Great to see copepods & krill headlining in the news

Today I had a productive day because I managed to trim my metabarcoding sequences and solved a problem I was stuck on. I know it’s kind of an easy part and maybe funny to you, but I’m really proud of myself! 😆😆😆

The only joy I have these days is walking this lizard through the pages of a book. For hours, the lizard and I walk and walk until we lose ourselves in the crowd of pages.

First time working with metabarcoding—curious, confused, and stressed about doing it right.
But in the end, I find eDNA and metabarcoding to be truly fascinating worlds—ones you can just keep swimming in.

Charles Darwin is best known for his work on evolution.

But he was a prolific scientist who studied much more. Now, over 20,000 of Darwin's letters, books and publications have been recognised as a UNESCO heritage.

The documents will join other important archives such as the illuminated manuscripts of Charlemagne’s court.

We like to be out in nature so much because it has no opinion about us.

Can you feel the freedom of spring?
The wind gently passing through your hair,
The first blossom unfurling in the light—
A moment of release, yet born of pain.

I'm working on the functional diversity of zooplankton. I feel it's not accurate because results depend on the traits we choose,which can be subjective. I wonder if there’s an issue with functional diversity, or am I just at the beginning and haven’t grasped it yet? #Zooplankton #FunctionalDiversity

[New Paper] is on the COVER of @science.org !!
FIRST genome-phylogeny of MOLLUSCS (snails, clams, octopus, etc.) complete with ALL classes —incl. the mythical "living fossil" Monoplacophora— reveals how they evolved the most diverse body forms of all animals!

I was thinking about language extinction and its importance. Turns out, just like functional richness in ecology, linguistics has a similar concept. Fascinating!
(In linguistics, FD can describe the range of cognitive, cultural, and communicative functions)

my proposal defense.
I can't deny how excited I am about making a PowerPoint on zooplankton—after all, they're just so beautiful!

Understanding the various indices in functional diversity is a bit tricky, and the more I read, the more confused I get 😄

Many people ask why I don’t abandon my project when funding is not provided along the way, but I feel like my research project is like a child that I need to protect and help grow, even in difficult times.

These tiny copepods have little blue hearts on their backs.
