Study shows how early Earth kept warm enough to support life
Solving the "faint young sun paradox"—explaining how early Earth was warm and habitable for life beginning more than 3 billion years ago even though the sun was 20 percent dimmer than today—may not be ...
Drilling study finds faults after earthquakes heal faster than previously thought
Research trio claim landslides key to mountain longevity
A stepping-stone for oxygen on Earth: Researchers find evidence of an early manganese-oxidizing photosystem
(Phys.org) —For most terrestrial life on Earth, oxygen is necessary for survival. But the planet's atmosphere did not always contain this life-sustaining substance, and one of science's greatest mysteries ...
Location of upwelling in Earth's mantle discovered to be stable
A study published in Nature today shares the discovery that large-scale upwelling within Earth's mantle mostly occurs in only two places: beneath Africa and the Central Pacific. More importantly, Clinton Conrad ...
Noble gases hitch a ride on hydrous minerals
The noble gases get their collective moniker from their tendency toward snobbishness. The six elements in the family, which includes helium and neon, don't normally bond with other elements and they don't ...
How do you feed 9 billion people?
An international team of scientists has developed crop models to better forecast food production to feed a growing population – projected to reach 9 billion by mid-century – in the face of climate change.
Borneo stalagmites provide new view of abrupt climate events over 100,000 years
A new set of long-term climate records based on cave stalagmites collected from tropical Borneo shows that the western tropical Pacific responded very differently than other regions of the globe to abrupt ...
Life on Earth shockingly comes from out of this world
(Phys.org) —Early Earth was not very hospitable when it came to jump starting life. In fact, new research shows that life on Earth may have come from out of this world.
New rhythm for El Nino discovered
El Niño wreaks havoc across the globe, shifting weather patterns that spawn droughts in some regions and floods in others. The impacts of this tropical Pacific climate phenomenon are well known and documented.
Fracking risks to ground water assessed
One-third of sea level rise comes from melting mountain glaciers, study reports
While 99 percent of Earth's land ice is locked up in the Greenland and Antarctic ice sheets, the remaining ice in the world's glaciers contributed just as much to sea rise as the two ice sheets combined from ...
Billion-year-old water could hold clues to life on Earth and Mars
A UK-Canadian team of scientists has discovered ancient pockets of water, which have been isolated deep underground for billions of years and contain abundant chemicals known to support life.
Earth's center is out of sync
(Phys.org) —We all know that the Earth rotates beneath our feet, but new research from ANU has revealed that the center of the Earth is out of sync with the rest of the planet, frequently speeding up and ...
