A company that does DNA testing for the police etc just bought one of this genealogy sites
A DNA Firm That Caters to Police Just Bought a Genealogy Site
In 2018, GEDmatch played a key role in reopening the 40-year-old Golden State Killer case. Now a company that serves law enforcement is gobbling it up.

Taking Sex Differences in Personality Seriously

@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 well yea of course and yes that was how he was caught...some of the tech was created by a kiwi Chick in the US.

I didn’t know about the kiwi chick, that’s pretty cool

More about DNA tests ,
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.

Probably can go in here...
Chinese paddlefish, one of world's largest fish, declared extinct
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.

@taniwharugby haha yea, timescales like that are too hard for my brain to comprehend
Like that ones about one type of dinosaur being closer in time to us than another type of dinosaur.

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.
