  • Energy Saving Smart Windows

    Energy Saving Smart Windows
    Oct 1 2025
    How do you keep a building comfortable without wasting energy? A Penn State team is tackling that question with an innovative smart window. Using a responsive polymer, the window can block visible light, infrared heat, or both—automatically, without sensors or electricity. The technology could dramatically reduce energy use in buildings while giving architects new freedom to design spaces that work with, rather than against, the sun.

  • Indigenous communities and Amazon oil

    Indigenous communities and Amazon oil
    Aug 1 2025
    The Amazon, home to rich biodiversity and vital carbon-storing ecosystems, is also the ancestral land of Indigenous communities who are grappling with the devastating effects of oil extraction across Ecuador, Peru, and Colombia. These communities live amid widespread pollution from oil spills, toxic chemicals, and industrial infrastructure, which threaten their way of life and the health of their environment. In response, they are working alongside researchers to map the environmental destruction and strengthen their efforts to hold oil companies accountable while fighting to protect their lands and preserve their cultural heritage.

  • Climate change, extreme heat, and infant health

    Climate change, extreme heat, and infant health
    Jul 1 2025
    Heat significantly affects pregnant women and infants, increasing risks like dehydration, heat exhaustion, and developmental issues in children. Expectant mothers are more vulnerable due to physiological changes, while infants face heightened danger because of immature temperature regulation. These challenges are further intensified for families with limited resources. Researchers are investigating these impacts to provide lawmakers with the knowledge needed to create protective measures for these at-risk groups.

  • Cooling high-performance buildings

    Cooling high-performance buildings
    Jun 1 2025
    Cooling is energy-intensive, with air conditioning consuming a significant portion of electricity in homes and commercial buildings, while also contributing to greenhouse gas emissions and climate change. This creates a cycle of increasing energy demand for cooling. However, innovative materials that cool when strained offer a promising, sustainable solution for various applications.

  • Measuring nitrous oxide emissions

    Measuring nitrous oxide emissions
    Apr 1 2025
    Nitrous oxide is a potent greenhouse gas with nearly 300 times the warming potential of carbon dioxide, making even small emissions highly impactful. Agriculture, particularly soil management, is the largest source of nitrous oxide. To better understand and manage these emissions, researchers have developed a system for continuous monitoring on farms and other land management purposes.

  • Low-carbon cement from farm waste

    Low-carbon cement from farm waste
    Jan 1 2025
    Cement, a major component of concrete, is a significant contributor to global carbon emissions. Researchers are exploring agricultural waste as a potential alternative to cement, aiming to reduce carbon footprint while also finding new uses for farm byproducts. However, the feasibility and effectiveness of this solution depend on the collaboration between researchers and farming communities.
