Man claims to be a minority business owner after DNA test shows he’s 4% African

An insurance agent claims he should qualify as a minority business owner, because a DNA test shows he’s 4 percent African — enough, he believes, to make him “a certified black man.”

Ralph Taylor knows on the outside he looks like an average white guy, but he is trying using the results from his AncestryByDNA test to bolster his business in Lynnwood, Washington.

“I’ve always known that I’m multiracial,” the 55-year-old declared to the Washington Post.

The 2010 test showed that he’s 90 percent European, 6 percent indigenous American and 4 percent sub-Saharan African.

“I’m a certified black man. I’m certified black in all 50 states,” he said. “But the federal government doesn’t recognize me.”

Taylor is now in the midst of a legal battle with Washington…

DNA sleuths bolster case against three key African ivory cartels

DNA tests on smuggled elephant tusks have identified three major ivory cartels in Africa and are helping investigators bolster the criminal cases against some of the most dangerous traffickers, researchers said Wednesday.

Around 40,000 African elephants are killed every year for their tusks, which are illegally traded as part of a multibillion dollar industry that extends from Africa to Asia and beyond.

Traffickers conceal their ivory in shipping containers — but inspectors peer inside just 1 percent of the 1 billion containers sent around the world each year.

Where physical inspections fall short, genetic testing has come to the rescue, said the report in the journal Science Advances.

Lead author Samuel Wasser, a professor of biology at the University of Washington, said…

DNA evidence and lots of detective work have revealed the networks behind illegal trade in African elephant ivory, centering on three smuggling cartels in Kenya, Uganda and Togo.

The case is laid out in a paper written by a team led by Samuel Wasser, head of the University of Washington’s Center for Conservation Biology, and published today in the open-access journal Science Advances.

Wasser said the findings could figure in a complex case centering on Feisal Mohamed Ali, a reputed ivory kingpin based in Mombasa, Kenya. Feisal was convicted on trafficking charges in 2016 but was set free last month on…

DNA fingerprinting has helped conservationists and law enforcement teams identify three major cartels that dominate the elephant ivory-smuggling market, researchers said Wednesday.

Samples taken from seized elephant tusks link multiple shipments to cartels operating out of Africa, the team reported. The information they have gathered is already being used to solidify cases against smuggling kingpins, a Homeland Security official said.

Performance of Multitarget Stool DNA Testing in African American Patients – Cooper – – Cancer


Multitarget stool DNA (mt‐sDNA) is an approved method for colon cancer screening that is especially relevant for patients who cannot undergo colonoscopy. Although the test performance has been evaluated in a large clinical trial, it was limited to a predominantly white population. Given differences in the epidemiology and biology of colon cancer in African American individuals, the authors sought to compare the performance of mt‐sDNA between racial groups.


The authors prospectively identified patients aged ≥40 years who were referred for colonoscopy at an academic medical center and 2 satellite facilities….
