Our brain is a ballroom echoing with humming footsteps of exquisite dancers a.k.a 'brain waves'. Synchronised electrical pulses from neurons communicating with each other produce these brain waves that ricochet throughout the brain. They skillfully route information in a way that allows the brain to choose which signals should be considered vital.
Researchers engineer minuscule particles that use light to break down dyes and sense vital chemicals, paving the way for cleaner water and better diagnostics.
