Scientists have long wondered how our Blue Planet came to be covered by 70 percent water. Now a new study offers fresh evidence for how water reached Earth, finding that asteroids and comets are likely rich in water.
Scientists have discovered what are called "dead zones" in the tropical North Atlantic, and they could potentially lead to mass fish kills, according to new research.
It's no secret that climate change is wreaking havoc on our world's oceans, and now new research has shown that it can take marine life millennia to recover from climate change-related upheavals.
Experts are well aware that many of our oceans are running out of oxygen. Sometimes it's a consequence of pollution. Other times we can blame climate change, both man- and nature-driven. However, what is certain is that it's not good for us or the fish and crustaceans that many industries have learned to rely on. Now researchers believe they have found a way to put the oxygen back where it is needed.
Life on Earth supposedly first flourished about two billion years ago, but now a new analysis finds that living organisms actually emerged earlier than scientists previously thought.
If it weren't for iron and fire, we could be a much older species that we are now. Researchers from the Universities of Tübingen and Alberta claim that the heavy metals spewed from subsea volcanoes in Earth's adolescence poisoned early life on earth, delaying a boom in oxygen and life for a half-a-billion years.
Contrary to popular belief, blowfish aren't actually holding their breath when they're puffed up, according to a new study.
The rise of the animals millions of years ago didn't happen sooner due to an oxygen deficiency, according to a new study, letting the air out of one of Earth's nagging mysteries.
Like a scene straight out of "Star Wars," future scuba divers might simply have to slip a thin mask over their face to gain the ability of breathing under water - no oxygen tank required. That's at least one of the dreams fueled by the creation of a new material that can absorb and store massive amounts of oxygen.
New research is suggesting that a certain frequency of sunlight along can convert carbon dioxide into oxygen. However there are many limitations to this process, making it rather useless to Earth. Still, the discovery offers some promising ideas for researchers investigating planet formation and alien worlds.
According to a new study, oxygen-producing organisms were present on Earth some three billion years ago - a full 60 million years earlier than previous estimates had indicated.
Experts have found evidence of ancient pools of water untouched since Earth's earliest years. These primordial oases could provide researchers clues about our planet's earliest forms of life, serving as windows for peering into the dawn of creation.
