Heat waves kill hundreds of people each year in the U.S., most of them over 70 years of age. The vast majority die of heart attack or heart failure, largely because of the demands put on the heart as it tries to pump large amounts of blood to the skin to dissipate heat. Penn State researchers have pinpointed several ways the blood vessels in our skin change as we age, making us more susceptible to heat-related heart problems.
Lori Hepner's work on transforming Arctic landscape photographs will be supported by a grant from the Pittsburgh and Heinz Foundations.
Chasing storms and satellites with a plane — that’s what Penn State researcher Ken Davis and his NASA-funded research team will spend part of their summer doing. The team, which is scheduled to start its first research flight next week, will be taking a new approach to studying how weather transports greenhouse gases across different regions of the U.S.
Air pollutants interact with and break down plant-emitted scent molecules, which insect pollinators use to locate needed food, according to a team of researchers led by Penn State. The pollution-modified plant odors can confuse bees and, as a result, bees' foraging time increases and pollination efficiency decreases. This happens because the chemical interactions decrease both the scent molecules' life spans and the distances they travel.
Penn State scientists are helping crops survive drought and poor soils by redesigning their roots, from external architecture to internal anatomy.
Issues of flood, drought and a changing weather dynamic raise ethical and moral questions, including issues of justice and fairness between different populations, and between people and nature. To address such issues, constructive dialogue and community based discussions provide a way to find solutions and address the moral and ethical dilemmas raised.
Susan Spear, director of the U.S. Forest Service's Wilderness and Wild & Scenic Rivers programs in Washington, D.C., recently spoke to Penn State students and faculty members about the 110-year-old agency’s history and future.
At the Paris Climate talks, global society agreed to pursue a rapid decarbonization of the global economy to cap total global warming at 1.5 degrees Celsius. Such actions would prevent some dire effects of human-caused climate change. What are some of the ethical issues from global climate change?
Climate change is a global issue and affects all of us. You most likely have read about or discussed climate concerns, but an often overlooked topic is gender and climate change. In today’s Ask an Ethicist column, our ethicist brings to light this often overlooked topic and explains why gender should be part of the climate change conversation.
Richard Alley, Evan Pugh Professor of Geosciences, will present the fourth quadrennial Frank Whitmore Lecture on Chemistry Education and Public Policy at 7:30 p.m. April 19 in 100 Thomas Building. Titled “Climate and Energy: Big Challenges and Bigger Opportunities,” Alley’s special Earth Week lecture is free and open to the public.
An ice sheet model that includes previously underappreciated processes indicates that sea level may rise almost 50 feet by 2500 due to Antarctic ice sheet melting if greenhouse gas emissions continue unabated, according to researchers from Penn State and University of Massachusetts, Amherst.
The massive global livestock industry holds the key to mitigating greenhouse gases from the agriculture, forestry and land-use sector, but actual reductions in the foreseeable future likely will be just a fraction of what technically is possible.
That's the conclusion of a study conducted by an international team of researchers that included Alex Hristov, professor of dairy nutrition in Penn State's College of Agricultural Sciences
Extreme weather events like floods, heat waves and droughts can devastate communities and populations worldwide. Recent scientific advances have enabled researchers to confidently say that the increased intensity and frequency of some, but not all, of these extreme weather events is influenced by human-induced climate change, according to an international National Academies of Science, Engineering, and Medicine report released today (March 11).
While a majority of middle and high school science teachers teach climate change in their classrooms, most aren’t devoting the recommended amount of time to the topic—and when they do, their students may be getting mixed messages. Those are the findings of a survey of middle and high school science teachers conducted by Eric Plutzer, Penn State professor of political science, and colleagues at Wright State University and the National Center for Science Education. Results of the survey are highlighted in an article published in the February 12 edition of Science.
As the planet warms and sea levels rise, storm surges are becoming more destructive. How will coastal towns adapt? The first step is accepting that disasters really can happen here.
