that likewise mediate carbon and sulfur cycling in the ocean. Moran continued, "Admittedly, this is not the only bacterium that influences gas exchange between the ocean and atmosphere, but once we understand how S. pomeroyi functions, we can apply t...
Potent anticancer drug increases function of axons in mouse model of neurodegeneration
...s derived from plants (taxol) and other biological organisms
such as sponges (discodermolides) have been used as anti-cancer drugs because they prevent cells from dividing. They do this by keeping microtubules stabilized, which blocks cell division and causes cell death. Microtubules are protein structures fou...

develop from comparable numbers and types of genes has been a major question since the genetic similarity was discovered. Scientists are trying to understand what turns a gene "off" or "on", or alters its activity when "on" in other words, the pro...

Immune system contributes to evolution of a new fluorescent protein
...that if you induce too much mutation, you kill the organisms
because you're frying all the genes they need," he said. "What we really wanted was an organism with cells that could rapidly produce mutations and target them to one specific gene," said Tsien. "To our surprise, that organism is us." SHM produces mu...

Human complexity and diversity spring from a surprisingly few (relatively speaking) genes
