A brain network for social attraction
A brain network for social attraction
Specialized nerve cells in the zebrafish visual system enable recognition of conspecifics Humans are famously social animals. But they are not alone in their tendency to team up with other individuals of the same species (conspecifics) to reach their goals. In fact, herds of mammals, flocks of birds, or shoals of fish are abundantly observed in nature.

Molecular Feedback-Loop for Plant Growth
Molecular Feedback-Loop for Plant Growth
Scientists discover previously unknown mechanism that regulates the growth hormone auxin Plant growth is not a uniform process: Plants grow in length at the shoot and root tip in particular, while in other places they form new leaves or flowers. These different processes must be coordinated with each another and at the same time react to external influences such as temperature and light.

Sperm are masters of tetris packing
Sperm are masters of tetris packing
Study sheds light on the process that plays a central role During sperm production, an enormous amount of DNA has to be packed into a very small space without breaking anything. A central role is played by certain proteins around which the DNA thread is wrapped - the protamines. A recent study by the University of Bonn provides new insights into this important mechanism.

Key to global food security?
Key to global food security?
International research team investigates genetic yield gaps in wheat Exploiting the genetic yield gap in wheat could significantly improve global food security. This is one of the key findings of an international study on yield gaps in wheat, in which the University of Göttingen was involved. The study, which uses a novel process-based modeling approach, also suggests that global wheat production could be doubled if wheat genotypes were better adapted to their target environment.

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.

Shining some light on the obscure proteome
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.

Using light to activate mRNA: Biochemists use new tool to control mRNA by means of light
DNA (deoxyribonucleic acid) is a long chain of molecules composed of many individual components, and it forms the basis of life on Earth. The function of DNA is to store all genetic information. The translation of this genetic information into proteins - which an organism needs to function, develop and reproduce - takes place via mRNA (messenger ribonucleic acid).
