...became apparent to us that there was going to be this virtual tsunami of 3-D television sets hitting the marketplace," says Sean Bratches, ESPN's executive president for sales and marketing, who has played a major role in the network's 3-D initiative. "There's probably no better genre than sports for 3-D." (See the top 10 TV series...
...Make a Better Mouse As momentous as epigenetics sounds, the chemistry of at least one of its mechanisms is fairly simple. Darwin taught us that it takes many generations for a genome to evolve, but researchers have found that it takes only the addition of a methyl group to change an epigenome. A methyl group is a basic unit in organic chemistry: one carbon atom attached to three hydrogen atoms. When a methyl group attaches to a specific spot on a gene - a process called DNA methylation - it can change the gene's expression, turning it off or on, dampening...
...contrast, Darwin argued that evolution works not through the fire of effort but through cold, impartial selection. By Darwinist thinking, giraffes got their long necks over millennia because genes for long necks had, very slowly, gained advantage. Darwin, who was 84 years younger than Lamarck, was the better scientist, and he won the day. Lamarckian evolution came to be seen as a scientific blunder. Yet epigenetics is now forcing scientists to re-evaluate Lamarck's ideas. (See TIME's video on Charles Darwin and Abraham Lincoln...
...enter puberty. Boys are genetically isolated before puberty because they cannot form sperm. (Girls, by contrast, have their eggs from birth.) That makes the period around puberty fertile ground for epigenetic changes: If the environment is going to imprint epigenetic marks on genes in the Y chromosome, what better time to do it than when sperm is first starting to form...
...column, "Seeing Customers as Partners in Invention," Tripsas wrote that 3M was "at the forefront of a movement" in which companies better tailored products to clients by engaging with them in person and soliciting customer input during product development. 3M paid $820 in airfare and accommodation expenses for Tripsas' visit to the company's St. Paul headquarters...
