If you are @hhu.de and interested in a really cool science outreach project from @daumannl.bsky.social lab members Pia Heinrichs and @sophieguti.bsky.social make sure to stop by the sci comm luncheon ☺️

#chemsky here is our recent preprint on cyclic lanthanide-binding peptides. @sophieguti.bsky.social @hhu.de and our collaborators @hzdr.bsky.social and @kit.edu have put in an immense amount of analytical work to understand binding in these peptides. Check it out! We even snuck some #curium in 🤓🧪

Let’s Get Cyclic – Influence of Head-to-Tail Cyclisation of Lanmodulin-inspired peptides on Lanthanide Affinity and Structure Over the recent years lanthanide-binding proteins such as lanmodulin, a naturally lanthanide-binding EF-hand protein from Methylorubrum extorquens AM1, as well as protein-inspired lanthanide-binding peptides have become of increasing interest for the development of separation and recycling methods for rare earth elements. For the first time, a set of head-to-tail cyclised lanmodulin-inspired peptides and their complexation behaviour towards lanthanides was comprehensively examined in aqueous media using time-resolved laser induced fluorescence spectroscopy (TRLFS), isothermal titration calorimetry (ITC), nuclear magnetic resonance (NMR) and circular dichroism (CD) spectroscopies, complemented by molecular dynamic (MD) simulations and advanced mass spectrometry methods. Results obtained from this multi-method approach evidence that the head-to-tail cyclisation can indeed increase the lanthanide-affinity in natural sequences and positively impact the pre-organisation of the metal-free peptide while limiting the amount of formed complex species in comparison to linear analogues. Furthermore, the impact of minimal sequence alterations by inserting glycine is shown to be useful in NMR experiments for probing alterations in the local environment of neighbouring amino acids potentially involved in coordination. Lastly, KD values for the peptides with the whole Ln series (except Pm) and the actinide curium are presented.

#CASFutureLeaders really is a game changer for your leadership development - would highly recommend every early-career scientist to apply for next year! 🤓

#Wisskon25 - Simone und ich hatten super viel Spaß dabei @munichsoapbox.bsky.social zu vertreten und das Projekt bekannter zu machen😎🥼 Danke @nawik.de für die Möglichkeit! Vielleicht gibt es in ein paar Jahren ja Soapbox Science Events in ganz Deutschland?😍🤔

Soapbox Science. Was passiert, wenn man Kinder bittet, Wissenschaftler:innen zu malen? Anfang der 1980er wurden zu fast 100% Männer gemalt. Es hat sich gebessert zum Glück #wisskon25

WissKon25 - NaWik - Nationales Institut für Wissenschaftskommunikation Die WissKon25 Die WissKon25 – die NaWik-Konferenz für kommunizierende Forschende – findet am 2. Dezember 2025 in Karlsruhe statt. Einen Tag lang tauschen sich Wisskomm-Interessierte zu Themen rund um ...

Successful #türenauf mit der Maus Event 2025 @hhu.de done and dusted! Thanks to all the helpers @sophieguti.bsky.social @joguti.bsky.social Theo, Sarah, Suny, Lukas, Tom, Rachel, JJChemistry, Hannah and to @markussuta.bsky.social for lending some of his group members to give additional lab tours!

Lotti hat früher unsere Kinder gesittet. Vielleicht kennt ihr sie vom @gdch.de Podcast "Alles Chlor!".
Jetzt zieht sie für ihre Doktorarbeit bei @cutsail-lab.bsky.social 🧲 nach #München 🍻 und sucht eine #Wohnung.
Wer was weiss, sagt bescheid, sonst gerne RP ☺️ #chemsky

Super cool!😍 Bei der Maus sein, egal ob vor oder hinter der Kamera einfach immer toll!😎

Hope is not something I feel frequently right now, so yesterday was a very special day.

I had the privilege to spend the day with the #CASFutureLeaders - meeting each of these brilliant scientists who are changing the world through their leadership and outreach was so uplifting and inspiring!

Definition of imposter syndrome: speaking at a workshop right after #ChemSky stars 💫✨ @drdre4000.bsky.social and @jenheemstra.bsky.social 🥰 Such an honour to share the stage with them at the #CASFutureLeaders programme 🎉

Already learned so much at #CASFutureLeaders while having a great time with all the other participants🙌🏻

Kicking off the #CASFutureLeaders 2025 program in Columbus with an awesome welcome gift from CAS curated by @petercarlton.bsky.social and Nicole! So excited to have finally met the incredible cohort and can’t wait for the week ahead starting tomorrow with @storycollider.bsky.social
