Researchers are building a case that long before the nervous system works, the brain sends crucial bioelectric signals to guide the growth of embryonic tissues.
Two teams of researchers have made significant progress toward proving the black hole stability conjecture, a critical mathematical test of Einstein’s theory of general relativity.
An unlikely team offers a controversial hypothesis about what enabled animal life to get more complex during the Cambrian explosion.
A recently proposed experiment would confirm that gravity is a quantum force.
The long, variable times that some diseases incubate after infection defies simple explanation. An idealized model of tumor growth offers a statistical solution.
The latest artificial intelligence systems start from zero knowledge of a game and grow to world-beating in a matter of hours. But researchers are struggling to apply these systems beyond the arcade.
A new study challenges one of the most celebrated and controversial ideas in network science.
New algorithms show how swarms of very simple robots can be made to work together as a group.
Cosmologists have shown that it’s theoretically possible for a contracting universe to bounce and expand. The new work resuscitates an old idea that directly challenges the Big Bang theory of cosmic origins.
