A new litmus test for chaos?

July 28, 2015 12:04 pm | by American Institute of Physics | Comments

Does the flap of a butterfly's wings in Brazil set off a tornado in Texas? This intriguing question -- the title of a talk given by MIT meteorologist Edward Lorenz at a 1972 meeting -- has come to embody the popular conception of a chaotic system, one in which a small difference in initial conditions will cascade toward a vastly different outcome in the future...

Lobster-Eye imager detects soft X-ray emissions

July 28, 2015 12:00 pm | by American Institute of Physics | Comments

Solar winds are known for powering dangerous space weather events near Earth, which, in turn, endangers space assets. So a large interdisciplinary group of researchers, led by the U.S. National Aeronautics and Space Administration (NASA) set out to create a wide-field-of-view soft X-ray imager capable of detecting the soft X-ray emissions produced whenever the solar wind encounters neutral gas...

New computer model could explain how simple molecules took first step toward life

July 28, 2015 11:57 am | by DOE/Brookhaven National Laboratory | Comments

Nearly four billion years ago, the earliest precursors of life on Earth emerged. First small, simple molecules, or monomers, banded together to form larger, more complex molecules, or polymers. Then those polymers developed a mechanism that allowed them to self-replicate and pass their structure on to future generations...
