Paleoclimate Cycles as Analogs for Present Day Warming

Paleoclimate Cycles as Analogs for Present Day Warming | Geology | Scoop.it
Guest Post By Renee Hannon Abstract Detailed pattern correlation of Earth's temperature changes during the past 450 kyrs reveals observations about several cyclic climate patterns. The past four glacial cycles are increasing in duration from 89 kyrs to 119 kyrs. Within these glacial cycles, two warm periods occur about 200 kyrs apart and have strikingly…

Supercomputing helps researchers understand Earth's interior: Geologists create model with potential to predict earthquakes, volcanoes, and other tectonic activity

Supercomputing helps researchers understand Earth's interior: Geologists create model with potential to predict earthquakes, volcanoes, and other tectonic activity | Geology | Scoop.it
Geologists have created a computer model of tectonic activity so effective that they believe it has potential to predict where earthquakes and volcanoes will occur. Scientists focused on the deep mantle and its relationship to plate tectonics.

Ancient Peru: Major discovery of early human life: Elaborate baskets reveal sophisticated societies in the late pleistocene and early Holocene ages

Ancient Peru: Major discovery of early human life: Elaborate baskets reveal sophisticated societies in the late pleistocene and early Holocene ages | Geology | Scoop.it
A-tisket, a-tasket. You can tell a lot from a basket. Especially if it's from ancient ruins of a civilization inhabited by humans 15,000 years ago. An archeologist is among the team who made a groundbreaking discovery in coastal Peru -- home to one of the earliest pyramids in South America. Thousands of artifacts, including elaborate hand-woven baskets, show that early humans in that region were a lot more advanced than originally thought and had very complex social networks.

If you have to smash your head all the time, you’d hope that your body had some mechanism to prevent your brain from rattling out. Knock that noggin around enough, and eventually (on evolutionary scales, that is), you might end up looking, well, very silly.

What bone proteomics could reveal about the dead

What bone proteomics could reveal about the dead | Geology | Scoop.it
Studying bones has helped scientists reconstruct what dinosaurs and other extinct creatures looked like. Taking this further, scientists recently started identifying proteins from bones to glean more information about remains. But one team has found that the reliability of this approach can depend on which bone is analyzed. Additionally, they report a forensic use for bone proteomics: potentially determining from bone proteins how old someone was when they died.

History of Titan's landscape resembles that of Mars, not Earth: Rivers on three worlds tell different tales

History of Titan's landscape resembles that of Mars, not Earth: Rivers on three worlds tell different tales | Geology | Scoop.it
In a paper published in Science, researchers report that Titan, like Mars but unlike Earth, has not undergone any active plate tectonics in its recent past. The upheaval of mountains by plate tectonics deflects the paths that rivers take. The team found that this telltale signature was missing from river networks on Mars and Titan.
