In everyday life, continuously doing work on a system is found to heat it up. Rubbing your hands together warms them. Hammering a piece of metal makes it hot. Even without knowing the equations, we learn from experience: driving any system, whether by stirring, pressing, or striking, leads to a rise in the system’s temperature. […]

Researchers have developed a novel way for liquid crystals to retain information about their movement. Using this method could advance technologies like memory devices and sensors, as well as pave the way to future soft materials that are both smart and flexible.
