Sperm can “defy the laws of physics”, according to new research. The laws of motion have helped us to comprehend the behaviours of the natural world for centuries, but sperm appears to go against one of the laws set down by Isaac Newton. Kenta Ishimoto and his fellow mathematical scientists from Kyoto University have revealed new research which suggests that sperm actually display qualities which don't follow Newton’s third law of motion. Science enthusiasts will know that the third law states that “for every action, there is an equal and opposite reaction”. However, sperm seems to go against this. According to their research, the tails of sperm known as “flagella” have an “odd elastic” quality which makes them able to travel through viscous fluids without losing much energy. While scientists would normally expect them to be slowed down by the viscous fluids, they’re able to propel themselves forward much easier than researchers would have predicted – and seemingly avoid coming into contact with an equal and opposite reaction. "From solvable simple models to biological flagellar waveforms for Chlamydomonas and sperm cells, we studied the odd-bending modulus to decipher the nonlocal, nonreciprocal inner interactions within the material,” the team behind the study said. "Odd elasticity is not a generic term for activity in solids, but rather a well-defined physical mechanism that generates active forces in solids or in other systems in which a generalized elasticity can be defined without using an elastic potential."

Scientists have detected huge waves in outer space that measure three times the size of our sun. The waves are being formed on a star system called MACHO 80.7443.1718, found around 169,000 light-years from Earth in the Large Magellanic Cloud. The waves are formed in a similar way to waves on Earth. Just like ones on our planet are formed due to the gravitational pull of the moon, a nearby celestial object stretches the star and causes enormous waves in the system MACHO 80.7443.1718. Experts have studied the star’s unusual behaviour and published a paper in the journal Nature Astronomy. The experts stated that MACHO 80.7443.1718 contains a "heartbreak" star, which is a term they use to describe the way plasma is influenced by the pull of a nearby object to unleash incredible waves of energy. The sheer power of these waves is, itself, difficult to imagine. In fact, just one of them would end life on Earth in an instant. "Each crash of the star’s towering tidal waves releases enough energy to disintegrate our entire planet several hundred times over," MacLeod said. "This heartbreak star could just be the first of a growing class of astronomical objects," MacLeod added. "We’re already planning a search for more heartbreak stars, looking for the glowing atmospheres flung off by their breaking waves." The scale in general is far beyond human comprehension – at least ours, anyway. In fact, the waves of plasma measure around 2.5 million miles above the surface of the primary star – which itself has a radius of 10.4 million miles, around 24 times the size of the sun.
