Wolves prefer to feed on the wild side
Research team studies feeding behaviour of wild predators in Mongolia When there is a choice, wolves in Mongolia prefer to feed on wild animals rather than grazing livestock. This is the discovery by a research team from the University of Göttingen and the Senckenberg Museum Görlitz. Previous studies had shown that the diet of wolves in inland Central Asia consists mainly of grazing livestock, which could lead to increasing conflict between nomadic livestock herders and wild predatory animals like wolves.

Artificial intelligence deciphers genetic instructions
Deep learning algorithms reveal the rules of gene regulation With the help of artificial intelligence (AI) a German-American team of scientists deciphered some of the more elusive instructions encoded in DNA. Their neural network trained on high-resolution maps of protein-DNA interactions uncovers subtle DNA sequence patterns throughout the genome, thus providing a deeper understanding of how these sequences are organized to regulate genes.

Cloudy eyes caused by protein imbalance
Cataracts: new model explains origins of the eye condition Cataracts are the most common eye ailment in humans. However, the exact processes leading to this condition are not fully understood. A team of researchers headed by the Technical University of Munich (TUM) has now discovered that the composition of the protein solution plays a decisive role.

"Living Fossil" in the Namib Has Different Subspecies
A family of Welwitschia already inhabited Earth 112 million years ago. A research team in the Department of Biology at Universität Hamburg has now used short DNA sequences to discover that the only still-living species of Weltwitschia mirabilis has different subspecies. The findings were published in the journal Scientific Reports.

When hyperactive proteins trigger illnesses
Researchers find trigger for autoimmune diseases and cancer of the lymph node Autoimmune diseases, in which the body's own immune system attacks healthy tissue, can be life-threatening and can impact all organs. A research team at the Technical University of Munich (TUM) has now found a possible cause for these self-destructive immune system attacks: a hyperactive RANK protein on the surface of B cells.

Immune cells attack synapses
Inflammation causes cerebral cortex dysfunction in multiple sclerosis Damage to the brain gray matter plays an important role in the progression of multiple sclerosis. A team of neuroscientists has now shown that the cause are inflammatory responses that lead to synapse loss, reducing neuronal activity.

How plants produce defensive toxins without harming themselves
Plants produce toxic substances to defend themselves against herbivores. In a new study, scientists from the Max Planck Institute for Chemical Ecology in Jena and the University of Münster were able to describe in detail the biosynthesis and exact mode of action of an important group of defensive substances, the diterpene glycosides, in wild tobacco plants.

A fly’s eye view of evolution
Research team led by Göttingen University investigates molecular basis of eye size variation in insects The fascinating compound eyes of insects consist of hundreds of individual eyes known as -facets-. In the course of evolution, an enormous variety of eye sizes and shapes has emerged, often representing adaptations to different environmental conditions.

Muscling RNA Polymerase Off the DNA
Researchers elucidate a unique molecular mechanism for efficient gene expression in pathogenic bacteria No 256/2020 from Dec 18, 2020 Three international research teams, including a consortium coordinated at Freie Universität Berlin, find that a motor protein, called HelD, acts like a "molecular bully" to pry the central enzyme of transcription, RNA polymerase, away from the DNA template, setting it free for the continued production of genetic messages.

Variety: spice of life for bumble bees
The yield and quality of many crops benefit from pollination, but it isn-t just honey bees that do this work: bumble bees also have a role. However, placing honey bee or bumble bee colonies next to the field does not guarantee that they will visit the desired plants since there may be other plant species flowering at the same time that prove more attractive.

Correctly Delivered and Integrated: How Proteins Find Their Place in the Cell
Heidelberg Researchers determine the three-dimensional architecture of a molecular machine that inserts essential proteins into biomembranes Over a quarter of all proteins in a cell are found in the membrane, where they perform vital functions. To fulfil these roles, membrane proteins must be reliably transported from their site of production in the cell to their destination and correctly inserted into the target membrane.

How epithelial cells ward off viruses
The cytosolic sensor NLRP1 identifies viruses as non-self and triggers inflammatory responses The ability to differentiate between self and potentially harmful non-self is vital for the integrity and survival of organisms. In most organisms, the so-called innate immune system is responsible for the recognition of such intruders.

Researchers call for greater consideration of soil biodiversity and its ecological functions in developing international conservation strategies No 008/2021 from Jan 15, 2021 The soil is home to a quarter of all known species. In fact, life above ground wouldn't be possible without the soil and its countless inhabitants.

Emotional headlines have an impact regardless of the credibility of the source
New HU study on the influence of "fake news" on the brain Neurocognitive studies by researchers at the Humboldt-Universität zu Berlin (HU) show that headlines with emotional content influence our judgments about other people even when we consider the media source to be untrustworthy. Rumours, half-truths and misinformation can be consumed and shared non-stop online and have an enormous reach.
