Chapel Hill -- University of North Carolina at Chapel Hill scientists have discovered the human version of a gene and gene product that is an essential component of the tiny hair-like whips called ...

Countless tiny hairs (cilia) are found on the outer wall of some cells, for example in our lungs or in our brain. When these micrometer-sized hairs coordinate their movement and produce wave-like ...

Axonemes are molecular machines that enable the movement of cilia, the hair-like structures found on the surface of some cells. Atomic models of axonemes from the flagella of green algae and from the ...

Cygb is a heme-containing globin protein that is not involved with oxygen transport or storage, unlike its pentacoordinate relatives, myoglobin and hemoglobin. Nevertheless, Cygb contains a ...

Little is understood about how cilia, the tiny hairlike organelles that in humans are often the first lines of defense against pathogens in our lungs and respiratory tracks and even help push sperm ...

The microscopic, hair-like structures called cilia act like the engines of cellular biology. They use a coordinated wave motion to propel bacteria, clean out your lungs and even move eggs from the ...

Researchers have now designed a micro-sized artificial cilial system using platinum-based components that can control the movement of fluids at such a scale. The technology could someday enable ...

New research has identified the mechanism by which air pollution damages the lungs’ self-cleaning system, leaving us vulnerable to infection. In doing so, it has also identified a way to reverse that ...

Man has been breathing with lungs for a million years. Men have been studying the lungs’s physiology for nearly 5.000 years. But not until Radiologist Alfred Ernest Barclay* took to blowing bismuth ...
