Polyester microdroplets, possible precursors to life, were formed from alpha-hydroxy acids (αHAs) in early Earth-like conditions even at low reaction volume, low reactant concentrations, and/or high ...

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 ...

About 700 million years ago, Earth was entombed in a veneer of ice hundreds of feet thick—a frozen state scientists refer to ...

Questions about the origin and nature of Earth and the life on it have long preoccupied human thought and the scientific endeavor. Deciphering the planet's history and processes could improve the ...

Japanese researchers uncovered a universal rule describing why life’s growth slows despite abundant nutrients. Their “global constraint principle” integrates classic biological laws to show that ...

April brings us Citizen Science Month and Earth Day—that means it’s the perfect time to get outside, explore nature, and even help real scientists with their research! You don’t need to be an expert, ...

In the Arizona desert, a vast glass structure sits far from cities and farmland. It was built to test an idea that once seemed urgent and uncertain. C.

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting the two factors are linked in some way, researchers say. When you purchase ...
