Algorithm predicts which students will drop out of Math courses
In the subjects of science and technology, engineering and mathematics - known collectively as STEM subjects - up to 40 percent of students drop out of their studies in the entry phase. A research team from the University of Tübingen's Methods Center at the Faculty of Economics and Social Sciences has now developed a statistical method that can be used to predict on average eight weeks in advance whether students will terminate their studies.

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.

Bones, constructed like prestressed concrete
Bones, constructed like prestressed concrete
Incorporating various minerals in collagen puts these composite materials under stress and makes them particularly hard and strong What engineers discovered only about 100 years ago has been used by nature for as long as vertebrates have existed. Just as steel wires under strain increase the fracture resistance of prestressed concrete, bones become particularly hard and strong because their collagen fibres are under stress due to embedded mineral nanoparticles.

Vaccination campaign messages often prove ineffective
Vaccination campaign messages often prove ineffective
Conventional vaccination campaign messages often miss their targets. A study in eight European countries shows that information on the benefits of vaccines can even reduce the willingness to get immunized. The researchers also looked into the factors that influenced the impact of messages, including low health literacy.

Forest plants now flower a week earlier than a century ago
Early-flowering plants in European forests today start their flowering season on average a week earlier than they did a hundred years ago. This is reflected by herbarium specimens, as Dr. Franziska Willems and Professor Oliver Bossdorf from the Institute of Evolution and Ecology at the University of Tübingen, together with Professor J. F.

Liver fibrosis: the fatal signalling pathway
MHH research team clarifies how liver inflammation and scarring of liver tissue are connected At least five million people in Germany suffer from liver disease. Fibrosis, the pathological proliferation of connective tissue, plays an important role in many complications of chronic liver problems. Activated hepatic stellate cells (HSCs) are massively involved in this tissue remodelling.

Meat substitutes: Environment does not motivate consumption
Meat substitutes: Environment does not motivate consumption
Animal welfare and health aspects, on the other hand, promote the use of meat alternatives People who have a critical attitude toward factory farming or who pay attention to their health in everyday life are more likely to turn to meat substitutes. Concern for the environment, on the other hand, plays no role in this decision.

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.

Atomic terahertz vibrations generate soliton molecules
Atomic terahertz vibrations generate soliton molecules
Stable packets of light waves - called optical solitons - are emitted in ultrashort-pulse lasers as a chain of light flashes. These solitons often combine into pairs with very short temporal separation. Introducing atomic vibrations in the terahertz range, researchers at the Universities of Bayreuth and Wroclaw have now solved the puzzle of how these temporal links are formed.

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.
