When macrophage digestion goes wrong

If a secretion in the lungs’ alveoli is not cleared regularly, breathing difficulties can develop.

20-Sep-2022

In a study published in Science Immunology, a team led by Alexander Mildner and Achim Leutz has now explained the pivotal role of the transcription factor C/EBPb in this process. The exchange of gases between the air we breathe and our blood takes place via alveoli – tiny air sacs in our lungs. ...

Pushing the boundaries of chemistry: Properties of heaviest element studied so far measured

Superheavy element 114 (flerovium) is a volatile metal

20-Sep-2022

An international research team has succeeded in gaining new insights into the chemical properties of the superheavy element flerovium — element 114 — at the accelerator facilities of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt. The measurements show that flerovium is the most ...

Young genes adapt faster than old ones

Findings demonstrate how gene evolution occurs as an “adaptive walk” through time

16-Sep-2022

A new study from the Max Planck Institute for Evolutionary Biology in Plön and the University of Sussex in the UK shows that the age of a gene determines how fast they adapt. These findings demonstrate how gene evolution occurs as an “adaptive walk” through time. New species arise and evolve ...

Thriller in the bacterial kingdom

Who would have thought it of bacteria: they are capable of sneaking up on other microorganisms to kill and eat them

15-Sep-2022

Bacteria have a variety of survival strategies to ensure a sufficient food supply in their densely populated habitats. Certain species of bacteria kill microorganisms of another species, decompose their cells and absorb them as nutrients. The exact mechanism of this process is largely unknown. A ...

3D printed surfaces inspired by nature

Biologically inspired structural colours for anti-counterfeiting applications

14-Sep-2022

Scientists can use laser radiation to print tiny structures with high precision. This approach enables them to mimic the superpowers of animals and plants and makes them accessible for engineering applications. To survive in extreme habitats, many animals and plants have developed brilliant ...

A new era of early cancer detection with blood test may change cancer screening paradigms

New tests can detect common cancer signal across over 50 types of cancer from tumour DNA in blood

14-Sep-2022

Cancer doctors, care providers and payers need to get ready for a major shift in early cancer detection that will affect almost every stage of cancer diagnosis and treatment. New data supporting the accuracy of multi-cancer early detection (MCED) blood testing (1), presented at the ESMO Congress ...

A New Tool for Cryo-Electron Microscopy

New method that combines cryo-EM with a method otherwise used in materials research

12-Sep-2022

Researchers at Forschungszentrum Jülich and Heinrich Heine University Düsseldorf led by Prof. Dr. Carsten Sachse are using cryo-electron microscopy, or cryo-EM for short, to make biomolecules visible at the atomic level. In a paper now published in the journal Nature Methods, they present a new ...

Organic thin-film sensors for light-source analysis and anti-counterfeiting applications

As integrated components, the thin-film sensors could eliminate the need for external spectrometers in the future

07-Sep-2022

In a recent publication in the scientific journal “Advanced Materials”, a team of physicists and chemists from TU Dresden presents an organic thin-film sensor that describes a completely new way of identifying the wavelength of light and achieves a spectral resolution below one nanometer. As ...

From Wound Healing to Regeneration

Scientists demonstrate how injuries are converted to regeneration signals at the molecular level

07-Sep-2022

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 ...
