Casino bus accident leaves three dead

A casino bus full of tourists overturned in northwestern Mississippi on Sunday, killing three people and injuring several others.

The bus belonged to Harrah’s Tunica and was carrying 43 people when it flipped in a median, Tunica County spokesman Larry Liddell said.

Tourists on the bus were headed to the airport for a charter flight to South Carolina, where many were from, officials said.

The bus was the only vehicle involved in the accident, which was still under investigation, Mississippi Highway Patrol Sgt. Leslie White said.

Hackers to fight judge’s order

A federal judge ordered three college students to cancel a Sunday presentation at a computer hackers’ conference showing security flaws in the automated fare system used by Boston’s subway.

The temporary restraining order, issued by a U.S. district judge, prevented the Massachusetts Institute of Technology students from demonstrating how to use the vulnerabilities to get free rides.

The Electronics Frontier Foundation, which is representing MIT students Zack Anderson, R.J. Ryan and Alessandro Chiesa, plans to fight the order, said Jennifer Granick, the group’s civil liberties director.

Electronic copies of the 87-slide presentation circulating on the Internet disparaged the transit system’s physical security and showed photographs of unlocked doors, turnstile control boxes and exposed computer monitors at subway stations.

Scientists forming invisibility materials

Scientists say they are a step closer to developing materials that could render people and objects invisible.

Researchers have shown for the first time they were able to cloak three-dimensional objects using artificially engineered materials that redirect light. Previously they have been able to cloak only two-dimensional objects.

The findings, by scientists at the University of California, Berkeley, led by Xiang Zhang, are to be released later this week in the journals Nature and Science.
