Happy our review on the lateral plate mesoderm is out @Dev_journal, with @karin_prummel & @Susan81643382 (open access).

Our first attempt at reviewing the fascinating, wacky, complex biology as Development at a Glance with poster!

The LPM forms several central cell fates and organ systems, including the heart, endothelium, blood, limb connective tissue, and much more.

This seemingly weird combo of downstream fates seems unrelated the adult body - but they all share a common LPM origin!
Our review now attempts to summarize how LPM's development (and possible evolution) ties these diverse downstream fates together.

We also discuss that not all "mesoderm" is equal:
the LPM forms as dedicated mesendoderm lineage early on, both in development and evolution.🧬🧬🧬
We further summarize key points of how the LPM's individual downstream fates form - far from complete, hope you find your favorite LPM lineage(s)!

Kudos to @karin_prummel & @Susan81643382 for their detective work... Image
...and apologies for not being able to include ALL THE COOL SCIENCE out there on LPM cell and organ fates & disease modeling!
Speaking of disease:
considering a joint fate origin in the LPM provides a framework to think about several syndromic congenital diseases (definitely helps me!).

Case in point, heart dev & cardiopharyneal field (feat. a correct Ciona heart schematic, thx @lionlchristiaen❤️)! Image
Many thanks to @Dev_journal & @amjeve for this opportunity and the engaging, efficient, and enjoyable editorial process - including three constructive reviewers.

Our lab's first pub with @CUAnschutz affiliation! 🥳🎏
Importantly, @amjeve also coined the color "LPM Green" that we will try to stick to in our lab for consistency :)! Image

Remarks on faculty job searches (as 'tis the season):
Chances are, as a faculty candidate you apply to several job ads.

Dozens. More.

You wait. You hope.

(quick thread)

 #PILife #PDLife #AcademicJobs
Some places will respond with a rejection pretty quickly. Form letter.

Sometimes hilariously addressed to Dear [Applicant Name3].

Are you just a number? At this stage, likely.

Others never get back to you. Or years (!) later.

2/n
This is normal and as in any higher-level job with lots of competition.

The waiting, the rejections, and the no-responses are depressing. Discouraging. At times unhealthy.

"Does nobody care about my ideas? My science? Me?"

As undergrad, I struggled immensely with this: reading and omg understanding papers.

Especially as non-native English speaker.

I did develop a system that helped me back then.

Bear with me it is pretty...mundane. 1/n

#reading #PhDLife #PDlife #undergradlife #papers #science
I printed each paper. And while reading I used a yellow, a green, and a pink highlighter.

When reading, I labeled every first mention of an abbreviation in green.

This helped me to find their meaning quickly again when deep into the text.

2/n
In pink, I labeled key questions and take-home messages.

If done correctly, you can look at pink sentences alone and recap the whole paper.

Peo-rip: first and last sentences of paragraphs often are pink sentences.

Pro-tip 2: write papers that have pink sentences.

This is every molecular biologist's nightmare - vector and PCR product contamination across samples.

We can sequence so deep now that all kinds of details come to light!
I bet lots of us "reproduced" aspects of this in our own labs - i.e. a genotyping you do often starts to show up in every PCR you do, etc.

DNA always finds a way.

#mobio #devbio #benchwork
To add two anecdotes.

A good friend during my PhD did mass spec on Drosophila samples, and couldn't figure out what the predominant recovered peptides were. They overpowered everything else.

Human Keratin.

He made sure to wear gloves after this. 1/2

Honored & grateful to receive the @ZDMSociety award in these trying times.

The award also recognizes our amazing international trainees using #zebrafish #devbio as cardiovascular disease model, first @UZH_en & now @CUAnschutz - and our fantastic collaborators!

Thx all🍾🐟!
Special shout-out to @FelkerAnastasia @karin_prummel @aburger2009, our collaborators @ClaudioCantu81 @d_zimmerli @KevinMMA13 @DanielaPanakova @PanakovaLab @George_Hausmann and all who were part of our BCL9 work cited in the award:

Fun fact:
most PIs themselves never had (or sought) any actual formal training for any of this. Similar for teaching or mentoring.

Frequent attitude:
"winging it" is normal/badge of honor/funny.

Don't want to say it shows. But it totally does.
Few quick additions:

"Budgeting" or lab budgets are often not that complex. Salaries are pre-defined. Reagents over time sum up to an average consumption and can be estimated. And often you get help.

I always dreaded the book keeping but it's useful and gives peace of mind.
"People management" is a deep rabbit hole that many see as "learning by doing". Some is, indeed.

But workplace psychology, supervision, progress tracking et al. is done in industry & military since decades/centuries. This has language and framework. Useful to seek out.

Just co-chaired the first #ZFish20 concurrent session at #TAGC20 @GeneticsGSA.

Short thread after the fact:

1) WE CAN DO THIS!

1/7
2) Great technical support with setting up, etc. from the assigned technicians.

No need to sweat, and it was great to see enthusiastic smiles and humor in the 10min before the session start!

2/7
3) Session chairs:
use a timer app and also coordinate through the panelist chat with your co-chairs and speakers.

It *MIGHT* happen that you forget to set your timer occasionally, so having backup is great!
