An ancient ancestor of spiders and relatives doubled its genome about 400 million years ago, setting the stage for the evolution of spinnerets.

The architecture of the body is not encoded as a formal blueprint; rather, it's the tightly orchestrated activation and ...

Modern neuroscience and the computational modeling of the activities of vast, integrated neural networks provide fruitful accounts of how our minds work and learn.

Ferns switch between male and hermaphrodite forms, a process driven by chemical signals. Research shows the plant hormone auxin is key, triggering new growth centers when a male signal is absent.
