The rise of ‘predatory’ publishing | SciELO in Perspective Over the past two decades, scientific publishing has undergone a technological and economic transformation that has opened the door to more unorthodox models and, unfortunately, predatory practices. P...

🧪In a new blog post, Carmino de Souza discusses predatory publishing: the practice of journals and publishers charging authors high fees, claiming to offer review services that do not exist or are fraudulent, and do not prioritize scientific quality.

YouTube video by Bad Boy of Science The Public Support A New Collider At CERN

A new particle collider at @cern.bsky.social is well motivated scientifically, but is it "too expensive"?

Colliders are publicly funded, so ultimately it's down to the public to decide whether they are willing to pay!

Happily, data suggests they are!

Fig. 3 (shortened full legend in paper) Analysis of Euglena gracilis photosystem II. (A) Quantification of light-harvesting complex (LHC) proteins associated with PSII super-complexes, the PSII core, and free LHCII trimers (LHCII3). (B) Absorption spectra of PSII complexes and LHCII trimers, normalized to their maximum absorbance. (C) Projection maps and structural models of PSII super-complexes as determined by single-particle electron microscopy. (1, 2) Projection maps of two forms of the largest PSII super-complex (C2S2M2L2). (3, 4) Structural models of different forms of the super-complexes obtained by fitting the high-resolution structure of the PSII super-complex from the green alga Chlamydomonas reinhardtii (PDB: 6AKD). (3) The larger form consists of a dimeric PSII core complex (green), minor antenna proteins CP29 (blue), and three pairs of LHCII trimers. (4) The smaller forms lack one L-trimer (red arrow). The reduced density reflects a PSII heterogeneity (see text).

🔆 RESEARCH 🔆

Euglena gracilis has a unique, lineage-specific light-harvesting complex antenna system that dynamically associates with PSII and expands PSI light harvesting, revealing a strategy for light acclimation in secondary plastids - Miranda-Astudillo et al.

A nice piece on GMA about light pollution, dark skies, and the importance of preserving the night sky as much as possible. I've been out to @texasscience.bsky.social's McDonald Observatory and seen the night sky in an area without the light pollution we take for granted, and it's just stunning. 🧪

Even with all the craziness, I've seen many people I know light candles, and speaking from my own experience, it helps me do the same.

Anyway, if you can, maybe this weekend is a good time to light a candle.
