3D images of sharks’ spiraled intestines reveal they work like Nikola Tesla’s one-way valve to permit fluid to solely circulation in a single path with out backflow

  • Scientists created 3D images of shark intestines from 22 completely different species
  • They discovered the spiraled organs gradual the motion of meals because it strikes to the intestine
  • It additionally pushes the meals downward in a approach that doesn’t permit it to maneuver up
  • That is much like Nikola Tesla’s one-way valve that solely lets fluid transfer in a single path, with out backflow or help from any transferring components 

How sharks eat has been a thriller among the many scientific neighborhood, however a brand new examine reveals the apex predators’ intestines work simply like famed inventor Nikola Tesla’s one-way valve.

By creating 3D images of intestines from 22 shark species, reminiscent of spiny and easy dogfish sharks, at group of scientists led by California State College discovered the spiral-shaped organs gradual the motion of meals and direct it downward by means of the intestine – a whole course of that depends solely on gravity.

That is much like Tesla’s innovation that permits fluid to circulation in one direction, with out backflow or help from any transferring components.

The findings additionally reveal a shark’s intestines permits the enormous fish to retain meals longer, which is why it may well go days with out consuming.

For hundreds of years, scientists have solely had sketches of sharks’ digestive system to assist them piece collectively how the organs  perform.

However the newest examine, revealed in Proceedings of the Royal Society, integrated fashionable expertise to lastly uncover the thriller. 

The group used a a computerized tomography (CT) scanner to create 3D images of shark intestines from preserved specimens.

This methodology allowed scientists to gather info with out having to dissect the sharks.  

This is similar to Tesla's innovation that allows fluid to flow in one direction, without backflow or assistance from any moving parts. Pictured is a sketch of Tesla's valve

The findings also reveal a shark's intestines allows the giant fish to retain food longer, which is why it can go days without eating. Pictured is the intestines of a Pacific spiny dogfish shark

Adam Summers, a professor primarily based at College of Washington Friday Harbor Labs and co-author of the examine, stated in a statement: ‘CT scanning is one of the one methods to know the form of shark intestines in three dimensions.

‘Intestines are so complicated — with so many overlapping layers, that dissection destroys the context and connectivity of the tissue.

‘It might be like making an attempt to know what was reported in a newspaper by taking scissors to a rolled-up copy. The story simply will not cling collectively.’

The scientists plan to create fashions of a number of completely different shark intestines utilizing a 3D printer, which is able to permit them to see how supplies transfer by means of the organs in actual time.

And it ought to function in the identical approach as Tesla’s one-way valve.

Tesla patented his one-way valve in 1920, which has similarities to conventional valves however with out transferring components.  

It has a design that permits fluid to circulation unimpeded in a single path, however within the different path, the fluid is blocked.

Tesla gave the next rationalization in his patent: ‘The inside of the conduit is supplied with enlargements, recesses, projections, baffles, or buckets which, whereas providing just about no resistance to the passage of the fluid in a single path, apart from floor friction, represent an virtually impassable barrier to its circulation within the reverse [direction].’
