Where is the information in your NMR FID? u-of-o-nmr-facility.blogspot.com/2015/04/the-... #nmr #nmrchat #chemsky
Literally the coolest thing I’ve seen all year. And not from the group I expected!

The 22nd issue of the Artificial Life Newsletter is out! 🐛
This edition was a print edition, in tandem with #ALIFE2025 last week in Kyoto.
Enjoy learning about the laziest form of life and origami robots in this edition! 📚

Removing t1 noise from homonuclear 2D NMR data - video tutorial. youtu.be/XhmzjxkPouo?... #nmr #nmrchat #chemsky
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.
A tiktok for cellular automata rules!
This project was developed during the #ALife2025 hackathon (can you believe how fast people make things?) and won the hackathon prize!

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

Super cool. Reminds me of the NeuralODE paper that motivates them as infinite-depth ResNets.
Now accepted at #NeurIPS2025 :)
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.
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 💯

Cool.

FT NMR spectra without RF pulses u-of-o-nmr-facility.blogspot.com/2011/04/ft-n... #nmr #nmrchat #chemsky
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.

Postdoc job! I expect to have an opening at Johns Hopkins for a postdoctoral researcher working somewhere in the broad realms of physics, philosophy, and complexity. Apply at Academic Jobs Online:

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
link: arxiv.org/abs/2508.19897
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).

You have 2 days left to apply to become a member of the board of the International Society for Artificial Life!
If you have ideas/complaints about the interface between ISAL and the ALife community, this is the time to make yourself heard!

What is emergence? This is one of the most central ingredients of complexity, and a challenging one to formalize. Here's a paper by @seanmcarroll.bsky.social & Achyth Parola that attempts to classify different forms of emergence. @manlius.bsky.social @sfiscience.bsky.social arxiv.org/pdf/2410.15468
Do ant colonies work like liquid brains? Check this great paper in @pnas.org led by @ceabcsic.bsky.social Pol Fernandez and F.Bartumeus that shows how to explain collective foraging by modelling ants as neural agents @jordipinero.bsky.social @frazambelli.bsky.social www.pnas.org/doi/10.1073/...
How to deal with the multiscale nature of evolution, which displays different time scales of change? We need to replace classic genotype spaces with multiscapes. Here's a great paper by my friend Susanna Manrubia and coworkers @mncn-csic.bsky.social rsob.royalsocietypublishing.org/content/royo... …

It's fun to publish something 20 years ago which refutes a recently published proof of P ≠ NP
