The memory of salt: searching for ancient microbial life biosignatures on Earth and Mars
Salt: both friend and foe. On Earth and Mars, some brines may preserve traces of ancient microbial life, others may destroy them. Using dead halophile cell envelope extracts, we show that UV and salt composition together control biosignature preservation. To get there, we had to tame salt in the lab
Debunking de novo NAD+ Synthesis in C. elegans: Artifacts Arising from Impure Quinolinic Acid
Axenic culture system reveals that C. elegans lacks the necessary mechanisms for de novo synthesis of NAD+. Commercially available quniolinic acid products contain nicotinic acid impurity, potentially producing misleading information.
