Nematic order on a deformable vesicle with anchoring effects
This article proposes a new model to represent a vesicle membrane with internal nematic order whose equilibrium states depend on the competition between the bending, elastic and anchoring energies.

Leaf Lipid Alterations in Response to Heat Stress of Arabidopsis thaliana
Article measuring lipid levels with mass spectrometry to confirm the previously observed changes in Arabidopsis thaliana leaf lipids under three heat stress regimens. Additionally, in response to heat, increased oxidation of the fatty acyl chains of leaf galactolipids, sulfoquinovosyldiacylglycerols, and phosphatidylglycerols, and incorporation of oxidized acyl chains into acylated monogalactosyldiacylglycerols are shown. The authors also observed increased levels of digalactosylmonoacylglycerols and monogalactosylmonoacylglycerols. The hypothesis that a defect in sterol glycosylation would adversely affect regrowth of plants after a severe heat stress regimen was tested, but differences between wild-type and sterol glycosylation-defective plants were not detected.

Remodeling the epigenome and (epi)cytoskeleton: a new paradigm for co-regulation by methylation
This article is a commentary on coordinated use of methyl marks to remodel both the epigenome and the (epi)cytoskeleton, which opens the possibility for integrated regulation (referred to as ‘epiregulation’) of other higher-level functions, such as muscle contraction or learning and memory, and could even have evolutionary implications.

COVID-19 and the gender gap in work hours
Article using panel data from the US Current Population Survey to examine changes in mothers’ and fathers’ work hours from February through April 2020, the period of time prior to the widespread COVID-19 outbreak in the United States and through its first peak. Using person-level fixed effects models, we find that mothers with young children have reduced their work hours four to five times more than fathers.

AI, Arts & Design: Questioning Learning Machines
Article is an introduction to Artnodes issue No. 26, “AI, Arts & Design: Questioning Learning Machines" which addresses the question: Does generative and machine creativity in the arts and design represent an evolution of “artistic intelligence,” or is it a metamorphosis of creative practice yielding fundamentally distinct forms and modes of authorship?

Multitask deep-learning-based design of chiral plasmonic metamaterials
This article presents an end-to-end functional bidirectional deep-learning (DL) model for three-dimensional chiral metamaterial design and optimization. This ML model utilizes multitask joint learning features to recognize, generalize, and explore in detail the nontrivial relationship between the metamaterials’ geometry and their chiroptical response, eliminating the need for auxiliary networks or equivalent approaches to stabilize the physically relevant output. This model efficiently realizes both forward and inverse retrieval tasks with great precision, offering a promising tool for iterative computational design tasks in complex physical systems. Other potential applications include photodetectors, polarization-resolved imaging, and circular dichroism (CD) spectroscopy.
