g ABODES - Researchers have discovered new details surrounding the second-largest mass extinction in Earth's history. The new study shows that a loss of more than 75 percent of species in the world's oceans may have been linked to a cooling climate. See article.
g LIFE - Long-held theories about how dinosaurs became dominant on Earth some 230 million years ago may have to be re-written. A new study shows that when dinosaurs appeared, they may have co-existed with other animals rather than replacing them on the food chain. See article.
g INTELLIGENCE - It would seem that there are striking chronological parallels between significant variations of climate and major historical epochs, such as the Migration Period and the heyday of the Middle Ages. This is the conclusion reached following a study undertaken by researchers from Switzerland, Germany, Austria, and the United States, in which they were able to reconstruct the summer climate in Europe over the last 2,500 years from the information provided by annual tree rings. See article.
g MESSAGE - Here's an interesting paper, "The Temporal Aspect of the Drake Equation and SETI", which critically investigates some evolutionary aspects of the famous Drake equation. Note: This paper is a few years old.
g COSMICUS - Crews have lived on the space station continuously for a decade now. Bringing drinking water to the space station for them is a costly affair, so over the years, NASA has found inventive ways to produce distilled clean water, using everything from ambient station humidity, created by astronauts' breath, to the crew's own urine. See article.
