Neuroscientist Jill Taylor describes her experience with a stroke.

One of the few known oscillating chemical reactions, it can generally repeat itself about 10 times before ending as a dark blue liquid smelling of iodine.

A reversed-polarity sunspot was detected today, marking solar minimum and the beginning of the 24th solar cycle (since humans first recorded the undulating pattern of solar intensity nearly 400 years ago).

“If it works, the HTV-3X will be the first reusable scramjet-powered plane. It will be able to take off from a runway, fly at speeds of up to Mach 6, land safely, and then do it again.”

Put a bunch of humans on a tiny ship on a 6 month trip to Mars and, you can imagine. Astronauts need to do it like anyone else, especially if the mission counts on their mental and physical well-being.

There’s a high-res version of the above collage that makes the detail in the bottom-most view of Europa really stunning. Images recently reprocessed by Ted Stryk from original Galileo telemetry.

“Where forward thinking terrestrials share ideas and information about the state of the species, their planet and the universe, living the lives of science fiction.”

Nevermind that the fork and spoon are balanced perfectly so as to be their own counterbalance. Watch how the flame extinguishes at the fulcrum, and how the ash curls away from the center of gravity.

His explanation traces the seemingly erratic nature of fundamental particles to the symmetries of E8, a simplified representation of an even more complex 248-dimensional object. “My brain exploded with the implications and the beauty of the thing,” he told New Scientist, recalling when he first made the connection between his theories and the shape of E8. “I thought: ‘Holy crap, that’s it!’” Thus far all the particle interactions predicted by his model correspond with observations in the real world.
