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 of years—long enough for life’s building blocks to form.

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 undergraduate.

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Here’s what you’ll learn when you read this story: Life on Earth had to begin somewhere, and scientists think that “somewhere” is LUCA—or the Last ...

In Beacon Valley, one of the most Mars-like regions on Earth, Ariel Waldman reveals hidden ecosystems that persist despite extreme conditions. From nematodes navigating salty permafrost to endoliths sheltering within sandstone and hypoliths thriving beneath translucent rocks,
