Astronauts take third spacewalk

CAPE CANAVERAL, Fla. -- A pair of astronauts stepped out on the third and final spacewalk of their shuttle mission Monday, helping to install an enormous oxygen tank at the International Space Station.

Dr. Robert Satcher Jr. and Randolph Bresnik removed the tank from a newly delivered cargo platform on the station, then let a robot arm take it from there.

The tank -- about 5 feet by 6 feet and 1,200 pounds -- was moved and attached to the NASA air lock, a chamber leading out to the vacuum of space. It was filled with high-pressure oxygen for future spacewalks. The spacewalkers hooked up the gas line for the tank, then opened and closed a valve for a leak check.

Feds find drywall, corrosion link

WEST PALM BEACH, Fla. -- The federal government said Monday that it has found a ''strong association'' between problematic imported Chinese drywall and corrosion of pipes and wires, a conclusion that supports complaints by thousands of homeowners over the last year.

In its second report on the potentially defective building materials, the U.S. Consumer Product Safety Commission said its investigation also has found a ''possible'' link between health problems reported by homeowners and hydrogen sulfide gas emitted from the wallboard coupled with formaldehyde, which is commonly found in new houses.

The agency, along with the Environmental Protection Agency and the Centers for Disease Control and Prevention, continues to study the potential health effects.

Funeral held for boy allegedly killed by dad

Hundreds of people attended Jamar Pinkney Jr.'s funeral Monday morning at the Second Ebenezer Church in Detroit. Photos of the boy were projected on large screens above the pulpit.

Three Mile Island radiation caused by pipe cutting

HARRISBURG, Pa. -- Officials are trying to determine how workers cutting a pipe stirred up radioactive dust at the Three Mile Island nuclear power plant.

Plant spokesman Ralph DeSantis said Monday that the public was not endangered Saturday, when a dozen workers were exposed to radiation.

The central Pennsylvania plant has two reactors. One suffered a partial meltdown in 1979 and is mothballed. The other is still in use, but has been shut down since last month so steam generators could be replaced.

Pastor robbed after answering door

LINCOLN, Neb. -- Police in Lincoln, Neb., are investigating the armed robbery of a pastor at his church.

Police said the pastor, 52-year-old Christopher Anderson, opened a door at Glad Tidings Assembly of God for someone who was knocking late Saturday night. The man asked for money, but Anderson said he didn't have any to give.

Anderson told police that when he started to close the door, the man grabbed him by the hair and slammed his face against a table.

Police say the robber held a knife to the pastor's face as he took his wallet, watch and gold wedding ring.
