The standard text, Baselt, records deaths with concentrations at 1 mg/l, the concentration found in Kelly".
The flies' internal alcohol concentrations at each stage are very similar to those of human drinkers, she said.
Technology allows us to determine concentrations at parts per trillion.
The levels found "greatly exceed concentrations at which severe toxic effects are known to occur," the scientists found.
On the one hand, he's loaned that voice to an ambitious project: stabilising atmospheric carbon concentrations at 350 parts per million.
The most ambitious policy proposals to date out of the US and Europe aim to stabilise carbon concentrations at 450 ppm by 2050.
The framework pledges to stabilize greenhouse-gas concentrations "at a level that would prevent dangerous anthropogenic interference with the climate system".
