Undiscovered - Mouse’s Vineyard

Martha’s Vineyard has a Lyme disease problem. Now a scientist is coming to town with a possible fix: genetically engineered mice.

An island associated with summer rest and relaxation is gaining a reputation for something else: Lyme disease. Martha’s Vineyard has one of the highest rates of Lyme in the country. Now MIT geneticist Kevin Esvelt is coming to the island with a potential long-term fix. The catch: It involves releasing up to a few hundred thousand genetically modified mice onto the island. Are Vineyarders ready?

FOOTNOTES

    Read Kevin Esvelt’s original paper describing the gene drive mechanism in eLife. Less technical descriptions available here via Scientific American, and here via Esvelt’s Sculpting Evolution Group. Watch Kevin’s July 20, 2016 presentation on Martha’s Vineyard (Unfortunately there is no direct link. Search “7.20.16” to find the video, titled “Preventing Tick-Borne Disease.”) Listen to Kevin Esvelt talk about gene drive on Science Friday. Read about Oxitec’s proposed mosquito trial in Key West, and watch the public meeting excerpted in this episode. Learn more about Kevin’s lab, the Sculpting Evolution Group.

50 Things That Made the Modern Economy - Barbed Wire

In 1876 John Warne Gates described the new product he hoped to sell as “lighter than air, stronger than whiskey, cheaper than dust”. We simply call it barbed wire. The advertisements of the time touted it this fence as “The Greatest Discovery Of The Age”. That might seem hyperbolic, even making allowances for the fact that the advertisers didn’t know that Alexander Graham Bell was just about to be awarded a patent for the telephone. But – as Tim Harford explains – while modern minds naturally think of the telephone as transformative, barbed wire wreaked huge changes in America, and much more quickly.
