A new NASA EPSCoR grant will help South Dakota Mines researchers explore the next generation of lithium sulfur batteries. Those batteries could be powered by the waste produced from processing plants.

The research was a team effort that spanned disciplines at South Dakota Mines. A few of the experts who worked on this project joined In the Moment to explain their work and unexpected discovery.

Rajesh Shende, Ph.D., is a professor of chemical and biological engineering. He specializes in finding uses for agricultural byproducts.

And Edward Duke, Ph.D., is a professor of geology and geological engineering and the director of the South Dakota Space Grant Consortium and the South Dakota NASA EPSCoR Program.

Video: Dicamba Returns for Georgia Farmers: What the New EPA Ruling Means for Cotton Growers

After being unavailable in 2024 due to registration issues, dicamba products are returning for Georgia farmers this growing season — but under strict new conditions.

In this report from Tifton, Extension Weed Specialist Stanley Culpepper explains the updated EPA ruling, including new application limits, mandatory training requirements, and the need for a restricted use pesticide license. Among the key changes: a cap of two ½-pound applications per year and the required use of an approved volatility reduction agent with every application.

For Georgia cotton producers, the ruling is significant. According to Taylor Sills with the Georgia Cotton Commission, the vast majority of cotton planted in the state carries the dicamba-tolerant trait — meaning farmers had been paying for technology they couldn’t use.

While environmental groups have expressed concerns over spray drift, Georgia growers have reduced off-target pesticide movement by more than 91% over the past decade. Still, this two-year registration period will come with increased scrutiny, making stewardship and compliance more important than ever.
