Scientists put the stopwatch on cannabis intoxication

A comprehensive analysis of 80 scientific studies found a 'window of impairment' of 3-10 hours caused by moderate to high doses of THC. Impairment duration varies depending on dose, method of consumption, and user's regularity., The study suggests that laws should focus on safety on the roads rather than arbitrary punishment.

Life on Venus? First we need to know more about molecules in the atmosphere

An international team of scientists has discovered the spectral signatures of almost 1000 atmospheric molecules that could be related to phosphine production. The study provides a novel approach to follow up potential biosignatures and will aid in the detection of life on exoplanets as more powerful telescopes come online.
