Three years after a team of Caltech scientists showed that pairs of entangled photons could double the resolution of a light microscope, the same lab has figured out a way to double down on that improvement. caltech.edu/about/news/new…
At California Institute of Technology, a little-known band of admissions officials is scrutinizing the fonts on science-fair certificates, checking addresses on high-school transcripts and analyzing signatures on awards. 🔗: on.wsj.com/3Tx1HJT
Interstellar travel may be one step closer. Researchers from @MEAM_Penn, @Penn_ESE, @Caltech and @UCLAengineering developed an ultra-thin light sail that could propel spacecraft using lasers. The breakthrough brings laser-driven space travel one step closer to reality. “Years ago, we were asking what these sails should look like,” says Igor Bargatin, Associate Professor in MEAM. “Now we’re actually building them.” bit.ly/4vThFLD
New research from Caltech analyzing pieces of a meteorite has found that, the same way that snowflakes crystallize around grains of dust, ancient stardust grains leftover from long-gone suns may have been the seeds of our solar system's earliest solids. caltech.edu/about/news/anc…
Since 2018, @ztfsurvey has observed more than 80 black holes via cosmic events known as TDEs. Mostly spotted at the center of galaxies, #UMD astronomers & ZTF partners have now discovered a supermassive black hole far away on the outskirts. ztf.caltech.edu/new/ztf-spots-… @UMDscience
Using NASA's James Webb Space Telescope (JWST), a team of Caltech researchers has observed Neptune's rings and three of those moons—Larissa, Galatea, and Proteus—and found that their composition is unique among outer solar system bodies. caltech.edu/about/news/nep…
Researchers at Caltech and Google have uncovered important new insights about how clouds might respond to warming sea-surface temperatures and rising CO2 levels using a large and powerful dataset of simulations developed by the group. caltech.edu/about/news/low…

Two new multi-institution collaborations led by Caltech scientists have been selected to receive first-round funding from the U.S. Department of Energy (DOE) as part of the Genesis Mission, a national effort to use AI to accelerate scientific discovery. caltech.edu/about/news/two…
What is life like aboard a research ship? For Allen Husker and his students, most days were spent working on theses and papers, but there was still time for fun! They watched movies, turned the mess hall into their own impromptu coffee shop, played games, and tested their table tennis skills against the movement of the ocean! Beautiful sunrises and sunsets together rounded out life at sea. Read more about the expedition: husker.sites.caltech.edu/research/magne…
What was once only visible from a distance, we could now reach out and grasp… Throughout history, humanity dreamed of Mars – but it was never within reach. That changed 50 years ago when NASA's Viking 1 lander touched down on the surface of the Red Planet on July 20, 1976.
Nobel laureate Rudy Marcus, Caltech's John G. Kirkwood and Arthur A. Noyes Professor of Chemistry, passed away on July 16, 2026. The prolific chemist was five days shy of his 103rd birthday. caltech.edu/about/news/cal…

Each year, the National Science Foundation selects students to receive Graduate Research Fellowships that fund three years of graduate study. This year, 33 Caltech alumni and 19 graduate students have received these fellowships. caltech.edu/about/news/nsf…
Excited to share our @icmlconf paper: M+Adam: Low-Precision Training via Additive–Multiplicative Optimization We introduce M+Adam, an optimizer that combines Adam-style additive updates with Madam-style multiplicative updates to enable more effective optimization of low-precision master weights. Modern training already uses BF16, FP8, and FP4 arithmetic, but typically retains higher precision master weights so that small optimizer updates are not lost. We instead study optimization directly on BF16, FP8, and NVFP4 master weights, where the optimizer must operate under the constraints of the low-precision floating-point grid. Additive and multiplicative updates have complementary strengths. Additive updates naturally handle small weights, exact zeros, and sign changes. Multiplicative updates remain effective at large magnitudes, where additive updates can be rounded away. Paper: arxiv.org/abs/2607.10611 Code: github.com/Anima-Lab/M-Ad… @SLoeschcke @Caltech
