ATP synthase activity boosts membrane proton acceptance and lateral diffusion | PNAS In most organisms, ATP synthesis is powered by the proton motive force (pmf) and catalyzed by ATP synthase. While the chemiosmotic theory originall...

📣 I was waiting for this paper for a while 🥳
Our new paper in @pnas.org shows that ATP synthase drastically alters membrane properties related to proton diffusion. Funded by @volkswagenstiftung.de

Come join us in a new journey to unravel some of the mysteries of cellular aerobic respiration.
Plus, being close to the Peak District:

🌄 An opportunity to study at the University of the Year for Student Experience in the UK at The University of Sheffield. An additional bonus: being minutes away from the gorgeous Peak District.

Now, it is our time to shine and to use the new tools to reveal some of life's biggest mysteries.
The nature of the PhD studentship is cross-disciplinary, involving biology, chemistry, and ultrafast spectroscopy.

Feel free to contact me for any additional information.

🥳 New review paper! I am pleased to share our new review paper written with my previous post-doc, Srestha Basu.
This review focuses on CPL. But, unlike many reviews on CPL, it highlights the role of high-hierarchical structures in inducing CPL activity.

It all started a couple of years ago in a discussion with Mario Mencia about proton transfer in bacterial membranes vs. archaeal ones. I told him we can give it a go, and we found some interesting, unexpected capability of ether lipids to support proton diffusion.

The role of ester- versus ether-linked phospholipids in the ability of biological membranes to accept protons and support proton diffusion In biology, the distribution of ester-linked versus ether-linked phospholipids is meaningful, such as in the abundance of ether-linked phospholipids i…

With that note, Happy New Year to everyone. May the new year bring winds of good change and peace (or at least quiet) to our world.

I want to thank the Technion in Israel, which will always be my second home and where I have made so many good friends. Making that decision was one of my hardest, and I am sad that the state of my home country has pushed me away from the workplace I love so much. ->

I want to thank the University of Sheffield for believing in my science and offering me a full professor position in Chemistry. I am looking forward to making great science with the great people I have already met there. ->

🧵As the year ends, I wish all my friends and colleagues the best in 2025.
For me, 2024 was quite a ride. While some of you may know, I never wrote anything publicly about it. Earlier this year, my wife and I decided to move out of Israel and start a new adventure. ->

It is one of these black science magic that you don't understand in the beginning how this counter-intuitive thing can work, but suddenly it does. Congrats to Amit and Ziyu for this achievement.
