How sulfur helped make Earth habitable before the rise of oxygen

Mapping the bonds and vibrational modes of molecules containing sulfur isotopes is helping to shed light on the chemical reactions that took place in...

A new study shows the evolution and changes of the vegetation...

"Mauritia flexuosa" is the most widespread plant in the Orinoco Delta, in north-western Venezuela. This has not always been the case in the past....

A new study determines the influence of the topography over ...

The emplacement of small-volume (<0,1km3) pyroclastic flows is strongly controlled by topography, according to a new study made by researchers of the Institute of...

New study suggests gigantic masses in Earth’s mantle untouched for more...

Ancient, distinct, continent-sized regions of rocks, isolated since before the collision that created the Moon 4.5 billion years ago, exist hundreds of miles below...

Geochemists measure new composition of Earth’s mantle

What is the chemical composition of the Earth's interior? Because it is impossible to drill more than about ten kilometres deep into the Earth,...

Why is Earth so biologically diverse? Mountains hold the answer

What determines global patterns of biodiversity has been a puzzle for scientists since the days of von Humboldt, Darwin, and Wallace. Yet, despite two...

Earth’s fingerprint hints at finding habitable planets beyond the solar system

Two McGill University astronomers have assembled a "fingerprint" for Earth, which could be used to identify a planet beyond our Solar System capable of...

Meteorite strikes made life on Earth possible

Meteorites from the far reaches of the solar system delivered large amounts of water, carbon and volatile substances to the Earth. Only then could...

A new timeline of Earth’s cataclysmic past

Welcome to the early solar system. Just after the planets formed more than 4.5 billion years ago, our cosmic neighborhood was a chaotic place....

Ancient drop of water rewrites Earth’s history

The remains of a microscopic drop of ancient seawater has assisted in rewriting the history of Earth's evolution when it was used to re-establish...

Earth’s last magnetic field reversal took far longer than once thought

Earth's magnetic field seems steady and true -- reliable enough to navigate by. Yet, largely hidden from daily life, the field drifts, waxes and wanes....

Drilling Deeper : A new study shows Americans are drilling deeper...

Groundwater may be out of sight, but for over 100 million Americans who rely on it for their lives and livelihoods it's anything but...

How a drilling ship pulls cores from 2.5 miles below the...

An ocean drilling ship is not an ocean drilling ship without the skilled and experienced personnel that control, execute and overview the drilling operations....

More ‘reactive’ land surfaces cooled the Earth down

There have been long periods of cooling in Earth's history. Temperatures had already fallen for more than 10 million years before the last ice...

Building blocks of the Earth

Chemical analyses of meteorites allow for a better estimation of the chemical composition of the Earth and its potential building blocks. That is the...

Study provides new insight into origin of Canadian Rockies

The Canadian Rocky Mountains were formed when the North American continent was dragged westward during the closure of an ocean basin off the west...

A family of comets reopens the debate about the origin of...

Where did the Earth's water come from? Although comets, with their icy nuclei, seem like ideal candidates, analyses have so far shown that their...

Formation of the moon brought water to Earth

The Earth is unique in our solar system: It is the only terrestrial planet with a large amount of water and a relatively large...

Ammonium fertilized early life on Earth

A team of international scientists -- including researchers at the University of St. Andrews, Syracuse University and Royal Holloway, University of London -- has...

How Earth’s mantle is like a Jackson Pollock painting

In countless grade-school science textbooks, the Earth's mantle is a yellow-to-orange gradient, a nebulously defined layer between the crust and the core. To geologists, the...
