George Hoyt Whipple (1878) Whipple was a US pathologist, who, together with colleagues, discovered that a diet including raw liver could treat pernicious anemia, then a fatal disease. For his efforts, he shared a 1934 Nobel Prize. Whipple's study of bile pigments led to an interest in how the body makes hemoglobin, and his experiments in artificial anemia established iron as the most potent inorganic factor in the formation of red blood cells. He was also the first person to describe what previously unknown disease? Discuss
Georg Wilhelm Friedrich Hegel (1770) Hegel was an influential German philosopher who developed the Hegelian dialectic, according to which a thesis, such as "being," inevitably generates its antithesis, "not-being." The interaction of the two forms a synthesis, "becoming," which, in turn, becomes a new thesis that generates an antithesis, and so on. He used the dialectic to explain everything from nature to history, interpreting the French Revolution as a thesis that generated its antithesis, known as what period in French history?
Julio Cortázar (1914) Cortázar was an Argentinean novelist who gained recognition as one of the century's major experimental writers. A permanent resident of France after 1951, his works reflect his interest in French Surrealism, psychoanalysis, photography, jazz, and revolutionary Latin American politics. His masterpiece, Rayuela—translated as Hopscotch—creates a world in which eroticism, humor, and play offer solace for life's cruelty and despair. What is unique about the novel's structure?
Flower Power: Dandelion Tires Dandelions are widely considered pesky weeds, but they have numerous uses, some of which we are just beginning to capitalize on. Until now, the tire industry has relied entirely on rubber-tree plantations in Southeast Asia for its natural rubber. However, researchers have been working to breed a type of dandelion native to Kazakhstan that yields tire-grade rubber and have achieved per-hectare yields on par with rubber-tree plantations, suggesting the flower is a viable alternative source of natural rubber. It may not be long before dandelion fields begin cropping up across the US and Europe to keep the wheels of the tire industry turning.
Efforts to Curb Youth Smoking Meeting Their Match in E-Cigarettes Decades of efforts to curb youth smoking in the US have made considerable gains, with the rate of teen smoking falling to a record low of just 15.7 percent in 2013. But these gains could be short-lived thanks to the surge in popularity of electronic cigarettes. The number of US adolescents and teens who have never smoked conventional cigarettes but have tried e-cigarettes is on the rise, with more than a quarter million using them in 2013, a threefold increase from 2011. Those who have tried e-cigarettes also express a greater willingness to try regular cigarettes in the relatively near future.
