Lightnews — Scholar-powered news

This prize celebrates both my past work @msarscentre.bsky.social and my current research at the Institut de Biologie Valrose (iBV).
It’s a huge source of motivation to keep exploring, creating, and hopefully inspiring more young women to follow their own paths in science. 💪🌍

The past few days have been incredible — surrounded by brilliant, passionate women from all fields of science.
So much talent, curiosity, and kindness in one place! It reminded me how powerful it is when we lift each other up and keep pushing boundaries together. ✨

Still can’t quite believe it 💫 I’ve received the L’Oréal-UNESCO For Women in Science “Jeunes Talents” France 2025 award!
I’m so deeply honored — this recognition means so much to me, both as a scientist and as a woman who loves research. 💙🔬 1/3

Rest in peace Jane Goodall, a true giant among scientists. Your breakthroughs into the secret lives of chimpanzees viewed through an anthropomorphic lens – without yet knowing that science had forbidden it – changed science forever, and with it how we see ourselves.

Excited to share our last paper describing how intestinal stem cell migration promotes gut regeneration!
www.nature.com/articles/s41...

Pvf1-Pvr-mediated crosstalk between trachea and gut guides intestinal stem cell migration to promote gut regeneration - Nature Communications

Adult stem cells often reside in specialized niches that they exit upon injury. Here they show that in Drosophila, after damage the gut-associated trachea produces the PDGF-VEGF-related ligand Pvf1, which acts as a guidance cue directing ISC migration toward injury sites.

Harvard Funding Cuts Endanger the Massive Fruit Fly Database That Powers Genetic Research | News | The Harvard Crimson

FlyBase lost a multimillion dollar grant when the Trump administration cut off Harvard’s federal funding in May. Now the repository is laying off staff — and researchers worldwide are worried.

Super excited for our new preprint on the role of tissue mechanics on the neurophysiology and behavior of Ciona. A tour de force by @midlangandreas.bsky.social and other lab members combining tension sensors, calcium imaging, optogenetic tools and of course behavior. More to come soon.

Michael Sars Centre @msarscentre.bsky.social · Apr 22

Congratulations to the Chatzigeorgiou lab @mchatzigeorgiou.bsky.social for a new preprint 🤩👏 @midlangandreas.bsky.social and team studied the mechanical forces at play during #Ciona postembryonic development, and found links to larval chemosensation and settlement behavior 🧪 Read the article ⤵️

Mechanics regulate the postembryonic developmental maturation and function of sensory neurons in a pre-vertebrate chordate

Physical forces are emerging as important contributors to a wide diversity of biological processes across multiple scales and contexts. The development of the nervous system is infuenced by mechanical...
