Nutrition or pathogen? Balancing healthy metabolism and stress resistance

A study led by the USC Leonard Davis School of Gerontology indicates that the negative long-term effects of fighting off infections could be mitigated by tweaking how a specific gene directs cells to respond to stressors.

Antibiotic-resistant genes are well removed by purification used to recycle wastewater but final quality is influenced by environmental factors

A team led by USC Viterbi’s Adam Smith has found that purified water returned to Southern California aquifers for storage and reuse blends with antibiotic-resistant bacteria already found in the aquifer.
