I was looking for refences in this paper we wrote, comparing the effects of behavioural differences and social feedback in collective movements, when I realised we added faces to the monkeys! Completely forgot about that 😂 they are only visible if you zoom in the pdf.

Just attended these talks from NatGeo Explorers in Asia, and was amazing! Really wonderful to see the work they are doing, and there was a broad range of topics. From biologging data in penguins to a sociological study in Gaza.

Had the most unprofessional experience ever with a British Eco Soc journal. Long story short:
✅ Handling editor + 3 reviewers love the study. At round 3 of revisions, only minor details, a 4th reviewer claims a bunch of nonsensical flaws.
❌ Editor rejects paper. 9 months wasted.
See 🧵for details.

What a delusional world... At least 26 Palestinians killed in Israeli attack, 15,000 patients risk dying while waiting for Israel to enable evacuation, and the only thing Vance has to say: the 'President's' peace is still holding.. peace for who?

Finally, temperature dropped below 26C yesterday night! I was able to sleep with the window open, no AC 😌
First day, since summer started, that I'm thinking of having lunch out in the garden!

What's the #weather like in #Japan? 3 months of summer (= burning sun, 90% RH, +30C at night), two weeks of nice weather (happening now!) followed by typhoons and a super dry winter. Then, two weeks of nice weather again, before rainy season & back to summer.

Today in a restaurant I asked: 'Can I have this pasta without bacon please?' -'Of course' says the waiter very kindly. Well, pasta came without bacon indeed, but cooker added mini-sausages instead 😅 I appreciate the effort, but the 'bacon' itself was not the issue 😂 I'll be more specific next time..
