Model-based recursive partitioning has emerged as a powerful technique for identifying subgroups of individuals with distinct patterns of relationships between variables. While traditional approaches have focused on structural equation models (SEMs) for cross-sectional data, recent advancements have extended this methodology to dynamic SEMs for longitudinal data. The Psychological Research Methods Group (Manuel Völkle) has developed a novel approach called score-based CT-SEM trees, which enables the analysis of data with irregular sampling plans. Find out more in their Chapter in Dependent Data in Social Sciences Research.

Recurrence Quantification Analysis (RQA) is a powerful technique for analyzing the nonlinear dynamics of time series data. However, traditional RQA is limited to univariate time series. To address this limitation, Multidimensional RQA has been developed to analyze the joint dynamics of multivariate time series. The Social and Organizational Psychology Group (Ursula Hess) and the Psychological Assessment Group (Matthias Ziegler) developed a novel extension of Multidimensional RQA, called Lagged Multidimensional RQA, which allows for the investigation of relationships between different variables within a multivariate time series. Find out more about the utilization of Lagged Multidimensional RQA in analyzing joint action research data, specifically focusing on the shared dynamics between facial expressions and heart rate in their Psychological MethodsArticle!

Most of us have experienced it at least once in life - a devastating breakup. Romantic breakups can have significant emotional and psychological consequences. While research has consistently shown that men tend to suffer more from these separations than women, the underlying reasons for these gender differences remain unclear. The Developmental and Educational Psychology Group (Denis Gerstorf) investigated the gender-specific responses to romantic breakups, focusing on factors such as initiation of separation, well-being, loneliness, and desire for a new partner. If you are curious about how gender and age affect one's ability to survive a breakup unscathed, check out their Psychology and Aging Article!

Spin-orbit interaction plays a crucial role in the behavior of electrons in condensed matter systems. Igor Sokolov investigated the dynamics of spin polarization in a two-dimensional system of spin-1/2 charged particles subject to a perpendicular magnetic field and external noise. If you are curious as well, check out his Physical Review E Article.

Most of us use them in our interactions with other individuals - some more, some less - emotional expressions! Emotion Recognition Accuracy (ERA) is a complex cognitive process influenced by both pattern matching and perspective-taking. The Assessment of Contextualized Emotions (ACE) test is a valuable tool for studying ERA which considers not only the social context and multiple emotions, it simultaneously distinguishes between accuracy (perceiving the intended emotions) and inaccuracy (perceiving additional emotions to those expressed). Using an  fMRI-compatible adaptation of ACE the Social and Organizational Psychology Group (Ursula Hess) investigated whether emotion processing is associated with distinct brain activations for single versus group-embedded facial expressions as well as the behavioral relevance of regional changes in activation in the fMRI-compatible ACE task. Find out more about the importance of cognitive bias in the assessment of social emotion perception in their Social Neuroscience Article!

Multivariate decoding techniques are widely used to study the neural basis of working memory. Encoding models offer a promising approach to understanding the tuning properties underlying these neural representations by explicitly modeling the similarity relationships between different stimuli. The Distributed Cognition and Memory Group (Thomas Christophel) set out to evaluate the effectiveness of encoding models for quantifying mnemonic representations using both simulated and real data and found that a reliable identification of the true model requires comparing the variance of two or more competing models.

In her talk ‘Collective behaviour of nematodes’ Serena Ding will talk about how C. elegans has recently emerged as a model for several striking collective behaviours such as aggregation, wurmuration, and towering. Combining the powerful experimental accessibility of this major lab model organism with the knowledge that collective phenomena are widespread and highly relevant for many nematode species, they use quantitative behavior and behavioral ecology approaches to unravel the mechanism and the function of multiple collective behaviours in ecologically relevant nematode groups.

Aphids are a significant pest of sweet pepper plants, causing damage by feeding on amino acids in the leaves. As magnesium (Mg2+) plays a crucial role in the transport of amino acids from leaves to fruits the Intensive Food Plant Systems Group (Tsu-Wei Chen) investigated whether the application of Mg2+ could reduce aphid colonization by decreasing the availability of amino acids in leaves by promoting their transfer to fruits. If you are curious whether magnesium is the key to improving the nutritional environment for the plant while simultaneously reducing the attractiveness of the leaves to aphids, check out their Scientia Horticulturae Article!

