Sharks are known for their remarkable ability to heal quickly from wounds. The mucus layer on their skin plays a crucial role in this process. Recent research has uncovered that the mucus layer on shark skin possesses properties that could be beneficial in medical applications, particularly in wound care.

During the DEMA Show in New Orleans, I encountered a dive industry colleague who appeared quite distressed. He had just discovered that a Formula One race was scheduled concurrently with the next DEMA Show in Las Vegas. His concern was that securing a hotel would be impossible, as he believed everything was already booked. At that moment, I was somewhat sceptical of his concern. 

Originally developed for use in pesticides, paints and fire-resistant materials, POPs are highly toxic and do not easily break down in nature. These chemicals have leached into the soil, air and waterways, eventually reaching the ocean. They are absorbed by plankton at the bottom of the food chain and increase in concentration through a process known as biomagnification. As a result, marine mammals, which are at the top of the food chain, accumulate high levels of these toxins.

The fate of coral atolls amidst rising sea levels has been a subject of intense debate and concern. Recent studies and ecological restoration efforts suggest that these unique island formations might have the potential to grow at a rate that could outpace sea level rise, offering a glimmer of hope for their future.
