Factors such as sunlight and stage-specific nutrient application determine crop success in urban agriculture, far beyond fixed recipes or miracle solutions. This is demonstrated by an eight-year study conducted by the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB) in its build-integrated rooftop greenhouse, thermally connected to the facility itself, and located within the university campus.

With 302 neurons, 200 of them in their heads, hermaphrodite female roundworms reveal surprising sex-specific differences in the nervous system and how these differences influence behavior, reproduction, and aging. Researchers at Northeastern University compared brain activity in male and hermaphroditic Caenorhabditis elegans, a microscopic worm widely used in biological research to understand how sex wires males and female nervous systems differently.

The fossil had been sitting in a drawer for 100 years, until researchers pulled it out and became curious. Image via Sergey Krasovskiy and Pedro Salas/ Natural History Museum London.
