[: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.[:]

[:es]Lisa Manning, an associate professor of physics at Syracuse University, is widely admired for her success in using insights from physics to explain developmental biology. As she has shown, mathematical […]

[:es]Life needs more than water alone. Recent discoveries suggest that plate tectonics has played a critical role in nourishing life on Earth. The findings carry major consequences for the search […]

[:es]Scientists seek a single description of reality. But modern physics allows for many different descriptions, many equivalent to one another, connected through a vast landscape of mathematical possibility.[:]
