Why African countries must invest more in earth sciences

It seems the production of Earth science knowledge in Africa is simply not progressing, despite the world’s interest in (and exploitation of) the continent’s mineral wealth.

Ancient sponges or just algae? New research overturns chemical evidence for the earliest animals

Ancient fatty molecules, once believed to be traces of some of the first animals to live on Earth, may have been produced by algae instead.

Marie Tharp pioneered mapping the bottom of the ocean 6 decades ago – scientists are still learning about Earth’s last frontier

Born on July 30, 1920, geologist and cartographer Tharp changed scientific thinking about what lay at the bottom of the ocean – not a featureless flat, but rugged and varied terrain.
Earth is really ancient, and humans have only been around for a tiny part of that time. NASA

Curious Kids: how was the Earth made?

All the buildings and the cars and the restaurants, and the phones and even everything that’s inside of you… it all started with an exploding star, billions of years ago.

Deep sea carbon reservoirs once superheated the Earth – could it happen again?

Thousands of years ago, carbon gases trapped on the seafloor escaped, causing drastic warming that helped end the last ice age. A scientist says climate change could cause this process to repeat.

Scientists have been drilling into the ocean floor for 50 years – here’s what they’ve found so far

The ocean floor holds unique information about Earth’s history. Scientific ocean drilling, which started 50 years ago, has yielded insights into climate change, geohazards and the key conditions for life.
