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.

Spread of black rats was linked to human historical events
Spread of black rats was linked to human historical events
New research reveals how the black rat colonised Europe in the Roman and Medieval periods New ancient DNA analysis has shed light on how the black rat, blamed for spreading Black Death, dispersed across Europe - revealing that the rodent colonised the continent on two occasions in the Roman and Medieval periods.

Sweet spots in the sea
Sweet spots in the sea
Scientists from the Max Planck Institute for Marine Microbiology now report that seagrasses release large amounts of sugar, largely in the form of sucrose, into their soils - worldwide more than one million tons of sucrose, enough for 32 billion cans of coke.

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.

Rapid diagnosis instead of a long odyssey
MHH Human Genetics: Whole-genome sequencing to bring the cause of rare diseases in critically ill children to light at an early stage About four million people in Germany suffer from one of the many different rare diseases (SE) - especially seriously ill children who require intensive medical treatment.

When male bees don't get lucky
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.

New discoveries about the origin of the brain’s immune system
Important immune cells in the brain's blood vessels do not mature until after birth What gets into the brain and what doesn't is strictly regulated. Researchers at the Faculty of Medicine at the University of Freiburg have now studied phagocytes that coat the blood vessels in the brain and reinforce the blood-brain barrier.

The internal compass: a modular map in the brain
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.

New approach against chronic inflammation
New approach against chronic inflammation
Researchers at the University of Bonn are treating mice with so-called "nanobodies" Researchers at the Universities of Bonn and Sao Paulo have succeeded in mitigating chronic inflammation in mice using customized "mini-antibodies." These nanobodies enabled them to dissolve molecular complexes in tissue that normally activate the immune system.

Bean cultivation in diverse agricultural landscapes encourages bees and increases yields
Bean cultivation in diverse agricultural landscapes encourages bees and increases yields
Researchers led by the University of Göttingen study bee behaviour and yield development Pollination by insects is essential for the production of many food crops. The occurrence of pollinators such as bees depends on whether nesting sites and sufficient food are available. If these conditions are lacking, the pollinators also fail to appear and the yield of flowering arable crops such as field beans and rape suffers.

How mechanical stimuli trigger cellular signalling
International GPCR research collaboration deciphers structure of active receptors Breathing, seeing, hearing - the family of G protein-coupled receptors (GPCRs) is involved in a variety of physiological processes and is also the cause of diverse diseases. As has now been discovered by a team of scientists led by Professor Ines Liebscher from Leipzig University, some members of the GPCR family respond to mechanical stimuli.

High-yielding maize and rice
High-yielding maize and rice
At the beginning of the development of useful and cultivated plants by humans about 10,000 years ago was the domestication of wild plants. From the multitude of wild plants in a region, humankind selected those that apparently possessed special properties useful to them, e.g. cereal plants whose seeds remain on the plant longer instead of falling out, or those plants that have more or larger seeds.

How Herpesviruses Awaken
How Herpesviruses Awaken
Dormant herpesviruses induce their reactivation via a previously unknown cellular mechanism mediated by a viral microRNA. Würzburg researchers show this in the journal "Nature". Eight different herpes viruses are known to date in humans. They all settle down permanently in the body after acute infection.

Fish can calculate
Researchers at the University of Bonn publish an unexpected finding Cichlids and stingrays can perform simple addition and subtraction in the number range of one to five. This has been shown in a recent study by the University of Bonn, which has now been published in the journal Scientific Reports. It is not known what the animals need their mathematical abilities for.

Origins of the Avars elucidated with ancient DNA
Origins of the Avars elucidated with ancient DNA
Multidisciplinary research team sheds light on the 1,400-year-old mystery about the genetic origins of the Avar elite Less known than Attila's Huns, the Avars were their more successful successors. They ruled much of Central and Eastern Europe for almost 250 years. We know that they came from Central Asia in the sixth century CE, but ancient authors and modern historians debated their provenance.
