Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly making it ...

Look up on a clear night and you'll see the streaks of our new space age. What you don't see is the growing fallout for the atmosphere that keeps us alive.

Even when Earth was locked in its most extreme deep freeze, the planet’s climate may not have been as silent and still as once believed. New research from ancient Scottish rocks reveals that during ...

The oceans are the largest entity on Earth’s surface. All that blue, however, may be dwarfed by an immense reservoir of hydrogen concealed in the planet’s heart. Experiments indicate that enough ...

The American Medical Association and a leading public health research group focused on vaccines are teaming up to create a system to review vaccine safety and effectiveness, mirroring a role long ...

Director Pete Browngardt, working from a script by no less than eleven writers, draws inspiration from the original Golden Age 'toons but also recognizes that children schooled on YouTube clips and ...

Life’s story may stretch further back than scientists once thought. Some genes found in nearly every organism today were already duplicated before all life shared a common ancestor. By tracking these ...

The Amazon rainforest is so big that it makes its own climate. As they photosynthesise and transpire, its billions of trees collectively produce enough moisture to form clouds. These, by some ...
