Is a Healthy 25-Year-Old Really at Risk for Macular Degeneration?

Paul Hoffman: So, Boonsri, tell me about the three tests that you took. I understand you came back and you started worrying about Crohn’s disease and mascular degeneration.

Boonsri Dickinson: Two of the companies, 23andMe and deCODEme, gave me some information that I could check, like, when I drink wine, my face gets flushed, I have dry earwax, I’ve brown eyes, I’m not a sprinter. And although it said that I’m likely tolerant to lactose, if I had a sip of milk, you guys would all want to hold your nose.

When I read my report on common diseases, I realized the information is useless. There’s no way to tell how accurate the so-called risks are until you actually have a disease.

Esther Dyson: Even then you don’t know what the risk was.

Boonsri Dickinson: Right. Crohn’s disease and macular degeneration are two diseases that I pay attention to, because I have poor eyesight. So loss of vision is something that meant something to me. And then Crohn’s disease is another one. I have a sensitive stomach. So I’ve learned what foods to avoid.

But the limitations, for me, were far greater. I’m half Asian and half European. So when I looked at the profiles, I got conflicting results just because they ask if you’re European or if you’re Asian. They haven’t worked out a way. Although one of the board members said that he was going to work on that.

Esther Dyson: Is that Patrick Chung?

Boonsri Dickinson: George.

Esther Dyson: Oh, he’s, sorry, scientific board.

Boonsri Dickinson: And so they haven’t found a way to calculate risk for people of mixed ethnicities. And since I wrote this story [“How Much Can You Learn From a Home DNA Test?”; from the September 2008 issue of “Discover” magazine] a year ago, the companies continue to update their Web sites with more diseases, more risks. But just because they’re adding more data doesn’t mean that they know more about the role that genes play in the onset of disease.

And only, Navigenics, the third company that I tested with, they offered in-house counseling. And even then their genetic counselor wouldn’t really tell me what my genetic profile meant. She just said I have to interpret it.

Genetic testing made Discover editor Boonsri Dickinson fear for the future of her eyes, and her gut.

Ideology drives us apart. Neuroscience can bring us back together.

A guide to making difficult conversations possible—and peaceful—in an increasingly polarized nation.

  • How can we reach out to people on the other side of the divide? Get to know the other person as a human being before you get to know them as a set of tribal political beliefs, says Sarah Ruger. Don't launch straight into the difficult topics—connect on a more basic level first.
  • To bond, use icebreakers backed by neuroscience and psychology: Share a meal, watch some comedy, see awe-inspiring art, go on a tough hike together—sharing tribulation helps break down some of the mental barriers we have between us. Then, get down to talking, putting your humanity before your ideology.

How to split the USA into two countries: Red and Blue

Progressive America would be half as big, but twice as populated as its conservative twin.

Strange Maps
  • America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
  • Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
  • Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America

Why a federal judge ordered White House to restore Jim Acosta's press badge

A federal judge ruled that the Trump administration likely violated the reporter's Fifth Amendment rights when it stripped his press credentials earlier this month.

WASHINGTON, DC - NOVEMBER 16: CNN chief White House correspondent Jim Acosta (R) returns to the White House with CNN Washington bureau chief Sam Feist after Federal judge Timothy J. Kelly ordered the White House to reinstate his press pass November 16, 2018 in Washington, DC. CNN has filed a lawsuit against the White House after Acosta's press pass was revoked after a dispute involving a news conference last week. (Photo by Alex Wong/Getty Images)
Politics & Current Affairs
  • Acosta will be allowed to return to the White House on Friday.
  • The judge described the ruling as narrow, and didn't rule one way or the other on violations of the First Amendment.
  • The case is still open, and the administration may choose to appeal the ruling.
