What is the origin of diversity in allometric laws scaling across species? Check our new paper led by Andrea Tabi where
we propose a new theory of metabolic scaling grounded in thermodynamics and stochastic fluctuations at the cellular level.

In #drylands, plants don’t grow randomly — they self-organize into disordered hyperuniform patterns that help them use water wisely & endure extreme aridity. A beautiful hidden logic of nature, revealed in a new @pnas.org study doi.org/10.1073/pnas... including #Maestrelab alumni

Why is universality such a central concept in complex systems? How does it connect Turing Machines and Spin Systems? In this new paper, Tomáš Gonda and @gemmadlc.bsky.social present an accessible account on how to identify and compare different universalities arxiv.org/pdf/2406.16607

What do Pac-Man, Space Invaders, and Mortal Kombat have to teach us about #cultural #evolution? As a social-technological phenomenon, #arcade game genres evolved like cultural species—some diversified, while others became "living fossils." 🕹️🧪 👉 doi.org/10.1017/ehs....

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

Are there universal principles for the structural limits of living organisms? How can physics provide a theory? Check this @pnas.org paper that derives Kleiber’s law from 1st principles, capturing geometric differences and predicting life forms between plants & animals. www.pnas.org/doi/pdf/10.1...

For the record, there's no point inviting me to give any talks or attend any conferences in the US for the foreseeable future. Sorry, but it's really not worth the risk.

The company’s turbines — enough to power 280,000 homes — run without emission controls in an area that leads Tennessee in asthma hospitalizations.

How can biological systems anticipate future events? In our new paper with @jordiplam.bsky.social, we show how a simple genetic circuit can predict future trends through a simple (and perhaps widespread) mechanism @drmichaellevin.bsky.social @koseskalab.bsky.social www.biorxiv.org/content/10.1...

Why study simple mathematical models? "Because they invite improvement," says #NASmember Steven Strogatz in his #NAS162 Research Briefing, and they may suggest spinoffs in neuroscience, social psychology, machine learning, and more. Watch live: ow.ly/V02g50VImXZ

26 years before Watson, Crick & Franklin's DNA discoveries, a Russian scientist, Nicolai Koltsov, with great intuition, said that inheritance should be stored in double-stranded giant molecules using each strand as a template. Hats off. Check this: d1wqtxts1xzle7.cloudfront.net/80280764/lys...
