IMPACT OF PYROLYSIS TEMPERATURE ON PINE CONE ACTIVATED CARBON FOR CATALYST SUPORT MATERIAL FUEL CELL
The high cost and limited durability of platinum-based catalysts remain major challenges for the large-scale commercialization of fuel cell. Therefore, alternative and more affordable catalyst support materials are needed.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

UPTAKE AND RETENTION OF FIXED CARBON IN ADULT MICE [PDF]
1. Mice were continuously exposed to air containing C14O2. The specific radioactivities of urea carbon, total fecal carbon, and numerous components of tissue carbon were compared as a function of the duration of exposure with the radioactivity of the air CO2. 2.

Reconstructing enzyme evolution by protein engineering
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Liver organoids: modelling complexity in homeostasis and disease
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Epigenetic reprogramming of lineage switching in cancer
Cancer cells rarely commit to a single identity. Epigenetic mechanisms and tumor microenvironment cues push epithelial cells toward flexible, hybrid states that can shift into mesenchymal, neuroendocrine, or stem‐like fates, driving metastasis, drug resistance, and tumor heterogeneity. Targeting the epigenetic regulators behind these transitions, using
