Decompression sickness

Animals exposed to military sonar are thought to develop symptoms similar to decompression sickness. Since microparticles in the blood are known to increase with decompression sickness in diving land animals, researchers explored whether levels were also increased in Steller sea lions (Eumetopias jubatus), that similarly hold their breath while diving. Microparticles are fragments of cell membranes. The…

Life-saving microparticles

Scientists have been able to keep rabbits alive for up to 15 minutes after their windpipes had been blocked by injecting microparticles (yellow in the image below) containing oxygen into their bloodstream.  These microparticles are able to deliver the life-saving oxygen directly to red blood cells allowing the animals to survive with normal blood pressure and heart rates in…
