Astronaut Chris Hadfield (previously) reflects on his career, life on the International Space Station, and the challenges of returning home (as well as commercial spaceflight and the film Gravity) in an interview with the Guardian.
A Black Hole Mystery Wrapped in a Firewall Paradox - "A paradox around matter leaking from black holes puts into question various scientific axioms: Either information can be lost; Einstein's principle of equivalence is wrong; or quantum field theory needs fixing." [more inside]
Last fall, the Canadian Space Agency asked students to design a simple science experiment that could be performed in space, using items already available aboard the International Space Station. Today, Commander Chris Hadfield conducted the winner for its designers: two tenth grade students, Kendra Lemke and Meredith Faulkner, in a live feed to their school in Fall River, Nova Scotia. And now, we finally have an answer to the age-old question, What Happens When You Wring Out A Washcloth In Space? [more inside]
Fire tests on the International Space Station are showing some really neat results, including that fire can burn in microgravity at lower temperatures and with less oxygen. Video included at the link. [more inside]
As they leave the solar system, the Pioneer spacecraft have anomalously decelerated, pointing to a possible gap in our understanding of gravity. Now, a computer graphics technique known as Phong shading predicts that the Pioneer anomaly is just a side effect of how the shape of the spacecraft reflects sunlight.
Weightless Cats and other fun experiments. An excerpt from from coverage of research at the Aerospace Medical Division Hq 657Oth Aerospace Medical Research Laboratories including scenes of F-104 seat ejection; drop tests from C-130 and ejection from F-106; effects of weightlessness on cats and pigeons in a C-131; test subjects in water tank, on centrifuge, in heat chamber and on complex coordinator. Also, scenes of vertical deceleration tower, incline impact test facility, vertical accelerator, equilibrium chair and vibration platform.

Friday Flash Fun: Color Theory is a puzzle platformer about... um... color theory. And gravity switching. And aliens. Via the eternal font of pleasant time-wasters, jayisgames.
Maybe the entire universe as we know it really is just sitting inside a black hole of another, bigger universe.
The Space Potty - the one question astronauts get asked most often: "How do you 'go' in space?" [via]
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."