The 'Single Molecule Biophysics Course' was a five-day training program designed to eduacte its participants in Single Molecule Theory, Single Channel Recording and Single Molecule Total Internal Reflection Fluorescence (TIRF) Microscopy. It comprised the relevant theoretical background as well as practical sessions to provide a holistic training schedule.

Major Facilitator Superfamily (MFS) proteins play crucial roles in drug transport across cell membranes. In Plasmodium falciparum, the causative agent of malaria, the MFS protein PfMFSDT has been identified as a potential drug transporter. However, its functional relevance in drug resistance remains unclear. By expressing PfMFSDT in C. glabrata - a well-established model organism for studying fungal drug resistance - and analyzing its localization and drug resistance profiles, the Organic and Bioorganic Chemistry Group (Christoph Arenz) has provided important additional information on the role of PfMFSDT in conferring resistance to P. falciparum.

Confirmation bias - the tendency to favor information that confirms existing beliefs - is a well-documented cognitive bias. While it can lead to irrational decision-making, it has also been shown to improve decision-making under uncertainty. However, the impact of confirmation bias on social decision-making remains relatively unexplored. In order to investigate how confirmation bias influences collective decision-making in a social context the Collective Information Processing Group (Pawel Romanczuk) developed a computational model, which allows to conduct agent-based simulations to explore the effects of resource scarcity, group size, and bias strength on group performance.

Subdiffusive motion, characterized by slower-than-normal diffusion, is a common phenomenon in various physical systems. In this Physical Review E Review Igor Sokolov and Eugene Postnikov provide an overview about the underlying mechanisms governing subdiffusive motion in constrained environments improving the understanding of how geometric factors influence the dynamics of particles exhibiting anomalous diffusion.

Sphingolipids are ubiquitous components of membranes in mammalian cells. The most abundant sphingolipid is sphingomyelin the breakdown of which has been associated with the pathogenesis of numerous viral and bacterial pathogens and sphingomyelinases (SMases) have been linked to many widespread diseases such as depression or cardiovascular and neurodegenerative diseases. Since lipids cannot be easily fluorescently labelled as is the case with proteins, their visualization in the cell is rather difficult and as a result their contribution to the infection process is only poorly understood. To overcome this obstacle, the Organic and Bioorganic Chemistry Group (Christoph Arenz) has developed novel trifunctional sphingomyelin derivatives that make it possible to visualize both the distribution and the metabolic activity of sphingomyelin in cells. Find out more about this fantastic innovation in their Nature Communications Article!

Group hunting is a widespread strategy among various animal species, offering potential benefits such as increased hunting success and reduced individual risk. Understanding the complex interactions between predators and prey is crucial for comprehending the evolution of cooperation and social behavior. Prey movement plays a pivotal role in predator-prey dynamics. Prey often respond to predation threats by either fleeing or standing their ground, significantly influencing the costs and benefits of predator and prey strategies. The Collective Information Processing Group (Pawel Romanczuk) investigated how prey behavior affects predator strategies of striped marlin, Kajikia audax and the overall dynamics of their predator-prey interactions.

Green infrastructure (GI) plays a crucial role in enhancing urban resilience and sustainability. However, traditional GI planning often overlooks the spatial distribution of residents, leading to potential conflicts between spatial equity and equitable green exposure. The Landscape Ecology Group (Dagmar Haase) established a novel accessibility equity approach for prioritizing GI development in Zhengzhou, China, which considers various socioecological factors and population density and aims to identify areas that require greater focus on GI implementation to ensure equitable access to green spaces and associated benefits.

We encounter plants every day (hopefully at least). But have you ever looked at what plants can do at the molecular level? Unlike us, plants have different types of plastids, such as chloroplasts, which use light energy to produce O₂ from CO₂ and thus provide us with a basis for life on this planet. Plastid biogenesis and the coordination between plastid and nuclear genomes are complex processes and critical for plant development. The protein GENOMES UNCOUPLED1 (GUN1) plays a pivotal role in retrograde signaling, a process that communicates the status of plastid function to the nucleus. Despite extensive research, the molecular function of GUN1 has long remained elusive. However, investigating the function of GUN1 the Molecular Genetics Group (Christian Schmitz-Linneweber) found that the protein is involved in RNA binding and maturation, resolving long-standing controversies about its molecular function.

