How biological motors achieve maximum efficiency https://t.co/JME6UZl747 via @physorg_com
phys.org
Inside nearly every cell of your body, the tiny F1 motor works non-stop to create adenosine triphosphate (ATP), the universal energy source that powers almost every action you take—from breathing to...

Check out our recent work showing how environmental fluctuations let biodiversity beat the resource count, with peak diversity at intermediate competition. @_dzanc @SamirSuweis @DFAUnipd @LIPh_Lab @AvHStiftung @tuberlin.bsky.social
A path-integral solution of consumer-resource models shows that #SpeciesDiversity peaks when competitors moderately outnumber resources but collapses when they far exceed them, echoing #biodiversity patterns in real #ecosystems. Read the paper: https://t.co/kr51072xwi

Do ant colonies work like liquid brains? Check this great paper in @pnas, led by @ceabcsic Pol Fernandez-Lopez and @fredbartu, explaining foraging behaviour by modelling ants as mobile neural agents @JordiPinero

I’ve always been interested in the stories behind BioNumbers. Textbooks say DNA polymerase, for example, replicates 220 nucleotides per second. But how do we know this? How can one actually measure the speed of a single enzyme? A fast typist, for comparison, types ~80 words per

Now out in @AnnualReviews of Physical Chemistry: @DavidASivak and I review recent work studying flows of free energy into, out of, and within molecular machines. These nanoscale protein machines convert energy within cells of all living organisms with remarkable efficiencies.

Our article on Stochastic Resetting, in collaboration with @arnab_non_eqm (@IMScChennai ) and A. Kundu (@ictstifr), has been selected in the JSTAT 20th Anniversary Retrospective collection. @IOPscience #Physics. @LIPh_Lab @DFAUnipd
JSTAT, on its 20th anniversary, has published a spl issue showcasing influential articles since their inception. Our work on Resetting was selected as one of them, moment to cherish. Here's the entire collection: https://t.co/UvOcsbxCri

Akihiro's paper on ATP synthesis of V-ATPase has been published online in @jbiolchem! We verified that V-ATPase, which functions as active ion pump in the cell, has intrinsic functional reversibility and high thermodynamic efficiency of energy conversion! https://t.co/Iizlw9UD3x
jbc.org
V-ATPases generally function as ion pumps driven by ATP hydrolysis in the cell, but their capability of ATP synthesis remains largely unexplored. Here we show ATP synthesis of Na+-transporting...

Check out our latest research! We apply the framework of annealed disorder to ecological modeling 👇
PREPRINT OUT 💡 We show how consumer-resource communities with colored-noise fluctuations violate the competitive exclusion principle and give rise to realistic ecological structures https://t.co/J5uK2IhjiI

Our 3-year #research journey has culminated in a #publication in @softmatter, "Dynamics of switching processes: general results and applications to intermittent active motion," is now out. Grateful to co-authors @KristianSOlsen @ionfeeldcharge #Physics
https://t.co/hlMuwHYHfF
pubs.rsc.org
Systems switching between different dynamical phases is a ubiquitous phenomenon. The general understanding of such a process is limited. To this end, we present a general expression that captures...

Why are there so many fitness metrics in microbial ecology? I was confused - with @Michael_Manhart , I developed a framework that unifies existing statistics of relative fitness and shows how they all derive from a few basic principles. Preprint is up!

Much-awaited work on the cost of finite-time stochastic reset is now published in the @PhysRevResearch! 🎉 Fantastic collaboration with @KristianSOlsen (@HHU_de), @frnc_mori (@OxfordPhysics), and SupriyaK (@Stockholm_Uni). @SoftNordita #physicsresearch
journals.aps.org
Recent experiments have implemented resetting by means of an external trap, whereby a system relaxes to the minimum of the trap and is reset in a finite time. In this work, we set up and analyze the...

💡Research from the lab was just published in Physical Review Letters! Our own Sandro Azaele and Amos Maritan study non-Gaussian disorder in dynamical systems, with applications to ecological modelling:
journals.aps.org
We present a generalized dynamical mean field theory for studying the effects of non-Gaussian quenched noise in a general set of dynamical systems. We apply the framework to the generalized Lotka-V...
