Silencing of the gene that encodes the cancer-suppressing protein APC is common in people with esophageal cancer, suggesting that physicians might use this genetic abnormality as a marker for the disease. (p. 381)
-
When laboratory vortices are mixed to create the equivalent of a tornado in a hurricane, the "hurricane" may gobble up spots of calm from the outside world. (p. 381)
