Cassini Building A Vast Portfolio Of Differing Views of Titan - SpaceDaily  These three views of Titan from the Cassini spacecraft illustrate how different the same place can look in different wavelengths of light. Cassini's cameras have numerous filters that reveal features above and beneath the shroud of Titan's atmosphere. The first image, a natural color composite, is a combination of images taken through three filters that are sensitive to red, green and violet light. It shows approximately what Titan would look like to the human eye: a hazy orange globe surrounded by a tenuous, bluish haze. The orange color is due to the hydrocarbon particles which make up Titan's atmospheric haze. A single view of this composite is also available here. The second, monochrome view shows what Titan looks like at 938 nanometers, a near-infrared wavelength that allows Cassini to see through the hazy atmosphere and down to the surface. The view was created by combining three separate images taken with this filter, in order to improve the visibility of surface features. The variations in brightness on the surface are real differences in the reflectivity of the materials on Titan. A single view of this composite is also available here. The third view, which is a false-color composite, was created by combining two infrared images (taken at 938 and 889 nanometers) with a visible light image (taken at 420 nanometers). Green represents areas where Cassini is able to see down to the surface. Red represents areas high in Titan's stratosphere where atmospheric methane is absorbing sunlight. Blue along the moon's outer edge represents visible violet wavelengths at which the upper atmosphere and detached hazes are better seen. A single view of this composite is also available here.

Mice in 'suspended animation'  - BBC  Left:  The mice showed no ill effects when they were revived.  Mice have been placed in a state of near suspended animation, raising the possibility that hibernation could one day be induced in humans. The researchers from the University of Washington and the Fred Hutchinson Cancer Research Center in Seattle put the mice in a chamber filled with air laced with 80 parts per million (ppm) of hydrogen sulphide (H2S) - the malodorous gas that gives rotten eggs their stink. During exposure their metabolic rates dropped by an astonishing 90%, and their core body temperatures fell from 37C to as low as 11C.
