A few minutes from the University of Pennsylvania campus in Philadelphia sits a small peach orchard that’s home to some unusual experiments. Contrary to first appearances, the subjects of the experiments are not the peach trees themselves, each of which is protected by a two-meter-cubed tent of fine mesh material. Instead, researchers are interested in the hundreds of tiny fruit flies living on the trees and the even tinier bacteria living inside the insects’ guts.
The setup was designed with a deceptively simple question in mind: Do the microbes in an animal’s digestive tract help shape their host’s evolution? Evolutionary biologist Seth Rudman says that it would make sense if they did. “Microbiomes [can have] a huge effect on host fitness, and hence could have a huge effect on adaptive trajectories of populations,” says Rudman, who helped construct part of the site in 2017 while a postdoc in evolutionary ecologist Paul Schmidt’s lab at UPenn. Despite broad scientific
Maternal Omega 3-rich diet may reduce onset of breast cancer in offspring
According to researchers at Marshall University, a maternal diet rich in Omega-3 fatty acids protects from breast cancer development in offspring. In a new study recently published by
Frontiers in Cell and Developmental Biology, researchers noted a significant difference in mice from mothers that were fed a diet rich in canola oil, compared with mothers fed a diet rich in corn oil. A maternal Omega 3-rich diet affected genome-wide epigenetic landscape changes in offspring and potentially modulated gene expression patterns.
Dr. Ata Abbas, a former postdoctoral research fellow in Marshall s Department of Biological Sciences, headed a research team under the leadership of Dr. Philippe Georgel in the College of Science. Research was done in the Cell Differentiation and Development Center at Marshall as part of a collaborative effort with the Joan C. Edwards School of Medicine s Department of Biochemistry and Mi
