A group of Australian divers are changing the world of tankless diving by introducing the AirBuddy. This portable system offers up to 45 minutes of dive time for one diver up to 12 metres of depth and is both lightweight and small; consisting of just a battery-powered air compressor, a regulator and hose. The 12-volt battery takes 3.5 hours to charge using a standard electrical socket.

On his first-ever night dive, Sam, an uncertified and inexperienced diver with fewer than 15 lifetime dives, descended to catch lobsters with two other uncertified divers (Dave and Tim). The three descended, while a fourth diver (Ron) planned to freedive and assist with hauling in the anticipated lobster catch. A fifth diver (Eric) remained on the boat.

Most people understand that human-caused climate change is a real and serious threat. True, some still reject the mountains of evidence amassed by scientists from around the world over many decades, and accepted by every legitimate scientific academy and institution. But as the physical evidence builds daily — from increasingly frequent and intense extreme weather events like droughts and floods to disappearing polar ice to rising sea levels — it takes an incredible amount of denial to claim we have no reason to worry.

A Spanish biologist and amateur beekeeper, Federica Bertocchini, has discovered a plastic-eating caterpillar that could be the solution to global plastic pollution. The caterpillar’s ability to consume plastic was accidentally discovered during routine bee hive maintenance and it’s has since been studied by Bertocchini and her peers at the University of Cambridge. Their findings have been published in Current Biology in April 2017.
