The neural basis of the insight memory advantage.

Trends Cogn Sci

January 2025

Department of Psychology, Humboldt University Berlin, Berlin, Germany; Center for Cognitive Neuroscience, Duke University, Durham, NC 27708, USA.

Creative problem solving and memory are inherently intertwined: memory accesses existing knowledge while creativity enhances it. Recent studies show that insights often accompanying creative solutions enhance long-term memory. This insight memory advantage (IMA) is explained by the 'insight as prediction error (PE)' hypothesis which states that insights arise from PEs updating predictive solution models and thereby enhancing memory.

Revealing microRNA regulation in single cells.

Trends Genet

January 2025

Institute for Computational Genomic Medicine, Goethe University Frankfurt, Frankfurt, Germany; German Centre for Cardiovascular Research (DZHK), Partner Site Rhine-Main, Frankfurt, Germany. Electronic address:

MicroRNAs (miRNAs) are key regulators of gene expression and control cellular functions in physiological and pathophysiological states. miRNAs play important roles in disease, stress, and development, and are now being investigated for therapeutic approaches. Alternative processing of miRNAs during biogenesis results in the generation of miRNA isoforms (isomiRs) which further diversify miRNA gene regulation.

Acetate is a biological anion with many applications in the chemical and food industries. In addition to being a common microbial fermentative end-product, acetate can be produced by photosynthetic cyanobacteria from CO using solar energy. Using wild-type cells of the unicellular model cyanobacterium Synechocystis PCC 6803 only low levels of acetate are observed outside the cells.

Integrative deep immune profiling of the elderly reveals systems-level signatures of aging, sex, smoking, and clinical traits.

January 2025

Institute of Immunology, Hannover Medical School, Hannover, Germany; Cluster of Excellence RESIST (EXC 2155), Hannover Medical School, Hannover, Germany; German Centre for Infection Research, Partner Site Hannover-Braunschweig, Hannover, Germany. Electronic address:

Background: Aging increases disease susceptibility and reduces vaccine responsiveness, highlighting the need to better understand the aging immune system and its clinical associations. Studying the human immune system, however, remains challenging due to its complexity and significant inter-individual variability.

Methods: We conducted an immune profiling study of 550 elderly participants (≥60 years) and 100 young controls (20-40 years) from the RESIST Senior Individuals (SI) cohort.

Lung function-associated exposome profile in the era of climate change: Pooled analysis of 8 population-based European cohorts within the EXPANSE project.

Environ Int

January 2025

Swiss Tropical and Public Health Institute, Allschwil, Switzerland; Department of Public Health, University of Basel, Basel, Switzerland. Electronic address:

Background: The independent and interrelated long-term effects of the exposome such as air pollution, greenness, and ambient temperature on lung function are not well understood, yet relevant in the light of climate change.

Methods: Pre-bronchodilation FEV1 from five mature birth cohorts (N = 4724) and three adult cohorts (N = 6052) from five European countries were used to assess cross-sectional associations with air pollution, greenness, and ambient temperature, assigned to their residential address. All two-way interactions and square terms were a priori included in building the final elastic net regression model.

Department of Health Economics and Health Services Research, University Medical Center Hamburg-Eppendorf, Hamburg Center for Health Economics, Hamburg, Germany.

Objectives: To examine how homeboundness is associated with psychosocial outcomes in terms of life satisfaction, positive affect, negative affect and loneliness among middle-aged and older adults.

Methods: Longitudinal data were taken from the nationally representative sample German Ageing Survey (wave 1 to wave 4; n = 18,491 observations). This study included community-dwelling individuals aged 40 years and over in Germany.

Two event-related brain potential (ERP) components, the frontocentral feedback-related negativity (FRN) and the posterior P300, are key in feedback processing. The FRN typically exhibits greater amplitude in response to negative and unexpected outcomes, whereas the P300 is generally more pronounced for positive outcomes. In an influential ERP study, Hajcak et al.

Objectives: Caffeine, a known neurostimulant and adenosine antagonist, affects brain physiology by decreasing cerebral blood flow. It interacts with adenosine receptors to induce vasoconstriction, potentially disrupting brain homeostasis. However, the impact of caffeine on blood-brain barrier (BBB) permeability to water remains underexplored.

January 2025

Department of General, Visceral and Thoracic Surgery, University Medical Center Hamburg- Eppendorf, Martinistraße 52, D-20246, Hamburg, Germany.

Purpose Of Review: Neuroendocrine tumours (NET) are rare entities arising from hormone producing cells in the gastroentero-pancreatic (GEP) tract. Surgery is the most common treatment of GEP-NETs.

Recent Findings: Improvements in surgical techniques allow for more locally advanced and metastasised GEP-NETs to be resected.
