JAXA engineers released terrestrial hop-test compaction curves tied to SLIM’s LEV-1 leaps, showing how Shioli regolith density spikes under repeated 40-centimeter hops.
JAMSTEC published deep-trench methane flux readings off the Oshika Peninsula from a submersible cruise, showing seasonal seeps higher than 2011 baseline models but below levels that would rewrite nearshore fishing carbon budgets without multi-year repeats.
A University of Tokyo–led cruise mapped Kuroshio mesoscale whirlpools off Shikoku, feeding tsunami debris dispersal models that Japan’s meteorological agency will test against 2011 drift card archives.
RIKEN CSRS researchers cataloged polyesterase genes from abyssal sediment microbes, offering feedstock hints for marine-biodegradable plastics NEDO wants scaled before 2028.
JAXA scientists reported hydroxyl-rich signals in Hayabusa2 Ryugu grains during follow-on synchrotron work, tightening models of how water reached early Earth without a monolithic ice comet.
Nikkei Friday 64,011.34 still last. Chunichi won 1-0 in eleven. Monday 9:00 JST has not opened.
