Early mammals became relatively large-bodied before their teeth evolved the diverse shapes and functions associated with different diets and ecological roles.
Whole-genome sequencing of the Faroese population reveals a unique genetic history shaped by Viking and Celtic ancestry, founder effects, isolation, and adaptation, providing new insight into disease risk and human evolution in the North Atlantic.
Custom hardware and specialised imaging methodology enable direct imaging of collagen through MRI, which could enhance the study and diagnosis of diseases affecting connective tissues.
Autumn timing in temperate deciduous trees is controlled by both developmental stage and seasonal temperature cues, with late-summer cooling overriding earlier developmental differences.
Terrestrial ecosystems in equatorial regions rebounded rapidly after the end-Permian mass extinction, with plants and animals adapting to extreme heat by burrowing and occupying riverine habitats within just two million years.
Using modified rabies virus tracing, researchers show that even a single exposure to addictive drugs can induce long-lasting, cell-type-specific changes in inputs to dopamine neurons.
