Stoichiometric Binding of Cyclophilin‐A to The HIV‐1 Capsid Modulates Its Mechanoelastic Properties

open access: yesSmall, EarlyView.
The HIV‐1 capsid is a protein nanocapsule that must balance rigidity and flexibility to enter the cell nucleus. Atomic force microscopy simulations reveal that binding of the host protein Cyclophilin A tunes this mechanical response: partial coverage preserves deformability, while excessive binding induces brittleness and failure.

Unbiased Tandem System for Simultaneous Methane and Glycerol Upgrading to Formic Acid Under Ambient Conditions

open access: yesSmall, EarlyView.
A bias‐free photovoltaic‐photoelectrochemical tandem system enables simultaneous methane and glycerol upgrading to formic acid under ambient conditions. The cathode generates hydrogen peroxide for methane oxidation, while the photoanode efficiently oxidizes glycerol.

How We Simulate Nanopores

open access: yesSmall Methods, EarlyView.
Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

Optimizing multi-trait selection for profitability in Illinois wheat using a factor analytic mixed model and an economic selection index. [PDF]

open access: yesPlant Genome
Abstract Economic selection indices can improve the efficiency of selection for multiple traits, but they are underutilized in plant breeding due to limited research on the economic values of traits and a lack of well‐documented case examples employing economic indices.

Identity Impermanence as a Generic Social Process: The Malleability of Gender in Transgender and Nonbinary People's Lives

open access: yesSymbolic Interaction, EarlyView.
Drawing on 40 in‐depth interviews with transgender and nonbinary people, we found that respondents' gender identities or displays shifted day‐by‐day and audience‐by‐audience. The first describes respondents shifting their identities and displays based on feeling their way through gender while the latter describes feeling out an audience.

Five Decades of Dispute: A Triptych. E. J. Corey

open access: yesThe Chemical Record, EarlyView.
In his 2004 Priestley Medal address, E. J. Corey stated, “On May 4, 1964, I suggested to my colleague R. B. Woodward a simple explanation involving the symmetry of the perturbed (HOMO) molecular orbitals for the stereoselective cyclobutene/1,3‐butadiene and 1,3,5‐hexatriene/cyclohexadiene conversions that provided the basis for the further development ...
