The past decade has seen remarkable progress in identifying genes that, when impacted by deleterious coding variation, confer high risk for autism spectrum disorder (ASD), intellectual disability, and other developmental disorders. However, most underlying gene discovery efforts have focused on individuals of European ancestry, limiting insights into genetic risks across diverse populations. To help address this, the Genomics of Autism in Latin American Ancestries Consortium (GALA) was formed, presenting here the largest sequencing study of ASD in Latin American individuals (n>15,000).

Electrically Modulated Multilevel Optical Chirality in GdFeCo Thin Films.

ACS Appl Electron Mater

January 2025

Department of Applied Physics, National Pingtung University, No. 4-18, Minsheng Road, 90044 Pingtung, Taiwan.

This study introduces a simple approach to dynamically control multilevel optical ellipticity in ferrimagnetic GdFeCo alloys by switching the spin orientation through Joule heating induced by electrical current, with the assistance of a low magnetic field of 3.5 mT. It is demonstrated that selecting specific compositions of Gd (FeCo) alloys, with magnetic compensation temperatures near or above room temperature, allows for significant manipulation of the circular dichroism (CD) effect.

Tidal Deformation and Dissipation Processes in Icy Worlds.

Space Sci Rev

January 2025

Faculty of Mathematics and Physics, Department of Geophysics, Charles University, V Holesšovičkách 2, Praha, Praha 8 180 00 Czech Republic.

Tidal interactions play a key role in the dynamics and evolution of icy worlds. The intense tectonic activity of Europa and the eruption activity on Enceladus are clear examples of the manifestation of tidal deformation and associated dissipation. While tidal heating has long been recognized as a major driver in the activity of these icy worlds, the mechanism controlling how tidal forces deform the different internal layers and produce heat by tidal friction still remains poorly constrained.

Differential encoding of odor and place in mouse piriform and entorhinal cortex.

bioRxiv

January 2025

Department of Neuroscience and Carney Institute for Brain Science, Brown University, Providence, USA.

The integration of olfactory and spatial information is critical for guiding animal behavior. The lateral entorhinal cortex (LEC) is reciprocally interconnected with cortical areas for olfaction and the hippocampus and thus ideally positioned to encode odor-place associations. Here, we used mini-endoscopes to record neural activity in the mouse piriform cortex (PCx) and LEC.

Bacteriophage research has experienced a renaissance in recent years, owing to their therapeutic potential and versatility in biotechnology, particularly in combating antibiotic resistant-bacteria along the farm-to-fork continuum. However, certain pathogens remain underexplored as targets for phage therapy, including the zoonotic pathogen which causes infections in pigs and humans. Despite global efforts, the genome of only one infective phage has been described.

We measure the response of open-cell polyurethane foams filled with a dense suspension of fumed silica particles in polyethylene glycol at compression speeds spanning several orders of magnitude. The gradual compressive stress increase of the composite material indicates the existence of shear rate gradients in the interstitial suspension caused by wide distributions in pore sizes in the disordered foam network. The energy dissipated during compression scales with an effective internal shear rate, allowing for the collapse of three data sets for different pore-size foams.

Exploring a Novel Adsorbent for CO Capture and Gas Separation.

ACS Appl Mater Interfaces

January 2025

Université de Caen Normandie, ENSICAEN, CNRS, LCS, Laboratoire Catalyse et Spectrochimie, Caen 14000, France.

The urgent need to mitigate carbon emissions has spurred research into small-pore zeolites as cost-effective options for CO capture by solid adsorbents, particularly in postcombustion and biogas separation applications. In this study we investigate levyne (LEV-type) zeolite, a largely unexplored material for CO adsorption, as a novel adsorbent for CO capture and gas separation. Using seed-assisted synthesis approaches and different synthesis conditions, nanosized and micron-sized LEV zeolites were synthesized and characterized in terms of synthesis pathways, morphology, crystal size, and chemical composition.

Ensemble Density Functional Theory of Ground and Excited Energy Levels.

J Phys Chem A

January 2025

Laboratoire de Chimie Quantique, Institut de Chimie, CNRS/Université de Strasbourg, 4 rue Blaise Pascal, 67000 Strasbourg, France.

A Kohn-Sham (KS) density-functional energy expression is derived for any (ground or excited) state within a given many-electron ensemble along with the stationarity condition it fulfills with respect to the ensemble density, thus giving access to both physical energy levels and individual-state densities, in principle exactly. We also provide working equations for the evaluation of the latter from the true static ensemble density-density linear response function. Unlike in Gould's recent ensemble potential functional approach to excited states [arXiv:2404.

The efficient functioning of dye-sensitized solar cells (DSSCs) is governed by the interplay of three essential components: the semiconductor, the dye, and the electrolyte. While the impact of the electrolyte composition on the device's performance has been extensively studied in n-type DSSCs, much less is known about p-type-based devices. Here, we investigate the effect of potential-determining ions on the energetics and stability of dye-sensitized NiO surfaces by using electrochemical, ab initio molecular dynamics simulations, and ab initio electronic structure calculations.

All-solid-state lithium batteries (ASSBs) are among the most promising energy storage technologies, particularly for electric vehicles, due to their enhanced safety. However, performances of these systems are still hindered by interfacial side reactions at electrode/electrolyte interfaces, especially when sulfide electrolytes are used, and additional issues of mechanical nature. In this work, an ASSB system composed of an argyrodite (LiPSCl) electrolyte, a lithium-rich sulfide cathode (LiTiS) operating at moderate voltage, and a lithium metal anode is investigated.

Population matrix models are routinely used to study the demography of wild populations and to guide management choices. When vital rates are unknown for a specific population or life history stage, researchers often replace them with estimates from other populations of the same species. Such 'hybrid' matrices might ignore among-population life history variation and lead to incorrect inferences.
