We recently published an open source dataset of building footprints and height estimations for the Global South. It covers ~2 billion buildings and 8 years of data derived from Sentinel 2 imagery.

very elegant way to put it... "strong programming skills (even in cases where support from an LLM is not available)"

Kind of a big deal. We can now monitor and track air pollution by the hour. ESA Sentinel-4 can beam back hourly data on nitrogen dioxide hotspots & sulfur dioxide plumes. This is a massive leap for public health & air quality forecasting. See Northern Italy 😱

This image depicts tropospheric nitrogen dioxide with clear pollution hotspots visible along the Mediterranean coast and over Italy’s Po Valley.

This image shows a vertical column of ozone. While ozone high up in the stratosphere plays a crucial role in shielding life on Earth from harmful ultraviolet radiation, ozone in the lower atmosphere acts as a pollutant, contributing to poor air quality and respiratory problems.

This image presents a vertical column density of sulphur dioxide. A distinct plume can be seen emerging from Mount Etna in Italy and drifting south-eastwards over the sea. Although Etna is currently relatively calm, much larger plumes are typically observed during periods of heightened volcanic activity.

That's also my assumption. Btw congrats on the "for you" algo, it's so good!

moral of the story:
AI isn't always the answer
Necessity really is the mother of invention (i recommend reading the solution and the comments)
If you're GPU poor, don't count yourself out. Ingenuity can still win.

Competitor enters a major AI competition (RNA folding)
GPU poor so can't train an AI
Builds a "classic" eng pipeline instead. (90s tech)
Wins and beat everyone using DL 💀
Their winning "hybrid" model had an AI in it. Their original one did not and had a higher score
So they won despite the AI 😂

This is so cool. When you look at representational geometry, it seems intuitive that models are combining convex regions of "concepts", but I wouldn't have expected that this is PROVABLY true for attention or that there was such a rich theory for this kind of geometry.

I am recruiting PhD students to start in 2026! If you are interested in robustness, training dynamics, interpretability for scientific understanding, or the science of LLM analysis you should apply. BU is building a huge LLM analysis/interp group and you’ll be joining at the ground floor.

Naomi Saphra @nsaphra.bsky.social · Mar 27

Life update: I'm starting as faculty at Boston University
@bucds.bsky.social in 2026! BU has SCHEMES for LM interpretability & analysis, I couldn't be more pumped to join a burgeoning supergroup w/ @najoung.bsky.social @amuuueller.bsky.social. Looking for my first students, so apply and reach out!

Gemma 27B variant discovered a new cancer pathway treatment that has been validated

Scientists setup an environment and context, the model made a novel inference

blog.google/technology/a...

What made this prediction so exciting was that it was a novel idea. Although CK2 has been implicated in many cellular functions, including as a modulator of the immune system, inhibiting CK2 via silmitasertib has not been reported in the literature to explicitly enhance MHC-I expression or antigen presentation. This highlights that the model was generating a new, testable hypothesis, and not just repeating known facts.
