What if a soft material could move on its own, guided not by electronics or motors, but by the kind of rudimentary chemical signaling that powers the simplest organisms? Researchers at the University ...

During brain development, neurons extend long processes called axons. Axons link different areas of the brain and carry signals within it and to the rest of the body. Growing axons "wire up" the brain ...

The propagation of mechanical deformations along the circular network of beads, which are shown as red, blue, green dots. Chemical waves (shown in magenta) travel in the counter-clockwise direction ...

When plants face stress, they activate a signaling cascade involving multiple molecules like hydrogen peroxide and plant hormones such as salicylic acid, leading to resistance or stress adaptation. It ...

Scientists describe the behavior as "altruistic signalling," a form of social immunity in eusocial insects Getty A new research study finds infected ant pupae emit a chemical signal that prompts ...

Fear has a scent. Here’s how this invisible chemical signal has shaped human perceptions, emotions and survival instincts.
