How faulty mRNA is detected and destroyed
Two similar proteins can stand in for each other in the quality control mechanism of defective mRNA. This has redefined the distribution of protein tasks / publication in 'The EMBO Journal'. Scientists led by Professor Dr Niels Gehring at the Institute for Genetics at the University of Cologne have investigated two similar proteins, UPF3A and UPF3B, which are involved in the quality control mechanism 'nonsense-mediated mRNA decay' (NMD).

'Growing end' of inflammation discovered
’Growing end’ of inflammation discovered
Researchers from the Universities of Bonn and Cologne observe how the danger sensor NLRP3 lengthens itself like a thread Redness, swelling, pain - these are signs of inflammation. It serves to protect the body from pathogens or foreign substances. Researchers from the Universities of Bonn and Cologne were able to show that inflammatory reactions of an important sensor protein proceed in a specific spatial direction.

A repair program for the heart
Following a heart attack, the human body is incapable of repairing lost tissue due to the heart's inability to generate new muscle. However, treatment with heart progenitor cells could result in the formation of functional heart cells at injured sites. This new therapeutic approach is introduced by an international team.

Rare discovery: How a gene mutation causes higher intelligence
Rare discovery: How a gene mutation causes higher intelligence
When genes mutate, this can lead to severe diseases of the human nervous system. Researchers at Leipzig University and the University of Würzburg have now used fruit flies to demonstrate how, apart from the negative effect, the mutation of a neuronal gene can have a positive effect - namely higher IQ in humans.

Animal research: influence of experimenters on results less strong than expected
Animal research: influence of experimenters on results less strong than expected
For more than ten years now, scientists have been discussing the so-called reproducibility crisis: often, scientific findings cannot be reproduced at a later time and/or in other laboratories, although the studies are carried out under highly standardised conditions. Thereby, standardisation includes for example the use of genetically identical animals, keeping the animals in identically equipped cages, and carrying out the experiments in always the same way.

Cell division in moss and animals more similar than previously thought
Cell division in moss and animals more similar than previously thought
German-Japanese research team from Universities of Freiburg and Nagoya identifies what determines the site of cell division in plants For a new plant to grow from a seed, cells need to divide numerous times. Daughter cells can each take on different tasks and sometimes vary in size. How plants determine the plane of cell division in this process, known as mitosis, is being researched by Ralf Reski and Dr. Elena Kozgunova from the University of Freiburg in a joint effort with Prof. Dr. Gohta Goshima from Nagoya University.

Research team decodes human genome
Research team decodes human genome
"A big puzzle": How an international consortium has now completely decoded the human genome The human genome is like a puzzle - but a difficult one to solve: This puzzle has more than three billion pieces. And as if that were not challenging enough, the puzzle is made even more confusing by similar pieces as well as patterns that repeat themselves.

The fungal effector Rip 1 suppresses maize host defense responses
The fungal effector Rip 1 suppresses maize host defense responses
Coevolution between pathogens and host plant immune systems shapes a multifaceted network of interactions that remain phenotypically unrecognised and functionally elusive unless single players are depleted from the system. The maize-colonising fungus Ustilago maydis secretes a complex effector blend in order to suppress defence and redirect host metabolism in its favour.

Love is in the air
Love is in the air
More blood flow to the genitals, an increased pulse and dilated pupils: These physical characteristics reveal that a person is sexually aroused. But lust can also be detected in the breath, as a study of an international research team has now shown. According to the study, a characteristic signature of volatile molecules is found in the breath of sexually aroused people.

When male bees don’t get lucky
04/25/2022 Do pesticides have anything to do with the decline in bee populations? A research team led by the University of Würzburg has investigated - and found a connection between fenbuconazole and the insects' mating behavior. Bees are among the most important pollinators on earth. They pollinate not only plants with beautiful flowers, but also many crops.

A Low-Calorie Diet Alters the Gut Microbiome and Delays Immune Aging
A Low-Calorie Diet Alters the Gut Microbiome and Delays Immune Aging
Around 2 billion people worldwide are overweight. Obesity increases the risk of developing high blood pressure, heart attack or type 2 diabetes mellitus and can cause inflammation in the body that weakens the immune system through an accumulation of specific memory T and B cells. This process is called immune senescence, an age-related change in the immune system.

How equal charges in enzymes control biochemical reactions
How equal charges in enzymes control biochemical reactions
Research team led by Göttingen University describes fundamental principle of enzyme catalysis It is well known in physics and chemistry that equal charges repel each other, while opposite charges attract. It was long assumed that this principle also applies when enzymes - the biological catalysts in all living organisms - form or break chemical bonds.

The internal compass: a modular map in the brain
Landmarks like a church steeple or a yellow house on the corner play an important role in the ability to navigate. But so does an internal compass, thought to be supported by specialized neurons in the brain - called -head-direction- cells. These neurons respond to direction, and there are still many unsolved puzzles as to how they work.

Flying into a clean and safe future
Flying into a clean and safe future
In the race to avoid runaway climate change, two renewable energy technologies are being pushed as the solution to powering human societies: wind and solar. But for many years, wind turbines have been on a collision course with wildlife conservation. Birds and other flying animals risk death by impact with the rotor blades of turbines, raising questions about the feasibility of wind as a cornerstone of a global clean energy policy.

Enzyme prevents brain activity from getting out of control
Mechanism identified at University of Bonn alters the coupling of nerve cells The brain has the ability to modify the contacts between neurons. Among other things, that is how it prevents brain activity from getting out of control. Researchers from the University Hospital Bonn, together with a team from Australia, have identified a mechanism that plays an important role in this.
