balancing stress resistance SKN-1 gene
Instead of completely deactivating a gene in an all-or-nothing approach, partially curbing its responses could strike a healthier balance between fighting infection and maintaining metabolism. (Photo/Aleksandr Simonov, Shutterstock)

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.
