Scientists have created miniature magnetic swimming devices – which mimic the appearance of sperm cells – that could revolutionise disease treatment by swimming drugs to specific areas of the body.
A study published in the Journal of Cell Biology focuses on the development of the sperm tail, the structure that enables sperm cells to swim and is therefore critical for male fertility.
Scientists at the University of York have shown that a sperm tail utilizes interconnected elastic springs to transmit mechanical information to distant parts of the tail, helping it to bend and ultimately swim toward an egg.
Sperm tails are actually complex propellant and navigational devices that help push them through fluids and navigate around complex terrain of the female oviduct. Now researchers at Yale and Harvard Universities have identified ...
Just like workers in a factory, enzymes can create a final product more efficiently if they are stuck together in one place and pass the raw material from enzyme to enzyme, assembly line-style. That's according to scientists ...
Spermatozoa need to crane their necks to turn right to counteract a left-turning drive caused by the rotation of their tails, new research has found.
Vanderbilt biologists have discovered that mosquito sperm have a "sense of smell" and that some of same chemicals that the mosquito can smell cause the sperm to swim harder.
