How pollen increases susceptibility to virus infection
Researchers describe how birch pollen affects immune cells
06-Sep-2022
Birch pollen is not only a nuisance for allergy sufferers. They can also affect the cells of the innate immune system and make them more susceptible to viral infections. This was now shown by a team of researchers at TWINCORE in Hanover, together with cooperation partners from the University of ...
A greener route to blue
A new method drastically reduces the amount of solvent needed to produce widely used organic dyes
02-Sep-2022
Organic, i.e. carbon-containing dyes have important roles in nature. For example, they are responsible for transporting oxygen and other gases in the body (as part of haemoglobin) and converting solar energy into chemical energy in photosynthesis (chlorophyll). One class of artificial organic ...
Miniaturized Lab-on-a-Chip for real-time Chemical Analysis of Liquids
A fingertip-sized chip replaces bulky laboratory equipment: The possible applications are extremely diverse
01-Sep-2022
An infrared sensor has been developed at TU Wien (Vienna) that analyses the content of liquids within the fraction of a second. In analytical chemistry, it is often necessary to accurately monitor the concentration change of certain substances in liquids on a time scale of seconds. Especially in ...
Lessons from natural photosynthesis: conversion of CO₂ to raw materials for plastic!
Technology sequesters CO₂ emissions
31-Aug-2022
In plants, natural photosynthesis binds carbon dioxide (CO2) to organic compounds, which can then be converted into glucose or starch. These useful molecules can be sequestered, storing the carbon in a solid form. Artificial photosynthesis mimics this process by reducing the greenhouse gas CO2– ...
Stolen DNA strengthens immune diversity
The “theft” of foreign genetic material follows a plan
31-Aug-2022
To combat pathogens, the immune system needs an enormous number of different antibodies. In an MDC study, a group led by BIH professor Kathrin de la Rosa has now described in the journal PNAS a “stealing” mechanism that contributes to antibody diversity. A few years ago, Professor Kathrin de la ...
Economical PEF Production
Efficient titanium-based catalyst used to produce PEF, the biobased alternative to PET
30-Aug-2022
One possible replacement for drink containers made from PET is polyethylene furandicarboxylate (PEF), made from renewable resources. However, the production of the raw material for PEF from biomass is still rather inefficient. A new titanium-based photocatalyst could be about to change this, ...
Molecular Switch Controls Life Expectancy: A Single Protein Controls Aging Signals More Effectively Than In A Team
Scientists have found that the protein CHIP can control life-prolonging signals in the cell better alone than in pairs
30-Aug-2022
A new study shows that the protein CHIP can regulate the insulin receptor more efficiently alone than in a paired state. In cellular stress situations, CHIP usually appears as a homodimer - an association of two identical proteins - and primarily serves to degrade misfolded and defective ...
Innate immunity: the final touch for antimicrobial defence
A team lead by LMU immunologist Veit Hornung has identified an important intermediate step in innate immune defence
26-Aug-2022
If bacteria enter the body, it often takes just a few minutes for the innate immune system to recognise them as foreign and set the immune defence in motion. Receptors of the immune system that recognise bacterial cell wall components play a central role in this process. An important immune ...

Significantly improving the "sense of smell" of molecular laser spectroscopy: Increases chances to reliably detect diseases
25-Aug-2022
Sensitive animal noses can sniff out trace particles, such as volatile organic compounds, in the ambient air. Humans, on the other hand, are developing innovative technologies for this purpose, such as optical spectroscopy. This uses laser light to detect the molecular composition of gases. It ...
New Players in the Immune Response
This discovery has consequences – for vaccination strategies as well as for immunotherapies against cancer
25-Aug-2022
Lymph nodes trigger very different immune responses – depending on which body tissue they are connected to. Special T cells are responsible for this newly discovered relation. The human body contains 600 to 800 lymph nodes, which are specialised organs that trigger immune responses. To be ...
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.
