We Just Found The Largest Luminous Glowing Shark Species in The World


We Just Found The Largest Luminous Glowing Shark Species in The World
3 MARCH 2021
Three species of shark that inhabit the twilit depths of the ocean just turned out to have been bioluminescent this whole time.
The kitefin shark, the blackbelly lanternshark, and the southern lanternshark have all been discovered to have softly glowing blue patterns on their skin, a first for sharks found in New Zealand waters.
 
Of those three, the kitefin shark, which grows up to 180 centimetres (5 feet 11 inches) long, is now the largest known bioluminescent shark in the world.
Bioluminescence is not an uncommon trait for living things to evolve. Even humans glow (although too faintly to actually see). It seems to be most useful for life forms that live in the dark - night-glowing fungus, insects in dark caves… and in the depths of the ocean, so deep that the rays of the Sun can t penetrate the water. ....

Water influences stickiness of Hyaluronan


Sylvie Roke, Head of Laboratory for fundamental BioPhotonics © 2020 Alain Herzog
Hyaluronic acid, also known as hyaluronan, is a polysaccharide that helps establish the viscosity of bodily fluids. According to a new study by EPFL scientists, it also influences the behavior of far more water molecules than previously thought. Their findings – just published in Science Advances – open new avenues of research on the role water plays in the human body.
While water has long been known as a crucial component of biological systems, it is only recently that scientists are beginning to discover the intricate ways in which it drives the structuring of biological compounds such as proteins, membranes, DNA and sugars That is also the case for hyaluronan, a polysaccharide found around cells and in parts of our body where lubrification and viscosity are important, like in our joints. Hyaluronan is a key determinant of the texture of the aqueous fluids in these areas. Using a new me ....
