  • Why are other researchers skeptical?

    For starters, there are questions about whether K2-18 b even has water — or a surface that could support life. Modelling studies of it and similar planets suggest that they are probably barren4,5. “A lifeless mini-Neptune scenario remains the most parsimonious explanation,” says Joshua Krissansen-Totton, a planetary scientist at the University of Washington in Seattle.

    Then there’s the issue of whether DMS or DMDS is actually present, or whether the signal is spurious. The measurement reported by the Cambridge team is “really pushing the limit of what JWST can do”, says Laura Kreidberg, an astronomer at the Max Planck Institute for Astronomy in Heidelberg, Germany.

    Schmidt and his colleagues recently re-analysed the 2023 claim from the Cambridge team and found no evidence of biosignature molecules in the data6. Schmidt says that the new observations are “pretty noisy, and any reported features could still just be statistical fluctuations”. The Cambridge researchers, however, say that there is just a 0.3% probability that the signal is due to chance.





























  • Know that you are not just sharing your own genetic information, but also that of your blood relatives within 2 generations.

    Anyone from your grandparents and their offspring can be matched to the DNA you send in. Surpise, your father has an illegitimate child and the will is now in dispute. Oh, looks like DNA of one of your relatives turned up in a criminal investigation so now most are being investigated. That’ll be a fun discussion at the next get together…

    There is far more information packed in your genes than most laypeople understand. IMO this whole industry should have been legislated to either force destruction of all data once the report is generated or the consent of all your family members be a prerequisite.
