Mysterious New 'Dark Flow' Discovered in Space. "As if the mysteries of dark matter and dark energy weren't vexing enough, another baffling cosmic puzzle has been discovered. Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon 'dark flow.' The stuff that's pulling this matter must be outside the observable universe, researchers conclude." [more inside]

I drink my tea with chopsticks. At least, I would if I lived in outer space. Cool movie (achtung: Quicktime) from the international space station showing the effects of surface tension in the absence of gravity. I wonder if any of us will ever live long enough to experience this in person?

The Mars Gravity Biosatellite Project is an unmatched international effort that pools top-notch technical talent from MIT, the University of Washington in Seattle, and the University of Queensland in Brisbane, Australia. The mission is nothing short of groundbreaking. The plan is to build a spacecraft capable of housing a small crew of mice, including pregnant females, which will simulate the gravity of Mars to determine its effects on mammalian development.

A small world in most dimensions: "University of Washington scientists using gravity measurements to hunt for evidence of dimensions in addition to those already known have found that those dimensions would have to occupy a space smaller than 0.2 millimeter."
