Predator amoeba🦠 C.owczarzaki is both chemotactic and chemokinetic. Our simulations indicate that even just the latter is beneficial to predation. Great work by Sonyia Quick @jasonbains.bsky.social (his second paper!) et al. A serendipitous collaboration with the Gerdt lab. doi.org/10.5967/sh2f...

In yet more devastating news, the VC has confirmed her plans to cut 80% of academic staff from Essex Pathways, our foundation year department. This would effectively close down all our existing foundation year programmes through the back door.
But it's not a done deal yet. Please share urgently.
