Scientists demonstrate how injuries are converted to regeneration signals at the molecular level
The phenomenon of regeneration was discovered over 200 years ago in the freshwater polyp Hydra. Until now, however, it was largely unclear how the orderly regeneration of lost tissues or organs is activated after injury. In its investigations of Hydra, an interdisciplinary research team at ...
Emissions of greenhouse gases contribute significantly to global warming. Not only carbon dioxide (CO2) but also fluorine-containing gases – including so-called per- or polyfluorinated hydrocarbons, or PFCs – have a significant share in this development. Researchers at the Institute of Organic ...
Researchers identify bacterial protein that senses and rescues “stalled” ribosomes
As a molecular machine found in the cells of all organisms, the ribosome is responsible for making new proteins. It reads the blueprint for a certain protein on a messenger molecule – known as messenger RNA (mRNA) – and then converts this information into new proteins. For a number of reasons, ...
Chemists succeed in producing synthesis and complete characterisation for the first time
Silicon, a semi-metal, bonds in its natural form with four other elements and its three-dimensional structure takes the form of a tetrahedron. For a long time, it seemed impossible to achieve the synthesis and characterisation of a two-dimensional equivalent – geometrically speaking, a square. ...
Scientists achieve defect control with a new reaction pathway
The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural “imperfections” or defects. The challenge, however, is to control the number and type of these defects. In the case of carbon nanotubes – microscopically small ...
Neurobiologists decode central mechanism of degenerative processes in the brains of mouse models and develop new principle for therapeutic agents
Neurobiologists at Heidelberg University have discovered how a special receptor at neuronal junctions that normally activates a protective genetic programme can lead to nerve cell death when located outside synapses. Their fundamental findings on neurodegenerative processes simultaneously led the ...
Researchers study the formation of microtubules
Microtubules, filamentous structures within the cell, are required for many important processes, including cell division and intracellular transport. A research team led by scientists from Heidelberg University recently discovered how the spiral-shaped, modular microtubules are formed and how ...
New spectroscopic method
A new spectroscopic method now makes it possible to measure and visualise the energetic landscape inside solar cells based on organic materials. It was developed by a research team led by Prof. Dr Yana Vaynzof, a physicist at Heidelberg University. This novel visualisation technique enables ...
Researchers quantify rare CO2 variants using laser spectroscopy
For the first time it is possible to measure, simultaneously and with extreme precision, four rare molecular variants of carbon dioxide (CO2) using a novel laser instrument. It is thus able to measure the temperature during the formation of CO2-binding carbonates and carbonaceous fossils ...
One of the most important growth processes on Earth studied
So-called bifacial stem cells are responsible for one of the most critical growth processes on Earth – the formation of wood. By alternately developing into wood and bast cells, these stem cells are thus starting points for forming wood as well as generating plant bast fibres. A team 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.
