Summary: Extinction rates are rising, but resources for conservation are limited. Some conservationists suggest prioritizing taxa with phylogenetic and trait-based originality to prevent the loss of evolutionary innovations. A study on a sessile snail species confirmed its originality and called for more attention to the loss of originality in invertebrates.

Summary: Meiotic crossovers are more evenly spaced along chromosomes than expected by chance due to crossover interference. The mechanism behind this phenomenon, which regulates the occurrence of nearby crossover events, remains elusive.

Summary: Cholesterol's ability to uncoil acyl chains of phospholipids has been known for centuries, but the molecular-level understanding of this phenomenon remains elusive. The importance of cholesterol's two-faced character and its role in controlling the fluidity, structure, and functioning of animal cell membranes is highlighted in this Perspective.

Summary: Washingtonia is a genus of palms with two species distributed in Mexico and the United States. The populations show high genetic variation and are structured into four major geographic regions based on phylogenetic analysis. Leaf greenness is identified as a potentially useful morphological trait for identification.

Summary: Regulatory T cells, specifically CD8(+) Tregs, are crucial in maintaining immune balance and preventing autoimmune disorders. The subsets of CD8(+) Tregs, such as CD122(hi)Ly49(+)CD8(+) Tregs, have been identified as non-redundant regulators of germinal center reaction, dependent on factors like Helios, IL-15, TGF-beta, and Eomesodermin. Further research is needed to fully understand the differentiation, function, and true identity of CD8(+) Tregs compared to CD4(+) follicular regulatory T cells in controlling germinal center reaction.

Summary: A novel isopolyoxotungstate has been identified after 30 years since its initial spectroscopic evidence. The heptatungstate [W7O24H](5-) features a stable structure with a fused {W-5} lacunary Lindqvist unit and a ditungstate fragment, being the third isopolytungstate obtained from non-aqueous systems.

Summary: The compound [H7O3](4)[Tc20O68] · 4H2O[1] was prepared from a concentrated Tc2O7 solution over anhydrous H2SO4. The first polyanionic species for technetium, [Tc20O68](4-), was characterized with its unique structure and electronic transitions. X-ray absorption spectroscopy of red HTcO4 solutions provided additional insights into the compound's behavior in aqueous solution.

Summary: Using quantum mechanical calculations, this study explores the limitations of the Schottky emission model for electron injection into dielectrics. The researchers found that the model is only applicable for a small group of dielectrics under specific electric field and temperature conditions. For defective dielectrics with large barrier heights, the electric fields necessary for measurable currents exceed the range of validity for the Schottky emission model. The study provides a quantitative guide to prevent misapplications of the model.

Summary: The taxonomic identities of five-lined skinks of the genus Eutropis inhabiting the Indian subcontinent are re-evaluated. The classification of E. trivittata and E. dissimilis is corrected, and a new synonym E. vertebralis is added. Species Distribution Modelling is used to predict their distribution range and their conservation status is discussed.
