Abstract: Embodied LLMs endow robots with high-level task reasoning, but they cannot reflect on what went wrong or why, turning deployment into a sequence of independent trials where mistakes repeat rather than accumulate into experience. Drawing upon human reflective practitioners, we introduce Reflective Test-Time Planning, which integrates two modes of reflection: \textit{reflection-in-action}, where the agent uses test-time scaling to generate and score multiple candidate actions using internal reflections before execution; and \textit{reflection-on-action}, which uses test-time training to update both its internal reflection model and its action policy based on external reflections after execution. We also include retrospective reflection, allowing the agent to re-evaluate earlier decisions and perform model updates with hindsight for proper long-horizon credit assignment. Experiments on our newly-designed Long-Horizon Household benchmark and MuJoCo Cupboard Fitting benchmark show significant gains over baseline models, with ablative studies validating the complementary roles of reflection-in-action and reflection-on-action. Qualitative analyses, including real-robot trials, highlight behavioral correction through reflection.

Satellite data reveals new insights into sustainable groundwater usage in the Hollywood Basin
Groundwater is a critical resource in Southern California, where long-term drought and climate change place increasing pressure on local aquifers. Some regions, like the Hollywood Basin (a small region in and around the West Hollywood neighborhood), are increasing their reliance on these aquifers in order to reduce the amount of water imported from elsewhere. A new Caltech-led study provides the most detailed picture to date of how the Hollywood Basin responds to groundwater usage, revealing th…

I post a lot here and on Maker Forums Discourse, and have kind of not gotten around to blogging for a while. But today I had time to reflect on my first full year of #HamRadio — this new hobby has surprised me in a lot of (good) ways.

France Bets on Carbon Capture as North Sea Rivals Surge Ahead
France is accelerating carbon capture deployment, but structural weaknesses in transport, storage capacity, and political clarity threaten to slow its path to carbon neutrality.

Making LAZY plants stand up: Research reveals new pathway plants use to detect gravity
A study by researchers at the University of Wisconsin–Madison has revealed a previously unknown pathway plants use to detect gravity and orient the direction they grow in. Publishing in Proceedings of the National Academy of Sciences, the study may one day open the door for improvements in crop cultivation.
