Mathematicians Build Long-Awaited Graph SandwichThe proof of a decades-old conjecture has given researchers a new way to understand complex networks.
Paulina Rowińska explains how Behague, Iľkovič, and Montgomery completed Kim and Vu's sandwich conjecture, letting hard properties of random regular graphs follow from easier binomial-graph results.

RoboHarm: Do Frontier Robot Policies Refuse Unsafe Instructions?
RoboHarm tests whether frontier robot policies refuse unsafe instructions: refusal vs completion rates across models, tasks like toaster/screwdriver hazards, and scoring details.

Human brain is two separate organs, Stanford Medicine-led research finds
Stanford Medicine–led research finds the human brain is two distinct organs—the cerebrum and the brainstem—opening new avenues for studying diseases that selectively affect the brainstem.

The Right Answer Is Not a Proof: Put Verification Inside the Reasoning Loop
Cognaptus explains PRoSFI: a 7B model emits small machine-checkable reasoning steps that Lean/Z3 can verify, raising measured soundness far more than final-answer accuracy alone on ProverQA-Hard.

An Empirical Study of Harness Design for Coding Agents
Fan et al. ablate planning, action space, and context management in a fixed coding-agent loop across 176 SWE-Bench/Terminal-Bench settings, finding when context management, planning, and predefined tools help—and when bash-only is enough.

Scaling Discovery through Test-Time Communication
Research paper showing that test-time communication among identical agents sharing discoveries can beat independent parallel search on ARC-AGI-3 and transfer to research tasks like polyomino packing and MNIST compression.

2026 DeGoogle Mobile Telemetry Study: 72-Hour Packet Capture Dataset
An empirical 72-hour Wireshark capture comparing idle stock Pixel Android to GrapheneOS finds ~348 outbound Alphabet requests per hour on stock versus near-zero without Google services, with a public CC BY 4.0 CSV.

Infinite-Parameter LLMs: Generating and Adapting Weights from Live Data
Research proposing infinite-parameter LLMs that generate and adapt weights from live data streams, rather than relying only on a fixed pretrained parameter set.

Breaking the 1.58-bit Barrier for Ternary LLMs
Breaking the 1.58-bit Barrier for Ternary LLMs Abstract Ternary Large Language Models (LLM) store every weight as one of three symbols , so the cost of a ternary model is conventionally referenced to the information-theoretic bits per weight. The prevailing deployment format…

Asking Authors About Their Own Papers
TMLR Editor-in-Chief Nihar B. Shah interviewed authors of 10 papers slated for desk rejection; many could not answer basic questions about their own submissions as desk-reject rates rose from ~6% to ~53%.

Dream-RSI: Recursive Self-Improvement through Evolving Worlds
Google researchers present Dream-RSI: treat discovery trees as exact replay simulators so agents can offline-evaluate exploration policies—cutting discovery cost up to 162× while leaving coding-model weights unchanged.

Training a 4B model to produce 81% faster query plans than Postgres
Leis et al. asked this exact question in 2015. Then, they asked it again 10 years later. Despite an enormous body of research spanning a decade since their original exploration, they found that query optimizers continue to leave much to be desired. I was surprised when I first learned about this. A Postgres database should know everything about the stuff that lives in its tables, no? How hard can it be?

The Pain Axis: LLMs Represent Self-Directed Harm and Act to Relieve It
Tagliabue, Dung, and Berg identify a linear “pain axis” in 25 open-weight models that responds to self-directed harm and steers models toward relief—even when that costs the user—sparking debate on functional signatures vs sentience.

'Fingerprints' inside the Sun could reveal if it once swallowed a planet
A new study published in Monthly Notices of the Royal Astronomical Society proposes that if the Sun engulfed a super-Earth early in its history, that event would have left detectable chemical and structural signatures in the solar interior that helioseismology could potentially identify today.

RTK reports huge token savings, but our cost benchmarks disagree
Quesma ran RTK (Rust Token Killer) against Terminal-Bench 2.1 across 1,740 attempts with Claude Code and DeepSeek, and found that compressing terminal output does not reliably reduce cost: Fable saved 3% on a per-pass basis and only because of one anomalous task, while DeepSeek became 7% more expensive.
