Calling all aspiring centromere biologists! Rae Brown (Straight Lab) and I will co-chair the GRS for Centromere Biology, preceding the main GRC on 27th-28th July 2024. Please retweet and register before April 21st to be considered for a talk! https://t.co/eLVNOsGWPW
Warm welcome to our new Principal Investigator Dr Nezha Benabdallah @NsBenab👍! Nezha leads the Chromatin Regulators in Cancer research group. Her scientific interests focus on sarcoma research and chromatin biology. Read more on our website:

Several roadblocks must be overcome to make molecular biology more sustainable, but @GreenLabGuy@ucl argues that we must treat sustainability like we do health and safety in the lab—as a necessity.

This study is amazing! I always wondered if the role of nucleosomes was more about DNA supercoils than 'packaging', these different topologies are a nice hint in that direction. https://t.co/d2ixopyK3l
Did you know JQ1 directly targets BRD4 at centromeres? #Epigenetics is more than gene regulation! To find out more read our updated BioRxiv https://t.co/p12HpSL0SV
Thanks chromatin community! We’ve been digging around in your repetitive DNA (>40,000 ChIP-seq samples) and have discovered a totally unexpected role for BRD4 and JQ1 at centromeres. Very happy to share our preprint. https://t.co/9P1NVWObqt
New research in Science presents a synapse-by-synapse map of an insect’s brain, representing a valuable resource for future experimental and theoretical studies of neural circuits and brain function. https://t.co/VFjsY2f9aU
Biophysics question:
In transcription, RNApol generates positive supercoils ahead of it and negative ones behind it
WHY?
Why doesn’t RNApol instead simply track 1 strand of the duplex, follow its helical twist along the duplex, and thus rotate without any supercoil generation?
@cees_dekker could this instead be an evolutionary question? If RNA polymerase originally evolved to replicate RNA, perhaps the supercoil problem resulting from dsDNA was solved by evolving mechanisms to cope with (and then exploit) this phenomenon? https://t.co/xcadeyjTbS
