Soil that has been irradiated to kill all microbial life continues to emit CO2 and generate free electrons, suggesting that metabolic processes are occurring geochemically, outside of cells. These abiotic metabolic reactions might have had a role in the origin of life.

The Dirt That Refused To Die | Quanta Magazine

Lifelike biochemistry continued to unfold in sterilized soil for six years, pointing to a metabolic theory for how biology began.

In today’s oceans, “marine snow” refers to drifting aggregates of tiny particles.
But what if something similar existed before life began?

This preprint explores the idea that such aggregates could have served as small shuttles, gathering molecules, carrying them across environments.

What if life did not emerge from one universal environment—but from a mosaic of distinct environmental structures?
Hydrothermal vents may have been only one node in a distributed landscape of early metabolic roles.

Dying Stars Replicated, Shedding Light on Life's Origins

Scientists in a lab recreated dying stars, showing how hydrogen helps create cosmic dust with the building blocks for life. This could explain how life started on Earth.

Researchers have successfully made cosmic dust in a lab, similar to what dying stars produce. This dust contains the basic ingredients for life, showing they might have come from space.

Scientists just discovered something surprising about the earliest life on Earth 🌍🔬

Ancient organisms, over 3 billion years ago, were already using rare metals like molybdenum and even tungsten to power essential life processes 🤯

What’s shocking? These elements were extremely scarce at the time… yet life still found a way to use them.

This discovery is changing how scientists think about the origin of life and even how we search for life on other planets 🌌

Earliest Organisms on Earth Built Their Biochemistry around Molybdenum, Study Suggests | Sci.News

New research reveals that 3.7 to 3.3 billion years ago (Archean Eon), ancient microbes relied on molybdenum -- a metal that was vanishingly rare at the time -- and even experimented with tungsten.
