Open science tools like Simularium help bring science to life.

@mejohnson81 shares how it has helped her stoke curiosity in @JohnsHopkins students and work with colleagues across timezones.

My PhD work is online! Huge thanks to my advisors Carl and TJ, and collaborators! @taekjip @maryamyamadi @FuYiben @Mejohnson81

Does protein dimerization always help targeting and dwell time on DNA? Not for a population! Spacing between DNA targets has big impact. Nonspecific binding and facilitated (1D) diffusion play a key role. Super proud of Mankun Sang’s work!

Can sensing of membrane receptors be switched on at tunable threshold densities, without active processing? Proud to share this preprint led by the awesome Dr Foley, please check it out!

[Sam Foley @PhysFoley]

I’m excited to finally share our new preprint! Membrane-associated assembly processes like CME function as precisely-tunable, spatially targetable, robust on/off switches that don’t require energy at decision-time.

I am thrilled to have the opportunity to serve the @BiophysicalSoc in this role. The society has been so important and impactful for me and my #science over the arc of my career, and I am delighted to give back.

[Brian Camley @diffusiveblob]

Congratulations to @KarenFlemingPhD of JHU Biohysics, president-elect of the Biophysical Society! Very exciting!!

[Rommie Amaro @RommieAmaro]

Please nominate one of your amazing junior or mid career colleagues for the @BiophysicalSoc Theory & Computation Subgroup Award

They'll receive a cash prize & speak at the 2025 annual meeting in sunny Los Angeles☀️🌴

[Fred Meunier @MeunierLab]

Very excited to share our Jeff (Anmin) PhD paper in collaboration with @Mejohnson81 and Phil Robinson demonstrating that Dynamin 1 undergo Dimensional Reduction: (1) recruitment to the membrane and (2) clustering, to make endocytosis happen.

Alternate paper title: "Unsupervised machine learning discovers optimal pathways of self-assembly" @murugan_chicago

[Margaret Johnson @Mejohnson81]

Excited to share our latest paper: no matter how stable the macromolecular assembly, kinetic traps can always be avoided by exploiting nonequilibrium protocols. awesome effort by Adip Jhaveri and former undergrads Spencer and Yian! https://t.co/8l964XdzVj

[Margaret Johnson @Mejohnson81]

Having diverse subunits in the complex helps expand the solution space. Automatic differentiation is a super cool method for optimization in large parameter spaces, thanks Spencer!

[Margaret Johnson @Mejohnson81]

@Nicolas_Fawzi @TheLHSeries thanks Nick! You may not remember but you were the one who I asked about the methyl group and who was, perhaps reasonably, appalled.

Want to work on biological physics at Johns Hopkins? (OK, or other areas of physics which I accept are also interesting). We have a prize postdoctoral fellowship, with competitive pay, some independent research budget - Dec. 1 deadline https://t.co/UjCbKghhc3

[Karen Fleming @KarenFlemingPhD]

Our faculty search is still open for 10 more days. Come join our biophysics department.

[Taekjip Ha @taekjip]

The 2024 Biophysical Society meeting will be in Philadelphia. The abstract deadline is just about two weeks away. We have the BPS Lecture by @CarolynBertozzi and an exciting program by @TheVillaLab and Ibrahim Cisse. And the dance is back!

[Margaret Johnson @Mejohnson81]

Excited to share our preprint where we 'discover' kinetic protocols for macromolecular self-assembly of highly stable complexes https://t.co/pxgumViSK5
Awesome grad student Adip Jhaveri and former undergrad Spencer Loggia, automatic differentiation is a cool method!

[Margaret Johnson @Mejohnson81]

Johns Hopkins Biophysics is hiring tenure-track faculty as part of a faculty expansion at JHU! All ranks, all areas molecular to cellular, theory, comp. and experiment.

[Brian Camley @diffusiveblob]

One of my departments is hiring - Hopkins is a great place to work, and I'm happy to answer questions: https://t.co/0vYEIrUq2f

[Margaret Johnson @Mejohnson81]

@Qi_Xieqi @sikao14 it was great working with you!
