CSU biologists have traced the stability of plant mitochondrial genomes to a particular gene - MSH1 - that plants have but animals don't. Their experiments, described in Proceedings of the National Academy of Sciences, could lend insight into why animal mitochondrial genomes tend to mutate.
Researchers have developed a simple model to study how ants balance their large heads relative to their body size. Such models may have useful applications in bio-inspired designs.
Over time goldenrod plants and the gall flies that feed on them have been one-upping each other in an ongoing competition for survival. Now, a team of researchers has discovered that by detecting the plants' chemical defenses, the insects may have taken the lead.
Lung cancer in non-smokers is a biologically distinct disease from that in smokers, according to a new study. Researchers also found that non-smokers have signs of genetic damage from environmental carcinogens and that some cancers look molecularly like more advanced disease - with characteristics that could be targeted with tailored treatments.
The evolution of our teeth began among ancient armoured fishes more than 400 million years ago. In the scientific journal Science, an international team led by researchers from Uppsala University presents ground-breaking findings about these earliest jawed vertebrates. Using powerful X-ray imaging, they show that unique fossils found near Prague contain surprisingly modern-looking teeth.
How does evolution impact ecological patterns? It helps smooth out the rough edges, says UConn Ecology and Evolutionary Biology Professor Mark Urban. Urban led an international team of researchers through a review of the history of ecological and evolutionary research to establish a framework to better understand evolution's impact on ecosystem patterns. The research is published as a perspective in the Proceeding of the National Academy of Sciences.
A report in the journal Current Biology on July 9 offers a detailed description of the first nearly complete skeleton of an extinct large dolphin, discovered in what is now South Carolina. The 15-foot-long dolphin (Ankylorhiza tiedemani comb. n.) lived during the Oligocene--about 25 million years ago--and was previously known only from a partial rostrum (snout) fossil.
Several species of fish have adapted to harsh environments using the same mechanism, which brings to question evolutionary chance, according to a study by Kansas State University and Washington State University.
Evolutionary biologists from the University of Konstanz resolve a century-old question regarding the asymmetric genitals of internally fertilizing fishes of the family Anablepidae. Surprisingly, the direction of genital asymmetry in these fishes is random rather than hereditary.
Large blocks of 'plug and play' genes play a super-sized role in adaption-and may help fill lingering gaps in Darwin's theories
