Building in zero gravity? ✅ Autonomously? ✅ With simple engineering principles? ✅ Our NOM4D program, with @Caltech, has demonstrated the first automated assembly of a structure in space, marking a major milestone in how we design, build, and operate beyond Earth.

It was an honor to celebrate @NASAJPL’s 90th anniversary and the inauguration of Caltech’s new president, Dr. Ray Jayawardhana!

For nine decades, Caltech has led JPL to become NASA’s premier center for deep space robotics, and together they are responsible for some of humanity’s most incredible achievements. I look forward to Dr. Jayawardhana's continued leadership and to many more JPL-led triumphs for science and for America.

Here’s a look at the hard problems these five universities are tackling: @Caltech: Expanding our partnership with Caltech to test whether large language models can accelerate innovative research in mathematics and physical sciences – pushing the boundaries of what AI can do in rigorous scientific domains @OhioStateMed: Developing AI workflows to assist radiologists screening X-rays, building AI tools for earlier heart failure detection, and building clinician-guided AI tools for Alzheimer’s diagnosis. @LSU: Implementing AI to improve non-contact infant tracheostomy monitoring, neurosurgical outcomes, VR training for medical professionals, and more. @IndianaUniv: Applying open-weight models to improve maternal-newborn care and learning, with a focus on tools that work with limited connectivity and accommodate diverse cognitive needs. @UTHealthHouston: Using Muse Glimmer, one of our smallest open-weight models, to support projects that improve treatment for brain cancer and agentic benchmarking in healthcare settings.

so excited for this!! huge thanks @AIatMeta, can't wait to dig into the Muse models with @AnimaAnandkumar at @Caltech and the meta team! I've already been using Muse Spark Open a lot through Open Math OS from @SAIRfoundation, and they've helped me catch some real issues in some of our libraries! Congrats to the other teams as well!!

SkAI and NNCI welcomed @Caltech’s Dr. @AnimaAnandkumar on neural operators & AI for science. From a weather model that beat supercomputers to simulating black holes and fusion reactors, she still emphasizes the human role: "AI isn’t replacing scientists anytime soon."
