Stereo Images

The instructions to make this work are to stare at the left image with your right eye and the right image with your left eye and, as a result, the images will appear to "drift" into a single 3D image. Personally I just sort of "will it" into correct focus. There are more images on the Source 1 page.

This is also applied to computer-generated data (see the Source 2 page for instructions on how to set these up). The Source 2 site has many suggestions for how to trick your eyes into seeing the images in 3D. Headaches are free of charge.

Mind Games and Giant Fungus

Source: National Geographic Snagged from fugaciouslover. Prototaxites stood more than 8 metres tall, and flourished between 420 and 370 million years ago with fossils being found around the world. A recent study may have finally identified what this organism was... a giant fungus.

Source: National Geographic New simulations have led scientists to the conclusion that global warming may reduce, rather than increase, the strength of hurricanes. The key is that a rise in ocean temperature will also increase wind shear which inhibits hurricane formation. What they have yet to discover his how wind shear and hurricane formation interact to generate the storms we observe. Without this knowledge, it is impossible to accurately predict the rate of hurricane formation as the Earth's temperature rises.

When the average person makes a mistake, the anterior cingulate cortex generates a pulse a few milliseconds after the mistake is recognized. This pulse, called the ERN (Error-Related Negativity) is noticeably subdued in people impulsive and antisocial disorders. It should be noted that all the participants in the study were average, healthy university students; however, those with subdued ERNs were more impulse than average, just not to a degree that reduced their ability to function within society. The researchers theorize that reduced ERN generation may be at the heart of pathologies related to poor impulse control.

The company demonstrated a game in which users must concentrate to keep a light sabre active. The device reads the EEG signals they generate while performing the task and compare them to baseline EEG levels related to concentration, relaxation, and anxiety.

They are looking at using television signals to augment GPS in situations where the position of the television transmitter and time of transmission is known.
