Echinoderms already undergo large-scale metamorphosis during larval development, so there are lots of gene 'switches' that produce different patterning.
The loss of a few of these (say, for "trunk") creates an animal that is a sort of "Oops, All-Arms!" body plan.

A radical evolutionary makeover gave echinoderms their unusual body plan

I hope this year will come with new colaborations and the first publication from my current postdoc work... And I hope all my friends have so much success

Migration is widespread in animals, but little is known about its genetic regulation. Peralta et al. compared genomes of lesser long-nosed bats, identifying 10 genomic regions with signatures of selection linked to migration.

It's funny how many gyms I knew this year and as a result of my academic year. And every person, weights and places really moved me even when I'm quite a shy person.

Awesome experience
The SMBE Satellite Meeting in Puerto Varas, Chile, was a resounding success!
The meeting brought together >70 researchers from different continents for 3 days of inspiring science, vibrant discussion, and genuine community building.
Congratulations to the organization!

This endless hunger for publish or perish is just killing My love for science, today i just wanna enjoy My postdoc and do cool research with my límited skills but with curiosity and kindnes.

Sometimes I need to remember that life Is not a race even science is just about do what you really love and learn a lot
