New Scientist has a piece on the uncommon art of forensic astronomy. Texas State University physicist Donald Olson has solved the mystery of Walt Whitman's meteor poem, thanks to clues found in an 1860 painting by Frederic Church. "Before we were done we had collected 300 records of observations [of the event]. I think this may be the most observed, and most documented, single meteor event in history. From the Great Lakes to New England, every town that had a newspaper wrote about that meteor. ... So we've got one of America's greatest landscape artists, Frederic Church, watching the meteor from Catskill, and we've got one of America's greatest poets, Walt Whitman, watching the meteor from New York City." The field of forensic astronomy may have gotten its start more than 30 years before, when art historian Roberta Olson argued convincingly that the lifelike comet in Giotto's "Adoration of the Magi" in Padua, Italy, in fact depicted Halley's Comet in its visitation of 1301.

laggist writes "A heart patient in Singapore has been implanted with an artificial heart that pumps blood continuously, allowing her to live without a pulse. From the article: '... the petite Madam Salina, who suffers from end-stage heart failure, would not have been able to use the older and bulkier models because they can only be implanted in patients 1.7m or taller. The 30-year-old administrative assistant is the first recipient here to get a new artificial heart that pumps blood continuously, the reason why there are no beats on her wrist.'" The story is light on details, but an article from last year in MIT's Technology Review explains a bit more about how a pulse-less artificial heart works.
