Experts agree on 15 steps to improve antibody validation in research
A peer-reviewed study in PLOS Biology reports a consensus-based action plan for improving antibody validation, the testing that confirms an antibody works for a given experiment. Thirty-two international experts rated 33 proposed actions, and the panel agreed on 15 items that are both effective and feasible to implement by 2030. The study estimates that unvalidated antibodies waste over $1 billion a year in the United States alone.

AI chat system tested with patients before primary care visits
A peer-reviewed study in The Lancet tested the Articulate Medical Intelligence Explorer (AMIE), an artificial intelligence (AI) conversational system, with 114 patients before their urgent primary care appointments. No conversation safety stops were needed under the predefined criteria, and clinical evaluators rated its conversations favourably in 87-100% of cases. The authors call this an early feasibility result and say further research is needed.

Softening tumors helps nanodrugs enter cancer cells, study finds
A peer-reviewed study in PNAS found that stiff tumor tissue limited how well nanoparticle drugs entered cancer cells, and that softening the tumor in living animals increased nanoparticle penetration and uptake. Combining tumor softening with donafenib-loaded nanoparticles cut endpoint tumor weight by 87.8% compared with free donafenib, but also increased lung metastasis, which the authors describe as a potential efficacy-safety trade-off.

Neurodegenerative diseases share specific protein machinery, preprint finds
A preprint, not yet reviewed by other scientists, from bioRxiv, maps 16 disease proteins from 12 neurodegenerative disorders onto a shared network of 990 proteins. The authors report that these disorders share specific proteins beyond what their common processes alone would predict, and they name PRKN, HSPA8 and UBQLN2 as candidate shared vulnerabilities for testing.

Chinese herbal formula eased metabolic syndrome in rats, preprint reports
A preprint, not yet reviewed by other scientists, from bioRxiv, tested Huanglian Wendan Decoction (HLWDD), a multi-herb formula used in Chinese medicine, in rats fed a high-fat, high-sugar diet. The authors report that the formula improved obesity, abnormal blood fats, liver fat and inflammation, and they point to baicalin as a candidate active compound based on experiments in cultured cells.

Blood metabolites linked to frailty in older adults at dementia risk
A preprint, not yet reviewed by other scientists, from medRxiv, links blood metabolites to frailty in older adults at risk of dementia, studied at the Healthy Brain Ageing (HBA) clinic. Six of 10 metabolite clusters were associated with frailty at the start of the study, and the authors suggest some of them may form a panel of predictive biomarkers for at-risk patients.

Bacteria with several carbapenemase genes became more common, preprint finds
A preprint, not yet reviewed by other scientists, from bioRxiv, analyzes 1501 publicly available genomes of Enterobacterales bacteria that carry two or more carbapenemase genes, which confer resistance to carbapenem antibiotics. The authors report that cross-class combinations became more common over time, and they say the findings could support effective surveillance programmes.

Cancer cells' reliance on tRNA shifts between tumors and culture, preprint finds
A preprint, not yet reviewed by other scientists, from bioRxiv, maps which transfer RNA (tRNA) molecules cancer cells depend on, using large-scale gene-silencing screens across 16 cancer cell lines from seven tissue types. The authors report that these dependencies differ between tumors growing in living animals and cells grown in culture, while the protein machinery that reads the genetic code remained largely the same.

Immune cells that linger in aging tissue form protective structures, preprint finds
A preprint, not yet reviewed by other scientists, from bioRxiv, reports that mature conventional dendritic cells (cDCs) that stay in tissue help build lymphoid structures that appear with age. In mice, impaired cDC exit or cDC expansion induced such structures in several organs without pathology, and these structures gathered regulatory T cells that protected against inflammatory injury.

Complement protein inside kidney cells may drive fibrosis, preprint says
A preprint, not yet reviewed by other scientists, from bioRxiv, studies complement Factor B (FB) in injured kidneys and reports that FB acts inside proximal tubule cells, both in the cytoplasm and in the nucleus, to support metabolic adaptation to stress and maladaptive fibrotic repair. The authors say therapies that target complement outside cells may miss these intracellular functions, and that similar patterns appear in human kidney disease.

