Rubin Observatory's first LSST Camera release: 500k galaxies in the COSMOS field https://rubinobservatory.org/news/rubin-new-window-cosmos-field (https://news.ycombinator.com/item?id=49183079)

NSF–DOE Rubin Observatory Opens Deep Window on Famous Cosmic Field | Rubin Observatory

A new image from NSF–DOE Vera C. Rubin Observatory offers a spectacularly deep view into a famous region of sky known as the COSMOS field. Located in the constellation Sextans, COSMOS is one of the most observed patches of the Universe — and Rubin’s new image adds a powerful new view of this well-known cosmic landmark.

Zero-Mem: Zero-Token Memory Operations for LLM Agents https://arxiv.org/abs/2607.29377 (https://news.ycombinator.com/item?id=49178608)

Zero-Mem: Zero-Token Memory Operations for LLM Agents

LLM agents need memory to act consistently over long interactions, yet many systems use additional LLM calls to operate that memory. Generating intermediate records and mediating their retrieval adds recurring token and time costs, while omitted or merged details can obscure the original evidence. We ask whether structured memory access requires generation at all. Zero-Mem introduces \emph{zero-token memory operations}: no step outside final question answering invokes an LLM or consumes LLM input or output tokens; encoder computation is accounted for separately. Zero-Mem preserves original interaction traces as its source of record. It organizes the traces in two complementary ways. An entity--context graph exposes connections across interactions, while a temporal hierarchy preserves conversational locality and session state. For each query, Zero-Mem weighs the two views, retrieves from both, and follows their structure to recover supporting relations or surrounding context. Deterministic calibration first discards conflicting evidence and then keeps the reader's answer grounded in the retrieved traces. Only the final-QA reader invokes an LLM. Across long-memory and long-context question-answering benchmarks, Zero-Mem achieves competitive performance while eliminating LLM calls and LLM-token consumption from memory operations. With the same final-QA reader and context budget, it reduces memory-operation time cost by 57.6\% relative to the fastest compared baseline. Ablations support the contribution of the two views and their query-dependent coordination. Overall, the results show that structured agent memory need not generate an intermediate representation of the past. After peer review, the code and implementation details will be available at \textcolor{blue}{https://github.com/TheMoon0815/Zero-mem}.

Appeals Court Agrees with EFF that Building a Web Browser Doesn’t Violate the CFAA

The Ninth Circuit Court of Appeals has endorsed a commonsense technical interpretation of the Computer Fraud and Abuse Act (CFAA), a law not usually given to such interpretation. Amazon had sued Perplexity AI to try to shut down its Comet browser, claiming the browser’s optional agentic AI “...
