President Donald Trump calls her a fake “Pocahontas.” But genetic analysis finds that US Senator Elizabeth Warren does have Native American DNA, the Boston Globe reports.
What happened: Warren, a Democrat from Massachusetts, sent her DNA anonymously to the Stanford University laboratory of Carlos Bustamente, a well-known specialist in genetic ancestry. (You can read a new Q&A with Bustamente here, published today in MIT Technology Review.)
The test: Warren’s ancestry was analyzed on a “chip” that looked at 764,958 sites where people’s DNA letters commonly differ. This is the same technology used in commercial direct-to-consumer ancestry tests, like that from Ancestry.com.
What they found: According to a summary of the lab’s findings, Warren’s genome is more than 95% European. But she does have five segments in her DNA that look Native American. The largest spans about 4,700,000 DNA letters. While that is less than 1/1,000th of her DNA, it was enough for Bustamante to conclude with confidence she probably has a Native American ancestor about six to 10 generations ago, according to an executive summary of the findings.
Now what: On July 5, during a political rally in Montana, Trump dared Warren to submit to a DNA test and offered a bet, according to the Washington Post: “I will give you a million dollars, paid for by Trump, to your favorite charity, if you take the test and it shows you’re an Indian.”
Saudi Arabia plans to spend $1 billion a year discovering treatments to slow aging
The oil kingdom fears that its population is aging at an accelerated rate and hopes to test drugs to reverse the problem. First up might be the diabetes drug metformin.
Anti-aging drugs are being tested as a way to treat covid
Drugs that rejuvenate our immune systems and make us biologically younger could help protect us from the disease’s worst effects.
Why China is still obsessed with disinfecting everything
Most public health bodies dealing with covid have long since moved on from the idea of surface transmission. China’s didn’t—and that helps it control the narrative about the disease’s origins and danger.
A new storage technique could vastly expand the number of livers available for transplant
It allows donor livers to be held for days—significantly longer than the standard now–and even treated if they are damaged.
