NEWSLETTER - 20 MAY

Feature for Today

On 20 May 1537, Hieronymus Fabricius was born, an outstanding Renaissance anatomist who helped found modern embryology.

He published a book on the valves in veins, which influenced his pupil William Harvey to delve further into the circulation of blood.

Fabricius studied the development of the chick embryo in the egg, and published two books on the subject. In all, he published over a dozen medical works, which were translated and reprinted long after his death. One curious piece was an essay on the language of brutes.

For more on his productive life, read Biography of Hieronymus Fabricius, from Annals of Anatomy and Surgery (1880).

Book of the Day

On 20 May 1918, Edward B. Lewis was born, an American developmental geneticist who was shared the 1995 Nobel Prize for Physiology or Medicine for discovering the functions that control early embryonic development. Lewis studied in fruit flies and their homeotic genes that govern the development of a larval segment into a specific body segment. He also made pioneering studies on ionizing radiation and human cancer. In doing so, he was propelled into a public storm over nuclear weapons testing policy. Today's Science Store pick is: Genes, Development and Cancer: The Life and Work of Edward B. Lewis, by Howard D. Lipshitz (ed.). The editor has collected Lewis' key publications and provided commentary giving scientific and historical context, with insight into Lewis' insight and motivations. New Price $79.95. Also available Used from $8.25 (as of time of writing).

Yesterday's pick: Science Is Not a Quiet Life: Unravelling the Atomic Mechanism of Haemoglobin, by Max F. Perutz (ed.).

Quotations for Today
Congreve	"What opposite discoveries we have seen! (Signs of true genius, and of empty pockets.) One makes new noses, one a guillotine, One breaks your bones, one sets them in their sockets; But vaccination certainly has been A kind antithesis to Congreve's rockets, ..." - Lord George Gordon Byron referring to Sir William Congreve, English artillery officer (born 20 May 1772)
	"In science 'fact' can only mean 'confirmed to such a degree that it would be perverse to withhold provisional assent'. I suppose that apples might start to rise tomorrow, but the possibility does not merit equal time in physics classrooms." - Stephen Jay Gould, American palaeontologist, evolutionary biologist, science historian and author (died 20 May 2002)
	"The number of hypotheses and theories about climate change are numerous. Quite naturally they have caught the public attention, as any proof of past climactic change points to the possibility of future climate change, which inevitably will have significant implications for global economics." - Eduard Brückner, German climatologist (died 20 May 1927)

QUIZ
Before you look at today's web page, see if you can answer some of these questions about the events that happened on this day. Some of the names are very familiar. Others will likely stump you. Tickle your curiosity with these questions, then check your answers on today's web page.
Births
	William Redington Hewlett, born 20 May 1913, was an American electrical engineer who co-founded a leading manufacturer computers, computer printers, and analytic and measuring equipment. In 1939, he formed a partnership with a Stanford classmate. Their first product was an audio oscillator. Eight were sold to Walt Disney for Fantasia. Lesser-known early products were: bowling alley foul-line indicator, automatic urinal flusher, weight-loss shock machine. The company's first "plant" was a small garage in Palo Alto, with $538 initial capital. *What is the name of the computer company he co-founded?*
	Emil Berliner, born 20 May 1851, was a German-born American inventor who made important contributions to telephone technology, but had a more familiar invention which displaced Edison's product. *What was his invention?*
Deaths
	Helen Brooke Taussig (1898-1986) was an American physician who was the founder of pediatric cardiology. She pioneered using X-rays and fluoroscopy to identify heart defects in newborns. In the 1940s, she and surgeon Alfred Blalock developed a surgical procedure for treating blue baby syndrome. In the early 1960s, Taussig was a major person in revealing and stopping the harm caused by a certain sedative drug which when taken by pregnant woman caused terrible deformations of their to newborn children. *What was this sedative drug?*
	Charles Bonnet (1720-1793) was a Swiss naturalist and philosophical writer who discovered parthenogenesis (reproduction without fertilization) in certain life forms. Bonnet also demonstrated the regenerative ability of annelid worms, found that insects breathe through pores which he called stigmata, studied photosynthesis and epinasty in plants and noted the emission of bubbles by a submerged illuminated leaf. *In what life form did he discover parthenogenesis?*
Events
	On 20 May 1747, an experiment to remedy an illness found among sailors was begun by a British ship's surgeon, James Lind, on the HMS Salisbury. He regulated the diets of the sailors, and especially included lemons and oranges. Positive results quickly showed that the illness, and the huge numbers of deaths, could be easily remedied in this way. What was the illness?
	On 20 May 1932, a female pilot took off for Ireland from Habor Grace, Newfoundland, to become the first woman to fly solo across the Atlantic Ocean. She later landed her plane in Ireland after a thirteen-hour, thirty-minute flight from Canada. What is the name of this woman?
	On 20 May 1927, at 7:40 a.m., a male pilot took off from Roosevelt Field in Long Island, N.Y., in a monoplane on his historic first solo flight across the Atlantic Ocean. He arrived in France thirty-three and one-half hours later. What is the name of this man?
