Two DNA double helices were directly imaged zipping together for the first time, confirming a more than 20-year-old model. The pairing was precise, groove for groove, but some sequences formed stronger hotspots.

Decades-old DNA mystery solved after strands are captured zipping together for the first time
Researchers have captured the moment two DNA molecules zip together, overcoming their identical negative charges to pair up and revealing a mechanism that has puzzled scientists for more than 20 years.

How DNA strands meet to divvy up chromosomes was a longtime mystery. www.sciencenews.org/article/dna-zip…

See the secret to DNA hookups
A record player-like microscope and computer simulations solve a longtime mystery, showing that metal ions bridge DNA strands that would normally repel.

How do DNA duplexes recognize and pair with each other? Thomas Catley, Victor Velasco Berrelleza, @alicepyne.bsky.social and myself present the first direct visualization of DNA-DNA pairing mediated by divalent cations, confirming the decade-old DNA zipper model! doi.org/10.1093/nar/...

Is gene regulation only dictated by biochemistry, or are we missing the bigger physical picture? 🧬✍️ Find our latest review article with Sarah A. Harris and Wilma K. Olson in Current Opinion in Structural Biology, where we advocate for "Physical Genomics” doi.org/10.1016/j.sb...

Supercoiling not only brings DNA to life (and makes it dance) but also changes how key proteins such as #CRISPR interact with it. Thanks @qmsmith.bsky.social for the brilliant collaboration, Sylvia for developing an amazing new #imageanalysis pipeline & @eddierollins.bsky.social for beautiful #AFM.

Were you interested in our last paper published in Phys. Rev. Lett. (with Matthew Burman at the University of York) but found it too hard to follow? Then, look at the piece from @sciencex.bsky.social where it is explained in more plain terms with the help of Ingrid Fadelli

Our last paper just appeared in Physical Review Letters. We studied how linear DNA is distorted by torsion and tension using all-atom simulations. Excellent work from Matthew Burman's EPSRC-funded PhD. Thanks to N8 CIR and HecBiosim for computational resources doi.org/10.1103/Phys... See thread 👇
