The blastopore of bryozoan embryos

This is a bryozoan embryo exhibiting its blastopore. These animals are discreet but ubiquitous in oceans and lakes all over the world.

What we see is the DNA inside the nucleus of the cells of the embryo. The color gradient indicates if the nuclei are closer (yellow) or further away (purple) from the microscope camera.

The embryonic cells are arranged in a circle and form a central opening that we call the blastopore. This opening, in bryozoans, will become the mouth of the animal after the embryo develops.

You can follow the process on video or learn more details in the paper.

What about our mouth, where does it come from?

The PostdocNet logo

The PostdocNet is an organization that represents the collective of postdoctoral researchers working in the Max Planck institutes spread throughout Germany.

The network is relatively recent, only founded in 2019, but has already put forward important proposals to improve the working conditions and career development of postdocs.

A few months ago they contacted me to help re-design their logo and website to better represent the identity of the organization. Since I enjoy creating websites and I’m sympathetic to the mission (disclaimer: I’m a postdoc) – I accepted the challenge :)

After some rounds of feedback from the PostdocNet working groups, the final version of the logo is finally here:

The new PostdocNet logo.

You can read more about the story behind it here.

Now the website is next…

Fruit fly embryo under lightsheet microscopy

A short video that I made about the embryonic development of the likeable Drosophila, also known as fruit fly or vinegar fly, won an honorable mention in the Small World in Motion.

A single embryo imaged from four different angles.

The details on the techniques I used and the video on its full resolution are available for download and re-use on the Wikimedia Commons.

A typical lightsheet microscopy session

Here is how a typical session of imaging embryos under Lightsheet Microscopy goes. A glimpse into my day-to-day work :)

Assemble the incubation chamber:

Collect and mount the embryos:
