Graduate student Kurt Rademaker struck anthropological gold last summer. High in the Peruvian Andes, he discovered prehistoric quarries of obsidian, the volcanic glass used in toolmaking. His discovery could be the key to understanding how humans settled South America.   To access the complete UMaine Today Magazine article, please visit the following website: UMaine Today […]

A team led by University of Maine scientists has reported finding a potential link between changes in solar activity and the Earth’s climate.  In a paper for the Annals of Glaciology, Paul Mayewski, director of UMaine’s Climate Change Institute, and 11 colleagues from China, Australia and Maine describe evidence from ice cores pointing to an […]

Locked in ice cores are clues to how climate evolved over thousands of years. But just what do scientists look for in the frozen timeline?   To access the complete UMaine Today Magazine article, please visit the following website: UMaine Today website

Brenda Hall is a leading young scientist studying evidence of abrupt climate change that occurred in Antarctica thousands of years ago. Working on ice sheets at the bottom of the world, Hall and her team use tweezers and spoons to hunt for those clues — bits of algae, shell or animal skin — that are […]

As the Ice Age ended almost 14,000 years ago, glaciers moved through Down East Maine, leaving scars on the landscape that are still visible to the trained eye. Now a UMaine geologist wants to share with the public the scientifically and historically significant evidence of the deglaciation trail.     To access the complete UMaine Today […]

Humans are the only animals that enter conflicts seeking an eye for an eye. Indeed, lethal revenge is not a useful evolutionary adaptation, argues University of Maine anthropologist Paul Roscoe. While revenge as a motive for war can be found throughout history, in today’s thermonuclear age the result can be annihilation.   To access the […]

On the desert coast of Peru, archaeologist Dan Sandweiss made a discovery that revolutionized the study of El Niño and its effects on civilization. What he found in the ancient clamshells has led to greater understanding of climate and culture.
