My first PhD paper is out in Nucleic Acids Research! We describe "Ab-trapping" - an antibody artifact that distorts assays relying on antibody diffusion (microscopy, CUT&Tag, CUT&RUN). The revisions made the story much stronger. Check it out! doi.org/10.1093/nar/...

Antibody-trapping presents a widespread pitfall for microscopy and genomics in the nucleus
Abstract. Chromatin has a complex 3D structure and diverse binding proteins that coordinate the genome’s most essential functions. Many microscopy and geno

With a few days since it's been out @keribackus.bsky.social @oligopain.bsky.social and I wanted to highlight a few of our favorite aspects of POCA for photocatalytic proximity labeling of DNA, RNA or proteins. (1) POCA builds on standard in situ hybridization and immunofluorescence workflows.

Announcing such a major change to NSF GRFP this late in the cycle is incredibly cruel. 2nd yr students (mine included) have been working so hard on their proposals despite ongoing uncertainty. They are driven and passionate about being outstanding scientists and helping those coming up behind them.
This means individuals in the following statuses at the time of application are eligible:

    Undergraduate in the final (senior) year of a bachelor’s degree program
    Bachelor’s degree-holder with NO enrollment in a graduate degree program (non-degree graduate coursework allowed)
    Individual enrolled in a joint bachelor’s-master’s degree program with at least three undergraduate years completed  
    First-year graduate student in their first graduate degree program with less than one academic year completed in the degree program (according to institution’s academic calendar)
        Individuals enrolled in joint bachelor’s-master’s degree programs are considered graduate students. For GRFP, joint bachelor’s-master’s degrees are defined as degrees concurrently pursued and awarded.
        Not be a current NSF employee.

Applications that do not meet eligibility requirements will be returned without review as being ineligible for a fellowship.

Transcription processes compete with loop extrusion to homogenize promoter and enhancer dynamics
Gene promoters and enhancers share the same constrained mobilities during transcription, opposing cohesin-mediated loop extrusion.
