Tissue morphogenesis requires tight coordination between biochemical signaling and mechanical forces that sculpt cells and tissues. While actomyosin networks are well-established force generators, microtubule-based mechanics have recently e...

As animals move through the world, images of surfaces and edges in the environment move across the retina, a visual signal known as optic flow.1 Optic flow is beneficial for several processes, perhaps most notably navigation,2 but it poses ...

Secondary cell wall thickening is essential for plant structural development, providing the mechanical strength and rigidity required for upright growth. However, direct observation of this process in its endogenous developmental context wi...

Thermal pollution, whether local or driven by global warming, threatens biodiversity in part through its detrimental effects on reproduction. Non-coding small RNAs (sRNAs) are crucial for maintaining germline developmental robustness under ...

Sexual behavior in mammals is a deeply conserved biological process that integrates evolution, physiology, and neural control. Across species, mating unfolds through coordinated phases of approach, copulation, and post-ejaculatory inhibitio...

Filling important gaps in understanding the mechanisms and evolution of species-specific gamete recognition and fusion, new findings show that a β-propeller-containing protein is essential for gamete recognition in brown algae, and that sp...

Phloem and xylem co-occur in all living vascular plants. A new study on plants from the Rhynie chert, a spectacularly preserved early terrestrial ecosystem, shows that these primary tissues have distinct fossil records exhibiting unique evo...

Animals live in a world of microbes and must distinguish pathogens from benign commensals. A new study shows how animals use enteric neurons to sense components of the bacterial cell wall and how a pathogen-derived molecule blocks this mech...

Understanding the extent of natural selection in human evolution is one of the fundamental questions in human genetics. A new study provides the most comprehensive study to date of natural selection in West Eurasia over the past ten thousan...
