In situ single‐spot Rb/Sr cosmochronology of roedderite in the Ribbeck aubrite (asteroid 2024 BX1)
Abstract The mineralogy and textures of several fragments from the Ribbeck aubrite were analyzed using a combination of scanning electron microscopy, electron microprobe analysis, μRaman spectroscopy, and laser ablation inductively coupled reaction cell mass spectrometry (LA‐ICP‐MS/MS).

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body
Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Aqueous alteration in C2‐ung Bells through the analysis of carbonates – Does a CR origin ring true?
Abstract Bells is an ungrouped carbonaceous chondrite that has in recent years been proposed as a CR‐an. This link to CR chondrites has previously been identified through the analysis of anhydrous silicates, for example, oxygen isotopic compositions of olivine (Marrocchi et al., 2023).

Fascinating single‐cell red algae: models for evolution and adaptation
Summary The unicellular red algae, Cyanidiophyceae, that diverged early during Archaeplastida (algal and plant) evolution, occupy a variety of extreme habitats that are inhospitable for most other eukaryotes. With the use of modern genomics and genetics methods, Cyanidiophyceae show a remarkable taxonomic diversity, share haplodiplophasic life cycles ...

Acceptorless Dehydrogenative Polymerization
Acceptor‐less dehydrogenative polymerization (ADP) enables the atom‐economic step‐growth synthesis of different type of polymers directly from simple alcohols, releasing H2 as the sole by‐product. This review outlines the mechanistic foundations, catalytic systems, and emerging polymer architectures of ADP, highlighting its potential as a sustainable ...
