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.
French scientists sterilized soil with gamma radiation and sealed it in jars, yet it kept breathing for six years with no living cells inside. The discovery suggests chemistry that may have sparked the first life on Earth is still happening beneath our feet.
NASA scientists discovered that Earth's earliest life forms relied on molybdenum over 3 billion years ago, even though the metal was incredibly scarce. This finding rewrites what we know about how life adapts and what alien worlds might need to support it.
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.
For the first time, researchers have shown how RNA could have copied itself billions of years ago without any help from proteins or enzymes. This breakthrough solves a puzzle that's stumped origin-of-life scientists for decades.
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.
A PhD student in India just recreated mysterious blue spheres that could explain how life began on Earth, reviving the forgotten work of a husband-wife chemistry team from the 1960s. Their groundbreaking discovery might change what we look for when searching for life on other planets.
Scientists in China discovered 700 fossils that push back the origin of complex life by millions of years, revealing our ancient ancestors existed far earlier than we thought. The find bridges a massive gap in our understanding of how life evolved from simple microbes to the incredible diversity we see today.
Scientists found all five DNA and RNA building blocks in samples from asteroid Ryugu, strengthening the idea that space rocks delivered the ingredients for life to early Earth. This discovery brings us closer to understanding how life began on our planet.
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.
The James Webb Space Telescope discovered complex organic molecules in a nearby galaxy that could be the first steps toward life. Scientists found chemicals never before seen outside the Milky Way, revealing how life's ingredients form across the universe.
Scientists recreated space conditions in a lab and watched amino acids spontaneously form complex molecules needed for life. The discovery suggests life's ingredients might form naturally throughout the universe.
Researchers discovered ancient microbes working together in Australia's Shark Bay, revealing how the first complex life may have formed on Earth billions of years ago. The team honored Indigenous Malgana language by naming the microbe after their word for "ancient home."
Scientists in northwestern Canada just discovered fossils that rewrite the timeline of animal evolution, pushing back the origins of complex life by up to 10 million years. These ancient creatures, some 567 million years old, show that the deep ocean may have been the original cradle of animal life.
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 in China discovered 700 fossils that push back the origin of complex life by millions of years. The find suggests the famous "Cambrian Explosion" may have been more of a slow burn than a sudden boom.
After a 26-year hiatus, AFL State of Origin roared back to life with 58,141 fans packing Perth Stadium to watch Victoria defeat Western Australia. Both coaches are now calling for the game to become an annual tradition after witnessing the overwhelming success.
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.
Researchers discovered that life leaves a unique statistical fingerprint in organic molecules, offering a new way to detect alien life without looking for specific compounds. The breakthrough could transform how we search for life on distant worlds.
A spacecraft flying alongside a comet discovered amino acids and phosphorus streaming off its surface, the same chemical ingredients that helped create life on Earth. Scientists captured the first unambiguous proof that comets can carry and preserve these vital molecules through the solar system.
