Bye bye scuba gear...
Divers will soon be able to ditch all that cumbersome scuba gear, replacing it this simple but effective little gadget. This device is effectively a set of artificial gills that extract the oxygen from water through hundreds of tiny holes - bringing us as close to fish as we can manage without costly surgery and gene manipulation!
The great thing is the tech will eventually be usable in other situations too - firefighters, aircraft emergencies and for military situations where access to oxygen is a "very important thing".
