ScienceDaily: Fossils & Ruins News

In a new study, researchers found that during epochs of extreme heat -- 20 to 30 degrees Fahrenheit hotter than today -- Earth may have experienced cycles of dryness followed by massive rain storms hundreds of miles wide that could dump more than a foot of rain in a matter of hours. The research not only sheds light on Earth's distant past and far-flung future but may also help to understand the climates of exoplanets orbiting distant stars.

Europe's past prosperity and failure, driven by climate changes, has been revealed using thousand-year-old pollen, spores and charcoal particles fossilized in glacial ice. This first analysis of microfossils preserved in European glaciers unveils earlier-than-expected evidence of air pollution and the roots of modern invasive species problems.

They're born. They live once, erupting for a period that might last for days, years or decades. Then, they go dark and die. This narrative describes the life of a monogenetic volcano, a type of volcanic hazard that can pose important dangers despite an ephemeral existence. The landscape of the southwestern U.S. is heavily scarred by past eruptions of such volcanoes, and a new study marks a step toward understanding future risks for the region.

New research could help forensic teams understand whether people or animals were the victims of fatal lightning strikes, based solely upon an analysis of their skeletons.
