The Pacific Northwest has seen below-normal snow this season — and new research from Portland State University suggests that the region's snowmelt-dependent water resources could face growing challenges in the years ahead as forest fires and winter rainstorms become more frequent.

Researchers have created the first map of a network of subglacial lakes in the Canadian Arctic showing 33 bodies of water under glaciers.

Using a decade of ArcticDEM satellite data of the Earth’s surface height, a team of researchers including the University of Waterloo developed a method that allowed them to track the draining and filling of active subglacial lakes in unprecedented detail.

A newly discovered fossil site in southwest China has transformed our understanding of how complex animal life emerged on Earth, revealing that many key animal groups had already evolved before the start of the Cambrian Period. The study, led by researchers at Oxford University’s Museum of Natural History and Department of Earth Sciences as well as Yunnan University in China, has been published today (02 April) in Science.
