It's nothing to lose sleep over — really, I promise — but Earth's atmosphere is leaking oxygen. Atmospheric oxygen levels have dropped by 0.7 per cent over the past 800,000 years, and while scientists aren't sure why, they're rather excited about it.

Buried inside ancient grains of rock salt, a team of geologists has discovered traces of a breathable, animal-friendly atmosphere. If confirmed, the finding will push back the rise of oxygen on Earth hundreds of millions of years, raising new questions about the evolution of complex life both here and beyond our solar system.
A team of scientists in Denmark have invented a crystalline material that can absorb oxygen with astounding efficiency. How astounding? Well, a single spoonful of the stuff can suck all of the oxygen out of a room. The best part is that it can release it again with just a little bit of heat. Say goodbye to bulky oxygen tanks.
Who knew such extraordinary altitudes could be found, hidden inside the towers of Manhattan's Flatiron District? But, behind the nondescript door of a fifth floor office on 21st St, heights as great as the Himalayas are waiting to be scaled. Gizmodo took a deep breath and visited the atmospheric wizardry of Hypoxico, makers of high-altitude training facilities for professional sports teams and the world's top endurance athletes.
All the cool kids know that playing with fire is totally awesome, but there's only so much you can accomplish with the tools available to your everyday pyromaniac. Scientists can have a bit more fun, and this slow-motion video of liquid oxygen tossing around a chunk of flaming charcoal is a great chance to live vicariously.
This may seem like something out of a science fiction movie: researchers have designed microparticles that can be injected directly into the bloodstream to quickly oxygenate your body, even if you can't breathe anymore. It's one of the best medical breakthroughs in recent years, and one that could save millions of lives every year.
The volatile mix of seawater and melting fuel rods is producing hydrogen and oxygen gas - the stuff that blew the lids off Fukushima twice last month. To avert another disastrous hydrogen explosion, workers are blowing intert nitorgen gas inside.
This is a very niche product for a) those who want to move overseas with their dogs or b) Mariah Carey. Who knew dogs needed additional oxygen supplies when flying at altitudes above 2000m?
Chances are, as a kiddywink, you looked up to your mum or dad and asked "why is the sky blue?" Just in case you've forgotten, or your parents told you a whopping fib, io9 has come to the rescue.
