Explore the 13.8 billion year history of our Universe compressed into a single calendar year. This video covers key events, ...

Nearly three-fourths of Earth is covered by oceans, making the planet look like a pale blue dot from space. But Japanese researchers have made a compelling case that Earth's oceans were once green, in ...

CAMBRIDGE, MA -- During photosynthesis, an enzyme called rubisco catalyzes a key reaction — the incorporation of carbon dioxide into organic compounds to create sugars. However, rubisco, which is ...

Salk researchers have discovered how some plant species evolved a more efficient photosynthesis approach; findings could help make staple crops including rice and wheat more resilient to climate ...
