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 pharmaceutical production.

Using animal-free methods to assess the hazard potential of chemicals to the nervous system of unborn children? An international research team including toxicologists from Konstanz and Düsseldorf has developed a testing battery based on human cells that has the potential to replace traditional methods for assessing developmental neurotoxicity.

With its "Proof of Concept" grants, the European Research Council ERC supports scientists in further developing the commercial potential of their research results. Nina Papavasiliou from the DKFZ is now receiving the prestigious grant for the second time: she wants to advance the development of a "molecular delivery service" that ensures that therapeutic genes reach the right address in the body in a targeted manner.

Cancer cells often grow in environments that are low in nutrients, and they cope with this challenge by switching their metabolism to using proteins as alternative "food". Building on genetic screens, an international team of scientists could identify the protein LYSET as part of a pathway that allows cancer cells to make this switch. Their findings are now published in the journal Science.

Bakteriocins - 24/05/2022

New antibiotic alternatives from soil bacteria

Bacteria are not the greatest of friends among themselves: many release antimicrobial substances into their environment in order to gain an advantage in their ecological niche. Researchers at the University of Ulm are making use of such bacteriocins by creating a genetically modified soil bacterium that can be used as a biotechnological platform organism to produce alternatives to antibiotics in pure form and in large quantities. The fact this…

Certain childhood tumors have an extreme need for amino acids. Scientists at the Hopp Children's Cancer Center Heidelberg (KiTZ), the German Cancer Research Center (DKFZ), the University of Heidelberg, and HI-STEM* gGmbH have now discovered the molecular mechanisms underlying this and how the cancer cells could be turned off.

Laboratory studies of lung tissue usually require the removal of large amounts of human or animal tissue. Now scientists from the University of Freiburg’s Faculty of Medicine have succeeded in collaboration with American researchers in generating tiny quantities of lung tissue, so-called organoids, from just a few body cells in the lab.

In the field of optogenetics, scientists investigate the activity of neurons in the brain using light. A team led by Prof. Dr. Ilka Diester and Dr. David Eriksson from the Optophysiology Laboratory at the University of Freiburg has developed a new method to simultaneously conduct laminar recordings, multifiber stimulations, 3D optogenetic stimulation, connectivity inference, and behavioral quantification on brains.

Biosensor for whole blood and exhaled breath analysis - 02/02/2022

Antibiotic detection from whole blood or exhaled breath possible

Incorrectly dosed antibiotics are not only dangerous for patients, but also often the cause of resistant strains of bacteria. Researchers at the University of Freiburg have developed a biosensor to determine the effective amount and thus enable personalised therapy. The biosensor works by rapidly determining small amounts of the substances directly from whole blood or exhaled breath.

Researchers use epigenetic factors to investigate the role of stress in the development of tumor diseases. Experts believe that stress plays a major role in the development of tumors. One occupational group, for example, that experiences extreme stress over a short period of time is astronauts.

3R-Center - 18/08/2021

Putting alternatives to animal testing into practice

Animal experiments are still central to biomedical research. However, it has become increasingly clear that not all of them are absolutely necessary. Alternative techniques exist. The new 3R-Netzwerk Baden-Württemberg is now seeking to promote these more vigorously - and improve animal welfare in cases where alternatives to animal testing are not available.
