The doctor answered the phone...

The doctor answered the phone and heard the familiar voice of a colleague on the other end of the line. "We need a fourth for poker," said the friend.
"I'll be right over," whispered the doctor.
As he was putting on his coat, his wife asked, "Is it serious?"
"Oh yes, quite serious," said the doctor gravely. "In fact, there are three doctors there already!"

Chondrite meteor

In 1806, a 6-kg chondrite meteorite - carrying carbon-based, organic chemicals - was unequivocally identified for the first time. Its arrival on earth was noted at 5:30 pm, outside Alais, France. The organic chemicals it carried suggested the possibility of life on whatever body was the source, somewhere in the universe. According to the observations of Berzelius and a commission appointed by the French Academy it “emits a faint bituminous substance” when heated. Berzelius reported his analysis of the Alais meteorite in 1833 that destructive distillation yielded a blackish substance, indiginous water, carbon dioxide gas, a soluble salt containing ammonia, and a blackish-brown sublimate, which Berzelius confessed was unknown to him.
