Most powerful dual-comb spectrometer developed

System paves the way for many applications


Scientists from Hamburg and Munich developed the world's most powerful dual-comb spectrometer that paves the way for many applications in atmospheric science and biomedical diagnostics, such as early cancer detection. The work has recently been published in Nature Communications. The core part of ...

Toxoplasmosis: propagation of parasite in host cell stopped

A new method blocks the protein regulation of the parasite Toxoplasma gondii and causes it to die off inside the host cell


Toxoplasmosis is one of the most widespread zoonoses worldwide. It is an infectious disease that can be transmitted from cats to humans. People can also become infected by consuming raw or undercooked meat. Infection is particularly dangerous for pregnant women, as it can cause fetal ...

Atherosclerosis: How diseased blood vessels communicate with the brain

LMU scientists have been able to demonstrate for the first time that nerve signals are exchanged between arteries and the brain in atherosclerosis


Laboratories worldwide are carrying out research into the disease atherosclerosis. However, their focus is on atherosclerotic plaques – deposits of cholesterol, fibrous tissue and immune cells that form in the inner layer of arteries. These plaques progressively constrict the lumen of the ...

Alzheimer’s: Protective Immune Cells Active Decades Before Symptom Onset

Boosting the Brain’s Defenses Could Help Combat the Disease


In individuals with a genetic predisposition to Alzheimer’s disease, the immune cells of the brain – the “microglia” – start exerting a protective effect up to two decades before the first symptoms appear. A team from Deutsches Zentrum für Neurodegenerative Erkrankungen (DZNE) and ...

Bacterial shackle: Motility-inhibiting active substances against the gastric germ Helicobacter pylori

supplement or alternative to conventional antibiotic treatment


Helicobacter pylori, one of the most widespread bacterial pathogens, is responsible for hundreds of thousands of cases of stomach ulcers and stomach cancer worldwide every year. Due to increasing resistance of the bacterium to currently available therapeutically used antibiotics, new active ...

Highly Responsive Immune Cells Seem to be Beneficial for the Brain

New Insights into the Mechanisms of Neurodegenerative Diseases.


Findings by researchers from Germany support the view that hyperactive immune cells in the brain can have a protective effect in the course of neurodegenerative diseases. Experts from Deutsches Zentrum für Neurodegenerative Erkrankungen (DZNE), Ludwig-Maximilians-Universität München (LMU) and LMU ...

COVID-19: Breakthrough infection can substitute for a third vaccine shot

According to the study, this is possible in three constellations


According to a new study led by Ulrike Protzer, a breakthrough infection after two vaccinations achieves the same protective effect as an additional booster vaccination. According to the study by Helmholtz Munich, LMU and TUM, the decisive factor for immunity is that the immune system has had ...

Early Earth: Evolution in the abiotic world

Chemists have shown that organocatalysts go through an evolution and could have played an important role in the emergence of life


Chemical evolution took place on the early Earth before the biological one: Out of simple abiotic molecules, there emerged increasingly complex networks of chemical reactions and ultimately the first building blocks of life. Analogously to its biological counterpart, chemical evolution is based ...

Finding the invisible

Researchers have developed a method to extract more information from sequencing data


Higher organisms store their genetic material in the nuclei of cells as deoxyribonucleic acid (DNA). In a process called transcription, individual segments, the genes, are converted into messenger ribonucleic acids (mRNAs). Subsequently, the translation process produces proteins as the most ...

HIV infection: Better understanding the reservoir of virus in the body

Researchers have developed a method that allows resting human immune cells to be genetically analyzed in detail for the first time.


CD4+ T cells are important parts of the immune system and play a key role in defending the body against pathogens. As they possess a great variety of defense mechanisms against HIV in their resting state, they are infected only very rarely – but these few infected cells form a latent reservoir ...
