a high-quality context, and published in German and English, the original articles introduce new concepts and highlight unconventional solution strategies.
