This might mean such whales are more intelligent than they have been given credit for. The finding may help explain some of the behaviors seen in whales, such as intricate communication skills, the formation of alliances, cooperation, cultural transmission and tool usage.
Nitric Oxide Reduces Bubble Formation in DiversSunday, December 3rd, 2006
Prevention of bubble formation is a central goal in standard decompression procedures. According to research published in the FASEB Journal, nitric oxide reduces bubble formation following decompression after dives of different duration and to different depths.
In their experiments, the researchers from the University of Split and the Norwegian University of Science and Technology gave divers 0.4 mg of Nitroglycerine by oral spray 30 minutes before a dive. This significantly reduced bubble formation.
Nitroglycerine, best known as an explosive, is converted to nitric oxide in the body.