Blood imaging method flags sepsis in small preprint study
A preprint, not yet reviewed by other scientists, from medRxiv, reports a prospective study of 29 critically ill adults and 22 healthy controls, using label-free imaging of whole-blood samples with the Remoscope system. In a model optimized for ruling out sepsis, the authors report 100% sensitivity, meaning all sepsis cases in the study were caught, and 85.3% specificity, meaning most patients without sepsis were correctly cleared. They note abnormal shapes in white and red blood cells.

Wildfire smoke particles linked to higher dementia rates, preprint finds
A preprint, not yet reviewed by other scientists, from medRxiv, analyzes Medicare data for older US adults and links long-term exposure to wildfire smoke fine particulate matter (PM2.5) with higher rates of Alzheimer's disease and related dementias (ADRD). The carbonaceous, or carbon-based, fraction of the particles accounts for most of the estimated burden, which the authors put at 2,284 Alzheimer's cases and 11,142 ADRD cases per year.

Blood protein test can identify APOE4 carriers, preprint says
A preprint, not yet reviewed by other scientists, from medRxiv, tests whether measuring APOE4 protein in blood plasma can replace DNA testing to identify carriers of the APOE ε4 variant, a major genetic risk factor for Alzheimer's disease. The authors report near-perfect accuracy in three external cohorts, and say plasma APOE4 showed amyloid and clinical associations similar to those from DNA genotyping.

Rare gene variants rise with body weight, preprint finds
A preprint, not yet reviewed by other scientists, from medRxiv, examines rare and low-frequency genetic variants in 1138 adults from Kuwait and Qatar. The authors report that the burden of these variants rose with body mass index (BMI) across overweight, obese and morbidly obese groups, and that combinations of a finite set of low-frequency coding variants help shape polygenic obesity.

Mid-life physical activity linked to lower hip fracture risk, preprint finds
A preprint, not yet reviewed by other scientists, from medRxiv, is an observational study, which shows a link, not a cause, of 324,284 middle-aged adults in UK Biobank followed for 16 years. The authors report that moderately high physical activity in mid-life was linked to lower hip fracture risk, with the lowest risk at about one hour a day, and that vigorous activity showed the strongest link, with the benefit leveling off at higher volumes.

Many urine infections in India resist common antibiotics, preprint finds
A preprint, not yet reviewed by other scientists, from medRxiv, analyzes prescription and diagnostic data from Tata 1mg for 2023 to 2025. Of 25.7 million medicines prescribed, 10.8% were antibiotics, and Escherichia coli (E. coli) from urine cultures resisted ceftriaxone in 53.6% and ciprofloxacin in 57.0% of cases. In this exploratory analysis, resistance to some 'Watch' antibiotics preceded changes in resistance to 'Access' antibiotics by about 3-6 months.

Genetic risk scores often differ in accuracy across ancestry groups, preprint finds
A preprint, not yet reviewed by other scientists, from medRxiv, evaluates 3,994 published polygenic scores, which predict traits from many genetic variants, in the CCPM biobank of ancestrally diverse people. The authors find that predictive effects often differ across ancestry groups, which they say threatens equity in downstream applications, and that accuracy depends on whether a score is continuous or thresholded.

Jev decision model trails Claude models at multi-symptom diagnosis, preprint finds
A preprint, not yet reviewed by other scientists, from medRxiv, tests Jev 1.13, a decision model from TypeSafe AI, against two Claude language models on diagnosis tasks. On 1,000 synthetic patients, Jev's top-1 accuracy was 72.0%, compared with 79.5% for Claude Opus 5 without reasoning and 87.4% for Claude Opus 5.5, and Jev assigned zero probability to the correct diagnosis in 6.2% of cases. The authors conclude that calibration claims for clinical decision models should be tested on clinical tasks.
