Our cells are experts at navigating inherently noisy and complicated environments.

EMBL researchers are using theoretical physics approaches to uncover fundamental principles behind how cells use complex information to self-organise.

Flyer with announcement of the FEBS advanced course in Amsterdam

Join us in Amsterdam for a FEBS advanced course on "Functional Imaging of cellular dynamics" from 31st of May - 6th of June 2026

Latest work from the lab by Aude Nommick et al., in which we propose a "size-scaling" model for microtubule force exertion that regulates centrosome centration vs decentration during embryo development!

Rare microbial relict sheds light on an ancient eukaryotic supergroup - Nature The discovery of an unusual protist named Solarion arienae, which has a mitochondrial genome with some intriguing features, provides insight into the early radiation of eukaryotic groups.

Each such discovery is a game changer for our understanding of eukaryote evolution, and this paper is no exception. Meet Solarion, which displays yet again novel types of subcellular structures. Congrats to all authors on a fascinating story. #protistsonsky

Three years later, has the $800M edX deal lost its luster? 2U’s acquisition of online course provider edX was once seen as a major win—and potentially even larger disrupter—in the OPM industry. Things didn’t go as planned.

4 years later the new owners are in deep debt anyway: www.insidehighered.com/news/tech-in...

How genetically encoded sensors have lit up neuroscience Tools that track specific molecules in neurons have enabled researchers to probe previously unexplored aspects of neurobiology — although important caveats remain.

7 basic science discoveries that changed the world Ozempic, MRI machines and flat screen televisions all emerged out of fundamental research decades earlier — the very types of study being slashed by the US government.

🧠🌟🐭 Excited to share some of my postdoc work on the evolution of dexterity!

We compared deer mice evolved in forest vs prairie habitats. We found that forest mice have:
(1) more corticospinal neurons (CSNs)
(2) better hand dexterity
(3) more dexterous climbing, which is linked to CSN number🧵

A study that monitored the expression and function of designer receptors called DREADDs in macaque monkeys for a period of three years demonstrates that they are effective in long-term studies of nonhuman primates.

These ancient bumblebees were found with their pollen source Insects have long pollinated plants, but evidence of ancient pairing is rare. Fossils now show bees and linden trees goes back 24 million years.

Scientists just found several fossil bumblebees covered in pollen that directly matches fossil flowers nearby.

The 24-million-year-old discovery reveals the oldest known evidence connecting pollinators to the pollinated.

Can't wait to try this out!

I’m happy to share some plugins I’ve been developping this summer: "Channels and Contrast" and LUTs Manager!
I can’t find new bugs and ideas by now so I need your help to please test them in your machines and report bugs, feedbacks and ideas! forum.image.sc/t/looking-fo...

Jane Goodall’s legacy: three ways she changed science The primatologist challenged what it meant to be a scientist.

I find that so many biologists are also talented artists.

@hsuanpai.bsky.social is a skilled technician and apparently good at any artistic media she touches.. even LB.

My initial assessment of this paper ⬇️ was brief, so let’s have a better look at it:

One protein, two opposing roles: This ‘compelling’ study shows how the same signalling molecule can drive either protrusion or retraction in migrating cells depending on its concentration and activation dynamics.

A very late #FluorescenceFriday.

Reposting one of my favorite timelapses from the past year: EB3-mScarlet3 in a HeLa cell, look at those microtubules grow!

Phage therapy: I found a bacteria-eating virus in my loo It's hoped phages could give us new ways of treating infections which are immune to antibiotics.
