Two elderly women were out driving in a large car. Both could barely see over the dashboard. As they were cruising along they came to an intersection. The stoplight was red but they just went on through. The woman in the passenger seat thought to herself "I must be losing it, I could have sworn we just went through a red light."
After a few more minutes they came to another intersection and the light was red again and again they went right though. This time the woman in the passenger seat was almost sure that the light had been red but was really concerned that she was losing it. She was getting nervous and decided to pay very close attention to the road and the next intersection to see what was going on.
At the next intersection, sure enough, the light was definitely red and they went right through and she turned to the other woman and said, "Mildred! Did you know we just ran through three red lights in a row! You could have killed us!"
Mildred turned to her and said, "Oh, am I driving?"

DNA structure

In 1953, James Watson and Francis Crick submitted to the journal Nature their first article on the structure of DNA. It was published in the 25 Apr 1953 issue. "We wish to put forward a radically different structure for the salt of deoxyribose nucleic acid. This structure has two helical chains each coiled around the same axis... Both chains follow right-handed helices... The novel feature of the structure is the manner in which the two chains are held together by purine and pyrimidine bases... They are joined together in pairs, a single base from one chain being hydrogen-bonded to a single base from the other chain, so that the two lie side by side with identical z-co-ordinates. One of the pair must be a purine and the other a pyrimidine in order for bonding to occur."«[Image: DNA as illustrated in the Nature article.]
