U.S. Farm & Biofuel Leaders to White House: Pull EPA Back From the Brink

America’s top biofuel and farm advocates called on the White House to take immediate action to address reports that the Environmental Protection Agency (EPA) may soon seek to destroy demand for billions of gallons of low-carbon biofuels under the Renewable Fuel Standard (RFS). The following joint statement was issued by the American Farm Bureau Federation,  Advanced Biofuels Business Council, American Soybean Association, Growth Energy, National Biodiesel Board, National Corn Growers Association, National Farmers Union, and Renewable Fuels Association:

“While a formal proposal has not been released, the expected standards would destroy a decade of progress on low-carbon biofuels and brazenly violate the promises that President Biden made to farmers, green voters, and his own allies in Congress.

Video: Porcine Gut Models in Nutrition Research - Dr. Li-Hsuan Chen



In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Li-Hsuan Chen, postdoc researcher at Aarhus University, discusses how porcine intestinal cell lines and organoids can help study the impact of nutrition on gut health. He explains how in vivo piglet trials identify diet-driven shifts in microbiota and metabolites, while in vitro models allow researchers to test specific metabolites, barrier function, immune markers, and future organ-on-chip systems before moving back to animal studies. Listen now on all major platforms!

"In vitro models can reduce early animal use by helping researchers screen nutritional candidates before moving back to in vivo trials."

Meet the guest: Dr. Li-Hsuan Chen / li-hsuan-chen-9a95a7279 is a postdoc researcher at Aarhus University in Denmark. Research focuses on porcine gut health, host-microbe interactions, cell lines, and organoids, with PhD work at Aarhus University studying how dietary protein and amino acid levels shape gut microbiota, microbial metabolites, and intestinal epithelial responses.
