How do killer T cells know where danger is coming from?
Road signs for immune defence cells - Study generates insights into the inner workings of the adaptive immune response
17-Aug-2022
How do killer T cells recognise cells in the body that have been infected by viruses? Matter foreign to the body is presented on the surface of these cells as antigens that act as a kind of road sign. A network of accessory proteins – the chaperones – ensure that this sign retains its stability ...
Synapses as a model: solid-state memory in neuromorphic circuits
Scientists at Forschungszentrum Jülich publish guide for memristor hardware design
17-Aug-2022
They are many times faster than flash memory and require significantly less energy: memristive memory cells could revolutionize the energy efficiency of neuromorphic computers. In these computers, which are modeled on the way the human brain works, memristive cells function like artificial ...
Protection against COVID-19: experience is not always an advantage for the immune response
A good response to the SARS-CoV-2 vaccination is based on naive immune cells, whereas pre-existing memory cells are rather disadvantageous
16-Aug-2022
People who have often been infected by common cold viruses – which also belong to the coronaviruses – are not better protected against COVID-19, neither after infection with SARS-CoV-2 nor after vaccination. "We already showed in 2020 that earlier exposure to common cold viruses does not provide ...
Mars dust as a basis for life?
No problem for certain bacteria
15-Aug-2022
An international research team led by ZARM scientist Dr. Cyprien Verseux has identified a cyanobacteria subspecies that seems to be best suited for use in a biological life support system that would allow humans to survive on Mars. The results are published in the journal “Applied and ...
Bacterial membrane transporter helps pathogens to hide from immune system
"Our results represent a real breakthrough, since attempts to decipher the structure of a TRAP transporter had already been going on for about 20 years"
11-Aug-2022
The transport of substances across the membrane into the cell is linked to specific membrane transport proteins. Researchers at the University Hospital Bonn (UKB) and the University of Bonn, in collaboration with an international team, have now succeeded in elucidating the molecular structure of ...
Hydrogel keeps vaccines alive
ETH Zurich and Colorado-based start-up to develop one step towards solving a global issue
10-Aug-2022
Most vaccines require constant refrigeration during shipment to remain effective. An international research team led by ETH Zurich has now developed a special hydrogel that vastly improves the shelf life of vaccines, even without refrigeration. The development could save many lives and lower the ...
Comparison of two nano rulers
Study compares two methods for distance measurement in motile proteins
08-Aug-2022
In the Middle Ages, every city had its own system of measurement. Even today, you can sometimes find iron rods in marketplaces that determined the length measurement valid for the city at that time. In science, however, there is no room for such uncertainties, and no matter what method you use to ...
A molecular machine at work
A molecular machine at work
05-Aug-2022
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 ...
Brain tumor cells invade the brain as neuronal free riders
Brain tumor cells imitate characteristics and movement patterns of nerve cells
05-Aug-2022
Certain cells from glioblastomas, the most aggressive form of brain tumors, mimic characteristics and movement strategies of immature neurons to colonize the brain. Fundamental new results from researchers at Heidelberg University Hospital (UKHD) and Heidelberg Medical School (MFHD) and the ...
A Molecule of Light and Matter
Using light, atoms can be made to attract each other
04-Aug-2022
A very special bonding state between atoms has been created in the laboratory for the first time: With a laser beam, atoms can be polarised so that they are positively charged on one side and negatively charged on the other. This makes them attract each other creating a very special bonding ...
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.
