Scientists just pushed back the timeline for Earth's first common ancestor by 200 million years, revealing that all life descended from a surprisingly sophisticated microbe that battled viruses in Earth's hellish early days. This tiny organism connects every living thing on the planet, from bacteria to blue whales.
NASA's SPHEREx telescope has mapped water ice throughout one of our galaxy's busiest star-forming regions, revealing how dust shields the building blocks of life from radiation. The findings support theories about how water forms in space and brings scientists closer to understanding the origins of life itself.
Scientists discovered Earth stayed habitable only because oxygen levels hit a perfect sweet spot 4.6 billion years ago. Too much or too little oxygen during planet formation, and life-essential elements would have vanished.
Scientists discovered a 10-billion-year-old star still sitting in its birth galaxy, solving a cosmic mystery about how carbon became the building block of all life. The findings explain why this essential element ended up spread throughout the universe.
Scientists discovered all five building blocks of DNA on asteroid Ryugu, suggesting the ingredients for life might be common throughout our solar system. The findings support the possibility that life's essential components could have arrived on Earth from space.
Scientists just proved that hardy bacteria can survive the crushing forces of asteroid impacts, bringing us closer to understanding whether life on Earth came from space. The findings could reshape how we think about life's origins and where to search for it in the universe.
Researchers discovered ancient microbes in shallow coastal waters that can survive with oxygen, solving a puzzle about how simple life evolved into complex organisms like humans. The finding brings us closer to understanding why plants, animals, and humans exist at all.
New research reveals that ancient microbes called Asgard archaea could use oxygen, finally explaining how complex life emerged. This discovery solves a decades-old mystery about how all plants, animals, and fungi came to exist.
Scientists created a 45-unit RNA molecule that can almost replicate itself, bringing us closer to understanding how life began on Earth. This tiny strand performs both key steps needed for self-replication, just not yet in the same container.
Breakthrough research reveals that individual cells and even molecules display their own form of "selfhood" and decision-making. This discovery could revolutionize medicine and help us understand the very origins of life.
Scientists discovered that the building blocks of proteins can form on frozen space dust before planets even exist, suggesting life's origins may trace back to deep space. This breakthrough shows that complex molecules don't need liquid water to form.
The James Webb Space Telescope discovered what happens when two stars merge in a cosmic explosion called a red nova: they create a supermassive star that spreads carbon compounds essential for life. Scientists found these stellar collisions may have provided the raw materials that made life on Earth possible.
