Bio-ISRU: the microbes quietly rewriting the off-world supply chain
Bio-ISRU turns crew waste, local CO2 and regolith into food, plastics and propellant, cutting Mars base launch mass by up to 85%.

AI-Designed Catalysts Are Rewriting the Carbon Capture Playbook
For decades the carbon-capture bottleneck wasn’t the idea — it was the material. Generative AI now designs the sorbents and catalysts that decide whether direct air capture pays for itself.
CodeRabbit's $143M raise bets on the control layer for AI-written code
CodeRabbit's $143M Series C funds a new category, Agentic Change Management, the control layer that governs code from humans and agents alike. The bet is that review, not generation, becomes the scarce and defensible layer as coding agents flood teams with changes.
Katalyst Space bets NEXUS turns satellite servicing into infrastructure
A $12M round and a DIU award put Katalyst's NEXUS geostationary robot at the front of the race to make satellite servicing real infrastructure.
The Living Cathode: Engineered Microbes Turning CO2 Into Hydrogen
Microbial electrosynthesis uses living electroactive biofilms as biocatalysts that turn CO2 and renewable power into hydrogen. A 2026 breakthrough doubled acetate output by steering which microbe grows on the cathode, and startups Ossus and Cemvita now aim the same living cathode at fuel.
Human Tissue, Printed in Orbit: Auxilium’s ISS Milestone Reshapes Biomanufacturing
Auxilium’s AMP-1 printed the first kidney and liver tissue ever made in orbit, pointing to orbital biomanufacturing for organoids and implants.
Why the military, not utilities, is pulling small nuclear to market
The US military is becoming small nuclear's first real customer. With Antares' $470M raise, the Air Force's three-vendor ANPI program, and Project Pele's 2028 demo, defence is pulling small reactors to market ahead of utilities.
The HALEU bottleneck: one fuel line feeding the grid and cislunar rockets
One fuel line now serves two customers: advanced reactors on the grid and cislunar rockets. The bottleneck is enrichment and fuel fabrication, built years ahead of the reactors that burn it.
