Subliminal Sound to “Cure” Video Game Addiction

A Korean venture start-up claims to have developed an audio sequence that can communicate with addicted game players below the conscious level. The company wants game manufacturers to play the embedded subliminal messages when a young user has kept playing after a preset period of time.
From The Korea Times article:

“We incorporated messages into an acoustic sound wave telling gamers to stop playing. The messages are told 10,000 to 20,000 times per second,” Xtive President Yun Yun-hae said.
“Game users can’t recognize the sounds. But their subconscious is aware of them and the chances are high they will quit playing,” the 35-year-old Yun said. “Tests tell us the sounds work.”

Any scholarly evidence I’ve ever read up on has indicated that subliminal messages don’t work, but apparently marketing such messages is big business.

Xtive applied for a domestic patent for the phonogram and is looking to take advantage of the technology in other sectors.
“We can easily change the messages. In this sense, the potential for this technology is exponential,” Yun said.

Lunar Eclipse

On Saturday and Sunday we, the human population, had an opportunity to see the moon completed blotted out by Earth’s shadow in one of those rare events known as a Lunar eclipse. Personally I’ve always thought solar eclipses to be the more interesting variety and so I never even bothered looking for the moon over the weekend.

However, thanks to the power of modern computing, here is an animated version of the entire phenomena, for those like myself that want all the reward without any of the effort.

I have to admit, the orange glow that appears on the moon during the middle of the action is kind of cool.

Aerogel Photos

Aerogel will be used on the STARDUST spacecraft to capture comet particles from Comet Wild 2. The pics are amazing. They look fake, but they come from the NASA web site.

To collect particles without damaging them, Stardust uses an extraordinary substance called aerogel. This is a silicon-based solid with a porous, sponge-like structure in which 99.8 percent of the volume is empty space. By comparison, aerogel is 1,000 times less dense than glass, which is another silicon-based solid. When a particle hits the aerogel, it buries itself in the material, creating a carrot-shaped track up to 200 times its own length. This slows it down and brings the sample to a relatively gradual stop. Since aerogel is mostly transparent – with a distinctive smoky blue cast – scientists will use these tracks to find the tiny particles.

NASA Altering the true colours Mars Photos Update

It turns out NASA is not Photoshopping pictures of mars, but that, “The answer is that the color chips on the sundial have different colors in the near-infrared range of Pancam filters.”
