We have a 5am start today as we have both our 96-trap grids open and it is going to be a long day @lydiabeckeriii.bsky.social @bethsallis.bsky.social @profjudiallen.bsky.social @amypedersen.bsky.social

Today two of our team left the island for a short break and Indra, Shaun and Tom arrived. We also celebrated Beth and Indra’s successful first year PhD vivas! @amypedersen.bsky.social @profjudiallen.bsky.social @lydiabeckeriii.bsky.social

An amazing Week 1 on the Isle of May — busy days, lots of mice, and much more to come!

@amypedersen.bsky.social

The “squeak-stake” is a bit of fun we have on the island - aim is to guess the number of mice we trap each day. We have 3 Manchester UG with us this season and Rachel who has never been here before guessed EXACTLY the right number on day 1 @amypedersen.bsky.social @lydiabeckeriii.bsky.social

First trapping day of the summer season 2025 has gone very well. Loggers are out too now so we can monitor how our mice are moving round the grid @amypedersen.bsky.social @grahammunology.bsky.social @lydiabeckeriii.bsky.social @macaulayturner.bsky.social

Lab is set up, food is stashed and first traps are out. @amypedersen.bsky.social @lydiabeckeriii.bsky.social @profjudiallen.bsky.social

We have headed out today for our 4th field season on the Isle of May - good to be back and looking forward to what the next 6 weeks brings @amypedersen.bsky.social @lydiabeckeriii.bsky.social @profjudiallen.bsky.social @sheencr.bsky.social

Day one has involved setting up the lab and re establishing our grids which have lain unused since December 2024 @lydiabeckeriii.bsky.social @profjudiallen.bsky.social @amypedersen.bsky.social

Wild house mice have a more dynamic and aerotolerant gut microbiota than laboratory mice - BMC Microbiology The mammalian gut microbiota is a complex microbial community with diverse impacts on host biology. House mice (Mus musculus) are the major model organism for research on mammals, but laboratory domes...

We compared gut microbiota across >800 lab and wild house mice. Wild mice have more diverse, aerotolerant, and dynamic microbiotas than their lab counterparts. See our latest paper here: bmcmicrobiol.biomedcentral.com/articles/10.... #gutmicrobiome #musmusculus #wildmice

RCN formally responds to Cardiff University’s proposed closure of its School of Nursing | Royal College of Nursing The College is very disappointed and strongly opposes the proposals, which were announced without prior consultation, warning that it poses serious risks to nurse academics, student members, patients,...

Just a reminder that Cardiff University is proposing to cut 400 academic staff and drop nursing, ancient history, modern languages, music and religion altogether - all this while opening a new campus in Kazakhstan at the same time.

Yep. Me neither. 🤯

We're based in the Ashworth Laboratories, King's Buildings, University of Edinburgh. Photo shows the main staircase in the entrance to the Ashworth, stone steps from the 1920s, decorated with a series of bright, colurful banners depicting the science that's tackled in the building.

I'm very pleased to have two lab positions open this week, to join our team looking at immune regulation in infection and co-infection. We're especially interested in tissue-based immunity, cytokine regulation and immune metabolism. Join us! Postdoc (3y) and research technician (12mo) posts open.

A high-lipid diet leads to greater pathology and lower tolerance during infection Summary: Canaries fed a diet high in lipids show more severe disease outcomes than those fed a high-protein diet, with important implications for human and wildlife disease transmission.

A high lipid diet leads to worse infectious disease outcomes. Interesting implications for wildlife food supplementation. Always exciting to have a new manuscript out! Congrats @ashley-love.bsky.social @sauerscientist.bsky.social

Exciting to see this monarch butterfly on the cover of @cp-trendsecolevo.bsky.social this month. In this issue, Astrid Groot and I suggest that parasitism may contribute to the evolution of warning coloration by selecting for anti-parasitic toxins and pigments. Picture taken in St Marks Florida.🧪

As the Texas outbreak grows, how contagious is measles, really? Vaccination eliminated measles from the U.S. 25 years ago. But it can still spread in pockets where vaccination rates are low, like the west Texas county with a current outbreak. Here's how fast.

NPR did a thing. I helped out.

In September in Geneva we applauded a major milestone in the effort to eradicate measles and rubella viruses from the face of the earth.

Today an unvaccinated child has died of measles in the country where the vaccine was developed.

This is not greatness.
