Article Abstract
The origin of cellular life can be described in terms of the transition from inorganic matter to the emergence of cooperative assemblies of organic matter: DNA and proteins, capable of replication and metabolism. Directionality theory is a mathematical theory of the collective behaviour of networks of organic matter: activated macromolecules, cells and higher organisms. Evolutionary entropy, a generalization of the thermodynamic entropy of Boltzmann, is a statistical measure of the cooperativity of the biotic components. The cornerstone of Directionality theory is the evolutionary entropy in systems driven by a stable energy source, and in systems subject to a fluctuating energy source. This article invokes the Entropic Principle of Evolution-an extension to biological systems of the Second Law of Thermodynamics-to provide an adaptive rationale for the following sequence of transformations that define the emergence of cellular life: (i) the self-assembly of activated macromolecules from inorganic matter; (ii) the emergence of an RNA world, defined by RNA molecules with catalytic and replicative properties; and (iii) the origin of cellular life, the integration of the three carbon-based polymers-DNA, proteins and lipids, to generate a metabolic and replicative unit.

Psychosocial predictors of short-term glucose among people with diabetes: A narrative review.

Type 1 and type 2 diabetes are metabolic disorders that require one to manage one's blood glucose levels on a daily basis through a series of behaviorally complex tasks. Research shows that psychosocial factors, including mood, stress, and social relationships, have a significant influence on one's ability to maintain these disease management routines and achieve healthy blood glucose levels. However, researchers have typically approached these questions from a between-person perspective.

Laureate Institute for Brain Research, Tulsa, OK, USA.
With the advent of human neuroimaging, researchers were drawn to the idea that by better understanding the human brain, more effective mental health interventions could be developed. It has been more than 20 years since the first functional magnetic resonance imaging (fMRI) studies were conducted to examine changes in brain activation with anxiety-related treatments and more than 60 studies have since been published in this vein. For the current review, we conduct a systematic review of this literature, focusing on adult studies using task-based fMRI to measure brain activation changes with pharmacologic or psychotherapy interventions for phobia, social anxiety disorder, panic disorder, generalized anxiety disorder, posttraumatic stress disorder, and obsessive-compulsive disorder.

Ion mobility spectrometry (IMS) (also including IMS-IMS measurements) as well as DFT calculations have been used to study isomer distributions and isomer interconversion in a range of electrospray-generated lanthanide chloride cluster anions, LnCl (where = 1-6, and Ln corresponds to the 15 lanthanide elements (except for radioactive Pm)). Where measurement and structural rearrangement timescales allow, we obtain almost quantitative agreement between experiment and theory thus confirming isomer predictions and reproducing isomer intensity ratios. LnCl structures reflect strong ionic bonding with limited directionality.

Article Synopsis
- Young infants initially can differentiate sounds from various languages, supporting the perceptual narrowing hypothesis, which suggests they become less sensitive to non-native phonemes as they grow.
- This study investigated how 4-6 month-old Korean and Japanese infants respond to specific Thai phoneme contrasts, specifically looking at their ability to discriminate between different stop sounds based on voice onset time (VOT).
- Findings revealed that Korean infants were sensitive to the pre-voiced vs. voiceless contrast, while Japanese infants were better at distinguishing the voiceless vs. voiceless aspirated sounds, highlighting significant differences in language input's impact on infants' phoneme discrimination abilities.

Valence bond theory (VB) was used to determine the extent and driving forces for covalent vs. dative bonding in 10-valence-electron diatomic molecules N, CO, NO, CN, P, SiS, PS, and SiP. VBSCF calculations were performed at the CCSD(T)/cc-pVDZ optimized geometries.
