Hey folks, as news of Watson's demise spreads, please don't set aside his weighty legacy of misogyny and racism. He was truly among the worst of us. www.vox.com/2019/1/15/18...

Thinking only of Rosalind Franklin today, and what was stolen from her (and so many other female scientists alongside her).

Soon available in my group: 1 PhD position to investigate prokaryotic histones. See our recent work that highlights the existence and diversity of prokaryotic histones (e.g. Schwab et al., TIBS, 2025; Schwab et al., Nat Comm, 2024; Hu et al., Nucl Acids Res, 2024). Please DM for informal enquiries.
