...Gone are the days when the inner workings of automata were hidden to preserve the magic; the cogs, cams, pulleys and levers at "Fantastical Mechanisms" are all part of the show. American artist Norman Tuck offers practical but surprising demonstrations of scientific principles. In Double Helix, for example, two motor-driven copper spirals twine gently within each other until the moment they touch and reverse the motor. The machines of Russian sculptor Eduard Bersudsky, by contrast, are better read as manifestations of the troubled artist's state of mind. Now living in Glasgow, where his works are shown...
...Certainly, defining what we mean when we say life has become a moving target over the years. Are we alive? Yes. Is a virus alive? Maybe. Still, a half-century after the discovery of the double helix, nobody doubts that it is our DNA that determines what we are - in the same way that lines of code determine software or the digital etchings on a CD determine the music you hear. Etch new signals, and you write a new song. That, in genetic terms, is what Venter has done. Working with only the four basic nucleotides that make...
Since discovering the double-helix shape of DNA in 1953, Nobel Laureate James Watson has been a fixture in the news—far too often for his controversial views. Just last month, Watson expressed his belief that black people might have genetically inferior intelligence. In the ensuing uproar, Watson stepped down from his 40-year post as chancellor of the Cold Springs Harbor Laboratory and cancelled the tour for his newly-released book, “Avoid Boring People.” So do the new 368 pages of prose contain any of Watson’s controversial bombs...
...discussed the state of science today. He told the audience that he entered science because “I’d probably fail at anything else,” and, in an interview with The Crimson after his speech, said that as a result of discovering the double-helix, he knew that “I probably didn’t have to worry about my long-term future—someone was always going to hire me.” Over the course of his speech, he mused about why cultures that encourage polygamy thrive...
Nudes were her typicalsubjects, but in 1953, when painter Odile Crick was asked by her husband Francis Crick to illustrate the Nobel-winning discovery he made with James Watson--the structure of DNA--she agreed to pitch in. Her work, the double helix with two spiraling chains of DNA, became an iconic global scientific symbol...
