🦠 Neither plant, animal, nor fungi: protists are beautiful, bizarre, and behaviourally complex.

For @sallywarring.bsky.social and @santa-walker.bsky.social at Earlham Institute, they're creating some fascinating scientific challenges.

What was this year’s Science Ball about for me? Celebrating the friendships and collegiality behind the science at the @viennabiocenter.bsky.social: good vibes, shared laughs, and lots of “sharing is caring”—all in elegant dresses ;-). So here you go: a dance-floor shot capturing that spirit!

The ClaRa retreat V1 was a blast!

The Clausen + Ramundo folks teamed up for two days of science, cooking, and good chaos — plus some skiing ⛷️

Then came the pipetting showdown… and the whale trophy swam home with us 🐋🏆!

Will the @clausenlab.bsky.social win it back next year? Probably 😅 …

@manuelthery.bsky.social and the #CytoMorphoLab reimagined the Musée D’Orsay. Accompanied by an orchestra and poet, their images transported us into the cellular universe. I remembered why I am a cell biologist. All of this is in us. Wow!

Lhcf2 in the peripheral antenna is essential for non-photochemical quenching and Lhcx1 accumulation in the diatom Chaetoceros gracilis
Photosynthetic organisms must continuously balance efficient light harvesting with protection against excess excitation energy, a challenge met by nonphotochemical quenching (NPQ). Although the molecular components involved in NPQ have been extensively studied, how the essential energy-quenching site is assembled remains poorly understood, particularly in marine diatoms. Here, we show that in the centric diatom Chaetoceros gracilis , which belongs to one of the most abundant and diverse genera in marine phytoplankton, the light-harvesting complex protein Lhcf2 is required for energy-dependent NPQ (qE). Targeted knockout of Lhcf2 abolished qE by preventing the stable accumulation of Lhcx1, the canonical NPQ effector in this species. Lhcf2 localizes to the peripheral antenna system and associates with Lhcx1 in a higher-order complex suggested by biochemical and functional analyses. In contrast, other established NPQ-related factors, including the trans-thylakoid proton gradient and the accumulation of diatoxanthin, were not affected by the loss of Lhcf2. These results identify a non-Lhcx-type light-harvesting complex protein as an essential structural component for qE-NPQ and establish a general design principle for the cooperative assembly of photoprotective energy-quenching sites in eukaryotic photosynthesis, with implications for marine carbon fixation. ### Competing Interest Statement The authors have declared no competing interest.
