When we imagine the sun, we imagine fire, but that isn't really accurate. The sun is plasma; particles so hot that their electrons have boiled off, creating a charged gas that is interwoven with magnetic fields. 

In late September, a 200,000 mile long magnetic filament of solar material erupted on the sun and it ripped through the sun's atmosphere, the corona, leaving behind what looks like a canyon of fire. The glowing canyon traces the channel where magnetic fields held the filament aloft before the explosion. Visualizers at NASA's Goddard Space Flight Center in Greenbelt, Md. combined two days of satellite data to create the short movie below of this gigantic event on the sun.

Blood and bone marrow transplants have been done for decades and have always had risks of complications, like virtually any treatment for serious diseases, but a new study has found an additional one for the list: sexual health.

The Boomerang Nebula is the coldest known object in the Universe; even colder than the faint afterglow of the Big Bang, which is the natural background temperature of space.

Advertising relies on repetition because some repetition increases likability. 

While established brands can coast a little - you never see advertising for Dinty Moore Beef Stew because it is awesome - new brands rely on gaining popularity due to excessive exposure and repetition. 

Less than two weeks in space may be enough to cause profound changes in eye structure and gene expression, according to a new report based on a small study.

The study looked at how low gravity and radiation and oxidative damage impacts mice and examines eye-related gene expression and cell behavior after spaceflight, but the subject size was too limited to be conclusive - 18 mice in nine different condition groups, due to limited aboard orbital missions. 

Over the past three years, 300,000 gamers have helped scientists with genomic research by playing Phylo, an online puzzle game that is a cross between Tetris, Rubik's cube and an old-fashioned sliding-tile puzzle game.

As gamers line up colored rectangles that represent real genetic material (in the form of DNA sequences), they are helping to pinpoint the genetic anomalies that may be the key to a range of diseases that include diabetes, breast cancer and retinoblastoma, the most common form of malignant tumor in the eyes of children.
