A theoretical framework for random acceleration molecular dynamics simulations The dissociation of a ligand bound to a receptor is a rare event occurring on a timescale that is far longer than can be afforded by standard simulation methodo

We developed a simple theory and showed that Random Acceleration Molecular Dynamics (RAMD) is consistent with a Smoluchowski equation with an effective temperature and diffusion coefficient that depend quadratically on the magnitude of the random force.

Congratulations Roland!

scientists: be honest, how often do you take a day off for the beach and call it pier review

I can remember seeing Dick Allen at Connie Mack Stadium in Philly swing at a pitch over his head and drive into the outfield for a nice hit. He was incredible.

picture of a TV screen hanging in a hallway, the TV screen shows slide which reads "Herzlich willkommen im Chemischen Laboratorium, Inaugural Lecture (GDCH), Fiona Kearns University of Freiburg 'Emerging opportunities in Biophysics: Glycoprotein Characterization by Simulation'" with a picture of a woman, The slide also indicates the date (Dec 15, 2025), time (5:15) and location (Horsaal Chemie) for the lecture

Are you from @uni-freiburg.de? wanna come see me talk about my research on Dec 15 at 5:15 in the main Chemie Horsaal?

Nope, we ain’t. It was a really enjoyable day. Thank you.

Excited to share a new update to the Drude polarizable force field - phosphorylated amino acids! A long-term project that took quite a bit of effort. Great work with PhD student Laura Gil Pineda, former undergrad Candace Miller, and @alexmackerell.bsky.social

We enjoyed your visit to Univ Maryland Baltimore and great to spend time with a colleague with whom I shared an office 35 years ago! Ain't dead yet...

And certainly don't ask generative AI to create a Z-matrix for your molecule. The outcomes are not pretty!

Take a look. The perspective includes examples of how MD simulations and the SILCS technology can be used to facilitate antibody-drug conjugate (ADC) development including regions of the mAb that have potential interactions with the drug warhead.

Väldigt bra! I hope all is well!

Representative images on a journal cover of the different types of molecular movement pathways.

Nice to get a JCIM cover! Check out the SILCS-based method for dissociation pathway identification, 10.1021/acs.jcim.4c01814, and the SILCS-Kinetics physics/ML method for rapid estimation (really fast...) of small molecule koff values was just accepted in JCTC.

While I've seen a bad FF or two, the system volume could be so far off that the water can't condense properly.

I have heard from a reliable source that the NIGMS council is rescheduled for sometime In April even though it isn’t posted yet. Not sure about other councils

We are excited to have @alexmackerell.bsky.social this month for our Integrative Modeling in Biophysics e-series!! It’s all about polarizable force field next week. #drude

Increasing the Accuracy and Robustness of the CHARMM General Force Field with an Expanded Training Set Small molecule empirical force fields (FFs), including the CHARMM General Force Field (CGenFF), are designed to have wide coverage of organic molecules and to rapidly assign parameters to molecules no...

For all the CGenFF fans out there, we've undertaken a significant expansion of the training set and extended the coverage to 4-membered rings.

What they are doing is known to the art. Though the method may be more successful than previous attempts, people have been trying this for a long time with and range of methods and varying levels of success. Harold Scheraga would tell you all about it if he was still around!

Get to a physical therapist. I've had good outcomes and I continue to do regular exercises focused on my many issues. Getting old....

Postdoc position in computational structural biology Join our team and contribute to the development of HADDOCK, our integrative modelling software, as part of an exciting EU-India research collaboration.

I have two open postdoctoral researcher positions in my group. I am looking for applicants with interest and expertise in computational structural biology and research software development. These positions are part of GANANA, a collaborative European/Indian project Check www.uu.nl/en/organisat...

🤓Our new article investigates how refined parameters for the Drude polarizable force field perform in capturing complex biomolecular interactions with ions. Congratulations to the team! 👏 #iamcals #hokies #utprosim #virginiatech #whyvt pubs.acs.org/doi/full/10....