Although city people are less exposed to nature than rural inhabitants, there are numerous points of contact with wildlife in cities. In addition to parks and urban forests, plants and animals that have managed to settle in the city can be found in ordinary streets. Encounters with city animals in particular often leave quite an impression. Who does not remember an unexpected meeting with a fox in the city center, after which one was amazed at how unfazed this creature moves in the midst of crowds of people, cars and skyscrapers? Or the cute little hedgehog that disappeared under the hedge! But I'm sure we all remember the fat rat or racoon that almost gave us a heart attack while taking out the garbage in the evening. The Landscape Ecology Group (Dagmar Haase) investigated how the residents of various German cities perceive their encounters with distinct wild mammals in residential areas by conducting and analyzing an online survey.

Lipid droplets (LDs) are essential organelles involved in lipid storage and metabolism. In the malaria parasite Plasmodium falciparum, LDs play a crucial role in the parasite's life cycle. Despite their importance, the specific functions of LDs in P. falciparum remain relatively unexplored. The Molecular Parasitology Group (Kai Matuschewski) investigated the role of LDs in the malaria parasite's lipid metabolism by analyzing their size, composition, and dynamics throughout the parasite's life cycle. You can read more about their valuable insights into the parasite's lipid acquisition and utilization strategies and the potential of LDs as targets for new anti-malarial drugs in their Journal of Cell Science Article!

Climate change poses significant threats to human health and well-being. Understanding individual vulnerability to climate hazards is crucial for developing effective adaptation strategies. The Developmental and Educational Psychology Group (Denis Gerstorf) established a new intraindividual variability construct, called affective sensitivity to air pollution (ASAP), which measures how an individual's emotional state fluctuates in response to daily changes in air quality. Check out  in their PLOS ONE Article to find out more about ASAP and how it can help to incorporate mental health and emotional well-being into climate adaptation strategies to enhance resilience and overall human welfare.

Surface-enhanced Raman scattering (SERS) is a powerful technique used to enhance the Raman signal of molecules adsorbed on a metal surface. While traditional SERS focuses on one-photon excited spontaneous Raman scattering, recent advancements have explored nonlinear Raman processes. These processes, driven by high local fields generated by localized surface plasmon resonances (LSPRs), offer unique advantages for studying plasmon-molecule interactions and characterizing nanomaterials. In their ACS Nano Perspective, Janina Kneipp and Katrin Kneipp provide researchers can gain a deeper understanding of plasmon-molecule interactions and explore new applications in materials research, catalysis, and nanobiophotonics.

Plants are able to rapidly adapt to changing environmental conditions. One fundamental adjustment is the expression of chloroplast genes. The essential splicing factor Maturase K has been anticipated to play a generally important role in cholorplast gene regulation, but its importance has so far made it rather difficult to study its function and targets in detail. Together, the Plant Cell and Molecular Biology Group (Kerstin Kaufmann) and the Molecular Genetics Group (Christian Schmitz-Linneweber) investigated which transcripts Maturase K preferably targets and how this translates to a differential expression of functional chloroplast gene groups.

It is well known, that our gut microbiome has a great influence on our physical and mental wellbeing. Intestinal bacteria help us to break down our food, provide us with vitamins and metabolites and support our immune system. Therefore, a healthy diet and probiotics are powerful tools to modulate our general health. Also chickens are known to benefit from being fed probiotic bacteria, which is assumed to be mainly caused by modulation of the immune system. The Breeding Biology and Molecular Genetics Group (Gudrun Brockmann) investigated how these bacteria interact with  the peripheral blood mononuclear cells (PBMCs) of chickens by whole transcriptome profiling and cytokine array analysis.

As cities grow and also rural areas are to a large extend characterized by agriculture and infrastructure natural habitats for wildlife are becoming increasingly scarce. Oganisms that are able to adapt to urban conditions however can profit from the these can benefit from the diverse supply of food and shelters attracting more wildlife to the cities. This coexistence can lead to conflicts. In order to better understand which animals have a high potential for conflict and how these conflicts can best be resolved, the Landscape Ecology Group (Dagmar Haase) interviewed experts and summarized their findings in their People and Nature Article!

