...BIRTHDAY CELEBRATED. By HARRIET, 175, a giant Gal?pagos tortoise and the world's oldest known animal; in Canberra, Australia. While there is some dispute over Harriet's exact age and the claim that she was brought from the Gal?pagos Islands by Charles Darwin, DNA evidence suggests that she was born before the famed naturalist's 1835 expedition, which would make her at least 170. Harriet, who for more than a century was believed to be a male and went by the name Harry, marked the occasion with a snack of pink hibiscus flowers...
SPIRAL SPECTACLE A 3-D model of the DNA double helix showcases a novel way of projecting videos along an installation's curved walls
...continent where land was often given away. That have-it-all ethos persists today, even though the resource freebies are long since gone. Other countries--where the acreage is smaller and the pickings are slimmer--came of age differently, with the need to cooperate getting etched into the cultural DNA. The American model has produced wealth, but it has come at a price--with ambition sometimes turning back on the ambitious and consuming them whole...
...Great Gene Hunt. It was an extraordinarily productive year for the genetic engineers racing to unravel the secrets of human DNA. Scientists not only pinpointed genes linked to more than half a dozen major ailments -- including Lou Gehrig's disease, Huntington's disease, colon cancer, hyperactivity and a type of diabetes -- but also sketched out the first rough map of all human chromosomes. Other researchers explored ways to use this information to replace damaged genes. The first beneficiaries of ''gene therapy'' -- two Ohio girls who have an immune-deficiency disease -- made their public debut after three years of successful treatment...
...Ancient Genes The premise of Jurassic Park -- that material from blood cells found in the thorax of a prehistoric fly might be cloned to re-create a living dinosaur -- was echoed eerily in the science journals. Not only did scientists extract bits of DNA from the bone marrow of a 65 million-year-old Tyrannosaurus rex fossil, but they also recovered intact DNA from an insect trapped in amber back in the Mesozoic era, 130 million years...
