"Sperm Defies Laws of Physics, Baffling Scientists"

Scientists at Kyoto University have discovered that sperm can defy Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. The researchers found that the flagella on sperm have an "odd elasticity" that allows them to whip around without losing much energy to the fluid, enabling the cells to propel themselves through viscous fluids. This discovery could have implications for designing self-assembling robots and understanding collective behavior.

Sperm Cells Defy Newton's Laws: Scientists Uncover the Mystery

Scientists at Kyoto University have discovered that sperm defy one of Newton's laws of physics by propelling themselves forward through fluid without eliciting an equal and opposite reaction. The sperm's flagella, or tails, change shape to interact with the fluid, allowing them to move without expending much energy. This movement method, known as "odd elasticity," contradicts Newton's law of motion. The researchers used human sperm cells and algae for their study, observing how the flagella deformed and returned to their original shape to propel the swimmers through the liquid.

Sperm's Unusual Elasticity Challenges Newton's Third Law

Researchers at Kyoto University have discovered that sperm and other small organisms are able to bypass Newton's third law of motion by utilizing "odd elasticity." By bending in small ways in response to the liquid they are swimming in, the flagella of sperm cells are able to conserve energy and move through viscous fluids with less effort than expected. This finding sheds light on how tiny creatures are able to navigate through their liquid environments more efficiently.

"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.

Sperm Cells Challenge Newton's Third Law of Motion

Scientists have discovered that sperm and certain microorganisms, such as Chlamydomonas algae, defy Newton's third law of motion by exhibiting non-reciprocal mechanical interactions. These biological swimmers use their flagella to move in a way that elicits no equal and opposite response from their surroundings, thus breaking the law of physics. The cells possess an "odd elasticity" that allows them to wiggle their flagella without expending much energy, enabling them to move forward in a manner that defies physics. Understanding this phenomenon could have implications for designing small elastic robots and studying other organisms capable of non-reciprocal movement.
