This month marks the 30th anniversary of the Chernobyl nuclear disaster. On April 26, 1986, technicians conducting a test inadvertently caused reactor number four to explode. Several hundred staff and firefighters then tackled a blaze that burned for 10 days and sent a plume of radiation around the world in the worst-ever civil nuclear disaster. More than 50 reactor and emergency workers were killed at the time. Authorities evacuated 120,000 people from the area, including 43,000 from the city of Pripyat. Reuters reports that a huge recently-completed enclosure called the New Safe Confinement—the world's largest land-based moving structure—will be “pulled slowly over the site later this year to create a steel-clad casement to block radiation and allow the remains of the reactor to be dismantled safely.” Gathered below are recent images of the ongoing cleanup work and the ghost towns being reclaimed by nature within the 1,000-square-mile (2,600-square-kilometers) exclusion zone in Ukraine.

If the Supreme Court were a stock market, the last few years have been as a bull market in conservative constitutional theories. With a tenuous but real 5-4 conservative majority in place, advocacy groups raced to get their pet theories before the Court. In some cases—campaign finance and gun rights, for example—the race paid off, producing 5-4 wins for radical shifts of doctrine. In others (think about public-employee unions) it has not.

Bull markets tempt investors into unwise wagers. History, I suspect, will so regard the appellants in Evenwel v. Abbot, the “one-person-one-vote” (OPOV) case decided Monday. In Evenwel, the Court unanimously rejected an advocacy group’s invitation to throw American politics into turmoil, and in the process to shift power from immigrants to natives, from non-whites to whites, from young people to the aging, and, by coincidence, from the Democratic to the Republican Party.

Disclosures from the Panama Papers are rocking the global political elite, with calls for the resignation of Iceland’s prime minister and protestations of innocence from the children of Pakistan’s leaders.

The documents were published Sunday by the International Consortium of Investigative Journalists, Süddeutsche Zeitung, the German newspaper, and several news organizations around the world, including the BBC, after a yearlong investigation. The actions described in the documents are not necessarily illegal, but some of the documents reveal a clandestine web of shell companies, their real owners concealed under layers of secrecy, and connections to firms in different tax havens.

News organizations from around the world have published investigations based on a massive trove of leaked documents they say reveal corruption and questionable business dealings of world leaders, politicians, sports stars, and others.

The German newspaper Süddeutsche Zeitung said Sunday it received encrypted internal documents from Mossack Fonseca, a Panama-based company that sells offshore shell companies around the world, from an anonymous source more than a year ago. The leak amounts to approximately 11.5 million documents—or 2.6 terabytes’ worth of data—on 214,000 shell companies spanning a period between the 1970s and 2016.

The documents, which have been dubbed the “Panama Papers,” contain mostly emails, PDF files, and photo files belonging to Mossack Fonseca, one of the largest providers of offshore financial services. They may represent the world’s biggest-ever leak of classified information.

The release of Batman v Superman: Dawn of Justice, which was greeted with negative reviews, a huge opening weekend at the box office, and then a precipitous drop, has inspired a new wave of hand-wringing about the state of superhero movies. With that in mind, a refreshing cultural nugget surfaced online Monday: a conversation between two of the most influential comic-book directors, Richard Donner and Christopher Nolan, on the appeals and challenges of the genre. The easiest thing to take away from it? Hollywood’s superhero trend, like so many fads the industry previously embraced, is headed in the wrong direction.

Nolan, of course, directed three Batman films that helped revive critical interest in the comic-book hero (along with Bryan Singer’s X-Men and Sam Raimi’s Spider-Man). But Nolan says his Batman Begins (2005), The Dark Knight (2008), and The Dark Knight Rises (2012) were deeply indebted to Donner’s 1978 film Superman, a landmark work in the superhero genre. Their 25-minute conversation is an extra on the DVD box-set for Nolan’s Batman trilogy and is hosted online at Dailymotion. Most importantly, the two discuss the difficulty and rewards of shooting “practically” (with special effects largely done in-camera without CGI assistance), a method that’s been quickly abandoned in the new superhero economy, to the detriment of fans.

Jürgen Mossack was already a citizen of the world when he first hung his shingle in Panama City in 1977. Born in Germany and raised and educated in Panama, the twenty-something had gone to London to work as a lawyer in 1975, but he returned two years later and began practicing. Since then, the firm he founded has become a global behemoth—hundreds of employees spread around the world, with special expertise in creating tax shelters for wealthy global elites. The firm is also, according to documents in the “Panama Papers,” deeply involved with all manner of unsavory and possibly illegal practices across continents; though Mossack Fonseca itself has strenuously denied any allegations of wrongdoing.
