Ice-Free Radiative Convection Drives Spring Mixing in a Large Lake
July 10, 2019
When freshwater lakes fall below the temperature of maximum density, solar-driven radiative convection can become a major source of turbulent mixing. As the sun heats near-surface waters, the denser (warmer) waters sink rapidly throughout the water column, driving increased mixing and vertical transport. The current paper, co-authored by Dr. Cary Troy, Associate Professor in Purdue's Lyles School of Civil Engineering and C4E Affiliate, highlights the importance of this mixing mechanism as observed during a 2-week experiment at a 55m deep site in a large, ice-free lake (Lake Michigan, USA).

Study highlights nitrogen efficiency gains in corn hybrids over 70 years
July 8, 2019
During the past 70 years, hybrid corn varieties have increased both yield and nitrogen use efficiency at nearly the same pace, largely by preserving leaf function during grain filling. The Purdue University study’s findings offer strategies for corn breeders who want to continue to improve yields and nutrient efficiencies.

How to feed the world and preserve the environment
May 21, 2019
Farmers bear much of the burden for growing the food to feed billions of people as the world's population continually trends upward. On one hand, feed the world. On the other, preserve the environment. Sylvie Brouder, a professor in the Purdue Department of Agronomy, knows it's possible to do both.

Mazda Foundation grants for environmental conservation programs now open
May 15, 2019
Through the Mazda Foundation, Mazda and its employees work together to proactively help their neighbors to build a better, brighter future. With contributions exceeding $12.5 million since its founding in 1992, the Mazda Foundation is playing a meaningful role in helping thousands of Americans realize their aspirations and dreams. It's also important to note that programs the Mazda Foundation supports range from children's organizations and educational scholarships to food banks, environmental programs and crucial disaster relief efforts.

Organohalogen Flame Retardants Used in Consumer Products Cannot Be Assessed for Hazards as a Single Class, But Can Be Assessed in Subclasses, Says New Report
May 15, 2019
Since the 1970s, flame retardants have been added to materials to meet flammability standards. However, some flame retardants have migrated out of products, causing environmental contamination and damage to human health. A new report from the National Academies of Sciences, Engineering, and Medicine offers guidance to the U.S. Consumer Product Safety Commission on how to conduct a hazard assessment of flame retardants. Dr. Jennifer Freeman, Associate Professor in the School of Health Sciences and convener for C4E's Chemical Exposures signature research area, served on the Committee to Develop a Scoping Plan to Assess the Hazards of Organohalogen Flame Retardants.

Who owns and farms land can create barriers to conservation
April 23, 2019
WEST LAFAYETTE, Ind. — As stewards of vast swaths of land, farmers are important allies in U.S. conservation efforts, but there is evidence to suggest those farming on rented land adopt conservation practices at a lower rate.

U.S. forests’ changes are double-edged sword for environment
April 18, 2019
WEST LAFAYETTE, Ind. – Climate change, nitrogen deposition and fire suppression are leading to shifts in the types of trees that dominate American forests. These changes will have environmental consequences, potentially positive and negative, according to a Purdue University study.
