Hey! Im a researcher of host-microbe interactions with a focus on bees! My research group is based at the Silwood Park campus of Imperial College London. We're particularly interested in exploring how microbes transmit & what their impact is on pollinator systems. Where possible we try to employ new techniques or combine multiple cutting-edge processes at once.

New visualization on my #climatechange indicators page - https://zacklabe.com/climate-change-indicators/ 📈

Now I am showing global temperatures compared to only over land or only over ocean areas. This is all relative to the 1850-1900 pre-industrial baseline. The graphic will be updated monthly now.

So.... the ongoing move of #neuroscience from twitter to mastodon has left me feeling like I am switching apartments. The old one is disheveled and empty and the feed is full of junk, and the new one is unfurnished, a bit cold and the fridge is still empty. And my friends are not stopping by a whole lot to say hello (not that I am home all that much yet). It will be FINE. I'll start resuming tweeprints soonish.

The Canine Brains Project has finally joined Mastodon! Here's our #introduction! 🐶 🧠 🎓

We are scientists from Harvard's Hecht Lab who are studying dog #neuroscience and #behavior. We are interested in how #genes, #neuroanatomy, #dogtraining, and lifetime experiences shape dogs' minds. We also study how dog brains and behaviors #evolve.

I just taught my "problems in taxonomy" lecture. I always give this fantastic website as home reading. Someday I will find out who created it - a marvelous collection of puns, insults and wordplay in biological nomenclature. If you know who made it... tell them to contact me #evolution https://www.curioustaxonomy.net/puns/puns.html

3,013 neurons, half a million synapses: the complete #connectome of the whole #Drosophila larval brain!

Winding, Pedigo et al. 2022. "The connectome of an insect brain" https://www.biorxiv.org/content/10.1101/2022.11.28.516756v1

We’ve mapped and analysed its circuit architecture, from sensory neurons to brain output neurons, as reconstructed from volume electron microscopy, and here is what we found. 1/

Then we studied recurrent circuits in the #Drosophila larval brain.

By starting bi-directional multi-hop signal cascades at any one cluster, we found that the cluster containing the dopaminergic neurons (DANs) of the centre for associative learning and memory, the insect mushroom body (MB), present the most cascades where the beginning and the end of the cascade is itself!

In other words DANs, which mediate learning, are the most recurrent neurons in the brain.

Remember friends, a dinosaur isn't just for Christmas. You should probably stop to think whether you should, even if you could.

But *if* you could, I've made this handy guide.

Credit where credit's due.

@arc_gov_au@twitter.com got #DiscoveryProjects #DP23 done in just over 6 months.

Thanks to ARC staff for this. It matters! The earlier these are announced, the better for Australian research & researchers.

Hopefully this is sustainable for ARC staff & processes.

Chemist Rachel Fuller Brown was born #OTD in 1898. She discovered the antifungal antibiotic nystatin while doing research for the NY State Department of Health, hence the name.

Rather than keep the profits from the drug, Brown (standing in the photo) and co-discoverer Elizabeth Hazen assigned nystatin’s patent royalties to the nonprofit Research Corporation of New York, to help support other researchers.
