Extensive efforts to gather materials data have largely overlooked potential data redundancy. In this study, we present evidence of a significant degree of redundancy across multiple large datasets for various material properties, by revealing that up to 95% of data can be safely removed from machine learning training with little impact on in-distribution prediction performance. The redundant data is related to over-represented material types and does not mitigate the severe performance degradation on out-of-distribution samples. In addition, we show that uncertainty-based active learning algorithms can construct much smaller but equally informative datasets. We discuss the effectiveness of informative data in improving prediction performance and robustness and provide insights into efficient data acquisition and machine learning training. This work challenges the “bigger is better” mentality and calls for attention to the information richness of materials data rather than a narrow emphasis on data volume. Big data is crucial for machine learning, but the redundancies in the datasets are rarely studied. Here the authors reveal significant redundancy in large materials datasets, showing that up to 95% of data can be removed without impacting prediction accuracy.

Zika virus (ZIKV) is a mosquito-transmitted virus that has caused significant public health concerns around the world, partly because of an association with microcephaly in babies born to mothers who were infected with ZIKV during pregnancy. As a recently emerging virus, little is known as to how the virus interacts with the host cell machinery. A yeast-2-hybrid screen for proteins capable of interacting with the ZIKV E protein domain III, the domain responsible for receptor binding, identified 21 proteins, one of which was the predominantly ER resident chaperone protein GRP78. The interaction of GRP78 and ZIKV E was confirmed by co-immunoprecipitation and reciprocal co-immunoprecipitation, and indirect immunofluorescence staining showed intracellular and extracellular co-localization between GRP78 and ZIKV E. Antibodies directed against the N-terminus of GRP78 were able to inhibit ZIKV entry to host cells, resulting in significant reductions in the levels of ZIKV infection and viral production. Consistently, these reductions were also observed after down-regulation of GRP78 by siRNA. These results indicate that GRP78 can play a role mediating ZIKV binding, internalization and replication in cells. GRP78 is a main regulator of the unfolded protein response (UPR), and the study showed that expression of GRP78 was up-regulated, and the UPR was activated. Increases in CHOP expression, and activation of caspases 7 and 9 were also shown in response to ZIKV infection. Overall these results indicate that the interaction between GRP78 and ZIKV E protein plays an important role in ZIKV infection and replication, and may be a potential therapeutic target.

Recent advances in machine learning (ML) have led to substantial performance improvement in material database benchmarks, but an excellent benchmark score may not imply good generalization performance. Here we show that ML models trained on Materials Project 2018 can have severely degraded performance on new compounds in Materials Project 2021 due to the distribution shift. We discuss how to foresee the issue with a few simple tools. Firstly, the uniform manifold approximation and projection (UMAP) can be used to investigate the relation between the training and test data within the feature space. Secondly, the disagreement between multiple ML models on the test data can illuminate out-of-distribution samples. We demonstrate that the UMAP-guided and query by committee acquisition strategies can greatly improve prediction accuracy by adding only 1% of the test data. We believe this work provides valuable insights for building databases and models that enable better robustness and generalizability.

The hypoglossal nerve (HN) provides motor innervation to tongue muscles responsible for tongue movement, speech, mastication, swallowing, respiratory functions and management of oral secretions. Injury, compression, entrapment or lesions of the HN at any point along its path can result in HN palsy and subsequent dysphagia, dysarthria and tongue muscular atrophy. A combined imaging approach is required to investigate the HN and causes of HN palsy. Magnetic resonance imaging (MRI) and computed tomography (CT) imaging are used to investigate the intracranial HN and where it emerges in the upper neck. The extracranial HN can be assessed by sonographic imaging along with the muscles directly and indirectly innervated by the HN. Ultrasound imaging can be challenging without an appropriate understanding of the detailed relative anatomy of the HN and the muscles it innervates, the associated sonographic technique and sonographic appearances, all of which are outlined in this paper. The hypoglossal nerve (HN) provides motor innervation to tongue muscles responsible for tongue movement, speech, mastication, swallowing, respiratory functions and management of oral secretions. The intracranial component of the HN can be demonstrated on magnetic resonance imaging and the extracranial component can be demonstrated with sonographic imaging. Injury, compression, entrapment, or lesions of the HN can occur at any point along its path and cause HN palsy. Imaging, as outlined in this paper, can be used to identify HN changes.

