Upon reviewing their initial findings, a few things stood out.
Soybean oil mixed better with the polymers used to create their rubber compounds, making it a very flexible option, Woloszynek said.
It also has a low glass transition temperature, meaning it freezes at very low conditions. If you think of a high-performance summer tire, it s not really suitable for winter conditions because the rubber compound is formulated so that it grips the road in dry conditions and warm conditions, he said. When it gets cold, that compound has a higher glass transition temperature, so then, as the temperature of the air gets cold, that rubber starts to get stiffer.

Billy Gibbons intends to die on this land.
At 70, the bespectacled Black farmer may very well be the last heir to work the family plot; 80 acres of black soil in Browntown, Alabama, an unincorporated community less than 20 miles north of Prattville.
Gibbons’ parents pinched and scraped to purchase the acreage for $850 in 1940. They intended to pass it down to him and his brother; but he died in 1976 after contracting meningitis while away at military training in Fort Polk, Louisiana.
“I can remember all of this was woods,” Gibbons said, waving his arm over the crop land that extended before him. It was a brooding morning that had already spilled rain and left his feet besieged by shallow pools of muddy water.
