Using a modified version of the Stanford marshmallow test, researchers at the Marine Biological Laboratory (The University of Chicago) discovered that cuttlefish had the ability to delay gratification for a better reward—and those that were able to do it for a longer duration possessed better cognitive learning abilities.
The findings, which demonstrated the link between self-control and intelligence, was published recently in the Proceedings of the Royal Society B journal.
There are currently about half a trillion corals in the Pacific. Of the species studied, two-thirds of the coral species have population sizes exceeding 100 million colonies, while 20 percent of the species have population sizes that are more than a billion colonies.
“We need to know the abundance of a species to assess its risk of extinction,” said lead author Andy Dietzel from the ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE at JCU).
I’d like to nominate, Deborah Braham, a friend I made on a diving trip to Tobago.
Deborah is an NHS anaesthetist and early on when PPE was in short supply, she just went on WhatsApp and organised visors and more directly for her hospital. Deborah just made it happen.
Deborah married another diver not long after we met. With her in the UK and us in Switzerland, we haven’t managed to meet up since she had children. Whatever, in Yorkshire speak, she’s a “lovely lass” who definitely deserves a good holiday.
This finding was based on research by a team of biologists and mathematicians from Swansea University and the University of Essex. It involved 15 three-spined stickleback fish observed individually in a fish tank containing two, three or five plants in fixed positions.
Fourth Element - the UK-based thermal protection manufacturer - came up with the idea in April 2020 with the aim of lifting divers' spirits, whilst they remained at home during the first British Government lockdown.
The idea was simple. Take the best photo you can underwater in your bathtub. And if you don't have a bath, just get creative. A sink, bucket, water butt or just about anything that can hold water was perfectly acceptable.
For 40 years, DAN has protected divers against the risks associated with dive injuries. With this experience we have gained an intimate understanding of what can and doesgo wrong — for travelers as well as divers.
Available to U.S. residents, DAN’s new travel insurance plans offer coverage for events including trip cancellations, missed connections, illnesses and injuries, baggage delays — and even qualifying COVID-19-related cancellations and interruptions.
Until recently, the geographic wanderings of the whitespotted eagle ray have always been a mystery.
Now, in a study that took place from 2016 to 2018, a team of researchers have started to unlock some of its movement patterns.
The 54 rays in the study were tagged with acoustic transmitters, along both the Gulf of Mexico and the Atlantic coast of Florida, using collaborative acoustic telemetry networks.
Who are the Top 10 Scuba Diving Pioneers? It doesn't matter if you're a cave diver, wreck diver, deep diver, or none of the above. If Scuba Diving is your passion/profession, you owe a debt of gratitude to the pioneers that came before you, those that shaped the industry.
In this video, GUE diver Nico Lurot is going to count down the TOP 10 Scuba Diving Pioneers whom he believes had (some of) the biggest influences on the industry and sport we love.
A BDSG spokesman states "Although we are currently in lockdown, it is time to start preparing to scuba dive UK sites and seas. We are all very keen to get back in the water again.
We understand that everyone is heartily sick of COVID-19 rules, hence this is an appeal for divers to do the right thing, and behave accordingly. Please take into consideration the following guidelines as you get set to scuba."
Divers need to comply with relevant medical requirements, and medicals may have lapsed, so check your dates. There is now the added complication of any impact COVID-19 may have created. Your respiratory system can be affected by the Coronavirus and can have long term effects that could impact on your ability to dive safely. If you have any doubts, seek professional medical advice from a diving doctor.
For those unfamiliar with this training agency, the qualification is the highest GUE closed-circuit rebreather (CCR) rating, ie advanced Trimix.
This means that John Kendall is able to teach both GUE's CCR courses: CCR Diver Level 1 and CCR Diver Level 2. John now joins the nine other GUE instructors in the world, capable of teaching this course.
Currently there are only 10 GUE CCR2 instructors in the world. Global Underwater Explorers

Four of the six baleen whale species found in the western North Atlantic Ocean (humpback, sei, fin and blue) have changed their distribution patterns in the past decade.
Using 281 passive acoustic recorders moored to the sea floor from the Caribbean Sea to Greenland, researchers from the United States and Canada monitored the movements of the whales from 2004 to 2014. The findings of their study was published in the Global Change Biology journal.
