Decoding the Hot-Mitochondrion Paradox
Peyman Fahimi, Michael Lynch, Cherif F. Matta
In a 2018 paper and a subsequent article published in 2023, researchers reported that mitochondria maintain temperatures 10oC-15oC higher than the surrounding cytoplasm-a finding t…
Benchmarking Astrochemistry Paradigms: Relative Absence of C6H5CN+ in the Diffuse ISM
Daniel Majaess, Cercis Morera-Boado, Tina A. Harriott +4
The detectability of C6H5CN+ (benzonitrile cation) in the diffuse ISM is re-evaluated. A holistic evidentiary framework suggests C6H5CN+ is relatively absent in the diffuse ISM owi…
On the Anticipation of Lunar Travel in the Early 20th Century: A Pedagogical Exercise
Tina A. Harriott, Cherif F. Matta
This article examines, from historical and pedagogical perspectives, Alphonse Berget's anticipation of Earth-Moon travel in Le Ciel (Larousse, 1923), decades before the beginning o…
The Great Chicken-and-Egg of Chemistry: Bonding vs. Stability Revisited
Cherif F. Matta
The chemical bond is a central organizing concept in chemistry, yet it is absent from the molecular Hamiltonian and no "bond operator" exists. Bonding is therefore not a primitive…
The Critical 9365 Ã Diffuse Interstellar Band and C Association
Daniel Majaess, Tina A. Harriott, Halis Seuret +3
The detection of interstellar C has been debated for 30 years. The contested attribution of a weaker DIB at 9365 Ã was re-evaluated here on the basis of a Pearson correl…
Rotational Dynamics of ATP Synthase: Mechanical Constraints and Energy Dissipative Channels
Islam K. Matar, Peyman Fahimi, Cherif F. Matta
The proton motive force (PMF) across the inner mitochondrial membrane delivers approximately 0.2 eV of energy per proton, powering the FoF1-ATP synthase molecular motor. Here, we p…
