We look forward to your continuing to be a friend for many, many years. Miami Book Fair International and Miami Dade College work handinhand to bring this book fair to us every year. Its a wonderful, this wonderful cultural affair that thousands and thousands of fairgoers are enriched by each and every year so thank you all. Come on and have a seat, please. And as you know, our sessions are being streamed live by cspan.

âSee-Through Soil Could Help Farmers Deal With Future Droughts
In research that may eventually help crops survive drought, scientists at Princeton University have uncovered a key reason that mixing material called hydrogels with soil has sometimes proven disappointing for farmers.
Hydrogel beads, tiny plastic blobs that can absorb a thousand times their weight in water, seem ideally suited to serve as tiny underground reservoirs of water. In theory, as the soil dries, hydrogels release water to hydrate plants’ roots, thus alleviating droughts, conserving water and boosting crop yields.
Yet mixing hydrogels into farmers’ fields has had spotty results. Scientists have struggled to explain these uneven performances in large part because soil being opaque has thwarted attempts at observing, analyzing and ultimately improving hydrogel behaviors.
