Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

For the first time, researchers have observed exactly how some cells are able to repair DNA damage caused by the sun's ultraviolet (UV) radiation. This enzyme is missing in all mammals, including humans, although all plants and all other animals have it. Greater un...

A first glimpse of the influenza replication machine

In 1918, 50 million people died during a worldwide influenza pandemic caused by mutation of a bird-specific strain of the influenza virus. Recently H5N1, another highly infectious avian strain has caused outbreaks of bird flu around the world. There is great concern that this virus might also mutate to allow human-to-human transmission and cause another catastrophic pandemic. Specific mutations i...

RNA enzyme structure offers a glimpse into the origins of life

Researchers at the University of California, Santa Cruz, have determined the three-dimensional structure of an RNA enzyme, or "ribozyme," that carries out a fundamental reaction required to make new RNA molecules. Their results provide insight into what may have been the first self-replicating molecule to arise billions of years ago on the evolutionary path toward the emergence of life. In...
