Four billion years ago, Earth was violent, hot, and unstable. Yet new research suggests that by then, life had already reached a surprising level of complexity. At that time lived the last universal ...

A split-second stall at the start of genes may explain how complex animals evolved, according to the Cornell Chronicle. Researchers found that a brief “pause” in gene activity grew stronger and more ...

Would you rather fight a horse-sized duck or 100 duck-sized horses? The famous question, though implausible, reflects a ...

Updated models suggest only 60,000 to 250,000 Earth-like habitats may exist in the Galaxy, with far fewer capable of ...

Humans have it. So does Drosophila. But not yeast. That "it" is a small pause at the start of gene activity—a brief molecular halt that may have helped life evolve from simple cells to complex animals ...

The researchers think the pattern they observed in ants reflects a more universal trend in the evolution of societal ...

Ocean hypoxia and microplastics are interconnected crises, intensifying each other and threatening marine ecosystems and ...

At the microscopic edge of biology, researchers have uncovered an organism so stripped down that it forces a rethink of what ...

Autophagy is the cellular equivalent of a housekeeping system. When operating correctly, it eliminates damaged proteins, ...
