A new arXiv preprint proposes a protocol that hides which database entry a client wants from the server holding it, though the work is theoretical and awaits peer review.
Three mathematicians report that among the infinitely many ways this geometric flow can lose smoothness, a single self-similar shape survives small disturbances, a result proved with computer assistance, restricted to a symmetric class of perturbations, and not yet peer reviewed.
In a study of Orang Asli adults across Peninsular Malaysia, current lifestyle was linked to shifts in 1,428 immune genes versus 223 for childhood conditions, though this bioRxiv preprint has not yet been peer reviewed.
In a survey of 306 older Korean Americans in low-income Los Angeles senior housing, sleep quality accounted for roughly 24 percent of the association between incontinence and depressive symptoms, though the one-time snapshot cannot establish cause.
An international team describes eight new fungal genera and 28 new species from tombstones, dead leaves, quarantine-intercepted limes and a cornea in India, part of an annual effort to close a gap of roughly three million undescribed fungi.
A cross-sectional study of 436 people over 60 in Kumarapalayam, Tamil Nadu, found worse hearing among those living within 100 metres of powerlooms, though its snapshot design cannot prove the noise caused the damage.
A review of targeted PET imaging argues that tracers aimed at specific tumor molecules outperform the standard sugar-based scan, though most of the strongest evidence so far comes from animal work and small early-phase trials.
The notice from Frontiers in Microbiology contains no new data and no change to the study of dark septate endophytic fungi in sandy eastern Inner Mongolia; the only thing wrong was the name and number of the grant that paid for it.
In a cohort of 324 three- to five-year-olds, girls carrying the premutation were about three times as likely to have parent-reported sleep problems, though the finding rests entirely on parent questionnaires.
Ultrasound scans of 77 bycaught turtles found high gas loads within an hour of surfacing and much lower loads hours later, in a preprint that has not yet been peer reviewed.
In 16 novices who each sat through up to 24 lab meditation sessions with EEG caps on, front and back alpha rhythms pushed subjective mindfulness in opposite directions, though the sample is small and the effects are correlational.
Fiber photometry in freely foraging mice showed AgRP neuron activity falling steadily as animals neared a food source and rising as they left, though the work is a preprint and has not yet been peer reviewed.
Fifty adolescents living with HIV in Lima, Peru scored higher on a depression quiz after one session with a chatbot they helped design, though the pilot had no control group and no follow-up beyond that single visit.
A Spanish team re-measured CRP, TNF-alpha, IL-1beta and IL-6 in 85 people with WHO-defined long COVID and 85 matched recovered controls, and found no sign of ongoing systemic inflammation; the work is a preprint and has not yet been peer reviewed.
A review of cardiac cell migration argues that a well-documented laboratory phenomenon, cells physically moving through heart tissue after damage, has produced almost no clinical treatments, and explains where the gaps are.
Jean Della Dora and Stephen M. Watt describe algorithms for dividing and factoring linear ordinary differential operators, written for a Stanford conference whose proceedings never appeared; the authors have now posted it to arXiv for the historical record.
In a five-practice Australian pilot, the software could not read doctors' free-text notes, where 98 percent of the relevant detail lived, and nearly all the flagged patients were being followed up anyway.
In 52 healthy adults learning a joystick task, people carrying lower-dopamine gene variants improved less when told they were beating others than when they got plain timing feedback; the effect was small, exploratory, and needs replication.
In a study of 32 Italian university students with dyslexia and 60 without, both groups picked up the rules of an invented symbol grammar, and the dyslexic readers leaned harder on frequency patterns to compensate.
A new arXiv preprint from a University of North Carolina statistics group argues that patient-simulating models fail in two specific ways, and it is a conceptual argument rather than an experiment with data.
