This study examined why sodium is so difficult to store in graphite — a key problem for sodium-ion batteries — using two years of experimental data on highly oriented graphite samples. The results show that at room temperature, sodium can theoretically reach useful concentrations but cannot get there fast enough to be practical, and it enters the graphite as unusual bilayer structures rather than the ordered layers seen with other metals. These findings clarify a fundamental barrier to sodium-ion battery development and point toward the specific physical constraints that need to be solved.

Plain English
Researchers identified a specific type of liver cell — sinusoidal endothelial cells — as an early trigger of liver inflammation and scarring (fibrosis), acting through an epigenetic protein complex called PML/BRD4 that drives inflammatory signaling. Blocking this complex in mice reduced liver inflammation and fibrosis, and single-cell RNA sequencing confirmed the same aberrant cell population in fibrotic human liver tissue. Targeting PML/BRD4 in these cells could be a new therapeutic approach for chronic liver disease.

Plain English
This study compared two species of a plant genus with very different abilities to regenerate new plants from tissue culture, then used DNA methylation and gene expression analysis to find the molecular differences. Key genes in hormone signaling and stress response pathways showed different activity patterns between the high- and low-regeneration species. The findings provide a molecular blueprint for improving plant regeneration in this commercially important genus.

Plain English
The protein SLCO4C1 was found to act as a transporter that pulls cyclic AMP (cAMP) into liver cells, which suppresses fat production and protects against fatty liver disease (MASLD). Delivering extra copies of this gene to mouse livers reduced fat buildup, inflammation, and scarring, and a drug that raises cAMP levels had similar effects. This identifies the SLCO4C1–cAMP axis as a potential precision medicine target for the most common form of chronic liver disease.

Plain English
Researchers developed a simple scoring system (PEPS) to identify which hospitalized children in Malaysia with pneumonia are at highest risk of becoming severely ill. Using age under 6 months, incomplete vaccination, difficulty feeding, low oxygen, and anemia as key factors, the score accurately distinguished mild from moderate-to-severe cases (c-statistic 0.81). A validated tool like this could help doctors in similar healthcare settings make faster, better-informed treatment decisions.

Plain English
Cold plasma treatment was used to improve the process of attaching sugar molecules to milk proteins (caseins) as a strategy for reducing milk allergy. The treatment increased the number and variety of modification sites on the protein surface, particularly at spots that overlap with known allergy-triggering regions, which blocks immune recognition. This work provides a molecular-level explanation for how cold plasma-assisted glycation can reduce the allergenic potential of milk proteins.

Plain English
To improve gene therapy for Fabry disease — a genetic disorder where a key enzyme is missing — researchers engineered a better signal peptide and optimized the gene's DNA code to boost enzyme production. The best combination increased secreted enzyme activity nearly 7-fold in mice compared to the original gene sequence, and cleared the toxic metabolites that accumulate in the disease. These results support a more effective AAV-based gene therapy approach for Fabry disease.

Plain English
A protein called RAB3B, which helps cells manage vesicle traffic, was found to be significantly reduced in fetal membranes from pregnancies complicated by premature rupture — a major cause of preterm birth. When RAB3B was increased in amniotic cells in the lab, the cells migrated better, maintained stronger cell junctions, and were more resistant to breakdown. This identifies RAB3B as a potential therapeutic target for preventing preterm birth caused by membrane weakness.

Plain English
Nerol, a natural plant-derived compound, was tested for its toxicity across a range of organisms from bacteria to earthworms to understand its environmental safety profile. It showed measurable toxic effects at varying concentrations across all test species, but its biodegradability and ability to be metabolized by microbial communities suggest it won't persist long in the environment. These results support nerol as a potentially safer alternative to synthetic antimicrobial compounds, though not without ecological risk.

Plain English
This study looked at which factors predict death in infants with severe whooping cough who develop dangerously high white blood cell counts and are treated with exchange transfusion. Younger age at onset, higher white blood cell counts, and heart failure before the transfusion were the strongest predictors of death. Identifying these risk factors could help clinicians prioritize the most aggressive monitoring and support for the highest-risk patients.

