Saturn's rings cast a dramatic shadow separating the blues and greens of the planet's northern hemisphere from the creamy pastels coloring the southern hemisphere. This mosaic combines 6 images--2 each of red, green and blue spectral filters--to create this natural color view. The images were obtained with the Cassini spacecraft wide-angle camera on Dec. 30, 2008, at a distance of approximately 750,000 miles from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 30 degrees. Image scale is 42 miles per pixel. (NASA/JPL/Space Science Institute/TNS)

Last Look at Saturn

wo views of a composite reconstruction of the earliest known Homo sapiens fossils from Jebel Irhoud (Morocco) based on micro computed tomographic scans of multiple original fossils. Dated to 300 thousand years ago these early Homo sapiens already have a modern-looking face that falls within the variation of humans living today. However, the archaic-looking virtual imprint of the braincase (blue) indicates that brain shape, and possibly brain function, evolved within the Homo sapiens lineage.

‘The Ultimate Easter Egg Hunt’

by Deborah Netburn Los Angeles TimesApril 9, 2017

In this artist rendering provided by the Florida Museum of Natural History, illustration by Danielle Byerley shows a comparison of a Sifrhippus sandrae, right, with a modern Morgan horse that stands about 5 feet tall at the shoulder and weighs about 1,000 pounds. Global warming often leads to global shrinking for mammals, like us, a new study suggests. At least twice before in Earth’s history, when carbon dioxide levels soared and temperatures spiked, mammals shriveled in a bit in size, including our earliest primate ancestor, according to a new study based on fossil teeth found in Wyoming. And the study’s chief author said it could be a glimpse of a smaller mammal future under even faster man-made warning that’s going on now.
