With more than 400,000 homes destroyed in the war, Gazans are being forced to choose between living in tents exposed to the elements or run the risk of living inside the ruins of buildings that could collapse any minute. https://cnn.it/4qfJrj4

Are bacterial spores some kind of travelling neurons? In this @science.org paper the authors show that B. subtilis spores can integrate environmental signals over time and remember transient nutrient pulses. @koseskalab.bsky.social @drmichaellevin.bsky.social www.kaitokikuchi.com/assets/pdf/K...

How did organs originated in the evolution of multicellularity? Despite their obvious importance, we still lack a theory of evolutionary organogenesis.

A balance of infection and harmony called endosymbiosis helps shape evolution. For the first time, biologists have reproduced this arrangement between microbes in a lab.

What if the human brain computes quantum-like, without being quantum? New work by @melisupf.bsky.social Gus Deco shows that whole-brain models with quantum-like (QL) probability rules best match human brain data. @manlius.bsky.social @icreacommunity.bsky.social www.biorxiv.org/content/10.1...

What would happen to consciousness if two brains were connected? Could two people share experiences while remaining distinct selves? Cases like the Hogan twins suggest yes, and theories about the neural locality of consciousness make shared experience likely. philarchive.org/archive/COCA...

Classical billiards can compute. With Isaac Ramos, we show that 2D billiard systems are Turing complete, implying the existence of undecidable trajectories in physically natural models from hard-sphere gases to celestial mechanics. Determinism ≠ predictability. 🎱🧠 @upc.edu @ricardsole.bsky.social

🚨 What if evolution is the ”law”… and networks are the machines that do the work? In this paper (just published) I try to formalize how living systems are non-equilibrium, information-processing, adaptive matter. With a great biological flavor! 🧪🌐🌍🧬🦠 👉 iopscience.iop.org/article/10.1... 🧵 1/

“Those of us who do not believe that we are divinely created, let alone divinely supervised, are not immune to the idea of awe and beauty and the transcendent.” Christopher Hitchens gave a powerful defense of awe in science. He died 14 years ago today. www.youtube.com/watch?v=2K0a...

Can design principles be defined for #biocomputation beyond living circuits or standard engineering approaches? Yes. We identified an alternative route based on a class of distributed computation enabling combinatorial design for #synbio link.springer.com/article/10.1...

It's been thought since the early 70s that eukaryotes (basically any life with a cell nucleus) wouldn't survive above 62C and no complex life had been shown living above 60C. Until the "fire amoeba"... 🧪 (These are some of my favorite stories to write, just weird neat stuff we're learning.)

Can ecological network theory explain the transition from health to disease in microbiome-related processes? Yes, and this outstanding new paper led by Miguel A. Muñoz shows exactly how. An exceptional contribution that moves the field forward: www.biorxiv.org/content/10.1... @vmaull.bsky.social

TIL about a memorial ceremony in Iceland in 2019 to mark the end of a glacier, changing the place name from Okjökull to Ok (jökull = glacier). Uncompromising wording on the bronze plaque: "This is to acknowledge that we know what is happening and what needs to be done. Only you know if we did it".

Could cognition emerge from matter at scales far below neurons? This @nature.com paper explores whether molecular self-assembly can perform neural-like classification. The work suggests that even physical processes may carry out sophisticated information processing. www.nature.com/articles/s41...

A new special issue of Philosophical Transactions B takes on one of science’s biggest questions: how life begins. Rather than retracing Earth’s history, the authors look for the universal conditions that could make life possible anywhere, approaching the question from many fields and angles.

So after listening to multiple talks by philosophers of mind who defend consciousness as the substrate of the entire universe, and physicists who invoke quantum mechanics as the source of consciousness, the conclusion is clear: they have no idea about neuroscience, nor any interest to know about it.

Why do cultural skills (reading, maths) consistently activate the same brain regions across people? @standehaene.bsky.social and L. Cohen argue that culture doesn’t create new brain circuits: it invades evolutionarily ancient maps of the cortex. check this great paper www.cell.com/action/showP...

Why do some cancers respond to immunotherapy while others don’t? A new paper by @guimaguade.bsky.social shows, using maths, that as tumors mutate, they face a trade-off: growing faster can also make them easier for the immune system to spot. @sandyanderson.bsky.social www.biorxiv.org/content/10.1...

In a sense, yes: at the molecular–cellular level, death is the failure of energy-driven mechanisms that maintain vital gradients. Yet other forms of death—like that of the mind—need not involve this physical breakdown.

What is the physical basis of death? Can we manipulate cellular rules to avoid it? What does death mean for a machine? Is immortality possible? What does it mean for language, thought, or information to die? My new book @princetonupress.bsky.social is coming soon. press.princeton.edu/books/hardco...