Developmental psychology investigates human growth and changes across the lifespan. This comprises the physical, cognitive, social, intellectual, perceptual, personality and emotional development. The developmental cascade model describes how the speed to process information increases with age (especially in our early years), which boosts the working memory, which in turn improves fluid intelligence. While these factors naturally vary from person to person also a intra-subject variability exists. The Psychological Research Methods Group (Manuel Völkle) investigated the role of intra-subject variability within the pathways that constitute the developmental cascade model.

In his talk 'Cerebral Cortex Connectomics' Moritz Helmstaedter spoke about the mapping of neuronal connectivity, which is one of the main challenges in neuroscience. Only with the knowledge of wiring diagrams is it possible to understand the computational capacities of neuronal networks, both in the sensory periphery, and especially in the mammalian cerebral cortex. The methods of the Department of Connectomics for dense circuit mapping are based on 3-dimensional electron microscopy (EM) imaging of tissue, which allows imaging nerve tissue at nanometer-scale resolution across substantial volumes, extending to more than one millimeter on the side, followed by AI-based image analysis to obtain dense connectivity maps, or connectomes. With these they have mapped local circuitry in mouse and human cortex, determining learning-related synaptic traces, inhibitory axonal development, and discovering an expanded interneuron-to-interneuron network in the human cortex. Most recently they completed the connectomic reconstruction of a cortical column. They are currently screening cortical connectomes across age, disease states and experience to obtain a deeper understanding of their relevance for individual behavioral performance and brain pathology.

While some predators compete with each other for prey, others benefit from the other, intentionally or unintentionally. Seabirds, for example, profit immensely from the presence of subsurface predators and therefore often share a habitat. However, the principle behind this phenomenon is poorly understood. The Collective Information Processing Group (Pawel Romanczuk) performed spatio-temporal analysis of drone footage to unravel the hunting behaviour of Indo-Pacific sailfish and terns and made some interesting discoveries.

We live in a world in which resources are becoming increasingly scarce while the waste we produce has taken on immense dimensions. For this reason, sustainability is a necessary key issue in various areas of business, science and politics. The circular bioeconomy concept is a new economic model that emphasizes the use of renewable and natural ressources and the minimization of waste production, and thus attempts to meet the sustainability challenges and social demands of our society in equal measure. One important aspect is the promotion of biological production cycles, which involve the introduction products or wastes from one production system to another, thereby optimizing the yield of the resources used. The Urban Plant Ecophysiology Group (Christian Ulrichs) investigated which food source resulted in the highest biomass gain of the fish species Nile tilapia to optimize resource utilization.

The GreenCityLabHuế project aims to strengthen the climate resilience of Huế, Vietnam, through nature-based solutions (NBS) for heat adaptation and air quality improvement. The project will create a multidisciplinary research space to develop and test NBS, focusing on green-blue infrastructure (GBI) and generate knowledge for stakeholders and decision-makers on NBS, resulting in a city-wide vision for sustainable urban development. In their Land-use change and nature-based solutions impact assessment the Landscape Ecology Group (Dagmar Haase) assesses the potential impacts of GBI interventions on ecosystem service supply and demand in Huế and estimate the benefits of GBI for air quality regulation and green space availability.

Not so long ago, beavers were threatened with extinction in Germany. The good news is that the German beaver population has grown considerably and is no longer considered an endangered species. The bad news is that we humans don't like it at all when someone else drastically and effectively changes the environment, especially if it is to our disadvantage. The Landscape Ecology Group (Dagmar Haase) has studied the competition in detail and analyzed where conflicts of interest arise between humans and beavers and discussed approaches that would enable a mutually acceptable coexistence.

Messenger RNA (mRNA) are molecules in cells that carry the genetic information from the DNA in the nucleus to specific cytes in the cytoplasm where their protein synthesis takes place. To this day it is not entirely clear how mRNA localization is regulated. One widely accepted mechanism is the regulation via localization sequences within the mRNA interacting RNA-binding proteins, however only few examples have been identified so far. In her nature cell biology Review, Marina Chekulaevasummarizes the existing knowledge from the literature to convey a holistic understanding of this fundamental process and potential underlying mechanisms.

The mood of the people around us can be contagious - both in a positive and negative sense. Cortisol, a hormone that is released in response to stress and low blood sugar levels, induces the increase of the glucose concentration in the blood, down-regulates the immune system and promotes the turnover of calories. Since the release of cortisol is connected to emotional experiences, one might think that it can therefore also be influenced by the emotional states in our environment, especially by those close to us. The Developmental and Educational Psychology Group (Denis Gerstorf) investigated if and how a person’s emotions influence the partner’s cortisol state and interestingly found that positive rather than negative emotions impact one’s partner on cortisol level.

