Earth's mantle is made of solid rock that nonetheless circulates slowly over millions of years. Some geologists assume that this slow circulation would have wiped away any geochemical traces of Earth's early history long ago. But a new study led by University of Maryland geologists has found new evidence that could date back more than 4.5 billion years.
Quinoa, the sacred ‘mother grain’ of the ancient Inca civilization suppressed by Spanish conquistadors, could become an increasingly important food source in the future thanks to genetic secrets revealed in a new study.
Researchers have isolated 80 million-year-old collagen peptides in the lab. The collagens were found in fossilized tissue attached to the femur of a Brachylophosaurus canadensis, a type of mid-sized hadrosaur.
Have you ever spotted something unexpected while walking down the street? Last December, paleontologists literally stumbled upon a new discovery of a fossil sea cow in a very unexpected place — in a limestone paving stone in Spain! Research presented this week at the Society of Vertebrate Paleontology meeting in Salt Lake City, Utah, describes this remarkable find and how it is changing our understanding of sea cow evolution.
