Crash Planning: Mission to Deflect an Asteroid - Space.com  A mission to smash into a space rock to deflect it and study its structure has been given priority over five other potential asteroid projects by the European Space Agency. Scientists don't know enough about asteroid insides to predict how one would respond to attempts to nudge it off an Earth-impact course or turn it into harmless dust. Experts say a regional catastrophe is inevitable in the very long run, over millennia.
Dark Matter and Dark Energy: One and the Same? - Space.com  To explain it all in one fell swoop, Scherrer invokes an exotic form of energy called a scalar field. It's a bit like an electric or magnetic field, with energy and pressure and a magnitude. But a scalar field has no direction. A scalar field is thought to have been behind inflation, the less-than-a-second period after the Big Bang when the universe expanded many billions of times before settling into a more reasonable rate of growth.

Bacteria tested in Mars simulator  - BBC  Danish scientists aim to better understand whether life can survive on Mars by subjecting terrestrial bugs to conditions present on the Red Planet. They are using a "biochamber" to simulate the temperature, radiation and chemical environment found on Mars. "If we see that terrestrial organisms are dead within a couple of months, then it's probably not these types of organisms that we have to look for. "Another important question is: which ecological niches do they live in? From [the Viking landings] we know it's probably not the surface - we probably have to dig down beneath it. "For that, we think it would be very important to know whether you have to dig 20cm into the soil or 20m into the soil." The team is using microbial samples from forest soil outside Aarhus in Denmark and from permafrost obtained in Spitsbergen, Norway.
