After growing a pure culture of the previously unidentified bacterium,
Sherwood s colleague Ryan Baugh an assistant professor of medicine showed that hatching C. elegans eggs in a nutrient-free environment shut down their development completely.
If the organism has enough nutrients its development can pass through to the next toll booth. If it doesn t have enough it stays at the toll booth until it has built up the nutrients necessary to get it the rest of the way.
Development isn t a continuous nonstop process says Schindler who is lead author of the study.

Improvements for OECD nutrient balance modelcurrently the static nutrient balance approach of OECD is used to assess nutrient emissions from agriculture.
The static approach ignores the accumulation of nutrients in the environment and overlooks the dynamic nature of the nutrient cycles Kuosmanen says.

#Scientists Discover Nutrient Sensor That Senses Amino acid Arginine Through a variety of mechanistic interactions mtorc1 interprets cues in the cellular environment including the availability of nutrients
How exactly does mtorc1 actually detect the presence of nutrients? Now it seems scientists in Sabatini's lab have at least a partial answer describing for the first time a protein that appears to sense the amino acid arginine.
