Permawar: Islamic State fighters have over run the sprawling Yarmouk Palestinian refugee district in southern Damascus, Syria, bringing terror to the already embattled camp. The area has been the target of fighting and shelling for two years and yesterday reports emerged of killings and beheadings carried out by ISIS extremists.

After taking a battering in Tikrit, Iraq, it appears that the Islamic State is trying to expand in the other direction, taking advantage of the civil war chaos in Syria.

And ISIS continues to destroy irreplaceable antiquities in the territory it occupies while the world stands by, helpless. An opinion piece in the New York Times by Hugh Eakin of the New York Review of Books calls for the use of force. Eakin wrote that “Amid overwhelming evidence that the Islamic State’s barbaric campaign against culture amounts to a war crime, the world must be ready to use force to stop it.”

Nucular: The giant Hadron Collider, the world’s largest particle accelerator on the border of France and Switzerland, is back in operation after a two-year upgrade. In the scientific search for what’s known as “dark matter,” the collider is now capable of much higher speeds and more violent crashes to break down the universe’s tiniest parts.
