How life began on earth: modeling Earth’s ancient atmosphere

The key to unlocking the secrets of distant planets starts right here on Earth. Researchers at Tohoku University, the University of Tokyo, and Hokkaido University have developed a model considering various atmospheric chemical reactions to estimate how the atmosphere — and the first signs of life — evolved on Earth. “Ancient Earth was nothing like … Read more

Modeling study shows that marshes provide cost-effective coastal protection

Credit: Pixabay/CC0 Public Domain Images of coastal houses being carried off into the sea due to eroding coastlines and powerful storm surges are becoming more commonplace as climate change brings a rising sea level coupled with more powerful storms. In the U.S. alone, coastal storms caused $165 billion in losses in 2022. Now, a study … Read more
