Everybody in the "climate space" (which means everyone on earth...) needs to understand these mind-blowing figures. Google's "total electricity consumption jumped from 31 terawatt hours (TWh) in 2024 to 43 TWh in 2025." In ONE year. The AI corporate arms race is eating the world.

NEW BLOG FOR YOU Google's energy consumption numbers in their new climate report are mind-blowing. 2 years ago they flipped from linear to exponential growth, and their climate impact is blowing out, too. A WILD testament to the obscene bloat and waste of GenAI: ketanjoshi.co/2026/07/01/g...

Our new preprint is out!! The human brain runs on ~20 watts. Computers and modern AI systems require vastly higher energy. This gap raises a fundamental question: how does the brain compute so efficiently? In our new study, we take a critical step toward measuring and understanding this directly 1/3

Where do therapeutics go in the body? SCP-Nano combines whole-body imaging and AI to map nanocarrier biodistribution at single-cell resolution, revealing both intended targets and unexpected off-target destinations. Our recent work at @nature.com Biotechnology: www.nature.com/articles/s41...

I didn’t expect a short video about an octopus to stay with me this long. At first, it looks like a simple, almost playful interaction. But the more you watch, the more something deeper emerges: a learning process unfolding between two completely different forms of intelligence. 🧵 1/

How does blood flow relate to brain activity? We discovered that it reflects two neural populations affected oppositely by arousal. Together, they explain neurovascular coupling in all brain regions and brain states! Out today in Nature: rdcu.be/fdC2A @uclbrainscience.bsky.social

fMRI signals “up,” but neural metabolism might be going “down.” In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes. rdcu.be/eUPO8 funds @erc.europa.eu #neuroskyence 🧵:
