New paper from Ikeda et al. on the biogenesis of chitin bristles in the annelid with nice reconstructions and a chitin synthase knockout.
Bristles are formed in a process of biological 3D printing. @biology

Beautiful new study by Michael Bok, Macali & Garm on the high-resolution eyes of the enigmatic alciopid annelids, from Ponza island.
"Our results show that the eyes of alciopids possess the anatomical, morphological, and physiological properties requisite for high resolution tasks and object vision"

@Sal Thank you! Indeed, the opsin is not the sensor, but we can use a mutation in the opsin gene to disrupt the ciliary superstructure and then we see a phenotype in pressure sensing, and also in UV light sensing, as we previously described: https://elifesciences.org/articles/36440

Our SEM finally made it across the Channel from Exeter to .

It took us several months of bureaucracy, including over 200 emails to sort out the paperwork.

Nobody involved had a clue about the customs documents.The UK and EU branches of the microscope company, the two universities, the shipping company...
If you scale this up to the entire UK economy, it is easy to see how massively damaging must have been.

Our new EU PhD Network is hiring! We have 12 PhD positions in Germany, France, UK, Italy and Sweden.

The broad topic is evolution of sensory cell types in animal diversity: multidisciplinary training in 3D cellular reconstruction (volume EM), multimodal data analysis and science outreach.

People who write : do you write about

  1. projects that you’ve already almost completed (hiding the fact that they’re almost completed, so that you can use the funding for completely new projects), or
  2. new projects that you haven’t really started yet (for which you might just have some preliminary data)?

Do you think 1) is unethical? Do you think 1) is necessary? Do you think 1) has the highest chances of funding? Please comment :)

@cowboycatranch @albertcardona @elduvelle @janbogar @RichardShaw @maartjeoostdijk We also published the lab's publishing policy and new lab members have to agree. We have been publishing in non-corporate venues for many years now and I don't think that the career of people in the lab or my career suffered from this. Integrity, openness and the quality of our science is all that matter to us, not titles or magic tokens https://www.cos.uni-heidelberg.de/en/research-groups/gaspar-jekely/our-approach-to-publication

But, please, please stop spreading this urban legend that adult sea squirts do not have behaviour and a nervous system. They do, furthermore: "most parts of the ascidian larval CNS, except for the tail nerve cord, are maintained during metamorphosis and recruited to form the adult CNS"

Anyone knows of a app that allows you to do drafts one or more ? (Not facebook - actual threads)
@feditips ? 🙏

Edit: to be more specific: I’d like to be able to create a thread in the app, so a sequence of posts (not just 1 post) that can each have text, images etc. and are in a specific order, and if need be save it and come back to update it later, and eventually post it.
Also, I am using iOS and desktop (Windows). If you check the comments you’ll see that Fedilab seems to allow this but for Android.

Thanks for all the input so far!

You can do this with the toot tool:
https://toot.bezdomni.net/introduction.html

Author your complete thread in one .sh file and post it with all media etc. You can reply as many times as you want.

#!/bin/bash

toot post "toot 1" > toot_id.txt -m path/to/image.png -d "My image"

id=$(grep -oE '[0-9]+$' toot_id.txt) && echo $id

toot post --reply-to $id "reply to toot 1" -v 'unlisted' -m path/to/image2.png -d "My 2nd image"

toot post --reply-to $id "second reply to toot 1" -v 'unlisted'

people! How do you decide which journals to submit to? What factors to you consider? Excluding glam mags like Nature, Science, etc. What is your favourite journal? I always found J Neurosci reviews a bit savage so reluctant to go there. Other options?
