    Enlarge Image Greedy guest. Fungi (blue lines) living among the cells of a grass cause that plant to make more seeds and less pollen. Credit: Jennifer Rudgers Life demands tradeoffs, and plants are no exception. Virginia wildrye, common on U.S. prairies and rangelands, often plays host to a fungus that helps this grass grow. But the plant pays a price. Researchers have discovered that infected plants produce less pollen than their noninfected counterparts. Instead, the fungus causes the rye grass to make extra seeds, which transmit the fungus to the next generation and new locations. This is the first...

    Scientists have stumbled across the first example of a photosynthetic organism living inside a vertebrate's cells. The discovery is a surprise because the adaptive immune systems of vertebrates generally destroy foreign biological material.

Little did I know that walking next to me in the halls of Olympus High School that year was a friend who would shape history in 2004 as profoundly as these events did in 1968, the year Karl Rove and I were 17. Karl started out with every social disadvantage.
