கார்த்திக் நீலகிரி
Nature never cease to surprise... When they said 'screw you', they actually meant it... நம் முன்னோர்கள் ஒன்றும் முட்டாள்கள் இல்லை...
//We discovered that the sperm tail is in fact wonky and only wiggles on one side. While this should mean the sperm’s one-sided stroke would have it swimming in circles, sperm have found a clever way to adapt and swim forwards: they roll as they swim, much like the way otters corkscrew through water. In this way, the wonky one-sided stroke evens out as sperm rolls allowing it to move forwards.//
//The sperm body spins at the same time that the tail rotates around the swimming direction. Sperm “drills” into the fluid like a spinning top by rotating around itself whilst its tilted axis rotates around the centre. This is known in physics as precession, much like the precession of the equinoxes in our planet.//
Sperms don’t swim — scientists have been wrong for the last 350 years
