Watch a Continent-Sized Hurricane Whip Around Saturn's North Pole | Wired Science | Wired.com
Scientists have gotten their first close-up view of the enormous hurricane that has been churning for years at the North Pole of our solar system’s ringed beauty Saturn.
The whirlwind sits at the center of a large and mysterious structure known as Saturn’s hexagon, a polygon-shaped stream whose each side is larger than the entire Earth. Astronomers used NASA’s Cassini spacecraft to fly right over the hexagon and captured the gigantic hurricane within. The eye of the system alone is 2,000 kilometers across, about half the length of Australia or — as Wolfram Alpha kindly points out — a bit bigger than the distance the Proclaimers would walk, just to be the man that walks a thousand miles to fall down at your door.

Warp Drive More Possible Than Thought, Scientists Say | Space.com
HOUSTON — A warp drive to achieve faster-than-light travel — a concept popularized in television's Star Trek — may not be as unrealistic as once thought, scientists say.
A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre; however, subsequent calculations found that such a device would require prohibitive amounts of energy.
New Rocket Fuel Helps NASA 'Go Green' | Space.com
I :bigheart: space.comQuote:
From the rocket launches of the 1970s up to Curiosity Mars Rover last year, spacecraft have used a fuel called hydrazine to propel them through space.
In terms of raw power, hydrazine is highly flammable and throws off an enormous amount of heat. But hydrazine is also highly toxic, both when inhaled and when it makes contact with human skin, and its flammability makes it very difficult to transport and handle.
Lab yeast make evolutionary leap to multicellularity - life - 23 June 2011 - New Scientist
IN JUST a few weeks single-celled yeast have evolved into a multicellular organism, complete with division of labour between cells. This suggests that the evolutionary leap to multicellularity may be a surprisingly small hurdle.
