Artificial cells that reproduce without biology
Researchers used simple molecules to create cell-like bubbles that grow and divide on their own, without the need for DNA or enzymes.

How molecules copy themselves with fewer errors
Researchers found a new way molecules self-replicate with fewer errors, by selecting similar ingredients. This “selective binding”…
A new treasure trove of Cambrian fossils
Paleontologists discovered a new set of fossils from the ancient ancestors of animals in rocks from China.
How complex plants reshaped the oceans
Researchers found that when complex plants evolved, they increased ocean oxygen and massively restructured the marine ecosystem.
How did humans learn to speak?
Scientists compared parts of the brain that correlate to speech in humans and primates to understand how speech evolved in humans.
Fig trees interbreed more at their climate extremes
Scientists tracked how fig trees interbreed and swap DNA across different climatic zones to determine where new species might arise.
Intelligent life might be rare
How hard is it for evolution to produce intelligent life like humans? We don't really know, but some computational modelers tried to answer…
Which came first, the cysteine or the egg?
Scientists used to think cysteine was required to manufacture itself. Turns out, it isn't. In fact, cysteine slows down the manufacture of…
Oxygen, nitrogen, and what happens when biology gets involved
When studying Earth’s past, researchers want to understand how nutrients like nitrogen cycled and the impact biology had on them.…
Can you teach an old gene new tricks?
Evolution explains how living things change over successive generations, giving rise to diversity. Across the evolutionary history of Earth,…
