Two-Stroke Motion: "This new illusion won second place at the recent international 'Illusion of the Year' competition at the annual European Conference on Visual Perception, A Coruna, Spain.
What is it?
The illusion contains two pattern frames depicting a moving image (hence two-stroke) which are displayed using a technique that creates an impression of continuous forward movement. Any two frames from a motion sequence can be used. The two images below show two views of a motorcycle as it advances along the road."

Fanged frogs among 40 new species in PNG crater: "A LOST world populated by fanged frogs, grunting fish and tiny bear-like creatures has been discovered in a remote volcanic crater on Papua New Guinea.
A team of scientists from Britain, the US, Hawaii and Papua New Guinea found more than 40 previously unidentified species when they climbed into the kilometre-deep crater of Mount Bosavi and explored a pristine jungle habitat teeming with life that has evolved in isolation since the volcano last erupted 200,000 years ago."

Random Thoughts: Cymothoa exigua: Alien!: "Cymothoa exigua is a parasitic crustacean of the family Cymothoidae. This parasite attaches itself at the base of the tongue of the Spotted rose snapper, Lutjanus guttatus, with the claws on its front three pairs of legs, and extracts blood. As the parasite grows, less and less blood is able to reach the tongue, and eventually the organ atrophies from lack of blood. The parasite then replaces the fish's tongue with its own body, by attaching to the muscles of the tongue stub."