Nowadays, we live in a world that is increasingly moving away from rural life towards urban life. The urban world we have created has a strong impact on our environment and also has a significant influence on our health and social life. But how will our cities look like in the future? It should be our concern to create a habitat in cities where both humans and diverse wildlife can coexist. The Landscape Ecology Group (Dagmar Haase) reviewed existing literature of wild mammals in urban areas to investigate how urban areas should be managed and shaped to achieve coexistence of humans and wild mammals. They identified shortcomings in the existing literature and defined five key elements for a research agenda. Check out their Basic and Applied Ecology Research paper.

Plasmonics is a field of study that explores the interaction between electromagnetic fields and free electrons in a metal. When light interacts with the surface of a metal at a specific frequency, it can excite collective oscillations of the metal's free electrons, known as plasmons. These plasmons can be confined to very small dimensions, much smaller than the wavelength of light, enabling the manipulation of light at the nanoscale. This characteristic has led to the application of surface plasmon resonance in a variety of areas such as surface-enhanced Raman scattering (SERS), metal-enhanced fluorescence (MEF), photocatalysis, optical trapping or heating. The Optical Nanospectroscopy Group (Janina Kneipp) has developed a method for a simple and low-cost preparation of functionalized nanoporous metal films decorated with rhodium nanoparticles, which can be exploited as plasmonic materials for enhanced UV Raman spectroscopy.

Stress is a natural human response that is triggered when we are under pressure or feel/are threatened. In our modern society stress appears to be a constant companion causing all kinds of stress-related disorders including depression and anxiety. This makes measures that promote our mental and physical well-being all the more important. The Psychological Research Methods Group (Manuel Völkle) compared the effectiveness of two online contemplative mental training programs and found that daily socio-emotional dyadic practices appear to represent a capable approach for stress reduction.

In his talk 'Nanodiamond quantum thermometers and their applications in biology' Masazumi Fujiwara introduced fluorescent nanodiamonds, which are stable and nontoxic fluorescent probes that are suited to chemical and biological analysis. Recently, they have been intensively studied for quantum applications because their electron-spin-dependent fluorescence can provide a sensitive measurement tool for nanoscale information of magnetic field and temperature. In his talk, Masazumi Fujiwara sproke about his group's effort on the implementation of this technology to temperature measurements in biological analysis (Fujiwara et al., 2020, Oshimi et al., 2022) with some recent results on their novel nanodiamonds (Oshimi et al., arXiv). Furthermore, he discussed potential applications of this technology.

The facial expression of emotions is important in regulating social interactions in everyday life. However, like any social signal, the perception of facial expressions, is influenced by contextual information such as body posture, the person’s physical environment, the voice or background knowledge about the person. The Social and Organizational Psychology Group (Ursula Hess) investigated whether expansive valence or rather specific emotion matches are responsible for providing context and how multiple sources of contextual information influence emotion recognition.

Bacteria make up just over half of our cells and live in or on our tissues and body fluids. Many of these tiny organisms perform essential tasks for us such as the fermentation of food, the protection against pathogens, the stimulation of our immune response as well as the production of vitamins. Representatives of the species Klebsiella oxytoca are an important part of the human microbiome, especially in the first years of our lives. Curiously enough, they are able to produce dangerous toxins, but still contribute significantly to the protection against colonization by exogenous microorganisms. The Molecular Microbiology Group (Marc Erhardt) investigated this phenomenon, which at first glance seems contradictory, in order to better understand the intermicrobial interactions. Have a look at their Nature Microbiology Article!

Malaria is a mosquito-transmitted life-threatening disease that is caused by the parasitic eukaryote plasmodium falciparum. Like most parasites, P. falciparum is dependent on the supply of nutrients from the host. One compound the organism is not able to sythesize itself is the lipid cholesterol. The Molecular Parasitology Group (Kai Matuschewski) investigated whether antimalarial drugs conjugated to cholesterol-analogous compounds show an antimalarial effect, which could provide a significantly improved drug efficiency.

