How well does the adapted Covid-19 vaccine protect?

Should I get another booster? And if so, which vaccine should be used?


These questions are asked by many citizens who have received the basic immunization consisting of usually three individual vaccine doses. A team of researchers from the German Primate Center – Leibniz Institute for Primate Research in Göttingen and Hannover Medical School studied ...

Detecting food fraud - thanks to light quanta

Check food for content and origin more cost-effectively


When shopping in the supermarket, consumers must be able to rely on the food label. But is it always correct? In the joint project QSPEC, AMO GmbH, Laser Zentrum Hannover e.V. (LZH), AG Photonische Quantentechnologien of Leibniz Universität Hannover (LUH), TOPTICA Photonics AG, AMOtronics UG and ...

Two-billion-year-old enzyme reconstructed

Detective work explains puzzling property of modern enzymes: “The finding took us in the team completely by surprise”


Basic researchers at Leipzig University have solved a puzzle in the evolution of bacterial enzymes. By reconstructing a candidate for a special RNA polymerase as it existed about two billion years ago, they were able to explain a hitherto puzzling property of the corresponding modern enzymes. ...

A Quality-Conscious Protein

Discovery could lead to new therapeutic approaches for Alzheimer’s and other protein-misfolding diseases


Researchers have identified a new function of a well-known enzyme: the signal peptidase complex is responsible for the quality control of membrane proteins. The discovery of this new function for a key enzyme in cell biology has been published in ‘Science’ and could lead to new therapeutic ...

New Potential Mechanism for Vision Loss Discovered

Visual cells may not simply die in some diseases, but are mechanically transported out of the retina beforehand


Thanks to laboratory produced human mini-retinas, researchers were able to observe complex changes in the retina as they occur in macular degeneration. This enabled them to discover the so-called cell extrusion as a potential mechanism for neurodegenerative diseases. Visual cells in the human ...

Nanodiamonds can be activated as photocatalysts with sunlight

These inexpensive materials could be a key to further processing CO₂ into valuable hydrocarbons with sunlight in the future


Nanodiamond materials have potential as low-cost photocatalysts. But until now, such carbon nanoparticles required high-energy UV light to become active. The DIACAT consortium has therefore produced and analysed variations of nanodiamond materials. The work shows: If the surface of the ...

Neuroscientists illuminate how brain cells deep in the cortex operate in freely moving mice

This new miniature microscope is a game changer for exploring the link between neural activity and complex animal behavior


How can we see what neurons deep in the cortex are doing during behavior? Researchers at the Max Planck Institute for the Neurobiology of Behavior - caesar (MPINB) have developed a miniature microscope small enough to be carried on the head of a freely moving mouse and capable of measuring ...

Smart gifts will soon unwrap themselves

Cellulose-based actuators can be programmed and repair themselves


With the help of the high-brilliance X-ray source PETRA III, a German-Swedish research group has developed a new cellulose polymer material that can be specifically animated to move by moisture, making it an ideal base material for programmable actuators. In addition, the composite material is ...

Key factors identified for regeneration of brain tissue

Researchers demonstrate in a zebrafish model that two proteins prevent scar formation in the brain, thereby improving the ability of tissue to regenerate


Whereas cells regularly renew themselves in most endogenous tissues, the number of nerve cells in the human brain and spinal cord remains constant. Although nerve cells can regenerate in the brains of adult mammals, as LMU scientist Professor Magdalena Götz has previously shown, young neurons in ...

Green chemistry: BAM investigates pharmaceutical production without solvents and CO₂ emissions

Pharmaceutical production with mechanochemistry


The Bundesanstalt für Materialforschung und -prüfung (BAM) is developing a more sustainable process to produce active pharmaceutical ingredients in a major EU project: The pilot project is intended to demonstrate the advantages of mechanochemistry for more environmentally friendly and CO2-neutral ...
