Microscopic Swimmers Defy Classical Physics in Viscous Fluids, Research Reveals

Researchers have uncovered how microscopic swimmers like sperm cells navigate through thick fluids while seemingly ignoring fundamental physics principles. The study reveals these biological entities utilize unique elastic properties that create propulsion without equal opposition from their environment. These findings could advance microrobotics and our understanding of collective biological behaviors.

Breaking Physics at Microscopic Scales

Scientists have documented how human sperm and other microscopic biological entities appear to bypass one of physics’ fundamental principles, Newton’s third law of motion, according to recent research. The study, led by mathematical scientist Kenta Ishimoto at Kyoto University, investigated how these tiny swimmers navigate through highly viscous fluids that should theoretically resist their movement.

New Border Policy Requires Airlines to Override ‘X’ Gender Markers on Passports

A new Customs and Border Protection rule directs airlines to disregard ‘X’ gender markers on passports and input ‘M’ or ‘F’ instead. The policy has raised concerns among transgender and non-binary travelers about potential discrimination and travel disruptions during international flights.

New Border Policy Mandates Binary Gender Markers for Airlines

A recent policy change by U.S. Customs and Border Protection is requiring airlines to override “X” gender markers on passports and input either “M” or “F” instead, according to reports. The implementation has created uncertainty and concern among Americans who use the non-binary gender designation on their travel documents.
