Genetic Data From Over 20,000 U.S. Children Misused for โ€˜Race Scienceโ€™

Incredibly important story that everyone should read.

These are not disorganized lone actors, but well-funded and powerful networks to be treated as serious threats.

They are using our work to push a eugenicist and racist agenda that is scientifically invalid and morally reprehensible.

Ancient DNA Reveals Twisted Roots of Syphilis Go Back 5,500 Years The first known outbreak of syphilis in Europe began at the turn of the 16th century, but on the distant continent of South America, the pathogen's history goes much deeper than that.

I learned about this dark side of syphilis when I took a history of medicine course. It is a remarkably resistant disease that brought armies to their knees and wrought tremendous societal damage.
