THE TRUTH ABOUT: Nature geoscience | History Defined

Scientists just found a lost river world buried beneath Antarctica’s ice for 34 million years

Beneath nearly two kilometres of the East Antarctic Ice Sheet, locked away since the continent froze over at least 34 million years ago, scientists have found something that changes the way researchers understand both Antarctica's distant past and its near-term future. Using ice-penetrating radar gathered across multiple airborne survey campaigns,…

In 2013, scientists studying volcanic rocks near Mauritius uncovered ancient zircon clues that revealed a buried microcontinent beneath the Indian Ocean

Scientists have found a piece of ancient Earth's crust hidden in the Indian Ocean. This submerged landmass, called Mauritia, is not a lost continent but a microcontinent. Its discovery was made using tiny minerals and gravity measurements. This finding helps understand how continents break apart. Mauritia reveals secrets of Earth's…

'Dark oxygen' discovery on the seafloor is 'fundamentally at odds with thermodynamics' and should be retracted, experts say

In a recent opinion article, marine scientists and electrochemists listed a number of reasons why it's unlikely that metallic nodules on the deep seafloor could produce oxygen in total darkness.

'Potentially hazardous' asteroid Bennu contains dust older than the solar system itself — and traces of interstellar space

The near-Earth asteroid Bennu contains stardust that is older than the solar system and clues about its violent history, three new studies of the asteroid's sample materials show.

'Quiet Chernobyl' changed Earth's surface so much the planet's mantle is still moving 80 years later

The land beneath the former Aral Sea in Kazakhstan and Uzbekistan is rising and will continue to do so for many decades. Now, scientists have an explanation that involves the sea drying up.

For the first time, robots on Mars found meteorite impact craters by sensing seismic shock waves

Since 2018, NASA’s InSight mission to Mars has recorded seismic waves from more than 1,300 marsquakes in its quest to probe the internal structure of the red planet. The solar panels of the car-sized robotic lander have become caked with Martian dust, and NASA scientists expect it will completely power…

Climate change targets achievable by keeping global emissions to COVID levels, scientists say

Between 2019 and 2020, global CO2 emissions experienced the greatest year-on-year drop in recorded history. Researchers say we have to cut emissions by that much every year to keep climate change within safe boundaries.

World's Glaciers Contain Less Ice than Thought, Report Finds

Advances in satellite technology have revealed that the world's glaciers contain significantly less ice than previously thought, according to a study published in Nature Geoscience on Monday. The revised estimate reduces global sea level rise by 3 inches if all glaciers were to melt. But it raises concern for some…
