Penn researchers explore the role of cell suicide in the development and treatment of cancer

...of the mechanism function, the researchers hope to map out new ways to correct for the mechanism when it fails. To look at it broadly, there are only two major types of diseases: ones where cells are killed and ones where cells refuse to die, said Thompson. Cancer is one of the latter it occurs when di...

New study puts dinosaur noses in their place

...ssils from dozens of dinosaurs, Witmer was able to map the likely position of cartilage, blood vessels and other soft tissues that made up the nasal cavity of dinosaurs. "We looked at as many modern-day animals as we could get a hold of," Witmer said, "and found an extraordinary amount of evidence to su...

...s Aroian. "We have a complete genetic and physical map of C. elegans, we can breed them in the laboratory easily, they grow fast, having only a three-and-a-half day life cycle, theyre transparent, so we can easily see their internal structures and they eat bacteria, so we can express the Bt toxin rig...

Trouble in paradise? 'Natural' pest control requires careful planning, Science authors conclude

Better computer modeling provides a new look at large biomolecules

...s and the other with 94,854, revealed an intricate map of positive and negative potential that could yield insights into the function of ribosomes, said the scientists. According to McCammon, software using the new approach will soon be made available to experimental molecular biologists to help guide th...

New epilepsy gene identified in mice

... search, Ptacek and his colleagues then set out to map this locus finely enough to identify the specific causative gene. "It was just a matter of brute force, in which we generated a colony of twelve hundred mice and performed genotyping on them to home in on the gene," said Ptacek. "Eventually, we local...
