1. A Mercury Rover Could Explore the Planet by Sticking to the Terminator (www.universetoday.com)

A Mercury lander mission would create opportunities to sample unique geological features. However, extreme temperature fluctuations on Mercury’s surface pose challenges for exploration on the planetary surface. In a narrow region near the terminator, temperate conditions would allow a rover to run on solar power and collect data and surface samples without needing to withstand the extreme heat.

10. The Universal Constraint Engine: Neuromorphic Computing Without Neural Networks (zenodo.org)

We introduce the Universal Constraint Engine (UCE), a system for generating emergent multi-state architectures from declarative constraint rules over conserved quantities. Unlike conventional neural network architectures that rely on learned weights, gradient descent, and massive training corpora, UCE derives computational behaviors -- including memory, logic, hysteresis, and oscillation -- directly from symbolic constraints without any training phase. The system comprises four layers: a Rule Definition Layer, a Constraint Solver Layer, an Emergent Behavior Engine, and an Embodiment Mapper for translating symbolic architectures into hardware implementations spanning FPGA, neuromorphic, spintronic, and quantum substrates. Worked examples demonstrate that minimal rule sets produce non-trivial emergent behaviors analogous to SR latches, biological oscillators, and write-gated memory cells. Patent pending: U.S. Provisional Application No. 64/036,854.

18. Sir-Bench – benchmark for security incident response agents (arxiv.org)

We present SIR-Bench, a benchmark of 794 test cases for evaluating autonomous security incident response agents that distinguishes genuine forensic investigation from alert parroting. Derived from 129 anonymized incident patterns with expert-validated ground truth, SIR-Bench measures not only whether agents reach correct triage decisions, but whether they discover novel evidence through active investigation. To construct SIR-Bench, we develop Once Upon A Threat (OUAT), a framework that replays real incident patterns in controlled cloud environments, producing authentic telemetry with measurable investigation outcomes. Our evaluation methodology introduces three complementary metrics: triage accuracy (M1), novel finding discovery (M2), and tool usage appropriateness (M3), assessed through an adversarial LLM-as-Judge that inverts the burden of proof -- requiring concrete forensic evidence to credit investigations. Evaluating our SIR agent on the benchmark demonstrates 97.1% true positive (TP) detection, 73.4% false positive (FP) rejection, and 5.67 novel key findings per case, establishing a baseline against which future investigation agents can be measured.
