The mother of all string theories passes a litmus test that, so far, no other candidate theory of quantum gravity has been able to match.
The rapid, unorthodox emergence of a new finch in the Galápagos hints that speciation isn’t rare. New hybrid species may quietly appear and disappear without anyone noticing.
Updated results from a Japanese neutrino experiment continue to reveal an inconsistency in the way that matter and antimatter behave.
A famously difficult mathematical problem resisted solution for over 40 years. Mathematicians have finally resolved it by following an intuition that links number theory to physics.
To better understand the molecules described by the latest prize in medicine, we will need the technique recognized by the latest prize in chemistry.
New data tracking the movements of millions of Milky Way stars have effectively ruled out the presence of a “dark disk” that could have offered important clues to the mystery of dark matter.
Two new papers urge caution in using powerful genome-editing technology against invasive species: Models show that evolving resistance won't stop aggressive standard gene drives from spreading.
A new version of AlphaGo needed no human instruction to figure out how to clobber the best Go player in the world—itself.
Voevodsky’s friends remember him as constitutionally unable to compromise on the truth—a quality that led him to produce some of the most important mathematics of the 20th century.
Repeating radio bursts are among the most mysterious phenomena in the universe. A new theory explores how some of their puzzling properties can be explained by galactic lenses made of plasma.
The real-world version of the famous “traveling salesman problem” finally gets a good-enough solution.
This year’s Nobel Prize in Chemistry goes to researchers who made it possible to see proteins and other biomolecules at an atomic level of detail.
The American physicists Rainer Weiss, Kip Thorne, and Barry Barish were honored for dreaming up and realizing the experiment that confirmed the existence of gravitational waves.
Three U.S. biologists share the Nobel Prize in Medicine for their research into the molecular mechanism that drives circadian rhythm.
The color of LED lights is controlled by a clumsy process. A new mathematical discovery may make it easier for us to get the hues we want.
“Organoid” brain tissue models grown in a lab for two years can help scientists study a critical period of development just before and after birth.
