A DNA test restored my lost African ancestry. Or so I thought

UC Irvine linguist uses language and DNA to trace Latin America’s African roots

Though he wasn’t the first researcher to contact the Palenquero people, he was the first to spend periods up to several months living in the area and becoming fluent in their language. He returned several times and spent summers living in the 4,000-person village, including with his wife and young daughter.

Alexandria Ocasio-Cortez Tells Lindsey Graham to Visit African-American History Museum After DNA Preferences Joke

Congresswoman-elect Alexandria Ocasio-Cortez continued a spat with Republican Senator Lindsey Graham this week by telling him to visit the Smithsonian Institution’s National Museum of African American History and Culture to get educated about DNA preferences.

The Twitter dispute began on Sunday after reports emerged that American officials used tear gas in an attempt to stop hundreds of migrants in a caravan from Central America from crossing the border between the United States and Mexico near Tijuana.

“Asking to be considered a refugee & applying for status isn’t a crime,” Ocasio-Cortez tweeted. “It wasn’t for Jewish families fleeing Germany. It wasn’t for targeted families fleeing Rwanda. It wasn’t for communities fleeing war-torn Syria. And it isn’t for those fleeing…

DNA shows Baby June of African and central Asian ancestry

Death of Baby June now under investigation as a homicide. (WPEC)

The Palm Beach County Sheriff’s Office says it’s now investigating Baby June’s death as a homicide.

An off-duty Boynton Beach firefighter found the infant’s body floating in the Boynton Beach inlet six months ago. The baby had no bruises or marks on it, only a prick on her heel indicating she was born in a hospital.

Detectives say the body likely floating up the coast from Broward County based on the tide and condition of Baby June’s body, however the department says it could have traveled from even further South.

Monday, investigators said they used Parabon NanoLab services to obtain the infant’s DNA.

The results show Baby June is an even mix of African and Central Asian ancestry….

DNA data from Africans reveals sequences that we’d missed

Enlarge / The first printout of the human genome to be presented as a series of books, displayed in the ‘Medicine Now’ room at the Wellcome Collection, London.

The human genome sequence, first published in 2001, has some important information missing. The latest version of it, called GRCh38, has a monstrous 3.1 gigabases of information—but that’s still not enough. A letter published in Nature Genetics this week finds that the reference genome is missing a colossal 10 percent of the genetic information found in the genomes of hundreds of people with African ancestry—information that also appears in other human populations.

The “human genome” is in fact assembled from the genomes of just a handful of people, with the majority of GRCh38 coming from just…
