As conference season is coming up keep this in mind ☝🏻

Normaler Tag in Potsdam 🤯

Säugetiere in Seenot? Let's go:

The EuroBIC folks did a great job communicating the process of picking oral presentations. Three e-mails announcing the ongoing and upcoming decision. Very transparent. Only for the final announcement to go into spam for everyone, which made another e-mail necessary 😅

While I am excited for their new music I cannot forget being rather unimpressed with BoC's last album, which dropped after a cool promo campaign, too

Iconic shot!

Either I was walking too fast or someone painted the bedroom wall last night 🧐

This composite photograph features a warm, close-up portrait of Margaret Eleanor Atwood (born November 18, 1939), the internationally acclaimed Canadian author, poet, and literary critic widely regarded as one of the most influential writers of the late 20th and 21st centuries. In the main image, the older Atwood gazes directly at the viewer with a gentle, knowing smile, her short curly gray hair softly framing her face. She rests her left hand against her cheek in a relaxed, contemplative pose, wearing a dark top accented by a patterned gray-and-yellow scarf. The solid black background isolates her face and upper torso, creating an intimate and timeless studio portrait. Overlapping in the lower right is the iconic black-and-red cover of her 1985 dystopian masterpiece The Handmaid’s Tale, showing the famous red-robed figure with a white winged bonnet and the bold text “THE #1 WORLDWIDE BESTSELLER” and “MARGARET ATWOOD.”

Margaret Atwood 𝘛𝘩𝘦 𝘏𝘢𝘯𝘥𝘮𝘢𝘪𝘥'𝘴 𝘛𝘢𝘭𝘦 was first published in Canada #OTD in 1985 (US, Feb 1986).

The book has stayed in print for >40 years, been translated into >40 languages & was adapted into a 1990 film, a 2000 opera, a 2017 television series & and other media.

A Zundel ion in the catalytic proton transfer pathway of [FeFe]-hydrogenase [FeFe]-hydrogenases are metalloenzymes that catalyze the interconversion of protons, electrons, and molecular hydrogen (H2). Their active site cofactor consists of a [4Fe-4S] cluster ([4Fe]H) and a di...

Anlässlich des weltweiten Tages der Erde am 22. April beteiligt sich die Universität Potsdam mit ihren Umweltwochen daran, das Bewusstsein für Klimaschutz und Umweltfragen zu stärken. Das Programm und weitere Informationen sind auffindbar unter: www.uni-potsdam.de/de/umweltpor...

I am so excited to share our new findings with you! We provide the structural evidence for a direct protein-to-DNA information pathway, showing how a bacterial enzyme 'reads' its own structure to 'write' DNA. www.science.org/doi/10.1126/...

Appels and bananas,
clearly

You can't make this shit up

Good results are a blessing and a curse.

Looking forward to showcase our research at the institute of chemistry @unipotsdam.bsky.social next month! 👑

And with this, the bridging hydride arc finally concludes... #RIP

Because is brings the story back to the beginning in 2001 when Fontecilla-Camps et al. suggested a semi-bridging intermediate already. History repeating! However, now we KNOW.

Importantly, the authors provide an explanation for the peculiar "blue shift" of the µCO energy relative to Hox. This might be due to the "semi-bridging" nature of the ligand, which is... funny.

Why?

Room temperature 2D-IR spectroscopy on reduced [FeFe]-hydrogenase now shows that Hred and Hsred do indeed bind µCO ligands, barely detectable by FTIR spectrosopy. Important paper by Birrell & Horch, out in @angewandtechemie.bsky.social
