Common littoral crab (Carcinus maenas)

Crab shell compound makes wounds heal faster

In ancient China crabs were smashed open and thrust into wounds in battles because chitosan is antimicrobial, meaning it heals and kills bacteria.

Chitosan's properties allow it to rapidly clot blood and promote hemostasis (stops bleeding). Chitosan bonds with platelets and red blood cells to form a gel-like clot which seals a bleeding vessel.

GUE Divers Welcomed By BSAC

Leading personnel from the British Sub Aqua Club and Global Underwater Explorers have confirmed a review has been completed on how to integrate GUE divers into BSAC branches.

The useful discussions centred around reinforcing common training features and identifying any mismatches that might cause inconsistencies on branch dives between GUE and BSAC-trained divers.
