It is with great sadness that the University shares the news of the death of Professor Sir John Gurdon, founder of the @gurdoninstitute.bsky.social Read our tribute to the visionary Nobel Laureate and watch an interview from 2012, just after he won: https://bit.ly/4mM8o3r

Super happy to see also this story out! 👇 7 years of amazing perseverance from @gaowen.bsky.social, who not only performed experimental evolution showing tradeoff between sexual and asexual reproduction, but also identified all key transcription and genome changes. www.biorxiv.org/content/10.1...

Super excited that this story by @borissieber.bsky.social is now on BioRxiv! For decades, we thought there was no MAPK scaffold for the ERK-like cascade that promotes sexual reproduction in fission yeast ... until Boris found it ! See the thread 👇 and enjoy the paper! doi.org/10.1101/2025...
