Review on Thermal Stimulation in Deep Geothermal Reservoirs: Thermo-Mechanical Mechanisms and Fracture Evolution

Kaituo Li, Lin Zhu, Fei Xiong et al. · 2026 · Processes

Enhanced geothermal systems (EGS) are a key technology for developing deep geothermal resources, yet they face significant challenges in constructing efficient thermal reservoirs within high-stress, high-strength, and low-permeability crystalline rock formations. Traditional hydraulic fracturing (HF) techniques encounter deep challenges in these environments, including excessively high fracturing pressures, limited fracture network patterns, and the risk of induced seismicity. This paper reviews the multi-scale thermal-mechanical mechanisms, fracture evolution patterns, and control strategies

Language models transmit behavioural traits through hidden signals in data

Alex Cloud, Minh Le, James Chua et al. · 2026 · Nature

. Here we show that distillation can lead to subliminal learning-the transmission of behavioural traits through semantically unrelated data. In our main experiments, a 'teacher' model with some trait T (such as disproportionately generating responses favouring owls or showing broad misaligned behaviour) generates datasets consisting solely of number sequences. Remarkably, a 'student' model trained on these data learns T, even when references to T are rigorously removed. More realistically, we observe the same effect when the teacher generates math reasoning traces or code. The effect occurs on

Curcumin Between Pleiotropic Potential and Translational Constraints

Alessandro Magini, Alessandro Datti · 2026 · International Journal of Molecular Sciences

Curcumin is widely recognized for its anti-inflammatory and antioxidant properties; however, this conventional framing obscures a broader, complex, and mechanistically diverse pharmacology. Here, we advance a refined perspective that situates curcumin within a hierarchical and multilayered architecture shaped by the dynamic interplay of intrinsic chemical reactivity, metabolic transformation and exposure, and microbial modulation. From this standpoint, curcumin functions as a network-level modulator, producing context-dependent outcomes rather than uniform or linear responses. Consequently, it

Central and Peripheral Sensitization in Temporomandibular Disorders: Proposed Mechanisms of Botulinum Toxin Therapy

Basit Ali Chaudhry, Christopher Louis Robinson, Edoardo Caronna et al. · 2026 · Toxins

Temporomandibular disorders (TMDs) are common musculoskeletal chronic orofacial pain conditions involving peripheral and central sensitization within trigeminal nociceptive pathways, manifesting as mechanical allodynia and functional impairment. Botulinum toxin type A (BoNT-A) has been explored as a treatment targeting both muscle hyperactivity and nociceptive modulation. Preclinical and clinical evidence demonstrate that BoNT-A reduces peripheral neurotransmitter release, neurogenic inflammation, and central neuronal excitability, leading to attenuation of mechanical allodynia in TMD models a

Limited evidence for reduced learning rate adaptation in anxious-depression, before or after treatment

Steph F Suddell, Lili Zhang, Chi Tak Lee et al. · 2026 · Psychological Medicine

Abstract Background Prior research shows that humans adjust their learning rate based on environmental volatility. This adaptation has been shown to be reduced in individuals with high levels of anxious-depression, but past studies have been cross-sectional, making it unclear whether this adaptation is trait-like or responsive to treatment. There are also questions about the basic replicability of this effect with recent studies failing to find robust associations. Method In the Precision in Psychiatry study, we examined changes in learning rate adaptation in a points-loss task, following four

Socioeconomic status and subdivisions of the amygdala and hippocampus in children and adolescents

Jamie Lars Hanson, Dorthea J Adkins, Brendon M. Nacewicz et al. · 2026 · Brain and Environment

Socioeconomic status (SES) in childhood can impact behavioral and brain development. Past work has consistently focused on the amygdala and hippocampus, two brain areas critical for emotion and behavioral responding. While there are SES differences in amygdala and hippocampal volumes, there are many unanswered questions in this domain connected to neurobiological specificity, and for whom these effects may be more pronounced. We may be able to investigate some anatomical subdivisions of these brain areas, as well as if relations with SES vary by participant age and sex. No work to date has how

Insights into Photo Degradation and Stabilization Strategies of Antibody–Drug Conjugates with Camptothecin Payloads

