How did life begin on Earth? While scientists have theories, they don't yet fully understand the precise chemical steps that led to biology, or when the first primitive life forms appeared. But what ...

Isolating the first spark of life on Earth is a matter of biology, geology, and chemistry—but it's also an amazing math problem. At least, that's how Varun Varanasi viewed it when he was a Yale ...

Asteroid impacts may have helped kick-start life on Earth by creating hot, chemical-rich environments ideal for early biology. These impact-generated hydrothermal systems could have lasted thousands ...

Long before oceans teemed with life, Earth endured relentless violence. Asteroids slammed into its surface again and again, ...

Isolating the first spark of life on Earth is a matter of biology, geology, and chemistry — but it’s also an amazing math problem. At least, that’s how Varun Varanasi ’24 viewed it when he was a Yale ...

Scientists believe they’ve found evidence that life on Earth is over a billion years older than anyone believed was realistic. New research used machine learning to scan ancient meteorites and fossils ...

The oldest eukaryotes, the ancestors of all complex life on Earth, lived nearly 1.7 billion years ago in shallow, oxygenated marine environments. This is revealed by a new study led by ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

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 ...
