Cereals from the Fertile Crescent and broomcorn millet from northern China spread across the ancient world, integrating into complex farming systems that used crop-rotation cycles enabled by the different ecological regions of origin. The resulting productivity allowed for demographic expansions and imperial formation in Europe and Asia. In this study, scientists illustrate that people moved […]
Researchers have identified a benign tumor found in a fossilized dinosaur tail as part of the pathology of LCH (Langerhans cell histiocytosis), a rare and sometimes painful disease that still afflicts humans, particularly children under the age of 10.
An analysis of the so called climate spectrum shows why the ice ages have not behaved precisely as the models predict. A large element of coincidence is involved when an ice age begins or ends, the analysis shows. The results imply we should maybe use a more conservative risk assessment then the one IPCC recommends.
This new work sheds fresh light on the complicated interplay of factors affecting global climate and the carbon cycle -- and on what transpired millions of years ago to spark two of the most devastating extinction events in Earth's history.
An emerging scientific consensus is that gases -- in particular carbon gases -- released by volcanic eruptions millions of years ago contributed to some of Earth's greatest mass extinctions. But new research suggests that that's not the entire story.
Sometimes I feel like we are not worried enough about how acidic the ocean is becoming. Did you know there are times in the geologic record where there is absolutely no coral? It can happen. https://news.agu.org/press-release/warming-acidic-oceans-may-nearly-eliminate-coral-reef-habitats-by-2100/#.XkqvgvoYnZI.twitter
@AndyFarke I've been denied access to study specimens (or even obtain photographs!) that were published on, with description, almost 20 years ago. They've sat, in the researcher's treasure chest, for years without any study at all.