Alzheimer’s disease (AD) is a neurodegenerative disorder that is associated with a progressing decline in cognitive function. In the majority of cases, symptoms like the deterioration of memory and thinking skills appear at an advanced age. The 'rich club' describes highly connected network hubs, whose  involvement in the development of AD is not clear at the moment. The Molecular Psychology Group (Sebastian Markett) was able to demonstrate first connections between AD and the rich club. You should definitely check our their Research Report published in Wiley!

Most people will probably have heard that the human-induced insect extinction is a major problem for the future of our planet as a habitat, as they perform fundamental functions such as pollinators or natural defense against pests. Insects, which belong to the Phylum of artropods are not the only creatures of this group that perform essential tasks. Even though creatures like spiders, scorpions, millipedes and centipedes are often disliked or even feared, they make important contributions to the biodiversity of ecosystems, breaking down decaying plant materials and control insect population sizes. The Urban Plant Ecophysiology Group (Christian Ulrichs) investigated the effect of different winter wheat cultivation systems on the biomass and abundance of arthopods.

City folk in particular often have an ambivalent relationship with trees. They beautify the cityscape, clean the air and provide us with oxygen, hold the soil together and protect it from erosion, the list goes on... On the other hand, the nasty trees rob us of our space to build buildings and roads and I'm pretty sure their chosen method of reproduction via pollen is simply to wipe out not just allergy sufferers but all of humanity. The Landscape Ecology Group (Dagmar Haase) addressed this topic in their Urban Ecosystems Article, which you should check out if you are interested in the future of humanity.

Malaria is a disease transmitted by mosquitoes that affects different kinds of vertebrates. Although the life cycle of the malaria-causing plasmodia - besides the mosquito - typically involves only one preferred type of vertebrate, there are regular infections of humans with non-human pathogens and vice versa.

We were happy to be able to support Frederick Saulich during his research stay the the Sattler Lab at the TUM in Munich and were excited to read his experience report. 

Plants like Arabidopsis thaliana can withstand a wide range of temperatures and can also tolerate large temperature fluctuations. This ability demands a high degree of flexibility from the plant, which is provided at the molecular level, among others, by phase separation. This phenomenon enables the formation of membrane-less compartments, which represent a dynamic and flexible alternative to organelles, as they can be rapidly modulated by changes in protein concentrations, metabolites, salt or temperature. The Molecular Genetics Group (Christian Schmitz-Linneweber) investigated the role of the protein CP29A in the adaptation to changing temperature conditions and found that the protein undergoes temperature-dependent phase separation thereby regulating the expression genes involved in adaptation to cold climate.

Complex collective behaviors of human, animal and even robotic collectives are the result of the interplay of individual dynamics and social interactions. To understand how individuals that are part of groups make use of social information e.g. during foraging together, and how this application of social information impacts the collective outcome through the behavior of single individuals, the Collective Information Processing Group (Pawel Romanczuk) developed a model that combines models of individual decision-making of foraging agents (evidence accumulation processes) with the movement models of these individuals in space.

The COVID-19 pandemic has impacted the mental and physical well-being of individuals across all age groups, but it's anticipated to have particularly prolonged and pronounced effects on younger populations. As loneliness has been linked to an increased risk of mental health problems such as depression, anxiety, and suicidal ideation as well as cardiovascular and cognitive issues, this should be considered a very serious matter. The Psychological Research Methods Group (Manuel Völkle) compared the effects of an app-based classic mindfulness training program and an innovative partner-based socio-emotional practice (Affect Dyad). Not surprisingly, the partner-based training program was more effective. You can find out more in their International Journal of Environmental Research and Public Health Article!

The C-terminal domain (CTD) of the RNA polymerase II serves as a flexible binding scaffold for numerous nuclear factors, which is controlled by its phosphorylation status. The CTD is important for the initiation of DNA transcription, mRNA capping and the association of the spliceosome with the transcript for mRNA splicing. Although phospho-specific antibodies are commonly used to detect CTD phosphorylation patterns, their recognition repertoire has barely been explored due to the challenging synthesis of long multiphosphorylated peptides. The Bioorganic Synthesis Group (Oliver Seitz) set out to develop a method that provides simple and reliable access to multiphosphorylated CTD peptides of up to 12 heptad repeats (84 amino acids) in length.

