As the investigation continues into the oil spill along the California coast, new details emerged about the pipeline operator's long history of wreaking environmental damage. Plains All American operates the pipeline that burst near Refugio State Beach on the Gaviota Coast and dumped more than 105,000 gallons of crude oil into the ocean. Plains All American has been responsible for 175 spill incidents nationwide since 2006, including 11 in California.

Last Sunday’s broad daylight shoot-out between rival biker gangs in Waco, Texas left nine dead and eighteen others hospitalized, and shocked the nation. However, the Waco shootout also served to graphically underscore how drastically different the police and media treatment of violent incidents is when those involved are white. This racial disparity was intensely explored on Twitter this week by commentators and critics on hashtag#WacoThugs.

Stone tools unearthed at a site in Kenya predate any identified human ancestors -- previously thought to be the first makers of stone tools -- by hundreds of thousands of years. These finds "will force us [to rethink] what makes us humans ... Increasing knowledge of our remote past is casting doubts on previous certainties and is showing that the process of becoming what we are now is far more gradual than what we previously thought."

It took only a few minutes for Mr. Obama’s account to attract racist, hate-filled posts and replies. They addressed him with racial slurs and called him a monkey. One had an image of the president with his neck in a noose. But they appeared to be a small number in what was an otherwise social-media-fueled show of love for Mr. Obama, who was drawing followers at a rapid pace — nearly 2.3 million by Thursday afternoon.

The fundamental problem with both the “not now, maybe later” and the “not on your life” rejections of electoral politics is their small mindedness, their view that political activity is a zero sum game where a Sanders candidacy inevitably diminishes some other truly valuable activities because there are only a limited number of potential activists out there.

This Memorial Day, let us remember the men and women soldiers who have suffered and died from war-caused conditions called variably soldier's heart in the Civil War, shell shock in the First World War, PTSD in the Vietnam War, and moral injury in the Iraq War...Let us not forget those who died from the nightmares of war - at their own hand.

New York has a real subway. Seems like anywhere I want to go is walking distance from a station. There are 421 of them, so it figures they're close to almost anywhere along its 656 miles of tracks in four boroughs. The great thing about the subway is the people. New York is so diverse - it feels like you're seeing people from everyplace on earth in just a few subway cars. I see people tired from work, having trouble keeping their eyes open, or sometimes just asleep.

Michael Yates presents an analysis of how the war was conducted, what its consequences have been for the Vietnamese, how the nature of the war generated ferocious opposition to it (not least by a brave core of U.S. soldiers), how the war's history has been whitewashed, and why it is important to both know what happened in Vietnam and why we should not forget it.
