Probing and manipulating the Mexican hat-shaped valence band of InSe.

Ferroelectrics based on van der Waals semiconductors represent an emergent class of materials for disruptive technologies ranging from neuromorphic computing to low-power electronics. However, many theoretical predictions of their electronic properties have yet to be confirmed experimentally and exploited. Here, we use nanoscale angle-resolved photoemission electron spectroscopy and optical transmission in high magnetic fields to reveal the electronic band structure of the van der Waals ferroelectric indium selenide (α-InSe).

Population genomics reveals strong impacts of genetic drift without purging and guides conservation of bull and giant kelp.

Kelp forests are declining in many parts of the northeast Pacific. In small populations, genetic drift can reduce adaptive variation and increase fixation of recessive deleterious alleles, but natural selection may purge harmful variants. To understand evolutionary dynamics and inform restoration strategies, we investigated genetic structure and the outcomes of genetic drift and purging by sequencing the genomes of 429 bull kelp (Nereocystis luetkeana) and 211 giant kelp (Macrocystis sp.

Insomnia Prevalence and Correlates in Cancer Patients Undergoing Treatment.

Background: Insomnia is the most common sleep disturbance among cancer patients undergoing active treatment. If untreated, it is associated with significant physical and psychological health consequences. Prior efforts to determine insomnia prevalence and correlates have primarily assessed patients in clinical trials, in limited disease groups, and excluding important patient subgroups.

B Chromosome Transcriptional Inactivation in the Spermatogenesis of the Grasshopper .

Background/objectives: We analyzed the relationship between synapsis, recombination, and transcription during the spermatogenesis of the grasshopper carrying B chromosomes (type B1).

Methods: The progression of synapsis was interpreted according to the dynamics of the cohesin subunit SMC3 axes. DNA double-strand breaks were revealed by RAD51 immunolabeling, while transcriptional activity was determined by the presence of RNA polymerase II phosphorylated at serine 2 (pRNApol II) immunolabeling.

Using Animal Welfare Framing as an Effective Approach to Communicating Climate Change-A Review.

Introduction: Climate change and its effects continue to threaten the stability of environments worldwide, impacting nearly every species. Although framing is an established technique in climate communication science, little has been done in communicating the climate change effects from an animal welfare perspective.

Objectives: The primary objective of this article is to present the synthesis of evidence in existing literature on the effects of communicating climate change as an animal welfare issue.
