Long’s Peak framed by rock outcrop, Rocky Mountain National Park, Colorado.
Scientists have long thought most nitrogen in Earth's ecosystems comes from the air, but new research shows it also is released as rocks weather. This could boost plant growth and help sequester carbon – but not fast enough to avert climate change, as some pundits have claimed.
In the field studying the rock association in the Doolena Gap greenstone belt, 30 km north of Marble bar in the Pilbara region of Western Australia.
The remote Pilbara region of Western Australian formed many billions of years ago when the Earth was much hotter and the crust softer than it is today.
Tides are the largest they have been for 250m years.

East Africa Rift is undergoing a process that will see the Horn of Africa split from the rest of the continent.
Through abstraction, the underlying essence of a mathematical concept can be extracted.
An artist’s rendition of the InSight lander - which will collect data on what’s inside the planet Mars.
The InSight Lander mission to Mars is preparing for launch in May 2018. But there are seven (or eight) other planets to explore: why have we such a hang up on Mars?
Seismic shockwaves after a meteorite’s collision could affect systems all over the planet.
Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.
Rising waters: Paris, January 29, 2018.
It was the Seine’s rise and fall, in response to heavy rain, that inspired our current understanding of river systems.
A drying climate caused a mass extinction among plants, but paved the way for the ancestors of modern reptiles, mammals, and birds.
The extinction of dinosaurs is one of the many periods of mass extinctions on earth.
Scientists believe since 2010 we have entered the sixth period of mass extinction. CO2 emissions will change the lives of plants and animals in the next three to four decades.
Fires break out across San Francisco after the April 18, 1906 earthquake.
According to current forecasts, California has a 93 percent chance of an earthquake with magnitude 7 or greater occurring by 2045. Early warning systems, now in development, could limit casualties and damage.
A new study has found a way to predict eruptions at Mount Etna within two weeks.
It turns out that the world is about 4,600,000,000 years old. That’s 4.6 billion years. That’s pretty old!

The world is made of tiny building blocks called 'elements'. Scientists have worked out how fast some elements change into other elements. That gives us a very big clue about how old the Earth is.
As many as 20 people are dead and dozens missing following the Southern California mudslides.

A watershed scientist explains why post-wildfire landscapes are so susceptible to landslides – and why those risks are poised to rise.

In response to mudslides that have killed at least 20 people in Southern California, a geologist calls for more resources to study and map landslide hazards so residents can understand the risks.

'Volcano forensics' involves a mixture of modern day monitoring and analysis of past eruptions. Geologists use volcanic rocks as a kind of time capsule to assess what happened previously.
Where there’s smoke, there will be lava?

How do scientists predict volcanic eruptions? To do so with accuracy, they need to know the individual volcano and its history very well.
The legacy of the dirtiest of fuels – coal – has the potential to deliver a low carbon energy future.
Lynn Margulis receiving the National Science Award from U.S. President Bill Clinton in 1999.
Lynn Margulis (1938-2011) was a courageous scholar whose remarkable work on the role of symbiosis in evolution stands as a magisterial contribution of science.
