Scientists sequence genome of kind of organism central to biosphere's carbon cycle
...her new finding reported in Science concerns the unusual
way the diatom metabolizes silicon to form its characteristically ornate silica frustule. "Diatoms can manipulate silica in ways that nanotechnologists can only dream about. If we understood how they can design and build their patterned frustule as...
Researchers find color sensitive atomic switch in bacteria
...." Spudich said. That function makes the protein unusual
among its family of light-sensing proteins known as rhodopsins, which are present in microbes and higher animals. In human eyes, rhodopsin is the light-absorbing pigment of the rods, located in the retina. The team studied a new-found rhodopsin on ...

success story and there's an awful lot we can learn there," he says. "The important thing is these guys imposed these rules on themselves. It's an interesting, interesting industry," and the lessons we can learn from this industry can be applied to m...
Master of antimalarial resistance
...rasites lost their resistance to chloroquine. This unusual
pattern--gaining resistance to one drug while simultaneously losing resistance to another--may shed light on the exact role that pfcrt plays in resistance, according to Fidock and colleagues. When a human is infected with malaria, the parasite lodges...
New fossil sheds light on old mystery

neck morphology of Dinocephalosaurus would have allowed it to suction feed, a feeding mode previously unknown for fossil aquatic reptiles," said Michael LaBarbera, PhD, professor of organismal biology and anatomy at the University of Chicago. "But su...

properties of the ocean crust in the Lau Basin, we can expect to discover new species there--species that perhaps will hold new and unique secrets to share with us," Fisher said. "The microbes at sites like these--thriving in super-hot temperatures-...

community, sort of upside-down, in the sense that the children lead the way. The children are the most fluent users of the language, not the older adults," Senghas said. The researchers studied a trait central to all developed languages called "discr...

because it will examine both the natural and the human factors that spread transgenes from engineered crops into non-engineered crops and natural populations. "This hasn't been done before, and I'm excited to get started," said Norman Ellstrand, a p...
