Scientists Built a Working Computer Memory Out of Shiitake Mushrooms
A computer that relies on fungal mycelium to store information could one day be a low-cost alternative to the current generation of memory hardware.

This weekend, I have been doing a bit of reading about Gaussian Process State Space Models (GP-SSMs). Aside from being interesting on the modelling and inference sides, they are a remarkably good exercise for what it really means to write down a joint distribution.

Can general artificial intelligence emerge by not following the evolution of complex brains? In this 2022 paper with @brigan.bsky.social we argued that embodiment, mind reading (mirror systems), mental time traveling... are necessary conditions

**Differentiable Generalized Sliced Wasserstein Plans**

@rtavenar.bsky.social

We propose a Generalized Sliced Wasserstein method that provides an approximated transport plan and which admits a differentiable approximation.

My fellow #FourierTransform enthusiasts, here's a new entry in my collection ready for you, nr. 56! The real-space picture is an intersection of two tilings of squares, one tilted by 43°. Moiré pattern? Definitely related 💯

As always, you can find the high-res pair at behance.net/specialdefects
A collection of bright yellow spots starts from the centre of the picture, from the strongest, central one. Clearly not periodically arranged, they have a point-symmetry evident since 4 equally spaced lines of stronger spots irradiate from the centre of the image. Between them, additional smaller spots form geometrical patterns vaguely resembling the fourier transform of an aperiodic crystal. The background colour alternate dark blue and soft teal, whose calm feeling contrasts the energy present in the bright yellow spots, looking like tiny fireflies.

Hooray, an excuse to go on and on about spin noise! Predicted correctly by Bloch in 1946
A clip of text: “Even in the absence of any orientation by an external magnetic field one can expect in a sample with N nuclei of magnetic moment u to find a resultant moment of the order sqrt(N)*\mu because of statistically incomplete cancellation. This moment, however, would naturally be very small and in samples of normal size will be greatly increased as soon as the nuclei have found their equilibrium distribution in a field of a few thousand Gauss which, at the same time, will bring their Larmor precession into the convenient radiofrequency range.”

In cellular automata, simple rules create elaborate structures. Now researchers are working backward — starting with the result to learn the rules behind it. @georgemusser.com, SFI’s 2025 Journalism Fellow, explores how this could reshape computation and self-organization in Quanta:

In August, an SFI working group explored the challenges and opportunities of digital-twin technology—virtual representations of physical objects, designed not as simple models but as complex systems that use real-time data to mirror their real-world counterparts.

I am very happy to finally share something I have been working on and off for the past year:

"The Information Dynamics of Generative Diffusion"

This paper connects entropy production, divergence of vector fields and spontaneous symmetry breaking

Extra nice paper giving an information theoretic perspective on diffusion models. Shows the generation process correspond to bifurcations with splits being decisions between different attractors.
I don't know if Luca Ambrogioni is on bsky to tell us more (I doubt it).
