The amount of energy infusing empty space seems too small to explain without a multiverse. But physicists have at least one alternative left to explore.
A newfound pair of giant viruses have massive genomes and the most complete resources for building proteins ever seen in the viral world. They have refreshed the debate about the origins of these parasites.
Even with no one in charge, army ants work collectively to build bridges out of their bodies. New research reveals the simple rules that lead to such complex group behavior.
Modelers find evidence that a combination of competition, predation, and evolution will push ecosystems toward species diversity anywhere in the universe.
Stimulating part of the cortex as needed during learning tasks improves later recall. The finding reveals more about the brain’s memory network and points toward possible therapies.
Mechanical tension between tethered cells cues developing tissues to fold. Researchers can now program synthetic tissue to make coils, cubes and rippling plates.
The Navier-Stokes equations describe simple, everyday phenomena, like water flowing from a garden hose, yet they provide a million-dollar mathematical challenge.
Compact genomes and tiny cells gave flowering plants an edge over competing flora. This discovery hints at a broader evolutionary principle.
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.
