The computational design of new proteins for biomedical or other applications involves long computing times on powerful servers. A joint team of researchers from the Max Planck Institute for Biology Tübingen and the University Hospital Tübingen has now developed and tested a new computational method to greatly speed up the necessary energy calculations. Their framework allows for a precise and efficient design of functional proteins.

Artificial cytoskeleton made of DNA for synthetic cells

The physicists Prof. Dr. Kerstin Göpfrich and Prof. Dr. Laura Na Liu want to understand life from the bottom up. They intend to do this by constructing an artificial cell. However, rather than natural protein building blocks, they are using 3D-DNA structures as construction material. The first step involved creating an artificial cell skeleton that dynamically assembles and disassembles like the biological model and can transport vesicles.

TÜV SÜD has received approval as a UK Approved Body (UKAB) for medical devices. With this approval, medical device manufacturers can implement UKCA certification for the UK market and CE certification for the European market in a time- and cost-efficient manner with TÜV SÜD.

Scientists from the German Cancer Research Center (DKFZ) and the Cambridge Stem Cell Institute have developed an AI system that recognizes and characterizes white and red blood cells in microscopic images of blood samples. The algorithm can help physicians diagnose blood disorders and is available as an open source method for research purposes.

Germany has the most active market, Southern Europe wants more variety, and people in Poland find dairy substitutes too expensive, according to a recent study by the University of Hohenheim.

Project BlindZero - 03/08/2023

Hope for patients with eye diseases: human cornea from 3D printers

Thousands of cornea transplants are performed every year. However, donors are rare and the procedure is not always without complications. Researchers at the University of Heidelberg are developing an innovative technique in the project BlindZero. It involves ‘printing’ human corneas directly onto patients’ eyes using 3D bioprinting. The reprogrammed genetically engineered cells used for this purpose are not expected to cause a rejection reaction.

Known as the power plant of the cell, mitochondria are essential to human metabolism. Human mitochondria consist of 1,300 different proteins and two fatty biomembranes. The vast majority of mitochondrial proteins are produced with a cleavable transport signal and have to be actively transported into the mitochondria.

Konstanz chemists develop mineral plastics with numerous positive properties from sustainable basic building blocks and, together with biologists, demonstrate the material's excellent microbiological degradability.

Industrial biocatalysis with enzymes is deemed to be a “game changer” in the development of a sustainable chemical industry. Enzymes can be used to synthesize an impressive range of complex molecules. Researchers of KIT have now developed a new class of materials by producing enzyme foams of tremendous stability and activity. The researchers have already filed a patent application on the process to produce enzyme foams.

Quantum sensors for exoskeletons: can quantum physics beat paralysis?

Could people suddenly be able to move again decades after being paralysed? State-of-the-art quantum sensors integrated in exoskeletons could make this possible. Technology being developed as part of the BMBF-funded NeuroQ beacon project by researchers from organisations including the Fraunhofer IAF, the Charité in Berlin and the University of Stuttgart might achieve even more: besides facilitating movement, it could also help cure paralysis.

What impacts do agrochemicals have on the ongoing global insect decline? Biologists at the University of Konstanz have found out that aversive learning is impaired in bumblebees exposed to glyphosate. Their study is published in the journal Science of the Total Environment.

Molecular biologist Professor Holger Puchta from KIT is granted funding within a Reinhart Koselleck Project by the German Research Foundation (DFG) for work on specific restructuring of plant genomes. Puchta, a pioneer of green genetic engineering, has used molecular scissors in plants for 30 years now. His new project is aimed at using the CRISPR/Cas method to freely combine genes in crops, thus making Gregor Mendel’s dream come true.

Can biosurfactants increase microbiological oil degradation in North Sea seawater? An international research team from the universities of Stuttgart und Tübingen, together with the China West Normal University and the University of Georgia, have been exploring this question and the results have revealed the potential for a more effective and environmentally friendly oil spill response.

So far, 4.2 million animal tests under the REACH chemical regulation: A study from Konstanz and Baltimore quantifies the number of animals that died for the hazard assessment of chemicals in the chemical industry.

A new study published in Nature Medicine, July 2023 has identified two novel markers for screening high-grade squamous intraepithelial lesions (HSIL), a precursor to anal cancer, from the anal microbiome of people with HIV (PWH). PWH are at a significantly higher risk of developing anal cancer. Current screening methods, such as anal cytology, have low specificity for detecting HSIL, which hinders the prevention of anal cancer.

Tumour organoids facilitate drug discovery - 20/07/2023

Drug screening for children with cancer using patient-specific miniature tumours

Standard drugs often don’t work in children and adolescents with recurrent cancer. Researchers from the Hopp Children's Tumour Centre (KITZ) and the German Cancer Research Center (DKFZ) in Heidelberg have been looking to open up new therapy options for those affected, and have cultivated individual miniature tumours from biopsy samples to test the effectiveness of a variety of drugs within a few weeks.
