A 3D filming technique has revealed that human sperm really swim with a corkscrew motion like otters, rather than wiggling like eels due to their 'wonky tails'. Developed by scientists led from ...

Worms that create intricate, tangled blobs with their bodies can disentangle in milliseconds when threatened. This speedy unscrambling is possible because each worm wriggles in a special corkscrew ...

A team of researchers from Monash University has uncovered how swimming sperm create corkscrew-shaped fluid vortices that help propel them forward, improving their chances of reaching the egg. The ...

Through the microscope lens, van Leeuwenhoek saw it, too: a “small earth-nut with a long tail” that we now know as sperm. After examining some of his own specimens, van Leeuwenhoek asserted that sperm ...

This paper was retracted by Science Advances on May 19, 2021, after readers identified that the described asymmetrical movement of sperm cannot be confirmed using only 3D flagellar waveform data. The ...

Findings published in Nature settle the dispute: phonons can be chiral. This fundamental concept, discovered using circular X-ray light, sees phonons twisting like a corkscrew through quartz.

MANY ANIMALS find safety in herds, colonies, schools or swarms. But few species opt for the technique of the stringy, water-dwelling blackworm Lumbriculus variegatus, a creature that at a few ...
