An interesting piece in Universe Today over the weekend takes the dark matter out of the hunt for dark matter, but you’re probably going to want to approach this one carefully--or as Universe Today says, “put on your skeptical goggles and set them to maximum.” An Italian mathematician has done some creative number crunching and accounted for the force that holds galaxies together without the need for dark matter. It’s a bold claim to make--and one that’s going to get a good going-over from physicists.

A team from the University of Western Australia have finished work on a new simulation software package that can accurately predict the sweep of bushfires, and where they're likely to head next.

Japanese Spandex-maker Asahi Kasei Fibers has developed the world's first elastic electrical cable, a stretchy conductive connector that could go a long way toward reducing cord clutter. But it's not just a way to help you manage your multi-cord mess. Called Roboden, the stretchable cord could enable new generations of electronics-embedded textiles and robotic skins.
