New partial skeleton of Homo habilis from the upper Burgi Member, Koobi Fora Formation, Ileret, Kenya

open access: yesThe Anatomical Record, EarlyView.
Abstract KNM‐ER 64061 is a partial skeleton from the upper Burgi Member of the Koobi Fora Formation (2.02–2.06 Ma) associated taphonomically and geochemically with a nearly complete mandibular dentition (KNM‐ER 64060) attributed to Homo habilis.

Synthesis, Characterization, Biological Properties, and Sensor Applications of Novel Thiosemicarbazone Derivatives

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT In this study, novel thiosemicarbazone derivative molecules (5a–j) were synthesized. The characterization of the synthesized molecules was carried out using 1H–, 13C–NMR, FT–IR, and Q–TOF spectroscopic techniques. Then, the inhibitory effect of these compounds was examined for human carbonic anhydrase I and II (hCA I, and II) and ...

Binder‐Free Self‐Standing Hard Carbon Electrodes Graphite‐Coated by PE‐CVD to Boost the Efficiency of Na‐Ion Batteries

open access: yesBatteries &Supercaps, EarlyView.
Binder‐free, self‐standing hard carbon electrodes (SSEs) are designed and utilized as anodes in Na‐ion batteries, demonstrating a high reversible capacity of 320 mAh g−1. Coating the SSEs with nanographite via plasma‐enhanced chemical vapor deposition limits the formation of solid electrolyte interphase, thereby improving the iCE to 92.5%.

Elevated Hemoglobin Levels and Risk of ST‐Segment Elevation Myocardial Infarction in High‐Altitude Acute Coronary Syndrome: A Retrospective Analysis

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background High‐altitude populations typically exhibit elevated hemoglobin (Hb) levels due to chronic hypoxic exposure; however, the impact of this elevation on the risk of ST‐segment elevation myocardial infarction (STEMI) remains unclear. Existing evidence is primarily derived from low‐altitude populations and cannot be directly extrapolated

Highly Potent Fluorogenic Ligands for Triplex DNA: 5‐Substituted 2‐(Naphthalen‐2‐yl)‐4H‐Chromen‐4‐Ones

open access: yesChemistry – A European Journal, EarlyView.
5‐Substituted 2‐(naphthalen‐2‐yl)‐4H‐chromen‐4‐ones are reported as a novel class of highly potent and selective triplex DNA ligands. These ligands induce triplex formation at submicromolar concentrations and inhibit enzymatic activity via ligand‐mediated triplex formation.

Automated Creak Identifies Laryngeal Dystonia During Conversational Speech

open access: yesThe Laryngoscope, EarlyView.
This study evaluated whether automated creak distinguished speakers with adductor laryngeal dystonia (AdLD), muscle tension dysphonia (MTD), and those without voice disorders during conversational speech. Automated creak estimates were able to differentiate speakers with AdLD from MTD and controls with similar performance across different types of ...

CO2 Fluxes and Soil Responses to Straw and Herbicide in Peanut

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Peanut cultivation plays an important agronomic role in Brazil, especially in rotation with sugarcane, promoting biological nitrogen fixation and improving soil quality. This study aimed to test the hypothesis that the combined use of sugarcane mulch, peanut cultivation, and herbicide application would affect soil CO₂ fluxes, soil chemical ...

Polymerized Pro‐Estrogen Microneedles via Two Photon Polymerization

open access: yesMacromolecular Rapid Communications, EarlyView.
Acrylic pro‐drugs of 17β‐estradiol were subjected to spatially controlled two‐photon polymerization to create bespoke microneedle geometries with potential biomedical applications for long‐term transdermal hormone delivery. ABSTRACT Two‐photon polymerization (TPP) is a powerful technique to create microscale structures with high precision, offering ...

Dose‐Dependent Effects of Biochar on Soil Revealed by Fast Field‐Cycling (FFC) NMR: From Molecular Water Dynamics to Soil Functionality

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Dose–response of biochar in a clay soil: fifteen mixtures (fBC 0–1) reveal nonlinear thresholds (pH/EC) and sharp WHC gains near fBC ≈ 0.3–0.5. Coupled FT‐IR and FFC‐NMR (0.01–10 MHz; ModelFree τc distributions) link water dynamics to soil functionality.

Artichoke Bracts and Stems Residues as Active Filler for Poly(Butylene Succinate‐Co‐Adipate) (PBSA) Composites: From Agro‐Waste to a New Sustainable Material

open access: yesPolymer Composites, EarlyView.
PBSA‐based biocomposites made from artichoke bract and stem powders have been characterised and formulated for agricultural and food applications, such as active mulching films. ABSTRACT In the context of a growing bioeconomy and the drive for sustainable materials, new biocomposites were formulated by incorporating poly(butylene succinate‐co‐adipate) (
