Publication from Humboldt fellow Carlos Baiz on authorship best practices

Dr. Carlos Baiz from the University of Texas at Austin received the prestigious Humboldt Fellowship for Experienced Researchers from the Alexander Von Humboldt Foundation, enabling him to conduct research at the Freie Universität Berlin. He spent the latter half of 2022 collaborating with SFB speaker Joachim Heberle and colleagues, contributing his infrared spectroscopy knowledge to the development of new imaging techniques such as nano-infrared (nano-IR) spectroscopy.  Last week, he  published a paper  in the Biophysical Journal suggesting an improved approach to authorship in biophysics publications. He argues that as the field of biophysics grows and becomes increasingly collaborative, the traditional practices to evaluate authorship should be reviewed and revised. He suggests the development of definitive guidelines which will hopefully make navigating the challenges of determining authorship easier, such as data ownership. He also discusses the evaluation of authorship order.

2 SFB Publications in Nature about Photosystem II

Postdoc and former IGK member Rana Hussein, together with PIs Athina Zouni and Holger Dobbek (project A5), have published a paper in Nature elucidating the mechanisms underlying the formation of oxygen during photosynthesis, a mechanism also examined by IGK member Paul Greife and PI Holger Dau (project A4) in a second Nature publication. Together, their work not only deepens our understanding of protein function but paves the way for the clean production of storable energy with artificial photosynthesis via water-splitting processes.

SFB Publications by Brünig et al (TP C1, Netz) analyze excess-proton spectra beyond the normal-mode scenario

In a recent publication in Nature Communications, Brünig et al. show how the infrared spectroscopic signatures of hydrochloric acid solutions are related to proton-transfer processes between water molecules, the elementary step of the long-range Grotthus transport. In a second work that just appeared in the Journal of Chemical Physics, the IR band shapes produced by proton-transfer events are derived using analytical models for the barrier-crossing dynamics as a proton moves from one water molecule to a neighbouring one.

Joachim Heberle co-organises well-known Heraeus Workshop on Advanced Microscopy and Spectroscopy methods

In this seminar, we bring together leading experts in modern, evolving fields such as super-resolution microscopy, near-field microscopy and in-cell spectroscopy with colleagues from medicine to discuss latest advances in biophysical techniques and their possible application to medical questions. Challenges remaining for translation into routine procedures will be discussed.

SFB Publication in Nature Communications

Together with colleagues, SFB 1078 PIs Peter Hegemann (TP B2), Han Sun (TP C8), Ulrike Alexiev (TP A2), and Peter Hildebrandt (B6) and their coworkers shed new light on the molecular basis of fluorescence in microbial rhodopsins named QuasArs and their peculiar voltage sensitivity using a combination of spectroscopic studies and molecular dynamics simulations which reveal a unique photoreaction scheme and voltage-dependent changes of the hydrogen-bonding networks. The results pave the way for the development of next generation voltage sensors for optogenetics applications and were recently published in the September issue of Nature Communications.

SFB Publication by Patricia Saura and Ville Kaila (SFB 1078 Mercator fellow) in PNAS

In this recent publication in PNAS, Saura et al. show that internal redox changes in C c O create orientated electric fields that sort the protons along the chemical and pumping pathways, while preventing back leakage reactions.

New algae rhodopsin published in Nature Structural & Molecular Biology

The SFB 1078 PIs Igor Schapiro (C6) and Peter Hegeman (B2) were involved in the discovery, structure and biophysical characterization of bestrhodopsins, a microbial rhodopsin subfamily from marine unicellular algae, in which one rhodopsin domain of eight transmembrane helices or, more often, two such domains in tandem, are C-terminally fused to a bestrophin channel.

SFB Publication in Nature Chemistry

In a joint publication by SFB 1078 colleagues from six different subprojects, a combination of quantum mechanics/molecular mechanics calculations and ultrafast visible and infrared spectroscopies demonstrates how proton-coupled dynamics in the excited state of Pfr leads to a restructured hydrogen-bond environment of early Lumi-F, which is interpreted as a trigger for downstream protein structural changes.

Joint Science Publication by J. Heberle and I. Schapiro

A brand-new publication by SFB 1078 PIs and colleagues from Switzerland proposes the ion transfer pathway in bacterial halorhodopsin and discusses the interplay between the driving force created by the protein dipole moment and the control of transport by molecular gates. Furthermore, the authors provide details of how light energy is converted into kinetic energy for chloride translocation. The resulting charge separation represents a fundamental feature for light energy conversion in nature as well as in technology: Mous et al. 2022. Dynamics and mechanism of a light-driven chloride pump. Science (3 Feb 2022) , DOI: 10.1126/science.abj6663

Han Sun is appointed as a W2 professor at the TU Berlin

We congratulate Dr. Han Sun for being appointed a W2-S professor at the Institute of Chemistry of the Technical University of Berlin. As PI of the SFB 1078 project C8 she aims to obtain a comprehensive picture of proton and cation permeation in several viroporins such as the M proteins of the Dengue and West Nile viruses that pose high biomedical threats. She is also involved in other projects that can assist drug discovery.
