Posted by the Node, on 19 August 2025
We are delighted to bring you the return of our image competition in collaboration with the MBL Embryology course at Woods Hole. We’d like you to vote for your favourite image from the stunning submissions from the students that attended the 2025 course. The winning image will be published on the front cover of Development later this year.
Please vote for your favourite image using the poll at the bottom of the page. The voting will close on Wednesday 3 September.
Thank you and good luck to the following researchers for their contributions:

Marie Lebel, Shivangi Pandey
Regenerating posterior end of a Capitella teleta juvenile seen from the ventral side, 3 days post amputation imaged with a scanning confocal microscope (Nikon AXR NSPARC; 20x, NA 0.8 objective). Nuclei are in blue, neurons in yellow, and serotonergic neurons in red.
Marie Lebel, Shivangi Pandey
Late squid embryo, with a tentacle amputated 3 days prior, imaged with a spinning disk confocal microscope ( Andor BC43; 10x, NA 0.45 objective) . TRITC (yellow) and CFSE (magenta) were injected in the vasculature a day before amputation. The cyan signal corresponds to the inverted brightfield, highlighting the eyes and chromatophores.

Curled up, pondering on existence
An excellent work with beautiful and clear light effects, reflecting the Artist’s in-depth vision and clarity of thought.
Spiral of birth !
They are all beautiful–hard to pick a favorite.
Love the intricacies of the neural network!
Such beautiful definition and shape!
The images are awesome 👍🏻
I wish we could choose more than one. Maybe rank voting? There are so many stunning images.
Sick pic
That’s an amazing image!
This is amazing!
What a amazing image love to see how you created that
Wish more could be selected
They are eall so beautifull
Nature never ceases to amaze
Amazing photos! Shows the divine hand of nature!
Every entry is stunning.. best wishes for the brilliant young scientists!!
These are amazing . Vegetable Creator has made all things beautiful.
Love the details and colors
Good job guys
Goes to enforce the thought that ‘all’ life has fascinating form , often our focus being on the human kind ….
Wow! I am so impressed!
Wow! This is amazing!
I am astonished at the beauty of these images. I am not a scientist so have never seen such embryos like this. It was so hard to pick, all stunning. Rather mind altering.
Fascinating to see these images in their embryonic state.
Beautiful images! Hard to pick a winner . Congrats to all!
