Explore the eye-opening science of LASIK: corrective laser eye surgery that focuses on reshaping the cornea to fix blurry vision.

Uploaded 19-11-19

--

In 1948, Spanish ophthalmologist Jose Ignacio Barraquer Moner was fed up with glasses. He wanted a solution for blurry vision that fixed the eye itself, without relying on external aids. The surgery he eventually devised was called “keratomileusis,” and his technique focused on reshaping the cornea— what we now know as LASIK. So how does laser eye surgery actually work? Dan Reinstein explains.

Uploaded 26-03-19

Whatever corner of the globe you find humans in today, you’re likely to find another species as well: dogs. So how did one of our oldest rivals, the wolf, evolve into man’s best friend? David Ian Howe traces the history of humanity’s first domesticated animal.

Get to know the story of Radio Venceremos, an underground radio collective that fought US-backed fascism during the Salvadoran Civil War.

--

Since the 1800s, a handful of oligarchs had controlled nearly all of El Salvador’s land, forcing laborers to work for almost nothing. But in 1980, farmers and urban workers formed guerrilla groups to overthrow the US-backed dictatorship. These revolutionaries were attacked from every direction, but a group of rebels refused to be silenced. Diana Sierra Becerra shares the story of Radio Venceremos.

Dig into sortition, a system where officials are selected via lottery, and how it could address the problems of modern democracies.

--

Elections are tools that ensure a nation’s citizens all have an equal political voice. But these so-called “great equalizers” are often plagued by corruption, partisan divides, and uninformed voters. Which is why some of democracy’s first and most famous practitioners used a different approach: sortition. Michael Vazquez explores how this system could address modern democracy's biggest problems.
