February Geology media highlights
The Geological Society of America's February issue of GEOLOGY contains a number of newsworthy items including new estimates of K-T impact dust that show it did not cause mass extinctions, a hypothesis about rare jellyfish fossils in Wisconsin, evidence from East Greenland fossil leaves of atmospheric carbon dioxide levels during the last (Eemian) interglacial, and two articles from different groups of geologists studying the Indian Vindhyan Supergroup that come to similar conclusions.

After serious head injury, survivors may still be able to learn without awareness, via different brain structures