To compare patient-reported outcomes and visual performance after implantation of a conventional monofocal toric intraocular lens (Clareon, Alcon) versus a monofocal-plus toric intraocular lens (Eyehance, Johnson & Johnson Vision). Single-center retrospective observational study with cross-sectional postoperative survey. Vance Thompson Vision, West Fargo, North Dakota. Patients who underwent bilateral cataract surgery between 2020 and 2025 with monofocal (Clareon) or monofocal-plus (Eyehance) toric IOLs were included. Chart data included uncorrected and best-corrected visual acuities, lens power, prior LASIK, and postoperative YAG capsulotomy or laser fine-tune. Eligible patients completed an 11-question telephone survey assessing satisfaction, glare/haloes, spectacle use across visual tasks, and willingness to choose the same lens again. Differences between groups were analyzed using Fisher's exact, Chi-square, and Wilcoxon rank-sum tests. Multivariable ordinal logistic regression evaluated independent predictors of satisfaction. In total, 92 patients completed the survey (response rate 83.6%). Distance UCVA and BCVA were excellent and not significantly different between groups. Eyehance patients demonstrated better near UCVA (p < 0.001), consistent with its optical design. Spectacle independence across intermediate and near tasks was broadly similar, showing only a non-significant trend toward greater independence for computer use in the Eyehance group. Eyehance patients reported glare more frequently (p = 0.034), but glare-related bother remained low and did not differ significantly between groups. Clareon patients reported being \"very satisfied\" more frequently (p < 0.001), but adjusted ordinal regression showed higher overall satisfaction odds in the Eyehance group (adjusted OR 2.11, 95% CI 1.08-4.18, p = 0.031). Both toric IOL platforms provided excellent distance vision and favorable patient-reported outcomes. The monofocal-plus Eyehance design offered superior uncorrected near vision with increased glare frequency, without significant differences in glare bother between groups. These findings support individualized counseling and shared decision-making when choosing between conventional monofocal and monofocal-plus toric IOLs.

To provide long-term intraocular pressure (IOP) and ocular hypotensive medication usage outcomes through 36 months for patients treated with canaloplasty and trabeculotomy (OMNI Surgical System) combined with cataract surgery as participants in the GEMINI study. Eleven ophthalmology practices in 10 US states. Non-interventional 36-month extension of the 12-month, prospective, multicenter, GEMINI study. GEMINI patients had visually significant cataract, mild-to-moderate glaucoma (ICD-10 guidelines), medicated IOP <33 mmHg, and unmedicated mean diurnal IOP (DIOP) (after washout) 21-36 mmHg. Patients from GEMINI were eligible for inclusion. Outcome measures were reduction in mean unmedicated DIOP, reduction in mean IOP-lowering medications, percent of eyes with ≥20% reduction in unmedicated DIOP, and percent of eyes with unmedicated DIOP ≥6 and ≤18 mmHg. A total of 66 patients provided consent and were enrolled. Mean (SD) unmedicated DIOP was 23.1 (2.7) mmHg at baseline, 16.7 (4.1), 16.3 (3.3) at 24 and 36 months; mean reductions of 6.2 (4.1) and 6.9 (3.4) mmHg. Twelve-month IOP at the end of GEMINI was 15.6 mmHg. The proportion of eyes with ≥20% reduction in IOP was 77% and 78% (months 24 and 36) compared to 87% at month 12 from GEMINI. About 68% of patients had an IOP between 6 and 18 mmHg at 24 months and 71% at 36 months. Mean IOP-lowering medications was 1.7 at baseline, which was reduced to 0.4 (24 months, -1.3) and 0.3 (36 months, -1.4). About 74% of patients (46 of 62) were medication free at 36 months. GEMINI demonstrated 12-month effectiveness of canaloplasty and trabeculotomy with OMNI combined with cataract surgery for IOP and medication reduction in mild-to-moderate glaucoma. However, longer-term data is key to the decision making in the selection of a surgical treatment. This GEMINI extension demonstrates that the 12-month outcomes from GEMINI were sustained through 36 months.

