Engineered bacteria not exposed to inflammatory signals do not turn on the memory circuit and thus remain colorless. In the presence of the inflammatory chemical tetrathionate, the memory circuit switches on and colors the engineered bacteria blue.

This schematic diagram shows the overall conceptualization of how metabolically engineered E. coli produced TPA from pX. The engineered E. coli was developed through reconstituting a synthetic metabolic pathway for pX conversion to TPA and optimized for increased TPA yield and byproduct elimination. Two-phase partitioning fermentation system was developed for demonstrating the feasibility of large-scale

In the periplasm — the space between the inner and outer membranes of a bacteria’s cell wall — defensive proteins that detect a poison assemble like barrel staves to form a tunnel between pumps in the cell’s inner and outer membranes to eject the intruders.

Alligators may be coming for you, according to a Kansas State University researcher. While the

Pumas are not the loners they were once thought to be. Credit: © outdoorsman / Fotolia Pumas, long known as solitary carnivores, are more social than previously thought, according to a new Panthera study published in the peer-reviewed journal Science Advances. The findings provide the first evidence of complex social strategies in any solitary carnivore

Horse making demands: The horse a) lightly pushes and b) looks at the caretaker standing outside the paddock. Food is hidden inside one of the two silver buckets behind them. When horses cannot obtain this food by themselves, they give humans visual and tactile signals. Credit: Image courtesy of Kobe University A new study has

Horses are grazing annual warm-season forages in St. Paul, Minnesota. Credit: Michelle DeBoer When you picture a horse, you may imagine it grazing contentedly in a grassy pasture. Grazing lets horses move around naturally outdoors and socialize with other horses. And grass is an easily available, nutritious feed that horses like eating. If you have
