Light-Induced Non-Reciprocal Magnetism Challenges Traditional Physics

Researchers from Japan have theoretically demonstrated that shining specific light on magnetic metals can induce non-reciprocal magnetic interactions that effectively violate Newton's third law, leading to a novel chiral phase with persistent rotation, opening new avenues in non-equilibrium materials science and potential technological applications.

"Solitons: Time, Space, and Rule Bending"

Researchers from the University of Amsterdam have demonstrated the unique behavior of topological solitons in a robotic metamaterial, showing that they can be harnessed through non-reciprocal interactions to control the movement of robots, sense their surroundings, and communicate. The solitons, which behave like particles but retain their shape and cannot disappear, are being studied for their potential applications in materials science, robotics, and engineering, offering new possibilities for self-propelled motion and advanced functionality.

"Study Unveils Revolutionary Kinetic Asymmetry in Molecular Interactions"

Researchers have discovered a new type of non-reciprocal molecular interaction, termed kinetic asymmetry, which does not require external forces such as hydrodynamics. This phenomenon could redefine our understanding of molecular interactions and has implications for the evolution of life and the design of molecular machines. The study, conducted by scientists from the University of Maine and Penn State, suggests that local gradients of reactants and products around catalysts, like enzymes, can lead to one molecule being repelled by yet attracting another molecule. This insight into kinetic asymmetry could also inform the development of synthetic molecular motors and pumps, offering a deeper understanding of the origins of life and the complex behavior of matter.

"Sperm's Surprising Physics-Defying Feat Stuns Scientists"

Scientists have discovered that sperm and single-celled algae defy Newton's third law of motion due to their non-reciprocal interactions with their surroundings. These microscopic organisms move through viscous fluids using whip-like tails or flagella, which possess an "odd elasticity" that allows them to propel forward without losing much energy to the surrounding fluid. The researchers also introduced a new term, "odd elastic modulus," to describe the internal mechanics of flagella. The findings could have implications for designing self-assembling robots and understanding collective behavior.
