Where quantum computers can score
Where quantum computers can score
The travelling salesman problem is considered a prime example of combinatorial optimization problems. Now a Berlin team led by theoretical physicist Jens Eisert from Freie Universität Berlin has shown that a certain class of such problems can actually be solved better and much faster using quantum computers than with conventional methods.

Newly discovered receptor influences gut development in fruit flies
Newly discovered receptor influences gut development in fruit flies
Adhesion GPCRs are a group of G protein-coupled receptors associated with many bodily functions and diseases in humans. Scientists at Leipzig University have discovered a new receptor - which they have named "mayo" - and found that it influences the development of the small intestine and heart function in fruit flies, and that these phenomena may also be relevant in humans.

Same Target, Different Effects
Same Target, Different Effects
Even if they attack the same target in the bacterial cell, the cellular response to different antibiotics can vary. There is an urgent need for new antimicrobial strategies to keep pathogens in check. This applies specifically to Gram-negative bacteria, which are protected from antibiotic intervention by a thick second membrane.

Do school grades influence parental support?
The Max Planck Institute for Demographic Research in Rostock, Germany, has researched parents' support behavior in relation to school grades. The study shows that low-income families support their children equally regardless of grades, while parents from higher income groups tend to give more support to children with lower grades.

Plant identification via app enables phenological monitoring
Plant identification via app enables phenological monitoring
Researchers at the Max Planck Institute for Biogeochemistry in Jena and the TU Ilmenau have shown that plant observations collected using plant identification apps such as Flora Incognita can provide information about the developmental stages of plants - both on a small scale and across Europe. "The snowdrops have never bloomed as early as this year, have they?" Many people who walk through nature with their eyes open are sure to have asked themselves these or similar questions.

Interaction between metabolic health and healthy aging supported
Ribosomes, the "translation factories" of the cell, are cellular organelles that play a central role in protein synthesis, a vital process for all living organisms. These tiny structures themselves consist of ribonucleic acid (RNA) and proteins and are essential for the survival and normal functioning of the cell, as the proteins they produce are required for nearly all cellular processes, including structure, function, and regulation.

Redefining Quantum Machine Learning
New study from team of quantum physicists at Freie Universität Berlin challenges traditional understanding of quantum machine learning Machine learning is a branch of artificial intelligence (AI) and computer science that focuses on the use of data and algorithms to allow computers to learn without explicitly being programmed.

Stronger than Nature: Optimised Radicals as Potential Novel Catalysts
Research team redesigns phenoxyl radicals with improved oxidation capacity in the lab. Nature uses enzymes for various metabolic processes. These biological catalysts are extremely efficient. Biomimetic catalysts based on inexpensive starting materials from the laboratory that can reproduce the efficiency of the natural enzymes and can function at ambient conditions are therefore of great interest to research and industry.

Shopping study in a virtual supermarket
A study by the University of Bonn shows: Banners with information on animal welfare have no influence on purchasing behavior How can we encourage consumers to pay more attention to animal welfare aspects when they purchase meat? It now appears that this cannot be achieved solely by making the animal husbandry labels more visible.

Included in the thought? New studies on the generic masculine
Included in the thought? New studies on the generic masculine
The generic masculine generally emphasizes the masculine side. The fact that all genders are of course meant does not change this. This is shown by a new study by Würzburg psychologists. It is a crux with the generic masculine in German: if a group is made up of 99 female professors and only one male professor, it would be grammatically correct to speak of "the professors" in this case.

A giant called MIMAS in the cell power plants
Freiburg research team discovers mega-protein complex with surprising properties in mitochondria Mitochondria provide the majority of the body's energy supply and are considered the power plants of the cells. The energy comes from cellular respiration, in which metabolic products are burned in the inner mitochondrial membrane.

The right approach increases willingness to donate stem cells
The right approach increases willingness to donate stem cells
Every year, more than 20,000 people in Germany die from blood cancer. In children, blood cancer is even the most common type of cancer. Donations of stem cells from bone marrow or blood increase the chance of survival for people suffering from leukemia or other forms of blood cancer. However, it can take years between the registration of those willing to donate and their actual donation.

How surface roughness influences the adhesion of soft materials
Research team discovers universal mechanism that leads to adhesion hysteresis in soft materials Adhesive tape or sticky notes are easy to attach to a surface, but are difficult to remove. This phenomenon, known as adhesion hysteresis, can be fundamentally observed in soft, elastic materials: Adhesive contact is formed more easily than it is broken.

Forestry in a changing climate: extreme weather increases investment risk
Research team investigates adaptation strategies from a forestry perspective . Climate change is altering our forests. Increased storms and drought have significant consequences for ecosystems and their sustainable use. Forests are important for wood production, carbon storage and local recreation, for example.

Learning from conspecifics
Chimpanzees that are unable to figure out a complex puzzle on their own, are capable of learning the solution from other chimps that were trained to solve it. This is the conclusion reached by an international research team from Utrecht University, the University of St Andrews and the Max Planck Institute for Evolutionary Anthropology as part of a study conducted with groups of chimpanzees in Zambia.

Early life adversity leaves long-term signatures in baboon DNA
Early life adversity leaves long-term signatures in baboon DNA
Study shows multiple pathways connect early life adversity to later life health Early experiences in an animal's life can have a significant impact on its capacity to thrive, even years or decades later, and DNA methylation may help record their effects. In a study of 256 wild baboons, researchers from the Max Planck Institute for Evolutionary Anthropology and Duke University found that resource limitation during early life was associated with many differences in DNA methylation, a small chemical mark on the DNA sequence that can affect gene activity.
