3. Our new study further complicates this narrative, showing that in this and many systems, records of outbreak geography primarily tell us where we have surveillance infrastructure - and, when you take those signals out, the land use *change* story often drops out. bsky.app/profile/coli...

If you’re a scientist then you *must* watch The Love Hypothesis on Amazon Prime: a fascinating documentary about what *really* goes on in our labs. This educational clip is likely to feature in stats lectures for years to come. 🧪

I'm coming to the end of my maternity leave (jumping into the deep end at the start of term) Was a difficult start - undiagnosed CMPA impacted my baby's health, and my mum passed away just after her birth Despite that, it's been more magical than I ever expected. I'll miss it.

Do you love animal behavior & want to share that joy with younger folks? Write a short article on animal behavior for Frontiers for Young Minds (ages 8–15), co-authored with an undergrad! Part of an international ABS collection. Expression of interest due April 30. docs.google.com/forms/d/e/1F...
Flyer advertising special collection of stories for Frontiers for Young Minds. We invite expressions of interest for a curated collection of short articles on animal behavior to be published in Frontiers for Young Minds, an open-access journal for readers ages 8–15.
This international collection, developed in collaboration with the Animal Behavior Society, will introduce young readers to how scientists explain behavior using Tinbergen’s four questions. Each article will be co-authored by a researcher and an undergraduate, with an emphasis on clear, engaging communication.
Articles will be ~1,500 words and designed for a broad student and classroom audience. Contributors will work with an undergraduate co-author and participate in iterative editorial development prior to submission.
We anticipate selecting approximately 10–12 articles, depending on the strength and diversity of submissions.

There are concerns that Bluesky's impact has faded since the initial hype. This is false. That impression results from reading headlines about social media instead of the hard data. The five HIGHEST points of Bluesky posts mentioning research all occur in the last 2 weeks.

I’m very struck by the fact that kids who grow up in the TFL zone have basically free and highly efficient transport over a huge area whereas in other parts of the country our kids have to pay a lot of money for infrequent and unreliable transport. The impact that has on your horizons must be huge.

Well the award for most cowardly, boot-lickingest academic society has squarely gone to the American Society of Microbiology, who has taken down features of various non-white scientists. Absolutely pathetic behavior. Those articles are now coming up as “under review”. Truly sickening cowardice here.
