Evolution of Deep Learning by Hand ✍️ As my tribute to Geoff Hinton's Nobel Prize, I drew this animation to illustrate the key idea behind Hinton's major contributions to deep learning over the years, with artistic liberty. ---- 100% original, made by hand ✍️ Join 40k readers…
BIG ANNOUNCEMENT📣: I haven’t been this excited to be part of something new in 15 years… Thrilled to reveal the passion project I’ve been working on for the past year and a half!🙀🥳 It started from my frustration with the depressing effect that the current publishing system has…
Introducing NotebookLM for arXiv papers 🚀 Transform dense AI research into an engaging conversation With context across thousands of related papers, it captures motivations, draws connections to SOTA, and explains key insights like a professor who's read the entire field
Potassium isn’t just another mineral; it’s the body’s electrical currency. Understanding potassium balance why It matters for every cell: Potassium (K⁺) is one of the body’s most critical electrolytes. It drives nerve impulses, muscle contractions, and heart rhythm stability.…
NN-SVG: Create neural network architecture drawings parametrically! Export them to SVG files and use them in your work!
How does energy keep us alive? Our bodies are resistive energetic circuits where electrons flow from food→oxygen in our mitochondria. It's only through energy resistance (éR) - like electrical resistance - that transformation of energy into life is possible. The Energy…
Nobel Prize for Martini !! Finally !! Well deserved of course. Oh shoot ... Martinis ...
BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2025 #NobelPrize in Physics to John Clarke, Michel H. Devoret and John M. Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.”
I love watching women tear apart the most powerful mightiest egocentric people by just plain words. ❤️ Revolutionary women who stand up for humanity across the world are the most beautiful ones❤️❤️
You can teach a Transformer to execute a simple algorithm if you provide the exact step by step algorithm during training via CoT tokens. This is interesting, but the point of machine learning should be to *find* the algorithm during training, from input/output pairs only -- not…
A beautiful paper from MIT+Harvard+ @GoogleDeepMind 👏 Explains why Transformers miss multi digit multiplication and shows a simple bias that fixes it. The researchers trained two small Transformer models on 4-digit-by-4-digit multiplication. One used a special training method…
Using precise spatial and temporal analysis, researchers in Science provide insight into how bacteria around the root interact both with the plant and with each other. Learn more in this week's issue: scim.ag/3IFu3ws
Rest in peace Jane Goodall, a true giant among scientists. Your breakthroughs into the secret lives of chimpanzees viewed through an anthropomorphic lens – without yet knowing that science had forbidden it – changed science forever, and with it how we see ourselves.
biologists continue to mistake single-cell technical sampling noise for meaningful cellular heterogeneity. the apparent sparsity of single-cell data is due largely to technical artifacts like transcript capture and sequencing depth--if there are hundreds of thousands of…
"Only ~0.02%-3.1% of [a cell's] genome" is being transcribed at any given moment. Other interesting takeaways from this new paper: > If you pool together a bunch of cells of the SAME type (like primary immune cells from a mouse's spleen), and you measure the transcription for…

Last week, China barred its major tech companies from buying Nvidia chips. This move received only modest attention in the media, but has implications beyond what’s widely appreciated. Specifically, it signals that China has progressed sufficiently in semiconductors to break away…
I was on H1B too when I was a postdoc fellow at Harvard inventing spatial omics technologies. The US is about to lose its ability to attract a major chunk of the world’s top young talents in STEM innovations and hand over their strengths and competitiveness to other countries.
I was on a H1B visa for part of my postdoc. Also when I started as Assistant Professor. Several of my postdocs where on H1Bs. This new fee will affect more academia than tech or finance companies because there is no way universities can pay that… nytimes.com/2025/09/19/us/…
To all who are saying that the H1B Visa tariff is a blessing in disguise…I have just one question, why are all the blessings we get disguised & not just direct blessings…
“How” we sleep? “Why” we sleep? Open Access cell.com/neuron/fulltex…
The how and why of sleep: Motor theory and catecholamine hypothesis. The motor theory offers a unifying framework for sleep control, while the catecholamine hypothesis posits a core mechanism mediating sleep’s multifaceted benefits. Open Access cell.com/neuron/fulltex…
A friendly reminder that the Central Dogma is NOT "DNA -> RNA -> protein." All that Francis Crick *actually* said was: “Once information has got into a protein it can’t get out again.” This negative statement — namely, that some transfers of information seem to be impossible —…
A remarkably clear illustration of AI limitations: AI models minimize root-mean-square deviation but may produce physically implausible molecular structures. Classical docking tools outperformed AI methods.
