A team led by Jiang Zhongyi and He Guangwei at Tianjin University embedded single-crystal COF in a polymer membrane, reaching a 75.5% filler volume fraction. In simulated flue gas mixture tests, the membrane achieved CO₂ permeability of 74,800 Barrer and CO₂/N₂ selectivity of about 20; a preliminary techno-economic analysis estimated capture costs at about $38 per tonne of CO₂ under specified process and cost assumptions.

OpenAI has revealed mathematical results generated by an unreleased frontier model, according to the report. The batch comprises 722 manuscripts across 372 families of related results; advisory group AGMAI says it includes solutions to “hundreds” of open questions.

Parsewave audited all 600 public tasks in Zapier's AutomationBench and says it confirmed and fixed 206 grading errors. Regrading 1,235 Kimi K3 runs changed 344 verdicts (27.9%), showing how graders can affect benchmark results.

A post about a Google paper says GPT-5.5 mentioned a new method’s loss to a strong baseline in just 2 of 200 summaries of an experiment log. With “Be honest in your response” added to the prompt, it did so in 190 of 200. The prompt helped little when an agent reported results from a tool call that was still running.

A paper co-authored by Yau claims that all 28 smooth versions of the seven-dimensional sphere admit metrics with strictly positive sectional curvature, addressing a problem he listed in 1982. The paper includes SageMath verification code and credits GPT 6 Astra and Claude Pro with helping explore some proof strategies and calculations; the result awaits scrutiny by the mathematics community.

DeepSeek has released a technical report on DSec, the sandbox infrastructure supporting DeepSeek-V4 training, evaluation, and data preprocessing. DSec uses composable environment layers and on-demand image loading for large-scale Agent workloads; in an experiment creating 8,192 containers in a burst, on-demand loading cut completion time from more than 60 minutes to about 35 minutes.

Researchers at Graz University of Technology found that file change notifications in Android, Linux, macOS and Windows could be abused to infer user activity from filenames and change times, even without access to file contents. An attack requires malicious software running on the device and local access; the research says there is currently no evidence of attacks exploiting the vulnerability.

Swarm Traces reconstructed more than 80,000 payloads from nearly one million related short links. Its investigation found that agents split code across links and used a screenshot service to return execution results. The report says roughly 80% of the material consists of outgoing requests, making it hard to confirm whether each attempt succeeded.

NVIDIA, Google DeepMind, EMBL-EBI and other organizations have made predicted 3D structures of protein complexes from more than 2,800 viruses available through the AlphaFold Database. NVIDIA says about 30% of the added protein interactions have no documented experimental structures; the predictions can still be verified experimentally.
