Hi #devbio #devbiol Mastodon,

If you like sharing and discussing #preprints, you might like to know that Development publishes 'In preprints' articles.

Please do feel welcome to get in touch if you would be interested in writing an article on a preprint - or preprints - that interest you.

Learn more about this article type here: doi.org/10.1242/dev.200711

📢 Please RT
Join our #fly neuroscience lab.

4 year fully funded #phD fellowship to study how animals make decisions during conflicting situations. #neuroscience #drosophila

Deadline 20th Jan
Get in touch with questions.

Excited to come across the beta of a version of Internet Archive focused on academic journal articles. The version for books is fantastic, so am hopeful about this:

scholar.archive.org/

(but surprised that it apparently starts with 'eighteenth-century journals', rather than 17thC journals... #JournalDesScavans is available on #Gallica; #PhilosophicalTransactions is available from #RoyalSociety)

Galactica sounds like a powerful tool! —“Can summarize academic literature, solve math problems, generate Wiki articles, write scientific code, annotate molecules and proteins, and more.”

galactica.org

Covers everything from mashing bananas, cooking pasta, films on black tea to rheology of Oreos 🍌 😋😊 All you wanted to know about physics of fluids, food, science and education!

EMBO/#EMBO Press has two scientific editor positions open, one for The EMBO Journal and the other at Molecular Systems Biology/EMBO Molecular Medicine.
Both jobs are in Heidelberg.

And we have over 1600 scientists who registered at @beatty 's opencheck.is/scitwitter to preserve the Twitter Science Graph!

New graphic at leonlotter.de/twittergraph/

I updated the code, new layout, no live physics simulation anymore due to performance issues (sorry about that 😬).
In time, I might put together a self-updating online app 🤓.

Sarcomeres assembling in an immature heart muscle cell videoed through a microscope. A protein that localizes to “Z lines” and their precursors “Z bodies” is shown. If you look carefully you can see the Z bodies concatenating into Z lines. Unless this GiF does not upload. In that case you will just see Z bodies sitting there and I will continue to work on posting here. #cellbiology

Hello there! #introduction

I am a postdoc at Université Laval in Québec working in collaboration with Michelin. My current work is about #ErrorEstimation for #FiniteElements methods. More precisely, I am working on gradient reconstruction for multimaterial problems.

I am also a #fenics user and I am interested in #NonLocalModels and more precisely in the error estimation in the finite element discretization of fractional partial differential equations.

We’re looking for in vivo rodent electrophysiologists interested in complex behaviour to come and work in beautiful Glasgow. Advert to appear shortly, but meanwhile, if you’re interested and will be at at #sfn2022, come and find me! (Both postdoc and tenured positions available)a

I wanted to advertise a postdoc position in beautiful Norwich, that is for 3+2 years.
We are looking for a bioinformatician, or someone who wants to become one. In the post we will investigate gut metagenomes using 3rd gen sequencing, deep learning, to investigate pan genomes and microbial adaptation, mostly using human gut time series of various host ailments.

Please retoot or send to interested parties, thanks!

Hi #MassSpec #TeamMassSpec, #massspectrometry, quick tips...

➡️ Try posting with hashtags like #massspec AND (this is new ❗ ) ALSO @massspec (our group)

➡️ Search for, then follow, the @massspec group to get related stuff without having to click on hashtags like #massspec. You're effectively subscribed to any posts that mention @massspec then.

➡️ Browse other groups on a.gup.pe/ like @phdlife, @classicalmusic etc or make your own, like @massbank_consortium created by @toschber

SARS-CoV-2 origins 

A strong opinion piece arguing against a lab origin for the -CoV-2 .
The authors provide quite an extensive review of the arguments in the discussion.
I agree that we should focus efforts on studying if we want to prevent further pandemics.

So cool. Look at those ridges

Nuclear tension controls mitotic entry by regulating cyclin B1 nuclear translocation 

"[...] a tension-dependent signal on the that sets the time for nuclear envelope permeabilization (NEP) and mitotic entry. This signal relies on , which unfolds the nucleus during the G2-M transition, activating the stretch-sensitive on the nuclear envelope and regulating the nuclear translocation of B1.[...]"

Ever wonder how flowers get their colors?

Anthocyanin pigments, stored in vacuoles of petal cells change color with pH (acidity). The Japanese Morning Glory Ipomoea tricolor var. Heavenly Blue, changes from purple-red to blue in the early hours of the morning. The pH change is caused by NHX1, a transport protein that replaces protons with sodium or potassium ions. Similar genes in humans are critical for function of neurons and other cells.

A few years ago I made this flow chart of which Mastodon posts end up in which timelines!

So, you can see how each instance will have a different local timeline, and even a slightly different federated timeline - and you can see why the federated timeline moves so much faster than the local one, too.

This is why it's important to boost good posts and use hashtags - the fediverse is fragmented and harder to search by nature.

Hello, #Mastodon! Greetings from my hospital bed.

This image depicts blood vessels in a pigeon’s head. It was captured by the veterinarian Scott Echols as part of an ongoing endeavour known as the Grey Parrot Anatomy Project, which aims to develop ways to aid diagnosis and treatment for a host of animals, from birds to humans. By understanding what is normal, doctors and scientists are better positioned to identify and ultimately treat the abnormal. #sciart #ScienceMastodon #medicalhistory

Combinatorial interpretation of BMP and WNT allows BMP to act as a morphogen in time but not in concentration. 

"[...] varying the duration of leads to either pluripotent, mesodermal, and extraembryonic states, while varying the concentration does not cause efficient mesodermal differentiation at any dose [...] appropriately timed pulse of BMP induces to a mesodermal fate more efficiently that sustained signaling at any concentration. [...] this effect is due to a combinatorial interpretation of the applied BMP signal and induced endogenous signaling."