Plant–microbe interactions play crucial roles in species invasions but are rarely investigated at the intraspecific level. Here, we study these interactions in three lineages of a globally distributed plant, Phragmites australis. We use field surveys and a common garden experiment to analyze bacterial communities in the rhizosphere of P. australis stands from native, introduced, and Gulf lineages to determine lineage-specific controls on rhizosphere bacteria. We show that within-lineage bacterial communities are similar, but are distinct among lineages, which is consistent with our results in a complementary common garden experiment. Introduced P. australis rhizosphere bacterial communities have lower abundances of pathways involved in antimicrobial biosynthesis and degradation, suggesting a lower exposure to enemy attack than native and Gulf lineages. However, lineage and not rhizosphere bacterial communities dictate individual plant growth in the common garden experiment. We conclude that lineage is crucial for determination of both rhizosphere bacterial communities and plant fitness.

Arginine vasopressin (AVP) is synthesised in magnocellular neurons (MCNs) of supraoptic nucleus (SON) and paraventricular nucleus (PVN) of the hypothalamus. In response to the hyperosmotic stressors of dehydration (complete fluid deprivation, DH) or salt loading (drinking 2% salt solution, SL), AVP synthesis increases in MCNs, which over-burdens the protein folding machinery in the endoplasmic reticulum (ER). ER stress and the unfolded protein response (UPR) are signaling pathways that improve ER function in response to the accumulation of misfold/unfold protein. We asked whether an ER stress response was activated in the SON and PVN of DH and SL rats. We observed increased mRNA expression for the immunoglobulin heavy chain binding protein (BiP), activating transcription factor 4 (Atf4), C/EBP-homologous protein (Chop), and cAMP responsive element binding protein 3 like 1 (Creb3l1) in both SON and PVN of DH and SL rats. Although we found no changes in the splicing pattern of X box-binding protein 1 (Xbp1), an increase in the level of the unspliced form of Xbp1 (Xbp1U) was observed in DH and SL rats. CREB3L1, a novel ER stress inducer, has been shown to be activated by ER stress to regulate the expression of target genes. We have previously shown that CREB3L1 is a transcriptional regulator of the AVP gene; however, a role for CREB3L1 in the response to ER stress has yet to be investigated in MCNs. Here, we used lentiviral vectors to introduce a dominant negative form of CREB3L1 (CREB3L1DN) in the rat SON. Expression of CREB3L1DN in the SON decreased Chop and Xbp1U mRNA levels, but not BiP and Atf4 transcript expression. CREB3L1 is thus implicated as a transcriptional mediator of the ER stress response in the osmotically stimulated SON.

The \"ship\" of the Arabian and North African deserts, the one-humped dromedary camel (Camelus dromedarius) has a remarkable capacity to survive in conditions of extreme heat without needing to drink water. One of the ways that this is achieved is through the actions of the antidiuretic hormone arginine vasopressin (AVP), which is made in a specialised part of the brain called the hypothalamo-neurohypophyseal system (HNS), but exerts its effects at the level of the kidney to provoke water conservation. Interestingly, our electron microscopy studies have shown that the ultrastructure of the dromedary HNS changes according to season, suggesting that in the arid conditions of summer the HNS is in an activated state, in preparation for the likely prospect of water deprivation. Based on our dromedary genome sequence, we have carried out an RNAseq analysis of the dromedary HNS in summer and winter. Amongst the 171 transcripts found to be significantly differentially regulated (>2 fold change, p value <0.05) there is a significant over-representation of neuropeptide encoding genes, including that encoding AVP, the expression of which appeared to increase in summer. Identification of neuropeptides in the HNS and analysis of neuropeptide profiles in extracts from individual camels using mass spectrometry indicates that overall AVP peptide levels decreased in the HNS during summer compared to winter, perhaps due to increased release during periods of dehydration in the dry season.
