...Waldman will lead a one-and-a-half hour, non-credit study group that will meet twice a week. The study group will focus on the art of speechwriting...
...scientists based at M.I.T.'s Whitehead Institute for Biomedical Research has finally managed to make human cells malignant--a feat they accomplished with two different cell types by inserting just three altered genes into their DNA. While these manipulations were done only in lab dishes and won't lead to any immediate treatment, they appear to be a crucial step in understanding the disease. This is a "landmark paper," wrote Jonathan Weitzman and Moshe Yaniv of the Pasteur Institute in Paris, in an accompanying commentary...
...substances meant to rein in excessive division; and a third that promotes the production of telomerase, which made the cells essentially immortal. They'd created a tumor in a test tube. "Some people believed that telomerase wasn't that important," says the Whitehead's William Hahn, the study's lead author. "This allows us to say with some certainty that...
...same as understanding how it behaves in a living body, of course. But by teasing out the key differences between normal and malignant cells, doctors may someday be able to design tests to pick up cancer in its earliest stages. The finding could also lead to drugs tailored to attack specific types of cancer, thereby lessening our dependence on tissue-destroying chemotherapy and radiation. Beyond that, the Whitehead research suggests that this stubbornly complex disease may have a simple origin, and the identification of that origin may turn out to be the most important step...
When Johnson and her fellow employees return to the office after a day of climbing, falling and even drumming--in an exercise lead by Village Music Circles of Santa Cruz, Calif.--the excitement still resonates. Even 10 days later, "People are walking through the halls high-fiving each other," says Johnson. "The atmosphere here is just joyous." To keep it that way, Adlink managers are planning another offsite next year. And they've invited the Orion Learning trainers to follow up with quarterly visits to Adlink headquarters, where they will use slogans and short exercises to refresh the staff...
