(Nanowerk Spotlight) Imagine a material that doesn’t just respond to one stimulus, like heat or light, but can sense multiple environmental triggers and adjust its behavior accordingly. Picture this ...

Fear learning is a critical feature of survival skills among mammals. In rodents, fear learning manifests itself through direct experience of the aversive event or social transmission of aversive ...

MXenes, a rapidly growing class of two-dimensional transition metal carbides and nitrides, have emerged as powerful building blocks for stimuli-responsive materials (SRMs) owing to their high ...

Our actions are triggered by various internal and external signals (stimuli). These signals may occur from verbal or physical interactions, ongoing or scheduled tasks, urgent requests, reminders, ...

Sleep is generally defined as a period during which the body and mind are at rest—as if disconnected from the world. However, a new study led by Delphine Oudiette, Isabelle Arnulf, and Lionel Naccache ...

The acoustic startle response is an unconditional reflex involving rapid facial and skeletal muscle movements triggered by sudden, startling stimuli like sound or light. Studying the acoustic startle ...

In a new study, researchers were able to predict a person’s response to emotionally charged scenes using brain imaging and computer modeling alone—gauging not only whether the person’s reaction was ...
