📣 New preprint alert! Co-authored by @spalaciosm.bsky.social and @andreacaldarola.bsky.social :
Quantitative imaging of calcium dynamics with a green fluorescent biosensor and fluorescence lifetime imaging

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.

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!

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

Intestinal villus cells extrude living, following a calcium pulse. Unlike from extruding apoptotic cells, Ca2+ messaging stops at the first neighbors! #FluorescenceFriday

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.

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, known for her pioneering work with chimpanzees, has passed away aged 91

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:

Another #FluorescenceFriday, another movie of the cytoskeleton.
This time around EB3-mScarlet3 and LifeAct-mStayGold co-expressed in U2Os cells!

Today is National Lighthouse Day honoring the historical and cultural significance of lighthouses. I've posted this image before but have reprocessed it. It is the lighthouse at St. Marks Florida. #photography #landscape #EastCoastKin #bnw #blackandwhitephotography #infrared #fullspectrum #clouds

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!
