Fragile Nucleosome
Fragile Nucleosome is an international community of scientists interested in chromatin and gene regulation. Fragile Nucleosome is active in several spaces: one is the Discord server where several hundred scientists chat informally on scientific matters. You can join the Fragile Nucleosome Discord server. Another activity of the group is the organisation of weekly virtual seminars on Zoom. Our webinars are usually conducted on Wednesdays 9am Pacific time (5pm UK, 6pm Central Europe). Most previous seminars have been recorded and can be viewed at our YouTube channel. The schedule of upcoming webinars is shown below. Our third activity is the organisation of the Fragile Nucleosome Journal Club (currently on hold). Our fourth activity is the mentorship program for which you can sign up at the Discord server. If you want to be reminded about upcoming events (listed below) please subscribe to the mailing list here.
