Fostering programming skill and critical thinking through AI-assisted PBL integration

Christian Basil Omeh, Musa Adekunle Ayanwale, Lindelani Mnguni et al. · 2025 · Journal of New Approaches in Educational Research

Abstract Despite the increasing emphasis on computational literacy in higher education, we observed that many undergraduate students particularly in developing contexts struggle to master fundamental programming skills and develop critical thinking. Conventional instructional approaches often lack interactivity and personalized scaffolding, which are essential for teaching abstract programming concepts. In response to this challenge, we examined the effect of artificial intelligence (AI)-assisted problem-based learning (PBL) on students’ programming skills, critical thinking, and problem-solvi

Melanoma: Pathogenesis and Targeted Therapy

Yang Fu, Jie Liu, Zeming Mo et al. · 2026 · MedComm

ABSTRACT Melanoma is the most aggressive skin malignant tumor, typically exhibiting a high mutation burden and potentially harboring mutations in NRAS, BRAF, or NF1. To enhance survival rates, these driver alterations can achieve significant antitumor activity through targeted therapy. In the past decade, BRAF inhibitors combined with MEK inhibitors significantly improved the prognosis of BRAF mutation melanoma. Nevertheless, researchers have attempted various strategies to block the NRAS signaling pathway, NRAS mutation in melanoma is still considered to be untargetable. In recent years, MEK

Digital Twins for Cows and Chickens: From Hype Cycles to Hard Evidence in Precision Livestock Farming

Suresh Raja Neethirajan · 2026 · Agriculture

Digital twin technology is widely promoted as a transformative step for precision live-stock farming, yet no fully realized, engineering-grade digital twins are deployed in commercial dairy or poultry systems today. Existing platforms are better described as near-digital-twin systems with partial sensing and modelling, digital-twin-inspired prototypes, simulation frameworks or decision-support tools that are often labelled as twins despite lacking continuous synchronization and closed-loop control. This distinction matters because the empirical foundation supporting many claims remains limited

Connecting Environment, Star Formation History, and Morphology of Massive Quiescent Galaxies at 3 < z < 4 with JWST

Lalitwadee Kawinwanichakij, Karl Glazebrook, Themiya Nanayakkara et al. · 2026 · The Astrophysical Journal

Abstract We present the morphological properties of 17 spectroscopically confirmed massive quiescent galaxies ( 10.2 < log ( M * / M ⊙ ) < 11.2 ) at 3.0 < z < 4.3, observed with JWST/NIRSpec and NIRCam. Using Sérsic profile fits to F277W and F444W imaging, we derive the size–mass relation and find typical sizes of ∼0.6–0.8 kpc at M * = 5 × 10 10 M ⊙ , consistent with ∼7× growth from z ∼ 4 to the present, including ∼2× by z ∼ 2. We find tentative evidence that formation history and morphology jointly influence galaxy sizes: late-forming bulge-dominated galaxies appear more compact by ∼0.2–0.3 d

GLP‐1 at the Metabolic–Cognitive Interface: Reward, Affect, and Memory

Shangkai Gao, Léa Décarie-Spain, Cindy Gu et al. · 2026 · Comprehensive physiology

Glucagon-like peptide-1 (GLP-1) is a nutrient-responsive hormone classically associated with glucose homeostasis and food intake control, yet its receptor is broadly expressed throughout the central nervous system (CNS) in circuits governing complex cognitive processes. Here, we synthesize emerging evidence from preclinical models and human studies demonstrating that GLP-1 receptor (GLP-1R) signaling modulates multiple cognitive domains, including reward and motivational processes relevant to obesity and substance use disorder, affective-related behaviors, and learning and memory.

Lethal plague outbreaks in Lake Baikal hunter-gatherers 5,500 years ago

Ruairidh Macleod, Frederik Valeur Seersholm, Bianca De Sanctis et al. · 2026 · Nature

Abstract Plague is among the most devastating diseases in human history 1 . However, early strains of the plague-causing bacterium Yersinia pestis lacked virulence factors that are required for the bubonic form until around 3,800 years ago 2,3 . Consequently, the morbidity and mortality of early plague strains remain unclear. Here we describe early plague strains that are associated with two phases of outbreaks among mid-Holocene hunter-gatherers near Lake Baikal in southeast Siberia, beginning from about 5,500 years ago. These outbreaks occur across four hunter-gatherer cemeteries, with a 39%

Spurious effects in random-intercept cross-lagged panel models: Results from simulations and reanalyses of data on self-esteem and problematic eating behaviors used by Beckers et al. (2023)

Kimmo Sorjonen, Gustav Nilsonne, Ata Ghaderi et al. · 2026 · PLoS ONE

The random-intercept cross-lagged panel model (RI-CLPM) is an extension of the traditional cross-lagged panel model. The RI-CPLM specifically addresses prospective effects within individuals. In the present simulations, we found that the RI-CLPM is susceptible to spurious findings when observed scores on the two variables are affected by common auto-correlated state factors. In reanalyses of empirical data, we found contradictory decreasing, increasing, and null prospective effects between within-individual levels of self-esteem and problematic eating behaviors among Dutch teenagers (N = 1856)

Unraveling Chronic Pain: From Mechanisms and Risks to Diagnosis and Treatment

Xiaofeng Dai, Chongxiang Wang, Ping Jiang et al. · 2026 · MedComm

Chronic pain is a globally prevalent and complex condition, encompassing three primary subtypes, that is, nociceptive, neuropathic, and nociplastic, each with distinct biopsychosocial mechanisms. Chronic pain was historically viewed as a monolithic symptom and managed with opioid-centric models, causing widespread therapeutic failure. While recognition of its heterogeneity has driven a paradigm shift toward precision medicine, tailoring multimodal strategies to the dominant pain mechanism, critical challenges persist. These include difficulty in identifying treatable root causes, limited long-