Plain English
This review summarizes a class of small RNA molecules derived from transfer RNAs (tsRNAs) and their emerging roles in lung diseases, both cancerous and non-cancerous. These molecules regulate gene expression in response to stress and show altered patterns in pulmonary conditions, making them candidates for diagnostic biomarkers and treatment targets. The review highlights the clinical promise of tsRNAs while acknowledging that detection and functional validation remain technical challenges.

Plain English
Researchers tested a traditional Chinese herbal formula (Huangqi Guizhi Wuwu Decoction) in mouse models of pulmonary fibrosis and found it significantly reduced lung scarring, inflammation, and the progression of fibrosis. The mechanism involved suppressing the TGF-beta/Smad signaling pathway, rebalancing immune cells in the lung, and modulating cell cycle activity. These results support further investigation of this multi-target herbal treatment as an add-on strategy for pulmonary fibrosis.

Plain English
Researchers screened variants of adeno-associated virus (AAV) to find one that infects human T cells more efficiently at lower doses, which matters for making CAR-T cancer therapies more practical. The new variant, called Tot3, achieved comparable gene delivery to the standard AAV2 at 27 times lower concentration, and was used to simultaneously knock out PD-1 and add a cancer-targeting receptor in T cells, improving their tumor-killing ability in mice. This advance could make CAR-T cell manufacturing faster and less costly.

Plain English
Researchers tested whether monitoring a hospital's wastewater for respiratory viruses could predict patient infections in a geriatric hospital in Switzerland. Wastewater levels of SARS-CoV-2, influenza A, and RSV all correlated significantly with actual infections among patients, with wastewater signals for COVID-19 and influenza A appearing 3-5 days before confirmed cases. This supports hospital wastewater surveillance as an early warning tool for respiratory virus outbreaks in clinical settings.

Plain English
This meta-analysis of four large clinical trials examined middle meningeal artery embolization (MMAE) as a treatment for chronic subdural hematoma (blood pooling on the brain's surface). For patients treated without surgery, MMAE reduced treatment failure by 64% compared to conservative management, though it showed more modest benefits when added to surgery. The findings support a role for MMAE in non-surgical patients and suggest a risk-stratified approach for deciding when to use it alongside surgery.

Plain English
This review covers how mesenchymal stem cells (MSCs) — adult stem cells found in bone marrow and other tissues — promote the formation of new blood vessels (angiogenesis), particularly in neurological diseases. It describes strategies to enhance this angiogenic effect, including drug treatments, genetic modification, and new materials, and discusses how MSC-driven vascularization could help treat conditions like stroke and other ischemic brain diseases. The work frames MSC angiogenesis as a key therapeutic mechanism worth engineering more precisely.

Plain English
Two children with a fatal rare brain disease (CLN1 neuronal ceroid lipofuscinosis) were treated with fingolimod, an immune-modulating drug approved for multiple sclerosis, under compassionate use. One patient showed more than 50% reduction in a blood marker of brain damage (neurofilament light chain) over two years, suggesting reduced neuroinflammation, though no clear clinical improvement was seen. This small pilot supports a possible neuroprotective role for immune modulation in CLN1 and warrants further study.

Plain English
Researchers tested a simple ultrasound-based "sniff test" — measuring how much the subclavian vein narrows during a forceful sniff — as a non-invasive screening tool for central vein stenosis in dialysis patients. The test showed 84% sensitivity and 80% specificity, and combining it with clinical signs like arm swelling raised specificity to 95%. This offers a practical, radiation-free alternative to invasive angiography for identifying patients who need further workup.

Plain English
Researchers used plasma proteomics to identify early biological signals of long-term kidney transplant failure, analyzing blood samples collected years before graft loss occurred. A 113-protein signature enriched in immune and lipid metabolism pathways predicted graft failure significantly better than standard clinical markers like kidney function and protein in the urine. This suggests that blood protein profiling could catch transplant patients at risk of failure much earlier than current monitoring allows.

Plain English
This Australian registry study described treatment patterns and outcomes for patients with extragonadal germ cell tumors — rare cancers arising outside the testes, primarily in the chest or abdomen. Patients with retroperitoneal or seminoma tumors had excellent outcomes with no deaths, while those with primary mediastinal non-seminoma had the worst prognosis, with a 24-month survival of about 71%. The results confirm that tumor location is a strong predictor of outcome in this rare cancer group.
