    @jegga the thing is, a relative of a criminal could submit their DNA and happily have them test it without knowing their cousin/subling/parent is a serial killer and inadvertently point the authorities in the right direction...

    I think serial killers usually keep their hobby on the downlow anyway , a relatives dna sample is how they caught the Golden state killer apparently .
    I think we talked about that rape and murder suspect in NZ who's sister the police monitored until they caught her drink driving and used her dna sample to catch her brother?

    @jegga think it was discussed in the Bear Brook podcast, while trying to identify some victims of an unrelated crime the tech found the Golden State killer.

    More about DNA tests ,

    Jack Herrera  /  Dec 27, 2019  /  Biology

    DNA tests can’t tell you your race

    DNA tests can’t tell you your race

    None of the DNA-test companies explicitly offer to tell consumers their racial make-up. There’s one simple reason for that: The science just doesn’t exist.

    Interesting series of tweets from Neil de Grasse Tyson

    And about 8 subsequent tweets.

    Could go, and in fact may already have gone*, supernova.

    Native to China’s Yangtze River, these fish grew 23 feet in length, but haven’t been spotted since 2003.

    I always struggle to comprehend this, makes my head hurt 🤯

    We analysed the amounts of lead and uranium isotopes in these crystals using mass spectrometry, and found their clocks had been reset 2.229 billion years ago (give or take five million years). That’s when we realised Yarrabubba coincided with a major change in Earth’s climate.

    Yeah dinosaurs existed from 240m years ago to 60m years ago.

    So front end dinos existed 180m before the last ones, only 60m years ago.

    Only a tiny fraction of the 4.5 billion years earth has existed, or 3.5b years of life.

    On a similar note the mammoths and pyramids one gets me.

    one i read the other day was that the founding of Cambridge University predates the Aztec empire. Which, while not of the same mind-bending time scale, still surprised me
