Earth May Have Had A Ring System 466 Million Years Ago
In a discovery that challenges our understanding of Earth’s ancient history, researchers have found evidence suggesting that Earth may have had a ring system, which formed around 466 million years […]
![An unrooted maximum-likelihood phylogenetic tree of the catalytic subunit (HydA) of [FeFe] hydrogenases and the hybrid hydrogenases. The tree was constructed based on 3,677 amino acid sequences using the LG + C20 + R + F model. The numbers at the branches indicate the aLRT (approximate likelihood ratio test) and ultrafast bootstrap (within bracket) support values, each with 1,000 replicates. The scale bar corresponds to the expected number of substitutions per site. Colored circles at the tip indicate sequences from eukaryotes and major archaeal groups. All other sequences are from bacteria. -- Cell](https://i0.wp.com/astrobiology.com/wp-content/uploads/2024/06/How-Archaea-The-Third.png?resize=1200%2C720&ssl=1)

How Archaea, The Third Form Of Earth Life, Makes Energy
An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas.

World First Study Sheds Light On Why Microbes In The Deep Ocean Live Without Sunlight
A world first study reverses the idea that the bulk of life in the ocean is fuelled by photosynthesis via sunshine, revealing that many ocean microbes in fact get their […]
