From Silke Sachse:
"I would like to draw your attention to the announcement of a professorship (W3 level) in Behavioral Physiology at the University of Würzburg. Please help to spread the word to suitable candidates."
Application deadline is June 22nd, 2025.

"“For me, the takeaway is we know very little—even the very basic of how they find a site,” Parzer says. “Then there’s a lot of species variation. Why are some puddling a lot? Why are some not at all? We have some species where females also puddle—why is that? And then we noticed there’s a big gap. A whole continent is essentially missing—Africa—so there clearly needs to be something done in that area as well.”"

Why We Do What We Do by Helena Boschi, 2020
Understanding Our Brain to Get the Best Out of Ourselves and Others
Why We Do What We Do combines scientific research with concrete examples and illustrative stories to clarify the complex mechanisms of the human brain. It offers valuable insights into how our brain works every day, at home and at work, and provides practical ideas and tips to help us lead happy, healthy and productive lives.

As the election gets closer, #extremism and #conflict is happening at polling booths with unruly candidate, party members and constituants.
“A barrage of #complaints about #threatening and #aggressive #behaviour at polling booths has fuelled tension in Australia’s most hotly #contested #electorates and prompted the #ElectoralCommission to warn #candidates in marginal seats that such behaviour would discourage #voters”

Behavioral Neurobiology of PTSD by Eric Vermetten et al,
This volume focuses on the behavioral neuroscience that supports our understanding of the neurobiology of trauma risk and response. The collection of articles focuses on both preclinical and clinical reviews of (1) state-of-the-art knowledge of mechanisms of posttraumatic stress disorder (PTSD) and co-occurring disorders.

bioRxiv · An optimized appetitive visual short-term memory paradigm in DrosophilaThe ability to generate and recall memory is a behavior that is evolutionarily conserved across the animal kingdom from humans to jellyfish. Memory not only allows previous experiences to inform future decision making, but it also amasses information essential to life, such as memory of quality food sources, shelter, and predator-related associations. Associative memory forms a relationship between two or more distinct and initially unrelated stimuli and can be defined by its temporal characteristics, such as shortand long-term duration, as well as the memory being appetitive or aversive, generating approach or avoidance behavior, respectively. Since its introduction as a memory model in the 1970s, the fruit fly, Drosophila melanogaster, has emerged as a powerful tool for the investigation of memory-related processes. While a variety of memory paradigms have been used extensively in Drosophila, such as appetitive and aversive olfactory memory, the use of appetitive visual memory remains infrequent. A previous study introduced a visual shortterm memory (STM) paradigm that could be used for the study of both appetitive and aversive visual memory in Drosophila. However, this protocol required 50+ flies per condition, with three conditions per experiment, and 15 or more replications were frequently used to assess memory. As a result, this paradigm requires substantial numbers of flies, time, and is impractical for large genetic screens. Here, building upon this previous work, we describe an optimized appetite visual STM paradigm in freely moving Drosophila. Using recently published data on sexual dimorphism, innate color preferences, and borrowing practices from related appetitive assays, we have established an approach that minimizes confounding factors, such as sexually dimorphic starvation survival and sucrose preference, as well as pre-training color preference variation between groups. In doing so, we present an appetitive visual STM paradigm requiring substantially fewer replicates and numbers of flies to produce significant learning.

"miR-124 acts during Drosophila development to determine the phase of adult circadian behavior"

bioRxiv · miR-124 acts during Drosophila development to determine the phase of adult circadian behaviorCircadian behaviors need to be properly phased with the day/night cycle to be beneficial. We previously showed that the microRNA miR-124 regulates circadian behavior phase in Drosophila . Here, we report that miR-124 expression during larval development is required for proper phasing of both morning and evening peaks of activity in adults. Loss of miR-124 results in significant miswiring within the circadian neural network and severely alters neural activity rhythms in the ventral Lateral Neurons (s-LNvs) and the posterior Dorsal Neurons 1 (DN1ps), which control the timing of morning and evening activity. Silencing the s-LNvs in miR-124 mutant flies restores the phase of evening activity, while activating the DN1ps rescues the phases of both morning and evening activities. Our findings thus reveal the pivotal role of miR-124 in sculpting the circadian neural network during development and its long-lasting impact on circuit activity and adult circadian behavior.
