Take chemistry, add energy, get life. The first tests of Jeremy England’s provocative origin-of-life hypothesis are in, and they appear to show how order can arise from nothing.
Life was long thought to obey its own set of rules. But as simple systems show signs of lifelike behavior, scientists are arguing about whether this apparent complexity is all a consequence of thermodynamics.
Life might have originated in droplets that behave surprisingly like living cells.
Researchers have discovered that simple “chemically active” droplets grow to the size of cells and spontaneously divide, suggesting they might have evolved into the first living cells.
Insights about time’s arrow from a liquid crystal universe.
What insights can an LCD display give us about time’s arrow?
An RNA molecule that can make copies of a variety of RNAs adds new support to the RNA-world theory.
When life first emerged roughly 4 billion years ago, DNA may have been a much more malleable molecule.
Figuring out how these molecules form in the deep recesses of interstellar space might illuminate the origins of one of life’s distinguishing features.
