We are researching how the cells of leaves on ginkgo trees have changed over time and how we can use this knowledge to learn about the ancient atmosphere of the Earth. Fossil Atmospheres offered ...

Their findings suggest that volcanic activity helped create the perfect conditions for the oxygen-rich atmosphere needed to sustain all life on our planet. Focusing on the late Archean eon (3 billion ...

Ancient microbes illustrate a particular kind of respiration in which carbon dioxide and hydrogen are combined to form acetic ...

A team of scientists from Tohoku University is working to answer that question by exploring how organic matter might have formed in Mars' ancient atmosphere. Organic matter typically comes from ...

This means they are likely to have made up most of the early atmosphere, along with other volcanic gases. Chemical composition of ancient rocks Iron sulfide can only exist in rocks that were ...

Existing explanations about how and when levels of gases changed in the ancient atmosphere are challenged by: Mendeleev left gaps where he predicted that elements, not discovered at the time ...

It traveled 1.9 kilometers (1.2 miles) roughly perpendicular to escarpments thought to be an ancient shoreline from a time—4 billion years ago—when Mars had a thicker atmosphere and a warmer ...

The ancient reactions an MIT chemist is investigating could provide the key to developing new methods that can extract vast amounts of carbon from our atmosphere.

We will use this novel mechanism to quantify climatic and atmospheric change through the Anthropocene and Earth’s ancient past. Demonstrate the utility of fossil micrometeorites as a climate proxy for ...
