The brightest dog
Two dog owners were bragging about the intelligence of their pets. “The brightest dog I ever had,” said one, “was a Great Dane that used to play cards. He was great at poker, but finally a friend complained about him and I had to get rid of him.”
“You got rid of him, a bright dog like that?” exclaimed his friend. “A dog like that would be worth millions.”
“Had to,” the first man replied. “I caught him cheating.”

Medical research reactorIn 1959, at Brookhaven National Laboratory in Upton, N.Y., the first U.S. atomic reactor built specifically for medical research, Brookhaven Medical Research Reactor, reached criticality. The BMRR was a 5 megawatt, modified tank-type reactor, which superceded the Brookfield Graphite Research Reactor. It produced a neutron flux of as many as 20 trillion neutrons per square centimeter per second. The reactor was mainly used for developing and testing boron neutron capture therapy (BNCT), a promising treatment for patients with a deadly form of brain cancer called glioblastoma multiforme. BNCT uses radiation and a boron compound to destroy cancer cells while leaving healthy cells intact. Use of the reactor ceased in Dec 2000.« |
