[:es]Astronomers have known where the universe’s missing matter has been hiding for the past 20 years. So why did it take so long to find it? [:]

[:es]Cosmologists have predicted the existence of an oscillating signal that could distinguish between cosmic inflation and alternative theories of the universe’s birth. [:]

[:es]Evolution may have coopted an ancient metabolic mechanism to set social insects on the path toward one of the most puzzling behaviors found in nature.[:]

[: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]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.[:]
