A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

Low-molecular-weight hydroxyacids in marine atmospheric aerosol: evidence of a marine microbial origin [PDF]
Biogeosciences, 2014 Lactic acid (LA) and glycolic acid (GA), which are low-molecular-weight hydroxyacids, were identified in the particle and gas phases within the marine atmospheric boundary layer over the western subarctic North Pacific. A major portion of LA (81%) and GA

Journal of Approximation Theory, 1992 The authors study pairs \((u,v)\) of temperatures on \(\mathbb{R}\times]0,\infty[\) that satisfy the equations \[ D_ x u(x,t)=-iD_ t^{1/2} v(x,t) \qquad\text{and}\qquad iD_ t^{1/2} u(x,t)=D_ x v(x,t), \] which are analogous to the Cauchy-Riemann equations; here \(D_ t^{1/2}\) is a Weyl fractional derivative.

Disruption of SETD3‐mediated histidine‐73 methylation by the BWCFF‐associated β‐actin G74S mutation
FEBS Letters, EarlyView.The β‐actin G74S mutation causes altered interaction of actin with SETD3, reducing histidine‐73 methylation efficiency and forming two distinct actin variants. The variable ratio of these variants across cell types and developmental stages contributes to tissue‐specific phenotypical changes. This imbalance may impair actin dynamics and mechanosensitive
