Phase transitions, Dirac and Weyl semimetal states in MnGeBiTe.

Using angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT), an experimental and theoretical study of changes in the electronic structure (dispersion dependencies) and corresponding modification of the energy band gap at the Dirac point (DP) for topological insulator (TI) [Formula: see text] have been carried out with gradual replacement of magnetic Mn atoms by non-magnetic Ge atoms when concentration of the latter was varied from 10% to 75%. It was shown that when Ge concentration increases, the bulk band gap decreases and reaches zero plateau in the concentration range of 45-60% while trivial surface states (TrSS) are present and exhibit an energy splitting of 100 and 70 meV in different types of measurements. It was also shown that TSS disappear from the measured band dispersions at a Ge concentration of about 40%.

Comprehensive analysis of poly(A) tails in mouse testes and ovaries using Nanopore Direct RNA Sequencing.

Gametogenesis is a process in which dysfunctions lead to infertility, a growing health and social problem worldwide. In both spermatogenesis and oogenesis, post-transcriptional gene expression regulation is crucial. Essentially, all mRNAs possess non-templated poly(A) tails, whose composition and dynamics (elongation, shortening, and modifications) determine the fate of mRNA.

Gut microbes of the cecum versus the colon drive more severe lethality and multi-organ damage.

Intestinal perforations lead to a high risk of sepsis-associated morbidity and multi-organ dysfunctions. A perforation allows intestinal contents (IC) to enter the peritoneal cavity, causing abdominal infections. Right- and left-sided perforations have different prognoses in humans, but the mechanisms associated with different cecum and colon perforations remain unclear.

Cropland expansion links climate extremes and diets in Nigeria.

Climate change threatens smallholder agriculture and food security in the Global South. While cropland expansion is often used to counter adverse climate effects despite ecological trade-offs, the benefits for diets and nutrition remain unclear. This study quantitatively examines relationships between climate anomalies, forest loss from cropland expansion, and dietary outcomes in Nigeria, Africa's most populous country.

Chromatin conformation, gene transcription, and nucleosome remodeling as an emergent system.

In single cells, variably sized nanoscale chromatin structures are observed, but it is unknown whether these form a cohesive framework that regulates RNA transcription. Here, we demonstrate that the human genome is an emergent, self-assembling, reinforcement learning system. Conformationally defined heterogeneous, nanoscopic packing domains form by the interplay of transcription, nucleosome remodeling, and loop extrusion.

Here, we develop a general strategy to construct switchable and multifunctional metasurfaces.

Association Between Intra- and Postoperative Opioids in Opioid-Naïve Patients in Thoracic Surgery.

Background: As the opioid epidemic continues, a better understanding of the use of opioids in surgery is needed. We examined whether intraoperative opioid administration was associated with greater postoperative opioid use prior to discharge in opioid-naïve patients undergoing thoracic surgery. Further, we sought to determine predictors of higher intra- and postoperative opioid use including demographic and patient factors and hospital.

An eco-physiological model of forest photosynthesis and transpiration under combined nitrogen and water limitation.

Although the separate effects of water and nitrogen (N) limitations on forest growth are well known, the question of how to predict their combined effects remains a challenge for modeling of climate change impacts on forests. Here, we address this challenge by developing a new eco-physiological model that accounts for plasticity in stomatal conductance and leaf N concentration. Based on optimality principle, our model determines stomatal conductance and leaf N concentration by balancing carbon uptake maximization, hydraulic risk and cost of maintaining photosynthetic capacity.

A dataset of structural breaks in greenhouse gas emissions for climate policy evaluation.

The quantitative assessment of policies aimed at climate change mitigation requires rigorously identifying abnormal changes in greenhouse gas emissions. We present a new dataset of robust level changes in greenhouse gas emissions that cannot be explained by aggregate socioeconomic fluctuations. Modern methods of structural break identification based on two-way fixed effects models are employed to estimate the size of significant level changes in emissions.

Herein, we investigate the effects and mechanisms of CW and its bioactive constituent CW1 in reversing docetaxel (DTX) resistance in prostate cancer (PCa) cells. We investigated the reversal effects of CW and its bioactive constituent CW1 on 22Rv1/DTX cells in vitro and in vivo.

Regional Trends and Spatial Gradients of Total Column Methane over India, China, and USA─Implications for Emissions from Coal Mining and Oil/Gas Exploitation.

Observation-based verification of regional/national methane (CH) emission trends is crucial for transparent monitoring and mitigation strategy planning. Although surface observations track the global and sub-hemispheric emission trends well, their sparse spatial coverage limits our ability to assess regional trends. Dense satellite observations complement surface observations, offering a valuable means to validate emission trends, especially in regions where emissions changes are substantial but debated.

The utility of the Living Planet Index as a policy tool and for measuring nature recovery.

The Living Planet Index (LPI) is a leading global biodiversity indicator based on vertebrate population time series. Since it was first developed over 25 years ago, the LPI has been widely used to indicate trends in biodiversity globally, primarily reported every two years in the Living Planet Report. Based on relative abundance, a sensitive metric of biodiversity change, the LPI has also been applied as a tool for informing policy and used in assessments for several multilateral conventions and agreements, including the Convention on Biological Diversity 2010 Biodiversity Target and Aichi targets.
