Scientists have discovered the cause for an observed slowdown in the Walker Circulation (WC) over the past 60 years, and in the process boosted their confidence in atmospheric models. The WC is a wind pattern in the tropical Pacific that, as it changes from year to year, spawns floods and droughts in North America and…

A spiky, well-armored mollusk that lived in the ocean 390 million years ago has been brought back to life with the help of 3-D printers. To reassemble the specimen, a team led by Jakob Vinther, a postdoctoral fellow at the Jackson School, made a three-dimensional model of the fossil using a technology similar to medical…

Researchers from Harvard University, The University of Texas at Austin and elsewhere have found evidence that the evolution of birds is the result of a drastic change in how dinosaurs developed. Scientists have long understood that modern birds descended from dinosaurs. Rather than take years to reach sexual maturity, as many dinosaurs did, birds sped…

A team of American and Chinese researchers has revealed the detailed feather pattern and color of Microraptor, a pigeon-sized, four-winged dinosaur that lived about 120 million years ago. A new specimen shows the dinosaur had a glossy iridescent sheen and that its tail was narrow and adorned with a pair of streamer feathers, suggesting the…

Archaeopteryx had (some) black feathers

A team of scientists announced the first evidence of feather color in Archaeopteryx, a feathered dinosaur that has also long been considered one of the earliest birds. The first fossil remains, consisting of a single feather, were discovered in 1861. It’s this single feather that was analyzed using a technique developed by Jakob Vinther, a…
