The new and final quarterly issue of DSWeb is now available: dsweb.siam.org Sorry, folks. DSWeb has had a good run.

Scientific breakthroughs often begin not with answers, but with imagination. During #SpaceScienceWeek, join singer Jewel for a keynote public lecture on data, sound, and the work of imagination in science. 🗓 March 25, 7 pm ET Learn more and register: nationalacademies.org/projects/DEPS-…

Looking for funding to support your research-related travel? Are you a recent PhD student? The AMS-Simons Travel Grant program funds activities that facilitate research interaction and collaboration in mathematics for recent PhD recipients. Dr. Ying Zhang, a recent AMS-Simons Travel Grant recipient, had this to say about her experience, "The support provided by the grant enabled me to attend key conferences and workshops that were pivotal for my professional development. These opportunities allowed me to present my work, receive valuable feedback, and build meaningful connections with researchers in my field. The application and reimbursement processes were straightforward and well-managed, which made the experience smooth and stress-free. I’m truly grateful for the program’s support and the impact it has had on my growth as a mathematician.” Learn more. Appy today. Link in comments.

A new theory of rapid behavioral inferences enables observers to leverage statistical regularities under strong time constraints — and can be applied to improve escape performance and capture features of escape behavior in fruit flies. 🔗 go.aps.org/4siVFs8

The @abel_prize 2026 has been awarded to Gerd Faltings! Woohoo! He received the prize for bringing together number theory and geometry to understand solutions to equations. Find out more here: plus.maths.org/abel-2026 #maths #math #mathematics

Last Saturday, over 8.5K people showed up to the @bklynlibrary for "Night in the Library: The Philosophy of Mathematics," part of our Infinite Sums #PiDay celebrations. Attendees wrote their own pi-kus, heard from legendary filmmaker Werner Herzog, and attended talks on #math from our @FlatironInst researchers.

Isaac Harris, @LifeAtPurdue, will give an Invited Address titled, "Qualitative Methods Applied to Biharmonic Scattering," at the 2026 Spring Central Sectional Meeting. Don't miss this or any of the special sessions, April 18-19, at @ndsu. Link in comments.

“Near the beginning of my career, I got the Fields Medal. And near the end, I’m getting the Abel Prize,” Faltings says. “It’s a nice duality.” scientificamerican.com/article/gerd-f…

Today, at the @DARPA expMath kickoff, we launched 𝗢𝗽𝗲𝗻𝗚𝗮𝘂𝘀𝘀, an open source and state of the art autoformalization agent harness for developers and practitioners to accelerate progress at the frontier. It is stronger, faster, and more cost-efficient than off-the-shelf alternatives. On FormalQualBench, running with a 4-hour timeout, it beats @HarmonicMath's Aristotle agent with no time limit. Users of OpenGauss can interact with it as much or as little as they want, can easily manage many subagents working in parallel, and can extend / modify / introspect OpenGauss because it is permissively open-source. OpenGauss was developed in close collaboration with maintainers of leading open-source AI tooling for Lean. Read the report and try it out:
