Elon Musk says SpaceX’s Starship could become one of the most important milestones in the evolution of life, arguing the ...

There are "costs of life" that mechanical physics cannot calculate. A clear example is the energy required to keep specific ...

For decades, scientists assumed that life on Earth emerged through a chain of highly improbable flukes. But a new theory suggests it may have instead arrived just in time. When you purchase through ...

For decades, many scientists have relied on the "hard steps" model to suggest that intelligent life is rare — the improbable result of a series of unlikely evolutionary leaps. But new research by ...

Geerat Vermeij's latest book explores a new approach to thinking about the evolution of life through the accumulation of 'power,' defined as the ability of organisms to take up or expend energy. (UC ...

Giant DNA viruses that infect eukaryotic cells are thought to have played a role in the evolution of life, according to the ...

Yet modern biology has revealed that cells are preternaturally sophisticated assemblages — literally automated, miniaturized factories. How could the evidence have been overwhelming but now orthodoxy ...

Paleontologists who study earth’s ancient fossil record might not seem to be the obvious choice when asking about the prevalence of intelligent life in the cosmos. But paleontology, the study of ...

Chris Impey receives funding from the National Science Foundation and the Howard Hughes Medical Institute. We have only one example of biology forming in the universe – life on Earth. But what if life ...

Researchers have identified microstructures in fossil cells that are 1.75 billion years old. These structures, called thylakoid membranes, are the oldest ever discovered. They push back the fossil ...
