(1/2) The simplest models of dsDNA maps the double helix to a continuous rod/cylinder with twists and bends along the polymer. The groove asymmetry of DNA results in coupled twist-bend modes. Here we solve for the exact chain statistics and . .
When is DNA like an asymmetric top? Check out @AsheshGhosh1's study on the twisted worm-like chain, a good model for DNA mechanics, whose Green's function is solved in a basis of Wigner D-functions, the eigenfunctions of the asymmetric top @UCB_Chemistry

Excited to share this latest work on a crucial aspect of endosome tethering and fusion. The work shows how small scale changes can sometimes drive large scale coordinated transformations. Have a look at this work @
Ashesh Ghosh and Andy Spakowitz published “Local changes in protein filament properties drive large-scale membrane transformations involved in.endosome tethering and fusion” in Soft Matter. Excellent work, Ashesh!

(1) Can we say if active forces are at play by looking at polymer structure and/or single-/multi-point trajectories of polymers? .(2) If yes, which locations along the chain experience activity? How are they correlated?.@SayantanD2 answers these here 👇.
How does spatial and temporal correlation of active forces impact structure and dynamics of biopolymers? We adapt the physics of flexible polymers and demonstrate using an e.g. of point fluctuation in this work with @AsheshGhosh1 and @ASpakowitz now online in @softmatter (1/2).

Large scale biophysical changes are often driven by orchestrated events at much finer length and timescales. With @ASpakowitz we show how local filament properties drive large-scale membrane transformations. Preprint at

A friend's kid spent some time shadowing her mom in the lab and took some notes to write a story about cells. She shared the notes with me and told me all about 'what cells do in the lab?'.At the end of her observation window she says "lab is done".

This object is fascinating! Gabriel's horn, or, Torricelli's trumpet is essentially the surface of revolution of y=1/x around x-axis (from x=1 to infinity). While it has a finite volume (=pi), the surface area is infinite.

Accounting for many-body correlation is crucial to understand slow dynamics of supercooled liquids. This article elucidates the role of deGennes narrowing in collective Debye-Waller factors and glassy dynamics of model hard sphere fluids. @AsheshGhosh1.

Such a great feeling to listen to Prof. Jarzynski talk about "Scaling down the laws of thermodynamics". Tuning into stochastic and non-equilibrium thermodynamics is always fun!! 🙂

I remember studying about the periodic table of elements and evolution in 8-9th standard and really got exposed to what I thought as the two fundamental pillars of chemistry and biology. Shocking to read this news:.

May the 4th be with you!.Here is a paper on the "financial repercussions of the destruction of two fully armed and operational "Death Stars" in a 4-year period and the dissolution of the galactic government in Star Wars". 😀.

de Gennes narrowing (dGn) for complex fluids describes the characteristic slowing down of dynamics in the vicinity of cage coherence. Excited about the preprint on crucial role of dGn in a single particle theory of glassy dynamics.

Excited to share the last work in my PhD thesis on stress overshoot in dense colloidal suspensions with Ken Schweizer. We show how it's crucial to account for structural changes to properly capture the transient shear response. link:
