INDIA: Premier under attack

Angry opposition lawmakers shouted and crowded aisles in parliament Tuesday to demand that Prime Minister Manmohan Singh resign after an audit found the government lost huge sums of money by selling coal fields without competitive bidding. Bharatiya Janata Party lawmakers and other opposition leaders targeted Singh because he ran the coal ministry during the 2004 sale. The auditor's report exonerated Singh, but it estimated that private companies got a windfall profit of $34 billion because of the low prices they paid. The two houses were adjourned for the day after the opposition blocked proceedings.

POLAND: Probing Nazi death camp

When archaeologist Yoram Haimi decided to investigate his family's Holocaust history, he began to dig. After learning that two of his uncles were murdered in the Sobibor death camp in eastern Poland, he embarked on a landmark excavation that is shining new light on the workings of one of the most notorious Nazi killing machines, including pinpointing the gas chambers where hundreds of thousands were killed. "I feel like I am an investigator in a criminal forensic laboratory," said Haimi, 51, said near his home in southern Israel before departing for another dig in Poland. "After all, it is a murder scene."

BRITAIN: Lighting Hadrian's Wall

A group of American artists is using 450 balloons and thousands of light-emitting diodes to turn the 2,000-year-old Hadrian's Wall into the world's longest work of art. New York digital arts collective YesYesNo was invited by the Olympics-themed summer arts festival to transform the wall, built by Roman invaders to guard the northern frontier of their empire. YesYesNo member Zachary Lieberman, overseeing work on the "Connecting Light" project at Newcastle University, said he hoped to create "the inverse of a border . . . to imagine the border as a means of connection" rather than separation. The work will be staged the nights of Aug. 31 and Sept. 1.
