The origin of flaked-stone tool production is older than 2.58 million years ago, according to an international team of scientists working at the Bokol Dora 1 archaeological site in the Afar region of Ethiopia. Previously the oldest evidence of flaked-stone tools was younger than 2.58 million years ago.
Members of the Penn State Science Policy Society recently visited Washington, D.C., where they met with officials from several congressional offices and nongovernmental organizations to discuss the promotion of science and evidence-based policy.
Michael Mann, distinguished professor of atmospheric science and director of the Earth System Science Center at Penn State, received the 2019 Praxis Award in Professional Ethics during a ceremony at Villanova University on April 11. A recognized expert on climate change, Mann received the award for his significant contributions to climate science and communication and advocacy efforts.
Two graduate students in the College of Earth and Mineral Sciences were recognized for their research and presentation skills during the 2019 Graduate Exhibition, hosted by the Graduate School at Penn State.
Catherine Hanagan, a senior studying geosciences at Penn State, conducted fieldwork around volcanoes in Iceland with funding from a Rodney A. Erickson Discovery Grant.
As decision makers balance economic, environmental and social aspects of living, planners and others need decision-making tools that support the process, but do not dictate the outcomes, so that trade-off choices can reflect a wide array of needs, according to a team of researchers who looked at an interactive program using trade-off diagrams.
Researchers found the recovery period following the second largest extinction on record, some 444 million years ago, had a bigger evolutionary impact than the extinction event itself on brachiopods, shelled, clam-like animals that once dominated the sea floor.
For the first time, the magnitude, time and duration of earthquakes in a laboratory setting were predicted by a team of researchers from Penn State and Los Alamos National Laboratory.
Pumping carbon dioxide into the ground to remove it from the atmosphere is one way to lower greenhouse gases, but keeping track of where that gas is, has been a difficult chore. Now, a team of researchers from Penn State and Lawrence Berkley National Laboratory are using previously ignored seismic waves to pinpoint and track the gas clouds.
The Greenland ice sheet melted a little more easily in the past than it does today because of geological changes, and most of Greenland's ice can be saved from melting if warming is controlled, says a team of Penn State researchers.
Chris Marone, a professor of geosciences in Penn State’s College of Earth and Mineral Sciences, has been selected to receive the European Geosciences Union’s 2019 Louis Néel Medal.
Undergraduate students traveled to the Pacific Northwest and studied volcanoes, earthquakes, tsunamis and more as part of a three-semester research course sponsored by the College of Earth and Mineral Sciences Center for Advanced Undergraduate Study and Experience (CAUSE).
A rapid rise in temperature on ancient Earth triggered a climate response that may have prolonged the warming for many thousands of years, according to scientists.
Microbes that thrive in some of the most extreme places on Earth have discovered another cozy place to live — inside homes across the United States.
Dozens of middle and high school students from across Pennsylvania recently spent a day at the Earth and Mineral Sciences Museum & Art Gallery at Penn State learning about women in geosciences.
