Lung cancer: When radiation does not work
Lung cancer: When radiation does not work
Some lung tumors do not respond to radiation therapy. This effect can be reversed by blocking an enzyme in the tumor cells, as a Würzburg research team reports. Lung cancer is the most common cancer in the world, with 2.2 million new cases and around 1.8 million deaths in 2020 alone. While knowledge about the disease has improved considerably and new therapeutic strategies can prolong the lives of previously incurable patients, the figures clearly show that the mortality rate is still far too high.

A step on the way to better therapies against viruses
A step on the way to better therapies against viruses
Researchers from the MHH and RESIST show how a cell protein of the innate immune response prevents the multiplication of herpes viruses Most body cells can defend themselves against viruses after they have been activated by the body's own messenger substances (interferons). This happens with the help of proteins that recognise invading virus components and interfere with virus replication.

Life in the earth's interior as productive as in some ocean waters
Life in the earth’s interior as productive as in some ocean waters
Microorganisms in aquifers deep below the earth's surface produce similar amounts of biomass as those in some marine waters. This is the finding of researchers led by the Friedrich Schiller University Jena and the German Centre for Integrative Biodiversity Research (iDiv), both Germany. Applying a unique, ultra-sensitive measurement method using radioactive carbon, they were able to demonstrate for the first time that these biotic communities in absolute darkness do not depend on sunlight.

Shining some light on the obscure proteome
Mass-spectrometry based proteomics is the big-data science of proteins that allows to monitor the abundances of thousands of proteins in a sample at once. It is therefore a particularly well suited readout to discover which proteins are targeted by any small molecule. An international research team has investigated this using chemical proteomics.

Signaling pathway in the brain to control food intake decoded
Binge eating bye bye: Signaling pathway in the brain to control food intake decoded A group of researchers has found a completely new approach to treating eating disorders. The scientists have demonstrated that a group of nerve cells in the hypothalamus (known as AgRP, agouti-related peptide neurons) control the release of endogenous lysophospholipids, which in turn control the excitability of nerve cells in the cerebral cortex, stimulating food intake.

Mass spectrometry-based draft of the mouse proteome
Proteins control and organize almost every aspect of life. The totality of all proteins in a living organism, a tissue or a cell is called the proteome. Using mass spectrometry, researchers at the TUM School of Life Sciences characterize the proteome, or protein complement of the genome, in important model organisms.

Defects in quartz crystal structure reveal the origin of dust
Defects in quartz crystal structure reveal the origin of dust
Global warming and a progressively drier climate in many parts of the world are causing more dust storms. To predict how these storms are caused, researchers are looking into the past to understand where the dust came from, for how long, and over what distances it was transported. An international research team led by Dr. Aditi K. Dave and Professor Kathryn Fitzsimmons from the Department of Geosciences at the University of Tübingen, along with colleagues from Romania, Brazil, Kazakhstan and Tajikistan, have now developed a new method of doing this.

Importance of Selenium in the Opening Stages of Protein Synthesis
An international team of researchers with members from Freie Universität Berlin has made an important contribution to our understanding of the essential trace element selenium. The team was able to demonstrate how selenocysteine is incorporated into the proteins of eukaryotes. Using a specialized cryo-electron microscope, the researchers from Charité - Universitätsmedizin Berlin, the Max Planck Institute for Molecular Genetics, Rutgers University, New Jersey, USA, and the University of Illinois, Chicago, USA, succeeded in visualizing the first steps in selenoprotein synthesis.

Long-sought tetra-neutron discovered
Long-sought tetra-neutron discovered
After 60 years of unsuccessful searches, an international research team has discovered a neutral nucleus for the first time - the tetra-neutron. The collaboration succeeded in creating an isolated four-neutron system with low relative kinetic energy in a volume equivalent to an atomic nucleus. The building blocks of atomic nuclei are the nucleons, which come in two types, the neutral neutrons and the positively charged protons - the two so-called isospin states of the nucleon.

Default options facilitate faster carbon offsetting in air travel
Study with participation of University of Cologne economist finds that many air travellers more readily choose faster, but more expensive carbon offsetting options online if selecting a slower option requires action. However, the readiness to do so decreases the greater the gap between the most and the least expensive option gets / publication in 'Nature Human Behaviour' The defaults on a carbon offsetting website can cause a large percentage of customers to select faster CO2 compensation, even if this entails higher costs.
