🤖🌌 Researchers in #Japan developed the first #galaxy simulation tracking over 100 billion individual #stars by combining #AI with traditional #physics models, completing in 115 days what would normally take 36 years.

Researchers combined deep learning with high-resolution physics to create the first Milky Way model that tracks over 100 billion stars individually. Their AI learned how gas behaves after supernovae, removing one of the biggest computational bottlenecks in galactic modeling. The result is a simulation hundreds of times faster than current methods.

Learning manipulable representations of the world and its dynamics is central to AI. Joint-Embedding Predictive Architectures (JEPAs) offer a promising blueprint, but lack of practical guidance and theory has led to ad-hoc R&D. We present a comprehensive theory of JEPAs and instantiate it in {\bf LeJEPA}, a lean, scalable, and theoretically grounded training objective. First, we identify the isotropic Gaussian as the optimal distribution that JEPAs' embeddings should follow to minimize downstream prediction risk. Second, we introduce a novel objective--{\bf Sketched Isotropic Gaussian Regularization} (SIGReg)--to constrain embeddings to reach that ideal distribution. Combining the JEPA predictive loss with SIGReg yields LeJEPA with numerous theoretical and practical benefits: (i) single trade-off hyperparameter, (ii) linear time and memory complexity, (iii) stability across hyper-parameters, architectures (ResNets, ViTs, ConvNets) and domains, (iv) heuristics-free, e.g., no stop-gradient, no teacher-student, no hyper-parameter schedulers, and (v) distributed training-friendly implementation requiring only $\approx$50 lines of code. Our empirical validation covers 10+ datasets, 60+ architectures, all with varying scales and domains. As an example, using imagenet-1k for pretraining and linear evaluation with frozen backbone, LeJEPA reaches 79\% with a ViT-H/14. We hope that the simplicity and theory-friendly ecosystem offered by LeJEPA will reestablish self-supervised pre-training as a core pillar of AI research (\href{git@github.com:rbalestr-lab/lejepa.git}{GitHub repo}).

We've all experienced those magical instances when complex problems become simple. The breakthrough that seemed impossible becomes obvious in retrospective analysis.
Share this with someone struggling through a difficult project phase. The solution is closer than they think.
Describe your most satisfying problem-solving moment. When did impossible suddenly become inevitable?

I was poisoned by #tetracycline in the 1960s when I was a kid. TBH, I don't know if I was poisoned if my #Mom took it while #pregnant with me, or if it was given to me after I was born. Regardless, I've spent my entire life with #rotten, #ugly, #brown #teeth (even my baby teeth!) because the #medicine stripped the #enamel off them. 😢
I hope this means that no child will ever have to endure what I have.
#Breakthrough gel can regenerate #tooth enamel within weeks

An innovative gel that forms a layer over teeth and then recruits calcium and phosphate ions from saliva to build new enamel has the potential to change dental treatment. To date, we don't have any way to regenerate the tough outer layer of enamel on our teeth as it erodes with age.
