Editor's note

A nationwide prisoner’s strike is now in its second week, with an unknown number of inmates refusing to eat or work to protest dilapidated facilities, harsh sentences and other issues. They’re also demanding more than the pennies per hour they are typically paid to do a wide variety of work, from fighting wildfires in California to packaging Starbucks coffee. Ethics aside, the practice may run afoul of a number of U.S. legal commitments, including the 13th Amendment to the Constitution, writes Ruben J. Garcia, a law professor at the University of Nevada, Las Vegas.

At a White House dinner for evangelical leaders on Monday night, President Trump promised to protect religious liberty. And earlier last month, Attorney General Jeff Sessions announced the creation of a religious liberty task force. Historian of religion David Mislin explains how far evangelical views have shifted. Back in the 19th century, he writes, some evangelical Christians argued that a religion that needed protection from government had no reason to exist at all.

And how do your cells keep DNA from getting tied up in knots? It’s a bit of a biological mystery – one that mathematicians are helping to unravel. Mariel Vazquez at the University of California, Davis describes her research on the many shapes of DNA.