Schizophrenia is a mental disorder that is predominantly characterized by recurring psychotic episodes and can be associated with other symptoms such as hallucinations (e.g. hearing voices), delusions (e.g. paranoia), disorganized thinking or social withdrawal. Many people associate the label 'schizophrenia' with negative and often false beliefs and consequently the concerned individuals often face a negative perception and treatment. The Social and Organizational Psychology Group (Ursula Hess) investigated how the label 'schizophrenia' affects liking, interpersonal closeness, and emotional mimicry, to assess what this tenacious stigma is based on.

The COVID-19 pandemic caused until then unprecedented changes in people's lifestyle, work and social interactions. Social distancing and the closing of gathering and interaction centers such as parks, cafes, educational institutions etc., entailed certain social, mental and physical health circumstances. One predominant factor was unintentional changes in body weight, which have been reported for younger and middle-aged adults. As the affect on older adults was hardly considered, the Developmental and Educational Psychology Group (Denis Gerstorf) investigated this particular age group in the course of the pandemic.

Sows spend most of their time lying down, and their lying behavior and, in return also, their activity level appear to be indicators of their welfare, as they reflect their ability to meet their physical and behavioral needs for rest or movement, which is especially important during parturition and lactation. The Animal Husbandry and Ethology Group (Lorenz Gygax and Edna Hillmann) investigated lying behavior of crated and free farrowing sows to compare how the distinct housing systems allow them to fulfill their needs for rest or movement and to evaluate the accuracy of accelerometer-based sow lying behavior classification.

Fluorescence molecular rotors (FMRs) are a group of fluorescent molecules that undergo an intramolecular twisting motion, which non-radiatively depletes the excited state. As a result, environments that prevent this twisting motion, produce enhanced fluorescence. In the past, these dyes have been used mainly to measure nanoviscosity or interactions of FMR-labelled ligands with proteins and nucleic acids. The Bioorganic Synthesis Group (Oliver Seitz) explored covalent labelling of cell surface sialic acids with the FMRs and established the application of FMR dyes to detect interactions with glycans, expanding the use of FMRs.

Semiconducting quantum dots (QDs) hold significant potential for scalable quantum information processing as the localized electrons and spins can be used as qubits, a two-state quantum-mechanical system. In coupled QDs, the electrons can be entangled, which means that the quantum state of one particle cannot be described independently of the state of the other. The simplest example of two qubits’ quantum entanglement are the Bell sates, a form of entangled and normalized basis vectors. The Statistical Physics and Nonlinear Dynamics Group (Igor Sokolov) investigated the stability of different two-qubit entangled Bell states in coupled QDs in the presence of fluctuations.

Summer in Berlin feels so much hotter and more suffocating than it does on the countryside, especially during the night, when temperatures just won't drop. To counteract the urban heat island effect, particularly as temperatures will only rise in the upcoming years, the expansion of green spaces (GS), which have a cooling effect, is a prerequisite for for living in cities in the future. The Landscape Ecology Group (Dagmar Haase) investigated, the relationship between GS and land surface temperature using the Chinese megacity Guangzhou as an example and found that a combination of increasing the area and optimizing the spatial distribution of green spaces results in the best cooling effects.

Dormancy is a temporary and reversible slowdown or suspension of an organism's regular physical functions. This state is a ubiquitous trait in microbial communities, but can also be found in complex organisms including animals and plants. The Interdisciplinary Mathematics Group (Maite Wilke Berenguer) investigated the impact of dormancy on evolutionary branching and found that this seemingly passive state has a significant influence on the development of populations with new traits and, as a consequence, diversity.

Non-coding RNAs (ncRNAs) form a diverse group of transcripts that, by definition, are not translated to produce proteins. For this reason, they were first classified as non-functional by-products or mis-products of transcription (or junk RNA). However, it became clear with time that ncRNAs act as important regulators that influence various biological functions in different cell types and tissues as they comprise transfer RNAs (tRNAs) and ribosomal RNAs (rRNAs), as well as small RNAs such as microRNAs, siRNAs, piRNAs, snoRNAs, snRNAs, and also long ncRNAs. 
In their Journal of Neurochemistry Review Marina Mikhaylova, together with Mason Musgrove and Timothy Bredy from the Queensland Brain Institute in Australia, portrayed groups of ncRNAs enriched in the brain that play a crucial role in the functional aspects of both learning and memory, as well as adaptive immunity, and reflect on how they might facilitate the exchange between these two evolutionarily old biological systems.
