Nearly 2,000 current and former Los Alamos National Laboratory employees and visitors may have been exposed to beryllium in the lab and may be at risk of disease.

Beryllium is an extremely light, hard, non-radioactive silver-gray metal that is purified to use in nuclear weapons and reactors, aerospace work, electronics, golf clubs and bicycle frames. However, in a particulate or finely powdered form it is hazardous and can cause chronic beryllium disease that impairs lung function.

A hoard of prehistoric gold coins - believed to be the biggest yet - was discovered by a treasure hunter in Britain.

The lucky find composed of 824 gold coins buried in a broken pottery jar was found in a field near Wickham Market, Suffolk by means of a metal detector.

A nine-year-old Hillsboro, Texas boy, whose head was detached in a car accident three months ago, has miraculously survived and is recovering after doctors reattached his skull to his spine.

"As far as I'm concerned, he has a full recovery -- he is neurologically intact. He walks -- that's one of the biggest things. He isn't weak and is active; it's amazing," Dr. Richard Roberts, the pediatric surgeon who led an operation to reattach the skull of Jordan Taylor to his spine with a metal plate and titanium rods, told CBS News on Monday. "He's done better than anyone thought he would. His injury is normally catastrophic, fatal, and he managed to survive."

Britain's Queen Elizabeth has had her teapot confiscated by the secret service amid fears it could contain a listening device hidden by Russian spies.

The monarch - who received the ornate samovar, a metal container used to heat water in Russia, as a gift nearly 20 years ago - was warned the gift could have been used by spies intending to overhear her conversations with prime ministers and world leaders, as well as more intimate conversations with family and friends.

After several months of battling thousands of pigeons hovering over Piazza San Marco, Venice has declared victory. From 20,000 the canal city's pigeon population has dwindled to less than 1,000.

City officials attribute the change to a campaign they launched in May to ban vendors who sell bird feed to tourists. While the friendly birds are considered a tourist attraction too, next to Venice's famous canals and gondola rides, the pigeons destroy the centuries-old statues and buildings when they peck at corners to reach for food thrown by tourists. The birds' droppings on the landmarks have also been blamed for eroding the metal material on some of the landmarks.
