White supremacists believe in genetic ‘purity’. Science shows no such thing exists

Far-right white supremacist ideology is on the rise in Europe, North America and Australia. It appeals to a racist notion whereby many white supremacists see themselves as members of a “pure” race that is at risk of dilution and contamination.

Science does not support the idea of pure races with ancient origins. In the past few years, genetic sequencing of ancient and modern humans and related species has given us a flood of new information about how human populations have evolved.

The evidence reveals a history of ongoing genetic mingling, due to interbreeding between different populations and even species. Humans from different groups had children together, and even with Neanderthals and members of other now-extinct hominin species.

This mingling occurred constantly in the long process of human migration across the globe. Europeans inhabit one region of a large genetic continuum and are no more or less “pure” than any other

Some severe COVID-19 cases linked to genetic mutations or antibodies that attack the body — ScienceDaily

People infected by the novel coronavirus can have symptoms that range from mild to deadly. Now, two new analyses suggest that some life-threatening cases can be traced to weak spots in patients’ immune systems.

At least 3.5 percent of study patients with severe COVID-19, the disease caused by the novel coronavirus, have mutations in genes involved in antiviral defense. And at least 10 percent of patients with severe disease create “auto-antibodies” that attack the immune system, instead of fighting the virus. The results, reported in two papers in the journal Science on September 24, 2020, identify some root causes of life-threatening COVID-19, says study leader Jean-Laurent Casanova, a Howard Hughes Medical Institute Investigator at The Rockefeller University.

Seeing these harmful antibodies in so many patients — 101 out of 987 — was “a stunning observation,” he says. “These two papers provide the first explanation for why COVID-19 can be so

How genetic science helped expose a secret coronavirus outbreak in Iowa

POSTVILLE, Iowa — It wasn’t until their colleagues began to disappear that workers at Agri Star Meat and Poultry realized there was a killer in their midst.

First came the rumors that rabbis at the kosher plant had been quarantined. Then a man who worked in the poultry department fell ill. They heard whispers about friends of friends who had been stricken with scorching fevers and unbearable chills — characteristic symptoms of the novel coronavirus.

Where was the contagion coming from?

No one would say. Not Agri Star’s wealthy owner, who didn’t shut down production lines after cases were confirmed among workers. Not the Iowa Occupational Safety and Health Administration, which closed a complaint containing multiple allegations against the plant without an inspection. Not Iowa Republican Gov. Kim Reynolds, whose administration threatened to prosecute officials who released covid data and did not conduct testing at the plant until seven weeks
