Faced with a navigational challenge, neural networks spontaneously evolved units resembling the grid cells that help living animals find their way.
A roundup of some of the most important discoveries gleaned so far from the Gaia space observatory’s new map of the galaxy.
Zeta values seem to connect distant geometric worlds. In a new proof, mathematicians finally explain why.
To date the branches on the evolutionary tree of life, researchers are looking at horizontal gene transfers among ancient microorganisms, which once seemed only to muddle the record.
A recent experiment shows how quantum mechanics can make heat flow from a cold body to a hot one, an apparent (though not real) violation of the second law of thermodynamics.
Paradoxically, a small galaxy that seems to contain none of the invisible stuff known as “dark matter” may help prove that it exists.
Using a brain-computer interface, scientists are beginning to learn why learning is hard.
A simple, step-by-step breakdown of two “perfect” math proofs.
For decades, researchers have commonly assumed that higher oxygen levels led to the sudden diversification of animal life 540 million years ago. But one iconoclast argues the opposite: that new animal behaviors raised oxygen levels and remade the environment.