Shukun Luo, Joshua Bulos, Ricky Uroza et al. · 2025 · Pharmaceutics

Background: Photostability assessment is a critical component in the development of drug products, particularly for antibody–drug conjugates (ADCs) containing light-sensitive small molecules such as camptothecin (CPT) and its derivatives. ADCs conjugated with CPT derivative payloads often require extensive formulation and drug product development to ensure product stability due to their unique light-induced degradation pathways. In this study, we assessed the photostability of two ADC molecules with a CPT derivative payload (deruxtecan, DXd). Methods: Following light exposure, the stability of

Comparison of water models for structure prediction

Bálint Soczó, Ildikó Pethes · 2025 · Journal of Molecular Liquids

Describing the interactions of water molecules is one of the most common, yet critical, tasks in molecular dynamics simulations . Because of its unique properties, hundreds of attempts have been made to construct an ideal interaction potential model for water. In various studies, the models have been evaluated based on their ability to reproduce different properties of water. This work focuses on the atomic-scale structure in the liquid phase of water. Forty-four classical water potential models are compared to identify those that can accurately describe the structure in alignment with experim

Fluorescence-based mapping of condensate dielectric permittivity uncovers hydrophobicity-driven membrane interactions

Elias Sabri, Agustín Mangiarotti, Rumiana Dimova · 2026 · Nature Communications

Biomolecular condensates, essential for cellular organization, possess mesoscale properties largely governed by hydrophobicity, influencing molecule partitioning and material characteristics like viscosity, surface tension, and hydration. While hydrophobicity's role is increasingly recognized, its impact on membrane-condensate interactions remains unexplored. Here, we combine hyperspectral imaging of an environment-sensitive dye and phasor analysis, to quantitatively map the local dielectric permittivity of both condensates and their environment with pixel resolution. This robust method senses

Improving medication adherence in type 2 diabetes: strategies for better clinical and economic outcomes

Patrick Highton, Mark P. Funnell, Pankaj Gupta et al. · 2025 · Diabetologia

Abstract Medication adherence is critical for optimal glycaemic management and the prevention of complications in type 2 diabetes mellitus. Despite its importance, non-adherence remains a prevalent issue, with global estimates suggesting that approximately 38% of people with type 2 diabetes do not take their medications as prescribed, although estimates vary widely due to a range of patient-related, socioeconomic, condition-related (e.g. chronicity, severity of comorbidities) and healthcare system factors. This review synthesises the current evidence on the prevalence of non-adherence in type

A journey of seeking pressure and forces in the nucleon

Xiangdong Ji, Yang Chen · 2026 · Nuclear Physics B

Momentum current density (MCD) $T^{ij}$ is a general physics concept describing the momentum conservation through momentum flow generated from both the kinetic motion of particles and the interacting forces among them. It has been suggested by M. Polyakov et al. that the MCD in the nucleon, characterized by the form factor $C/D$ of the QCD energy-momentum tensor, can be interpreted as the pressure and shear forces between adjacent parts of the system because the nucleon interior approximates a continuous medium. While intuitively appealing, we find that the interpretation is hard to justify fr

Gut‒heart axis: emerging therapies targeting trimethylamine N-oxide production

Efrain Ricardo Torres, Jennifer Wilcox, W. H. Wilson Tang · 2025 · Gut Microbes

Trimethylamine N-oxide (TMAO) has garnered considerable attention because of its role in the pathophysiology and pathogenesis of various disorders, particularly heart and kidney disease. Gut microbes produce trimethylamine (TMA) moieties from common dietary precursors, such as choline or carnitine, which are subsequently metabolized by the liver into TMAO. Circulating TMAO then exerts various effects, influencing dyslipidemia, metabolic syndrome, endothelial dysfunction, and inflammation, as well as other detrimental processes. Many existing medications have been shown to decrease TMAO levels

Altitude hypoxia and hypoxemia: pathogenesis and management

Chunmei Cai, Guohua Ni, Lei Chen et al. · 2026 · Signal Transduction and Targeted Therapy

At high altitudes, which typically exceed 2500 m, approximately 80 million people reside permanently, with over a million visitors annually. The primary effect of high altitude is hypobaric hypoxia, which leads to decreased oxygen availability and a cascade of physiological responses. However, inadequate or excessive responses can lead to malacclimatization, resulting in hypoxemia and various high-altitude illnesses, including acute mountain sickness (AMS), high-altitude cerebral edema (HACE), high-altitude pulmonary edema (HAPE), chronic mountain sickness (CMS), and high-altitude pulmonary hy
