A scientific finding that demonstrates specific genes influencing the effect of dietary nutrition on immunity provides insights that may one day inform personalized medicine.
Indoor spaces offer a new research frontier for studies in ecology and evolutionary biology of organisms that live inside built environments, according to a paper authored by a Cornell graduate student.
Researchers have discovered that patches of waterlogged soil in forested watersheds act as hot spots of microbial activity that remove nitrogen from groundwater and return it to the atmosphere.
Holding children back a year from entering kindergarten has no impact on their ultimate performance in graduate school, and could lead to a loss in income, researchers Kevin Kniffin and Drew Hanks find.
