Quanta

[:es]A controversial new paper argues that universes with dark energy profiles like ours do not exist in the “landscape” of universes allowed by string theory[:]

[:es]What’s easy for a computer to do, and what’s almost impossible? Those questions form the core of computational complexity. We present a map of the landscape.[:]

[:es]Researchers explore a loophole that extracts useful energy from a fluid’s seemingly random motion. The secret? Sugar and asymmetry.[:]

[:es]After researchers found a loophole in a famous experiment designed to prove that quantum objects don’t have intrinsic properties, three experimental groups quickly sewed the loophole shut. The episode closes […]

[:es]Water-bearing minerals reveal that Earth’s mantle could hold more water than all its oceans. Researchers now ask: Where did it all come from?[:]

[:es]A controversial theory suggests that perception, motor control, memory and other brain functions all depend on comparisons between ongoing actual experiences and the brain’s modeled expectations.[:]

[:es]Astronomers suspect that there’s a large planet hiding out in the distant fringes of the solar system. At a recent workshop, they brainstormed ways to coax it into view. [:]

[:es]By squeezing fluids into flat sheets, researchers can get a handle on the strange ways that turbulence feeds energy into a system instead of eating it away.[:]

[:es]The more closely geneticists look at complex traits and diseases, the harder it gets to find active genes that don’t influence them.[:]
