In what way is this a breakthrough? Is it due to the recorded proof of the brain at work? If not, how in the past, did anyone assume that the brain filtered information without processing it? Doesn't it need to be judged to determine its importance, even subconsciously?

The article says that his paper "challenges currently accepted models about how the brain processes visual information."

Sun Set To 'Flip Upside Down' Within Weeks
The Sun's magnetic field is expected to flip upside down within weeks as its north and south poles swap sides.
The phenomenon, which will send "ripple effects" throughout the solar system, happens once every 11 years as the solar cycle reaches its peak.
It will be observed throughout the heliosphere - the vast region of space affected by the Sun's magnetic field, which extends billions of miles beyond Pluto.
The swap could cause intergalactic weather events such as geomagnetic storms, which can cause radio blackouts and interfere with satellites.
The heightened solar activity it coincides with is also expected to give stargazers a better glimpse of the aurora borealis, or Northern Lights.
Todd Hoeksema, a scientist at Stanford University's Wilcox Solar Observatory, said the polar reversal takes place as the Sun's magnetic field moves north or south from the equator, eroding the existing pole as it does so.
"It's kind of like a tide coming in or going out," he said. "Each little wave brings a little more water in, and eventually you get to the full reversal."
Latest measurements show the Sun technically has two south poles, caused by its two hemispheres being out of sync.
Phil Scherrer, who works with Mr Hoeksema at the observatory, said: "The north pole has already changed sign, while the south pole is racing to catch up.
"Soon, however, both poles will be reversed, and the second half of solar max will be under way."
Mr Hoeksema said in early August that a "complete field reversal" looked like being "no more than three to four months away".
Instruments at the solar observatory near San Francisco have been staring at the Sun for nearly 40 years and record its magnetic field every day.

There ain't no difference between a flying saucer and a time machine. People get so hung up on specifics they miss out on seeing the whole thing. Take South America for example. South America, thousands of people go missing every year. Nobody knows where they go, they just, like, disappear. But if you think about it for a minute, you realize something. There had to be a time when there was no people, right? Well where did all these people come from, huh? I'll tell you where. The future. And where did all these people disappear to? [Otto: The past?] That's right! And how did they get there? Flying saucers. Which are really…? Yeah, you got it… time machines. I think a lot about this kind of stuff on the bus. That's how come I don't drive.

Stuxnet's Secret Twin - By Ralph Langner | Foreign Policy
Stuxnet is not really one weapon, but two. The vast majority of the attention has been paid to Stuxnet's smaller and simpler attack routine -- the one that changes the speeds of the rotors in a centrifuge, which is used to enrich uranium. But the second and "forgotten" routine is about an order of magnitude more complex and stealthy. It qualifies as a nightmare for those who understand industrial control system security. And strangely, this more sophisticated attack came first. The simpler, more familiar routine followed only years later -- and was discovered in comparatively short order.
