Well-written article that should however have presented a broader range of perspectives to highlight the controversy surrounding the de-extinction claim.

While the article includes regular references and effectively explains some of the scientific concepts underlying the research, it could benefit from including more scientific studies as references. The title (and the overall tone of the article) should be more balanced. The claim of “the return of the dire wolf” is an overstatement that fails to address the controversy surrounding the work. Indeed, while the article cites individuals outside the research team behind the work, it lacks the opinion of scientists who dispute the “de-extinction” claim: these scientists argue that the animals are not in fact the extinct species but rather a genetically modified version of the existing grey wolf. A more balanced perspective would have provided a more accurate explanation of the scientific and environmental implications of the research.

This article is a lay report of findings from a peer-reviewed research study, written by the scientists behind the original study. There is good referencing to scientific sources and previous studies throughout the article. Very good explanation of complex scientific concepts (e.g., epigenetic) and of the biology and compounds underlying cannabis-induced psychosis.

This article highlights findings from a peer-reviewed research article on the impact of a cannabis compound on sleep behaviour in animal models. The original article is mentioned in the text but a link to it is missing; and while there are quotes from the authors of the study, it lacks opinions from researchers not directly involved within the work and references are completely missing from the article. The article uses scientific jargon (such as REM, EEG) that could be simplified. The title doesn't provide any information on the actual article. The article however highlights several times that the research has been done in rodents and not in humans and that caution and further research are needed in order to draw any conclusions in humans.
