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.

Effects of Early-Life Stress on the Brain and Behaviors: Implications of Early Maternal Separation in Rodents

International Journal of Molecular Sciences, 2020
Early-life stress during the prenatal and postnatal periods affects the formation of neural networks that influence brain function throughout life. Previous studies have indicated that maternal separation (MS), a typical rodent model equivalent to early ...

Reconstruction of the first consumer-driven marine ecosystem on Earth, perspectives from early Cambrian small skeletal fossils from China [PDF]

Estonian Journal of Earth Sciences, 2023
Biological activity was the major triggering factor driving Earth’s organic and inorganic cycles across the biosphere, lithosphere, and atmosphere. A key question in the evolution of Earth’s ecosystem is when and how different animals emerged and ...

The Persistent Southern Disadvantage in Us Early Life Mortality, 1965‒2014 [PDF]

, 2020
Background: Recent studies of US adult mortality demonstrate a growing disadvantage among southern states. Few studies have examined long-term trends and geographic patterns in US early life (ages 1 to 24) mortality, ages at which key risk factors and ...

Hyolithid-like hyoliths without helens from the early Cambrian of South China, and their implications for the evolution of hyoliths

BMC Ecology and Evolution, 2022
Background A small hyolith, with a triangular operculum and a conical-pyramidal conch with a sharp apex, originally documented as Ambrolinevitus ventricosus, is revised based on new material from the Chengjiang biota.

The Social Ecology of Childhood and Early Life Adversity

Pediatric Research, 2020
An increasing prevalence of early childhood adversity has reached epidemic proportions, creating a public health crisis. Rather than focusing only on adverse childhood experiences (ACEs) as the main lens for understanding early childhood experiences ...

Branched Setae or Attached Macroalgae: A Case Study of an Exceptionally Preserved Brachiopod from the Early Cambrian Chengjiang Lagerstätte

Biology
The remarkable conservation of soft tissues within Cambrian fossils has significantly enhanced our comprehension of the origins and evolutionary trajectories of animals, in addition to the progression of ecological intricacy.
