Artificial Intelligence (AI) - NSF Small Business Innovation Research (SBIR)/Small Business Technology Transfer (STTR) is sponsored by U.S. National Science Foundation (NSF). This program focuses on cutting-edge technologies in deep learning-based AI systems and AI-based hardware, emphasizing next-generation AI technologies that are safe, reliable, fair, robust, privacy-preserving, and efficient. It explicitly includes Computer Vision Based AI Technologies. Small businesses can receive non-dilutive funding for high-risk, high-impact technologies with strong commercial potential.
NSF 26-516 folds Atmospheric and Geospace Sciences, Earth Sciences and Ocean Sciences into a single GEO Core solicitation: $110 million, 200 to 350 awards, proposals accepted anytime. Geosciences piloted no-deadline review nine years ago and knows what it does to submission volume. Here is the per-award math, the ship-time and permitting traps, and the two-year data-archive clock that now governs every award.
Read articleNSF 26-520 consolidates 14 mathematical sciences programs into $200 million and 400 to 600 awards with no per-PI cap and no deadline. Folded into it are Research Training Groups and Focused Research Groups — department-scale, cohort-building competitions that ran on a fixed annual date. Here is why removing that date is a different kind of change for training grants than for single-investigator grants, and what math departments should do before the fall.
Read articleNSF 26-522 consolidates AAG, ATI and MSIP into a single astronomical sciences solicitation with $100 million and about 140 awards. Accomplishment-based renewals will be returned without review, voluntary cost sharing is prohibited, and routine instrument upgrades are explicitly deprioritized. The new Innovations track — one to three awards a year — is where facility operations and community observing time now live.
