Saturn’s Rings Could Have Formed when Dinosaurs Walked the Earth

This image is a view from the NASA/ESA Hubble Space Telescope taken on March 22, 2004. Camera exposures in four filters (blue, blue-green, green and red) were combined to form the Hubble image and render colors similar to what the eye would see through a telescope focused on Saturn.

Saturn’s rings are billions of years younger than we thought, say Cornell University researchers analyzing an almost forgotten set of data, collected 10 years ago by NASA’s Cassini mission. This image is a view from the NASA/ESA Hubble Space Telescope taken on March 22, 2004. Camera exposures in four filters (blue, blue-green, green and red) were combined to form the Hubble image and render colors similar to what the eye would see through a telescope...

In the study, whole-brain degree count maps, collected before the start of treatment, were used to identify potential brain regional markers for placebo propensity. Group differences in whole-brain maps for degree count (number of connections of any location to the rest of the brain) between placebo responders and non-responders identified four brain regions that differentiated placebo responders from non-responders. The highest significant difference was seen for the right midfrontal gyrus. Abbreviations: r-MFG - right midfrontal gyrus; ACC - anterior cingulate cortex; PCC - posterior cingulate cortex; r-S2/M1 - right secondary somatosensory and primary motor cortex.
