THE INTERNET IS THINKING
Science
Science investigates the natural world through observation, experiments, and mathematical models. Explore papers and developments in biology, medicine, materials, neuroscience, physics, climate, and mathematics; a reported finding is not necessarily established consensus.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗1212 classified signals in the fourteen-day window. Recent momentum: steady. These counts include signals awaiting readable evidence.
Recent sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Comparison of Lateral Decubitus versus Prone Lateral Lumbar Interbody Fusion Using Impact Scores: A Method to Quantify Intraoperative Supply Cost and Variability in Surgery. ↗
Surgical value metrics report intraoperative supply costs as aggregate institutional dollars, which do not identify which supply categories drive cost. To introduce the Impact Score, each supply category's percentage share of total intraoperative supply cost, as a descriptive framework and, using lateral decubitus (LD-LIF) versus prone lateral (PL-LIF) lateral lumbar interbody fusion as a proof of concept, to determine whether impact scores differ by supply category and align with median-cost rankings, whether exploratory outcome-based value metrics differ between approaches, and whether meani

Magnetic resonance imaging vs computed tomography for baseline imaging evaluation in acute basilar artery occlusion. ↗
The optimal imaging modality, magnetic resonance imaging (MRI) or computed tomography (CT), for identifying good treatment candidates among patients with acute basilar-artery occlusion (BAO) remains unclear. This was a post hoc analysis of the ATTENTION trial. Patients were categorized into MRI or CT groups according to the baseline imaging modality. The primary outcome was mRS 0-3 at 90 days. The secondary outcomes included mRS score shift on an ordinal scale, early neurological deterioration, time from stroke onset to arterial puncture, and time from onset to randomization. The safety outcom

Deep Learning for Protein Secondary-Structure Segmentation in Intermediate-Resolution Cryo-EM Maps: A Resolution-Stratified Benchmark Dataset and Controlled Evaluation ↗
Abstract Accurate segmentation of protein secondary structures in cryo-electron microscopy (cryo-EM) maps is crucial for protein tracing and atomic model building, yet remains challenging at intermediate resolutions. Although deep learning architectures have recently been applied to this task, there remains a lack of standardized evaluation protocols and systematic resolution-stratified analyses. Consequently, it remains unclear how segmentation performance varies across finer resolution ranges within the intermediate-resolution regime and how different volumetric segmentation architectures co…

Self-extending DNA recording with stochastic and programmed writing ↗
Recording cellular histories requires new information to accumulate without erasing earlier records. Here we introduce Infinite Printer, a CRISPR recording architecture that couples self-extension to regeneration of a writable terminal context. A self-targeting prime-editing guide RNA (stpegRNA) directs repeat extension, while base editing generates diversity in situ without a separate insertion template for each character state. Earlier sequence remains upstream of the renewed terminus, linking substrate growth with record retention. Auxiliary pegRNAs specify payloads within a write–renew–wri

How to assess evidence about Science
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
