Intracellular bound chlorophyll residues identify 1 Gyr-old fossils as eukaryotic algae

Nature Communications, 2022
The authors report nickel-porphyrins derivatives of chlorophyll in ~1 Gyr-old multicellular eukaryotes, preserved in low-grade metamorphic rocks. This brand new approach permits to identify early phototrophic organisms through the geological record.

Paleomagnetic Constraints on the Separation of the Olongbuluke Block From the North China Block During the Late Cambrian–Middle Ordovician and Its Tectonic Significance

Geophysical Research Letters
The collisional evolution of the micro‐blocks in the northeastern Tibetan Plateau is relatively well constrained. However, the reason why a fragment of the North China Block, the Olongbuluke Block, became separated from North China by the Central Qilian ...

Impact of Initial Treatment Setting on Survival in Relapsed Pediatric and AYA Bone Sarcomas: A Secondary Analysis of a Prospective Clinical Trial

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Outcomes in relapsed or refractory pediatric and AYA bone sarcomas remain poor, and the impact of early referral to specialized sarcoma centers on survival is unclear. Early centralization of care may improve local and systemic treatment quality, but evidence in this population is limited.

Recent advances in our understanding of brown and beige adipose tissue: the good fat that keeps you healthy [version 1; referees: 2 approved]

F1000Research, 2018
Brown adipose tissue (BAT) possesses a unique uncoupling protein (UCP1) which, when activated, enables the rapid generation of heat and the oxidation of lipids or glucose or both. It is present in small amounts (~15–350 mL) in adult humans.
