A bug's life: Exceptional genomic stability yet rapid protein evolution in a carpenter ant mutualist

...genome evolution in the context of a host-symbiont relationship emerges. As Wernegreen and her colleagues explain in their Genome Research article, long-term genome stasis is a striking characteristic of insect mutualists, and it may severely constrain the evolutionary potential of these symbiotic microbes. Howe...

A little telomerase isn't enough

...stine among them. "We thought there might be some relationship between telomerase, telomere length and the survival of stem cells, but it was really exciting to see it," says Greider. When the researchers looked at fifth-generation mice that had by chance inherited their parents' good telomerase copies, giving ...

Plant gene related to cancer treatment may foster new oncology drugs

...ts of the two studies suggest a previously unknown relationship between two protein families involved in this process, he said. Working together, the proteins apparently move molecules of the plant growth hormone auxin through cell walls. In humans, related proteins rid cells of toxins such as cancer drugs. "The...

Center releases new public survey on stem cells

...'s views about the moral status of embryos and the relationship of those views to ESC research policy preferences has not been fully explored. The survey showed that nearly the same number of Americans believe that an embryo in a Petri dish has no or low moral status (30 percent) or maximum moral status (28 perc...

Birds have been thought to be related to theropod dinosaurs because both groups have a hand reduced to three digits. Theropods are known from fossil evidenc...

Researchers show how air pollution can cause heart disease

.... The results added up to a clear cause and effect relationship between PM2.5 exposure and atherosclerosis, according to the study.
