Duck-billed dinosaurs: Evolutionary bursts led to weird and wonderful head crests

Called the 'sheep of the Mesozoic'as they filled the landscape in the Late Cretaceous period, hadrosaurs walked on their hind legs and were known for their powerful jaws with multiple rows of extremely effective teeth. They also had hugely varied head display crests that signalled which species each belonged to

Ayahuasca fixings found in 1,000-year-old bundle in the Andes: New evidence that the mind-blowing brew goes back millennia

The discovery adds to a growing body of evidence of ritualistic psychotropic plant use going back millennia, said Miller, a postdoctoral fellow at the University of Otago in New Zealand who conducted the research during her doctoral studies at UC Berkeley.

Nature's dangerous decline 'unprecedented,' species extinction rates 'accelerating'

Why you love coffee and beer

Scientist Marilyn Cornelis searched for variations in our taste genes that could explain our beverage preferences, because understanding those preferences could indicate ways to intervene in people's diets. To Cornelis' surprise, her new Northwestern Medicine study showed taste preferences for bitter or sweet beverages aren't based on variations in our

Arctic warming will accelerate climate change and impact global economy

A new paper in Nature Communications reveals a combination of these factors has the potential to increase the long-term economic impact of climate change by just under $70 trillion, under mitigation levels consistent with current national pledges to cut carbon emissions (5% of the estimated total cost of climate change

An evolutionary rescue in polluted waters: How genetics, resources and a long-distant relative helped one lucky fish species adapt to extreme pollution

The exceptional survivor story of the Gulf killifish was one scientists at the University of California, Davis, Baylor University and their co-authoring colleagues wanted to unveil so they could learn more about what other species may need to adapt to drastically changed environments. The minnow-like Gulf killifish are an important
